Base of a clamp and a clamp applying the same

The present invention relates to a jig, and more particularly to a jig that mites two sheets of material, and a base of such a jig.

According to the wood or stone products, it is often necessary to slant the two plates at a specific angle, for example, an angle of ninety degrees. The two plates each have a beveled edge. When combined, the adhesive is applied to at least one beveled edge, and then the beveled edges of the two plates are attached and fixed by a clamp. After the adhesive is hardened, the two plates are completed. The combination.

Conventional clamps for clamping and securing panels are in the form of a C-shape; and clamps of the other are clamps with movable clamp arms.

The movable clamp has a main frame and a clamping arm mounted on the main frame and movable, and the clamping arm is moved to a clamping position, and the two plates can be fixed between the main frame and the clamping arm, and The beveled edges of the two sheets are bonded together.

However, in the current operation of the movable fixture, the operator must repeatedly adjust and calibrate the position of the two plates, which can accurately combine the oblique sides of the two plates, which is quite cumbersome, inconvenient and time consuming in operation, and the effect is effective. Not good. Furthermore, it is not convenient to fix such a jig to a clamping position.

SUMMARY OF THE INVENTION A primary object of the present invention is to provide a clamp for clamping two sheets of material for engagement, which allows the operator to quickly and accurately mate the two sheets without the need for repeated correction.

When the base is in the closed position, the limit member is moved into the base and abuts against the link assembly, so that the link assembly loses the degree of freedom of displacement, and the base can be locked in the closed position; The limit member moves outward a short distance and no longer resists the link assembly, the link assembly returns the displaceable degree of freedom so that the base is no longer locked in the closed position.

The present invention further provides a clamp for applying the aforementioned base for slanting the two sheets so that the clamp can be quickly locked in the closed position or released from the closed position. The fixture further includes: two plate abutting members respectively pivoted on the rocker arm and the base, and when the clamp is in the open position, two plates can be respectively placed on the base and the rocker arm, and The two plates are respectively positioned in a correct joint position by the two plate abutting members; then, when the clamp is operated to the closed position, the oblique sides of the two plates can be accurately butted.

The jig further includes a clamping seat and a post connected to the clamping seat by the connecting rod, and the clamping device is mounted on the frame to perform the bonding work of the plate.

For a better understanding of the objects, features, and advantages of the present invention, the present invention will be described in detail with reference to the accompanying drawings.

Please refer to the first to fourth figures, which are a clamp (10) according to a preferred embodiment of the present invention, for slanting two plates, comprising: a base (15) disposed on the base (15) The upper two plate abutting members (60) (70) and a clamping mechanism (80), a post (140), a clamping seat (160), and a casing.

The base (15) has a base (20), a rocker arm (30) pivotally connected to the base, and a limiting mechanism (50). The base (20) can be of any configuration, not limited to the elongated shape of the embodiment, and the rear end thereof is a pivot end (22).

The bottom end of the rocker arm (30) is pivotally connected to the pivot end (22) of the base (20), and is pivotable relative to the base. Referring to the fourth to seventh embodiments, the rocker arm (30) of the embodiment has a main frame (31) and a frame (40). In detail, the main frame (31) is a standing body, The bottom end is a pivot end (32) and is provided with a point hole (33); the frame (40) is a left-right symmetric configuration having two side walls (41); a point hole (42) is disposed at the bottom The bottom side of the frame (40) extends through the two side walls (41); the two fingers (43) are respectively disposed at the bottom ends of the two side walls (41) and lower than the fulcrum holes (42). The main frame (31) is nested in the frame (40) (the two side walls (41) are located on two sides of the main frame (31)); a pivot (35) pivotally connected to the two pivot holes (33) (42), the frame (40) is coaxially pivoted to the main frame (31). An adjustment mechanism (45), as shown in the seventh figure, has an adjusting screw (46) and a rod member (47) which is disposed between the two side walls (41) of the frame (40). One of the pivot holes (411) is rotatable in the pivot hole (411); the adjusting screw (46) is inserted into the adjusting hole (for a fish eye hole) (36) of the main frame (31), and is adjusted The head (461) of the screw is limited by a pin (37), so that the adjusting screw can only rotate in the adjusting hole without coming out of the adjusting hole; the screw portion (462) of the adjusting screw is screwed to the rod ( 47) Screw hole (471). When the adjusting screw (46) is rotated, the frame (40) can be angularly displaced on the main frame (31) with the pivot (35) as the center of rotation, as in the imaginary line of the seventh figure.

