Double-station steel bar submerged arc stud automatic welding equipment

The invention discloses double-station steel bar submerged arc stud automatic welding equipment which comprises a servo truss module, a steel bar submerged arc stud welding gun, a servo sliding table and a welding flux automatic conveying and recycling device. The servo truss module is provided with a transverse moving mechanism and a vertical moving mechanism; the steel bar submerged arc stud welding gun is arranged on the servo truss module and can move in the vertical plane in the cross direction under the cooperation of the transverse moving mechanism and the vertical moving mechanism. The servo sliding table is arranged below the steel bar submerged arc stud welding gun and can move in the direction perpendicular to the vertical face. And the automatic welding flux conveying and recycling device is used for conveying welding flux to a steel bar welding point during welding and recycling the unmelted welding flux after the welding of the steel plate to be welded is finished. The equipment is high in autom
