Oil return pipe joint and installation tool thereof

Abstract

The invention relates to the technical field of a turbocharged engine, and discloses an oil return pipe joint and an installation tool thereof. The oil return pipe joint comprises: a first pipe body (1), wherein a first end of the first pipe body is connected to an oil return hole of an engine cylinder, an end surface of a second end of the first pipe body includes a first plane (11) and a secondplane (12) for receiving the assembly force, the first plane is perpendicular to a central line of the first pipe body, and the second plane and the central line of the first pipe body form an obtuseangle from the second end to the first end; and a second pipe body (2), wherein the second pipe body is connected to an oil return pipe of a supercharger, and the second tube body and the first tube body are connected in the second plane. According to the oil return pipe joint of the present invention, the first pipe body has the first plane and the second plane, the first plane and the second plane can simultaneously bear the thrust of the installation tool of the present invention, and the force is uniform. The installation reliability and sealing performance of the oil return pipe joint isimproved, and the installation speed is accelerated.

Description

technical field [0001] The invention relates to the technical field of turbocharged engines, in particular to an oil return pipe joint and an installation tool for installing the oil return pipe joint. Background technique [0002] A turbocharged engine refers to an engine equipped with a turbocharger. When the engine speed increases, the turbocharger can use the kinetic energy of the exhaust gas to increase the turbine speed synchronously, and the coaxial compressor impeller rotates to greatly increase the pressure and density of the intake air, so that the engine can burn more fully. , to increase the output power. However, due to the high temperature of the exhaust gas and the high-speed rotation of the impeller will cause the temperature rise and serious wear of the housing and transmission parts, a continuous flow of oil is needed to cool, clean and ensure transmission efficiency. [0003] Considering the assembly size and the interference of parts, etc., the oil retu...

AI Technical Summary

Problems solved by technology

However, due to the high temperature of the exhaust gas and the high-speed rotation of the impeller, it will cause the temperature rise and serious wear of the housing and transmission parts, so a steady stream of oil is needed to cool, clean and ensure transmission efficiency

[0003] Considering the assembly size and the interference of parts, etc., the oil return pipe joint of the supercharger currently used has a special shape and small size, so it is difficult for the operator to find the force application point during the installation process, and the uneven force will cause the sealing ring to cut , causing a more serious problem of engine oil leakage

At the same time, due to the particularity of the structural shape, high-frequency installation will cause severe soreness in the fingers of workers, affecting CT time (Cycle Time, the average time required to complete a product), and lower production efficiency
