Technical Field

[0001] This utility model relates to the field of hood hinges, specifically to a riveting fixture for hood hinge products. Background Technology

[0002] A hood hinge, also commonly known as a hinge, is a mechanical component used to connect two solid parts and allow them to rotate relative to each other. In automobiles, it specifically refers to the hinge that connects the hood to the body. Riveting fixtures are important equipment in the hood hinge manufacturing process. They ensure that two or more parts are securely connected together by rivets or other fasteners. In the production of hood hinges, riveting fixtures not only provide precise positioning and support but also ensure the stability and reliability of the riveting process.

[0003] A search revealed a riveting fixture with publication number CN220992728U, specifically disclosed for riveting a second riveted part and a first riveted part with riveting holes. The fixture includes a base and a positioning component. Two corresponding support blocks are connected to the top of the base. An adjustment component for the support blocks is provided inside the base. Fixing components are installed inside the four corners of the base. The positioning component is installed at the top of the base and located at the center point of the transverse central axis of the two support blocks. This invention, through the cooperation between the support blocks and the positioning component, enables the support blocks to support and fix the second riveted part and the first riveted part with riveting holes for riveting and fixing. This avoids insufficient support force from manual hand-held operation, which could lead to insecure riveting and improves the riveting efficiency. Simultaneously, the adjustment component allows for easy adjustment of the support block position, enabling the riveting and fixing of riveted parts of different lengths, further enhancing the practicality of the riveting fixture.

[0004] Existing riveting fixtures require manual placement of the product under the riveting head during use. After positioning, the riveting head descends to complete the riveting work. This manual positioning is not only inefficient but also unsuitable for hood hinge products with multiple riveting positions. Furthermore, the riveting fixtures in the comparative case mentioned above also lack precise positioning and methods to improve riveting efficiency. Long-term use of these fixtures will not only delay the riveting efficiency of hood hinge products but also lead to insufficient riveting accuracy due to inaccurate positioning.

[0005] Therefore, it is necessary to invent a riveting fixture for hood hinge products to solve the above problems. Utility Model Content
