[0023] This embodiment provides a welding positioning device for an unmanned aerial vehicle engine pipe support, and its structure is as Figures 1 to 3 shown, including a first positioning bracket 1, a second positioning bracket 2 and a third positioning bracket 3, which are respectively used to accurately position the first pipe 4, the second pipe 5 and the third pipe 6 of the engine pipe support. Among them, the first positioning bracket 1 is located at the front of the entire positioning device and is used to position the first pipe 4 of the engine support. The second positioning bracket 2 is located at the upper rear side of the first positioning bracket 1 and is used to position the second pipe 5 of the engine support. The third positioning bracket 3 is located at the lower rear side of the first positioning bracket 1, and the second positioning bracket 2 is above it, and is used to position the third pipe 6 of the engine support. The entire positioning device positions and fastens the first pipe 4, the second pipe 5 and the third pipe 6, so that the mutual positioning accuracy requirements are formed between the pipes, meeting the accuracy control and dimensional requirements of the engine support, and ensuring the reliable assembly of the engine.

[0024] As Figure 4As shown in the figure, the first positioning bracket 1 mainly includes a first cross beam 1-1, a first longitudinal beam 1-2 and a reinforcing rib 1-3. Among them, the two first longitudinal beams 1-2 are fixedly connected to both ends of the first cross beam 1-1. The rear end of the first longitudinal beam 1-2 is fixedly connected to the support rod 3-2 of the third positioning bracket 3. The reinforcing rib 1-3 is connected between the first longitudinal beam 1-2 and the support rod 3-2. A positioning attachment seat is installed at the front end of each first longitudinal beam 1-2, and a bolt 7 and a nut 8 are arranged on each positioning attachment seat. When positioning, the bolt 7 passes through the positioning attachment seat and penetrates the pin hole of the first pipe body 4, and after connecting the first longitudinal beam 1-2 with the first pipe body 4, it is tightened and fixed by the nut 8.

[0025] As Figure 5 shown in the figure, the second positioning bracket 2 mainly includes a second cross beam 2-1. Among them, the second cross beam 2-1 is fixedly connected to the tops of the two support rods 3-2 of the third positioning bracket 3. Positioning attachment seats are installed at both ends of the second cross beam 2-1, and a bolt 7 and a nut 8 are arranged on each positioning attachment seat. When positioning, the bolt 7 passes through the positioning attachment seat and penetrates the pin hole of the second pipe body 5, and after connecting the second cross beam 2-1 with the second pipe body 5, it is tightened and fixed by the nut 8.

[0026] As Figure 6 shown in the figure, the third positioning bracket 3 mainly includes a third cross beam 3-1 and a support rod 3-2.
