图示的差速器球面Sφ98mm±0.05mm,相对于壳中心的位置度为φ0.02mm,相对于φ18H7孔的同轴度为φ0.03mm,位置公差要求较严。在大批量生产中,我厂是在卧式车床上采用图中所示工装和成形球面刀加工差速器壳内球面的。首先去掉小刀架,矩形支承4安装在车床的中滑板 The illustrated differential spherical surface S98 is 98 mm ± 0.05 mm, the position relative to the center of the housing is φ0.02 mm, and the coaxiality with respect to the φ18H7 hole is φ0.03 mm. The position tolerances are more stringent. In high-volume production, our factory is in the horizontal lathe tooling and forming spherical knife shown in the processing differential spherical spherical shell. First remove the knife holder, rectangular support 4 installed in the lathe in the skateboard
