[0029] The present invention will now be further described with reference to the accompanying drawings.

[0030] like Figures 1 to 12 As shown, a grinding wheel sharpening machine includes an outer cylindrical surface sharpening device 1, a top edge sharpening device 2, a feeding device 5, a rotating device 4, a clamping device 3, and a feeding device 6 and a receiving device 7 located at both ends of the feeding device 5, all mounted on a frame. The outer cylindrical surface sharpening device 1 is used for sharpening the outer cylindrical surface of the grinding wheel. The top edge sharpening device 2 is located on one side of the outer cylindrical surface sharpening device 1 and is arranged side by side with the outer cylindrical surface sharpening device 1, and is used for sharpening the top edge of the grinding wheel. The feeding device 5 is arranged opposite to the outer cylindrical surface sharpening device 1 and the top edge sharpening device 2. The rotating device 4 is mounted on the machine frame. The machine is mounted on a frame and has two rotating devices 4, which are respectively located between the feeding device 5 and the outer circular surface sharpening device 1 and the top edge sharpening device 2. The clamping device 3 is mounted on the frame and is located above the rotating device 4, and corresponds to the rotating device 4 one by one. The clamping device 3 is used to press the grinding wheel onto the rotating device 4. The feeding device 6 and the receiving device 7 have the same structure and are used to stack the grinding wheel to be sharpened and the sharpened grinding wheel, respectively. The feeding device 5 is used to switch the grinding wheel between the feeding device 6, the outer circular surface sharpening device 1, the top edge sharpening device 2 and the receiving device 7.

[0031] The feeding device 5 first picks up the grinding wheel from the feeding device 6, and then feeds the grinding wheel into a rotating device 4 that is opposite to the outer circular surface sharpening device 1. Then, the pressing device 3 above the rotating device 4 presses the grinding wheel onto the rotating device 4. The rotating device 4 starts and drives the grinding wheel to rotate. Then, the outer circular surface sharpening device 1 starts to grind and sharpen the outer circular surface of the grinding wheel. After the outer surface of the grinding wheel is sharpened, the rotating device 4 stops rotating. The feeding device 5 moves the sharpened grinding wheel to another rotating device 4, which is opposite to the top-edge sharpening device 2. Then, the clamping device 3 clamps the grinding wheel onto the rotating device 4. At the same time, the feeding device 5 also moves the sharpened grinding wheel on the feeding device 6 to the rotating device 4, which is opposite to the outer surface sharpening device 1, and moves the top-edge sharpened grinding wheel on the rotating device 4, which is opposite to the top-edge sharpening device 2, to the receiving device 7.
