Description

Technical Field

[0001] This utility model relates to the field of X-ray tube technology, specifically to a device for disassembling the sealing ring of an X-ray tube. Background Technology

[0002] An X-ray tube is a vacuum diode that operates at high voltage. It contains two electrodes: a filament that emits electrons, serving as the cathode, and a target that receives the electron bombardment, serving as the anode. Both electrodes are sealed within a high-vacuum glass or ceramic housing.

[0003] X-ray tube electrode tubes are typically equipped with a sealing ring to maintain a high vacuum within the tube. This sealing ring is threaded to the inner wall of the electrode tube and has mounting holes for disassembly and installation. During X-ray tube maintenance or repair, a specific tool is inserted into the mounting hole, and then the sealing ring is removed or installed by rotating the tool.

[0004] However, because different models of X-ray tubes have different diameters of sealing rings, different tools are required for disassembly and installation, increasing the workload for users. Furthermore, engineers need to prepare multiple tool types to accommodate the sealing rings of different X-ray tube models. This is not only inconvenient for tool carrying, but also means that if the specialized tools for a particular X-ray tube model are lost, it may prevent the maintenance and repair of that model of X-ray tube. Therefore, we propose a device for disassembling the sealing rings of X-ray tubes. Utility Model Content

[0005] The technical problem this invention aims to solve is to overcome existing defects and provide a device for disassembling the sealing ring of an X-ray tube. This device adjusts the distance between the outer ends of the two sleeves according to the user's arm length and working condition. This design not only saves the user's effort but also improves user comfort. Activating the drive assembly causes the rotating shaft to rotate forward or backward. The rotating shaft drives the gear to rotate, which meshes with two racks. Because the rotating shaft rotates forward or backward, the two racks move in opposite directions or relative to each other. The racks drive the corresponding sleeves to move, thereby adjusting the distance between the two sleeves. Then, a first bolt is inserted into the first positioning hole and the first insertion hole, and threadedly connected to the second nut to fix the sleeves and ensure their stability. Then, the movable clamping plate and the fixed clamping plate of the disassembly assembly are clamped together. Next, the second bolt is passed through the corresponding second positioning hole and the second insertion hole. Then, the second bolt and the first nut are threaded together to fix the movable clamping plate. Finally, the user grips the sleeve and rotates it to remove the sealing ring of the X-ray tube. This design achieves the universality of disassembling and installing sealing rings of different diameters, which is convenient for engineers to carry and use, improves work efficiency, and can effectively solve the problems in the background technology.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a device for disassembling the sealing ring of an X-ray tube, comprising a fixing plate, a disassembly assembly, and a handle adjustment assembly; The lower part of the fixing plate is provided with a disassembly assembly, and two mounting posts are symmetrically installed on the upper surface of the fixing plate. The upper ends of the two mounting posts are jointly installed with a fixing post, and the fixing post is provided with a grip adjustment assembly. The grip adjustment assembly includes a first bolt and sleeves slidably fitted onto both ends of a fixed post. The sleeves have multiple evenly arranged first positioning holes. Both ends of the fixed post have first insertion holes. The first bolt passes through the corresponding first positioning hole and first insertion hole. A second nut is threaded onto the lower end of the first bolt. A connecting bracket is mounted on the upper surface of the sleeve. A rack is mounted at the end of the connecting bracket. A rotating shaft is rotatably mounted in the middle of the fixed post. A gear is mounted on the upper end of the rotating shaft. Two racks are located on either side of the gear, and the gear and racks are meshed together. A drive assembly is mounted on the upper surface of the fixed plate, and the drive assembly is connected to the rotating shaft.

[0007] Furthermore, the disassembly assembly includes a second bolt and a slide rail on the lower surface of the fixed plate. A movable clamping plate is slidably installed in the slide rail. A fixed clamping plate is installed on the right side of the lower surface of the fixed plate. The lower ends of both the movable clamping plate and the fixed clamping plate are bent inward. A hydraulic cylinder is installed on the left inner wall of the slide rail. The outer end of the piston rod of the hydraulic cylinder is fixedly connected to the movable clamping plate. A plurality of second positioning holes are evenly provided on the side of the fixed plate. A second insertion hole is provided on the side of the movable clamping plate. The second bolt passes through the corresponding second positioning hole and the second insertion hole. A first nut is threaded onto the other end of the second bolt.

