Abstract

The invention relates to a self-centering power chuck of a circular arc-shaped groove; a faceplate is closely arranged below a chuck body; a trapezoidal slider is arranged in a trapezoidal groove which is arranged on the chuck body; a pin shaft is fixed below the trapezoidal slider and is inserted in a linear long groove hole of the chuck body and in the circular arc-shaped groove of the faceplate; jaws can be fixed at different positions on the trapezoidal slider; the cylinder body of an oil cylinder is arranged on the chuck body through an oil cylinder shaft, and the cylinder rods of the oil cylinder are arranged on the faceplate through a connector and a connector shaft; a connecting flange is fixedly arranged on the chuck body and is pressed on the faceplate; and the connecting flange can be fixed on a machine tool. Compared with the prior art, the self-centering power chuck of the circular arc-shaped groove has the advantages of simple structure, convenience in processing, low processing cost and large stroke of the jaws.

Description

technical field [0001] The invention relates to a chuck used on a machine tool, in particular to an arc groove self-centering power chuck. Background technique [0002] At present, most of the self-centering chucks used on various machine tools are coil wire-bevel gear pair or screw pair-bevel gear pair structure. The processing costs of the coil wire, screw pair, and bevel gear pair are high, and the coil wire -The bevel gear pair structure has a small claw stroke; most of the self-centering power chucks are wedge-shaped, and its structure is complex, and the claw stroke is also small. Contents of the invention [0003] The object of the present invention is to provide a circular arc groove self-centering power chuck for the above-mentioned deficiencies in the prior art. The stroke of the claw is large, and the clamping range is large. [0004] The present invention can be implemented through the following technical solutions: a self-centering power chuck with arc groov...
