Description

Technical Field

[0002] Turbochargers are divided into four types: mechanical supercharging, air wave supercharging, exhaust gas supercharging, and compound supercharging. Turbocharging increases the engine's intake volume by compressing air, thereby increasing the engine's power and torque. The turbine impeller is a rotating power machine that converts the energy of the flowing working fluid into mechanical work.

[0003] When using an existing turbocharger, it is usually necessary to use an output pin to fix the impeller, and the output pin is used to drive the impeller to rotate so that the turbocharger can work. After the output shaft fixes the impeller, the length of the output pin is fixed, and the position of the impeller cannot be adjusted as needed. When the impeller position needs to be adjusted, the entire output pin needs to be removed or replaced, which results in limitations in the use of the output pin and is not convenient enough.

[0004] Therefore, those skilled in the art provide a turbocharger impeller output pin to solve the problems raised in the above background technology. Utility Model Content

[0008] As a further solution of the utility model: the inner wall of the fixed tube is fixedly connected with a fixing frame, and the front side of the fixing frame is fixedly connected with a limiting ring.

[0009] As a further solution of the utility model: the outer surface of the output pin is fixedly connected with anti-slip strips arranged at equal distances, and each of the anti-slip strips needs to be in the shape of soft rubber.

[0010] As a further solution of the utility model: the upper surface and the bottom surface of the sliding serrated plate are fixedly connected with reinforcement frames, and the right sides of the two reinforcement frames are fixedly connected to the outer surfaces of the output pins.

[0011] As a further solution of the utility model: the outer surface of the rotating pin is rotatably connected with a stabilizing ring, and the bottom surface of the stabilizing ring is fixedly connected to the inner bottom wall of the groove plate.

[0012] As a further solution of the utility model: the outer surface of the rotating pin is sleeved with a limit cover, and the bottom surface of the limit cover is in contact with the inner wall of the fixed tube.

[0013] As a further solution of the utility model: two fixing threaded pins are arranged above the limiting cover, and the bottom ends of the two fixing threaded pins both penetrate the limiting cover and extend to the inside of the fixing tube.

[0024] Specifically, the inner wall of the fixed pipe 1 is fixedly connected with a fixing frame 4 , and the front side of the fixing frame 4 is fixedly connected with a limiting ring 5 .

[0025] Through the above technical solution, by providing the fixing frame 4, the limiting ring 5 can be fixed in the fixing tube 1, so that the limiting ring 5 can limit the output pin 2.

[0026] Specifically, the outer surface of the output pin 2 is fixedly connected with anti-slip strips 9 arranged at equal distances, and each anti-slip strip 9 needs to be in the shape of soft rubber.

[0027] Through the above technical solution, by providing the anti-slip strip 9, the friction force when the impeller is fixed can be increased, thereby improving the stability of the impeller when in use.

[0028] Specifically, the upper surface and the bottom surface of the sliding serrated plate 10 are both fixedly connected with the reinforcement frames 7 , and the right sides of the two reinforcement frames 7 are both fixedly connected with the outer surfaces of the output pins 2 .

[0029] Through the above technical solution, by providing the reinforcement frame 7, the sliding serrated plate 10 can be reinforced on the output pin 2, thereby improving the firmness of the connection.

[0030] Specifically, the outer surface of the rotating pin 8 is rotatably connected with a stabilizing ring 12 , and the bottom surface of the stabilizing ring 12 is fixedly connected to the inner bottom wall of the groove plate 6 .

[0031] Through the above technical solution, by providing a stabilizing ring 12, it can be fixed to the groove plate 6 and limit the rotating pin 8, thereby improving the stability of the rotating pin 8.

[0032] Specifically, a limiting cover 14 is sleeved on the outer surface of the rotating pin shaft 8 , and the bottom surface of the limiting cover 14 contacts the inner wall of the fixed tube 1 .

[0036] The working principle of the utility model is as follows: when in use, first, the impeller is fixed on the output pin 2, and the fixed tube 1 is fixed on the turbocharger. When the fixing is completed, if the position of the impeller needs to be changed, the rotating pin shaft 8 is rotated forward or reversely. The forward or reverse rotation of the rotating pin shaft 8 drives the gear 11 to follow the forward or reverse rotation, and the forward or reverse rotation of the gear 11 drives the sliding sawtooth plate 10 to slide forward or backward in the groove plate 6. When the sliding sawtooth plate 10 slides, the output pin 2 is driven to extend and retract in the fixed tube 1. When the output pin 2 is extended and retracted, the sliding column 3 is driven to move in the fixed tube 1. Follow the movement and install the counterweight plate in the counterweight groove 15 so that the sliding column 3, the groove plate 6 and the sliding serrated plate 10 can have the same weight to prevent the output pin 2 and the fixed tube 1 from shaking when driving the impeller to rotate. When the output pin 2 drives the impeller to adjust the rear position, the limit cover 14 is sleeved on the rotating pin shaft 8, and the limit cover 14 is in contact with the fixed tube 1. Then the fixed threaded pin 13 is rotated to penetrate the limit cover 14 and the fixed tube 1, and fixed in the fixed tube 1, so that the limit cover 14 limits the rotating pin shaft 8 to prevent the rotating pin shaft 8 from rotating, thereby improving the convenience of using the output pin 2.

Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
