本申请还提供了焊枪浮动端面凸轮装置6的设计方法，步骤如下：首先从工件14上确定焊缝处相贯线的特征，即上下修正量及轨迹，以对正面为起点，确定每转20度上下修正量，按此数据设计浮动端面凸轮，凸轮的安装与工件上的焊缝轨迹的方向一致，整个焊枪机构是挂在焊枪浮动端面凸轮装置6的高低面上的，焊枪机构用竖直安装的焊枪浮动导轨9为上下导向，并随空心中轴7旋转，凸轮固定时，焊枪机构的自重导致焊枪机构上下运动，焊枪16对正焊缝时焊枪头部的旋转与上下运动轨迹与焊缝的相贯线相近，达到自动修正的目的。
工作原理
工件14放在工件托架19的规定位置，工件小嘴15放在工件桶体的对应位置，并在工件托架19上的定位钉上定位，机器的压紧活络头12下部装有与工件小嘴15定位尺寸吻合的定位压紧件13，升降机箱在升降气缸24的作用下向下运动，完成机构对工件的定位。工件14与工件小嘴15呈相贯状态，其相交部分就是相贯线，机器开始焊接时，空心中轴7开始旋转，空心中轴7的旋转带动了焊接机构的旋转，焊枪浮动端面凸轮装置6的端面凸轮固定，焊枪浮动吊杆8上部的轴承即在端面凸轮上转动，因机构自重的原因，整个焊枪机构即随着浮动端面的上下高度变东南上下运 动，焊枪的运动轨迹即按工件的相贯线作相对吻合的运动，实现自动高度修正的焊接运动。
