The drive gear 101 is also located on the side of the cutting and grinding tool 12, and the rotary drive motor 10 is connected to the cutting and grinding tool 12 through the drive gear 101.

[0037] In this embodiment, the cutting and grinding tool 12 includes a central shaft 121 passing through the hollow frame 111, and a cutting blade 122 and a hexagonal positioning column 123 are integrally provided at both ends of the hollow frame 111, and the cutting blade 122 and the hexagonal positioning column 123 are respectively located on both sides of the hollow frame 111.

The outer rings of the two positioning bearings 124 are interference fit with the mounting holes 112 on both sides of the hollow frame 111 , and the inner rings are interference fit with the central shaft 121 .

[0039] In this embodiment, a driven bevel gear 125 is further provided between the two positioning bearings 124 , and the driven bevel gear 125 is interference-fitted with the central shaft 121 via a flat key;

[0040] The driving gear 101 is located on the side of the driven bevel gear 125, and the driving gear 101 and the driven bevel gear 125 are meshed with each other.

[0041] In this embodiment, the outer side of the hexagonal positioning column 123 is sleeved with a grinding sleeve 8, and a positioning hole 81 corresponding to the hexagonal positioning column 123 is opened in the grinding sleeve 8.

The locking bolt 83 is loosened and the baffle 82 is removed, making it convenient for workers to replace the grinding sleeve 8.

[0046] The working principle of the present invention is as follows: when in use, the workpiece is first fixed to the workbench 6 by a clamp, and then the workpiece moving module 5 drives the workpiece to move to a suitable position, the lifting module 3 drives the slide frame 4 to move downward, so that the cutting knife 122 moves closer to the workpiece, and the rotary drive motor 10 drives the central shaft 121 to rotate through the transmission connection between the driving gear 101 and the driven bevel gear 125. The central shaft 121 simultaneously drives the cutting knife 122 and the hexagonal positioning column 123 to rotate, and the rotating cutting knife 122 cuts the workpiece. After the cutting is completed, the lifting module 3 drives the cutting knife 122 away from the workpiece through the slide frame 4, and at the same time, the workpiece is flipped. The servo motor 9 drives the hollow frame 111 to rotate through the hollow shaft 113, rotates the central shaft 121 in the hollow frame 111, and rotates the hexagonal positioning column 123 on the upper part of the hollow frame 111 to the lower part of the hollow frame 111.

There is no need to spend a long time looking for a grinding component of suitable size, and cutting and grinding only require changing the position of the cutting and grinding tool 12, which improves the efficiency of tool replacement and thus increases processing efficiency.
