Description

一种水下湿式焊接自适应激光工具
技术领域
本发明涉及一种焊接工具，特别涉及一种水下湿式焊接自适应激光工具。
背景技术
水下焊接技术，已经在海洋工程、船舶船坞、港口设施、江河工程及核电厂的建造和维修中得到广泛应用。虽然陆上焊接工艺有很多选择，如电弧焊、激光焊、电子束焊、摩擦焊、超声波焊等；但水下焊接工艺，却主要以电弧焊为主。对激光焊接工艺来说，限制其水下应用推广的主要原因是水介质对激光吸收能力强，导致入射到焊接金属上的能量很少。
因此，研发一种能够避免水下激光吸收影响焊接质量的装置势在必行。
发明内容
本发明要解决的技术问题是一种能够自适应水下焊缝位置的起伏波动，确保焊接质量的水下湿式焊接自适应激光工具。
为解决水下激光吸收影响焊接质量的问题，本发明的采用一种水下湿式焊接自适应激光工具，其特征在于：包括准直镜筒、反射镜筒、控制器、可伸缩聚焦镜筒、直线电机、距离探测器，所述反射镜筒具有一个激光入射接口和一个激光出射接口，且所述激光入射接口与激光出射接口相互垂直，所述准直镜筒与反射镜筒的激光入射接口连接，所述可伸缩聚焦镜筒与激光出射接口连接；所述可伸缩聚焦镜筒包括一个固定筒段和一个活动筒段，所述固定筒段同轴套装在活动筒段外，并在固定筒段与活动筒段之间安装有直线电机，所述距离探测器安装在固定筒段上远离活动筒段的一端外圆周面上，所述控制器安装在反射镜筒内，所述距离探测器的输出信号接入控制器的信号输入接口，控制器的信号输出接口连接直线电机。水下激光焊接时，镜筒底面到焊接面的距离十分关键，这个距离过长，起不到光程包覆的作用，水介质对激光能量的吸收会急剧上升。而由于水下待焊金属面的平面度较差，且激光焊接工具的运载机构在水下也难以保证控制精度，镜筒底面到焊接面的距离过短的话，又容易造成镜筒与焊接面的擦碰。而本发明中，采用直线电机驱动的可伸缩聚焦镜筒，利用距离探测器来控制可伸缩聚焦镜筒的伸缩，保证镜筒底面与焊接金属面的距离恒定。自适应水下焊缝位置的起伏波动，较小的距离能减弱水介质对激光能量的吸收，并能确保焊接质量。
此外，所述固定筒段与活动筒段之间设置有活动密封组件，确保在运动中的水密性。
附图说明
图1为本发明的结构示意图。
具体实施方式
包括准直镜筒1、反射镜筒2、控制器3、可伸缩聚焦镜筒4、直线电机5、距离探测器6，反射镜筒2具有一个激光入射接口和一个激光出射接口，且激光入射接口与激光出射接口相互垂直，准直镜筒1与反射镜筒2的激光入射接口连接，可伸缩聚焦镜筒4与激光出射接口连接；可伸缩聚焦镜筒4包括一个固定筒段和一个活动筒段，固定筒段同轴套装在活动筒段外，并在固定筒段与活动筒段之间安装有直线电机5，而距离探测器6安装在固定筒段上远离活动筒段的一端外圆周面上，控制器3安装在反射镜筒2内，距离探测器6的输出信号接入控制器的信号输入接口，控制器的信号输出接口连接直线电机5。
此外，固定筒段与活动筒段之间设置有活动密封组件，该活动密封组件为常规的水下活动密封组件，确保在运动中的水密性。
工作原理：将可伸缩聚焦镜筒的底面与焊接面的距离设计为≤3mm（该距离可以在控制器内设定）。在焊接金属面起伏波动，或运载机构控制精度不高时，可伸缩聚焦镜筒上的距离探测器能够实时检测镜筒底面到焊接面的实际距离，并将该距离值反馈给控制器。控制器通过PID控制算法，发出运动指令给直线电机。直线电机将驱动可伸缩聚焦镜筒带动聚焦镜上下运动，保证镜筒底面与焊接金属面的距离恒定。
