Abstract

The invention discloses an assembly mold and an assembly method for a composite tube shell spiral line slow-wave structure. The assembly mold comprises a grasp module, a support component and an installation component. The grasp module comprises a tube body and a clamp. The clamp comprises a grip-body and a support rod. An internal end face of the support rod is utilized for supporting and pressing on an external wall face of the spiral line and an external end face of the support rod is utilized for supporting and pressing on an internal wall face of the tube body. The support component comprises a support shaft lever and a support shaft chuck. The support shaft chuck is disposed between two adjacent support rods which make the spiral line have elastic deformation. The installation component comprises a first member bar and a second member bar. According to the deformability of the spiral, through the cooperation among assembly molds and spiral lines, the assembly of the composite tube shell spiral line slow-wave structure is achieved.

Description

technical field [0001] The invention belongs to the field of microwave vacuum electronic devices, and in particular relates to an assembly mold and an assembly method for a helical slow wave structure of a composite shell. Background technique [0002] At present, domestic broadband miniaturized traveling wave tubes generally adopt a traditional high-frequency structure, which consists of a shell with internal loading ribs, a helix, a ceramic rod, and peripheral pole pieces and backing rings. Due to the existence of the shell of this kind of high frequency structure, the utilization rate of magnetic flux is low, the volume of the magnetic focusing system increases, and due to the size limitation of the shell and the backing ring, the high frequency system will become a weak link of the whole tube of the traveling wave tube, which directly affects reliability of the manufacturing process. However, the miniaturized phase-coherent traveling wave tube imported from abroad adopt...
