Detection tool for detecting runout and perpendicularity of brake assembly

Abstract

The invention discloses a detection tool for detecting the runout and the perpendicularity of a brake assembly. The detection tool comprises a detection tool base (1), a detection component seating portion, and a measuring mechanism. The detection component seating portion and the measuring mechanism are both arranged on the base. The measuring mechanism comprises a measuring table seat (31) arranged on the detection tool base (1); a supporting rod (32) arranged on the measuring table seat (31); and two brackets (33) slidably arranged along an axial direction of the supporting rod (32). A dialindicator (4) is arranged on any of the brackets (33). Each dial indicator (4) can slide along the length direction of each bracket (33). The detection tool not only accurately measures the tolerances of the runout and the perpendicularity of the brake assembly, but also measures various specifications of brake assemblies.

Description

technical field [0001] The invention relates to the field of inspection tools for detecting automobile brake parts, in particular to a inspection tool for detecting the runout and verticality of a brake assembly. Background technique [0002] In the processing of automotive brake parts, not only high dimensional accuracy is required, but also strict requirements for shape tolerance and surface roughness. The purpose of the above requirements is: on the one hand, to ensure the safety and stability of the brake during operation, on the other hand, it is beneficial to prolong the service life of the brake, and at the same time reduce the probability of brake failure. Once unqualified products need to be reprocessed or become waste products, the role of inspection tools is very important. [0003] In the traditional technology, the verticality measurement mostly uses the method of hammer thallium hanging wire to visually measure the verticality of the brake assembly. This metho...

Problems solved by technology

[0003] In the traditional technology, the verticality measurement mostly uses the method of hammer thallium hanging wire to visually measure the verticality of the brake assembly. This method is too subjective, and it is difficult to accurately determine whether the verticality meets the requirements; The table slides from a lifting base from top to bottom to test the verticality tolerance. Although some progress has been made, there are still errors in the results due to the unstable control of the sliding speed during the test, and the more unstable the sliding speed, the greater the error

For the runout measurement, the setting of the detection part placement part in the prior art is too simple, such as: large friction or no parts to reduce the error, etc. are often the cause of the error
