裝配圖柴油機(jī)機(jī)體機(jī)械加工工藝及其Φ66鏜孔夾具設(shè)計(jì)

裝配圖柴油機(jī)機(jī)體機(jī)械加工工藝及其Φ66鏜孔夾具設(shè)計(jì),裝配,柴油機(jī),機(jī)體,機(jī)械,加工,工藝,及其,66,鏜孔,夾具,設(shè)計(jì) 摘 要 本設(shè)計(jì)的內(nèi)容包括了柴油機(jī)機(jī)體的機(jī)械加工工藝過(guò)程及其中工序的夾具設(shè)計(jì)。 本設(shè)計(jì)中加工工序內(nèi)容主要有銑端面、鏜孔和鉆孔等。 在制定工藝過(guò)程中，要確定各工序的安裝工位和該工序需要的工步, 加工各工序的機(jī)車及機(jī)床的進(jìn)給量、主軸轉(zhuǎn)速、切削速度和切削工時(shí)。然后進(jìn)行鏜孔夾具設(shè)計(jì),首先應(yīng)考慮工件的定位與夾緊。選擇合適的定位元件和夾緊元件可以節(jié)約工時(shí)、提高工作效率。其次是引導(dǎo)裝置。在選擇元件時(shí),應(yīng)該盡量選擇標(biāo)準(zhǔn)件。最后計(jì)算該工序的基本時(shí)間、輔助時(shí)間和工作地服務(wù)時(shí)間。 關(guān)鍵詞 工序、定位、夾緊、夾具設(shè)計(jì) ABSTRACT This design content has included the diesel engine organismmachine-finishing technological process and its center the workingprocedure jig design. In this design processes the working procedurecontent mainly to have the mill end surface, boring and the drill hole and so on. In the formulation technological process, must determine various working procedures the installment location and this workingprocedure need the labor step, processes various working procedures the locomotive and engine bed entering for the quantity, the main axleotational speed, the cutting speed and the cutting man-hour. Then carries on boring the jig design, first should consider the work piece the localization with clamps. Chooses the appropriate localization part and clamps the part to be allowed to save man-hour, the enhancement working efficiency. Next is the guiding arrangement. When chooses the part, should choose the standard letter as far as possible. Last count this working procedure basic time, non-cutting time and job site service time. Keywords： The process, The localization, clamps, jig design II
