Abstract

The present invention discloses a portable hand-held electron gun for space on-orbit operation, belonging to the technical field of space environment material processing. The handheld electron gun mainly comprises an external focusing coil, an electron gun shell, an operating handle and an electron gun core contained inside the electron gun shell. One end of the electron gun housing is fixedly connected with the anode mounting flange, and the other end is fixedly connected with the operating handle. The insulator control is fixedly connected with the inner surface of the electron gun housing to connect one end of the operating handle. One end surface of the cathode holder is fixedly connected with the cathode, and the other end is connected with the anode and the cathode of a connecting electrode. The binding electrode is fixedly connected with the cathode holder and is connected with the anode or the cathode of the connecting electrode, and the cathode and the binding electrode form an equipotential. The anode and the focusing coil are respectively fixed on both sides of the anode mounting flange and the anode is connected with the equipment's earth line. The anodes and the cathodes of a cathode high voltage power supply connector, the focus coil joint and the equipment's earth line are respectively connected with the anode and the cathode of the connecting electrode.

Description

technical field [0001] The invention relates to a hand-held electron gun, which belongs to the technical field of space environment material processing. Background technique [0002] With the development of my country's space activities such as deep space exploration, space stations, and space-based launch platforms, new requirements have been put forward for services such as on-orbit construction, maintenance, assembly and utilization of spacecraft. Foreign studies have proved that electron beam technology is the most suitable and efficient processing method in the vacuum environment of space, and can be used for cutting, welding, spraying, additive manufacturing and other operations. [0003] The principle of space electron beam welding equipment is the same as that of ground equipment, but there are huge differences in structure. Because space is a natural high-vacuum environment, the electron gun used in space can be made into an open structure without considering the h...
