Abstract

A numerally controlled electric chuck of lathe is based on existing 4-jaw chuck. Its screw bolt has the driven gear for driving the jaw. The 4 drive gears engaged with said driven gear via intermediate gears are installed to 4 rotary shafts of 4 motors respectively. Its controller unit with controller and control panel is installed on lathe. Said 4 motors are respectively connected to relative outputs of control circuit.

Description

technical field [0001] The present invention relates to machine tool components, particularly improvements to lathe chucks. Background technique [0002] On lathes, there are two kinds of chucks used to clamp workpieces: three-jaw and four-jaw. The three-jaw chuck is equipped with three claws on the chuck body, and each claw meshes with a toothed disc with a spiral tooth groove through the teeth on the back. The three small bevel teeth mesh with each other. Turn any one of the small bevel teeth during use to drive the tooth plate to rotate, so that the three jaws advance and retreat synchronously to clamp round workpieces; the four-jaw chuck consists of a chuck body, four chucks Claws and four screw rods, the chuck body is equipped with four claws, the screw rod is set in the chuck body along the radial direction, corresponding to the position of the claws, and each claw is meshed with each screw through the teeth on the back. , turn the screw, the jaws move in the jaw chu...
