AI Technical Summary
Existing positioning fixtures have poor shape adaptability and matching when assembling and welding bicycle upper fork tubes. They also have a single clamping method, which leads to problems such as insecure clamping and eccentricity, affecting welding accuracy and finished product quality.
A bicycle fork tube clamping and positioning device was designed, including a guide rail, a support base and a clamping assembly. Through the cooperation of sliding and locking components, it can achieve flexible clamping and quick clamping of the fork tube, and adapt to bicycle fork tubes of different specifications.
It improves the adaptability and accuracy of clamping and positioning, shortens mold change time, ensures firm and reliable fixing, and enhances the stability of welding processes and the quality of finished products.
