Generating inner spherical bearing grinder

Abstract

The invention provides a generating inner spherical bearing grinder, which is used for improving the precision of a self-aligning bearing and is capable of replacing a self-aligning bearing superfinishing machine to finish superfinishing, so that the superfinishing of an inner spherical bearing can be finished only through one-time grinding, and the grinding efficiency is high. The generating inner spherical bearing grinder comprises a lathe bed, a feeding sliding plate, a headstock, an electric main shaft, an electromagnetic fixture, a sand wheel, a finisher, a grinding head seat and a grinding head sliding plate, wherein the feeding sliding plate and the grinding head sliding plate are supported on the lathe bed through an X-axis guide rail and a Y-axis guide rail respectively, the X-axis guide rail and the Y-axis guide rail are vertical to each other, the finisher and the headstock are supported on the upper end face of the feeding sliding plate respectively, the grinding head seat is supported on the upper end face of the grinding head sliding plate, the electromagnetic fixture is arranged at the outer part of the headstock in a protruding manner and is clamped with a workpiece, the electric main shaft protrudes from the grinding head seat, and the sand wheel is sleeved on the protruding end of the electric main shaft. The generating inner spherical bearing grinder is characterized in that the part, positioned below the workpiece, of the headstock is provided with an adjustable rotating shaft structure.

Description

technical field [0001] The invention relates to the structural technical field of grinding machines, in particular to a Fan Cheng method internal spherical bearing grinding machine. Background technique [0002] The grinding wheel of the existing Fancheng grinding machine does not need to be trimmed. The grinding wheel wears out during the continuous working process, and the machine tool cannot perform grinding wheel compensation, which results in a large dimensional difference of the workpiece, and because the grinding wheel shaft is small, the inner bearing is easy to wear. [0003] And the grinding wheel of existing forming method grinding machine is directly trimmed into the outer spherical surface with a dresser, and then the outer spherical surface of the grinding wheel is copied to the inner spherical surface of the bearing ring. The smoothness of grinding by this method is about 0.8. For P5 grade bearings, the above two machine tools are often used in the pre-fin...

Problems solved by technology

[0002] The grinding wheel of the existing Fancheng grinding machine does not need to be trimmed, the grinding wheel wears out during the continuous working process, and the machine tool cannot perform grinding wheel compensation, which results in a large dimensional difference of the workpiece, and because the grinding wheel shaft is small, the inner bearing is easy to wear

[0003] However, the grinding wheel of the existing forming grinding machine is directly trimmed into an outer spherical surface with a dresser, and then the outer spherical surface of the grinding wheel is copied to the inner spherical surface of the bearing ring. The grinding smoothness of this method is about 0.8

For P5 bearings, the above two machine tools are often used in the pre-finishing process, but not for final processing, which makes the super-finishing of inner spherical bearings need to be ground twice, and the grinding efficiency is low
