Description

Technical Field

[0001] The utility model relates to the field of drilling devices, in particular to a drilling device for a clutch pressure plate. Background Art

[0002] The clutch pressure plate is an important component in the automobile clutch system. It is mainly responsible for pressing the clutch plate against the flywheel to achieve power transmission and disconnection. If the pressure plate fails, such as wear or spring failure, it will cause clutch failure, affecting gear shifting smoothness and normal driving.

[0003] By drilling holes in the pressure plate, its overall weight can be reduced, thereby reducing the clutch system's moment of inertia. This helps improve engine response and acceleration, which is especially important in sports or racing applications.

[0004] However, during the drilling process of the pressure plate, a lot of debris will be generated. These debris will splash everywhere, making it inconvenient to collect and clean them later. In addition, after the drilling is used many times, it needs to be maintained separately. The drill bit is usually installed tightly with the drilling device and is not easy to disassemble. In order to solve the above problems, the present invention proposes a drilling device for a clutch pressure plate. Utility Model Content
