Automatic welding device and production line thereof

The invention provides an automatic welding device. The automatic welding device comprises a welding gun assembly, a feeding assembly, a bracket and a driving part. The feeding assembly is connected to the bracket. The feeding assembly abuts against a weld joint of a to-be-welded piece. The driving part is arranged at the bracket. The welding gun assembly is provided with a welding position closeto the weld joint and a temper position away from the weld joint under driving of the driving part. The welding gun assembly is driven to complete the welding process automatically through the drivingpart. Machine welding replaces traditional manual welding, and production efficiency is improved. 本发明提供种自动焊接装置包括焊枪组件及送料组件，支架，其上连接有送料组件，所述送料组件抵接于待焊件的焊缝处；驱动部组，设置在所述支架上；所述焊枪组件在所述驱动部组的驱动作用下具有靠近所述焊缝的焊接位置和远离所述焊缝的回火位置。本发明通过驱动部组自动驱动所述焊枪组件完成焊接过程，机器焊接取代了传统的人力焊接，提高了生产效率。
