The device comprises a base, a first component positioning tool, a second component positioning tool, a third component positioning tool, a fourth component positioning tool, a tail supporting rod positioning tool and a middle pipe fitting positioning tool; the base is of a frame type steel structure and is mainly formed by welding rectangular square pipes, six universal wheels are installed on the base, and the universal wheels are provided with brake devices, so that transferring is convenient; and each positioning tool is detachably fixed to the base, the positioning tools are used for positioning all parts of a light unmanned aerial vehicle fuselage framework, and overall welding of the fuselage framework is facilitated.

Description

technical field [0001] The invention belongs to the technical field of mechanical processing and welding, and in particular relates to a light-duty unmanned aerial vehicle fuselage frame welding device. Background technique [0002] The fuselage skeleton is the key structural load-bearing part of the AV500 unmanned helicopter. It is welded by pipe fittings and machined parts; it is mainly responsible for the installation of the engine and the main rotor system, which requires high-quality welds and rigid structures. Strong, product size welding deformation is small. Its dimensions are 2096×808×884, and its structure is as figure 1 shown. The material of the fuselage frame parts is 30CrMnSiA, mainly composed of thin-walled pipe fittings and thin-walled machined parts, which are welded by manual argon arc welding. The space structure of the fuselage frame is complex. The relative position and size tolerance between them is strict, and some welds are concentrated; the genera...
