Abstract

The invention discloses an open type three-jaw self-centering chuck. A chuck lower base and a chuck upper base are assembled together, a through hole is formed in the middle of the chuck lower base and the middle of the chuck upper base, annular grooves are formed on the chuck faces of the chuck lower base and the chuck upper base, and the annular grooves are concentric with the circle of the through hole; a clamping jaw driving screw assembly and a clamping jaw assembly are arranged at the 120-degree interval of the circumferences of the annular grooves in the circle center direction; a driving gear and a plurality of driven gear assemblies are further arranged in the annular grooves; the driving gear, the driven gear assemblies and a gear at the tail end of the driving screw assembly aremeshed with one another to form a motion relation; and a driving device is arranged outside the driving gear and on the side surface of the chuck lower base. The three-jaw chuck is self-centering, light in weight, large in clamping force and not prone to falling off, meanwhile, large stroke is achieved, clamping of long-shaft parts is convenient, the stroke of the long-shaft parts can exceed 60mmthrough clamping and loosening of the clamping jaw assembly, and the three-jaw chuck is suitable for shaft parts with various shaft diameters.

Description

Technical field [0001] The present invention relates to a tool for machine tool, and is specifically an open tripopathy self-central chuck. Background technique [0002] Application No. 201920498392.7 relates to a three-jaw self-central chuck, and the pulling of the chuck is rotated by the umbrella gear, and the sliding seat is slid in the radial slot on the outer casing to achieve a self-destructive movement of the jaw. [0003] This technology is consistent with the traditional end-faced thread clamping. [0004] The three-claw structure of a trip chuck disclosed in the disclosure, is intended to provide a three-claw structure of a clamping square workpiece that is convenient to provide a fitting. [0005] The agency implements the clamping square workpiece, but the product has a thickness, and the clamping force is not large. Inventive content [0006] In order to achieve a self-care, light quantification, clamping force of the trip chuck, it is not easy to fall off, and the ...
