内容简介：

摘 要本设计的内容包括了柴油机机体的机械加工工艺过程及其中工序的夹具设计。 本设计中加工工序内容主要有铣端面、镗孔和钻孔等。 在制定工艺过程中，要确定各工序的安装工位和该工序需要的工步, 加工各工序的机车及机床的进给量、主轴转速、切削速度和切削工时。然后进行镗孔夹具设计,首先应考虑工件的定位与夹紧。选择合适的定位元件和夹紧元件可以节约工时、提高工作效率。其次是引导装置。在选择元件时,应该尽量选择标准件。最后计算该工序的基本时间、辅助时间和工作地服务时间。关键词 工序、定位、夹紧、夹具设计ABSTRACTThis 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
