[0002] In the traditional steel pipe welding process, the operator needs to hold the welding gun to weld along the circumferential welding seam of the steel pipe, which puts forward higher requirements for the experience of the welder. Due to the poor stability of holding with both hands, it consumes a lot of physical strength. Moreover, the circular welding seam has high requirements on the stability of the welding gun, which makes the welding efficiency of steel pipes low, and consumes a lot of physical strength for the operators. At the same time, the welding quality is uneven.

Abstract
The invention discloses a steel pipe welding device. The welding device comprises a shell, a welding mechanism and a clamping mechanism, wherein a rotary cylinder is arranged in the shell, the weldingmechanism is arranged on the rotary cylinder and comprises a set of welding guns which are oppositely arranged, the welding guns are fixedly connected with lifting frames, sliding groove plates are embedded in the upper ends of the lifting frames, the rotary cylinder is fixedly connected to the inner sides of the sliding groove plates, the rotary cylinder is fixedly sleeved with a gear ring, thegear ring is meshed with a driving gear, and the driving gear is fixedly connected with a driving motor. According to the welding device, by arranging a rotating structure comprising the rotating cylinder, the gear ring and the driving gear, a steel pipe is annularly welded, and compared with manual welding, the efficiency is high, and the quality is good; by arranging the sliding groove plates, lead screws, rotating wheels and the lifting frames, the height of the welding guns is conveniently adjusted, welding of steel pipes of different diameter specifications is achieved, and adaptability is good; and by arranging clamping plates, two-way lead screws, the double-shaft motor and supporting rollers, the levelness and stability during steel pipe welding are improved.
Description
technical field [0001] The invention relates to the field of welding, in particular to a steel pipe welding device. Background technique [0002] In the traditional steel pipe welding process, the operator needs to hold the welding torch to weld along the circumferential welding seam of the steel pipe, which puts forward higher requirements for the experience of the welder. Due to the poor stability of holding with both hands, it consumes a lot of physical strength. Moreover, the annular welding seam has higher requirements on the stability of the welding torch, so that the efficiency of steel pipe welding is relatively low, and the physical strength of the operator is greatly consumed. At the same time, the welding quality is uneven. Contents of the invention [0003] The object of the present invention is to provide a steel pipe welding device to solve the problems raised in the above-mentioned background technology. [0004] To achieve the above object, the present inv...
