[0025] like Figs. 1 to 3 As shown, this utility model includes an angle adjustment mechanism, a vertical feed mechanism, and a grinding motor 16. The angle adjustment mechanism includes a mounting base plate 1, an arc guide rail 2, angle adjustment rollers 11, an adjustment plate 12, an angle adjustment servo motor 20, and a gear ring 14. The arc guide rail 2 and the gear ring 14 are mounted on the mounting base plate 1. Four angle adjustment rollers 11 are mounted on the adjustment plate 12. The angle adjustment rollers 11 and the arc guide rail 2 are connected in a rolling manner to support, limit, and guide the adjustment plate 12. The angle adjustment servo motor 20 is mounted on the side of the adjustment plate 12. The output shaft of the angle adjustment servo motor 20 is connected to an angle adjustment gear, and the angle adjustment gear meshes with the gear ring 14.

[0026] The vertical feed mechanism includes vertical moving rollers 3, vertical sliding block 15, vertical servo motor 10, lead screw 13, and lead screw nut 17. A V-shaped guide rail 22 is provided on the vertical sliding block 15. Four vertical moving rollers 3 are mounted on the adjustment plate 12. The vertical moving rollers 3 roll in cooperation with the V-shaped guide rail 22, positioning and guiding the vertical sliding block 15. The output shaft of the vertical servo motor 10 is connected to the lead screw 13, and the lead screw 13 is threadedly connected to the lead screw nut 17. The lead screw nut 17 is fixedly connected to the vertical sliding block 15. A grinding motor 16 is mounted on one side of the vertical sliding block 15, and the output shaft of the grinding motor 16 is connected to a grinding wheel 19.

[0027] In this embodiment, a lead screw mounting seat 8 is installed on the upper part of the adjusting plate 12, a vertical servo motor 10 is installed on the upper part of the lead screw mounting seat 8, and a lead screw 13 is installed on the lower part of the lead screw mounting seat 8. The output shaft of the vertical servo motor 10 is connected to a vertical planetary reducer 9. The output shaft of the vertical planetary reducer 9 is connected to the top of the lead screw 13 through a coupling 7. The lower part of the coupling 7 is connected to the lead screw 13 through a round nut 6. The upper sidewall of the lead screw 13 is installed in the lead screw mounting seat 8 through a self-aligning roller bearing 5. A bearing cover 4 is provided on the self-aligning roller bearing 5.
