The invention discloses a flexible superfinishing device and method for tapered roller convexity. The processing device includes a loading device, a workpiece positioning device and a workpiece driving device. The loading device includes, from top to bottom, a support, two loading rods, a base plate, an elastic steel sheet, and an elastic grinding tool. The workpiece positioning device is composed of two positioning rods arranged symmetrically. The workpiece driving device is composed of two tapered guide rollers arranged in the same direction. The processing method includes: (1) first place the workpiece between two tapered guide rollers, and then use two positioning rods to position the two ends of the workpiece; (2) adjust the shape of the grinding tool through the loading device, and then adjust the shape of the workpiece Apply load; (3) Drive the workpiece to roll through the rotation of the tapered guide roller, and the elastic abrasive tool starts to process the surface of the workpiece. The invention can realize the high shape precision, high surface quality and high flexibility superfinishing of different shape convexities of the tapered rollers.
Description
Technical field [0001] The invention relates to the technical field of equipment manufacturing, in particular to a flexible superfinishing device and a method for the convexity of a tapered 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. As a rolling element, tapered rollers play a vital role in the performance and life of tapered roller bearings. In order to enable tapered 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 bus bar of the tapered rollers needs to be designed with a convex shape and is required for different working conditions. The convex shape is also different. The study of the convexity of tapered rollers is of great significance for improving the ser...
