Description

Technical Field

[0001] The utility model relates to the technical field of brake disc grinding devices, in particular to a vehicle brake disc grinding device. Background Art

[0002] The brake disc is a round plate that rotates when the car is moving. The brake caliper clamps the brake disc to generate braking force. The brake disc will have unevenness such as wear, burrs, scratches or grooves during use. These unevenness will affect the tacit understanding between the brake pad and the brake disc, so the brake disc grinding device came into being.

[0003] When the brake disc grinding device is in use, the brake disc is clamped by the clamping device to a position that fits the grinding assembly, and the grinding assembly and the brake disc rotate simultaneously to achieve the purpose of grinding and smoothing the edge of the brake disc. During the grinding process, the temperature at the friction point is too high, and the generated debris splashes, which not only poses a risk of injuring the user, but also the debris will adhere to the splashing point after cooling, making it inconvenient to clean. Therefore, a vehicle brake disc grinding device is proposed to address the above problems. Utility Model Content
