Description

Technical Field

[0001] This utility model relates to the field of brake disc technology, specifically to a brake disc hole processing equipment. Background Technology

[0002] Brake discs are an important component of a car's braking system and are typically mounted on the wheels. When a vehicle needs to slow down or stop, the brake discs are compressed by the brake pads, generating friction that causes the wheels to rotate and converts this friction into heat, thus slowing down or stopping the vehicle.

[0003] Utility model patent CN217142406U discloses a drilling device for automotive brake discs, including a worktable, a frame, a support plate, and a clamping plate. A threaded screw is fixedly installed at both ends of a dual-shaft asynchronous motor. A nut sleeve is threaded onto the threaded screw. A first support rod and a second support rod are symmetrically rotatably mounted between the nut sleeve and the clamping plate. This utility model uses the dual-shaft asynchronous motor to drive the threaded screw to rotate, and then the nut sleeve moves with the rotation of the threaded screw. Simultaneously, the nut sleeve causes the included angle of the first and second support rods to contract, thereby pushing the clamping plate inward, reducing the distance between the two clamping plates. The brake disc to be drilled is then fixed by the two clamping plates. This facilitates the fixing of the brake disc, and during drilling, the brake disc can be positioned and pressed tightly to prevent displacement, thus improving the processing quality of the brake disc.

[0004] In the aforementioned prior art, it is inconvenient to change drill bits of different sizes as needed during the drilling of brake discs. Therefore, improvements are required. Utility Model Content
