摘要:

主轴系统是数控机床的重要组成部分,为金属切削提供切削力矩和切削速度,其性能直接影响机床的加工精度和效率。文中对数控机床主轴系统主要部件进行故障机理分析,基于故障机理设计了一种监测方案,通过外置传感器采集主轴系统主要部件的运行信息,并采用小波分析技术分析其运行信息,从而达到对主轴系统实时监测的目的。实验结果表明,文中案可以有效地检测出主轴系统主要部件的故障情况。

Abstract:

The spindle system plays an important role in CNC Machine,providing cutting torque and the cutting speed for metal removal.Its performance has a direct influence on the processing precision and efficiency of the machine.This paper analyzes the failure mechanism of the major component of CNC machine spindle system,and a series of monitoring schemes are designed on basis of the failure mechanism by means of operating information of the key component from the collecting Spindle System of the outer sensor.The wavelet is also adopted to analyze its operating information so as to monitor literally for the spindle system.The results indicate that this scheme can detects the fault condition of the key component of machine spindle system effectively.

Key words: spindle system;spindle;bearing;gear;spindle motor;wavelet analysis;fault monitoring
