Internal Structure, Clamping Principle And Specification Of Standard Power Chuck For Lathe
Lathe power chuck has 2 jaws and 3 jaws. The wedge block structure is adopted inside. The wedge block is pulled by the pull rod inside the lathe spindle to realize the clamping of the jaws.
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.
2. Specification parameter table of lathe power chuck (some models)
Power chuck diameter from 26mm to 100mm, maximum static clamping force from 28.5 kN to 249kN, claw stroke from 5.4 to 10.6 (diameter).

4. clamping force performance curve of lathe power chuck
The clamping force of power chuck decreases with the increase of rotational speed.
