Rear axle housing assembly housing inner cavity trimming device

Abstract

The invention discloses a rear axle housing assembly housing inner cavity trimming device. The device solves the problems that the efficiency of polishing burrs at the root of a threaded hole of an existing shell inner cavity is low, and potential safety hazards are likely to be caused. The device comprises a machine frame, a positioning and clamping unit assembled on the machine frame and used for fastening a rear axle housing assembly, a trimming unit and a corresponding control loop pre-edited according to a common program, wherein the rear axle housing assembly is positioned and fastened through the positioning and clamping unit composed of a side positioning plate, a side pushing air cylinder, a rotary telescopic air cylinder and a hollow positioning table, the trimming unit formed by assembling a vertical moving mechanism, a transverse moving mechanism, a longitudinal moving mechanism and a cleaning tool with cutters into a whole is utilized, the cutters of the cleaning tool are adjusted to move to the positions above the threaded holes of the inner cavity of the axle housing in sequence, and burrs are trimmed through the cutters. The trimming device is reasonable in structural design, safe and rapid in trimming operation and capable of improving the threaded hole root burr polishing operation efficiency, optimizing the working environment and remarkably improving the rear drive axle operation quality.

Description

technical field [0001] The invention relates to a special trimming device for removing burrs at the root of the threaded hole in the inner cavity of the rear axle housing assembly, in particular to a trimming device for the inner cavity of the rear axle housing assembly instead of manual operation, which belongs to the technical field of mechanical processing and manufacturing . Background technique [0002] In order to install the main reducer in the inner cavity of the rear axle housing assembly of the rear drive axle of the automobile, it is necessary to process several threaded through holes for stud bolt connection on the housing reinforcement ring. After drilling and tapping the outer surface of the reinforcement ring, burrs generally remain at the root of the threaded hole in the inner cavity of the shell. [0003] In the existing mechanical processing and repairing technology, there is no trimming device for removing the burr at the root of the threaded hole in the ...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a rear axle housing assembly casing inner cavity trimming device, which solves the problems of low efficiency of grinding the burr at the root of the threaded hole in the existing casing inner cavity, and easily causes safety hazards. Its structural design is reasonable and the trimming operation is safe. , fast, can speed up the efficiency of grinding the burr at the root of the threaded hole, optimize the working environment, and significantly improve the running quality of the rear drive axle
