Description

Technical Field

[0001] The utility model relates to the technical field of bearing processing, in particular to a supporting structure for grinding the outer diameter of a thin-walled bearing. Background Art

[0002] It is well known that the contact surface and angle between the support and the outer ring of the workpiece need to be adjusted during the processing of the outer diameter of the thin-walled bearing, resulting in that only the accuracy of the thick-walled bearing workpiece can be guaranteed to meet the process requirements during the processing. In the processing of thin-walled bearing workpieces, not only is it necessary to repeatedly adjust the angles and contact surfaces of multiple support structures, which affects the work efficiency; since the existing support structure and the thin-walled bearing workpiece are in surface contact, the rigidity is relatively high and is not conducive to grinding. There is a problem of large deformation in the processing of thin-walled bearing workpieces, resulting in large production waste and rework; therefore, it has become a basic demand of technical personnel in this field to propose a support structure that does not require repeated adjustment of the angle and contact point during use and is suitable for the grinding of the outer diameter of thin-walled bearings.

[0007] In the support structure for grinding the outer diameter of the thin-walled bearing, both the fillet A and the fillet B are chamfered.

[0008] In the support structure for grinding the outer diameter of the thin-walled bearing, the bottom support at the bottom of the transition plate is tightened against the bottom of the T-slot through bolts in the vertical long holes, and the upper part of the bottom support is arranged in an arc shape.

[0009] In the support structure for grinding the outer diameter of the thin-walled bearing, the midpoint of the inner annular surface of the support block and the axis of the bearing ring are on the same horizontal plane.

[0010] In the support structure for grinding the outer diameter of the thin-walled bearing, the inner surface of the transition plate does not contact the outer diameter of the bearing ring.

[0011] Due to the adoption of the above technical solution, the utility model has the following beneficial effects:

[0012] The support structure for grinding the outer diameter of a thin-walled bearing described in the utility model has three support points on the inner surface of a support block that are in contact with the bearing ring. When in use, only the bolts in the oblong holes on the support block need to be adjusted. One adjustment can achieve that the three support points are in contact with the outer diameter surface of the bearing ring, thereby providing a stable support force for the grinding force from the opposite direction. The utility model has a simple structure and is easy to use. It is suitable for the processing of thin-walled bearings. Compared with existing support structures, it has better stability, strong deformation resistance, and shock absorption capability. BRIEF DESCRIPTION OF THE DRAWINGS
