Problems solved by technology

[0003] The problem to be solved by the present invention is to precisely control the height of the load assembly by using the height of the clamping rod and the depth of the longitudinal groove on the metal load in view of the strict requirements on the cooperation between the helix and the shell in the manufacturing process of the previous slow wave system. Thereby improving the manufacturing accuracy of the

Embodiment Construction

[0014] refer to figure 1 , showing the sectional view of the helical slow wave system. In the figure 1 is the metal load, the clamping rod 2 is inserted in the metal load longitudinal groove 1-1, the middle part is the helix 3, the outermost is the total metal tube shell 4, and in the total metal load There are protrusions 5 inside the tube shell.

[0015] refer to figure 2 , image 3 , represents the cross-sectional view of the metal load after orthopedic shaping, the longitudinal groove on the metal load in the figure is 1-1, the depth of the groove is a, and the height of the clamping rod fixed inside is b.

[0016] refer to Figure 4 , represents the assembly assembly of the helical slow wave system. The clamping rod 6 in the center of the figure is a tool core rod used to protect the helix and fix it to the fixture during the assembly process. It must be removed after assembly. The core rods 7 that three process assemblings are used also will be taken away after asse...

Abstract

The invention provides a method for manufacturing helix line slow-wave system of wide frequency band traveling wave tube which belongs to the microwave electronics device field. The system comprises the helix line coiling forming, the media clamp rod and a metal load assembly fixed in a metal load longitudinal groove. The system is assembled according with steps as follows: a. fixing the helix line, three metal load assembling pieces and three technique core rods for assembling into an assembly component on two ends by a locating clamp; b. inserting the assembly component into a small segment metal pipe case for assembling; c. moving the small segment metal pipe case, filling the assembly component into a total metal pipe case along a metal pipe case conducting channel, then removing the small segment metal pipe case. The method can increase manufacturing precision (tolerance 3-5 mum) of aperture between the helix line and the load component greatly, has little manufacturing labour amount, increases radiation ability of the whole slow-wave system, reduces crispness pressure of the clamp rod and reduces mortality of accessory.

Description

technical field [0001] The invention belongs to the field of microwave electronic devices, in particular to a manufacturing method of a helical slow wave system of a broadband traveling wave tube in microwave electronic devices. Background technique [0002] The structure and manufacturing technology of the helical slow wave system of broadband traveling wave tube should be able to meet different performance index requirements. Broadband traveling wave tubes require good dispersion characteristics, bandwidth and output parameters, which depend to a large extent on the structure and manufacturing process of the slow wave system. In order to realize the broadband dispersion characteristics and output parameters of the TWT, it is necessary to choose a reasonable structure and manufacturing process of the slow-wave system. Generally, in the manufacture of the slow wave system of the helical traveling wave tube, the manufacturing error of the helix and the shell, the stringent r...
