摘要

随着高精密磨削技术的不断发展,对数控机床的可靠性要求越来越高,磨削载荷谱是构建磨床主轴可靠性试验平台的关键科学依据。本文以轴承套圈内圆磨床主轴载荷为例,根据机床主轴实际磨削过程,利用测试机床主轴磨削功率方法对磨削加工载荷进行长期试验测试、记录和分析,研究了其载荷信号特征及处理方法,并给出了磨床主轴载荷谱的编制方法。最后,本文绘制了"空转-磨削-空转"与真实的现场载荷相一致程序载荷谱,为磨削主轴可靠性试验提供加载条件和理论依据,对提高磨床主轴可靠性设计有着重要意义。

Abstract

With high precision grinding technology development,the requirement for machine tool reliability is higher and higher.The load spectrum of grinding is key scientific basis of building the grinding machine spindle reliability experiment platform.Based on bearing ring machine tool grinding process,the load spectrum signal characteristic and processing method is studied through long time grinding spindle load measurement,recoding and analysis.Then,the compilation method is provided to get load spectrum.At last,the programmed load spectrum for "idle-grinding-idle"is drawn,which is consistent with real field load.It provide the loading condition and theory basis for grinding machine tool spindle reliability experiment,and also is very important to improve machine tool spindle design.
