Abstract
The utility model belongs to mechanical frock clamp art, be specifically related to a kind of alignment pin extractor, comprise gripper shoe, screw shell and bolt, described screw shell extends through gripper shoe, screw shell is provided with screw thread in gripper shoe, gripper shoe side has the clearance plane leading to thread bush, and in gripper shoe, face, down suction is provided with screwed hole, and bolt is arranged on screwed hole through clearance plane.Solve alignment pin and exit difficulty, the problem that general frock tool cannot carry out disassembling, complicated operation and the alignment pin exited also cannot reuse, the utility model to exit this type of alignment pin not with exiting screw thread within a short period of time, recycling and do not damage other accessory of motor.
Description
Technical field
The utility model relates to mechanical frock clamp art, particularly a kind of alignment pin extractor.
Background technology
The free degree acting as restricted part assembling parts of alignment pin, alignment pin all adopted interference fit with accessory.Alignment pin divides cylindrical positioning pins, circular cone alignment pin and elastic positioning pin, small part cylindrical positioning pins and circular cone alignment pin are with exiting screw thread, but most of straight pin, taper bolt, groove pin are not with to exit screw thread, elastic cylinder alignment pin is not with to exit screw thread.This type of accessory not with exiting screw thread is being disassembled in process, and spare and accessory parts need to use particular form to carry out destructiveness and disassemble, and alignment pin can not reuse, and other accessory also may be caused to damage.
Disassembling in motor process, this type of alignment pin exits very difficult, and general frock tool cannot be disassembled at all.Exit this type of alignment pin many employings welding nut in practice, then exited with Special pin puller, but so not only complicated operation and the alignment pin exited also cannot reuse.
Utility model content
The utility model object is to design a kind of alignment pin extractor, solves the problems of the technologies described above, is realized by following technical characteristic:
A kind of alignment pin extractor, comprise gripper shoe, screw shell and bolt, the through gripper shoe upper and lower surface of described screw shell, screw shell is divided into screw thread in gripper shoe inside, gripper shoe side has the clearance plane leading to thread bush, on gripper shoe opposite side, face, down suction is provided with screwed hole, and bolt is arranged on screwed hole through clearance plane.
Further, gripper shoe is separately provided with a hole, clearance plane is extended on hole by screw shell.
Further, bolt head lower end is provided with plain washer.
Further, bolt is M12 bolt.
Beneficial effect: a kind of alignment pin extractor of the utility model, can exit this type of alignment pin not with exiting screw thread within a short period of time, recycling and do not damage other accessory of motor.

In accompanying drawing, mark represents: 1, bolt 2, plain washer 3, gripper shoe 4, screw shell 5, clearance plane 6, hole.
Detailed description of the invention
Embodiment 1
A kind of alignment pin extractor, comprise gripper shoe 3, screw shell 4 and M12 hex bolts 1, described screw shell 4 extends through gripper shoe 3, screw shell 4 is provided with screw thread in gripper shoe 3, gripper shoe 3 side has the clearance plane 5 leading to thread bush 4, in gripper shoe 3, face, down suction 5 is provided with screwed hole, and bolt 1 is arranged on screwed hole through clearance plane 5.Bolt 1 head lower end is provided with plain washer 2.
Embodiment 2
Major part is identical with embodiment 1, and difference is: in gripper shoe 3, be separately provided with a hole 6, clearance plane 5 is extended on hole 6 by screw shell 4.The effect increasing hole 6 makes the utility model gripper shoe 3 elastic deformation under the effect of bolt 1 increase, and clamping force increases.
During use, alignment pin extractor is arranged on and needs on the alignment pin extracted, the gripper shoe 3 of alignment pin extractor is adjacent to seize locating surface, alignment pin is aimed at screw shell 4 center, tighten with the bolt 1 of hexagon bolt wrench by M12, clearance plane acts on due to bolt 1, the clamping and positioning that narrows gradually pin.The pin removal matched with alignment pin interface size is screwed in screw shell, relies on gravity to move around pin removal until alignment pin is extracted.
