Embodiment 1

[0032] The glue filling fixture of the traveling wave tube electron gun in the first embodiment includes a "Π" shaped container, and the glue filling fixture is set on one end of the electron gun through the opening side of the "Π" shaped container, and the glue filling fixture also includes a square The diversion container is provided with a φ10mm through hole on the side near the bottom of the electron gun. The bottom end of the "∏" shaped container is kept flat, and the height of the diversion container is higher than that of the "∏" shaped container. The φ 10mm through hole that the through hole of the container communicates; the through hole of the diversion container is a circular hole in the present embodiment, and when the diversion container is fixedly connected with the "Π" shape container, the center of circle of the through hole of the diversion container is in line with the The centers of the through-holes of the "∏"-shaped container are roughly coincident.

Abstract

The invention discloses a glue pouring clamp of a travelling wave tube electron gun. The glue pouring clamp is an n-shaped container and further comprises a diversion container, a through hole is arranged in the side surface, which is close to the bottom end of the electron gun, of the diversion container, when the diversion container and the n-shaped container are fixedly connected, the bottom end of the diversion container maintains level with the bottom end of the n-shaped container, the height of the diversion container is greater than that of the n-shaped container, and a through hole communicating with the through hole of the diversion container is arranged in the side surface, which is close to the bottom end of the electron gun and is in contact with the diversion container, of the n-shaped container. By using the glue pouring clamp and the glue pouring method, secondary bubble discharge processing is unnecessary, and thus the labor, time and energy cost is reduced; change of the magnetic field value of a magnet ring, result from change of the temperature of the rare earth magnet ring, caused by affected heat conduction of a travelling wave tube due to silicone rubber mingled in the gap between the travelling wave tube and a base plate, is prevented; and the situation where dynamic parameters of the travelling wave tube are changed in a silicon rubber removing process is avoided.

Description

technical field [0001] The invention relates to a jig for assembling an electron gun, in particular to a jig for pouring glue into a traveling wave tube electron gun. Background technique [0002] Traveling wave tube is a kind of microwave device, which is an important electronic device used in the fields of microwave relay communication, radar, electronic countermeasures and satellite communication, etc., and plays a role in signal amplification of electromagnetic interference. As a core component of the traveling wave tube, the electron gun needs to ensure that its poles are well insulated. [0003] Different traveling wave tubes have unique structures. In the high voltage part of the traveling wave tube electron gun, silicone rubber potting treatment is required. Stirring, however, during the stirring process, tiny fine bubbles will be produced. For this reason, the rubber needs to be defoamed once; when the traveling wave tube electron gun is filled with silicone rubber...
