[0035] Embodiment 1

[0036] This embodiment provides a side panel assembly welding device, which is used to weld a V-shaped bracket to both sides of the side panel to form a side panel assembly. Figure 1 As shown, the bottom of the V-shaped bracket and the front and rear ends of the side surround are provided with mounting holes, namely a1, a2, and a3.

[0037] As attached Figure 2 As shown, the welding device comprises a base 1, a first clamp 2 and a second clamp 3 for fixing the V-shaped bracket and the side panel, respectively. Figure 3 As shown, the base 1 includes a base frame 1.1, a swivel seat 1.2, a support roller 1.3 and a fixing pin 1.4. The swivel seat 1.2 is rotatably mounted on the base frame 1.1. A plurality of support rollers 1.3 are arranged between the swivel seat 1.2 and the base frame 1.1. The plurality of support rollers 1.3 are evenly distributed on the bottom surface of the swivel seat 1.2 with the rotating shaft of the swivel seat as the center. A fixing pin 1.4 is arranged on the base frame 1. The swivel seat 1.2 is provided with two 180° positioning pin holes (not shown in the figure). The base designed in this embodiment can loosen the fixing pin to operate the swivel seat to rotate, so as to facilitate the adjustment of the welding position of the welded parts to be arranged on the swivel seat. In specific implementation, after the welding of one side of the side enclosure is completed, the fixing pin is loosened, the swivel seat is controlled to rotate 180°, and the fixing pin is inserted into the positioning pin hole to lock the position of the swivel seat. At this time, the welding of the other side of the side enclosure can be completed.

[0038] Preferably, the base frame 1 is further provided with a circular track 1.5, and the support roller 1.4 is arranged on the circular track 1.5. This design can prevent the support roller from causing wear to the base frame.

[0039] Preferably, the bottom of the base frame 1.1 is also provided with two directional wheels and two steering wheels to facilitate the transfer of the welding device.

[0040] As attached Figure 4 and attached Figure 5As shown, the first clamp 2 includes a first fixing frame 2.1, a positioning pin 2.2, a side limit block 2.3, a Z-shaped bracket 2.4 and a clamping assembly 2.5. The first fixing frame 2.1 is arranged on the swivel seat 1.2. One end of the Z-shaped bracket 2.4 is fixedly mounted on the top of the first fixing frame 2.1. The two side limit blocks 2.3 are arranged on both sides of the top of one end of the Z-shaped bracket 2.4 connected to the first fixing frame 2.1, and are used to position the two sides of the V-shaped bracket. The positioning pin 2.2 is arranged on the first fixing frame 2.1 and is located in the middle of the limit blocks 2.3 on both sides, and is used to position the mounting holes on the V-shaped bracket. The clamping assembly 2.5 is arranged on the Z-shaped bracket 2.4 and is used to clamp the V-shaped bracket.
