A special superfinishing machine for bearings and a grinding device for positioning rings of grinding machines

Abstract

The invention discloses a super-fine machine locating ring and grinding machine locating ring grinding device specifically used for a bearing. The super-fine machine locating ring and grinding machine locating ring grinding device specifically used for the bearing comprises a main supporting frame, a reinforced supporting frame, a supporting plate, a grinding wheel spindle shell, a grinding wheel spindle and a grinding wheel; the lower end of the main supporting frame is connected with a supporting seat; one end of the reinforced supporting frame is connected with a workpiece shaft box body and the other end of the reinforced supporting frame is connected with the main supporting frame; the supporting plate is connected with the upper end of the main supporting frame; the grinding wheel spindle shell is mounted above the supporting plate; the grinding wheel spindle is rotationally connected on the grinding wheel spindle shell and the grinding wheel is connected with one end of the grinding wheel spindle; the other end of the grinding wheel is connected with an inner hexagon screw; the screw head of the inner hexagon screw is connected with a straight allen wrench in an inserting manner and the allen wrench is connected with a hand-held electric drill. The device is installed directly on a super-fine machine for grinding a locating ring, so that the locating ring does not need to be removed; moreover, the locating ring is ground directly on the super-fine machine, so that the cumulative error of axial jumpiness of the front end surface of the locating ring caused by a combination of the axial jumpiness of the front end surface of a workpiece shaft and the parallel error between the front end surface and the rear end surface of the locating ring can be avoided.

Description

technical field [0001] The invention belongs to the field of bearing processing equipment, and in particular relates to a special superfinishing machine for bearings and a grinding device for positioning rings of grinding machines. Background technique [0002] In the bearing industry, the front end face of the superfinishing machine and grinding machine locating ring is directly in contact with the rear reference end face of the processed bearing ring, which plays a role in supporting, positioning and guiding the rotation of the ring. The rotation accuracy of the positioning ring, especially the axial runout of the front end face, directly affects the rotation accuracy of the ferrule, and then affects the grinding and superfinishing accuracy of the ferrule. Since the superfinishing machine does not have a grinding wheel, it cannot use its own grinding wheel to repair the worn front end of the positioning ring like a grinding machine, so the repair of the worn end of the pos...

Problems solved by technology

Re-installing it on the front end of the workpiece shaft is time-consuming and labor-intensive, which affects production efficiency

Moreover, the axial runout of the front end surface of the workpiece shaft and the parallel difference between the front and rear end surfaces of the positioning ring will generate cumulative errors, which will be reflected on the front end surface of the positioning ring, causing the axial runout of the front end surface of the positioning ring to be out of tolerance
