[0002] The function of a turbocharger is to use the energy of exhaust gas to compress the intake air and send a high-density mixture into the combustion chamber to increase output power. When the turbine rotates using the exhaust gas energy, the turbocharger impeller mounted on the other end of the shaft sends the compressed intake air into the engine. Existing maintenance devices for turbochargers usually use a bench vise to fix the turbocharger when disassembling it. However, due to the irregular shape of the turbocharger, it is difficult to clamp it tightly with a bench vise. Therefore, a maintenance device for turbochargers is proposed. Utility Model Content

[0004] To achieve the above objectives, this utility model provides the following technical solution: a maintenance device for a turbocharger, comprising a base and a hydraulic oil reservoir. Two optical shafts are fixed to the top surface of the base. A bidirectional lead screw is rotatably connected to the top surface of the base. A first handle is fixed to one end of the bidirectional lead screw. Two movable blocks are threaded on the outer side of the bidirectional lead screw. The two movable blocks are slidably connected to the two optical shafts. Multiple mounting holes are provided on opposite sides of the two movable blocks. A movable rod is slidably connected to the inner side of each mounting hole. A spring is fixed to one end of each mounting hole, and one end of the spring is fixedly connected to the inner side of the mounting hole. A connecting groove is provided inside each of the two movable blocks, and the interior of the connecting groove communicates with the interior of the mounting hole. A connecting pipe is fixed between the two movable blocks, and the interior of the connecting pipe communicates with the interior of the hydraulic oil reservoir. The interior of the connecting pipe also communicates with the interior of the connecting groove. A valve is fixed to the outer side of the connecting pipe. A movable plate is provided between the two movable blocks.

[0022] Please see Figures 1 to 4This utility model provides a technical solution: a maintenance device for a turbocharger, including a base 1 and a hydraulic oil reservoir 2. Two optical shafts 3 are fixed on the top surface of the base 1. A double-acting screw 4 is also rotatably connected to the top surface of the base 1. A first handle 5 is fixed to one end of the double-acting screw 4. Two movable blocks 6 are threaded on the outer side of the double-acting screw 4. The two movable blocks 6 are slidably connected to the two optical shafts 3. Multiple mounting holes 7 are opened on the opposite side of the two movable blocks 6. A movable rod 8 is slidably connected to the inner side of the mounting hole 7. A spring 9 is fixed to one end of the mounting hole 7. One end of the spring 9 is fixedly connected to the inner side of the mounting hole 7. A connecting groove 10 is opened inside the two movable blocks 6. The inside of the connecting groove 10 is connected to the inside of the mounting hole 7. A connecting pipe 11 is fixed between the two movable blocks 6. The inside of the connecting pipe 11 is connected to the inside of the hydraulic oil reservoir 2. The inside of the connecting pipe 11 is also connected to the inside of the connecting groove 10. A valve 12 is fixed to the outer side of the connecting pipe 11. A movable plate 13 is provided between the two movable blocks 6.
[0023] The turbocharger is placed on the base 1. Then, the first handle 5 is turned to drive the double-acting screw 4 to rotate. The double-acting screw 4 drives the two movable blocks 6 to move towards the center along the optical axis 3. During this process, some of the movable rods 8 first come into contact with the turbocharger and are squeezed, thus moving towards the interior of the mounting hole 7 and compressing the spring 9. At the same time, the movable rods 8 push the hydraulic oil in the mounting hole 7, and the hydraulic oil enters the connecting groove 10. Then, it enters the hydraulic oil reservoir 2 through the connecting pipe 11 and the valve 12. When all the movable rods 8 are in contact with the outside of the turbocharger, the spring 9 pushes them, causing all the movable rods 8 to be in contact with the outside of the turbocharger. At this time, the valve 12 is closed, cutting off the passage between the connecting groove 10 and the hydraulic oil reservoir 2. By utilizing the incompressible property of liquid, the position of all the movable rods 8 is fixed, keeping the movable rods 8 in contact with the turbocharger. Through the above process, the irregular shape of the turbocharger can be adapted, solving the problem that it is difficult to clamp the turbocharger with a vise when it is fixed due to the irregular shape of the turbocharger.
[0024] Furthermore, multiple through slots are provided on the outer side of the movable plate 13. The inner side of the through slots is slidably connected to the outer side of the movable rod 8. A drive shaft 14 is rotatably connected inside the base 1. A second handle 15 is fixed to one end of the drive shaft 14. Two first connecting rods 16 are fixed to the outer side of the drive shaft 14. A second connecting rod 17 is rotatably connected to one end of each of the two first connecting rods 16. A guide rail 18 is rotatably connected to the upper end of the second connecting rod 17. The guide rail 18 is slidably connected to the base 1. Two third connecting rods 19 are slidably connected to the inner side of the guide rail 18. The middle part of the outer side of the third connecting rod 19 is rotatably connected to the outer side of the base 1. A fourth connecting rod 20 is rotatably connected to the upper end of the third connecting rod 19. One end of the fourth connecting rod 20 is rotatably connected to the outer side of the movable plate 13.
[0025] When a foreign object enters between the movable rods 8, the second handle 15 is rotated. The second handle 15 drives the two first connecting rods 16 to rotate via the transmission shaft 14. The first connecting rods 16 raise the height of the guide rail 18 via the second connecting rod 17. During this process, the guide rail 18 raises the height of the lower end of the third connecting rod 19, causing the third connecting rod 19 to rotate. The third connecting rod 19 pushes the movable plate 13 to move outward along the movable rods 8 via the fourth connecting rod 20, thereby pushing out the foreign object between the movable rods 8, which plays the role of cleaning the foreign object. It is convenient and quick to use.
[0026] The specific usage and function of this embodiment: The present invention places the turbocharger on the base 1, and then rotates the first handle 5 to drive the double-acting screw 4 to rotate. The double-acting screw 4 drives the two movable blocks 6 to move towards the middle along the optical axis 3. During this process, some of the movable rods 8 first come into contact with the turbocharger and are squeezed, thus moving towards the interior of the mounting hole 7 and compressing the spring 9. At the same time, the movable rods 8 push the hydraulic oil in the mounting hole 7. The hydraulic oil enters the connecting groove 10 and then enters the hydraulic oil reservoir 2 through the connecting pipe 11 and the valve 12. When all the movable rods 8 are in contact with the outside of the turbocharger, due to the pushing of the spring 9, all the movable rods 8 are in contact with the outside of the turbocharger. At this time, the valve 12 is closed, so that the passage between the connecting groove 10 and the hydraulic oil reservoir 2 is cut off. By utilizing the incompressible property of liquid, the position of all the movable rods 8 is fixed, so that the movable rods 8 remain in contact with the turbocharger.
[0027] When a foreign object enters between the movable rods 8, the second handle 15 is rotated. The second handle 15 drives the two first connecting rods 16 to rotate through the transmission shaft 14. The first connecting rods 16 raise the height of the guide rail 18 through the second connecting rod 17. During this process, the guide rail 18 raises the height of the lower end of the third connecting rod 19, causing the third connecting rod 19 to rotate. The third connecting rod 19 pushes the movable plate 13 to move outward along the movable rods 8 through the fourth connecting rod 20, thereby pushing out the foreign object between the movable rods 8 and cleaning the foreign object.
[0028] 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.
