摘　　要：多轴向经编机"移动复合针"中槽针的运动由上下运动和前后运动复合而成,针对这一特点,结合编织的实际需要,对槽针运动机构进行研究,探索相应设计方法。采用Watt型平面六连杆机构实现上下运动的一次近似停歇,利用另一组四连杆机构平面上的连杆点产生的近似直线轨迹实现槽针的上下直线运动,整体为平面十连杆机构;采用一次近似停歇六连杆机构与另一组四杆机构串联构成的八杆机构,使产生近似直线轨迹的四杆机构整体摆动,实现前后运动。根据停歇时间、动程大小等要求采用图解法对上下运动和前后运动机构进行尺度综合。最后通过实例分别生成了上下运动、前后运动的轨迹、变化规律,以及两种运动复合后的运动轨迹。The open-stem slide needle motion of ＂Walking Needle＂ in the multi-axial warp knitting machines is compounded of the vertical and the horizontal motion. Based on this situation, the paper studied the open-stem slide needle motion mechanism and explored the corresponding design method according to the actual demand. It used a watt six-bar linkage to realize an approximate dwell, the link point of another four-bar linkage which generates approximate linear curve to realize the vertical motion of the open-stem slide needle, and then the whole mechanism of the vertical motion is a ten-bar linkage. It used approximate dwell of a six-bar linkage and another set of four-bar linkage to connect with each other to form a eight-bar linkage, making the four-bar linkage which generates approximate linear curve oscillate wholly in order to realize the horizontal motion. It adopted the graphic method to realize the dimension determination of the vertical and the horizontal motion mechanism by the require- ments of the dwell time, the stroke and etc. It generated respectively the motion curve and the change law of the vertical motion and the horizontal motion, as well as the motion curve of the compound of two motions.
