摘要

基于薄盘类零件具有较大径厚比，且不平衡量可以看作分布在一个平面内的特点，提出一种基于夹载工件前后机床主轴不平衡振动信号的变化而间接、在线测算薄盘类工件不平衡量的方法。基于附加不平衡振动检测系统、复合数控机床的主轴准停、刀具定位及去重控制等功能，提出薄盘工件不平衡量在线去重校正的理念。通过试验证实了工件不平衡量在线测算及校正的可行性。本研究可以在无动平衡机的条件下实现薄盘工件不平衡量的在线测算与去重校正，在节省工件平衡成本、提高工件平衡效率与加工精度等方面具有参考价值。

Abstract

Based on the fact that the unbalance vector of the thin-disk part with large diameter–thickness ratio can be regarded as distributed in one face

the measuring and calculating methods for the unbalancing vector of thindisc workpiece are proposed according to the vibration change of machine tool spindle before and after the workpiece is clamped. Based on the extra unbalance vibration measuring system

the functions of spindle exact stop

tool positioning and weight moving control of composite numerical control machine tools

the concept of online weight moving correction for the unbalance thin-disk workpieces is proposed. The feasibility of unbalance vector online measurement and correction for thin-disc workpiece is verified by experiments in the paper. The research can be used to online measure and correct of the unbalance thin-disk workpiece without dynamic balancing machine

and it has certain reference value in saving workpiece balance costs

improving workpiece balance efficiency and machining accuracy.
