摘　　要：为了开发剑杆织机的引纬运动装置，对织机的引纬类型进行了研究。针对共轭凸轮引纬机构，分析了引纬机构中剑头的运动规律，得到剑头相对于共轭凸轮运动要求为具有两次停歇的往复摆动；根据摆角变化特点，建立了平面四连杆机构的图解法模型，给出了设计平面四连杆机构的方法和步骤；再结合剑杆加速度运动规律，通过MATLAB编程软件求解得到共轭凸轮工作轮廓线；最终，得到引纬机构的所有尺度。In order to develop the weft insertion motion device of rapier loom, the type of the weft insertion is researched. As for the conjugate cam weft insertion mechanism, the motion law of the sword head in the weft insertion device is analyzed, and the motion law of the sword head required to be the reciprocating swing with two stops relative to the conjugate cam is obtained. According to the characteristics of swing angle, the diagrammatized method model of planar four-bar linkage is established. In detail, the methods and procedures for designing planar four-bar mechanism are provided. The working contour curve of conjugate cam is obtained by MATLAB programming in combining with the acceleration motion law of rapier. Finally, all dimensions for the weft insertion device are obtained.
