Description

[0002] The brake disc is an important component in the automobile braking system and is usually made of metal. It is the middle part between the tire and the brake clamp. When the brake is pressed, the brake clamp will clamp the brake disc, generating resistance through friction to slow down or stop the vehicle. The installation of the brake disc requires drilling of connection holes, so the brake disc needs to be drilled during production.

[0003] For example, in the utility model patent with announcement number CN219358000U, a drilling device for brake disc production and processing is disclosed, including a base, a U-shaped mounting frame is arranged in the middle of the top of the base, a rotatable connecting strip is arranged at the bottom of the U-shaped mounting frame, one end of the connecting strip is slidably connected to an adjusting slider, the top of the adjusting slider is fixedly connected to an electric telescopic rod No. 1, and the output end of the electric telescopic rod No. 1 is fixedly connected to a drilling rig through the adjusting slider.
