[0041] The cross bar 6 is provided with a slide groove 12, the second servo electric cylinder 11 is installed in the slide groove 12, and the slider 8 is slidably connected in the slide groove 12, which has a guiding effect on the sliding of the slider 8, thereby ensuring the stable movement of the position of the welding gun 10;

[0042] A guide disc 13 is provided on the slider 8, and a support plate 14 is fixedly connected to the output end of the second stepper motor 9. The support plate 14 is clamped in the guide disc 13, and the welding gun 10 is fixedly connected to the support plate 14; an annular groove 15 is provided on the side wall of the guide disc 13, and the bent ends 16 at both ends of the support plate 14 are clamped in the annular groove 15, which has a guiding and supporting effect on the rotation of the welding gun 10, thereby ensuring that the welding gun 10 rotates smoothly.

[0043] Working principle: First, fix the base 2 in the middle of the coal mill, and multiple grinding rollers are located around the base 2. The entire welding device is built based on the base 2. Secondly, the welding gun 10 performs surfacing welding on one of the grinding rollers. Then, the first stepper motor 3 rotates to drive the driving gear 4 to rotate. Under the meshing action of the driving gear 4 and the gear plate 1, the gear plate 1 rotates as a whole to change the direction of the welding gun 10. The first servo electric cylinder 7 telescopically drives the cross bar 6 to rise and fall along the vertical bar 5 to adjust the height of the welding gun 10. The second servo electric cylinder 11 telescopically drives the slider 8 to slide along the slide groove 12 to adjust the horizontal position of the welding gun 10. The second stepper motor 9 rotates to drive the support plate 14 to rotate. The annular groove 15 has a guiding and supporting effect on the bent end 16 of the support plate 14, thereby driving the welding gun 10 on the support plate 14 to produce an angle change, so that the welding gun 10 points to another grinding roller to adapt to the optimal surfacing position of the grinding roller. Finally, the welding gun 10 performs surfacing welding on the grinding roller.
