K31-泵体的加工工艺及钻5-M5螺纹底孔夹具设计（全套含CAD图纸）.zip

I 摘要在机床上加工工件时,定位和夹紧的全过程称为“安装”。在机床上用来完成工件安装任务的重要工艺装备,就是各类夹具中应用最为广泛的“机床夹具”。机床夹具的种类很多,其中,使用范围最广的通用夹具,规格尺寸多已标准化,并且有专业的工厂进行生产。而广泛用于批量生产,专为某工件加工工序服务的专用夹具,则需要各制造厂根据工件加工工艺自行设计制造。本设计的主要内容是设计车床夹具和铣床夹具,需要对泵体钻 5-M5 螺纹底孔夹具设计。泵体零件上往往都有各种不同用途和不同精度的孔需要加工。在机械加工中,孔的加工量所占比例较大,其中钻头、扩孔钻、铰刀、镗刀等定尺寸***加工占相当多数。这时, 除了要保证孔的尺寸精度外,还要达到孔的位置精度要求。在单件小批量生产中,用划线后找正孔轴线位置方法加工。在批量生产中一般都采用钻床夹具与镗床夹具,钻床夹具又称钻模,镗床夹具又称镗模,通过钻套、镗套引导***进行加工可准确地确定***与工件之间的相对位置。关键词: 通用夹具专用夹具钻床夹具车床夹具 II Abstract In the machine machining, positioning and clamping process called "installation". The machine used plete the task of work piece installation of process equipment, is an important fixture in the most widely used "the machine tool's fixture. There are many kinds of the machine tool's fixture, among them, use the widest range of general fixture, size, and there has been more standardized professional factory production. And widely used in mass production, designed for a work piece machining processes and special fixture service to the factory according to the work piece machining process to design and manufacture. The design of the main content is boring and milling machine fixture design jigs, need to pump. Pump body parts are usually different purposes and accuracy of the hole machining. In machining, the hole of manufactured, among which the proportion of drilling, reaming, reamer, boring tools for size of such a sizable majority. At this time, except to ensure the accuracy of the size of the hole hole, but also achieve the position precision requirements. In single small batch production, use crossed for positive hole axis position after processing methods. In batch production in general by drilling and boring fixture, drilling fixture and diamond fixture, boring fixture and say, boring, boring set by drilling tools for processing guide can accurately determine tool and the relative position between the work piece.
