AI Technical Summary
Existing CNC machine tools suffer from problems such as loose clamping and inconvenient loading and unloading operations during machining, especially under centrifugal force, which can easily lead to poor machining results.
By improving the chuck structure and using components such as limit clamps, reset spring rods, and counterweights, synchronous sliding and secondary clamping of the chucks are achieved through meshing and threaded transmission, enhancing stability and reliability, and ensuring the accuracy of loading and unloading even when the machine is stopped.
It improves the stability and reliability of CNC lathes during the machining process, avoids clamping loosening, ensures the accuracy of loading and unloading, and enhances overall functionality.
