气压式端子压着机结构设计 摘要 压着连接是端子连接器的连接或金属导体末尾与相似的金属器件连接的一种方式。端子压着机是完成聘丝与端子冷焊接的机械，端子压着机也属于进行线束加工的最后一道工序。 气压式端子压着机是将传统的手动压接钳替换下来进行的改造设计，实现自动化装配功能。主要可分为三个装置：聘丝夹持切断装置；聘丝送进压溃装置；端子传送抬起装置。聘丝送进压溃装置的作用主要是对聘丝位置进行锁定，并输送；聘丝夹持切断装置的作用主要是将聘丝送进压溃装置输送的聘丝进行切割；端子传送抬起装置的作用主要是将端子传送到定点位置后抬起，使聘丝压入，整个工作就完成了。 本次设计主要采用理论研究、计算、机械图绘制和计算机辅助设计的方法。通过查阅相关文献，了解端子压着机的工作原理、动作过程、各部件所起的作用，特别是对输送端子与定位装置的机械结构和工作原理进行研究，提出设计思路和方案；进行相关的理论计算，确定送输端子装置和定位装置主要零部件；采用CATIA表达出各装置三维模型。完成零件和部件的设计，并且用AutoCAD表达出各个机械结构图样。 本次机构整体设计不占用多余的空间，整体符合紧凑的实际理念。设计的气压式端子压着机解决了人工手动、产量和产品质量等问题，大大提高了工作效率，基本实现了自动化。 关键词：端子；自动化；压着连接；结构设计 ABSTRACT The crimp co
