摘要
利用摇杆的预定急回运动设计了曲柄摇杆滑块机构。采用计算机软件生成凸轮模型,并对凸轮机构进行运动分析,得出摆动从动件凸轮机构在运动过程中的速度与加速度曲线,通过正确选择凸轮从动件运动规律,来减小推药过程中推药板对药组的冲击力,实现柔性推送药卷的目的。整个机构以2 s为一个周期,停歇1 s,推送的进程和回程在1 s内完成。
The crank rocker sliding-block is designed based on predetermined quick return motion of the rocker. The cam model and motion analysis are formatted by computer software to obtain the velocity and acceleration curve in the mo- tion of oscillating follower cam. The impact force of pushing slab can be decreased during motion by the correct selection of cam motion law. Of the 2 s cycle of whole device, it is stopped for 1 s, and the go and return process of pushing complete in the other 1 s.
