差速器壳体机械加工工艺规程与专用夹具设计太原科技大学 华科学院 机自082216H 李芸 200822010679 指导教师：张学良摘要：机械加工工艺设计师一门融理论性、科学性、实用性和经济性为一体的设计，它涉及的知识面广，决定着零件的加工质量、生产成本、产品效益及单位的经济效果。因而，正确分析零件的功用，恰当合理地制定工艺规程；选定机床、刀具、量具；夹具设计；确定加工余量、切削用量，对提高产品质量、劳动生产率、减轻劳动强度等具有重要的意义。汽车差速器是驱动轿的主要部件。它的作用就是在向两边半轴传递动力的同时，允许两边半轴以不同的转速旋转，满足两边车轮以不同转速运动，减少轮胎与地面的摩擦。汽车发动机的动力经离合器、变速器、传动轴，最后传送到驱动轿再左右分配给半轴驱动车轮，在这条动力传送途径上，驱动轿是最后一个总成，它的主要部件是减速器和差速器。本设计主要设计差速器壳体工艺规程的制定及夹具。第一部分是差速器壳体的工艺规程的制定。首先对零件的作用与原理加以了解，然后根据零件图，进行工艺分析，按照供需设计的各项规定，选择毛坯，制定一个技术要求和经济上比较合理的工艺路线。再查表确定加工余量，选择刀具及制定出一套完整的工序卡。第二部分是夹具设计，本夹具专为钻孔而设计，设计普通机床能使用的夹具，然后用CAD画出来。关键词：差速器壳体；加工工艺；夹具The Machining Process Planning and Special Fixture Design of the Differential ShellTaiyuan University of Science and Technology Huake College Mechatronic Engineering 082216H Li Yun 200822010679 Director：Zhang XueliangAbstract：Machining technology design is a design that includes theoreticals, scientific, operating characteristics and economic. It involved wide knowledge, decided the working quality, manufacture cost, products benefit and economic effect of one product. Thus, correct analyse the function of the parts, appropriate compile technological procedure, selected machine, tool, measuring implement, design clamp, define allowance, cutting quantity, have important meaning for improving products quality, labour productivity, reduce labour intensity etc.Differential shell is an important part in automobile. Its function is to pass power in both sides of half shaft at the same time, allowing both sides of the half shaft rotation at different speeds, to satisfy both sides of wheels rotation at different speeds, reduce the friction between the tire and the ground. Automobile engine via a clutch, gearbox, transmission shaft, finally transmitted to the drive elevator control again assigned to the axle driving wheel, in this article the power transmission path, drive axle is a final assembly, its main component is the reduction gear and differential. The main design is the design of process regulation and fixture of the differential shell. The first part is the Process regulation of the differential shell. First of all is to understand the action and principle of the parts, then based on the part drawing and carry on the process analysis, according to the supply and demand of the provisions of the design and choice the blank, to formulate a technical requirements and economically reasonable process route. Check table for determining the machining allowance, choose tools and to formulate a complete set of process card. The second part is the fixture design, this fixture is designed for drilling tha
