三维编织夹头机构的结构设计

针对三维编织过程中，以集体绑束进行固定纱线端部的常规方式存在的不足，提出一种用于固定纱线端部的夹 头机构。该机构采用多个简单模块组合的形式，为每根纱线设置了挂钩和专用通道，使用导柱、导套结构为运动提供保 证。使用结果表明该机构能够保证纱线在行、列方向是等间距的，适用于多种不同形状预制件纱线的固定，应用方便、可 靠。该机构能实现纱线的有序固定，减小过渡长度且适用范围广、扩展能力强。

Structure Design of Chuck Institution on Three-Dimensional Knitting

ln the process of three-dimensional knitting, the conventional way of fixed yarn ends with a collective yarn tie has shortcomings. A kind of chuck institution for fasten ends of yarn was put forward. This institution adopted the form of many simple module combination. and set the hook and dedicated channel for each yarn. By using the guide pin and guiding sleeve structure it provided guarantee for movement. The use results show that this institution can ensure the yarn with even space in direction of the line and column. and it is applicable to fix yarn of a variety of different shape fabricated part. And the institution is convenient and reliable. It achieves orderly fixed yarn and reduces the transition length. It has wide range of application and strong ability to extension.
