Problems solved by technology

Usually, when the junction box is assembled and welded, it is difficult to guarantee or even locate the angle and position of each component, and because the junction box used in aerospace is made of titanium alloy, and the thermal conductivity of titanium alloy is relatively low. Low (the thermal conductivity of titanium is 15.24W / (m K), and the thermal conductivity of various titanium alloys is about 50% lower than that of titanium), which makes it easier for local welding deformation to occur during welding of titanium alloys, and even more special When the parts are being welded, welding assistants are required to manually hold them together for assembly
It is difficult to ensure the relative position accuracy of related parts by manual alignment, and it is easy to cause burn hazard to welding assistants during welding
[0003] To sum up, when the titanium alloy junction box for aerospace is assembled and welded, it is difficult to guarantee the relative position of each part, and the titanium alloy is prone to deformation during welding, which leads to the traditional welding method is easy to cause a large number of junction box welding. unqualified products

Abstract

The invention relates to the technical field of welding auxiliary devices, in particular to a junction box welding rapid assembly device for aerospace. The device comprises a base, a welding platform is fixedly installed at the top end of the base and made of carbon steel, a junction box is placed at the top end of the welding platform, and a clamp seat, an elbow clamp and a material leaning block are fixedly installed on the welding platform. The clamp seat is fixedly provided with pressing tongs abutting against the front side wall of the junction box, the left end and the right end, located on the rear side of the welding platform, of the base are each fixedly provided with an X-Y-Z-axis sliding table, the top ends of the X-Y-Z-axis sliding tables are each fixedly provided with a supporting seat, the supporting seats are fixedly connected with lead screw seats, the lead screw seats are in threaded connection with lead screws, the lead screws are detachably provided with threading pipes, and the inclination degrees of the lead screw seats are complementary with the to-be-welded angles of the threading pipes. The welding platform is made of the carbon steel, rapid heat dissipation of the junction box can be achieved, the problem of local deformation of the junction box in the welding process is well solved, and the finished product quality of junction box welding is improved.

Description

technical field [0001] The invention relates to the technical field of welding auxiliary devices, in particular to a fast welding assembly device for aerospace junction boxes. Background technique [0002] During the welding process of the junction box, the welding personnel need to adjust the relative positions of the parts of the junction box to ensure the requirements of the angle and position of each part. Usually, when the junction box is assembled and welded, it is difficult to guarantee or even locate the angle and position of each component, and because the junction box used in aerospace is made of titanium alloy, and the thermal conductivity of titanium alloy is relatively low. Low (the thermal conductivity of titanium is 15.24W / (m K), and the thermal conductivity of various titanium alloys is about 50% lower than that of titanium), which makes it easier for local welding deformation to occur during welding of titanium alloys, and even more special When the parts a...
