Abstract

The invention relates to the technical field of welding auxiliary devices, in particular to a fast welding assembly device for aerospace junction boxes, including a base, a welding platform is fixedly installed on the top of the base, the welding platform is made of carbon steel, and a welding platform is placed on the top of the welding platform. The junction box, the welding platform is fixedly equipped with clamp base, elbow clamp and material block, the clamp base is fixedly installed with the pressure clamp that touches the front side wall of the junction box, and the base is located on the rear side of the welding platform, and the left and right ends are fixedly installed with XYZ Three-axis slide table, the top of the XYZ three-axis slide table is fixedly installed with a support seat, the support seat is fixedly connected with a screw seat, the screw seat is threaded with a lead screw, and the lead screw is detachably installed with a threading pipe and a screw seat. The inclination is complementary to the angle to be welded of the threading pipe. In the present invention, the welding platform is made of carbon steel, which can realize rapid heat dissipation of the junction box, well solve the problem of local deformation of the junction box during the welding process, and improve the quality of the finished product of junction box welding.

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...

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
