Positioning tool for brake assembly assembling

Abstract

The invention discloses a positioning tool for brake assembly assembling. The positioning tool comprises an assembly base, wherein a positioning assembly is mounted on the assembly base; the positioning assembly comprises a positioning outer barrel, a positioning inner barrel and a plurality of supporting blocks; the positioning outer barrel is provided with a through hole for allowing the positioning inner barrel to be embedded; the positioning outer barrel is connected with the positioning inner barrel through a regulating mechanism; the regulating mechanism realizes up-down movement of thepositioning inner barrel; the supporting blocks are uniformly distributed at the outer side of the positioning outer barrel in a ring-shaped mode; and a gap for allowing a brake drum of a brake to beembedded is formed between each supporting block and the positioning outer barrel. The positioning tool disclosed by the invention has the advantages that the positioning inner barrel, the positioningouter barrel, the supporting blocks and a fixed block are matched, so that positioning on the brake drum is realized, the rest of fixed parts are not required, and the parts are conveniently mounted;and meanwhile, the regulating mechanism is matched, so that regulation on upper and lower positions of the positioning inner barrel is realized to match with positioning at different heights of positive and negative surfaces of the brake drum.

Description

technical field [0001] The invention relates to the field of auto parts processing, in particular to a positioning tool for assembling a brake assembly. Background technique [0002] Automobile brakes are the braking devices of automobiles. The brakes used in automobiles are almost all friction type, which can be divided into two categories: drum type and disc type. The rotating element in the friction pair of the drum brake is the brake drum, and its working surface is a cylindrical surface; the rotating element of the disc brake is the rotating brake disc, with the end surface as the working surface. [0003] Drum brakes use the brake transmission mechanism to make the brake shoe press the brake friction plate against the inner side of the brake drum, thereby generating braking force, decelerating the wheel or stopping within the shortest distance as required to ensure driving safety, and Ensure that the car is parked reliably and cannot slide automatically. At present, ...

Problems solved by technology

[0006] However, during the use of the above two toolings, parts need to be installed on both sides of the brake drum. Therefore, after the parts such as bolts are used to fix the front side and the corresponding parts are installed, the fixed parts need to be installed first. After the bolts and other parts are removed, the brake drum is turned over and then fixed to realize the installation of the parts on the opposite side of the brake drum. The whole process is cumbersome, inconvenient, and the work efficiency is not high.
