Abstract

The invention relates to the field of clamps, and specifically relates to a multifunctional four-jaw chuck for a machine tool. The multifunctional four-jaw chuck comprises a clamping assembly, an adjusting assembly and a disc-type part clamping assembly, the four-jaw chuck is one of the clamps commonly used in machine tools, a traditional four-jaw chuck can only realize automatic centering or non-automatic centering of four claws, an ellipse and a rectangular disc-shaped part cannot be clamped, and the multifunctional four-jaw chuck solves the above-mentioned problems. The handle is shifted torotate an angle of one ratchet tooth and limits, at this time, rotating the handle can simultaneously adjust the four jaws to simultaneously advance or retract simultaneously, automatic centering andclamping can be completed, the handle is shifted to rotate the angle of the two ratchet teeth and limits, at the moment, the position of each clamping jaw can be adjusted by using a four-angle wrench, clamping of a cylindrical material such as an ellipse, a rectangle and the like can be completed, the disc-type part clamping assembly can clamp the disc-shaped part conveniently and is convenient to disassemble and install, the clamping part can be quickly installed during application, and the clamping part can be quickly disassembled when not in use.
