Description

Technical Field

[0001] The utility model relates to the technical field of riveting, in particular to a universal riveting tool. Background Art

[0002] In clutch manufacturing, riveting is one of the key processes to ensure reliable connection between clutch components. With the continuous development of the automotive industry, more stringent requirements are being placed on the quality, performance, and production efficiency of clutches.

[0003] Traditional riveting tooling used in clutch production has many shortcomings. When riveting clutch parts of different models and specifications, it is often difficult to accurately position workpieces of complex shapes and various sizes due to the lack of flexibility in its positioning method. This may lead to riveting position deviations, thereby affecting the overall performance and reliability of the clutch. For example, some traditional tooling cannot effectively adapt to clutch plates, pressure plates and other components with special geometric shapes or non-standard sizes, increasing the defective rate.

[0004] Therefore, we propose a universal riveting tool to solve the above problems. Utility Model Content
