A welding filler metal is arranged at the butt joint gap of the box-shaped cabin section body 7. By using the vacuum brazing method to perform segmented welding and assembly on the ultra-thin wall box-shaped cabin section model, the problem that the ultra-thin wall box-shaped cabin section model is burned through can be effectively avoided, the weld formation can be ensured, and the welding filler metal can be wrapped at the weld positions of the two box-shaped cabin section bodies 7 to achieve the effect of completing welding at one time. The positioning component 6 includes an annular installation frame 601 installed on the inner wall of the installation frame 4. Equally spaced annularly distributed inlets and outlets 608 are formed in the inner wall of the annular installation frame 601. Rack plates 603 are movably arranged on the inner walls of the inlets and outlets 608. A driving mechanism is arranged between the rack plates 603. Clamping seats 604 are installed at one ends of the rack plates 603 respectively. The driving mechanism includes tooth columns 609 rotatably arranged at equal intervals in the annular installation frame 601, and the tooth columns 609 are respectively meshed with the rack plates 603. A bearing sleeve 606 is installed on the inner wall of the annular installation frame 601, and a gear ring 607 is installed on the inner wall of the bearing sleeve 606. The gear ring 607 is meshed with the tooth columns 609. An installation seat 610 is fixed on the outer wall of the annular installation frame 601, and an installation hole communicating with the inside of the annular installation frame 601 is formed at one end of the installation seat 610. A driving screw 612 is rotatably arranged on the inner wall of the installation hole through a bearing. A knob 602 is fixed at one end of the driving screw 612. A threaded hole 611 is formed at one end of one of the rack plates 603, and the inner wall of the threaded hole 611 is screwed with the outer wall of the driving screw 612. Equally spaced connecting grooves 613 are arranged on one side of each clamping seat 604, and rollers 605 are rotatably connected to the inner walls of the connecting grooves 613. The box-shaped cabin section body 7 is arranged between the rollers 605. By driving the driving screw 612 to rotate through the knob 602, and cooperating with the screwing action of the driving screw 612 and the threaded hole 611 to drive the rack plate 603 to move in the inlet and outlet 608, the tooth column 609 can be driven to rotate under the meshing action of the rack plate 603 and the gear ring 607 and the meshing action of the rack plate 603 and the tooth column 609, and the rack plate 603 and the clamping seat 604 are driven to move, so as to clamp and position the two box-shaped cabin section bodies 7 and ensure the butt joint accuracy of the weld positions.

[0025] Specifically, a support table 12 is installed between the bottoms of the two annular installation frames 601, and a collection box 5 is slidably arranged on the support table 12.

[0027] The working principle of the present utility model is as follows: During use, the user places two box-shaped cabin section bodies 7 inside two positioning assemblies 6. By driving the driving screw 612 to rotate through the knob 602, and with the screwing action between the driving screw 612 and the threaded hole 611, the rack plate 603 is driven to move inside the inlet and outlet 608. Thus, under the meshing action between the rack plate 603 and the gear ring 607 and between the rack plate 603 and the tooth post 609, all the tooth posts 609 are driven to rotate, driving all the rack plates 603 and the clamping seats 604 to move, thereby being able to clamp and position the two box-shaped cabin section bodies 7 and ensuring the docking accuracy of the weld positions. Then, the weld positions of the two box-shaped cabin section bodies 7 are spot-fixed by means of argon arc cold welding and hand-held laser welding to form a preliminary welding and fixing operation. Then, the welding filler metal is wrapped around the weld positions of the two box-shaped cabin section bodies 7. The forward and reverse motor 2 in the feeding and discharging mechanism drives the threaded rod 3 to rotate. Through the screwing action between the threaded rod 3 and the movable sleeve 8, the mounting frame 4, the positioning assembly 6, and the box-shaped cabin section body 7 are driven into the vacuum brazing furnace 1. The furnace door of the vacuum brazing furnace 1 is closed, and thus the ultra-thin wall box-shaped cabin section model is segmentally welded and assembled by means of vacuum brazing to achieve the operation of completing the welding at one time. After the welding is completed, the furnace door is opened, and the mounting frame 4 can be driven to reset under the action of the feeding and discharging mechanism, realizing the performance of automatic feeding and discharging.

[0028] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above exemplary embodiments, and without departing from the spirit or basic characteristics of the present utility model, the present utility model can be implemented in other specific forms.
