Abstract

The invention discloses an inner hole processing fixed fixture of ring-like parts. The fixture comprises a taper handle shaft, an outer taper sleeve and an inner taper sleeve, wherein an outer conical surface is arranged at one end of the outer taper sleeve; an inner conical surface is arranged at one end of the inner taper sleeve; the inner taper sleeve coats the outer surface of the outer taper sleeve; the outer conical surface of the outer taper sleeve fits the inner conical surface of the inner taper sleeve; fit threads are arranged on left end planes of the outer taper sleeve and the inner taper sleeve; the outer taper sleeve and the inner taper sleeve are connected through the threads; the outer taper sleeve and the taper handle shaft are fixedly connected; and multiple axial opening gaps are formed in the outer taper sleeve in a peripheral direction. The fixture is simple in structure and convenient to use, can realize automatic centering to achieve high centering precision, and can reduce the clamping deformation to guarantee the processing precision through controlling the clamping force.

Description

Technical field [0001] The invention relates to the technical field of mechanical processing auxiliary clamping, in particular to a fixing clamp used for processing inner holes of ring parts. Background technique [0002] Because of the poor rigidity of thin-walled ring parts, it is very easy to deform if a three-jaw chuck is used to clamp during processing, and the processing accuracy is difficult to guarantee. Summary of the invention [0003] The present invention solves the above technical problems and provides a ring-shaped part grinding fixture with simple structure, high positioning accuracy, and effectively reducing clamping deformation. [0004] In order to solve the above technical problems, the present invention adopts a fixing fixture for inner hole machining of ring parts, which includes a taper shank, an outer taper sleeve and an inner taper sleeve. One end of the outer taper sleeve is provided with an outer cone surface, and the inner cone One end of the sleeve is pr...
