Description

A clamping device for bearing machining

Technical Field

The utility model relates to the technical field of bearing mechanical processing equipment, and specifically discloses a clamping device for bearing mechanical processing.

Background Art

The main function of the bearing is to support the mechanical rotating body to reduce the friction coefficient of the mechanical load of the equipment during the transmission design process. The bearing is a component that fixes and reduces the load friction coefficient during the development of mechanical transmission. When other parts on the shaft move relative to each other, the bearing can reduce the friction coefficient during power transmission and keep the center position of the shaft fixed. At present, in the production and manufacturing process of bearings, most of them need to perform multiple post-processing production processes such as drilling, grooving, fine grinding, and polishing. In order to ensure the processing accuracy of the bearing, a clamping device is often used to stably clamp the bearing to ensure the production quality of the bearing.

The utility model patent with authorization announcement number: CN219466116U discloses a clamping mechanism for bearing processing, including a workbench, a rotating mechanism is installed on the top of the workbench, a fixing mechanism is installed on the top of the rotating mechanism, and columns are fixedly installed at equal angles on the bottom of the workbench; the rotating mechanism includes a support plate located on the top of the workbench, a connecting rod is fixedly connected at equal angles to the bottom of the support plate, an outer ring is fixedly installed on the bottom end of the connecting rod, a fixing ring is fixedly installed on the top of the workbench, an outer groove is provided on the outer side of the fixing ring, and the fixing ring is rotatably connected to the outer ring through the outer groove.

In the disclosed patent technology, the bearing is fixed on the top of the support plate, and the support plate is driven by the rotating shaft to rotate under the drive of the motor, and the support plate is stably rotated through the cooperation between the connecting rod and the outer ring and the fixed ring and the outer groove, so as to facilitate the processing of the bearing. The clamping mechanism in the above-mentioned disclosed patent can only clamp the bearing and rotate it. In the actual bearing manufacturing process, the clamping mechanism needs to cooperate with multiple sets of equipment such as hole opening, grooving, fine grinding, and polishing. It often needs to be continuously rotated and multi-directional horizontal and vertical displacement to adapt to multi-angle and multi-position processing operations; it can be seen that the clamping mechanism in the above-mentioned disclosed patent is difficult to cooperate with other bearing processing equipment for precision operation, and the functional structure is relatively limited, resulting in poor operational flexibility, which greatly affects the processing and production efficiency of the bearing.
