2、置和加工準(zhǔn)確性我們一定在加工底面的時(shí)間通過畫線找出底面的加工余量。這樣就可以更好的保證孔17的位置和加工精度!加工孔14的夾具其實(shí)就是在加工底面夾具的基礎(chǔ)上加了一個(gè)45度斜度板。加工孔17的時(shí)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(jì)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(jì)的夾具就具有對孔17的夾具定位準(zhǔn)確,和加工時(shí)間的震動小,那就得在孔17的附近找個(gè)定位加緊點(diǎn)!關(guān)鍵詞加工工藝,夾具,尾座體,設(shè)計(jì)I攀枝花學(xué)院本科畢業(yè)設(shè)計(jì)(論文)ABSTRACTABSTRACTThistopicismainlydesi
