Assessment Method of Machining Error of Globoidal Cam Based on Equidistant Model

  • 摘要: 弧面凸轮的廓面为空间不可展曲面,难以找到一种准确度高的快速测量方法.通过三坐标测量机搭配转台组成测量装置,对弧面凸轮等距模型的特征线进行测量,提出一种基于等距模型的弧面凸轮测量方法.首先,分析了等距模型的测量原理,避免了半径补偿;其次,提出了特征线的测量方法,评定等距模型的线轮廓度误差,讨论其对凸轮分度箱及换刀机械手的影响;最后,通过实验验证了测量方法的可行性,并提出了本测量方法的改进意见,可更好地实现弧面凸轮机构设计、加工、测量一体化.
    Abstract: Because of the complicacy of working profile of a globoidal cam,there is not a fast measurement method with high accuracy. A method of measuring the characteristic line on the equidistant model of the globoidal cam based on the three-coordinate measuring machine(CMM) and the turntable system is proposed. The measuring theory of the equidistant model without radius compensation is first analyzed. The line profile error of equidistant model is then calculated and the influence on cam gearbox and automatic tool changer(ATC) is discussed. Test results show that cam measurements method is feasible,providing a foundation for integration of globoidal cam's design,manufacture and measure.
