2、。專用夾具也有很大的應(yīng)用空間,即通過專用夾具達(dá)到定位準(zhǔn)確、夾緊迅速、操作快捷等優(yōu)點(diǎn),易于保證,并通過繪圖軟件完成了銑床夾具裝配圖及零件圖的設(shè)計(jì)。[關(guān)鍵詞]:銑床夾具、凸輪軸、溝槽、V形塊(空一行)19TheMillingPartkeywaydedicatedfixturedesign[Abstract]generallyusedformillingmachiningplane,grooves,gapsandformingsurface.Millingjigisalsoacommonfixture.Thedesignofthefixtureisusedinhorizontalmill
