Description

Technical Field

[0001] The utility model relates to the technical field of super-fine oilstone preparation, in particular to a super-fine oilstone dressing device for a bearing ring. Background Art

[0002] Super-fine oilstones are mainly used for grinding precision workpieces, such as optical components, precision instrument parts, molds, etc. These workpieces have extremely high requirements for surface finish and precision. Therefore, the processing and production of super-fine oilstones also require fine grinding and correction. At present, when grinding and correcting super-fine oilstones, they are either polished by hand-held oilstones or polished by prefabricated tools that are compatible with polishing oilstones.

[0003] However, the manual hand-held oilstone grinding method completely relies on the work experience of the staff, which not only cannot guarantee the accuracy of the oilstone curvature, but is also prone to safety accidents. Although the prefabricated tool method can ensure the accuracy of oilstone grinding and avoid the occurrence of safety accidents, the prefabricated tool can only be adapted to the corresponding oilstone size. When it is necessary to grind and correct oilstones of other sizes, new tools need to be prefabricated again, resulting in a greatly increased cost of oilstone grinding and correction, and an additional workload for the staff. Therefore, there is an urgent need for a bearing ring ultra-fine oilstone dressing device that can effectively clamp and grind oilstones of different sizes. Utility Model Content
