[0002] Rollers are components that bear loads when bearings are running. Existing rollers are divided into spherical rollers and tapered rollers. During the soft grinding process of the rolling surface of the tapered roller, the end face of the tapered roller needs to be clamped;

[0003] In the prior art, a patent with authorization publication number CN 218397600 U discloses a clamping device for soft grinding of rolling surfaces of tapered rollers, which rotates the bending part of the L-shaped adjustment plate, lifts the tapered rollers between the L-shaped adjustment plates, and moves the tapered rollers along the sides of the L-shaped adjustment plates. After continuous operation, each group of three L-shaped adjustment plates can limit the end faces of the tapered rollers, thereby locating the center of the end faces of the tapered rollers. During the limiting process, part of the L-shaped adjustment plate is located on the side faces of the end portions of the tapered rollers. Since the L-shaped adjustment plate rotates synchronously with the tapered rollers, a shielding effect is generated, and this part is located on the rolling surface of the tapered rollers, making it impossible to grind them, thereby reducing the processing quality of the tapered rollers.
