[0002] In the field of aero-engine manufacturing, as one of the core components, the surface quality of the cylinder block directly affects the overall performance, service life and flight safety of the engine. Among them, the cylinder block needs to withstand extreme conditions such as high temperature, high pressure and high-speed operation, and at the same time, it also needs to have good corrosion resistance, wear resistance and electrical conductivity.

[0035] Embodiment 1: Please refer to Figures 1 - 7 As shown, this embodiment provides an intelligent electroplating device for an aero-engine cylinder block, including side plates 1. A bottom plate 2 is arranged at the bottom of the side plates 1. Fixing plates 12 are arranged on both sides of the side plates 1. A clamping device 3 for fixing the inlet and outlet of the deep hole of the cylinder block is arranged inside the fixing plates 12. A second sliding column 36 for adjusting the position of the inlet and outlet of the deep hole of the engine cylinder block is arranged inside the clamping device 3. A threaded projection 371 for clamping the upper and lower ends of the cylinder block is arranged inside the clamping device 3. A sliding device 4 for adjusting the angle of the engine cylinder block is arranged on the top of the bottom plate 2. A rotating assembly 45 is arranged inside the sliding device 4. Among them: By sliding the clamping device 3, the clamping of the engine cylinder block is completed by using the threaded projection 371 and the second sliding column 36. At the same time, the adjustment of the angle and position of the cylinder block is completed by using the sliding device 4 and the rotating assembly 45. One side of the side plate 1 is fixedly connected with a first slide rail 11. Fixing plates 12 are arranged on both sides of the side plate 1. The bottom of the side plate 1 is fixedly connected with a bottom plate 2. Side columns 21 are fixedly connected to both sides of the bottom plate 2. A motor 211 is fixedly connected to the outside of the side column 21. The output end of the motor 211 is fixedly connected with a first threaded rod 212. A second slide rail 22 is fixedly connected to the top of the bottom plate 2;

[0036] Among them, the second slide rail 22 is an electric slide rail. The second slide rail 22 protrudes on the top of the bottom plate 2, and the side of the second slide rail 22 is in contact with the outer walls of the two side wheels 333. This makes the side wheels 333 rotate on one side of the second slide rail 22.

[0037] As Figures 3 - 6As shown, the clamping device 3 includes a sliding connection member 31. A triangular groove 311 is formed on one side of the sliding connection member 31. One side of the sliding connection member 31 is slidably connected to one side of the first slide rail 11. A fixing member 32 is fixedly connected to the side of the sliding connection member 31 away from the first slide rail 11. The sliding connection member 31 is fixedly connected to the fixing member 32. A fixing column 33 is fixedly connected to the side of the fixing member 32 away from the sliding connection member 31. A first rotating rod 331 is provided at the central position of the fixing column 33. Among them: The lower end of the first rotating rod 331 is fixedly connected to a second threaded rod 332. A rotating wheel 333 is fixedly connected to the end of the second threaded rod 332 away from the first rotating rod 331. A first sliding column 34 is slidably connected to the outer wall of the fixing column 33. A square groove 341 is formed inside the first sliding column 34. The top end of the first rotating rod 331 is rotatably connected to the inside of the square groove 341. A first turntable 35 is rotatably connected to the side of the first sliding column 34 away from the fixing column 33. A second sliding column 36 is slidably connected to the outer wall of the first turntable 35. A triangular protrusion 361 is fixedly connected to the top of the second sliding column 36. A fixing ring 362 is fixedly connected to the side of the second sliding column 36 away from the triangular protrusion 361. A second turntable 37 is rotatably connected to the inside of the fixing plate 12. A second rotating rod 371 is fixedly connected to the central position of the second turntable 37. A threaded protrusion 3711 is fixedly connected to the outer wall of the second rotating rod 371. A fixing disk 39 is fixedly connected to the end of the second rotating rod 371 away from the second turntable 37. The sliding connection member 31 is threadedly connected to the first threaded rod 212.

[0038] A second turntable 37 is rotatably connected to the inside of the fixing plate 12. A second rotating rod 371 is fixedly connected to the central position of the second turntable 37. A threaded protrusion 3711 is fixedly connected to the outer wall of the second rotating rod 371. A fixing disk 39 is fixedly connected to the end of the second rotating rod 371 away from the second turntable 37. Among them: A square rotating wheel 38 is fixedly connected to the outer wall of the second rotating rod 371. A square plate 381 is fixedly connected to one side of the square rotating wheel 38. A misaligned rod 382 is fixedly connected to the middle end of the square plate 381.

