在加工 YB 系列电机后端盖和立式端盖时,传统的方法是以装配止口定位,装在法兰(如图1)上加工轴承室及安装止口,这样法兰定位止口和工件止口之间的间隙要求较高,拆装困难.工艺上要求法兰在每次装上机床时需重车定位止口.耗费了大量的法兰.现推荐一种改进的法兰结构(如图2).此结 YB series motor in the processing of the rear end cover and vertical end cover, the traditional method is to locate the positioning of the assembly, installed in the flange (Figure 1) on the processing of bearing housing and installation of the stop, so flange positioning stop and The gap between the workpiece requires a higher gap, disassembly difficult process requirements flange each time the machine is loaded with heavy truck positioning stop. Spent a lot of flange. Now recommend an improved flange structure (Figure 2). This knot
