[0013] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0014] like Figure 1 As shown, a micro-focus X-ray source oiling device comprises a fixed fixture 2, an X-ray source body 3, a molecular pump 7 and an oil barrel 4, wherein the X-ray source body 3 is fixed on the fixed fixture 2, and the X-ray source body 3 is connected with an oiling loop pipe 31 and an oil return loop pipe 32, one end of the oiling loop pipe 31 and the oil return loop pipe 32 are connected to the X-ray source body 3, and the other end is commonly connected to the oil barrel 4, and the oiling loop pipe 31 and the oil return loop pipe 32 are both installed with a solenoid valve 5; the X-ray source body 3 is also connected with a pneumatic loop pipe 6, one end of the pneumatic loop pipe 6 is connected to the X-ray source body 3, and the other end is fixedly connected with the molecular pump 7. The oil chamber of the oil barrel 4 contains insulating oil.

[0015] By adopting the above structure, the X-ray body is fixed in position by fixing the tooling 2, so that the X-ray source body 3 is fixed during oil filling to avoid oil leakage and facilitate oil filling; at the same time, the oil filling loop pipe 31 and the oil return loop pipe 32 are both provided with an electromagnetic valve 5 to control the oil filling loop pipe 31 and the oil return loop pipe 32, and the insulating oil in the oil barrel 4 flows into the X-ray source body 3 through the oil filling loop pipe 31, and then flows back from the X-ray source body 3 along the oil return loop pipe 32 to the oil barrel 4, which is conducive to automatic circulation oil filling and is more convenient and quick; by providing a molecular pump 7, a vacuum can be drawn during the circulation oil filling process to ensure that there is no air in the insulating oil, achieve a better insulation effect, avoid ignition, and utilize the vacuum system to prevent the generation of bubbles during the circulation oil filling process.

[0016] Specifically, if Figure 1 As shown, a vacuum pressure gauge 61 is also installed on the pneumatic circuit pipe 6.

[0017] By adopting the above structure, by installing the vacuum pressure gauge 61 on the pneumatic circuit pipe 6, it is helpful to read the vacuum degree accurately in real time and confirm whether the vacuum degree requirement during the oil injection process is met.

[0018] like Figure 1 As shown, the X-ray source body 3 is also provided with a sealing plate structure 33, and the oil injection circuit pipe 31, the oil return circuit pipe 32 and the start circuit pipe are all connected to the X-ray source body 3 through the sealing plate structure 33 on the X-ray source body 3. By providing the sealing plate structure 33, it is ensured that the connection between the X-ray source body 3 and the oil return circuit pipe 32 and the pneumatic circuit pipe 6 does not leak oil or air during oil injection, thereby improving the efficiency of oil injection.

[0019] like Figure 1 As shown, the oil delivery direction of the oil injection loop pipe 31 is opposite to that of the oil return loop pipe 32; and the oil in the oil barrel 4 flows along the oil injection loop pipe 31, passes through the X-ray source body 3, and then flows back from the oil return loop to the oil barrel 4. The insulating oil in the oil barrel 4 starts from the oil injection loop pipe 31, passes through the X-ray source body 3, and then flows back from the X-ray source body 3 to the oil barrel 4, and the oil injection is automatically circulated, saving costs.
