1、 - I - 汽车差速器内球面铣削快速换刀装置 - II - 摘摘 要要 通过对差速器结构的分析，明确差速器需要加工的内球面，了解差速器的具体 尺寸进而确定换刀装置的尺寸大小和在哪个方向进行插入换刀装置进行换刀。所要 设计的是在加工之前通过换刀装置快速的把刀具送到数控铣床的刀柄处，再加工之 后再快速的把刀具取出。带动滑轨的装置是导杆机构，为了防止在送刀的时候发生 偏移和旋转设计的是轨道的形式，确保换刀的时候能够准确。换刀装置的床身能够 通过夹具夹到数控铣床的工作台上，节省空间和零件材料。 关键字：关键字：卡刀具；直线导轨；导杆；床身底座 - III - Abstract Through the
