在制造飞机型架及其他工艺装备时,常需建立一个空间座标系,以便将需要安装的型架元件迅速而又准确地置于规定的空间位置。目前在型架安装工艺中,不论是具有空间座标系的专用型架装配机,还是用于现场安装的工具轴,每个座标方向上的尺寸要求,大多是通过一排孔距为200±0.01毫米的φ12H7孔和一套可变距的插孔板来保证的。由于尺寸传递和转换环节较多,工人操作水平不一致, In the manufacture of aircraft frame and other process equipment, often need to establish a space coordinate system, in order to be installed in the frame elements quickly and accurately placed in the specified space position. At present, in the frame mounting process, whether it is a special frame mounting machine with a space coordinate system or a tool shaft for on-site installation, the size requirement in each coordinate direction is mostly through a row of holes with a pitch of 200 ± 0.01 mm φ12H7 hole and a set of variable distance jack board to ensure that. Due to the size of the transfer and conversion of more workers inconsistent level of operation,
