Abstract

The utility model belongs to the field of clamping device design and relates to a bush dismantling tool which is composed of a disc, a connecting rod bolt, spring pieces, a left clamping jaw, a right clamping jaw, a connecting pin and a compression nut. External threads are arranged at the top end of the connecting rod bolt. The bottom end of the connecting rod bolt is provided with a rectangular groove in the radial direction, wherein the rectangular groove is communicated in the transverse direction. The center of the rectangular groove and the connecting rod bolt are coaxial in line. A hole communicated with the rectangular groove is formed in the perpendicular direction of the rectangular groove of the connecting rod bolt. The left clamping jaw and the right clamping jaw are thin plate type parts identical in appearance. A small hook is arranged on the bottom of the left clamping jaw. A hole is formed in the top of the left clamping jaw. The connecting pin fixes the left clamping jaw and the right claming jaw on the connecting rod bolt. The spring pieces are arranged on the top face of the left clamping jaw and the top face of the right clamping jaw and fixed. A through hole is formed in the center of the disk. The external threads of the connecting rod bolt penetrate through the hole of the disk and are connected with the compression nut. Under the circumstance that a bush is not damaged, the bush dismantling tool is used for dismantling the bush conveniently, improves the efficiency of dismantling the bush and lowers the maintenance cost of clamping devices.

Description

A kind of bushing dismounting instrument
Technical field
