设计简介
摘 要
本文通过对电动机机座底面孔位的研究,为保证其底面上4个孔的位置公差,结合对组合机床的特点,设计出了专门用来加工该型号电动机机座底面底孔组合机床的多轴箱。
通过对通用机床多轴箱零件的研究,设计出了组合机床专用多轴箱,具有成本低,效率高的特点。组合机床设计时采用了“基准统一”的原则,以上一道加工工序的基准面为定位基准面,保证机座底面孔位的形状、位置精度的同时又降低了机座整体的累积误差。组合机床总体设计时采用了“三图一卡”的设计原则,既满足了加工要求,又保证了机床的相对生产率。

ABSTRACT
Based on the study of position of underside of the electric motor frame, in order to ensure position tolerances of the 4 holes, combined with the characteristics of combination machine tool, this paper designs the multi-axle box of combination machine tool for underside of the electric motor frame.
Through the study of general machine tool spindle parts, the multi-axle box is designed with the advantages of low cost, high efficiency. The "Unification Datum" principle is taken into account the datum of the fixture is the one that last machining process used. In this way, the shape and position precision is ensured and reduces the accumulated error of the whole. The design principle of "three charts and a card" of the overall design of machine tool is used , not only to meet the processing requirements, but also to ensure the relative productivity of the machine tool.