The rocker arm (30) is pivotally connected to the pivot hole (24) of the pivot end (22) of the base (20) by the pivot (35), as shown in the fifth figure, so that the base and the rocker arm are opposite angles. Displacement, the rocker arm can swing to the closed position of the fifth figure; or, as in the eighth and ninth figures, in an open position.

Referring to the fourth, fifth and seventh figures, the limiting mechanism (50) has a connecting rod assembly and a limiting member (56). The connecting rod assembly includes a first connecting rod (52) and a second connecting rod (54). The first link (52) is pivotally connected to the rear end of the base (20) by a first pivot pin (521); the top end of the second link (54) is pivoted (53) The main frame (31) is pivotally connected to the rocker arm (30), and the bottom end of the second link is pivotally connected to the front end of the first link (52) by a second pivot pin (541). a stop portion (55) protruding from the front surface of the second link (54), located at a top pivotal end of the link (54) (ie, where the pivot (53)) and the bottom pivot end (ie where the pivot pin (541) is). Preferably, a space (301) is disposed at a bottom end of the main frame (31); the connecting rod assembly is received in the space (301). The limiting member (56) is disposed on the base (15) and can be moved into or out of the base to be in contact with the connecting rod assembly. The limiting member (56) is a screw in the embodiment, and is screwed from the bottom to the screw hole (25) provided in the base (20), and the limiting member (56) can be moved into or out of the base. The inner end (57) can be pressed against the link assembly so that the rocker arm cannot swing.

The tenth figure shows that the base (15) is not in the closed position, and when the rocker arm (30) is swung in the state of the base (20), the linkage assembly is moved with the angular displacement of the rocker arm, and the second connection When the stop portion (55) of the rod (54) touches the front end of the first link (52), as shown in the fifth figure, the two links (54) (52) reach the displacement stop point, and the rocker arm cannot The angular displacement continues counterclockwise, at which point the base (15) is in the closed position. During the swinging of the rocker arm from the non-closed position to the closed position, the top pivoting end of the second link (54) (the pivot (53)) will pass the highest point of its angular displacement stroke (Note; when When the top pivoting end is located directly above the bottom pivoting end of the second link (54) (the second pivot pin (541)), it is the highest point of the top pivoting end), and the second link (54) After the highest point is reached, the dead center portion (55) starts to contact the top surface of the first connecting rod (52). At this time, according to the fifth figure, the top pivoting end is located at the bottom of the bottom pivoting end. The left side of the line (V) is no longer at the highest point of its angular displacement stroke. When the rocker arm (30) is in the closed position, the limit member (56) is rotated upward to move the inner end (57) toward the link assembly and against the slope of the bottom surface of the first link (52) (522) As shown in the fifth figure, at this time, the first link (52) can neither move up nor down, causing the top pivotal end of the second link (54) to move neither clockwise nor counterclockwise. In other words, the top pivotal end of the second link is restricted from moving in a clockwise direction, and thus cannot pass the highest point and remains in the locked state of the fifth figure; thereby, the link assembly has no displaceable degree of freedom. The rocker arm (30) is locked in the closed position and cannot swing. It can be understood that, in design, the limiting member is biased against the second link (54), and the rocker arm can also be locked in the closed position.

When the restriction member (56) is loosened so as not to abut against the first link (52), the link assembly restores the degree of freedom of angular displacement, and the user can rotate the rocker arm (30) clockwise. With the rocker arm away from the closed position, the base (15) can be in the state of the tenth or the ninth.

Referring to the second to fifth figures, the two plate abutting members (60) (70) are both left and right symmetrical configurations, and the first abutting member (60) has two bodies (62) and laterally connected to the two pieces. One of the bottom edges of the body (64). The abutting member has an L-shaped side view, the front end of which is a pivoting end (65), and the other end has two first abutting claws (66) extending upward, and the two abutting claws (66) respectively Located on the two body (62). A soft sheath (67) is placed on each of the free ends of the abutting jaws. The pivoting end (65) of the abutting member (60) is pivotally disposed on the base (20) by a pivot pin (68) (as shown in the fourth figure); the two bodies (62) are located at an angle The base (20) has two sides.

