[0002] Brakes, commonly known as brakes or brakes, are indispensable safety devices in various mechanical equipment, especially in the field of transportation. Its main function is to slow down, stop or keep moving parts stopped by friction. There are many types of brakes, which can be divided into two categories according to their working principles: friction and non-friction. Friction brakes, such as disc and drum types, generate braking force through the contact between friction materials and rotating elements (such as brake discs or brake drums); while non-friction brakes use magnetic powder, magnetic force or other physical effects to achieve braking, among which friction brake drums are more widely used.

[0003] In the existing brake drum processing process, the upper flat clamping is generally performed manually, and centering adjustment is required after the clamping is completed, resulting in low processing efficiency, high work intensity and low processing accuracy. Utility Model Content
