1 Internal structure diagram of lathe chuck

Lathe power chuck is mainly composed of shell, wedge main claw, wedge pull ring, pull rod nut and so on. The pull rod nut is linked to the pull rod, the other end of the pull rod is linked to the rotary oil cylinder, the oil cylinder pulls the pull rod to move, the pull rod moves with the wedge pull ring, the wedge pull ring moves up and down with the wedge main claw, and finally the clamping or loosening of the workpiece is realized.
