Problems solved by technology
[0003] At present, the main processing method for superfinishing the outer circular surface of convex cylindrical rollers in actual production is still centerless through-type superfinishing, which mainly relies on the geometry of the threaded guide roller to ensure the roller crown profile The shape accuracy is especially suitable for mass production of fixed-type cylindrical rollers. However, once the product demand is updated and the design requirements for the convex shape of cylindrical rollers change, the manufacturer will have to replace new guide rollers or rework the guide rollers. Shape modification, at this time, the production cost increases sharply, hindering the product update of the production enterprise, reducing production flexibility and overall efficiency

The invention discloses a flexible ultra-fine grinding and polishing processing device and method for the outer circle of a convex cylindrical roller. The tool assembly includes a grinding tool base and a grinding tool fixedly arranged at the bottom of the grinding tool base. The lower profile of the tool forms a concave curved surface to fully contact the outer surface of the convex cylindrical roller; the workpiece driving device includes a driving mechanism and two guide rollers that are driven by the driving mechanism and rotate in the same direction and at the same speed. In addition, the present invention also discloses a method for grinding and polishing the outer circular surface of a convex cylindrical roller through the processing device to obtain a high-quality cylindrical roller with a convex outer surface, which has the ability to realize and improve the cylindrical roller with various specifications. Shape accuracy, surface quality and production flexibility of outer circles.
Description
technical field [0001] The invention relates to the technical field of equipment manufacturing, in particular to a flexible ultra-finishing grinding and polishing processing device and method for the outer circle of a convex cylindrical roller. Background technique [0002] Bearings are key precision basic components in the equipment manufacturing industry. The performance of bearings directly determines the performance, life and reliability of major equipment and host products. Cylindrical rollers, as the rolling elements of bearings, play a vital role in the performance and life of cylindrical roller bearings. In order for cylindrical rollers to withstand high-strength loads, it is necessary to avoid or slow down the "edge effect" of stress concentration at both ends of the rollers. Therefore, the generatrix of cylindrical rollers must be designed in a convex shape to form convex cylindrical rollers, and different The convexity shapes required by different working conditi...
