Structure Design And Realization Of The Twin Face Lathe Spindle

In recent decades, the aviation industry gets a rapid development in China, but compared to other countries, there still exits a considerable gap in the aspect of high-quality manufacturing of aircraft. There are many thin-walled parts in aero-engine. Due to the poor working condition, the high quality of this kind of parts should be guarantee. It is of great significant to reduce the deformation of the thin-walled parts and achieve the high quality process of aero-engine.This paper put forward the twin-face turning process to solve the machining deformation of the compressor disk. This process can suppress the machining deformation of the compressor disk and get a high component due to the normal cutting force of the workpiece balanced each other. In this paper, the spindle of the twin-face lathe has been designed. The main research of this paper including:(1) Analysis the characteristic and machining difficulties of the compressor disk, determine the design target of the spindle.(2) Design the spindle of the lathe in detail and check the strength of the main components.Spindle design includes the transmission, headstock, lubrication systems, jigs and fixtures.Firstly, the 3D model and assembly model of the spindle components has been created by using Solidworks. It can avoid the interference occurred in the spindle design. After that, the strength of main component has been checked by using Ansys Workbench to ensure the component failure do not occur during life time.(3) Finished the 2D design of the spindle by using AutoCAD. After the machine of the parts,the assembly of the spindle has been completed. Therefore, the accuracy of the spindle can be detected. The results show the accuracy meet the design target of the spindle. Finally, the twin-face lathe should be trial operation. During that time, the spindle can work normally.(4) Put forward the four point method to separate the spindle error. Then, use Matlab to do some simulation about the algorithm. The simulation results show the separation accuracy of the algorithm can meet the requirement.
