The invention belongs to the technical field of welding devices, and particularly relates to a welding device for a longitudinal seam of a barrel body. The welding device comprises a barrel body fixing unit and a longitudinal seam welding unit. The barrel body fixing unit comprises a base. An arc-shaped groove used for containing the barrel body is formed in the middle portion of the base. An arc-shaped protruding block matched with the arc-shaped groove is arranged above the base. A long-strip-shaped inner supporting plate is arranged above the arc-shaped protruding block in the axial direction of the arc-shaped groove. A hydraulic oil cylinder driving the base to move up and down is arranged at the bottom of the base. The longitudinal seam welding unit comprises a machine frame. A lead screw is horizontally installed on the machine frame and is driven by a motor. A foundation support is arranged on the lead screw and provided with a vertical slide rail. A welding gun installation base is arranged on the vertical slide rail. A welding gun is installed on the welding gun installation base. According to the welding device, by ensuring the stability of the barrel body in the welding process, positioning of the welding seam is more accurate, the welding seam is more uniform, and the consistency of final products is better.
Description
Technical field [0001] The invention belongs to the technical field of welding equipment, and particularly relates to a barrel longitudinal seam welding device. Background technique [0002] In the process of making steel drums, firstly, the sheared steel plate needs to be rolled out of the shape of the drum body by a rolling machine, then spot welding is performed at the joints, and then longitudinal seam welding is performed to obtain a complete cylindrical shape. Of the barrel. For large barrels, the traditional manual welding method is not only low production efficiency and backward production technology, but also has the problems of inaccurate weld positioning and uneven welds, resulting in uneven quality of the final product and consistent barrels. Poor sex. [0003] Therefore, it is necessary to develop and design a barrel longitudinal seam welding device that can fix the barrel body, accurately locate the weld seam during the welding process, and the weld seam is uniform....
