Abstract

The invention discloses a pin lifting device for an internal thread pin, and belongs to the technical field of dismounting tools. The pin lifting device for the internal thread pin solves the technical problem that the assembled internal thread pin is not easy to pull out. The solution is that the device comprises a rotating disc, a supporting disc and a thrust ball bearing, wherein the rotating disc is arranged above the supporting disc; the thrust ball bearing is arranged between the opposite end faces of the rotating disc and the supporting disc, and the axial direction of the rotating disc, the axial direction of the thrust ball bearing and the axial direction of the supporting disc are coaxially arranged; a connecting screw is installed in a first threaded hole of the rotating disc core, a pin pulling mold is detachably installed below the connecting screw through a first screw, a second screw is matched with an internal threaded hole formed on the internal threaded pin, and a shaft shoulder for limiting the connecting screw is arranged at the joint between the first screw and the second screw. The pin lifting device for the internal thread pin has a simple and light structure, converts the traditional pin pulling force from striking force to horizontal rotating force, and can pull out the internally threaded pin with high efficiency, labor saving and low noise.

Description

Technical field [0001] The invention belongs to the technical field of disassembly and assembly tools, and specifically relates to an internal threaded pin lifting device. Background technique [0002] In the field of mechanical assembly, the internal threaded pin relies on the striking force to enter the pin hole to cooperate with it, but when disassembling, a simple tool is often used to reverse the impact to make the internal threaded pin pulled out. Such a tool has a small reverse strike stroke and a small reverse strike force, resulting in a slow pin pulling process, a large amount of noise, and a large amount of physical effort for dismantling personnel. Summary of the invention [0003] In order to overcome the deficiencies in the prior art and solve the technical problem that the assembled internal threaded pin is not easy to be pulled out, the present invention provides an internal threaded pin lifting device [0004] The present invention is realized through the following...
