According to the outboard tube positioning and scribing method, the laser generator in the center of the fixed turntable determines the center position of the outboard tube, and the position of the edge laser generator is adjusted to simulate the outer diameter of the outboard tube. The position of the center of the outboard pipe on the outer plate is found out according to the coordinate values, a cross curve is drawn, a three-foot center chuck of the tool is clamped on a flange of a connecting pipe in the outboard pipe, at the moment, three points are projected on the curved outer plate, and the center point is adjusted to coincide with the center of the previous cross curve by adjusting the inner pipe and the support. The positions of the laser generators on the two sides are adjusted in the clamping grooves, so that the distance between the laser generators is equal to the outer diameter of the outboard pipe, then the wind belt connector is connected to the pneumatic motor, the fixed rotating disc rotates at a high speed, finally, the laser generators map the intersecting line of the outboard pipe on the curved shell plate, and tapping operation can be conducted on site according to lineation. According to the method, one-time development can be achieved, real-time adjustment is not needed, the outboard pipe installation period is shortened, the outboard pipe trepanning quality is improved, and the pre-welding inspection pass rate is increased.
一种舷外管定位划线方法,固定式转盘中心的激光发生器确定舷外管中心位置,调整边缘激光发生器的位置来模拟舷外管外径。根据坐标值找出舷外管中心在外板上的位置并画出十字线,将工装的三脚中心卡盘卡在舷外管内部连接管子的法兰上,卡紧,这时在曲型外板上投映出三个点,通过调整内部管子、支架将中心点调整至与之前的十字线中心重合。在卡槽里调整两侧激光发生器位置,使其间距与舷外管外径相等,随后将风带接头接入气动马达上,使固定式转盘高速旋转,最终激光发生器在曲型外板上映射出舷外管的相贯线,现场即可根据划线进行开孔作业。本发明可一次显影,无需时时调整,缩短了舷外管安装工期,提升了舷外管开孔质量,提高了焊前报验通过率。
