Description

Technical Field

[0001] This utility model belongs to the field of high-precision X-ray tube technology, specifically relating to a high-precision X-ray tube electrode mounting device. Background Technology

[0002] High-precision X-ray tubes are mainly used in industrial inspection, materials analysis, and biological research. Their core function is to generate X-rays by bombarding a metal target with high-speed electrons, enabling high-precision imaging and structural analysis. Their structure primarily consists of a vacuum tube and two electrodes: a cathode and an anode. Vacuum tubes come in two types: closed-tube and open-tube. In a closed-tube tube, both the cathode and anode are enclosed within the vacuum tube, eliminating the need for external evacuation. Open-tube tubes are often modular, allowing for replacement of either the cathode or anode / target. They include valves and can be connected to an external vacuum pump for evacuation, offering a wider high-pressure range and higher precision. However, the current open-tube vacuum tubes are cumbersome and inconvenient to install and remove the cathode and anode, lacking flexibility and ease of use, which urgently needs to be addressed. Utility Model Content

[0003] In view of this, the purpose of this utility model is to provide a high-precision X-ray tube electrode mounting device, which enables convenient disassembly and assembly of the corresponding electrodes, thereby solving the above-mentioned problems.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a high-precision X-ray tube electrode mounting device, comprising a vacuum tube, a cathode, and an anode. The vacuum tube consists of a tube body and two end caps. Both ends of the tube body are open, and each end face has several blind holes arranged in a circular pattern. A support is fixedly mounted on the outer side of the tube body corresponding to each blind hole. A horizontally rotating shaft is mounted on the support. A transmission box is fixedly connected to the end of the shaft away from the tube body. There is a gap between the side of the transmission box near the tube body and the outer side of the tube body. A lead screw is horizontally rotating inside the transmission box. The end of the lead screw away from the shaft extends out of the transmission box and is fixedly connected to a handle. The lead screw is threaded with a slider. A guide groove is provided on the side of the transmission box away from the tube body corresponding to the slider. The slider extends out of the transmission box through the corresponding guide groove and is fixedly connected to a limiting plate. An insertion shaft is fixed on the side of the limiting plate near the tube body. The cathode and anode are respectively fixed through and fixed on the end caps. Several through holes are provided on the edge of the end caps. The end caps abut against the left and right ends of the tube body respectively. After the transmission box is rotated 180 degrees, the insertion shaft can correspond to the corresponding through hole and blind hole. The limiting plate abuts against the outside of the end cap, and the insertion shaft passes through the corresponding through hole and is inserted into the corresponding blind hole.

[0005] Preferably, the diameter of the end cap is adapted to the outer diameter of the corresponding end of the tube.

[0006] Preferably, a sealing gasket is provided on the side of the end cap near the tube body.

[0007] Preferably, the insert shaft is adapted to the corresponding through hole and blind hole.

[0008] Preferably, the slider is adapted to the corresponding guide groove.

[0009] Preferably, the tube body is provided with a vacuum port equipped with a vacuum check valve.

[0010] The beneficial effects of this invention are as follows: In the initial state, the limiting plate and the insertion shaft are located on the side away from the tube body, thus not affecting the installation of the electrodes. When installing the cathode and anode electrodes, the corresponding electrodes can be inserted into the tube body first until the corresponding end cap abuts against the corresponding end of the tube body, and the through hole is aligned with the corresponding blind hole. Then, by rotating the transmission box 180 degrees through the rotating shaft, the limiting plate and the insertion shaft can be rotated to the side closer to the tube body, at which point the insertion shaft can be aligned with the corresponding through hole and blind hole. Next, while keeping the transmission box stationary, the rotating handle is rotated, driving the lead screw to rotate. Through the threaded connection between the slider and the lead screw, and the guiding action of the guide groove on the slider, the limiting plate and the insertion shaft move towards the end cap until the limiting plate abuts against the end cap, so that the insertion shaft passes through the corresponding through hole and is inserted into the corresponding blind hole. This presses the end cap tightly and locks it onto the corresponding end of the tube body, thus completing the installation of the corresponding electrodes. To remove the corresponding electrode, simply reverse the corresponding handle to move the limiting plate away from the tube body until the insertion shaft exits the corresponding through hole. This releases the clamping and locking of the end cap and the locking of the transmission box. Then, rotate the transmission box to move the limiting plate away from the tube body, allowing the end cap with the corresponding electrode to be removed, completing the removal of the electrode. This simple and convenient operation enables flexible and easy replacement of the corresponding electrode, making it more practical. Attached Figure Description

