Technical Field

[0001] The utility model belongs to the technical field of aviation equipment maintenance and cleaning, and particularly relates to a plasma cleaning device for an aero-engine. Background Technique

[0002] During the manufacturing and use of aero-engine components, the surface may be eroded by high temperature, high pressure and high-speed air flow, resulting in the formation of oxides and attached pollutants on the surface. These pollutants will affect the working efficiency and service life of the engine, so it is necessary to remove these pollutants through plasma cleaning to improve the performance and safety of the engine.

[0003] In the prior art, plasma cleaning technology utilizes the high energy and chemical reactivity of plasma to completely remove surface pollutants through physical collision, chemical reaction and dissolution. Plasma is an ionized gaseous substance composed of positive and negative ions generated after some electrons are deprived from atoms and atomic groups. Its activity is very high and it can react with pollutants on the material surface to remove them. Usually, aero-engine components are placed on the mesh plate of the rack, and then the rack is sent into the cleaning box for cleaning. However, when encountering components with a large floor area, the position of the mesh plate needs to be adjusted to facilitate the placement of larger components. Usually, before cleaning, the staff needs to pull out the mesh plate from the rack and then insert the mesh plate into the appropriate position. Since the mesh plate is large, it will bring inconvenience to the operation of the staff when handling it, thus affecting the cleaning efficiency of aero-engine components.

[0004] Therefore, there is a need for a plasma cleaning device for an aero-engine to solve the problem that the mesh plate in the cleaning box of aero-engine components is troublesome to adjust in the prior art, which affects the cleaning efficiency. Content of the Utility Model

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0026] Please refer to Figures 1-5 , the present utility model provides a plasma cleaning device for an aeroengine, including a plasma cleaning box 1, and further including:

[0027] Guide rails 7, two guide rails 7 are provided and symmetrically distributed and fixed on the inner bottom wall of the plasma cleaning box 1, and mounting frames 2 are slidably installed on the inner walls of the two guide rails 7, and a bottom plate 4 is fixed to the lower ends of the two mounting frames 2 on the side close to each other;

[0028] Place the placement mesh plate 5. There are multiple placement mesh plates 5, which are respectively slidably installed between two mounting frames 2. Activity through holes 6 are respectively opened in the middle of the surfaces of the two mounting frames 2. Limiting rods 3 are fixed to the inner walls of the two activity through holes 6. Sliders 8 are fixed to both sides of the placement mesh plate 5. The sliders 8 are slidably sleeved on the outer surfaces of the limiting rods 3. A limiting mechanism is provided corresponding to the limiting rod 3 on the side of one of the sliders 8.

[0029] It is worth noting that some debris on the placement mesh plate 5 can be collected through the bottom plate 4. The inner wall of the guide rail 7 is a T-shaped moving groove, and the bottom end of the mounting frame 2 is a T-shaped structure, so as to match the guide rail 7.

[0030] Furthermore, as shown in Figure 1 , Figure 2 and Figure 4 shown, specifically, the limiting mechanism includes:

[0031] A fixing plate 10, the fixing plate 10 is fixed to the side of one of the sliders 8. Two symmetrically distributed L-shaped support blocks 16 are fixed to the top surface of the fixing plate 10. Mounting plates 14 are fixed to the ends of the two L-shaped support blocks 16 close to each other. A chute 13 is opened on the side of the two mounting plates 14 close to each other. A rack plate 15 is slidably arranged between the two mounting plates 14. Limit blocks 18 are fixed to both sides of the rack plate 15. The limit blocks 18 are slidably connected with the chute 13. Limiting holes 9 matching the rack plate 15 are evenly opened on the surface of one of the limiting rods 3;

[0032] A rotating shaft 11, the rotating shaft 11 is rotatably installed on the two L-shaped support blocks 16. A gear 12 is fixedly sleeved on the outer surface of the rotating shaft 11. The gear 12 is in meshing transmission with the rack plate 15.

[0033] It is worth noting that a damping sleeve is fixedly sleeved at the rotating connection of the rotating shaft 11 and the L-shaped support block 16, so as to provide a certain frictional force for the rotating shaft 11, so as to ensure the stability after the rack plate 15 is inserted into the limiting hole 9.

[0034] Furthermore, as shown in Figure 4 and Figure 5 shown, specifically, a turning handle 17 is fixed to the end of the rotating shaft 11. The turning handle 17 facilitates the rotation of the rotating shaft 11; A pull ring 22 is fixed to one side of the placement mesh plate 5. The pull ring 22 facilitates the holding of the placement mesh plate 5.

[0035] Furthermore, as shown in Figure 1 and Figure 3As shown, it is worth specifically stating that a rectangular groove 19 is opened at the lower end of one side of the two mounting brackets 2. A movable rod 21 is inserted into the inner bottom wall of the rectangular groove 19 corresponding to the guide rail 7. Socket holes are opened in the inner wall of the guide rail 7 corresponding to the movable rod 21. When the mounting bracket 2 and the placement mesh plate 5 are located inside the plasma cleaning tank 1, the movable rod 21 is inserted into the socket hole from the rectangular groove 19, thereby limiting the mounting bracket 2 and maintaining the stability of the frame body inside the plasma cleaning tank 1.

[0036] Furthermore, as shown in Figure 1 and Figure 3 As shown, it is worth specifically stating that a lifting ring 20 is fixed to the top end of the movable rod 21. The lifting ring 20 facilitates the holding of the movable rod 21; holding rings 23 are fixed to the outer surfaces of the two mounting brackets 2. The holding rings 23 facilitate the movement of the mounting brackets 2.

[0037] The working process of this solution is as follows: Usually, the parts of the aero-engine are placed on the mesh plate of the frame body, and then the frame body is sent into the cleaning tank for cleaning. However, when encountering parts with a large floor area, it is necessary to adjust the position of the mesh plate to facilitate the placement of larger parts. Usually, before cleaning, the staff needs to pull out the mesh plate from the frame body and then insert the mesh plate into the appropriate position. Since the mesh plate is large, it will bring inconvenience to the operation of the staff when taking and placing, thus affecting the cleaning efficiency of the engine parts. Place the engine parts to be cleaned on the placement mesh plate 5, then close the box door, start the plasma cleaning tank 1, and then clean the parts. Before placing, adjust the distance between the placement mesh plates 5 according to the size of the parts. Pull the placement mesh plate 5 to move inside the mounting bracket 2 through the pull ring 22. The placement mesh plate 5 slides on the limit rod 3 through the slider 8. After adjusting the distance between the placement mesh plates 5, rotate the turning handle 17 to drive the rotating shaft 11 to rotate between the two L-shaped support blocks 16, thereby driving the gear 12 to rotate. Drive the rack plate 15 to move horizontally through the gear 12. When the rack plate 15 moves horizontally, drive the limit block 18 to slide in the chute 13 of the mounting plate 14. Insert the end of the rack plate 15 into the limit hole 9 on one of the limit rods 3, thereby limiting the moved placement mesh plate 5 and facilitating the adjustment of the placement mesh plate 5.

[0038] According to the above working process, it can be seen that: The placement mesh plate 5 facilitates the placement of parts. Through the cooperation of the slider 8, the limit rod 3 and the movable through hole 6, the sliding of the placement mesh plate 5 is facilitated, thereby facilitating the adjustment of the distance between the placement mesh plates 5, and further adapting to the placement of larger parts. Through the cooperation of the limiting mechanism and the placement mesh plate 5, it is convenient to limit the placement mesh plate 5 after moving and adjusting, which facilitates the operation of the staff.
