Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of oil return pipelines, and in particular relates to an oil return pipeline for a turbocharger. Background Art
[0002] A turbocharger is an air compressor that increases the intake volume by compressing air. It uses the inertial force of the exhaust gas discharged by the engine to drive the turbine in the turbine chamber. The turbine in turn drives the coaxial impeller. The impeller presses the air sent from the air filter pipe to pressurize it into the cylinder. When the engine speed increases, the exhaust gas discharge speed and the turbine speed also increase synchronously. The impeller compresses more air into the cylinder. The increased air pressure and density can burn more fuel. Increasing the fuel amount and adjusting the engine speed accordingly can increase the engine's output power. The turbocharger needs to be lubricated with lubricating oil when working, and the oil return line is the basic structural component of the turbocharger.
[0003] A turbocharger is generally composed of a pipe and a connecting end. During production, the end is welded to one end of the pipe. During welding, the two need to be initially fixed by spot welding. However, since the pipe is thin, it is easy to penetrate the pipe during welding, and welding is not convenient at the root of the end. Utility Model Content

[0006] Furthermore, the docking assembly includes a docking tube integrally connected to one end of the oil return pipeline, and one end of the docking tube is fixedly connected to a first flange.
[0007] Furthermore, the insert tube is inserted into the interior of the butt joint tube, the outer diameter of the insert tube is equal to the inner diameter of the butt joint tube, and the inner diameter of the insert tube is equal to the inner diameter of the oil return pipe.
[0008] Furthermore, the structure of the first flange is the same as that of the second flange, one side of the first flange is a slope with an inclination angle of 30°-45°, and the bottom of one side of the first flange is an arc-shaped structure.

[0019] In order to make the purpose and advantages of the utility model more clear, the utility model is specifically described in combination with the following embodiments. It should be understood that the following text is only used to describe one or several specific implementations of the utility model, and does not strictly limit the protection scope of the specific request of the utility model.
[0020] like Figure 1-4As shown, a turbocharger oil return pipeline includes an oil return pipeline 1 and a docking assembly 2, there are two docking assemblies 2, the two docking assemblies 2 are respectively fixedly connected to the two ends of the oil return pipeline 1, one end of the two docking assemblies 2 is welded with a connecting assembly 3, the connecting assembly 3 includes a connecting plate 31, one side of the connecting plate 31 is integrally connected with an insert sleeve 32, one end of the side wall of the insert sleeve 32 is fixedly connected with a second flange 36, the docking assembly 2 includes a docking tube 21 integrally connected to one end of the oil return pipeline 1, one end of the docking tube 21 is fixedly connected with a first flange 23, and the surface of the connecting plate 31 is symmetrically provided with mounting holes 33.
[0021] According to the above structure, during production, the insert 32 is first inserted into the interior of the docking tube 21, the connecting component 3 is docked to one end of the return oil pipeline 1, and then the docking component 2 and the connecting component 3 are welded together. After the docking component 2 and the connecting component 3 are docked, the second flange 36 and the first flange 23 are spliced together. During welding, welding is performed between the first flange 23 and the second flange 36.
[0022] like Figure 2-4 As shown, the insert sleeve 32 is inserted into the interior of the butt-joint pipe 21 , the outer diameter of the insert sleeve 32 is equal to the inner diameter of the butt-joint pipe 21 , and the inner diameter of the insert sleeve 32 is equal to the inner diameter of the oil return pipe 1 .
[0023] According to the above structure, the outer diameter of the insert tube 32 is equal to the inner diameter of the butt tube 21 , thereby improving the sealing performance between the insert tube 32 and the butt tube 21 .
[0024] like Figure 2-4 As shown, the structure of the first flange 23 is the same as that of the second flange 36. One side of the first flange 23 is a slope with an inclination angle of 30°-45°. The bottom of one side of the first flange 23 is an arc-shaped structure. There is a groove for welding between the first flange 23 and the second flange 36.
[0025] According to the above structure, a groove for welding is formed between the first flange 23 and the second flange 36 after docking. The first flange 23 and the second flange 36 not only play a role of thickening, but also play a role of guiding, which facilitates welding.
[0026] like Figure 2-4 As shown, the side wall of the insert tube 32 is symmetrically provided with through grooves, an elastic sheet 34 is fixedly connected inside the through groove, a protrusion 35 is fixedly connected to one end of the elastic sheet 34, and the inner wall of the butt tube 21 is symmetrically provided with grooves 22, and two protrusions 35 are respectively engaged and connected inside the two grooves 22.
[0027] According to the above structure, during docking, the protrusion 35 is recessed into the interior of the insert tube 32. When the protrusion 35 slides to the groove 22, the protrusion 35 is bounced up by the elastic sheet 34 and stuck in the interior of the groove 22, thereby avoiding relative sliding between the insert tube 32 and the docking tube 21. During welding, there is no need to perform spot welding to fix the parts, thereby preventing spot welding from welding through the parts.
[0028] The working principle of the utility model is as follows: during production, the insert sleeve 32 is first inserted into the interior of the butt pipe 21, the connecting assembly 3 is butt-jointed to one end of the oil return pipe 1, and then the butt assembly 2 and the connecting assembly 3 are welded together. After the butt assembly 2 and the connecting assembly 3 are butt-jointed, the second flange 36 and the first flange 23 are spliced together, and welding is performed between the first flange 23 and the second flange 36. During butt-jointing, the protrusion 35 is recessed toward the interior of the insert sleeve 32, and when the protrusion 35 slides to the groove 22, the protrusion 35 is bounced up by the elastic sheet 34 and stuck in the interior of the groove 22, thereby avoiding relative sliding between the insert sleeve 32 and the butt pipe 21. During welding, there is no need to perform spot welding to fix it, thereby preventing spot welding from penetrating the components. The outer diameter of the insert sleeve 32 is equal to the inner diameter of the butt pipe 21, thereby improving the sealing performance between the insert sleeve 32 and the butt pipe 21. After butt-jointing, a groove for welding is formed between the first flange 23 and the second flange 36, and the first flange 23 and the second flange 36 not only play a role of thickening, but also play a role of guiding, thereby facilitating welding.
[0029] The above is only a preferred embodiment of the present invention. It should be noted that, for ordinary technicians in the technical field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the field unless otherwise specified and limited.
