Description

Technical Field

[0001] The utility model belongs to the technical field of fixing devices, in particular to a workpiece fixing device for composite welding processing. Background Art

[0002] Composite welding is a welding technology that combines two or more different welding methods or materials to achieve better welding results and performance. This technology can give full play to the advantages of various welding methods while overcoming their respective shortcomings, thereby achieving higher quality and more efficient welding. The shapes of the workpieces to be processed in composite welding are different. Before welding, in order to ensure that the position of the workpiece does not shift during the welding process, most of the workpieces need to be fixed before welding. Most common fixing devices are flat clamping fixing structures, which have poor clamping effects when clamping and fixing arc-shaped workpieces, which may cause offsets during the welding process. The solution to this defect is to replace the arc clamping structure. However, switching between flat clamping and arc clamping usually requires cumbersome disassembly and assembly, which will generate unnecessary labor and reduce the overall processing efficiency.

[0003] In summary, there are some problems in the use of the fixing device that cannot conveniently switch the clamping fixing structure, so it is hoped to propose a new structure to solve the above technical problems. Utility Model Content
