Embodiment Construction

[0022] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations.

[0023] Such as figure 1 As shown, a fixture for a circular thin-walled workpiece 5 includes a disc-shaped disc body 1, a fixed seat 2 in an annular array and clamping jaws 3 arranged on the fixed seat 2 are integrally formed on the surface of the disc body 1 ; The front part of the jaw 3 is folded down to form a hook 31 for clamping; the end of the hook 31 has an inclined surface 32 . The inclined surface 32 is provided on the inner side of the hook 31 and is inclined from top to bottom and from inside to outside. A spacer 4 against the end face of the workpiece 5 is installed on the fixed seat 2 inside the hook 31; an annular groove 51 is provided on the side wall of the workpiece 5; the end of the hook 31 extends into the groove 51, the incl...

Abstract

The invention relates to a clamp for machining a round thin-walled workpiece. The clamp comprises a chuck body, fixing bases annularly arrayed on the chuck body and clamping jaws arranged on the fixing bases, wherein the front portion of each clamping jaw is folded to form a hooking jaw used for clamping, the end of each hooking jaw is provided with an inclination face, a cushion block for abutting against the end face of the workpiece is installed on each fixing base at the inner side of the corresponding hooking jaw, annular grooves are formed in the side walls of the workpiece, the ends ofthe hooking jaws stretch into the grooves, the inclination faces of the hooking jaws abut against notches of the grooves, and then the workpiece is driven to abut against the cushion blocks. Accordingto the technical scheme, the inclination faces are utilized for abutting against the ports of the grooves in the side walls of the workpiece, and then radial clamping force and axial thrust force towards the cushion blocks can be provided for the workpiece. In this way, it is guaranteed that the clamping jaws can firmly clamp the workpiece, the clamp applies acting force to the workpiece throughthe inclination faces, the acting force can be broken down into small component force in the axial direction and radial direction of the workpiece, the risk of radial deformation of the workpiece canbe effectively lowered, the circularity of the workpiece is guaranteed, and the yield is increased.

Description

technical field [0001] The invention relates to the technical field of fixtures, in particular to a fixture for processing circular thin-walled parts. Background technique [0002] The chuck is a mechanical device used to clamp a circular workpiece on a machine tool. It uses the radial movement of the movable jaws evenly distributed on the chuck body to position the workpiece from the side wall of the circular workpiece. [0003] When processing circular thin-walled workpieces, since the existing chuck can only clamp the side wall of the circular thin-walled workpiece, the workpiece fixed on the chuck is subject to a single force, which requires a large radial clamping force to ensure The workpiece is firmly fixed. However, the large radial clamping force easily deforms the workpiece, resulting in the roundness of the workpiece not meeting the performance requirements. Contents of the invention [0004] In order to solve the problem that the roundness of the thin-walled ...
