Description

Anti-twist tooling and tightening mechanism

technical field

The utility model relates to the technical field of installation and maintenance tools, in particular to an anti-torsion tooling and a tightening mechanism.

Background technique

In the production and manufacture of vehicles, there are often many installation processes that require the bolts to be locked or loosened by tightening devices. For example, when assembling the front strut and the body, it is usually necessary to use electric tightening tools to tighten the springs above the shock absorbers. The three bolted connection points on the seat are bolted.

On the premise, when the locking sleeve 3 is locked corresponding to different first bolts, the swing arm 4 can drive the reaction sleeve assembly 5 to rotate around the positioning shaft 6 to adjust the matching second bolts, ensuring that The reaction force sleeve assembly 5 remains stationary when the locking sleeve 3 locks the first bolt, so as to offset the locking reaction force of the first bolt, prevent the locking tool from shaking, and prevent the operator from fatigue injury or falling off the platform .

12, the first bolt and the second bolt in this embodiment are two of the three bolts a, b, and c that are evenly distributed on the top of the front strut. Between the bolts is the spring support d of the shock absorber, the bolt that needs to be locked is the first bolt, and the bolt that has been locked or waiting to be locked is the second bolt, for example: when bolt a needs to be locked When the bolt a is tightened, the first bolt is to be matched with the locking sleeve 3, and the bolt b or bolt c is used as the second bolt and needs to be matched with the reaction sleeve assembly 5; further, this embodiment provides The anti-twist tooling is not only suitable for the installation process of the front strut and the body, but also for the locking operation with at least two bolts; wherein, the distance between adjacent bolts determines the length of the rotating arm 4, and then the rotating arm The length of 4 can be designed and adjusted according to the actual function of the bolt, so I won't go into details here.

Of course, the rotation stop angle of the rotating arm 4 can also be set to other angles) on either side of the locking sleeve 3. One side (that is, the left or right side in the figure) remains stationary, that is, the reaction force sleeve assembly 5 can rotate 180 degrees around the positioning axis 6 and rotate the locking sleeve 3 along the second direction. There are two stationary work positions on both sides of the device, referring to Figure 11, the operator's work position is in the lower right of the figure and always unchanged (in actual operation, refer to the lower left position of Figure 12 for the operator's work position), at this time, when the second bolt is in the clockwise relative position of the first bolt (the locking sleeve 3 in the figure) in FIG. 11 , the reaction sleeve assembly 5 should be located in the On the right side of the locking sleeve 3 in Fig. 11 (that is, the position currently shown in Fig. 11 ), when the second bolt is in the counterclockwise relative position of the first bolt in Fig. 11, the reaction force sleeve assembly 5 should be located on the left side of the locking sleeve 3 in FIG. 11 , and the change of the above two working positions requires the active drive of the rotating arm 4 to drive the reaction sleeve assembly 3 to change the working position.

According to the above list, the locking sleeve 3 is arranged on the base frame 2 in this application document, and the automatic locking of the first bolt is realized by the electric control of the locking tool 7, and at the same time on the base frame 2 by the rotating arm 4.

Further, referring to FIG. 2 , FIG. 3 and FIG. 10 , in the anti-torsion tooling 1 provided by the embodiment of the present invention, in a specific implementation, the reaction force sleeve assembly 5 includes a reaction force sleeve 51 , a ratchet head 52 and the fixed part 53;

The reaction force sleeve 51 is disposed at the end of the rotating arm 4 away from the positioning shaft 6 and the reaction force sleeve 51 and the locking sleeve 3 extend in the same direction, and the reaction force sleeve 51 is far away from the positioning shaft 6 . One end of the rotating arm 4 is matched with the second bolt;

The driving end 521 of the ratchet head 52 is rotatably connected with the positioning shaft 6 , and the connecting end 522 of the ratchet head 52 is connected with the fixing portion 53 parallel to the rotating arm 4 ;

A side of the fixing portion 53 facing the rotating arm 4 is provided with an accommodating groove 531 , and the accommodating groove 531 is adapted to the rotating arm 4 .

