The invention discloses a method for opening outboard tube mounting holes. The outboard pipe mounting hole opening method comprises the following steps that S1, a bolt through hole is designated; s2, mounting a positioning sleeve; s3, installing a laser pen; s4, marking a projection point of the circle center of the specified bolt through hole; s5, marking the circle center of the trepanning line; s6, marking out a hole opening line; and S7, trepanning. The device solves the problems that in the prior art, operation is relatively troublesome, the working efficiency is low, the precision of obtained tapping lines is poor, and outboard pipe installation is not facilitated.
本发明公开了一种舷外管安装孔的开孔方法。该舷外管安装孔的开孔方法包括如下步骤:S1、指定螺栓过孔;S2、安装定位套;S3、安装激光笔;S4、标记指定螺栓过孔圆心的投影点;S5、标记开孔线的圆心;S6、划出开孔线;S7、开孔。本发明解决了现有技术操作相对麻烦,工作效率低,且得到的开孔线精准度差,不利于舷外管安装的问题。
