现代科学技术的发展在各个领域内的相互影响和促进越来越大。如电气技术上接近开关的定位精度已可达到0.02mm的程度,利用这一点,可使机械转台的自动分度机构变得相当简便。例一,我们研制的石油加油器计量器体壳体零件的镗铣加工专机。该壳体零件(见图1)上有A、B、C、D、E5个平面要精铣,A、B、C、D4个孔径须精镗。A、B孔同轴,C、D孔同轴,它们的轴线相互垂直;E
The development of modern science and technology has become more and more interdependent and promoted in various fields. Such as electrical technology proximity switch positioning accuracy can reach the level of 0.02mm, the use of this point, can make mechanical turret automatic indexing mechanism becomes very simple. Example 1, we developed a petroleum tanker meter body shell parts boring and milling plane. There are A, B, C, D, E5 planes on the shell parts (see Figure 1) to finish milling, A, B, C, D 4 holes to be fine boring. A, B hole coaxial, C, D hole coaxial, their axes perpendicular to each other; E
