The invention discloses an X-ray tube cathode and anode clamping and spacing adjusting mechanism. The mechanism comprises a bottom plate. The mechanism is characterized in that the top surface of the bottom plate is in threaded connection with a supporting guide column, the top end of the supporting guide column is in threaded connection with a top plate, a servo sliding table is fixedly mounted on the central axis of the top surface of the bottom plate, the top of the servo sliding table is in threaded connection with a movable guide column, and an anode fixing plate is fixedly installed on the left side of the top plate. According to the X-ray tube cathode and anode clamping and spacing adjusting mechanism, by means of the servo sliding table, a cathode clamping part sleeve can be driven by a servo motor to move left and right, so that the gap between the cathode and the anode of an X-ray tube can be adjusted, the whole process is easy to operate, the working principle is easy to implement, and the mechanism has high practical value; and the distance between an anode fixing plate and a sliding block can be adjusted, so that the mechanism can meet the correction of anodes and cathodes of X-ray tubes of different models, and the practicability of the mechanism is improved.
Description
technical field [0001] The invention relates to the technical field of X-ray tubes, in particular to an X-ray tube cathode and anode clamping and adjustable distance mechanism. Background technique [0002] X-ray tubes are vacuum diodes that operate at high voltages. Contains two electrodes: one is a filament for emitting electrons, which acts as a cathode, and the other is a target for receiving electron bombardment, which acts as an anode. X-ray tubes are used in medicine for diagnosis and treatment, and in industrial technology for non-destructive testing of materials, structural analysis, spectral analysis, and film exposure. [0003] In the current actual manufacturing and testing of X-ray tubes, due to the lack of a device that can quickly and conveniently adjust the distance between the cathode and the anode, it is very inconvenient to adjust the distance between the cathode and the anode during use. Contents of the invention [0004] The object of the present inv...
