Description

Technical Field

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

[0002] Locomotive brakes are a braking technology used to slow or stop a locomotive during travel. In a locomotive disc brake system, the disc brakes on a locomotive consist of a brake oil pump, a brake disc connected to the wheel, and a brake caliper mounted on the disc. When braking, high-pressure brake oil pushes a piston in the caliper, pressing the brake shoe against the disc, producing the braking effect. During the brake disc production process, the discs are chamfered and polished.

[0003] When grinding and chamfering, the brake disc needs to be fixed to avoid the brake disc from moving during grinding and chamfering, which reduces the grinding quality. Since the models of brake discs are different and their sizes are different, the grinding wheel of the existing chamfer grinding device is generally fixed, and the grinding wheel needs to be adjusted before chamfering and grinding. In addition, the grinding wheel needs to be adjusted each time when grinding brake discs of different sizes, which increases the limitations of the use of the grinding device and cannot meet people's needs.
