[0002] Bearings are an important component in contemporary mechanical equipment. The main function of bearings is to support mechanical rotating bodies, reduce the friction coefficient of mechanical rotating bodies during movement, and ensure the rotation accuracy of mechanical rotating bodies. In order to ensure the surface accuracy of bearings during the processing, bearings need to be polished. In order to ensure the stability of the polishing process, bearings need to be fixed;

The clamping device for bearing processing of the utility model limits the position of the driving rod by arranging a limit block and a limit shaft. When the driving rod moves with the movement of the output end of the electric push rod, the bottom end of the driving rod will not be offset, so that the driving rod can drive the gear teeth to move more stably, and more effectively ensure the stability of the meshing between the gear teeth and the transmission gear, thereby improving the stability of the four groups of clamping blocks in fixing the bearings, and under the action of the slider and the slide groove, the transmission shaft can drive the clamping blocks to move more stably and accurately, further improving the stability of the clamping blocks in fixing the bearings.

[0032] Working principle: First, by setting the mounting plate 2, it is convenient to fix the bottom plate 1 on the upper end of the bearing processing equipment through the fixing bolts 3, and the rotating rod 6 on the right side of the supporting plate 4 is fixedly used with the connecting rod 81, so that the clamping ring 82 is fixedly connected to the top of the bottom plate 1. Then, when it is necessary to clamp the bearing, the fixing block 85 is pulled outward, so that the fixing block 85 drives the push rod 84 to move up along the active cavity 811 on the inner wall of the sleeve 83. Further, the push rod 84 drives the clamping plate 86 to move up synchronously at the same time, so that it is close to the inner side of the clamping ring 82.

At this time, the micro-telescopic rod 74 is in a retracted state, and under the setting of the fixed plate 73, the bearing moves simultaneously on the inner side of the fixed plate 73, so that the bearing moves out of the clamping ring 82, and then the clamping plate 75 is driven away from the outer side of the bearing by the micro-telescopic rod 74, thereby releasing the fixed state of the bearing. At this time, the staff can take out the bearing from the inside of the clamping plate 75, which is convenient and simple to operate. The above is the working process of the entire device, and the contents not described in detail in this specification belong to the existing technology known to professional and technical personnel in this field.
