AI Technical Summary
Existing multi-station adaptive hydraulic chuck quick clamping devices cannot precisely control the rotation position during adjustment, and are prone to positional deviation due to external forces or vibrations, affecting machining accuracy and stability. Furthermore, chuck replacement is a complex operation and cannot meet the rapid changeover requirements of multi-station machining.
The linkage between the worm gear, worm wheel, transmission rod, slide bar, slider, slide bar, slider, first spring, limit block, support rod, first pressure block and second pressure block ensures the accurate positioning of the workpiece during the processing. The hydraulic cylinder drives the connecting rod and support rod to provide a stable axial or radial locking force, realizing adaptive clamping and quick change.
It achieves accurate and stable workpiece positioning during processing, shortens clamping time, improves production efficiency and equipment adaptability, adapts to multi-variety, small-batch production modes, and reduces operational complexity.
