焊枪自动调整装置的结构设计与分析 摘要 本设计是在仔细研究了生产实际对焊枪自动调整功能的需要上，设计了一种经过直线模组构造完成焊枪摆动功能的摆动器，摆动器实现了在Y方向和Z方向的自由移动，在末端安装焊枪，焊接的状态下焊枪能够在焊缝外表左右上下摆动，摆动的幅度与摆动的频率可以调节，完成焊枪左右上下摆动的功能，在这个基础上实现了焊枪的自动调整，本文详细介绍了摆动器装置和焊枪的结构和功能。在自动化生产焊接的要求下，焊接专机需要装配送丝机构，在送丝盘上设计一个送丝架，实现自动送丝，焊丝类型及送丝速度决定焊缝的宽度，因为调整送丝速度来调整焊缝宽度有限，直线焊接很简单不能满足不同的焊接工件焊接工艺的需求。为了改善不同焊缝的表面，多道焊接不同焊层的焊接品质，让自动焊接设备能够适应各种工件的厚度及工艺生产要求，必须要设计一种焊枪自动调整装置。 关键词：焊枪摆动器自动调整装置自动化 Abstract This desig
