In actual use, on the assembly platform 7, the plurality of vertically adjustable supports can be used to position and level the top plate 6-1, so as to facilitate the spot welding of the straight side plates 6-3 on both sides of the top plate 6-1. After the spot welding of the top plate 6-1 and the straight side plates 6-3 is completed, a plurality of horizontally adjustable supports are installed between the two straight side plates 6-3. The plurality of horizontally adjustable supports can be used to limit the horizontal spacing between the two straight side plates 6-3. When welding the top plate 6-1 and the straight side plates 6-3, the bottom ends of the two straight side plates 6-3 can be prevented from being deformed close to each other, which helps to improve the welding quality of box-type thin-walled cavity welded parts.

[0025] like Figure 3 and Figure 4 As shown, in this embodiment, the vertically adjustable support and the horizontally adjustable support both include a steel pipe 1, a first end cover 2 and a second end cover 3, and a fixed support 4 is threadedly connected to the first end cover 2, and an adjustment support is threadedly connected to the second end cover 3. During actual use, the fixed support 4 is fixed and stationary, and the length of the vertically adjustable support or the horizontally adjustable support can be adjusted by manually screwing the adjustment support, which facilitates disassembly and assembly.

[0026] In this embodiment, the adjustment support includes a screw 5-1, a support column 5-2 and an operating rod 5-3. In actual use, the operator holds the operating rod 5-3, rotates the support column 5-2 and the screw 5-1, and can adjust the extension length of the screw 5-1 screwed into the second end cover 3, thereby achieving the purpose of adjusting the length of the vertical adjustable support or the horizontal adjustable support.

Then, a top panel 6-1 is placed on the top of the plurality of vertically adjustable supports. By adjusting the heights of the plurality of vertically adjustable supports, the top panel 6-1 can be leveled. Then, spot welding is performed between the top panel 6-1 and the U-shaped side panel 6-2. Secondly, two straight side panels 6-3 are respectively assembled on both sides of the top panel 6-1, and a plurality of vertically adjustable supports are arranged between the top panel 6-1 and the straight side panel 6-3 and the U-shaped side panel 6-2. Spot welding is performed between the profiled side panels 6-2 and the straight side panels 6-3; then, a plurality of horizontally adjustable supports are arranged between the two straight side panels 6-3, and the horizontal spacing between the two straight side panels 6-3 is precisely positioned by adjusting the lengths of the plurality of horizontally adjustable supports. After that, the box-type thin-walled cavity welded parts can be welded. During the welding process, the bottom ends of the two straight side panels 6-3 of the box-type thin-walled cavity welded parts will not be deformed by approaching each other, and this helps to improve the quality of weld formation, facilitating promotion and application.
