Do you know the design of combined tooling and fixtures in the manufacturing and processing of aeroengine compressor rotor impeller and stator impeller, the main characteristics and process requirements of impeller processing? If you don't know, let's explore the relevant information of impeller processing in aviation equipment together with the editor below!

Analysis of main features and processing technology requirements of rotor impeller and stator impeller:

The rotor impeller and stator impeller of the compressor are mostly staged, and the front and back are used for the turbine engine. They consist of blades and blisks and are an important part of a turbine engine. The materials are mostly aviation aluminum alloy and aviation titanium alloy. The working principle is the same as the airflow generated by the rotation of the blades of electric fans and propellers, which pushes the air into the cylinder and compresses it to generate high-pressure gas. In order to generate high-pressure air, multi-stage impellers are installed in the compressor, that is, different rotor impellers and stator impellers. The rotor impeller rotates to generate airflow that rotates with the rotor, and then the air is rectified by the stator impeller to generate high-pressure gas for the normal compression of the air.

The precision and process requirements of the compressor rotor impeller and stator impeller are very high. In production machining, there are complex turning and milling processes. The rough material is rough-machined with the outer circle turning tool, end face turning tool, end face R knife and inner hole knife by multi-tool CNC lathe respectively. , and then semi-finishing according to process requirements. After semi-finishing, the four-axis or five-axis CNC milling machine is used for rough machining of the blade, and then returned to the CNC lathe for finishing machining such as end face, outer circle, end face line, and inner hole. In order to ensure the quality of the rotor impeller and stator impeller, there are strict processing requirements in the middle.

In aviation equipment, impeller machining plays an important role. The improved impeller fixture not only meets the clamping requirements of the workpiece, but also simplifies the manufacturing process of the fixture and the method of replacing the tire core, so that the milling of the rotor impeller and the stator impeller can be quickly switched under simple operations, greatly reducing waste products The efficiency is reduced, the cumbersome steps of disassembling and correcting the fixture are reduced, and the method of clamping the workpiece is improved, which is simple and convenient, saves time and greatly improves production efficiency.