[0039] It can be seen from this that when electroplating the deep holes of the engine block is required, as Figures 1 - 5 shown, during the installation process, the staff first connect the two second sliding columns 36 to the external electroplating solution equipment, and then the staff operate the robotic arm to place the engine block on the placement plate 43;

[0040] At this time, driven by the motor 211, the first threaded rod 212 rotates. At the same time, with the rotation of the first threaded rod 212, the sliding connector 31 moves left and right on the outer wall of the first threaded rod 212, and at the same time drives the fixing member 32, the fixing column 33, the first sliding column 34 and the second sliding column 36 to move left and right. At the same time, the second sliding column 36 slides inward, causing the fixing rings 362 on both sides to slide inward, fixing the positions on both sides of the deep hole of the cylinder block inside the fixing rings 362. At the same time, the fixing rings 362 are used for sealing and the upper fixing plate 39 is used to fix the engine cylinder block. At the same time, during the rotation of the second rotating rod 371 and the threaded projection 3711 under electric drive, the triangular projection 361 slides in the thread groove of the threaded projection 3711, and gradually drives the triangular projection 361 and the sliding column 36 to slide left and right. At this time, the second sliding columns 36 on both sides slide inward simultaneously, fix and seal the deep holes on both sides of the cylinder block, and connect the pipelines on both sides with the deep holes. After the liquid required for electroplating in the peripheral equipment is injected into the deep holes inside, electricity is applied in the second sliding column 36, so that a reaction occurs between the solution in the deep hole of the cylinder block and the corresponding solution. After a period of reaction, the internal solution is discharged, and pure water is replaced to clean the solution in the previous round. Finally, the electroplating of the deep hole of the engine cylinder block is completed;

[0041] It should be noted that the initial position of the runner 333 is above the bottom plate 2 and is in contact with one side of the second slide rail 22. During the process of the first threaded rod 212 driving the sliding connector 31 to move left and right, the runner 333 will rotate due to friction. During the rotation of the runner 333, the second threaded rod 332 will be driven to rotate, and the runner 333, the second threaded rod 332 and the first sliding column 34 will move up and down. At this time, the upward moving first sliding column 34 will drive the second sliding column 36 to move upward, so that the triangular projection 361 penetrates into the thread groove of the threaded projection 3711. At this time, driven by the disc motor between the second turntable 37 and the fixing plate 12, the second rotating rod 371 and the threaded projection 3711 rotate, so that the triangular projection 361 slides in the threaded projection 3711, drives the sliding column 36 to slide left and right through the threaded projection 3711, and completes the sealing and fixing of the deep hole of the cylinder block by the fixing rings 362 on both sides.

[0042] Embodiment 2: As Figure 7As shown, the sliding device 4 includes a sliding plate 41. The sliding plate 41 is slidably connected to the top of the second slide rail 22. A third turntable 42 is rotatably connected to the top of the sliding plate 41. A placement plate 43 is slidably connected to the top of the third turntable 42. A first extension rod 44 is fixedly connected to the top of one side of the sliding plate 41. A rotating assembly 45 is disposed through the first extension rod 44. Among them: The rotating assembly 45 includes a sliding block 451. A rotating member 452 is fixedly connected to the top of the sliding block 451. The rotating member 452 is fixedly connected to the sliding block 451. The rotating member 452 passes through the first extension rod 44. A second extension rod 46 is fixedly connected to the top of one side of the bottom plate 2. A second arched hole 461 is formed in the outer wall of the second extension rod 46. A third extension rod 47 is fixedly connected to the top of one side of the bottom plate 2. A connecting rod 48 is disposed between the second extension rod 46 and the third extension rod 47. One end of the connecting rod 48 is rotatably connected to one end of the third extension rod 47. The other end of the connecting rod 48 is slidably connected to the second arched hole 461 in the second extension rod 46. The inner side of the sliding block 451 is slidably connected to the outer wall of the connecting rod 48.

[0043] It can be seen from this that when it is necessary to adjust the position and angle of the engine block, as Figure 7 shown, driven by the electric second slide rail 22, the sliding plate 41 slides inward, and at the same time drives the first extension rod 44 to slide to one side. At this time, the connecting rod 48 between the third extension rod 47 and the second extension rod 46 slides to the left in the second arched hole 461, and drives the first extension rod 44 to slide a short distance to one side. At the same time, by the sliding of the sliding plate 41, the position of the engine block together with the clamping device 3 will be slid to the same side, so as to adjust the position of the entire engine block.

[0044] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art of this industry should understand that the present invention is not limited by the above embodiments. The above embodiments and the descriptions in the specification are only preferred examples of the present invention, and are not used to limit the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed.
