摘要：为解决当前Z-pin植人设备植人效率低、Z-pin易折断或打滑等问题,并推动Z-pin增强技术高效地应用于民用和国防事业，开发了基于组合凸轮的高效高精度Z-pin预植人机。首先，根据航空矩形类复合材料层合构件的预植人工艺技术要求，分析了预植人机的功能需求。其次，提出了先“剪切”后“植人”组合凸轮式预植入机的机构运动方案。采用解析法设计了预植入机的凸轮机构，计算了凸轮机构的理论轮廓曲线。然后，构建了含有间隙凸轮机构的弹性动力学模型，优化了组合凸轮的转速，进行了组合凸轮的虚拟样机运动仿真。最后，设计制造了实验样机,通过植人实验验证了组合凸轮设计的正确性和合理性,并根据实验中出现的问题优化了植人运动方案。实验结果表明，该方案使Z-pin植入效率得到大幅提高，以植入间距3mmX3mm为例,其效率能够达到5080mm/min，植人成功率控制在99%以上，植人间距、植入深度和纤维长度等参数的精度均控制在士0.01mm以内。预植入机操作方便，人机界面友好，长时间工作平稳，无Z-pin折断等问题出现，能满足当前对Z-pin植人设备植人效率、植入精度的要求。

Abstract: In this study , a new high-efficiency and high-precision Z-pin pre-insertion based on a combination cam was developed to solve the problems , such as low efficiency , easy breaking , and slipping of Z-pin insertion . One of the aims is also to promote the application of the Z-pin composite technology in both military and civil fields . First, the functional requirements of the pre-insertion machine were analyzed according to the pre-insertion technology requirements of laminated composite members of the rectangle-type aviation. Second, the mechanism motion scheme of the“shear after implant” combined cam-type program was proposed for the pre-insertion machine. The cam mechanism of the pre-insertion machine was designed using the analytical method , and the theoretical
