Abstract

The invention discloses a shaft processing fixture, which comprises a fixture body, a pressing piece and holddown bolts. A holding groove is arranged in the center of the top of the fixture body, the section of the holding groove is arc-shaped, a left side surface and a right side surface, which contact with the holding groove, of the pressing piece are arc-shaped surfaces, and the pressing piece is positioned on the upper side of the holding groove and fixedly presses a workpiece into the holding groove by the aid of the holddown bolts at the front end and the rear end of the pressing piece. By the aid of the shaft processing fixture, the pressing area of the workpiece is increased, clamping stability of the workpiece is improved, and processing precision of the workpiece is guaranteed.

Description

technical field [0001] The invention relates to a jig for machining, which belongs to the technical field of auxiliary fixing jigs for machining because it is a jig for machining shaft parts. Background technique [0002] In order to assist the normal processing of mechanical parts, ensure the stability of the workpiece to be processed, and improve the processing accuracy of the workpiece, it is generally equipped with various fixed chucks and fixed fixtures. For example, when milling on a milling machine, the workpiece is generally fixed on the workbench by a vise for milling. But for some shaft workpieces, such as attached figure 1 The workpiece 1 shown in , since the shape of the workpiece is an arch formed by a circular arc surface and a plane, in the last process of processing, the top surface 2 of the workpiece must be milled or ground for finishing, and Drilling operations are carried out on this plane. The curved surface of the workpiece makes it difficult to fix ...
