AI Technical Summary
In the existing technology, the double hinge shaft riveting of car seat brackets has problems such as poor coaxiality and low riveting efficiency. Traditional methods are difficult to control the riveting force and displacement accurately, resulting in poor product stability and consistency, long production cycle and high product scrap rate.
A synchronous riveting device for dual hinge shafts of an automotive seat bracket is adopted. It utilizes a pneumatic positioning fixture and a servo motor-driven riveting unit to achieve synchronous riveting of dual hinge shafts. The device prevents bending of the hinge shafts through contour positioning and elastic connecting support blocks, ensuring the coaxiality of the hinge shafts and the quality of the riveting.
It achieves coaxiality consistency of the dual hinge shafts and improves riveting efficiency, reduces product scrap, improves riveting quality and production efficiency, and simplifies the debugging and production process.
