Abstract

An annular part grinding fixture comprises a taper handle shaft of hollow structure, an outer taper shaft, an inner taper shaft and a pushing disc. An outer taper face is arranged at one end of the outer taper sleeve, and an inner taper face is arranged at one end of the inner taper sleeve; the outer surface of the outer taper sleeve is sleeved with the inner taper sleeve, and the outer taper face of the outer taper sleeve is matched with the inner taper face of the inner taper sleeve; the outer taper sleeve is fixedly connected with the taper handle shaft, and the inner taper sleeve is fixedly connected with the pushing disc; and the pushing disc is arranged in the outer taper sleeve, and a plurality of axial opening gaps are formed in the outer taper sleeve in the circumferential direction. The annular part grinding fixture is simple in structure, convenient to use, capable of achieving automatic centering, and high in centering precision; and clamping force is controlled, so that clamping deformation can be reduced, and the machining precision is ensured.

Description

technical field [0001] The invention relates to a grinding fixture, in particular to an auxiliary clamping grinding fixture for annular thin-walled parts. Background technique [0002] Due to the poor rigidity of thin-walled ring parts, it is easy to deform if clamped by a three-jaw chuck during processing, and the processing accuracy is difficult to guarantee. Contents of the invention [0003] The present invention solves the above technical problems and provides a ring part grinding fixture with simple structure, high positioning accuracy and effective reduction of clamping deformation. [0004] In order to solve the above-mentioned technical problems, the present invention adopts a ring-shaped part grinding fixture, which includes a hollow taper shank, an outer taper sleeve, an inner taper sleeve and a push plate. One end of the outer taper sleeve is provided with an outer taper surface, so that One end of the inner cone sleeve is provided with an inner cone surface, ...
