Description

法兰盘象限划规Flange Quadrant Planning

技术领域technical field

本实用新型属于划线装置领域,尤其是涉及一种法兰盘象限划规。The utility model belongs to the field of marking devices, in particular to a flange quadrant planning.

背景技术Background technique

在火箭装配过程中,燃料储箱与燃料输送管的连接通常依靠双法兰接头管连接,双法兰接头管的两端分别设置为小法兰盘和大法兰盘,小法兰盘上设置有一圈等间距的圆孔,小法兰盘需要套接入燃料输送管内且二者密封连接,大法兰盘则需要抵设于燃料储箱的燃料出口处且二者焊接。During the rocket assembly process, the connection between the fuel storage tank and the fuel delivery pipe is usually connected by a double-flange joint pipe. The two ends of the double-flange joint pipe are respectively set as a small flange and a large flange. There is a circle of equally spaced round holes, the small flange needs to be inserted into the fuel delivery pipe and the two are sealed, and the large flange needs to be placed on the fuel outlet of the fuel storage tank and the two are welded.

为了满足装配过程中的精度要求,圆形燃料出口的边缘预设有四条定位线,四条定位线将燃料口分划为四个象限,而装配过程中,要求四条定位线满足与小法兰盘上的圆孔的对应位置关系,即四条定位线所确定的象限需与小法兰盘上任意两个圆孔为基准圆孔所确定的象限对齐。In order to meet the accuracy requirements in the assembly process, four positioning lines are preset on the edge of the circular fuel outlet, and the four positioning lines divide the fuel port into four quadrants. During the assembly process, the four positioning lines are required to meet the requirements of the small flange. The corresponding positional relationship of the circular holes on the flange, that is, the quadrants determined by the four positioning lines must be aligned with the quadrants determined by any two circular holes on the small flange as the reference circular holes.

但是,由于小法兰盘与燃料出口不直接相连,二者不在同一平面上,四条定位线无法直接与小法兰盘上的圆孔确定位置关系,而燃料出口与大法兰盘直接相连,因此,需要在大法兰盘上划线来实现对齐,大法兰盘上所划的线必须与所选的两个圆孔在小法兰盘面上确定的象限的坐标轴上下对齐。However, since the small flange is not directly connected to the fuel outlet, the two are not on the same plane, the four positioning lines cannot directly determine the positional relationship with the round hole on the small flange, and the fuel outlet is directly connected to the large flange, so , it is necessary to draw a line on the large flange to achieve alignment. The line drawn on the large flange must be aligned up and down with the coordinate axes of the quadrants determined by the two selected circular holes on the surface of the small flange.
