Unmanned aerial vehicle engine pipe body support welding positioning device

The invention provides an unmanned aerial vehicle engine pipe body support welding positioning device which comprises a first positioning support, a second positioning support and a third positioning support which are respectively used for accurately positioning a first pipe body, a second pipe body and a third pipe body of an engine pipe body support. The pin columns with the holes penetrate into the pipe bodies to form assembling base points of the engine, the bolts and the nuts penetrate into the pin column holes of the pipe bodies to position and fasten the pipe bodies, and the positioning accuracy of the assembling base points of the engine and the reliability of the positioning mode can be guaranteed. According to the correlation among the pipe bodies of the unmanned aerial vehicle support, the pipe bodies can be combined together through the engine support welding and positioning device, and accurate positioning of the support is achieved. Through accurate positioning of the engine support, the engine
