Inner ring fine grinding device for bearing machining and grinding method of inner ring fine grinding device

Abstract

The invention discloses an inner ring fine grinding device for bearing machining and a grinding method of the inner ring fine grinding device. The invention relates to the technical field of bearing grinding. The device is composed of a clamping mechanism and a grinding mechanism. The problems that an existing part of bearing inner ring grinding device cannot efficiently grind a bearing inner ring, part of devices cannot effectively carry out accurate positioning and clamping on the axis of a bearing and the axis of a grinding motor, and part of the devices cannot effectively remove dust in the grinding process are solved; a T-shaped block slides in the interior of a movable groove by rotating a screw rod, an arc-shaped magnet fixedly connected to the T-shaped block is adjusted to be attracted to the side end of the bearing inner ring, limiting is carried out on the bearing inner ring, and therefore the effect that fine grinding is rapidly and efficiently carried out on the bearing inner ring is realized; and two nut blocks with surfaces in threaded connection are driven to synchronously and relatively move by rotating a rotating rod to clamp and fix a bearing outer ring, and therefore it is ensured that the clamped bearing and the rotating end of the motor can be always kept on the same axis, and the precision in the bearing grinding process is improved.

Description

technical field [0001] The invention relates to the technical field of bearing grinding, in particular to an inner ring fine grinding device for bearing processing and a grinding method thereof. Background technique [0002] Bearing is an important part of contemporary mechanical equipment. Its main function is to support the mechanical rotating body, reduce the friction coefficient during its movement, and ensure its rotation accuracy. It is used to support the shaft, but this is only part of its function. The essence of support is to be able to bear radial loads. Accuracy of bearing dimensions; [0003] The existing patent (notification number: CN110253353A) discloses an inner ring grinding device for bearing manufacturing, which relates to the field of bearing manufacturing. When processing the existing bearing inner ring, the bearing inner ring is usually not fixed firmly, which affects the grinding of the bearing inner ring processing. In the process of realizing the...
