Therefore, this utility model proposes a surface fine grinding device for processing self-lubricating bearings to solve the problems existing in the prior art. Utility Model Content

[0028] A detection camera 33 is installed on the lower front side of the adjustment plate 3. The detection camera is electrically connected to the external main controller and is used to detect the grinding condition of the bearing ring. Specifically, image processing technology is used to identify whether the grinding condition of the bearing ring is qualified.

[0029] When using this self-lubricating bearing surface polishing device, the material is first transported via a loading and unloading conveyor belt. When the outer ring of the bearing is conveyed to a position flush with the movable seat, the sensor on the conveyor belt detects this and controls it to stop. Simultaneously, the drive screw rotates, moving the movable seat directly above the bearing ring to be processed. At this point, another set of grippers is positioned directly above the processed bearing ring. Then, a multi-segment telescopic rod moves the grippers downward, simultaneously gripping both the bearing ring to be processed and the processed bearing ring. Subsequently, the rotating holding mechanism releases the processed bearing ring, which is then lifted by the multi-segment telescopic rod. Finally, the drive screw moves the movable seat, moving the bearing ring to be processed directly above the rotating holding mechanism. At this point, the processed bearing ring is above the unloading conveyor belt of the loading and unloading conveyor belt, and the multi-segment telescopic rod moves the grippers downward to release and reset the material. The bearing ring to be processed is then clamped and fixed by the rotating holding mechanism, completing the synchronous loading and unloading of the bearing ring.

[0030] During clamping, the bearing ring is first fixed from the inside by the external support clamping mechanism. Then, fine grinding is performed. First, the distance between the adjusting block and the upper side of the inverted L-shaped fixing plate is adjusted according to the width of the bearing ring. Then, the horizontal telescopic rod drives the adjustable grinding block mechanism to approach the bearing ring. At the same time, the bearing ring is driven to rotate at high speed by the rotating frame mechanism to achieve fine grinding of the outer surface and the upper and lower surfaces of the bearing ring.

[0031] After the outer and upper / lower surfaces of the bearing ring are finely polished, the bearing ring is clamped by an external clamping plate. Then, the adjusting block is adjusted to the highest position and locked. Subsequently, the lifting and adjusting mechanism drives the outer side of the inverted L-shaped fixing plate on the lower side of the adjusting plate to insert into the inner side of the bearing ring and close to the inner surface of the bearing ring. Finally, the rotary motor drives the whole thing to rotate, which can achieve the fine polishing of the inner surface of the bearing ring. After polishing, the inspection camera checks the fine polishing of the bearing ring and determines whether it is qualified.
