Description

Technical Field

[0001] The utility model relates to the technical field of rough grinding of end faces of bearing rings, in particular to a rough grinding tool for end faces of bearing rings. Background Art

[0002] During the processing of the bearing ring, both ends of the bearing ring need to be polished to ensure its flatness, so a bearing ring end face rough grinding device is required.

[0003] Some bearing ring end face rough grinding devices currently on the market: for example, the utility model patent with authorization announcement number CN216228417U discloses a bearing ring double end face grinding device. When the device is used, the bearing ring is placed in the installation groove, and the feeding rotating component drives the upper end of the feeding plate to rotate toward the grinding component. The installation groove drives the bearing ring to move, so that the bearing ring is ground between the two grinding components. During the processing, there is no need to manually place the bearing ring between the grinding components, which improves work efficiency and ensures processing quality. However, since the device lacks an adjustment mechanism, it cannot be adjusted according to the actual length size of the bearing ring to be processed, and can only be used for bearing rings of a single size, and cannot cope with the processing of bearing rings of various lengths and sizes, which needs to be improved.

[0004] Therefore, we propose a bearing ring end face rough grinding tool to solve the above-mentioned problems. Utility Model Content
