The invention discloses an auxiliary welding device for a rectangular three-dimensional frame and an application method thereof, belonging to the field of welding equipment. The auxiliary welding device of the present invention includes a bracket and a turret mounted on the bracket for rotation. A set of cross-bar adjustment and clamping mechanisms are respectively arranged on each of the four sides of the turret. Each set of cross-bar adjustment and clamping mechanisms is equipped with a height adjustment mechanism The vertical bar adjustment clamping mechanism uses the cross bar adjustment clamping mechanism to assemble and fix the top and bottom rectangular frames of the rectangular three-dimensional frame, and at the same time uses the vertical bar adjustment clamping mechanism on each set of cross bar adjustment clamping mechanisms to fix the frame The vertical bar is used to assemble and fix the vertical bar of the frame with the top and bottom rectangular frames, so that the assembly accuracy of the rectangular three-dimensional frame is high, the assembly and positioning are convenient, and the welding efficiency and product qualification rate are greatly improved; at the same time, the horizontal bar adjusts the clamping mechanism and the vertical bar Adjusting the clamping mechanism is flexible and convenient for the clamping operation of the frame bar, and the clamping is stable and reliable, which facilitates the removal of the welded rectangular three-dimensional frame.
Description
technical field [0001] The invention relates to a welding device, in particular to an auxiliary welding device for a rectangular three-dimensional frame and a method for using the same. Background technique [0002] In the prior art, the rectangular three-dimensional frame structure is widely used, for example, it is used to support the frame of a product such as a frame body or an elevator car, and the like. Existing rectangular three-dimensional frames mainly include spliced frames and welded frames. Spliced frames are usually connected by profile rods through connectors, which are more convenient for disassembly and assembly, but the strength and integrity of the frame structure are not as good as welded frames. However, welded rectangular frames have higher requirements on welding quality. Welding stress deformation is the main cause of deformation defects in welded frames. At present, many rectangular frames are welded by manual frame welding, and welding errors and...
