When grinding is required, the automatic telescopic rod 2013 is started to push the mounting frame 2014 and the grinding disc 2015, so that the grinding disc 201 5 is close to the welding surface of the guide wheel. By arranging a third motor inside the mounting frame 2014, it is convenient to drive the grinding disc 2015 to rotate and grind the welding position of the guide wheel. When it is necessary to weld and grind the other side of the guide wheel, the positioning plate 1002 is pushed upward by the cylinder 1009, so that the guide wheel on the positioning plate 1002 is located between a pair of rotating disks 1006. By starting the hydraulic rod 1003, when it works, it is convenient to push the fixing frame 1004 to move toward the center of the workbench 1001, so as to clamp and fix the guide wheel. At this time, the cylinder 1009 shrinks and returns to its original position. By starting the first motor 1007, the rotating disk 1006 is rotated, so that the other rotating disk 1006 is synchronously rotated when connected to the guide wheel, so as to realize the flipping of the guide wheel. After the flipping of the guide wheel is completed, the positioning plate 1002 is pushed upward by the cylinder 1009 to place the flipped guide wheel, so as to continue the welding and grinding work.
