Problems solved by technology

Grinding the inner spherical surface can be done directly with a shaped grinding wheel, but this method produces a large grinding force, is very sensitive to the existence of the bearing insertion groove, and is prone to deviation, and the shaped grinding wheel needs to be reground frequently, resulting in high tool costs and low processing efficiency
Grinding the inner spherical surface can also be done with a sheet-shaped grinding wheel with R for CNC grinding. This method has a small cutting force and is not sensitive to the existence of the bearing insertion groove. The change will affect the compensation amount of the tool in CNC machining, thus affecting the shape and size of the inner spherical surface

Abstract

The invention discloses a method for processing the inner spherical surface of a bearing seat through motion forming. The inner spherical surface of the bearing seat is ground with a diamond grinding wheel, which can be used for a long time without shaping and grinding, because the processing method of the present invention is formed by a motion The method of grinding the inner spherical surface adopts three numerical control feeding steps of diamond grinding wheel spherical center feeding, bearing seat spherical center feeding and diamond grinding wheel spherical diameter feeding, and uses the compound rotation circle of the bearing seat and the rotation circle of the diamond grinding wheel to form The ball is used to complete the grinding of the inner spherical surface of the bearing seat. The invention discloses a method for processing the inner spherical surface of the bearing seat through motion forming, without the need of correcting the grinding wheel, the grinding wheel has a long service life, and the processing accuracy and efficiency are high.

Description

technical field [0001] The invention relates to the technical field of bearing seat processing, in particular to a method for processing the inner spherical surface of the bearing seat through motion forming. Background technique [0002] Because there are two cast bearing insertion grooves on the inner spherical surface of the outer spherical ball bearing seat, the two cast bearing insertion grooves make the casting stress distribution of the inner ball hole of the bearing seat asymmetrical. After the inner spherical surface is turned by CNC, the casting stress is released It will cause a large shape error on the inner spherical surface, and the shape error can reach 0.10mm, which is much higher than the dimensional tolerance of the inner spherical surface. Only by removing this shape error, the limit speed of the bearing seat can be increased and the noise can be reduced. [0003] Adding a process of grinding the inner spherical surface after the CNC finish turning inner s...
