摘要: 为实现对复合材料预制体的单边缝合,提高生产效率和产品质量一致性,基于单边双针双线缝合工艺,设计一种单边双针双线缝合头。该缝合头能够在复合材料预制体的一侧实现变角度缝合,增大缝合预制体厚度,提高预制体的抗切应力;它采用双电机驱动,具有摆动插刺机构以及同步传动机构等相关结构设计。在Pro/E中对缝合头进行总体设计与装配,并在Workbench中对缝合针进行强度校核。最后,对单边双针双线缝合头进行装配。

Abstract: To achieve single-sided stitching on composite material preforms, improve production efficiency, and ensure consistent product quality, a single-sided double-needle double-thread sewing head is designed based on the single-sided double-needle double-thread stitching process. Firstly, it can achieve variable-angle stitching on one side of the composite material preform, increasing the thickness of the stitched preform and enhancing its shear stress resistance. Secondly, the sewing head adopts a dual-motor drive and incorporates related structural designs such as the swinging stabbing mechanism and synchronous transmission mechanism. The overall design and assembly of the sewing head are carried out in Pro/E, and the strength verification of the suture needle is performed using Workbench software. Finally, assemble the single-sided double-needle double-thread sewing head.

Key words: single-sided double-needle double-thread stitching process, single-sided double-needle double-thread sewing head, swinging stabbing mechanism, strength check, composites
