中文摘要:
      目的 针对凸轮机构的运动特点和规律,提出一种基于 ARM7 和伺服电机的电子凸轮系统,用于代替机械凸轮实现凸轮运动。 方法 重点论述凸轮曲线的设计方法和电子凸轮的实现方法,采用三次多项式插值方法建立凸轮运动的数学模型,得到平滑的速度和加速度曲线。 基于定步法原理得到电机的控制表格,且使用查表法实现伺服电机的升降频控制,同时给出软硬件设计方法。 结果 该系统输出的凸轮运动具有可调、定位精确、无冲击等特点。 结论 该系统成功地应用于包装机械中,提高了包装机械的包装速度、精度、输出柔性和智能化程度,具有明显的应用效果。
英文摘要:
      Objective According to the characteristics and laws of cam, this paper put forward an electronic cam system based on ARM7 and servo motor in order to realize cam motion instead of mechanical cam. Methods This article mainly discussed the methods of cam profile synthesis and implementation of electronic cam. The cam爷 s mathematical model was established by cubic polynomial interpolation. The control table was obtained according to the principle of given-step method and the frequency raising-lowering control of the servo motor was realized by the method of table lookup, meanwhile a method of software and hardware design was provided. Results The motion based on this system was adjustable, accurate in positioning and non-impact. Conclusion Applying this system to packaging machinery could improve features such as package speed, package precision, output-flexibility and intelligent degree. It has been proven to provide benefits to the packaging machinery.
