In the embodiment, the principle of the clamping device 6 is that in the use process, the hard and brittle bar 8 is transported to the lower side of the clamping device 6 through the feeding device 4, the clamping device 6 clamps the hard and brittle bar 8 through the rear clamping rotating assembly 63, after clamping is completed, the sliding driving unit 762 drives the clamping frame 61 to move on the upper frame 65, the grinding device 7 processes two sides of the hard and brittle bar 8, after processing is completed, the sliding driving unit 762 drives the clamping frame 61 to retreat, the rear clamping rotating assembly 63 drives the hard and brittle bar 8 to rotate 90 degrees around the axial direction, the clamping frame 61 continues to move forwards, the grinding device 7 processes the other two sides of the hard and brittle bar 8, and after processing is completed, the clamping device 6 places the hard and brittle bar 8 on a receiving mechanism of the feeding device 4.

It should be noted that, although the foregoing embodiments have been described herein, the scope of the present invention is not limited thereby. Therefore, based on the innovative concepts of the present invention, alterations and modifications to the embodiments described herein, or equivalent structures or equivalent flow transformations made by the present description and drawings, apply the above technical solution, directly or indirectly, to other relevant technical fields, all of which are included in the scope of the invention.
