The invention discloses a fixed method for locating a ship's mainframe accurately and firmly, and is a method for the installation of ship machinery in ship building or ship repair. Its features are: the host ship positioning, the host machine feet and host host seat while drilling reaming; processing according to the outer diameter of the bolt and thread after reaming size, the outer diameter of the bolt is larger than the diameter 0.005 ~ 0.015mm after reaming the bolt; frozen; bolts to remove after freezing. Immediately into the host machine and the host foot seat while reaming of Kong Zhong, and the bolt head threaded sleeve gasket with nuts will host machine feet and host seat lock. Because the invention utilizes the most common principle of thermal expansion and cold contraction, it is referenced to the installation of ship main engine, so that the outer diameter of the bolt can be larger than the outer diameter of its coordination, and it can smoothly install into the hole without displacement. The assembly method of the invention is not only simple, but also easy to operate, and can increase the service life by 2~3 times than that of the original method.
【技术实现步骤摘要】
一种定位准确锁紧牢固的船舶主机的固定方法本专利技术涉及造船或修船中船舶机械安装的方法,具体的说是一种定位准确锁紧牢固的船舶主机的固定方法。现有的船舶主机的安装是将主机定位后,用磁力座台钻在现场将主机机脚、垫块和主机座同时钻孔后铰孔,根据铰孔后尺寸加工铰配螺栓。传统的配合方式是过渡配合,安装时是用锤子将螺栓敲打进去的,其缺点是安装困难,定位的可靠性差。因此,在使用过程中会引起主机的位移,给正常行驶的船舶带来诸多的不便。为此,必须加以克服。为了克服现有技术的足,本专利技术的目的是要提供一种定位绝对准确且锁紧牢固的船舶主机的固定方法。本专利技术解决其技术问题所采用的技术方案是:一种定位准确锁紧牢固的船舶主机的固定方法,其特征是:1、船舶主机定位后,用磁力座台钻在现场将主机机脚、垫块和主机上的主机座同时钻孔,然后铰孔;2、螺栓的加工:根据铰孔后的尺寸进行螺栓外径及螺纹的加工,其中螺栓外径比主机机脚及主机座、垫块铰孔后的孔径大0.005~0.015mm;3、将螺栓实施冷冻,冷冻温度为零下4~20度,一般冷冻时间为4个小时;4、取出冷冻后的螺栓,马上放入主机机脚和主机座同时铰孔 ...
