Expanding sleeve centering clamp

Abstract

The invention relates to an expanding sleeve centering clamp which comprises a clamp body, an expanding sleeve round petal body and a guide sliding pillar. The guide sliding pillar is arranged in the clamp body in a sleeved mode, a cavity is formed in the position where the guide sliding pillar and the clamp body are connected, and a spring which is connected with the guide sliding pillar and the clamp body is arranged in the cavity. A groove is formed in the surface of the outside of the position where the guide sliding pillar and the clamp body are connected, the expanding sleeve round petal body is arranged in the groove in a sleeved mode, and the two sides of the groove are arranged to be inclined planes. A center hole is formed in the end face of the tail portion of the guide sliding pillar. The clamp body is further provided with a ball nut, and a ball gasket is further arranged between the ball nut and the expanding sleeve round petal body. The expanding sleeve centering clamp has the advantages that automatic correction can be achieved, centering is achieved, dismounting and mounting are convenient, precision is high, and parts of different inner diameters can be machined.

Description

technical field [0001] The invention relates to the technical field of machining fixtures, in particular to an expansion sleeve centering fixture. Background technique [0002] In mechanical processing, some workpieces are positioned and clamped through their inner holes, but the existing fixtures are either complex in structure, or cumbersome to unload, and most of them cannot achieve self-centering, and often cannot meet the requirements of the conditions , resulting in poor machining accuracy, different fixtures are required for parts of different sizes, the auxiliary time is long, and the efficiency is low. Contents of the invention [0003] In view of the above problems, the object of the present invention is to provide an expansion sleeve centering fixture capable of automatic correction, centering, convenient disassembly and assembly, high precision, and capable of processing parts with different inner diameters. [0004] Realize the technical scheme of the present...
