Zusammenfassung: | The invention relates to an automatic submerged-arc welding device for a large end face. A base 1 is fixed to a ground foundation, wherein a servo motor 5 is mounted on the base 1; a speed reducer 6 is mounted at the output end of the servo motor 5; a gear 18 is mounted on the speed reducer 6; the gear 18 is meshed with a gear 19 fixed to a rotating shaft 9; a bearing pedestal 8 is fixed to the upper end of the base 1; the rotating shaft 9 is mounted on the bearing pedestal 8; and a cantilever 10 and the rotating shaft 9 are fixed at the crossed position. According to the automatic submerged-arc welding device for the large end face, the mode that a collecting ring is matched with an electric brush to supply power to a submerged-arc welding machine is adopted, the problem that power linesare wound when full-circle welding line welding is carried out is solved, the labor cost of welding is reduced, the welding efficiency is improved, the high rotation precision of the rotating shaft can be guaranteed, and ther |
