在制造型架及其他工艺装备时,常常需要建立一个精确的空间座标系,以便将需要安装的型架元件迅速、准确地置于规定的空间位置上。目前,在型架制造工艺中,不论是具有空间座标的专用设备型架装配机,还是用于现场安装的工具轴,每个座标方向上的尺寸,大多是通过一排孔距为200±0.02毫米的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,加之孔和销子的磨损,因此,积累误差较大,影响型架的安装精度,进而影响了
In the manufacture of racks and other process equipment, it is often necessary to establish an accurate spatial coordinate system in order to quickly and accurately place the racks to be installed in the specified spatial locations. At present, in the frame manufacturing process, whether it is a special equipment rack assembly machine with space coordinates or a tool shaft for on-site installation, the size in each coordinate direction is mostly through a row of holes with a pitch of 200 ± 0.02 mm holes and a set of variable distance jack board to ensure that. Due to the size of the transfer and conversion more links, workers at different levels, combined with the hole and the pin wear, so the accumulation of error is larger, affecting the installation of precision-type frame, thereby affecting the