Specifically, in order to realize that the reaction force sleeve assembly 5 can remain stationary in two working positions during the rotation process, in this embodiment, the reaction force sleeve assembly 5 is set to be supported by the reaction force sleeve The cylinder 51, the ratchet head 52 and the fixing part 53 are composed; wherein, the reaction force sleeve 51 is a hollow or partially hollow (at least one end away from the rotating arm 4) cylindrical structure, and can further It is sleeved outside the second bolt and cooperates with the second bolt to form a fixed point; wherein, the ratchet head 52 is a bidirectional ratchet head, which can be controlled by a switch to realize forward and reverse rotation and cannot be rotated in a certain direction. Reverse rotation occurs, the above features are well known to those skilled in the art for the bidirectional ratchet head 52, and will not be repeated here, for example: referring to FIG. downward and always unchanged, at this time, when the second bolt is in the clockwise relative position of the first bolt in the figure (that is, the locking sleeve 3 in the figure), the reaction force sleeve assembly 5 should be located on the right side of the locking sleeve 3 in the figure (that is, the current display in the figure), when the second bolt is in the counterclockwise relative position of the first bolt in the figure, the reaction sleeve The barrel assembly 5 should be located on the left side of the locking sleeve 3 in the figure, then the ratchet head 52 is controlled to rotate clockwise in the figure, and the above-mentioned rotating arm 4 can drive the reaction force sleeve The cylinder assembly 5 is rotated to the left side of the locking sleeve 3 described in the figure, and vice versa, and will not be repeated here; the driving end 521 of the ratchet head 52 is rotatably connected with the positioning shaft 6, thereby realizing When the rotating arm 4 is manually rotated clockwise or counterclockwise around the positioning shaft 6, the ratchet head 52 can lock the rotating arm 4 in the rotating direction to prevent it from rotating in the opposite direction, that is, referring to the accompanying drawings 11. When the rotating arm 4 rotates clockwise from the position in the figure, the characteristic of the ratchet head 52 enables the rotating arm 4 to rotate only in the clockwise direction, but cannot rotate in the opposite direction, which ensures the stability of the rotating arm 4. When the rotating arm 4 drives the reaction sleeve 51 from the position on the left side of the locking sleeve 3 to rotate counterclockwise to the position shown in the figure, it is necessary to first control the ratchet head 52 to reverse Rotate in the direction of rotation, and then repeat the above rotation process.

After the position is stopped, the fixed portion 53 cannot move in the opposite direction, and the accommodating groove 531 also ensures that the rotating arm is bound to remain in the accommodating groove 531, and cannot be in the accommodating groove 531. Clockwise or counterclockwise opposite movement or movement trend; further, when the rotating arm 4 rotates to a position that interferes with the stop portion 91 of the limiting member 9, the fixing portion 53 and the above-mentioned The limiting member 9 also ensures that the rotating arm 4 cannot move or move in a fixed working position.

A shaft sleeve 41 and a second shaft sleeve 42 , the first shaft sleeve 41 is sleeved outside the positioning shaft 6 , so that the rotating arm 4 can rotate around the positioning shaft 6 .

Specifically, referring to FIG. 2 , FIG. 9 and FIG. 11 , in order to realize the situation that the anti-twist tooling 1 will move in the direction of the bolt as a whole when the locking sleeve 3 locks the first bolt, in this embodiment The reaction sleeve 51 has a first segment 511 and a second segment 512 connected in sequence along its extending direction (the second segment 512 of the first segment 511 and the second segment 512 must be hollow It is not too limited whether the first section 511 is hollow or not. If it is necessary to reduce the quality of the overall anti-torsion tooling 1, it should be made hollow. If the strength of the reaction sleeve 51 is enhanced, avoid the If it deforms or breaks when counteracting the reaction force, it can be made non-hollow); the first section 511 is connected to the end cover 10 through the second bushing 42, and the first section 511 in this embodiment is here. The end cover 10 is connected with the end cover 10 by bolts. The diameter of the end cover 10 is larger than the diameter of the second bushing 42. The first section 511 is connected with a spring 11. The end of the second shaft sleeve 42 facing the second section 512 is in conflict with the end of the second section 512 facing the second shaft sleeve 42 ; the outer diameter of the first section 511 is smaller than the second shaft The inner diameter of the sleeve 42, the inner diameter of the second shaft sleeve 42 is smaller than the outer diameter of the second section 512; with reference to FIG. 11, the above design can make the entire The anti-twist tooling 1 moves to the lower left in the figure.

At the same time, after the locking operation is completed, the reaction force sleeve 51 is locked in the spring 11. Under the action of moving to the lower left in the figure, since the diameter of the end cover 10 is larger than the inner diameter of the second bushing 42, the reaction sleeve 51 will not come out of the second bushing 42, which can not only Matching with the position change of the locking sleeve 3 ensures the balance of the overall anti-torsion tooling 1 and does not require human intervention during the working process, which greatly enhances the practicability.
