Description

Technical Field

[0001] The utility model relates to the technical field of bearing ring production equipment, and more specifically to a bearing ring processing device for bearing production and processing. Background Art

[0002] A bearing is an axially rotating part. The bearing includes a bearing ring and a roller. The bearing ring is an annular part of a radial rolling bearing with one or more raceways. When processing the bearing ring, it needs to be ground on the outer circle after end face grinding. The hard friction in rolling grinding will generate a lot of heat. Choose a fully synthetic cutting fluid for rough grinding.

[0003] The existing announcement number is CN217371867U, and the name is a bearing ring processing device for bearing production and processing. The synchronous drive mechanism is started to drive the two clamping plates to move in opposite directions. The two clamping plates are always symmetrical about the center of the top of the base, and can quickly clamp bearing rings with different inner diameters, and can center the bearing rings in the top center position of the base, saving time and effort, reducing the labor intensity of the staff, and improving the grinding efficiency. By starting the hydraulic cylinder to drive the extrusion plate to clamp the outer circumferential side wall of the bearing ring, the stability of the bearing ring is further improved, and the bearing ring is prevented from rotating during the grinding of the end face of the bearing ring.

[0004] However, when grinding the bearing ring, two clamping plates are used to squeeze the inner ring of the bearing ring, and the outer circumference of the bearing ring is clamped by the extrusion plate, and then the bearing ring is ground using a grinding device. During grinding, the grinding position needs to be constantly switched to complete the grinding of the outer circumference of the bearing ring. In this grinding method, the grinding position is switched manually, and part of the outer circumference of the bearing ring is blocked by the extrusion plate. The bearing ring needs to be disassembled manually to rotate the grinding position. The switching and splitting processes are time-consuming, resulting in reduced grinding efficiency.
