Problems solved by technology

[0003] The existing processing technology has extremely high requirements on the front process, and the quality of the front process directly affects the processing quality of this process. At the same time, in order to eliminate the roller indentation in this process, an outer cylindrical grinding process is required, which causes a long processing time for the entire bearing process. Long, low efficiency, resulting in high cost of finished bearings, has been difficult to drop

Embodiment approach 1

[0015] Embodiment 1: The bearing outer ring groove grinding process of the present invention, wherein,

[0016] Electromagnetic centerless fixture: fix the end face of the outer ring of the bearing to be processed, and the electromagnetic centerless fixture can rotate with the outer ring of the bearing; pressure rotor: position the outer ring of the bearing to ensure that the outer ring of the bearing is rotated in a positive manner The track of the circle rotates; the roller: drives the outer ring of the processed bearing to rotate. In this embodiment, the rotating surface of the roller is attached to the surface of the outer ring of the bearing, and no trace will be left on the surface of the outer ring of the bearing, which means This means that the subsequent step of correcting the outer ring of the bearing is canceled; finally, the groove of the outer ring of the bearing that has been positioned and clamped is ground.

[0017] In this embodiment, the roundness of the chan...

Abstract

The invention relates to a bearing outer ring processing method, in particular to a bearing outer ring groove grinding process. The invention discloses the bearing outer ring groove grinding process, wherein an electromagnetic centerless fixture is used for fixing the end surface of a processed bearing outer ring; a pressure rotor is used for positioning the processed bearing outer ring; a roller is used for driving the processed bearing outer ring to rotate; and the positioned and clamped bearing outer ring groove is grinded. The bearing outer ring groove grinding process improves the processing efficiency of the bearing outer ring groove, shortens existing process steps, and reduces the production cost.

Description

technical field [0001] The invention relates to a processing method for an outer ring of a bearing, in particular to a groove grinding process for an outer ring of a bearing. Background technique [0002] At present, the groove grinding of the outer ring adopts the outer diameter as the reference, the double roller positioning, and then the grinding process. This process has high requirements on the roundness of the outer circle of the bearing, and the error of the outer circle will be directly reflected in the groove. At the same time, due to the positioning of the double rollers, there are roller indentations on the outer circular surface. Before entering the assembly, a grinding process is required to remove the outer roller marks. [0003] The existing processing technology has extremely high requirements on the front process, and the quality of the front process directly affects the processing quality of this process. At the same time, in order to eliminate the roller i...
