摘 要关键词：；； Heart axial workpiece and its milling machine processing of 3 d design and fixture simulation Abstract This paper conform to the mechanical design and manufacture of digital visualization, intelligent trend . On the basis of the traditional mechanical design , the implementation of three-dimensional design , making the traditional design and modern design combine to maximize design efficiency The paper to complete the ring is used for milling notch special fixture , the end of the small axis milling plane fixture 3D design and modeling . Including the analysis of the orientation program of the fixture , clamping program , folder specific and positioning key design and machining accuracy . 3D assembly drawings to complete each set of fixtures and generate two-dimensional assembly engineering drawings . And loaded as part of a mechanical fixture manual Gallery Project Gallery software system The solidworks 3D software design, mechanical fixture , greatly reducing the workload of the designer , and makes the design of the target image, uncertainty , and high accuracy . Modern digital design and manufacturing is particularly important in the mechanical field Key Words: milling fixture; heart axial workpiece; three dimensional design 主要符号表 M 弯矩 F 力 n 转速 ap 背吃刀量 T 寿命 d 直径 f 进给量 L 长度 P 功率 t 时 目录 摘 要 I Abstract II 主要符号表 III 1 绪论 1 1.1研究的目的及意义 1 1.2国内外发展及研究状况 1 1.2.1国外发展状况 1 1.2.2国内发展状况 2 1.2.3机械夹具未来发展方向 2 1.3本课题研究的内容 3 1.3.1研究内容 4 1.3.2研究意义 4 2铣床专用夹具原理与设计 6 2.1铣床夹具的主要类型 6 2.2铣床专用夹具设计要则 6 2.2.1铣床专用夹具的选择原则 6 2.2.2结构设计要则 6 3环形工件铣槽口夹具设计 8 3.1零件的结构分析 8 3.2零件的加工工艺分析 8 3.3夹具结构设计 10 3.3.1夹具设计步骤 10 3.3.2定位方案选择 10 3.3.3定位基准的选择 11 3.3.4定位元件的设计 11 3.3.5夹紧机构的设计 12 3.4其他元件的设计 13 4.1零件的结构分析 15 4.2零件的加工工艺分析 15 4.3夹具的结构设计 15 4.3.1定位基准的选择 15 4.3.3夹紧机构的设计 16 4.4其他元件设计 17 6总结 20 参考文献 21 1 绪论 1.1研究的目的及意义 夹具是能够使产品按一定的技术要求准确定位和牢固夹紧的工艺装置，它的主要用于保证产品的加工质量、减轻劳动强度、辅助产品检测、展
