Technical Field
[0001] This utility model relates to the field of turbocharger technology, specifically a twin-scroll turbocharger with a positioning structure. Background Technology
[0002] A turbocharger is a device that uses the exhaust gas from an engine to drive a turbine to rotate, which in turn drives a coaxial compressor to compress air and increase the amount of air entering the engine. It can increase power output by about 30%-50% without increasing engine displacement, while reducing fuel consumption and exhaust emissions. It is widely used in automobiles, ships and other fields and is one of the key technologies for achieving high-efficiency power in modern internal combustion engines.
[0003] Turbochargers can be classified into single-scroll turbochargers, twin-scroll turbochargers, and variable geometry turbochargers according to their structure and technology. Among them, twin-scroll turbochargers reduce cylinder exhaust interference and improve engine low-end torque and response speed by dividing the exhaust port into two sets of scrolls.
[0004] Twin-scroll turbochargers are typically used in conjunction with pipelines, which are secured using connecting flanges and bolts. However, during installation, it is necessary to continuously adjust the intake port of the twin-scroll turbocharger and the pipeline to ensure that their contact positions are aligned, making the installation process rather cumbersome.

[0009] Preferably, a friction block is fixed to the end of the bolt; the sidewall of the friction block is provided with multiple protrusions; by adding the friction block, the bolt can be rotated faster, so that it can generate rotational force after contacting the protrusions itself.
[0010] Preferably, a filter plate is provided inside the intake pipe; the filter plate is connected to the intake pipe through an installation assembly; by adding a filter plate, the passing airflow can be filtered, thereby increasing the protection of the twin-scroll turbocharger body.

Detailed Implementation
[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.
[0024] Specific implementation examples are given below.
[0025] like Figures 1 to 5As shown in the figure, a twin-scroll turbocharger with a positioning structure according to an embodiment of the present invention includes a twin-scroll turbocharger body 1, an air inlet 101 on one side wall of the twin-scroll turbocharger body 1, and an exhaust outlet 107 on the other side of the twin-scroll turbocharger body 1; an air inlet pipe 105 and an exhaust pipe 106 are sequentially arranged on the outer wall of the twin-scroll turbocharger body 1; the air inlet pipe 105 and the air inlet 101 are correspondingly arranged; the exhaust outlet 106... The intake 107 and exhaust 106 are correspondingly arranged; the ends of the intake pipe 105, intake port 101, exhaust pipe 106, and exhaust port 107 are all fixedly connected to a connecting flange 108; an adjusting ring 102 is provided on the outer wall of the connecting flange 108; a positioning groove 103 is opened on the inner wall of the adjusting ring 102; a bolt 104 is threadedly connected to the top of the adjusting ring 102; during operation, when connecting, the adjusting ring 102 is first placed on the intake port 101, so that the connecting flange 107 is aligned with the intake port 106. 8. Enter the positioning groove 103, and then insert the air intake pipe 105 into the positioning groove 103. At this time, it is tightly attached, and then the bolt 104 is rotated. During the rotation, the bolt 104 will continuously tighten the adjusting ring 102. During the tightening, the connecting flange 108 at the connection point will be adjusted, so that the connection point is continuously moved and finally overlapped. At this time, the connecting flange 108 can be fixed to connect the air intake port 101 and the air intake pipe 105. At the same time, the exhaust pipe 106 and the exhaust port 107 are fixed in the same way. Thus, when connecting the air intake port 101 and the air intake pipe 105, the connection speed is accelerated by the quick positioning of the adjusting ring 102. By adding the adjusting ring 102, when connecting and fixing the air intake port 101 and the air intake pipe 105, the tightening adjustment of the adjusting ring 102 can quickly overlap the connecting flange 108 between the air intake port 101 and the air intake pipe 105, thereby reducing the set time and increasing the installation positioning of the connecting flange 108.
[0026] like Figures 1 to 4 As shown, the bolt 104 is threaded with a first nut 2 and a second nut 21 in sequence at its end; the first nut 2 and the second nut 21 are in contact; during operation, when adjusting the connecting flange 108 with the adjusting ring 102, the bolt 104 rotates and aligns the connecting flange 108. At this time, after the bolt 104 rotates, the first nut 2 and the bolt 104 can be connected for initial fixation, and then the second nut 21 is installed for secondary fixation, thus making the use of the adjusting ring 102 more stable; by adding the first nut 2 and the second nut 21, the bolt 104 can be locked after use, increasing the stability after the bolt 104 stops, thus making the bolt 104 more stable after fixing the adjusting ring 102.
[0027] like Figures 3 to 4As shown, a friction block 3 is fixed to the end of the bolt 104; the sidewall of the friction block 3 is provided with multiple protrusions; during operation, when the bolt 104 is rotated, it can contact the friction block 3. Since there are many protrusions on the surface of the friction block 3, the rotational thrust can be increased through the position of the protrusions when it contacts the friction block 3; by adding the friction block 3, the bolt 104 can be rotated faster, so that it can generate rotational force after contacting the protrusions itself.