[0008] First, separate the second bolt and the first nut. Then, pull the second bolt out of the corresponding second positioning hole and second insertion hole. Next, start the hydraulic cylinder to move the movable clamping plate. Adjust the distance between the movable clamping plate and the fixed clamping plate by comparing the distance between the two fixing holes on the X-ray tube's sealing ring. Insert the movable clamping plate and the fixed clamping plate into the corresponding fixing holes and clamp them together. Then, pass the second bolt through the corresponding second positioning hole and second insertion hole, and then thread the second bolt and the first nut together to fix the movable clamping plate. Finally, the user can grip the sleeve and rotate it to remove the X-ray tube's sealing ring. This design achieves universality for disassembling and installing sealing rings of different diameters, making it convenient for engineers to carry and use, and improving work efficiency.

[0009] Furthermore, the drive assembly includes a motor bracket mounted on the upper surface of a fixed plate, on which a motor is mounted. The output shaft of the motor is connected to the lower end of a rotating shaft via a coupling, and the input end of the motor is electrically connected to the output end of an external controller. The external controller controls the motor's operation, which in turn drives the rotating shaft to rotate, thus electrically completing the rotation of the shaft.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: The disassembly device for the sealing ring of this X-ray tube allows for adjustment of the distance between the outer ends of the two sleeves according to the user's arm length and working status. This design not only saves the user's effort but also improves the user's comfort. Activating the drive assembly causes the rotating shaft to rotate forward or backward. The rotating shaft rotates the gear, which meshes with two racks. Due to the forward or reverse rotation of the rotating shaft, the two racks move in opposite directions or relative to each other. The racks drive the corresponding sleeves to move, thereby adjusting the distance between the two sleeves. Then, the first bolt is inserted into the first positioning hole and the first insertion hole and threadedly connected to the second nut, which can fix the sleeve and ensure its stability. Then, the movable clamping plate and the fixed clamping plate of the disassembly assembly are clamped together. Next, the second bolt is passed through the corresponding second positioning hole and the second insertion hole. Then, the second bolt and the first nut are threaded together to fix the movable clamping plate. Finally, the user grips the sleeve and rotates it to remove the sealing ring of the X-ray tube. This design realizes the universality of disassembling and installing sealing rings of different diameters, which is convenient for engineers to carry and use, and improves work efficiency.

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] Please see Figure 1-2 This embodiment provides a technical solution: a device for disassembling the sealing ring of an X-ray tube, including a fixing plate 1, a disassembly assembly and a handle adjustment assembly; The lower part of the fixing plate 1 is provided with a disassembly assembly. Two mounting posts 12 are symmetrically installed on the upper surface of the fixing plate 1. A fixing post 15 is installed at the upper end of the two mounting posts 12. A handle adjustment assembly is provided on the fixing post 15. The grip adjustment assembly includes a first bolt 6 and sleeves 4 slidably fitted at both ends of a fixed post 15. Multiple evenly arranged first positioning holes 5 are provided on the sleeves 4. First insertion holes are provided at both ends of the fixed post 15. The first bolt 6 passes through the corresponding first positioning hole 5 and first insertion hole. A second nut is threaded onto the lower end of the first bolt 6. A connecting bracket 11 is mounted on the upper surface of the sleeve 4. A rack 9 is mounted at the end of the connecting bracket 11. A rotating shaft 16 is rotatably mounted in the middle of the fixed post 15. A gear 8 is mounted on the upper end of the rotating shaft 16. Two racks 9 are located on either side of the gear 8, and the gear 8 and rack 9 are meshed together. A drive assembly is mounted on the upper surface of the fixed plate 1, and the drive assembly is connected to the rotating shaft 16.

[0015] In use, firstly, separate the first bolt 6 and the second nut, then pull the first bolt 6 out of the corresponding first positioning hole 5 and the first insertion hole. Then, adjust the distance between the outer ends of the two sleeves 4 according to the user's arm length and working status. This setting not only saves the user's strength but also improves the user's comfort. Start the drive assembly to drive the rotating shaft 16 to rotate forward or backward. The rotation of the rotating shaft 16 drives the gear 8 to rotate. The gear 8 meshes with the two racks 9. Because the rotating shaft 16 rotates forward or backward, the two racks 9 move in opposite directions or relative to each other. The racks 9 drive the corresponding sleeves 4 to move, thereby adjusting the distance between the two sleeves 4. Then, insert the first bolt 6 into the first positioning hole 5 and the first insertion hole and thread it with the second nut to fix the sleeve 4 and ensure its stability.

