典型夾具设计稿毕业设计稿说明书.docxVIP

摘要制造业中尤其是机械制造业，在产品生产过程中按照特定工艺，不论其生产规模如何，都需要种类繁多的工艺装备，而制造业产品的质量、生产率、成本无不与工艺装备有关。随着不规则形状零件在现代制造业中的广泛应用，如何保证这类零件的加工精度就显得尤为重要，随着社会技术的发展，机械的应用越来越广泛，在机械结构组成的中，轴承占据着重要地位，与之对应的轴承端盖的快速设计加工也越来越重要，因此零件应具有足够的强度、钢度耐磨性和韧性，以适应端盖的工作条件，是非常重要的机械零件之一，轴承端盖应用广泛，所以端盖的夹具设计是影响夹具加工的重要因素，机械制造过程中用来固定加工对象，使之占有正确的位置，以接受施工或检测的装置，又称夹具。从广义上说，在工艺过程中的任何工序，用来迅速、方便、安全地安装工件的装置，都可称为夹具。夹具通常由定位元件（确定工件在夹具中的正确位置）、夹紧装置 、对刀引导元件(确定刀具与工件的相对位置或导引刀具方向)、分度装置（使工件在一次安装中能完成数个工位的加工，有回转分度装置和直线移动分度装置两类）、连接元件以及夹具体（夹具底座）等组成，在端盖的夹具设计中，主要从夹具这几个组成方面来设计。关键词：机械制造，夹具，轴承端盖 AbstractEspecially machinery manufacturing in the manufacturing industry, the production process according to a specific process, regardless of their size, requires a wide range of technology and equipment, and manufacturing all product quality, productivity, cost and process equipment. As not rules shape parts in modern manufacturing in the widely application, how guarantee this class parts of processing precision on is particularly important, as social technology of development, machinery of application increasing widely, in machinery structure composed , bearing occupy with important status, and of corresponds to of bearing end cover of fast design processing also increasingly important, therefore parts should has enough of strength, and steel degrees wear sexual and toughness, to adaptation end cover of work conditions, is very important of machinery parts one of, bearing end cover application widely, Fixture design for end cover are important factors affecting Jig machining, machinery used in the manufacturing process, stationary processing object so that it occupies the correct position to accept construction or inspection devices, also known as the fixture. Broad said that any process in the process used to quickly, easily and securely install the workpiece device, can be called a fixture. Fixture usually by positioning components (determines workpiece in fixture in the of correctly location), and clip tight device, and on knife boot components (determi