The second abutting member (70) also has a two-piece body (72) and a plate portion (74) laterally connected to the rear edge of the two body members. The abutting member has an L-shaped side view, the top end of which is a pivoting end (75), and the other end has two second abutting claws (76) extending forwardly, respectively disposed on the two body pieces (72). )on. A soft sheath (77) is placed on each of the free ends of the abutting jaws. The abutting member (70) is angularly displaceable by pivoting the pivot rod (53) to the bottom end of the rocker arm (30), and the two body members (72) are located on two sides of the rocker arm (30). A stopper (26) is a rod that is transversely disposed at a rear end of the base (20) and located behind the second abutting member (70), and the stopper (26) is exposed at both ends Rocker arm (30) Two sides.

When the clamp (10) is in the closed position of the fifth figure, the abutting claw (66) of the first abutting member (60) is lower than the first plane (27) provided at the top end of the base (20); The abutting claw (76) of the two abutting members (70) does not extend beyond the second plane (38) provided on the front surface of the rocker arm (30); when the clamp is in the open position of the ninth figure, the two abuts The abutting claws (66) and (76) respectively protrude the first plane (27) and the second plane (38), as described in detail below.

When the clamp (10) is opened from the closed position of the second and fifth figures to the open position of the eighth and ninth views, the rocker arm (30) is pivoted with the pivot (35) as the center of rotation. The direction is swung to increase the angle between the base (20) and the rocker arm. During the angular displacement of the rocker arm (30), the pawl (43) at the bottom end will contact and push the first abutment member (60) upward. When the rocker arm (30) is swung to the open position, the first abutting member (60) is pushed by the finger (43) to be displaced upward to an upward position. In this position, the abutting member (60) The abutment claw (66) will be higher than the plane (27) of the base (20). For the second abutting member (70), during the swinging of the rocker arm (30), the bottom end of the second abutting member (70) will contact the stopping member (26) to generate an angular displacement. Since the stopper (26) is a fixed point, the greater the angle at which the rocker arm (30) is opened, the more the angular abutment of the abutting claw (76) of the abutting member (70), when the abutting member ( 70) When in the raised position, the front end of the abutment claw (76) protrudes from the plane (38) of the rocker arm (30).

When the clamp (10) is in the open position of the ninth figure, the two abutting members are positioned to abut against the plate, and a horizontal plate (180) is laid flat on the plane (27) of the base (20), and The beveled edge (182) of the sheet (180) rests on the abutment jaw (66) of the first abutment member (60) to position the sheet. Lay the standing plate (190) flat on the plane (38) of the rocker arm (30) with its beveled edge (192) against the abutment claw (76) of the second abutment (70). The upright sheet is placed and positioned.

During closing of the clamp (10) from the open position of the ninth figure to the closed position, the rocker arm (30) will stand upright such that the finger (43) leaves the first abutment (60), After the first abutting member (60) is no longer pushed by the finger (43), it will fall by gravity and be displaced downward to a lowered position, as shown in the second and fifth figures. At this time, the abutting claw (66) is low. In the plane (27) of the base (20); likewise, the second abutting member (70) is no longer in contact with the blocking member (26), and is displaced downward to a lowered position to abut the claw (76). ) no longer protrudes from the plane (38) of the rocker arm (30). In other words, when the clamp is in the closed position, the two abutments (60) (70) will automatically descend away from the two plates (180) (190) without obstructing the two bevels (182) (192). The combination. In addition, one of the first abutting members (60) is provided with a limiting slot (69), such as the second and fourth figures, which can be received by the stopping member (201) provided on one side of the base (20). The stop is used as the stop point when the abutment moves down.

Referring to the ninth figure, in the design of the present invention, when the two plates are positioned on the clamp, the ends (B) and (D) of the two oblique sides (182) (192) are located at the center of rotation of the clamp, That is, it is located on a concentric circle (C) of the pivot (35), so that after the clamp is closed, the two oblique sides (182) (192) are precisely and flushly butted. Further, as described above, when the adjusting screw (46) of the adjusting mechanism (45) is rotated, the angular position of the frame (40) can be adjusted, so that when the jig (10) is in the closed position, the assembler can Adjust the screw (46) so that the plane (38) of the rocker arm (30) is indeed perpendicular to the plane (27) of the base (20). It can be understood that the rocker arm can also be made into a one-piece without the function of adjusting the angle.

