X-ray tube with anode and cathode having rotation functions

Abstract

The invention discloses an X-ray tube with a cathode and an anode which have rotation functions. The X-ray tube comprises a cathode, an anode, a vacuum tube and a driving device, wherein the anode and the cathode are both arranged in the vacuum tube, the vacuum tube comprises a vacuum cover, a cathode fixing tube and an anode fixing tube, a driving device is arranged in each of the cathode fixing tube and the anode fixing tube and is connected with a coil, an anode handle of the anode is connected with the driving device by a rotation part, and a cathode root of the cathode is connected with the driving device. In the X-ray tube provided by the invention, the cathode and the anode both have the rotation functions, a target arranged in the anode is bombed through an electron beam generated by a tungsten filament of the cathode so as to high-efficiently generate X-ray, and the X-ray radiates outwards through an arbitrary protruding position; and moreover, the cathode and the anode simultaneously rotate, and the purpose of rotary radiation can be achieved. Therefore, the X-ray tube provided by the invention is simple in structure and high in working efficiency, is convenient to use, can operate in no need of labor consumption, and can be applied to various occasions of industrial X-ray machines.

Description

technical field [0001] The invention relates to the technical field of X-ray tubes, in particular to an X-ray tube in which the negative and positive poles have a rotating function. Background technique [0002] X-ray tubes are vacuum diodes that operate at high voltages. Contains two electrodes: one is a filament for emitting electrons, as a cathode, and the other is a target for receiving electron bombardment, as an anode, both stages are sealed in a high-vacuum glass or ceramic shell. With the advancement of science and technology, the manufacturing technology of X-ray tubes has become more and more mature. Installing X-ray tubes on X-ray machines is widely used in the field of non-destructive testing. [0003] At present, the structure of the existing X-ray tube is composed of three parts: the anode, the cathode and the glass shell that fix the two poles and maintain the high vacuum in the glass tube. The anode and the cathode are fixed in the glass shell, which is the ...
