Description

Technical Field

[0001] This utility model relates to the field of automotive parts processing technology, specifically to an automotive parts positioning fixture. Background Technology

[0002] Automotive brake pads are friction materials fixed on brake drums or brake discs that rotate with the wheels. The friction linings and friction blocks bear external pressure and generate friction to achieve the purpose of vehicle deceleration. Brake pads need to be installed on specific components to cooperate with the brake wheel in order to achieve the deceleration effect. Therefore, during the manufacturing process, it is necessary to use a special drilling device to drill holes in the relevant positions of the automotive brake pads.
