The position distribution of the two groups of auxiliary protective plates (1107) is symmetrical about the central axis of the main protective plate (1105), and the overall material of the main protective plate (1105) and the auxiliary protective plate (1107) are transparent materials, and the outer wall of the operating port (1106) is provided with a fireproof cloth cover.

10. The method for using the excavator bucket welding device according to any one of claims 1 to 9, characterized in that: The following steps are involved: Step S1, when placing the bucket on the welding device for welding processing, in order to improve the conversion clamping effect of different positions of the bucket, when it is necessary to weld the two sides of the bucket, the upper and lower ends of the bucket are clamped and fixed, and when it is necessary to weld the top of the bucket, the two sides are clamped and fixed, the first servo motor (601) is turned on and the swing rod (602) is rotated to drive the sliding block (603) to slide along the inner wall of the limit groove (604) and the conversion groove (605), so that the sliding block (603) drives the clamping position of the clamping block (607) to change, and the second servo motor (1001) is turned on and the first threaded rod (1002) is rotated to drive the sliding frame (5) to slide along the inner wall of the slide groove (1003), so that the clamping block (607) clamps and fixes the two sides of the bucket, reduces the situation that the clamping block (607) blocks the area to be welded of the bucket, and improves the efficiency of the welding device for the bucket; Step S2, when it is necessary to clamp and fix the upper and lower ends of the bucket for welding, turn on the first servo motor (601) to drive the sliding block (603) to slide along the inner walls of the limit groove (604) and the conversion groove (605) through the rotation of the swing rod (602), so that under the movement of the sliding block (603), the clamping block (607) moves to the top of the bucket, and turn on the electric push rod (8) to drive the lifting box (4) to slide along the inner wall of the lifting groove (9), so that the anti-skid pad (608) is tightly fitted with the top of the bucket, so as to play the role of converting and fixing the top of the bucket; Step S3, when welding is performed on different positions of the bucket through the welding device, in order to improve the efficiency of the welding personnel in welding the bucket and to free the welding personnel from holding the protective plate, when the position of the protective plate needs to be adjusted, the knob (1102) is turned to drive the threaded slider (1103) to slide along the inner wall of the fixed groove (1104) through the rotation of the second threaded rod (1101). The sliding of the threaded slider (1103) drives the position of the main protective plate (1105) to move, and the welding gun is inserted into the operating port (1106) to perform a blocking welding operation on the bucket. The motor on the top of the main protective plate (1105) can be turned on to drive the auxiliary protective plate (1107) to flip, thereby achieving the effect of switching protection for the welding personnel on the side of the bucket.
