Problems solved by technology

[0002] Dynamic and static pressure bearings require processing several evenly distributed deep cavities and shallow cavities on the inner circle. The grinding machine cannot be indexed to ensure the uniform distribution of several cavities. At present, manual cavity opening is mostly used, and the cavity opening position needs to be drawn, but there is artificial Inaccurate and difficult to control opening strength

Abstract

The invention provides a fixture for machining a depth cavity for dynamic and static pressure bearings by using an inner-aperture grinder. The fixture comprises a sleeve provided with an annular boss, angle control screw holes are radially and evenly distributed on the annular boss, angle control screws are arranged on the angle control screw holes, stop rods are fixed onto the inner-aperture grinder, each stop rod is positioned between the two corresponding angle control screws, and fixing screw holes and fixing screws for fixing the bearings are arranged on two end faces of the sleeve. The fixture has the advantages that the structure is simple, the machining angle travel of the depth cavity is determined by using the fixture for indexing, the cavity is conveniently machined, working efficiency is improved, cavity machining evenness is ensured, and qualification rate is increased.

Description

technical field [0001] The invention relates to a tooling for processing bearings, in particular to a tooling for deep and shallow cavities of dynamic and static pressure bearings processed by an inner hole grinder. Background technique [0002] Dynamic and static pressure bearings require processing several evenly distributed deep cavities and shallow cavities on the inner circle. The grinding machine cannot be indexed to ensure the uniform distribution of several cavities. At present, manual cavity opening is mostly used, and the cavity opening position needs to be drawn, but there is artificial There are errors and the opening strength is not easy to control. Contents of the invention [0003] The object of the present invention is to provide a tooling for deep and shallow cavities of dynamic and static pressure bearings processed by an inner hole grinder which has a simple structure and ensures uniform distribution of deep and shallow cavities. [0004] The present in...
