Production line of excavator platform

The utility model provides a production line of an excavator platform. The production line comprises an assembly station, a spot welding station, a full welding station and a reversible deformation station, the excavator platform is composed of two side plates and a main platform. The side plates and the main platform are subjected to assembly operation through the assembly station, then the side plates are manually assembled on the two sides of the main platform through the material frame of the second assembly station, the side plates are conveyed to the spot welding station through the crane, and finally the full welding station and the anti-deformation station cooperate to conduct reverse pressing in the welding process of the excavator platform so as to conduct pre-deformation. The problem that the welding precision is poor due to the fact that the side plates deform relative to the main platform in the full-length welding process is avoided, especially through early-stage pre-deformation treatment of th
