Abstract

The invention discloses a workpiece clamping device with an elastic sheet positioning reference, and belongs to the technical field of tooling fixtures. The workpiece clamping device comprises a disc body and clamping jaws, wherein the clamping claws comprise a first clamping jaw and a second clamping jaw; a first positioning member is arranged on the first clamping jaw; the second clamping jaw is provided with a second positioning member; the first positioning member and the second positioning member perform are positioned in a cooperative manner; the first positioning member consists of a first positioning member body and an elastic sheet; an elastic sheet positioning opening is formed in the upper end part of the elastic sheet; a second positioning member positioning opening is formed in the upper end part of the second positioning member. The workpiece clamping device disclosed by the invention is simple in structure, convenient to use, and safe and reliable, and can meet drawing requirements. Through the adoption of the workpiece clamping device, a processing surface and the axis of a workpiece can be effectively guaranteed to be parallel to each other, so that the positioning circle of the workpiece does not deviate when the workpiece is fastened.

Description

technical field [0001] The invention relates to a three-jaw chuck, in particular to a workpiece clamping device with a shrapnel positioning reference, and belongs to the technical field of fixtures. Background technique [0002] The chuck is a mechanical device used to clamp the workpiece on the machine tool. It uses the radial movement of the movable jaws evenly distributed on the chuck body to clamp and position the workpiece. The chuck is generally composed of the chuck body, the movable The jaws and jaw driving mechanism are composed of 3 parts. The diameter of the chuck body is at least 65mm and the maximum can reach 1500mm. There is a through hole in the center for passing workpieces or bars; the back has a cylindrical or short tapered structure, which can be directly or through the method The blue disc is connected with the end of the main shaft of the machine tool, and the chuck is usually installed on lathes, cylindrical grinders and internal grinders, and can also ...
