In some embodiments, the rear clamping rotation assembly 63 includes a clamping end 631 and a clamping drive unit for driving the clamping end 631 closer to or away from the front clamping assembly 62 to clamp the hard and brittle bar stock 8. Thus, in this embodiment, the front clamping assembly 62 and the rear clamping rotating assembly 63 are fixed at the bottom of the clamping frame 61, and are not fixed, and the clamping driving unit can drive the clamping end 631 to extend and retract, so as to clamp the hard and brittle bar 8.

In this embodiment, the principle of the material clamping device 6 is as follows: in the using process, the hard and brittle bar 8 is conveyed to the position below the material clamping device 6 through the feeding device 4, and the material clamping device 6 clamps the hard and brittle bar 8 through the rear clamping rotating assembly 63 to complete clamping; the sliding driving unit 762 drives the clamping rack 61 to move on the upper rack 65, and the grinding device 7 processes two surfaces of the hard and brittle bar 8; after the processing is completed, the sliding driving unit 762 drives the clamping rack 61 to move backwards, the rear clamping rotating assembly 63 drives the hard and brittle bar 8 to rotate 90 degrees around the axial direction, the clamping rack 61 continues to move forwards, the grinding device 7 processes the other two surfaces of the hard and brittle bar 8, and after the processing is completed, the clamping device 6 places the hard and brittle bar 8 on the material receiving mechanism of the feeding device 4.

It should be noted that, although the above embodiments have been described herein, the scope of the present invention is not limited thereby. Therefore, based on the innovative concept of the present invention, the changes and modifications of the embodiments described herein, or the equivalent structure or equivalent process changes made by the contents of the specification and the drawings of the present invention, directly or indirectly apply the above technical solutions to other related technical fields, all included in the scope of the present invention.
