Description

Technical Field

[0001] The invention belongs to the technical field of waveguide feeders, and in particular relates to a flangeless waveguide component welding detection device suitable for flangeless waveguide components. Background Art

[0002] In high-frequency radar systems, waveguide components are widely used to reduce insertion loss and increase gain. In practical applications, in order to reduce the increase in volume and weight caused by flanges, flangeless waveguide connections have gradually been adopted. At present, flangeless waveguide components used in engineering mostly use welding to achieve the connection between waveguide components, which mainly include sleeve welding or direct butt welding. Whether the final product can meet the performance index requirements depends entirely on whether the welding process is qualified. In the prior art, waveguide components are mostly welded one section at a time to finally form a complete waveguide component.

[0003] However, the welding of waveguide components has high technical requirements for welders and is easily affected by human factors. The sequential welding method will cause extremely small deformation at a single end. The small deformation at each step will lead to a large deviation in the size of the entire waveguide component after the welding is completed at the final end, which will eventually affect the electrical performance indicators of the system. Therefore, special tooling is required for fixing. However, the spatial structure of satellite-borne products is complex, and the size of each waveguide component is different. More than 200 sets of waveguide component tooling are required for a satellite, resulting in high tooling costs. In addition, the waveguide components are currently arranged in an irregular space when in use, which brings great detection difficulties to quality inspectors. Summary of the invention
