The mounting seat 4 is mounted on the free end of the robotic arm, and the robotic arm can be controlled by a numerical control device to move back and forth on the rows of holes on the workpiece 1, thereby accelerating the processing speed of the grinding piece on the rows of holes and maintaining the stability of the grinding piece 7 when processing the above structure, thereby avoiding that the axial centers of individual axial holes in the rows of holes are not on the same straight line after subsequent processing is completed. A mounting channel with a circular cross-section is provided in the mounting seat 4, and the annular rotating cylinder 5 is installed in the mounting channel, and the length of the rotating cylinder 5 is greater than the length of the mounting channel. The grinding piece 7 is installed in the rotating cylinder 5 by means of a buckle and bolts, which is convenient for later disassembly and maintenance. The mounting seat 4 is provided with a driving assembly for driving the rotating cylinder 5 to rotate, so that the grinding piece 7 can make a circular motion on the mounting seat 4, so as to process the axial hole to be ground and improve the processing accuracy of the inner surface of the axial hole.

[0027] Preferably, the robotic arm can be adjusted at multiple angles in space, and the robotic arm is prior art, which is not shown in the figure.

[0028] In some technical solutions of the present invention, the drive assembly includes a second drive motor 14 installed in the mounting base 4, and a long gear 16 is provided on the output end of the second drive motor 14. A transmission gear 15 meshing with the long gear 16 is sleeved on the outer wall of the rotating cylinder 5. In this way, after the rotating cylinder 5 extends out of the mounting channel, the set transmission gear 15 and the long gear 16 can also be engaged, so that the second drive motor 14 can continuously transmit the power it outputs to the rotating cylinder 5, ensuring that the grinding part 7 can continuously process the shaft hole to be ground.

[0029] In some technical solutions of the present invention, the grinding part 7 includes a grinding roller 10 installed in the rotating cylinder 5, and a drilling tool 8 is provided at the end of the grinding roller 10 facing away from the rotating cylinder 5.
