有些管连接件,虽单个零件加工精度很高,但零件相互装配连接精度却很差,连接处管口常产生错位偏斜,如图1所示。下面简述其原因及消除方法。一、装配误差分析以下各图标一个字母的管口表示钻孔定位基准,标两个字母的管口表示零件装配后钻孔定位基准重合 Some pipe connectors, although the processing accuracy of a single part is very high, but the assembly accuracy of the parts are poorly assembled with each other, the connection nozzle often produce misalignment, as shown in Figure 1. The following brief description of the reasons and ways to eliminate. First, the assembly error analysis The following icon a letter of the nozzle that drilling positioning benchmark, the standard two-letter nozzle said that after the assembly of the drill hole positioning reference coincidence
