Description

Technical Field

[0001] The utility model relates to the technical field of four-jaw chucks for lathes, in particular to a movable four-jaw chuck structure for lathes. Background Art

[0002] The full name of the four-jaw single-action chuck is the manual four-jaw single-action chuck for machine tools. It is composed of a chuck body, four lead screws, and a pair of jaws. When working, the four jaws are driven by four lead screws respectively. Therefore, the common four-jaw single-action chuck does not have the function of automatic centering. In the lathe field, the workpiece is often clamped and fixed by the chuck to facilitate the subsequent processing of the workpiece.

[0003] The debris generated by the chuck in the prior art when processing the workpiece will fall on the surface of the screw, hindering the movement of the clamping jaws. The splashing of debris is not conducive to subsequent cleaning, which degrades the environment around the lathe. The exhaust gas and dust generated around the chuck when processing the workpiece will not only pollute the environment, but also be inhaled by surrounding people, endangering their health.
