Description

Technical Field

[0001] The utility model relates to the technical field of turbochargers, and more specifically, to a turbocharger that is convenient to fix. Background Technique

[0002] A turbocharger is a device used to increase the power of an internal combustion engine. It utilizes the energy of the exhaust gas discharged from the engine to drive the turbine to rotate, and then drives the coaxial compressor impeller to rotate. After compressing the air, it is sent into the engine cylinder to increase the intake air volume. The turbocharger is usually installed between the intake system and the exhaust system of the engine. The exhaust system is connected to the exhaust manifold of the engine to receive the exhaust gas energy, and the intake system is connected to the intake pipe to send the compressed air into the engine cylinder. The installation position of the turbocharger will vary according to the type, structure, and design requirements of the engine.

[0003] For the existing turbocharger, a large number of screws and bolts are usually used for installation and fixation. When the turbocharger needs to be disassembled and repaired, a large number of screws and bolts need to be disassembled. When installing after the repair is completed, the screws and bolts need to be installed again. The disassembly and installation are relatively troublesome. In addition, the disassembly and installation will cause the screws and bolts to become loose, resulting in the insecure installation of the turbocharger. In view of this, we propose a turbocharger that is convenient to fix. Content of the Utility Model

[0023] Please refer to Figures 1-4 , the present utility model provides a technical solution:

[0024] A turbocharger that is convenient to fix, including the turbocharger main body 1. Specifically, a screw post 2 is welded to the bottom of the turbocharger main body 1. A column barrel 4 is sleeved on the outer circumferential wall of the screw post 2. An external thread is provided on the outer circumferential wall of the screw post 2, and an internal thread matching the screw post 2 is provided on the inner circumferential wall of the column barrel 4. By rotating the column barrel 4, the column barrel 4 is tightly connected to the screw post 2. Two limiting blocks 5 are welded to the circumferential side wall of the column barrel 4. A rotating column 6 is welded to the bottom of the column barrel 4. A rotating bearing 7 is welded to the bottom of the rotating column 6. A base 8 is welded to the bottom of the rotating bearing 7. The rotating bearing 7 is an existing part in the example. The rotating column 6 can rotate by itself through the rotating bearing 7. A fixing plate 9 is welded to the top surface of the base 8. Multiple bolt holes are provided in the fixing plate 9, and the fixing plate 9 is fixed by bolts. Four sliding columns 10 and four springs 12 are welded to the top surface of the base 8. A limiting plate 11 is welded to the top surface of the sliding column 10. A braking plate 13 is welded to the top surface of the spring 12. A sliding hole 14 matching the sliding column 10, a column hole 15 matching the column barrel 4, and a limiting hole 16 matching the limiting block 5 are provided in the braking plate 13 from top to bottom. Under the elastic force of four groups of springs 12, the braking plate 13 will move upward along the sliding column 10 until it is restricted by the limiting plate 11 at the top of the sliding column 10, so that the braking plate 13 abuts against the bottom surface of the limiting plate 11. At this time, the limiting hole 16 of the braking plate 13 just engages with the limiting block 5, and the column barrel 4 is restricted by the limiting block 5 and cannot rotate. When installing or disassembling the turbocharger main body 1, only need to press the braking plate 13 downward, so that the braking plate 13 moves downward along the sliding column 10, further making the limiting block 5 leave the limiting hole 16, and then by rotating the column barrel 4, the column barrel 4 is connected or separated from the screw post 2, and the turbocharger main body 1 is installed or disassembled. The installation and disassembly are extremely convenient, and each time of disassembly only needs to adjust the column barrel 4 and the screw post 2, while the bottom fixing plate 9 is fixed by bolts and does not need to disassemble the bolts of the fixing plate 9, and there will be no phenomenon of bolt loosening caused by disassembly, making the device firmly fixed.

[0025] It should be noted that in order to make the connection between the column barrel 4 and the screw post 2 firm, a washer 3 is sleeved on the outer circumferential side wall of the screw post 2, and the washer 3 is made of rubber.

[0026] It should be noted that in order to make the spring 12 durable, the spring 12 is made of high-carbon steel, has the characteristics of high temperature resistance, high elasticity and high strength, and an anti-rust paint is applied on the outer surface. The elastic force value of the spring is 27 Newtons.

[0027] In addition, in order to make the material of the braking plate 13 strong, the braking plate 13 is made of steel, with a thickness of 1.8 cm and a bottom surface diameter of 15 cm. The braking plate is sleeved on the outer circumferential wall of the column barrel.

[0028] Finally, in order for the sliding posts 10 and the limiting plates 11 to be made of strong materials and be able to withstand the force brought by the braking plate 13, multiple sliding posts 10 and limiting plates 11 are made of steel. The diameter of the bottom circle of the sliding post 10 is 1.5 cm, and the diameter of the bottom circle of the limiting plate 11 is 2.3 cm.

[0029] Working principle: When this device needs to be used, the fixing plate 9 is installed and fixed by bolts. The braking plate 13 is pressed downward, so that the braking plate 13 moves downward along the sliding post 10, further causing the limiting block 5 to leave the limiting hole 16. Then, by rotating the column barrel 4, the column barrel 4 is connected to the screw column 2 to install the turbocharger main body 1. After the installation is completed, only need to release the braking plate 13. The braking plate 13 is subjected to the elastic force of the four groups of springs 12 and will move upward along the sliding post 10 until it is restricted by the limiting plate 11 at the top of the sliding post 10, so that the braking plate 13 abuts against the bottom surface of the limiting plate 11. At this time, the limiting hole 16 of the braking plate 13 just engages with the limiting block 5, and the column barrel 4 is restricted by the limiting block 5 and cannot rotate. When it is necessary to disassemble the turbocharger main body 1, similarly, only need to press the braking plate 13 downward, and then rotate the column barrel 4 to separate the column barrel 4 from the screw column 2.
