Description

Technical Field

[0001] This utility model relates to the field of electron tube processing technology, specifically to an electron tube sealing tool. Background Technology

[0002] Sealing is a crucial step in completing the vacuum exhaust of an electron tube. It involves deforming a metal exhaust pipe to achieve a seal, maintaining the high vacuum environment achieved by the electron tube. The reliability of the metal seal directly affects the vacuum level of the electron tube, and thus its lifespan. For smaller electron tubes, the operator can manually support the tube and use specialized tools to clamp it. However, for larger electron tubes, the operator cannot stably support the tube, making clamping with specialized tools inconvenient and potentially causing injury. Furthermore, the position and magnitude of the longitudinal tension supporting the tube cannot be controlled, meaning the consistency of the sealing process cannot be controlled. Consequently, the reliability of the clamping seal is difficult to guarantee, impacting the electron tube's lifespan. Utility Model Content

[0003] To address the shortcomings of the existing technology, this utility model provides a vacuum tube sealing and unsealing fixture that can adapt to the sealing and unsealing operations of vacuum tubes of different sizes and masses, especially meeting the sealing and unsealing requirements of ultra-high power vacuum tubes with larger size and mass, and ensuring sealing and unsealing reliability.

[0004] To achieve the above-mentioned technical objectives, the technical solution adopted by this utility model is as follows:

[0005] An electron tube sealing fixture includes a force-applying device and a spring hook. Both ends of the spring hook are provided with hooks. One end of the spring hook is hung on the force-applying device, and the other end is used to connect to the end of the electron tube body away from the exhaust pipe.

[0006] As a preferred technical solution, the spring hook is a force-indicating spring.

[0007] As a preferred technical solution, the force-indicating spring is equipped with a dial and a pointer, and the dial is marked with scale markings.

[0008] As a preferred technical solution, the force spring is referred to as an electronic display spring scale, which is equipped with a force sensor and is communicatively connected to the electronic display screen.

[0009] As a preferred technical solution, the force-applying device is a lifting hoist.

[0010] The beneficial effects of this utility model are:

[0011] This utility model relates to a vacuum tube sealing and unsealing fixture, which is applied to the sealing and unsealing process of large-volume and large-mass vacuum tubes. It uses a force-applying device to provide lifting force instead of manual support for the vacuum tube, so that the sealed exhaust pipe is separated from the vacuum acquisition system, improving the convenience and safety of operation and meeting the sealing and unsealing requirements of ultra-high power vacuum tubes.

[0012] The electron tube sealing and unsealing fixture of this invention monitors the magnitude of external tension in real time during the sealing and unsealing process using a force-indicating spring scale, ensuring consistency in the sealing process and reliability of electron tube sealing and unsealing.

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely represents selected embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0019] A vacuum tube sealing fixture, such as Figures 1-3As shown, it includes a force-applying device 1 and a spring hook 2. Both ends of the spring hook 2 are provided with hooks. One end of the spring hook 2 is hung on the force-applying device 1, and the other end is used to connect to the end of the electron tube body 3 away from the exhaust pipe 4.

[0020] When the electron tube is vented, the electron tube body 3 is hung on the force application device 1 by the spring hook 2. The electron tube body 3 is sealed with the vacuum acquisition system 6 by the vent pipe 4 and the flange 5 to maintain a high vacuum state. After the electron tube is vented by the vacuum acquisition system 6, the force application device 1 is turned on to apply an upward external pulling force to the electron tube body 3. At the same time, a special tool is used to deform the material of the vent pipe 4 to achieve sealing and cutting (i.e., separation). The force application device 1 causes the sealed vent pipe blade to move upward longitudinally and separate from the vacuum acquisition system 6.

[0021] Preferably, the spring hook 2 is a force-indicating spring scale. In one specific embodiment, the force-indicating spring scale is equipped with a dial 21 and a pointer 22. The dial 21 is marked with scale markings, which are determined according to the spring constant and the spring elongation. When the spring is stretched, the pointer 22 will point to the corresponding scale marking, thereby reading the magnitude of the force. In one specific embodiment, the force-indicating spring scale is called an electronic display spring scale. The electronic display spring scale is equipped with a force sensor, which is communicatively connected to an electronic display screen 23. The force sensor is used to measure the magnitude of the force and displays the result on the electronic display screen 23.

[0022] Preferably, the force-applying device 1 is a lifting hoist, which is fixed at the top of the operating position and provides lifting force to the electron tube.

[0023] This utility model discloses a vacuum tube sealing and unsealing fixture, applicable to the sealing process of large-volume and heavy vacuum tubes. It replaces manual support of the vacuum tube with a lifting force provided by a force-applying device, separating the sealed exhaust pipe from the vacuum acquisition system, improving operational convenience and safety, and meeting the sealing requirements of ultra-high-power vacuum tubes. During the sealing process, a force-indicating spring scale monitors the external tension in real time to ensure consistency in the sealing process and guarantee the reliability of the vacuum tube sealing.

[0024] Of course, there may be other embodiments of this utility model. Without departing from the spirit and essence of this utility model, those skilled in the art can make various corresponding changes and modifications based on this utility model, but these corresponding changes and modifications should all fall within the protection scope of the appended claims of this utility model.
