Description

Technical Field

[0001] This utility model relates to the technical field of X-ray tube production equipment, and in particular to a rapid sealing device for the glass shell of an X-ray tube. Background Technology

[0002] The glass shell of an X-ray tube is not only a container for maintaining a high vacuum, but also a crucial insulator capable of withstanding tens of thousands or even millions of volts of high voltage, while also withstanding high temperatures and thermal shock. Its performance significantly impacts the stability and lifespan of the X-ray tube. To ensure a vacuum environment within the X-ray tube's glass shell, it needs to be rapidly sealed after evacuation. However, in actual production, quality control often necessitates reopening the seal for leak testing. After leak testing, to avoid resource waste, it needs to be resealed. However, the resealing process alters the sealing area, and existing sealing devices have fixed components that cannot be height-adjusted, making the resealing process relatively cumbersome. Therefore, this application proposes a rapid sealing device for X-ray tube glass shells. Utility Model Content

[0003] To address the above situation and overcome the shortcomings of existing technologies, this utility model provides a rapid sealing device for the glass shell of an X-ray tube. The technical solution it provides includes an operating table. The operating table is characterized by having a heat-resistant liner fixedly installed in its center, two symmetrically arranged hydrogen-oxygen spray guns embedded in the operating table about the heat-resistant liner, a lifting device at the upper end of the heat-resistant liner, a lifting rod driven by the lifting device, a support rod fixedly connected to the lifting rod, a support column fixedly connected to the support rod, a positioning cylinder coaxially arranged with the heat-resistant liner fixedly connected to the upper end of the support column, a sponge liner fixedly connected to the inner wall of the positioning cylinder, and a glass shell coaxially inserted and plugged into the positioning cylinder, abutting against the sponge liner. The lifting device includes two vertical rods fixedly connected to a heat-resistant liner. A top beam is fixedly connected to the upper end of the two vertical rods. The top beam and the heat-resistant liner are rotatably connected to a screw rod. The screw rod is located between the two vertical rods and is threadedly connected to the middle of the lifting rod. The two ends of the lifting rod are slidably connected to the two vertical rods respectively.

[0004] Preferably, the nozzles of both hydrogen-oxygen spray guns are arranged facing the axis of the positioning cylinder.

[0005] Preferably, a drive handwheel is coaxially fixedly connected to the upper end of the screw.

[0006] Preferably, the middle part of the lifting rod is integrally provided with a threaded sleeve that engages with the screw thread, and both ends of the lifting rod are integrally provided with sliding sleeves that are slidably connected to the vertical rods on their corresponding sides.

[0007] Preferably, the lower end of the operating table is fixedly connected to four legs arranged in a rectangular array.

[0008] The beneficial effects of this utility model are: In use, the positioning cylinder of this application can be used to position the embedded glass shell. The sponge lining inside the positioning cylinder has a certain elasticity, which facilitates the tight insertion of the glass shell into the positioning cylinder and keeps it stable, so as to seal the glass shell by the hydrogen-oxygen spray gun. Furthermore, the lifting device can move the positioning cylinder together with the glass shell, thereby facilitating the hydrogen-oxygen spray gun to seal the glass shell at the appropriate position. This solves the problem that it is inconvenient to operate the glass shell that needs to be resealed after quality inspection. This application has a simple structure, is easy to use, and has strong practicality. Attached Figure Description

[0015] The following is in conjunction with the appendix Figures 1-4 The specific embodiments of this utility model will be described in further detail.

[0016] In the first embodiment, the technical solution is as follows: When in use, the positioning cylinder 8 can be used to position the embedded glass shell 10. The sponge liner 9 inside the positioning cylinder 8 has a certain elasticity, which facilitates the tight insertion of the glass shell 10 into the positioning cylinder 8 and keeps it stable, so that the glass shell 10 can be melted and sealed by the hydrogen-oxygen spray gun 3. Furthermore, the lifting device 4 can drive the positioning cylinder 8 and the glass shell 10 to move together, thereby facilitating the hydrogen-oxygen spray gun 3 to melt and seal the glass shell 10 at a suitable position. This solves the problem that the glass shell 10, which needs to be resealed after quality inspection, is inconvenient to operate. The present application has a simple structure, is easy to use, and has strong practicality.

[0017] In Example 2, based on Example 1, specifically, when this application is used, the operating table 1 is fitted with a hydrogen-oxygen spray gun 3, which can release a hydrogen-oxygen flame at a temperature of up to 3,000 degrees Celsius, thereby instantly melting and sealing the glass shell 10. The two hydrogen-oxygen spray guns 3 are arranged opposite each other to ensure that the flame acts relatively evenly on the melting and sealing part of the glass shell 10, thereby rapidly melting and sealing the glass shell 10.

[0018] A lifting device 4 is installed on the heat-resistant liner. When the glass shell 10 needs to be resealed after being unsealed due to quality inspection, the resealing position changes, so it needs to be adjusted to a certain extent through the lifting device 4. During adjustment, the screw 12 on the top beam 11 is rotated clockwise. To facilitate the rotation of the screw 12, a drive handwheel 13 is provided. By rotating the screw 12 clockwise through the drive handwheel 13, the screw 12 will act on the lifting rod 5 through the screw sleeve 14. The lifting rod 5 is vertically slidably connected to the vertical rod 17 through the sliding sleeve 15. Therefore, the clockwise rotation of the screw 12 can drive the lifting rod 5 to slide upward along the vertical rod 17. The upward movement of the lifting rod 5 will drive the support rod 6 and the support column 7 to move upward together. Then, the positioning cylinder 8, which is fixedly connected to the support column 7, will also move upward synchronously. Consequently, the glass shell 10 inside the positioning cylinder 8 will move upward accordingly. Correspondingly, rotating the screw 12 counterclockwise will drive the lifting rod 5 and the positioning cylinder 8 and other related components to move downward.

[0019] In Example 3, based on Example 2, a support leg 16 is provided at the lower end of the operating table 1 to provide support for this application.
