Description

Technical Field

[0001] The present invention belongs to the technical field of waveguide feeders, and particularly relates to a waveguide feeder test welding device. Background Art

[0002] In high-frequency radar systems, waveguide components are widely used to reduce insertion loss and increase gain. In actual applications, in order to reduce the increase in volume and weight caused by flanges, flange-free waveguide connections have gradually begun to be adopted. Currently, most of the flange-free waveguide components applied in engineering use welding to connect waveguide feeders. Whether the final product can meet the performance index requirements depends on whether the welding process is qualified. Currently, most of the performance indexes of flange-free waveguides are detected by connecting electrical performance testing equipment after the waveguide feeders are processed.

[0003] However, the method of welding each section of the waveguide feeder in sequence will cause a large deviation in the size of the entire waveguide component after the welding of the final end due to extremely small deformation at a single end, ultimately affecting the electrical performance indexes of the system. Therefore, when detecting the electrical performance indexes of the waveguide feeder after welding, it often fails to meet the standards. And in the actual production process, usually the electrical performance test is qualified during the trial assembly of the components, but the deviation of the electrical performance indexes is large after welding, which greatly reduces the qualified rate of the products. Therefore, a special tooling is needed for fixing. However, the space structure of spaceborne products is complex, and the sizes of each waveguide feeder are different. More than 200 sets of waveguide feeder toolings are required for one satellite, resulting in a very high tooling cost.

[0004] To solve the above technical problems, someone designed a fixed monitoring device applicable to waveguide components of various sizes. This device can not only be used as a welding fixing tooling for various flange-free waveguides, but also as a fixture after the product is formed, solving the problem of welding size control of waveguide feeders. However, the above device cannot effectively solve the problem of the difference in the electrical performance of waveguide feeders before and after welding. Summary of the Invention
