Problems solved by technology
However, most of the turning devices in the prior art adopt the middle fulcrum structure, the distance between the fulcrum and the ground is too large, the operation is difficult and unsafe, or the turning device part is set below the ground by digging a hole on the ground, which is inconvenient for installation and adjustment. When welding the two sides of the plate unit, it needs to be flipped in two directions, and the angle adjustment and control are inconvenient, and the welding efficiency is low

The invention discloses an overturning device for plate unit ship type welding and a welding tool. The overturning device comprises at least one group of lifting mechanisms. Each group of lifting mechanisms comprises at least two lifting mechanisms. Each lifting mechanism is provided with a fulcrum. At least two lifting mechanisms of each group of lifting mechanisms are arranged in parallel and are aligned with the fulcrums. Each group of lifting mechanisms can drive positioner platforms for plate unit ship type welding to rotate around the fulcrums. The overturning device for plate unit shiptype welding and the welding tool are simple in structure, small in occupied space, convenient to operate, capable of adjusting the angle conveniently, convenient to control, safe and reliable, and high in welding efficiency.
Description
technical field [0001] The invention relates to a welding device, in particular to an overturning device and a welding tool for ship-shaped welding of plate units. Background technique [0002] In the welding of plate units, for the longitudinal seam welding between panels and ribs (such as U rib reinforcement, opening reinforcement, bulb flat steel reinforcement, T-shaped reinforcement, etc.), in order to ensure uniform weld leg size, avoid The weld meat of flat fillet welds collapses to improve productivity. Generally, boat welding is used, and the panel is turned from a horizontal state to an angle required for welding by a turning device, such as rotating 45° to an inclined state for welding. At the same time, due to the large welding deformation and residual stress, the panel will be warped and deformed during the welding process. In the prior art, anti-deformation devices are also used in boat welding. However, most of the turning devices in the prior art adopt the mi...
