Description

Technical Field

[0001] The invention relates to the technical field of X-ray tube cores, and in particular to a tooling used for dynamic balance testing of X-ray tube cores. Background Art

[0002] The X-ray tube core is the main core component of the CT machine. The X-ray tube core is a vacuum diode working under high voltage. Generally, the X-ray tube core is connected to the cathode component and the anode component through a metal shell, and the anode component includes an anode target plate, a rotor and a bearing.

[0003] For the assembly of all X-ray tube cores, the assembly of the anode and the dynamic balancing of the anode are key steps, which are to ensure the anode rotation stability and noise of the X-ray tube core, and further improve the working stability of the X-ray tube. In other words, in order to ensure the stability of the X-ray tube core, a dynamic balancing test is required. However, in the traditional method, the dynamic balancing test of the X-ray tube core is performed in the air state, and the driving test of the bearing of the anode component in the air state will cause oxidation and damage of the bearing, which can easily reduce the life of the X-ray tube core.
