Abstract
This utility model discloses a puller for broken tap, with a purpose of providing a puller for broken tap with simple structure, easy manufacturing and convenient use. The puller comprises claws, a body and a retaining end, wherein the claw is arranged at the bottom of the body in a circular direction, the quantity and the shape of the claws shall be the same as those of chip flutes of the broken tap, the outer diameter of the circle surrounded by all claws shall be less than that of the broken tap. The retaining end can be a tetrahedron, a pentagon, a hexagon or other shapes. The utility model is applicable to pulling broken taps during automobile assembly, installation and commissioning or maintenance.
Description
Technical field
The utility model relates to auto assembly, debugs and flight-line maintenance, is specifically related to a kind of fracture of wire awl take-off device.
Background technology
In the auto assembly process, during the welding projection welding nut, the silk tooth of project-welding nut partly is easy to be out of shape because of formation crator, welding slag.When with screw tap the silk tooth of project-welding nut being carried out clearly silk, the existence because of crator, welding slag is easy to cause screw tap to fracture again.After screw tap fractureed in the past, all be that the iron sheet at project-welding nut place " is windowed ", the project-welding nut that will cause screw tap to fracture shovels, and the new project-welding nut of burn-oning will " be windowed " and be located to weld, and not only labour intensity is big, inefficiency, and influence vehicle product quality.
Summary of the invention
For overcoming the problem that prior art exists, the utility model provides a kind of fracture of wire awl take-off device, the screw tap that fractures can be taken out smoothly, the iron sheet at project-welding nut place " is windowed " the new project-welding nut of burn-oning after having avoided screw tap to fracture.
Fracture of wire awl take-off device scheme of the present utility model is as follows:
Fracture of wire of the present utility model awl take-off device has a shaft-like body, and the body top is a bare terminal end, is used for and is connected fast joint such as pneumtic impact wrench, is convenient to pincerlike tool operation simultaneously.The bottom of body is along the circumferential claw that is furnished with, the quantity of claw is identical with the chip pocket quantity and the shape of fracture of wire awl with shape, the external diameter of the circle that all claws surround is less than the external diameter of screw tap, claw can correspondingly insert in the chip pocket of fracture of wire awl in use, by turning bare terminal end, the fracture of wire awl can be taken out by external tool.
External tool clamping for convenience, described bare terminal end adopts polygon, as four limits, five limits, six distortion or other shapes.
The beneficial effects of the utility model are: simple in structure, make easily, and easy for operation, can increase work efficiency, guarantee product quality.

Among the figure: claw 1 body 2 bare terminal ends 3
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is further described:
As shown in Figure 1, this fracture of wire awl take-off device is made of successively claw 1 body 2 and bare terminal end 3, body 2 is the shaft-like of circle, bare terminal end 3 is square above body 2, the bottom of body 2 is furnished with three claws 1 along circumferential, referring to Fig. 2 and Fig. 3, three claws 1 evenly distribute in a triangle, and the shape of claw 1 is identical with the shape of the chip pocket of fracture of wire awl, and the external diameter of the circle that all claws surround is less than the external diameter of screw tap.
Model according to the fracture of wire awl is different with shape, and this fracture of wire awl take-off device claw 1 also can be four pawls, and as Fig. 4, Fig. 5 and shown in Figure 6, body 2 is a Cylinder, and bare terminal end 3 is a square;
Certainly, body 2 also can adopt other shapes such as multiple edge body, and bare terminal end 3 also can be five limits, hexagon or other shape.
Get when pulling off screw tap, claw 1 is inserted in the fracture of wire awl groove, vise bare terminal end 3 rotations with instrument, soon the fracture of wire awl is got and is extracted.
Claims (2)
1, a kind of fracture of wire awl take-off device, it has a shaft-like body, it is characterized in that, the body top is a bare terminal end, the bottom of body is along the circumferential claw that is furnished with, the quantity of claw is identical with the chip pocket quantity and the shape of fracture of wire awl with shape, and the external diameter of the circle that all claws surround is less than the external diameter of screw tap.
2, fracture of wire awl take-off device according to claim 1 is characterized in that described bare terminal end is a polygon.
