Description

Technical Field

[0001] The invention relates to the technical field of combined processing of shaft parts, and in particular to an integrated processing device for a turbocharger rotor shaft. Background Art

[0002] A turbocharger is actually an air compressor that increases the intake volume by compressing air. The turbocharger uses the inertial force of the exhaust gas discharged by the engine to drive the turbine in the turbine chamber, which in turn drives the coaxial impeller, which presses the air sent from the air filter pipe to increase the pressure and enter the cylinder.

[0003] Structurally, a turbocharger includes a turbine housing, a compressor housing, an intermediate housing, a turbine, a pump wheel, a floating bearing, an exhaust bypass valve, and an actuator. The turbine and the pump wheel are assembled on the same shaft and are respectively installed in the turbine housing and the compressor housing through two floating bearings. The intermediate housing has oil passages for lubricating and cooling the bearings, as well as sealing devices to prevent oil from leaking into the compressor or turbine.

[0004] Among them, the shaft used to connect the turbine and the pump wheel is called the rotor shaft. Its main function is to support the transmission parts and transmit torque between the turbine and the pump wheel. Since the turbocharger itself is a complex machine with a certain precision, high assembly accuracy is required for each component; furthermore, the rotor shaft must bear loads and ensure a certain rotation accuracy during work. Therefore, the rotor shaft blank obtained by forging usually needs to undergo multiple complex processing steps to improve its use accuracy.

[0005] Specifically, after normalizing, the rotor shaft blank obtained by forging and casting usually needs to undergo a series of processes such as milling the end face, drilling the center hole, rough turning, fine turning, heat treatment and surface grinding. In the existing technology, the above-mentioned diversified processing is often carried out on multiple different equipment, that is, there is a lack of a multifunctional processing equipment to synchronously realize the combined processing of the rotor shaft, so that the following problems caused by the existing step-by-step processing method cannot be solved: 1. The function is single, and it is difficult to realize the diversified processing of the same rotor shaft and the adaptive processing of different rotor shafts.

[0006] 2. Failure to unify the clamping datum can easily cause processing errors and reduce the overall processing accuracy.

[0007] 3. The processing continuity is poor, and it is impossible to realize the automatic switching of the rotor shaft in different processing procedures.
