Description

Technical Field

[0001] The invention relates to the technical field of parts grinding, in particular to a brake pad burr grinding device. Background Art

[0002] Abrasives and grinding tools are the general term for abrasives and grinding tools, including abrasive products and grinding tool products. Abrasives and grinding tools are known as the teeth of industry. Abrasives or grinding tools are often used as grinding tools to machine the parts to be processed to meet certain technical requirements. Commonly used abrasives and grinding tools include cutting discs and grinding wheels, shutter discs, quick-change grinding discs, grinding rolls, bonded grinding wheels, flap grinding rings and sandpaper grinding rings, non-bonded flap grinding wheels, flap grinding wheels, sandpaper rolls and velvet rolls and tungsten steel rotary files.

[0003] The deburring of automobile brake pads is a kind of abrasive grinding tools, and the general deburring of brake pads is performed by hand-held grinders or simple devices. Although the cost is low, when grinding the brake pads, the brake pads themselves are often worn out due to excessive force, resulting in the scrapping of the brake pads and unnecessary economic losses. In addition, the general grinding device can only grind one type of brake pad, and the grinding efficiency is low. For this reason, we propose a brake pad deburring device. Summary of the invention
