通常在车床上加工内球面是采用带有蜗轮副的车球面刀架,靠手工操作进行的。其缺点是工具复杂,不易对刀调整,加工出的内球面尺寸精度和面轮廓度低,特别是当被加工零件的端面对内球面的球心有较高的位置精度要求时,更不能保证加工要求。本文所介绍的内球面加工工具是我厂在差速器壳体等零件的加工实践中,所设计、制造成功的一种加工精度高,应用范围宽,结构简单,操作方便的内球面加工工具。该工具根据被加工内球面的形状不同分 The inner spherical surface is usually machined on a lathe using a spherical spherical tool holder with a worm gear pair that is manually operated. The disadvantage is the complexity of the tool, difficult to adjust the knife, the processing of the inner spherical surface accuracy and surface profile is low, especially when the workpiece is the inner surface of the spherical end of the ball has a higher position accuracy requirements, not to mention Ensure processing requirements. This article describes the spherical tool is my factory in the differential casing and other parts of the processing practice, the design, manufacture a successful processing of a high precision, wide range of applications, simple structure, easy operation of the spherical tool . The tool is processed according to the different shape of the inner sphere
