背景技术Background technique
变焦凸轮是变焦光学系统用于实现光学变焦的关键零件,变焦凸轮的工作原理是利用该零件本身的曲线轮廓带动与之连接的从动零件做往复移动,即通过该零件的回转运动转化成从动零件的直线运动。所以该零件加工完成后的圆柱体直线度、圆柱体圆度、螺旋槽曲线的加工精度和多线螺旋槽在圆柱体上的均分度等直接影响着光学系统的成像质量。The zoom cam is the key part of the zoom optical system to achieve optical zoom. The working principle of the zoom cam is to use the curve profile of the part itself to drive the driven part connected to it to reciprocate, that is, to convert the rotary motion of the part into Linear motion of moving parts. Therefore, the straightness of the cylinder, the roundness of the cylinder, the machining accuracy of the spiral groove curve and the even division of the multi-line spiral groove on the cylinder directly affect the imaging quality of the optical system after the part is processed.
传统的检测方法只能依靠少量配套有高精度旋转机构的三坐标测量机进行近似测量,三坐标测量机检测的结果因测量探头的形状、接触点位置、螺旋槽曲率、接触角度和接触深度、曲线拐点圆滑度等多方面因素的影响,导致检测结果不准确且不稳定,存在不同程度的误判,同时整个过程繁琐、耗时、检测不确定性大、检测成本高。Traditional detection methods can only rely on a small number of three-coordinate measuring machines equipped with high-precision rotating mechanisms for approximate measurement. Influenced by many factors such as the smoothness of the inflection point of the curve, the detection results are inaccurate and unstable, and there are different degrees of misjudgment. At the same time, the whole process is cumbersome, time-consuming, with high detection uncertainty and high detection cost.
