Description

Technical Field

[0001] The present invention relates to the technical field of welding equipment, and particularly relates to a box body welding and turning device. Background Art

[0002] Since there are a large number of box body structures in equipment such as large boilers and heat exchangers, the box bodies are relatively large in volume and there are a large number of pipelines in the box body structures. To improve the welding qualification rate of workpieces and save labor at the same time, they are usually placed on a welding workbench during welding.

[0003] In the prior art, the traditional welding workbench usually has a planar structure. After welding is completed, it needs to be turned over by an electric overhead crane, which has potential safety hazards. Moreover, it cannot realize the turning action during the box body welding process and cannot meet the ship-shaped welding angle of the box body welding, greatly affecting the work efficiency and increasing the production cost; the existing welding workbench is only applicable to box bodies of a single size, and multiple sets of equipment need to be purchased for welding box bodies of multiple sizes, increasing the cost; when the existing turning workbench is fixed after moving, it mostly uses shaft clamps and screw pairs for fixation, increasing the weight of the equipment and requiring a large force during fixation, which is not suitable for operators with relatively small strength. Summary of the Invention

[0004] To solve the above problems, the purpose of the present invention is to provide a box body welding and turning device, which sets claw to fix the welded box body and fixes it through a two-way cylinder, intelligently fixes the box body, sets a moving adjustment mechanism and a locking mechanism, is compatible with box bodies of various sizes, improves compatibility, and is convenient and labor-saving for locking and unlocking.
