航天产品的制品再利用管理方法初探

Research on the Management Methods for Product Reuse of Aerospace Products

摘要: 针对蒙皮制品上装配孔与新桁条装配孔不协调问题，提出两种方案，对于方案一通过理论计算、实际测量得出桁条装配孔的理论位置，并对其中易出现偏差的环节提出解决方法。对于方案二通过架下预留孔，装配前桁条上划线，预装桁条时使划线通过蒙皮装配孔中心的方法定位。最后详细对比两种方案的优劣，以保证产品质量为前提，选出较优的方案进行实施，保证了制品的正确装配。

Abstract: In order to solve the problem of harmonious assembly process of new stringer and old skin, two proposals are put forward. For the first scheme, the theoretical position of the assembly holes on the stringer is got by theoretical calculation and article measurement, and the solutions are put forward that is easy to appear deviation. For the second scheme, the assembly holes on the stringer are not manufactured before assemble, and they are made through the holes on the skin. A line is drawing on the stringer before it puts to fixture, and when preassembly, it puts the line through the center of the assembly hole on the skin. Finally, the advantages and disadvantages of the two schemes are compared in detail. On the premise of ensuring product quality, the better scheme is selected and implemented to ensure the correct assembly of products.
