一种大型转运车的同轴度检测方案

A Coaxiality Detection Scheme for Large Transfer Vehicle

舱体转运车是大型空间站舱体转运装置的重要部件,它的位置精度直接影响了空间站舱体中各舱段的协调能力。本文从转运车的结构分析入手,分析了大型转运车同轴度检测过程中存在的问题,并指出了检测难点。针对检测难点,提出了一种采用标尺和经纬仪配合测量的检测方法。该方法先确定大型架车水平方向和垂直方向基准尺寸,再计算得出同轴度。试验结果表明本文提出的方法检测精度高于0.05mm,满足转运车实际使用要求,对提高大型舱体转运的生产效率检测质量具有重要意义。

The large transfer vehicle is an important component of the cabin transfer device of a large space station,and its position accuracy directly affects the coordination ability of each cabin in the space station cabin.This article starts with the structural analysis of the transfer vehicle,analyzes the problems in the coaxiality detection process of the large transfer vehicle,and points out the detection difficulties.Aiming at the difficulty of detection,this paper proposes a detection method that uses a ruler and theodolite to measure together.This method first determines the horizontal and vertical reference dimensions of the large-scale frame,and then calculates the coaxiality.The test results show that the detection accuracy of the method proposed in this paper is higher than 0.05mm,which meets the actual use requirements of transfer vehicles,and is of great significance for improving the production efficiency of large-scale cabin transfer.
