Tool for disassembling and assembling nut of metallurgy mechanical device

The invention relates to the technical field of disassembling and assembling tools, in particular to a tool for disassembling and assembling a nut of a metallurgy mechanical device. The tool comprisesa sleeve pipe, a main shaft, a crank and the nut; a main pipe body is fixedly connected to the top end of the sleeve pipe, clamping blocks which are uniformly distributed in the axial direction are fixedly connected to the outer side wall of the top end of the main pipe body, and sliding grooves are formed in the inner wall of the main pipe body; the main shaft is slidably connected to the innerside of the main pipe body, a rotating rod is fixedly connected to the top end of the main shaft, and a clamping pipe is fixedly connected to the top end of the crank; a fixed clamping plate is fixedly connected to the inner side wall of the sleeve pipe, and a movable clamping plate is arranged at the position, symmetric with the fixing clamping plate, of the inner side wall of the sleeve pipe; and one end, close to the inner wall of the sleeve pipe, of the movable clamping plate is rotationally connected to a rotating ring, the other end of the rotating ring is fixedly connected to a screw rod, and the tail end of the screw rod penetrates out of the sleeve pipe and is fixedly connected to an adjusting knob. According to the tool for disassembling and assembling the nut of the metallurgy mechanical device, the structure is scientific, operation is labor-saving, the working efficiency can be effectively improved, and the tool has the huge economic benefits and the wide market requirements and is worthy of popularization.
