There is not enough extrusion force to keep the position of the welded parts stable, which may cause uneven welds and affect the welding quality and structural strength. There is a lack of effective extrusion fixation measures, and the welded parts may shake or vibrate during the welding process, which will bring difficulties to the welding operation.

When the grinding wheel 24 grinds the welding part of the weldment, when the welding part is higher than the position of the grinding wheel 24, the grinding wheel 24 squeezes the first spring 21, so that the grinding wheel 24 can better fit the welding part. When the grinding is completed, the external power supplies of the second servo motor 17 and the grinding wheel 24 are turned off, and then the external power supply of the cylinder 15 is turned on. At this time, the cylinder 15 lifts the height of the third bracket 16 to complete the work.
