摘　　要：从满足自动换刀装置动作可靠性要求出发,对其换刀过程进行分析。在此基础上,建立了传动系统精度模型,分析了其传动系统磨损过程中的精度衰减情况。从而提出了一种基于精度衰减分析的动作可靠性设计方法。结合某链式刀库及自动换刀装置,应用所提出的动作可靠性设计方法进行了仿真计算及分析,结果表明该方法符合换刀装置动作可靠性设计要求。To meet the action reliability requirements of automatic tool changer （ATC） its process of changing tool is analyzed. Based on this analysis, the precision model of its transmission system is built, which analyses the precision attenuation of transmission system during the wear process. Therefore, an action reliability design method of ATC is proposed. Combined with some type of ATC, this paper car- ries out stimulation calculation by using the proposed action reliability design method. The results show that the approach is consistent with tool changer operating reliability design requirements.
