Brake drum cleaning jig

Abstract

The invention discloses a brake drum cleaning jig which comprises a central stepped shaft and a transmission rod, a rotating base is fixed to the central stepped shaft through a bearing, a hinge seat is fixed to the upper end of the rotating base, a sliding shaft is fixed to the upper end of the hinge seat, the sliding shaft is sleeved with a reset spring, the sliding shaft above the reset spring is sleeved with a sliding block, a limiting stop block is fixed to the sliding shaft above the sliding block, four clamping pieces are evenly hinged to the hinge base in the circumferential direction, the middle of the upper portion of each clamping piece is hinged to one end of a transmission rod, and the other end of each transmission rod is hinged to the sliding block. The brake drum cleaning jig can clamp brake drum workpieces with different diameters, due to the fact that hinged parts, supporting parts and clamping arm parts of the clamping pieces form a Y-shaped integrated support structure and can rotate around the hinged parts, circumferences with different diameters can be defined by the clamping arm parts, and brake drums with different diameters can be clamped.

Description

technical field [0001] The invention relates to the technical field of automobile manufacturing, in particular to a brake drum cleaning jig. Background technique [0002] The brake is a component in the braking system that is used to generate braking force that hinders the movement or movement tendency of the vehicle. Except for various slowing devices, automobile brakes are almost all friction brakes that use the friction between the fixed element and the working surface of the rotating element to generate braking torque. [0003] The friction brakes widely used in various types of automobiles can be divided into two categories: drum type and disc type according to the different rotating elements. The rotating element in the friction pair of the drum brake is the brake drum, and the inner surface of the cylinder is the working surface. [0004] In the production process of brake drums, it is necessary to clean and paint the inner and outer surfaces of brake drums. The cur...

AI Technical Summary

Problems solved by technology

[0007] The purpose of the present invention is to provide a brake drum cleaning jig, which has the advantages of clamping workpieces of different diameters and has a rotating function, and solves the problem that the current cleaning method is fixed clamping and a fixed high-pressure water gun head for cleaning, but it will There are some dead corners that cannot be completely cleaned, and the cleaning efficiency is low. During the cleaning process, the brake drum needs to be rotated and clamped stably, but the existing clamping tools cannot meet the production needs.