The shaft portion (94) of the cantilever (90) is fitted into the chamber (84) of the sliding seat (82); a screwing member (87) is screwed to the shaft portion (94) from the rear end of the sliding seat. The shaft portion is prevented from disengaging from the chamber (84) and is rotatable in the chamber. The first elastic member (96) and the second elastic member (97) each have a spring and a steel ball, and are respectively inserted into the two radial holes (85) and the receiving hole (86), and the first elastic One end of the member (96) is in resilient contact with the shaft portion (96). The cantilever shaft portion (94) is the center of rotation of the clamping mechanism (80), so that the user can rotate the clamping mechanism to stand the pressing rod (100) upright or turn the pressing rod (100) to one side, so that It is horizontal, as shown in the imaginary line of the eighth figure. When the pressing rod (100) is in an upright or horizontal position, each of the first elastic members (96) is engaged with a positioning portion (95), such as the thirteenth and fourteenth views, to position the pressing rod in an upright position or a horizontal position. The second elastic member (97) is elastically contacted with a guide rail (49). When the clamping mechanism (80) is moved up and down along the guide rail (49) to different heights by the elastic pressing force, the clamping mechanism can be positioned. At this height.

The buckle (110) is a hollow cylinder sleeved on the outer circumference of the cantilever (90). The two pads (115) are placed in the buckle (110) and are located on both sides of the shaft (92) of the cantilever (90). A through hole (112) runs through the top bottom surface of the buckle (110).

The upper half of the pressing rod (100) is provided with a straight groove (102) along its longitudinal direction, penetrating the front and rear end faces thereof. Referring to the fifteenth and sixteenth drawings, a mounting hole (104) and an operating hole (105) are disposed at the bottom end of the pressing rod (100), and the mounting hole (104) is located at two sides of the pressing rod; The operating hole (105) is located in the front and rear direction of the pressing rod. The two holes (104) (105) are intersected and interlocked. The pressing rod (100) penetrates the through hole (112) of the buckle (110), and the shaft (92) of the cantilever (90) also penetrates into the straight groove (102) of the pressing rod. In this way, the operator can move the pressure bar (100) up and down to different heights.

A cam member (120) is disposed in the mounting hole (104) of the pressing rod (100) and is rotatable in the mounting hole; a recess (122) is disposed on the peripheral surface of the cam member. A knob (125) is coupled to one end of the cam member for the person to rotate the cam member.

In the normal state, the pressure bar is vertically inclined by gravity, and at this time, the buckle (110) can move freely on the cantilever (90). To clamp the plate (190) to the rocker arm (30), move the buckle (110) along with the pressure bar (100) toward the plate (190). As shown in the fifth figure, the chuck (135) is brought into contact with the plate. The recess (122) of the cam member (120) is in contact with the block (130). Then, the cam member (120) is rotated through the knob (125). As shown in FIG. 17, the recess (122) is moved away from the block (130), and the peripheral surface of the cam member is pressed against the block (130). ), since the chuck (135) has been in contact with the sheet material and cannot be moved, the effect of the cam will cause the bottom end of the pressing rod (100) to be displaced to the left of the seventeenth image, resulting in inclination and inclination of the pressing rod and the buckle. The front and rear ends of the buckle (110) are respectively pressed against the top surface and the bottom surface of the cantilever (90), so that the clamping mechanism (80) cannot be slipped, and the plate body (190) can be surely clamped. . For plates of different heights (190), the user can move the carriage (82) or the pressure bar (100) up and down to adjust the height of the chuck (135).

It should be noted that, in practice, the rear end of the cantilever (90) behind the holder can be directly connected or pivoted to the rocker arm without providing the slider.

In this embodiment, the clamp (10) is assembled on the steel material. Therefore, the embodiment further includes a clamp (160) for clamping the steel and a post (140) for connecting the base (15) to the clamp. ).

Referring to the fourth, fifth and eighteenth drawings, a rear end of the post (140) is provided with a through hole (142) extending through the top surface thereof; and a bottom of the front end of the base (20) is fixed with a post (28). And the bottom end of the insertion post (28) penetrates the through hole (142) of the post (140), so that the base and the post can slide up and down relatively; an elastic component (29) is a spring, sleeved on The insertion post (28) has its two ends abutting against the base (20) and the post (140), and the effect of the base and the post being relatively elastically slidable will be described below. Referring to the fourth figure, the post is provided with a pin (141) which can be embedded in the groove (281) of the circumferential surface of the post (28). On the one hand, the post and the base do not rotate relative to each other, and on the other hand, the second (140) (20) will not be separated. A mounting hole (144) is disposed at the rear end of the post, penetrates the two sides of the post, and communicates with the through hole (142). a recessed hole (146) recessed inwardly from the front end of the post (140); a force applying rod (148) received in the recessed hole (146) and elastically pressed by an O-ring (149) In the hole wall of the recessed hole.

