Chamfer detection tool for brake pad steel backing and detection method of chamfer detection tool

Abstract

The invention relates to a chamfer detection tool for a brake pad steel backing and a detection method thereof, and the chamfer detection tool comprises an embedded pedestal which is matched with the shape of a friction block embedded groove, used for embedding a friction block, on the brake pad steel backing; an angle detection microscope which is used for detecting the chamfer diameter of the friction block embedding groove and comprises a convex lens with scale values and a focal length adjusting mechanism used for adjusting the focal length of the convex lens; an offset top seat which is fixedly arranged on the angle detection microscope, wherein the offset top seat and the embedded pedestal are arranged in a non-concentric mode so that the angle detection microscope can be chamfered towards the outer contour of the friction block embedded groove. A digital display caliper or visual inspection in the prior art is replaced by the structure, so that the problems of poor detection efficiency and large detection error of an existing chamfer detection tool are solved.

Description

technical field [0001] The invention relates to the technical field of brake device detection, in particular to a chamfering inspection tool for a steel back of a brake pad and a detection method thereof. Background technique [0002] At present, the braking of high-speed trains mainly relies on the mutual friction between brake pads and brake discs. As the speed of the train continues to increase, the braking load is increasing, and the requirements for the braking performance of the brake pads are also getting higher and higher. The edge of the friction block embedding groove of the existing brake pad steel back needs to be chamfered to ensure that when the friction block shakes within a preset range, the edge of the friction block embedding groove will not affect or damage the friction block. For this reason, it is necessary to set chamfers on the edge of the friction block embedding groove on the steel back of the brake pad. [0003] According to the requirements of th...
