The long rib plate 4 is placed on the front side of the processing table 1, and the left end of the long rib plate 4 is placed on the front side of the short rib plate 5. The orientation of the long rib plate 4 is positioned by the positioning block 2 at the lower part and the right part of the front side of the processing table 1. After the long rib plate 4 is placed at the designated position and clamped by the clamping mechanism, the robot loosens the long rib plate 4 and takes the round steel 6. The robot places the round steel 6 on the front side of the long rib plate 4 and the short rib plate 5 with the left side higher and the right side lower, and the round steel 6 is clamped by the clamping mechanism for positioning. The robot loosens the round steel 6, and the loading is completed. Finally, welding can be performed by the welding robot. The utility model fixes the relative positions of the short rib plate 5, the long rib plate 4 and the round steel 6 by the positioning block 2 and the clamping mechanism, which can facilitate subsequent welding. The use of the robot can greatly reduce the labor intensity of the operators and improve the welding quality.