a clip assembly (150), as shown in Fig. 18, is mounted in the mounting hole (144) of the post (140), and includes a knob (152) and two clips (155) (156), The two clamps are loaded into the mounting hole (144) and are displaceable within the mounting hole. The two clamping blocks (155) (156) are each provided with a screw hole (157) (158) penetrating the end surface thereof, and the spiral directions of the two screw holes are opposite. In addition, an inner side surface of the two clamping blocks (155) (156) is provided with an oblique clamping surface (1551) (1561), and each clamping surface may be a flat surface or a curved surface. The two clamping faces (1551) (1561) respectively contact the circumferential faces of the two sides of the insertion post (28). The knob (152) has a screw portion (153) and is screwed to the screw hole (157) (158) of the two clamping blocks (155) (156) by the screw portion (153). When the knob (152) is rotated in one direction, for example, clockwise, the two clamps (155) (156) can be moved closer to each other and pressed to the circumferential surface of the insertion post (28). Thus, the two clamps The inner wall of the through hole (142) is formed by three-point clamping, and the post (28) is tightly clamped so that the base (20) and the post (140) cannot move relative to each other. When the knob (152) is turned in the other direction, the two clamping blocks (155) (156) can be moved away from each other, and the insertion post (28) is no longer clamped, and the base and the post can be relatively displaced.

It can be understood that the through hole (142) and the clip assembly (150) can be disposed on the base (20), and the bottom end of the post (28) is fixed to the post (140). In this way, the post penetrates the base into the base, and the base can still slide up and down relative to the post and clamp the post with the clamp assembly.

Referring to Figures 19 to 21, the holder (160) comprises: a body (161), the upper half of which is a hollow cylindrical portion (162), and the outer peripheral surface is provided with a thread; and the lower half A leg portion (163) is formed on each of the two sides, so that the lower half of the body (161) is connected front and rear. A first clamping mechanism is formed on the upper half of the holder, and includes a top plate (164), a clip (168) and a rotating ring (165). The top plate (164) is screwed or fixed to the top end of the body (161); the rotating ring (165) is screwed to the cylindrical portion (162) with its screw hole (166), and is located at the top plate ( 164), the circumferential surface of the swivel is provided with a plurality of insertion holes (167) at equal intervals; the clip (168) is sleeved on the outer circumference of the body (161) with its through hole (169), and can be on the body Sliding and rotating, and located between the top plate (164) and the rotating ring (165). A second clamping mechanism is formed on the lower half of the holder, and includes a clamping member (170) and a cam trigger (176). The clamping member (170) has a front and rear through hole (172); an adjusting ring (174) is screwed to the screw portion (173) at the bottom end of the clamping member. The clamping member (170) and the adjusting ring (174) are inserted into the body (161) to slide in the body. The perforations (172) of the jaws (170) are directed to the void of the body (161). The cam lever (176) has a cam portion (177) pivotally connected to the bottom end of the two legs (163) of the body, the cam portion contacting the bottom end of the clamping member (170) . When the adjusting ring (174) is rotated, the height formed by the clamping member (170) and the adjusting ring (174) can be changed to adjust the height at which the through hole (172) is located.

When the cam lever (176) is in the release position of the twentieth and twenty-first figures, the cam portion (177) does not contact the clamp member (170) (or the adjustment ring (174) at the most convex position. At this time, the through hole (172) of the clamping member has a large gap with the bottom surface of the rotating ring (165), and the connecting rod (140) can be inserted into the through hole (172). To make the clamping seat (160) When the lever (140) is clamped, when the lever (176) is pulled to the latch position of the twenty-second figure, the cam portion (177) contacts the clamping member (170) at the most convex position. (or adjusting the ring), and then pushing the clamping member upwards, so that the distance between the perforation (172) and the rotating ring (165) is shortened, so that the bottom edge of the through hole (172) and the bottom surface of the rotating ring (165) are clamped to the post ( 140). Pulling the lever (176) back to the release position of the twentieth diagram allows the jaws (170) to be moved down so that the posts (140) are no longer pinched by the holder (160) and can be removed. Thereby, the holder can quickly clamp or release the post. It can be understood that if the height of the swivel (165) is reduced so that the bottom surface is higher than the bottom edge of the tubular portion (162), the bottom edge of the perforation (172) and the bottom edge of the tubular portion (162) are used. Clamp the post.

Referring to the twenty-third figure, the first clamping mechanism of the holder (160) is used to clamp a C-shaped steel (210), and the second bottom wall (212) of the C-shaped steel is moved into the top plate (164).