[0016] The disassembly assembly includes a second bolt 14 and a slide rail 18 on the lower surface of the fixed plate 1. A movable clamping plate 3 is slidably installed in the slide rail 18. A fixed clamping plate 13 is installed on the right side of the lower surface of the fixed plate 1. The lower ends of both the movable clamping plate 3 and the fixed clamping plate 13 are bent, and the bending direction is inward. A hydraulic cylinder 17 is installed on the left inner wall of the slide rail 18. The outer end of the piston rod of the hydraulic cylinder 17 is fixedly connected to the movable clamping plate 3. Multiple second positioning holes are evenly opened on the side of the fixed plate 1. A second insertion hole is opened on the side of the movable clamping plate 3. The second bolt 14 passes through the corresponding second positioning hole and the second insertion hole. A first nut 2 is threaded onto the other end of the second bolt 14.

[0017] First, separate the second bolt 14 and the first nut 2. Then, pull the second bolt 14 out of the corresponding second positioning hole and the second insertion hole. Next, start the hydraulic cylinder 17 to drive the movable clamping plate 3 to move. By comparing the distance between the two fixing holes on the sealing ring of the X-ray tube, adjust the distance between the movable clamping plate 3 and the fixed clamping plate 13. Insert the movable clamping plate 3 and the fixed clamping plate 13 into the corresponding fixing holes respectively. Clamp the movable clamping plate 3 and the fixed clamping plate 13 together. Next, use the second bolt 14 to pass through the corresponding second positioning hole and the second insertion hole. Then, the second bolt 14 and the first nut 2 are threaded together to fix the movable clamping plate 3. Finally, the user can grip the sleeve 4 and rotate it to remove the sealing ring of the X-ray tube. This design realizes the universality of disassembling and installing sealing rings of different diameters, which is convenient for engineers to carry and use, and improves work efficiency.

[0018] The drive assembly includes a motor bracket 7 mounted on the upper surface of the fixed plate 1, on which a motor 10 is mounted. The output shaft of the motor 10 is connected to the lower end of the rotating shaft 16 via a coupling. The input end of the motor 10 is electrically connected to the output end of an external controller. The external controller controls the operation of the motor 10, which drives the rotating shaft 16 to rotate, thereby completing the rotation of the rotating shaft 16 electrically.

[0019] The working principle of the X-ray tube sealing ring disassembly device provided by this utility model is as follows: In use, firstly, the first bolt 6 and the second nut are separated, and then the first bolt 6 is pulled out of the corresponding first positioning hole 5 and the first insertion hole. Then, according to the user's arm length and working state, the distance between the outer ends of the two sleeves 4 is adjusted. This setting not only saves the user's strength but also improves the user's comfort. The drive component is started to drive the rotating shaft 16 to rotate forward or backward. The rotation of the rotating shaft 16 drives the gear 8 to rotate. The gear 8 is connected to the two racks 9 through meshing. Because the rotating shaft 16 rotates forward or backward, the two racks 9 move in opposite directions or relative to each other. The racks 9 drive the corresponding sleeves 4 to move, thereby adjusting the distance between the two sleeves 4. Then, the first bolt 6 is inserted into the first positioning hole 5 and the first insertion hole and threadedly connected to the second nut to fix the sleeve 4 and ensure its stability. First, separate the second bolt 14 and the first nut 2. Then, pull the second bolt 14 out of the corresponding second positioning hole and second insertion hole. Next, start the hydraulic cylinder 17 to move the movable clamping plate 3. Adjust the distance between the movable clamping plate 3 and the fixed clamping plate 13 by comparing the distance between the two fixing holes on the X-ray tube's sealing ring. Insert the movable clamping plate 3 and the fixed clamping plate 13 into the corresponding fixing holes and clamp them together. Then, pass the second bolt 14 through the corresponding second positioning hole and second insertion hole, and thread the second bolt 14 and the first nut 2 to fix the movable clamping plate 3. Finally, the user grips the sleeve 4 and rotates it to remove the X-ray tube's sealing ring. This design achieves universality for disassembling and installing sealing rings of different diameters, making it convenient for engineers to carry and use, and improving work efficiency. The motor 10 is controlled by an external controller, which drives the rotating shaft 16 to rotate, thus completing the rotation of the rotating shaft 16 electrically.

[0020] It is worth noting that in this embodiment, the core chip of the external controller is an STC microcontroller, specifically the STC15W204S. The motor 10 and hydraulic cylinder 17 can be freely configured according to the actual application scenario. The external controller controls the operation of the motor 10 and hydraulic cylinder 17 using methods commonly used in the prior art, and the content not described in detail in this specification belongs to the prior art known to those skilled in the art.

[0021] The above are merely embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
