阿基米德螺旋线凸轮是机械结构中常用的一种等速凸轮,通常在万能铣床上利用分度头进行铣削加工。该加工方法平衡机床负荷较为不便,且需搭配传动齿轮。为便于加工,笔者设计了一种用于铣削阿基米德螺旋线凸轮的工具,使用结果证明,完全能满足凸轮加工要求。该工具的结构如图1所示 Archimedes spiral cam is a commonly used mechanical structure of a constant speed cam, usually universal milling machine using indexing head for milling. The processing method to balance the machine load is more inconvenient, and with the transmission gear. In order to facilitate the processing, I designed a tool for milling Archimedes spiral cam, the results show that fully meet the cam processing requirements. The structure of the tool shown in Figure 1
