The invention relates to the technical field of ships, in particular to an axis penetration technology after installation of a large ship building main engine, which comprises the following steps of: 1, confirming axis distance and aperture information; 2, a laser generator is installed on the target core with the axis penetrating through the datum point of the bow, laser is emitted, and a light spot is adjusted to ensure that the center point of the light spot corresponds to the axis point of the stern shaft tube; step 3, installing a target core for penetration; 4, after the target core at the transparent position behind the host is mounted in place, the transparent target core is dismounted, and the laser transmitter is dismounted and mounted on the transparent jig of the stern shaft tube; and step 5, adjusting the center position of the laser spot on the target core behind the laser emitter and the host at the position of the stern shaft tube according to the method in the step 2, ensuring that the center of the laser spot is on the center of the small hole of the axis of the target core for penetration, and sequentially mounting the removed target cores backwards. It is guaranteed that laser spots can be seen from the round hole in the axis position of the target core at the bow datum point. According to the invention, the precision of axle center penetration data measurement is effectively improved.

    本申请涉及船舶技术领域,一种大型船舶建造主机安装后轴心见透工艺,步骤一:确认轴心距离和孔径信息;步骤二:在轴心见透艏部基准点位置的靶芯上安装激光发生器,发射激光,调整光斑保证光斑中心点对应艉轴管位置的轴心点;步骤三:安装见透用靶芯;步骤四:主机后面见透位置的靶芯安装到位后,拆除见透用靶芯,激光发射器拆除安装到艉轴管的见透治具上;步骤五:再按照步骤二的方法调整好艉轴管位置的激光发射器及主机后面见透靶芯上激光光斑的中心位置,保证激光光斑中心在见透用靶芯的轴心小孔中心上,向后依次安装好拆除掉的靶芯,保证在艏部基准点处靶芯上的轴心位置圆孔能看到激光光点。本申请有效提高轴心见透数据计测的精度。
