Abstract

The invention relates to a blind hole workpiece dismounting device, and belongs to the field of mechanical machining. According to technical scheme, the blind hole workpiece dismounting device comprises a force transmission rod; a press-fit top plate is arranged at the top of the force transmission rod; a self-centering conversion chuck is arranged at the bottom of the force transmission rod; a compression rod head or a pull rod head is arranged on the self-centering conversion chuck; and the compression rod head extrudes a shaft workpiece in a blind hole in a blind hole workpiece or the pullrod head pulls up after the pull rod head is fixed with a broken piece in the blind hole. The blind hole workpiece can be mounted more accurately, can be dismounted more conveniently and quickly without damage, and the labor intensity of workers can be greatly reduced.

Description

technical field [0001] The invention relates to a blind hole workpiece dismounting device, which belongs to the field of mechanical processing. Background technique [0002] In the machining process, the machining of blind hole workpieces is very common machining. The common method is to impact the shaft with a hand hammer. Under the action of the impact force, the shaft will slowly move down until the shaft is in place. It is more difficult to disassemble the blind hole workpiece. It is necessary to weld an easily disassembled workpiece on the broken part with an electric welding machine, and then disassemble the combined workpiece with tools. The diameter of some blind hole workpieces is relatively small, and the broken part cannot be taken out if the broken part is not exposed outside the blind hole, so the workpiece can only be billed. [0003] At present, the installation of blind holes is laborious with a hand hammer, not to mention that it is easy to damage the shaft...
