Abstract

The invention discloses a workpiece chuck. Clamping claws on the chunk move synchronously through an umbrella structure composed of connecting rods and a telescopic device. Compared with a traditional chunk with a spiral clamping mode, the workpiece chuck has fewer errors and better synchronization, and clamping force can be adjusted very conveniently through adjustment on the telescopic device. Compared with a traditional rotating type clamping mode, the workpiece chuck is more rapid and accurate in opening and clamping.

Description

technical field [0001] The invention relates to a workpiece chuck, which belongs to the field of mechanical processing. Background technique [0002] Traditional drilling machines and horizontal milling machines use bench vises to fasten workpieces, but this clamping method has poor positional accuracy and poor clamping stability, while traditional three-jaw chucks After a long time of use, the position of the workpiece after clamping cannot be guaranteed. Contents of the invention [0003] The purpose of the present invention is to provide a technical solution that can solve the above problems. [0004] The present invention is realized by following method: [0005] A workpiece chuck, comprising several clamping claws, guide rails with the same number as the clamping claws, and a chuck body, the guide rails are arranged in an array pointing to the center of the chuck body, and the clamping claws are installed into the chuck body through the guide rails , the chuck also...
