2、實就是在加工底面夾具的基礎(chǔ)上加了一個45度斜度板。加工孔17的時間為保證相對于A和B面的平行度我們就得要準(zhǔn)確的設(shè)計出以A和B面定為的夾具！還考慮到工件的圓度和圓柱度的誤差小，我們設(shè)計的夾具就具有對孔17的夾具定位準(zhǔn)確，和加工時間的震動小，那就得在孔17的附近找個定位加緊點！關(guān)鍵詞加工工藝，夾具，尾座體，設(shè)計IIABSTRACTThistopicismainlydesignthatdesignsthetailabodyofsometoolmachinetoprocessthecraftandtongses,adoptingtodesignfir
