The cab frame is generally divided into left enclosure, right enclosure, front enclosure, rear enclosure and bottom plate assembly. The left enclosure and right enclosure are important components of the cab frame. There are generally two ways to make them: one is to make them without process equipment, which uses manual marking, proportional lofting, etc. to spot weld and position the parts that make up the side enclosure, and then weld them. Although the speed is fast, the processing accuracy and consistency are poor; the other is to design and make the machined parts welding process equipment to complete the positioning and welding of the skeleton parts. Although this method can ensure the processing accuracy and consistency of the product, the production cycle of the process equipment is long and the investment cost is high, which is not suitable for the principle of rapid entry of new products into the market in the early stage;

[0003] In order to quickly and accurately complete the production of the left and right side enclosures of the cab and ensure the stability of the quality of the same batch of products, a suitable welding device is needed. In the prior art, the skeleton is generally fixed on the base of the welding device, and the skeleton is welded by a welding head. The skeleton is fixed by a fixed structure on the base. However, the skeletons have different shapes. In order to adapt to the structure of agricultural machinery, some skeletons are asymmetrical and have special shapes.
