Description

A processing device for turbocharger turbine shaft

technical field

The invention relates to the technical field of milling and grinding of shaft parts, in particular to a processing device for a turbine shaft of a turbocharger.

Background technique

A turbocharger is actually an air compressor that compresses air to increase intake air.

The turbocharger is mainly composed of two parts: a compressor and a turbine. Among them, the main function structure of the compressor is the impeller, and the main function structure of the turbine is the turbine, and the impeller and the turbine are fixedly connected by a shaft, that is, the turbine shaft, the turbine The shaft mainly plays the role of transmitting torque.

During assembly, the turbine shaft runs through the middle casing of the entire supercharger. In order to ensure the sealing of the turbocharger and smooth rotation, several components including gaskets and ball bearings need to be installed on the turbo shaft. These parts are usually installed in the circumferential annular groove opened on the turbine shaft.

The turbine shaft blank obtained by forging needs to go through a multi-step finishing process including turning, milling and grinding to obtain a finished turbine shaft that meets the conditions of use. And there are many inconveniences in the grinding process, especially in the use of the existing devices for turbine shaft workshop production and processing, the following problems will inevitably occur:

1. The existing turbine shaft processing device mainly adopts the method of clamping one end of the turbine shaft when milling and grinding the turbine shaft. For long-axis parts such as the turbine shaft, a single Side clamping will lead to insufficient clamping, especially in the process of machining the turbine shaft, which needs to drive the turbine shaft to rotate around the axis, and insufficient clamping force will easily lead to the fall of the high-speed rotating turbine shaft on the one hand, posing a safety hazard. On the one hand, insufficient clamping will also cause the turbine shaft to vibrate and deviate during the machining process, resulting in machining errors and affecting the machining quality of the turbine shaft.

2. The milling and grinding of the existing turbine shaft are usually carried out on different devices, and the milling and grinding of the turbine shaft cannot be performed at the same time, and the processing efficiency is low; during the entire processing process, it is necessary to frequently The turbine shaft is disassembled and installed, and the installation datum is difficult to be accurate and uniform, which will lead to a gradual increase in the machining error due to the installation deviation in the process of multi-step processing, and it is difficult to eliminate; and the workpiece is frequently disassembled and installed It also reduces processing efficiency.

3. The processing position and processing depth of the annular groove on the turbine shaft are not fixed, and need to be adjusted according to the type of turbocharger it is applied to. However, the existing processing device, after the turbine shaft is clamped once, It is difficult to adjust the position and milling depth of the turbine shaft to be processed.

4. Due to the many parts and complex structure of the existing processing device, there are many inconveniences in the processing and installation of the turbine shaft, and the problem of difficult installation of the turbine shaft often occurs due to the interference of other mechanisms.

In summary, there are obviously inconveniences and defects in the actual use of the prior art, so it is necessary to improve it.
