Embodiment Construction
[0019] The specific implementation manner of the present invention will be described in detail below in conjunction with the accompanying drawings and preferred embodiments.
[0020] Such as Figure 1~3 As shown, the present invention provides a welding device for box-type structural parts, including two hollow cylindrical support members 2 arranged on the tugboat group 1, and these two cylindrical support members 2 are respectively sleeved on The two ends of the box-type structural part 3 to be welded, the shape of the hollow part is consistent with the cross-sectional shape of the box-type structural part 3 to be welded, and the tugboat group 1 drives the cylindrical support part 2 to rotate around its center of circle, thereby driving the setting The box-type structural part 3 to be welded therein rotates to complete the welding of each welding position on the box-type structural part 3 to be welded. In this way, when flat-welding large-scale box-type structural parts, it ...

The invention belongs to the technical field of welding equipment, and discloses a welding device for a box type structural member. The welding device comprises two hollow cylindrical supports arranged on a dragging wheel set, wherein the two cylindrical supports respectively sleeve the two ends of a box type structural member to be welded, the shapes of the hollow parts of the cylindrical supports are consistent with the shape of the cross section of the box type structural member to be welded, and the cylindrical supports are driven to rotate around the circle center by the dragging wheel set, so that the box type structural member to be welded in the cylindrical supports is driven to rotate and the welding of each welding position on the box type structural member to be welded is completed. The welding device provided by the invention does not need to hoist and overturn the box type structural member and only needs to drive the cylindrical supports to rotate by means of the draggingwheel set, the deformation of the structural member in an overturning process is avoided, the manpower and material resources are saved, meanwhile, the vertical welding and the overhead welding are converted into flat welding, and the welding efficiency and the welding quality are improved.
Description
technical field [0001] The invention relates to the technical field of welding equipment, in particular to a welding device and a welding method for box-type structural parts. Background technique [0002] In general, large cuboid components such as box-type structural parts are manufactured by splicing and forming first, and then welding. In the welding of box-type components, vertical welding, overhead welding and other methods that are difficult to weld or have low welding efficiency are often used, which cannot guarantee the overall welding quality of the components. In order to change the welding method, the components need to be lifted and turned over repeatedly. Generally, wire ropes and cranes are used to turn over, and it requires the cooperation of multiple people, which consumes manpower. During the turning process, uneven force may cause deformation of components and affect the overall forming effect. Contents of the invention [0003] The invention provides a...
