Description
Technical Field

Background
The brake shoe assembly is an important component of an automobile brake system, when a vehicle is braked, a brake shoe is opened by driving force, a shoe drum gap between a brake shoe friction plate and a brake drum is eliminated, and the friction force is generated by the friction between the friction plate and the inner surface of the brake drum so as to brake a wheel. The brake shoe assembly excircle runout is an important factor influencing shoe drum clearance, and as a key component in a vehicle brake, whether the excircle concentricity is consistent or not is very important to influence the braking effect. The same shoe drum gap exists on the circumference by detecting the excircle runout of the brake shoe assembly, and then the service life of the brake shoe assembly is prolonged. That is, in the conventional detection process, an operator generally performs accurate measurement by using a vernier caliper through manual detection, the measurement method is inefficient and has a great error, and as a single-point test, manual measurement as a single-point test cannot ensure the continuity of detection, that is, cannot detect the entire outer side wall surface of the brake shoe.
The conventional detection device for the excircle runout of the single-disc brake shoe assembly cannot be operated in a full-automatic mode, the full runout is divided into the radial run-out of an excircle and the verticality of a bus, and when the conventional equipment is used for detecting the single-disc brake shoe, an operator still needs to manually operate a measuring meter to measure the verticality of the bus, so that complete automation is not realized in the process. When the two single brake shoes are used for measurement, the single brake shoes are firstly used as independent bodies, and during installation, the installation positions of the single brake shoes are ensured to have no deviation, namely the excircles of the two single brake shoes to be detected are positioned in the same circumference. Secondly, the risk that the detecting head of the measuring meter collides with the single-plate brake shoe by mistake exists, if the detecting head of the measuring meter collides with the outer wall of the single-plate brake shoe, the measuring meter can be damaged, and the measuring work can be started from the beginning, so that unnecessary loss and manpower are increased. In view of the above circumstances, it is necessary to design a detection device for accurately measuring the brake shoe assembly outer circle runout.