[0028] like Figures 3 to 5 As shown, a filter plate 4 is provided inside the intake pipe 105; the filter plate 4 is connected to the intake pipe 105 through the mounting assembly 41; during operation, the filter plate 4 can be installed inside the intake pipe 105 through the mounting assembly 41 so that it filters the airflow when the intake pipe 105 is working, thereby reducing the amount of dust in the airflow entering the twin-scroll turbocharger body 1; by adding the filter plate 4, the passing airflow can be filtered, thereby increasing the protection of the twin-scroll turbocharger body 1.
[0029] like Figure 5 As shown, the air intake pipe 105 is multi-hole; the mounting assembly 41 includes a spring telescopic rod 5; the spring telescopic rod 5 and the filter plate 4 are fixedly connected; a slider 51 is fixedly connected to the end of the spring telescopic rod 5; a round rod 52 is fixedly connected to the top of the slider 51; the slider 51 is slidably connected to the filter plate 4; a fixing rod 53 is fixedly connected to the side wall of the slider 51; the fixing rod 53 is through-hole and slidably connected to the filter plate 4; the fixing rod 53 and the air intake pipe 105 are slidably fitted; during operation, when... When installing the filter plate 4, first move a pair of sliders 51 towards the center of the filter plate 4. During this movement, the fixing rod 53 will move into the filter plate 4, and at the same time, the spring telescopic rod 5 will be compressed. Then, after placing the filter plate 4 into the air inlet pipe 105, align it with the hole and release the sliders 51. The spring telescopic rod 5 will push the fixing rod 53 into the air inlet pipe 105 for fixing. By using the spring telescopic rod 5 and the fixing rod 53, the filter plate 4 can be quickly fixed, making it more convenient to install the filter plate 4.
[0030] like Figures 3 to 4 As shown, a washer 6 is slidably fitted in the middle of the bolt 104; the washer 6 is located between the first nut 2 and the second nut 21; during operation, when the first nut 2 is installed onto the bolt 104, the washer 6 can be placed on the bolt 104 and then the second nut 21 can be installed onto the bolt 104, causing it to continuously move closer to the washer 6, and finally push the washer 6 into contact with the first nut 2, causing it to continuously compress. When compressed, the washer 6 will deform, and the deformation will increase the friction between the first nut 2 and the second nut 21; by adding the washer 6, the bolt 104 can be more stable when using the first nut 2 and the second nut 21 to fix it, and the deformation increases the friction, thereby reducing shaking.
[0031] Working principle: During connection, first place the adjusting ring 102 onto the air inlet 101, allowing the connecting flange 108 to enter the positioning groove 103. Then, insert the air inlet pipe 105 into the positioning groove 103, ensuring they are tightly fitted. Rotate the bolt 104. During rotation, the bolt 104 continuously tightens the adjusting ring 102, adjusting the connecting flange 108 at the connection point. This causes the connection to move and eventually align, at which point the connecting flange 108 can be fixed, connecting the air inlet 101 and the air inlet pipe 105, while simultaneously venting... The air pipe 106 and exhaust port 107 are fixed in the same way, thus accelerating the connection speed by adjusting the ring 102 for quick positioning when connecting the air inlet 101 and air pipe 105. When adjusting the connecting flange 108 with the adjusting ring 102, the bolt 104 will align the pair of connecting flanges 108 after rotation. At this time, after the bolt 104 is rotated, the first nut 2 can be connected to the bolt 104 for initial fixation, and then the second nut 21 can be installed for secondary fixation, thus making the use of the adjusting ring 102 more stable. When the bolt 104 is rotated, it can contact the friction block 3. Because the friction block 3 has many protrusions on its surface, the rotational thrust can be increased by the protrusions when it comes into contact with the friction block 3. When the intake pipe 105 is working, the filter plate 4 can be installed inside the intake pipe 105 through the mounting assembly 41, so that it filters the airflow when the intake pipe 105 is working, thereby reducing the amount of dust in the airflow entering the twin-scroll turbocharger body 1. When installing the filter plate 4, first move a pair of sliders 51 towards the middle of the filter plate 4. During the movement, the fixing rod 53 will move into the filter plate 4, and at the same time, the spring telescopic rod 5 will be compressed. After placing the filter plate 4 inside the air intake pipe 105, align it with the hole and release the slider 51. The spring extension rod 5 will push the fixing rod 53 into the air intake pipe 105 for fixing. When installing the first nut 2 onto the bolt 104, the washer 6 can be put onto the bolt 104 and then the second nut 21 can be installed onto the bolt 104, so that it moves closer and closer to the washer 6. Finally, push the washer 6 to contact the first nut 2, so that it is continuously squeezed. When squeezed, the washer 6 will deform, and the friction between the first nut 2 and the second nut 21 will increase during deformation.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
