Abstract
The invention discloses a shank connecting drill and a manufacturing method of the shank connecting drill, and aims at providing a shank connecting drill with a simple structure, convenience in use and low machining cost, and a manufacturing method of the shank connecting drill. The shank connecting drill comprises a drill rod. The front end of the drill rod is a cutting edge, a spiral chip groove is arranged on the drill rod, and the tail end of the drill rod is connected with a drill shank for clamping. The shank connecting drill is characterized in that the drill rod and the drill shank are separated, a hole matched with the tail end of the drill rod is arranged at one end of the drill shank, the tail end of the drill rod is connected in the hole of the drill shank in a plugging manner, and the drill rod and the drill shank are fixedly connected into a whole. The drill rod and the drill shank is fixedly completed integrally as follows: the edge of the hole is extruded to narrow the hole, so that the drill shank tightly grips the tail end of the drill rod, and the relative rotation between the drill rod and the drill shank can not occur. The shank connecting drill has the advantages that the connection is reliable, the material consumption is few, the manufacturing is convenient, different materials are selected for the drill rod and the drill shank according to respective requirement, the economy is good, the cost is low, and the subsequent processing can not be affected.
Description
Technical field
The invention belongs to the instrument of machining hole, particularly boring drill bit, the handle that connects that especially differs bigger for drilling rod and drillstock diameter dimension bores and manufacturing approach.
Background technology
The drill bits of using for the boring carpenter of carpenter, mechanic such as fluted drill; It is very little of the 1-3 millimeter in use to run into the hole of need boring through regular meeting, and common drill bit drilling rod is identical with the drillstock diameter dimension often, this is for drill bit that just can't these tiny diameters of clamping than the drilling machine of specification greatly; Must change on the little beakiron and process; Cumbersome, thus the drill bit of a kind of reducing of manufacturers design, the specification manufacturing of pressing drill bit at the drilling rod place; And be used for the drillstock place overstriking of clamping drilling bit, form step.When making this drill bit; Adopt the thick bar processing of processing drillstock, a large amount of cut to the tiny drilling rod size of process at the drilling rod place, consuming time, the consumptive material of such method; Stock utilization is low; Manufacturing cost is high, and is very uneconomical, sometimes also since the thickness of drilling rod and drillstock than too big problems such as quenching degree when causing the concentrated or heat treatment of stress.
Summary of the invention
The purpose of this invention is to provide a kind of handle that connects simple in structure, easily manufactured, that processing cost is low bores and manufacturing approach.
In order to reach above-mentioned requirements, the present invention realizes through following technical scheme: it includes drilling rod, and the front end of drilling rod is a cutting edge; Be shaped on spiral chip area on the drilling rod; Be connected with the drillstock that supplies clamping at the tail end of drilling rod, it is characterized in that described drilling rod and drillstock are splits, be shaped on the hole that matches with the drilling rod tail end at an end of drillstock; The drilling rod tail end is plugged in the hole of drillstock, and drilling rod and drillstock are fixedly fused.
Described hole is a circular hole.
Described drillstock is six prisms or cylindrical.The surface of said six prismatic drillstocks is shaped on the arc-shaped groove of ring-type.
It is through the extruded hole outer rim that described drilling rod and drillstock fixedly fuse, the distortion that lets the hole dwindle, and make drillstock embrace the drilling rod tail end tightly, and relative rotation does not take place.
Described extruding is to push to the center in hole in the direction that circumferentially is uniformly distributed with through at least three in the outer rim in hole.
Described at least three directions extruding is three or four or six direction extruding.
Connect the handle brill and connect the handle brill with this scheme manufacturing with the method manufacturing; Have connect reliable, consumptive material is few, convenient processing and manufacture can be according to the different material of requirement selection separately for drilling rod and drillstock; Good economy performance, cost are low, following process are not had the advantage of influence.

The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the present invention is done further description.
Fig. 1 connects the structural representation that handle bores.From figure, find out; It includes drilling rod as shown in Figure 21; The front end of drilling rod 1 is a cutting edge 2, is shaped on spiral chip area 3 on the drilling rod 1, is connected with the drillstock 4 of confession clamping at the tail end of drilling rod 1; Described drillstock 4 is a hexagon, and the arc-shaped groove 5 that is shaped on ring-type on the surface of six prismatic drillstocks 4 is like Fig. 3, shown in Figure 4.Drillstock 4 is also columniform.Described drilling rod 1 is splits with drillstock 4, promptly is not one manufacturing, is shaped on the hole 7 that matches with drilling rod tail end 6 at an end of drillstock 4; Drilling rod tail end 6 is plugged in the hole 7 of drillstock 4; Pass through extruded hole 7 outer rims again, the distortion that lets hole 7 dwindle, and make drillstock 4 embrace drilling rod tail end 6 tightly; And relative rotation does not take place, drilling rod 1 and drillstock 4 are fixedly fused.Described hole 7 is a circular hole.Described extruding be in the hole 7 outer rim through at least three in the direction that circumferentially is uniformly distributed with to the extruding of the center in hole 7.As shown in Figure 5 is three direction extruding; As shown in Figure 6 is that six direction pushes.Above-mentioned drillstock 4 be shaped as six prisms, drillstock 4 can be processed the cylindrical of common fluted drill as required, the forms such as four direction extruding that extruding can be as shown in Figure 7.Form and several direction of extrusion for drillstock 4 are no longer carefully stated.
The above is specific embodiment of the present invention and the know-why used, if the change of doing according to conception of the present invention, when the function that it produced does not exceed spiritual that specification contains yet, still belongs to protection scope of the present invention.
