AI Technical Summary
Existing screw-on mechanisms for cylindrical products can easily damage the surface coating of products, especially high-value products, through surface contact and sliding friction during the screw-on process.
It adopts a radial rotation clamping assembly and a positioning drive assembly, and clamps and rotates the product by means of rolling friction between the rotating shaft and the product. This is improved to line contact rolling friction, which avoids damage to the surface coating.
It effectively protects the product surface coating, reduces scratches and wear caused by friction, and ensures the stability and accuracy of the spin-on process.