Detailed Implementation

[0013] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments: like Figures 1 to 8 As shown, a high-precision X-ray tube electrode mounting device includes a vacuum tube 1, a cathode 2, and an anode 3. The vacuum tube 1 consists of a tube body 4 and two end caps 5. Both ends of the tube body 4 are open, and several blind holes 6 are provided on the corresponding end faces in a circularly spaced manner. A support seat 7 is fixed on the outer side of the tube body 4 corresponding to each blind hole 6. A rotating shaft 8 is horizontally and rotatably mounted on the support seat 7. A transmission box 9 is fixedly connected to the end of the rotating shaft 8 away from the tube body 4. There is a gap between the side of the transmission box 9 near the tube body 4 and the outer side of the tube body 4. A lead screw 10 is horizontally and rotatably mounted inside the transmission box 9. The end of the lead screw 10 away from the rotating shaft 8 extends out of the transmission box 9 and is fixedly connected to a handle 11. A slider 12 is threaded onto the lead screw 10. A guide groove 13 is provided on the side of the transmission box 9 away from the tube body 4 corresponding to the slider 12. The slider 12 extends out of the transmission box 9 through the corresponding guide groove 13 and is fixedly connected to a limiting plate 14. An insert shaft 15 is fixedly mounted on the side of the limiting plate 14 near the tube body 4. The cathode 2 and anode 3 are respectively fixed to the two end caps 5. Several through holes 16 are opened on the edge of the end caps 5. The two end caps 5 are respectively abutted against the left and right ends of the tube body 4. After the transmission box 9 is rotated 180 degrees, the insertion shaft 15 can correspond to the corresponding through hole 16 and blind hole 6. The limiting plate 14 abuts against the outside of the end cap 5, and the insertion shaft 15 passes through the corresponding through hole 16 and is inserted into the corresponding blind hole 6. In the initial state, the limiting plate 14 and the insertion shaft 15 are located on the side away from the tube body 4, thus not affecting the installation of the electrodes. When installing the cathode 2 and anode 3 electrodes, the corresponding electrodes can be inserted into the tube body 4 first until the corresponding end cap 5 abuts against the corresponding end of the tube body 4, and the through hole 16 is aligned with the corresponding blind hole 6. Then, by rotating the transmission box 9 180 degrees through the rotating shaft 8, the limiting plate 14 and the insertion shaft 15 can be rotated to the side closer to the tube body 4, at which point the insertion shaft 15 can be aligned with the corresponding through hole 16 and blind hole 6. Next, while keeping the transmission box 9 stationary, rotate the handle 11 to rotate the lead screw 10. Through the threaded connection between the slider 12 and the lead screw 10, and the guiding action of the guide groove 13 on the slider 12, the limiting plate 14 and the insertion shaft 15 move towards the end cover 5 until the limiting plate 14 presses against the end cover 5, causing the insertion shaft 15 to pass through the corresponding through hole 16 and be inserted into the corresponding blind hole 6. This presses the end cover 5 tightly and locks it onto the corresponding end of the tube body 4, thus completing the installation of the corresponding electrode. To remove the corresponding electrode, simply reverse the corresponding handle 11 to move the limiting plate 14 away from the tube body 4 until the insertion shaft 15 exits the corresponding through hole 16. This releases the pressing and locking of the end cover 5 and also releases the lock on the transmission box 9. Then, rotate the transmission box 9 to turn the limiting plate 14 away from the tube body 4, allowing the end cover 5 with the corresponding electrode to be removed, completing the removal of the corresponding electrode. Therefore, the operation is simple and convenient, and the corresponding electrodes can be flexibly and easily disassembled and replaced, making it more practical.

[0014] In this embodiment, the diameter of the end cap 5 is matched with the outer diameter of the corresponding end of the tube body 4 to ensure that the end cap 5 can be smoothly installed and sealed to the tube body 4.

[0015] In this embodiment, a sealing gasket 17 is provided on the side of the end cap 5 near the tube body 4 to ensure the sealing of the contact point.

[0016] In this embodiment, the insert shaft 15 is adapted to the corresponding through hole 16 and blind hole 6 to ensure that the insert shaft 15 is smoothly inserted into place.

[0017] In this embodiment, the slider 12 is adapted to the corresponding guide groove 13 to ensure the smooth movement of the slider 12.

[0018] In this embodiment, the tube body 4 is provided with a vacuum port 19 equipped with a vacuum check valve 18 for vacuuming the vacuum tube 1.

[0019] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
