The invention relates to a rod piece
welding machine, particularly relates to an automatic
welding device for a large rod piece box beam, and belongs to the technical field of
mechanical devices. The
machine comprises a walking mechanism, a door frame, a
welding arm lifting mechanism, a welding seam
servo tracking mechanism, a welding gun three-dimensional adjusting mechanism, an operation platform, a carrier platform, a welding flux conveying recycling
system and the like. The door frame is installed on the walking mechanism, the welding arm lifting mechanism is installed on the door frame, the welding seam
servo tracking mechanism is installed on the welding arm lifting mechanism, the welding gun three-dimensional adjusting mechanism is arranged on the welding seam tracking mechanism, the operation platform is installed on the welding arm lifting mechanism, the carrier platform is installed on the door frame, and the welding flux conveying recycling
system is installed on the welding arm lifting mechanism. The rod piece welding
machine is simple, compact and reasonable in structure and capable of accurately and quickly achieving welding of different rod pieces and different box beams, greatly reduces labor intensity of workers, and is high in
automation degree, high in welding accuracy, low in cost and convenient and flexible to use.
