[0002] Electron gun maintenance refers to the technical operations of inspecting, cleaning, adjusting, or replacing damaged parts of an electron gun to restore its normal function. Electron guns are widely used in equipment such as cathode ray tubes, electron microscopes, electron beam welding machines, particle accelerators, and X-ray tubes, responsible for emitting and controlling electron beams. Due to prolonged use or improper operation, electron guns may experience problems such as contamination, electrode aging, and vacuum leaks, thus requiring specialized equipment for maintenance.

[0003] Existing technologies employ either an integral track flipping mechanism or a fixed lifting mechanism. For example, Chinese Patent Publication No. CN111846879A discloses a flipping device, including a frame, a track and a flipping mechanism mounted on the frame. The flipping mechanism is located on one side of the track and includes a lifting cylinder, a rotating cylinder, and a finger cylinder. The rotating cylinder is mounted at the end of the lifting cylinder, and a rotating seat is provided on the rotating cylinder. The finger cylinder is mounted on the rotating seat and has a clamp. The flipping mechanism first clamps the workpiece conveyed by the track using the clamp, then raises the clamp to a certain height using the lifting cylinder, then flips the clamp 180° using the rotating cylinder, and finally lowers the clamp using the lifting cylinder to place the workpiece back onto the track for conveying.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0017] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0018] Example: Reference Figures 1-4A flipping device for repairing an electron gun includes a support frame 2, a connecting plate 3 fixedly connected to the surface of the support frame 2, and a base 1 at the bottom of the support frame 2. The base 1 is 500mm wide, 1000mm long, and 50mm thick, and the support frame 2 is 1000mm high. It is made of 50 stainless steel channel steel and stainless steel plate welded together. The base 1 has a rectangular shape for easy placement and maintenance. A rotating shaft 9 is rotatably connected to the connecting plate 3. The center of the rotating shaft 9 is 700mm away from the base 1, and one end of the rotating shaft 9 is vertically fixed. A clamping assembly is fixedly connected to the connecting plate 3 to fix the body of the electron gun. An arc-shaped through hole 4 with the axis of the rotating shaft 9 as the center is opened on the connecting plate 3. A limit post 10 is provided on the clamping assembly. The limit post 10 is slidably connected to the arc-shaped through hole 4. By rotating the clamping assembly 180°, the body of the electron gun can be flipped synchronously. An adjustable locking mechanism is provided on the support frame 2. The locking mechanism locks the angle of the clamping assembly by locking the limit post 10. Then, the locking mechanism locks the limit post 10, thereby achieving the flipping effect of the electron gun for subsequent maintenance.

[0019] In the above solution, the base 1 is designed in a rectangular shape to facilitate placement, maintenance, or relocation, making the maintenance equipment compact and adaptable to different maintenance scenarios. The electron gun body is mounted on the clamping assembly, and then the clamping assembly is supported and rotated 180° by the support frame 2 to achieve flipping. It should be explained that there are two sets of arc-shaped through holes 4, each set of arc-shaped through holes 4 is centered on the axis of the rotating shaft 9. When the support assembly needs to be flipped, the rotating shaft 9 rotates 180°, and the limiting post 10 moves along the arc-shaped through hole 4 from one end to the other. The angle of the clamping assembly is locked by locking the limiting post 10, thereby improving the convenience of the flipping operation, improving work efficiency, and effectively reducing unnecessary damage during equipment maintenance. It also facilitates operation and flipping, reduces manpower, and facilitates electron gun maintenance.

[0020] The clamping assembly includes a first clamping plate 8 and a second clamping plate 12. The rotating shaft 9 and the limiting post 10 are both fixedly connected to the first clamping plate 8. The second clamping plate 12 is detachably connected to the first clamping plate 8. When the two clamping plates are spliced ​​together, the overall length is 400mm. The clamping plate has holes specifically for placing the electronic gun body. The inner diameter of the hole is 260mm, the outer diameter of the hole is 200mm, the inner height is 140mm, and the overall height is 170mm.

[0021] Since it is formed by splicing, in order to improve the stability during connection, a connecting block is fixedly connected to the first clamping plate 8, and a threaded hole 15 is opened on the connecting block. A fixing plate 13 is fixedly connected to the second clamping plate 12, and a locking bolt 14 is provided on the fixing plate 13. The locking bolt 14 cooperates with the threaded hole 15. By tightening the locking bolt 14, its end is connected to the threaded hole 15, thereby fixing the second clamping plate 12 to the first clamping plate 8, achieving a stable connection effect.

[0022] To prevent the electron gun from rotating during maintenance, four positioning holes 16 are provided on the top of the two sets of clamping plates, arranged in a circular pattern.

[0023] Furthermore, the aforementioned locking mechanism may include a locking rod 7, a fixed post 6 fixedly connected to the support frame 2, the locking rod 7 slidably connected to the fixed post 6, and a through hole 11 provided on the rotating shaft 9 and the limiting post 10. The locking rod 7 is detachably connected to the through hole 11, and the locking rod 7 can be inserted into the through hole 11 on the rotating shaft 9 and the limiting post 10 to achieve the effect of limiting the clamping plate. When the locking rod 7 is not needed, it can be removed and stored.

[0024] In addition, the locking mechanism may also include a positioning and fixing hole 5 opened on the connecting plate 3, and a limiting hole that cooperates with the positioning and fixing hole 5 is opened on the outer wall of the first clamping plate 8. By inserting the fixing bolt into the positioning and fixing hole 5 and the limiting hole, the clamping plate can also be limited. The locking rod 7 can be used in conjunction with the fixing bolt or either one alone.

[0025] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
