文档介绍：汽车后桥壳体工艺卡具设计
摘要
毕业设计的课题基本分为两大类,即卡具设计和机床设计。本课题所涉及的是第一类,设计任务为汽车后桥壳体的工艺工装设计,在壳体内部装有主传动器、差速器、半轴等传动机构。
壳体起保证和支撑的作用,其主要加工表面为端面外圆、法兰平面、弹簧座平面、以及内孔等。
本次设计主要包括工艺规程、夹具、刀具和量具的设计。此次设计共分三个阶段,即:(1)毕业实习阶段(2)课题设计阶段(3)考核答辩阶段。结合本次设计零件的特点,在设计中完成工艺规程一套,夹具两套:(1)铣床夹具(2)钻床夹具,其中,前者为手动夹紧。本设计有铣床夹具图一张(A0),钻床夹具图纸一张(A0),铣床夹具图中间部分一张(A1),另外还有两张A3图纸,基本完成老师所交给的任务。

Automobile driving axle shell process fixture design
ABSTRACT
The subject of the graduation project is divided into three big classes,namely the frock designing type of craft ,making up the designingtype of lathe per subjects this subject involved is the first kind,designing the task for the rear axle of automobile,the craft frock of the shell is with anizations of the transmission,such as main hammer mechanism actuator,differential mechanism,semi-axis,ect,within the shell plays a role in guatanteeing and support,it processes flange,spring seat plane,and interior hole round for outside of the terminal surface of surface,ect,mainly。
This design includes the design of rules of craft,jig,cutter and measuring tool design divides three stages altogether,namely:(1)Graduation field work stage(2)Ddeign phase of subject(3)Examine the stage of bine this charateristic of designing the part,finisshes one set of rules of craft in the design,two sets of jigs:(1)Jig of the milling machine(2)The jig of the drilling machine,among them,the former,in order to clamp design the cutter sepatately according to the task book in addition—One milling cutter is with measuring,finish drawing amount nearlu 5 altogether,finish the task that a teacher assigns basically.
Key word:The rear axle of automobile;the crafu analuses;designs the task
