在自动化生产过程中,根据生产工艺的需要,必须使回转工作台作间歇运动。即转动一个工位后,需停顿一段时间,以完成该工序的操作,然后再转一个工位。而在机器中起间歇作用的主要零件,在很多场合均采用转位凸轮。因为它结构简单、转位准确。但凸轮的设计计算工作量很大。如设计一个 In the automated production process, according to the needs of the production process, the rotary table must be intermittent movement. That is, after rotating a station, it needs to pause for a while to finish the operation of the process, and then turn to a station again. The main parts that play a role in the machine intermittently, in many occasions are used indexing cam. Because of its simple structure, indexing is accurate. However, the design and calculation of the cam workload. Such as designing one
