Description

Technical Field

[0001] The utility model relates to the technical field of brake calipers, in particular to a brake caliper inspection tool. Background Art

[0002] The brake caliper is a caliper device that has the function of slowing down, stopping or keeping the moving wheels stopped. It is generally used in disc brake systems. The disc brake on the car is composed of a brake oil pump, a brake disc connected to the wheel and a brake caliper on the disc. When braking, the high-pressure brake oil pushes the piston in the caliper, pressing the brake shoe against the brake disc to produce a braking effect. The caliper is equipped with a dust cover to prevent foreign particles from damaging the piston. It is also matched with shock-proof shrapnel to fix the brake pads to reduce the noise of daily use. After the caliper is processed, sampling inspection is required to see whether the quality and performance meet the standards.

[0003] In actual testing, due to the wide variety of vehicles and their different sizes, the sizes of the installed brake calipers will also be slightly different. When performing performance testing on the brake calipers, the brake calipers need to be clamped and fixed, so a device that can adapt to different size data is needed for fixing and clamping to facilitate the testing operation.
