Abstract

The invention discloses a pin lifting device for internal threads, and belongs to the technical field of disassembly and assembly tools. The device solves the technical problem that an assembled internal threaded pin is not easy to be pulled out. The device comprises a connecting rod mechanism and a working threaded rod, wherein the connecting rod mechanism comprises a beating platform, a liftingplatform, a connecting rod and a double-head stud, the center of the beating platform and the center of the lifting platform are collinear with the axis of a supporting sleeve, connecting rod structures on the two sides of the axis direction of the supporting sleeve are symmetrically arranged, and the working threaded rod penetrates through the lifting platform and the supporting sleeve in sequence from top to bottom; a hammer or other heavy object is used for beating the upper surface of the beating platform, the upper surface of the beating platform is subjected to beating force, so that thebeating platform moves downwards, the lifting platform is moved upwards through the connecting rod mechanism, the threaded rod and the internal threaded pin to be pulled are driven upward to move bynuts, and the internal thread pin is pulled out. The device is simple and light in structure and convenient to manufacture, a traditional pin pulling force is converted into the beating force by the lifting force, and the internal threaded pin can be pulled out in a rapid and labor-saving manner.

Description

technical field [0001] The invention belongs to the technical field of assembly and disassembly tools, and in particular relates to a pin removal device for internally threaded pins. Background technique [0002] In the field of mechanical assembly, the internal thread pin enters the pin hole to cooperate with it by striking force, but a simple tool is often used to reversely strike the internal thread pin during disassembly, so that the internal thread pin can be pulled out. Due to the small reverse striking stroke and small reverse striking force of such tool, the pin pulling process is slow, produces a lot of noise, and consumes a lot of physical strength of the dismantling personnel. Contents of the invention [0003] In order to overcome the deficiencies in the prior art and solve the technical problem that the assembled inner threaded pin is not easy to be pulled out, the present invention provides an inner threaded pin lifting device. [0004] The present invention...
