GY02-082@“汽车主动伞齿轮”的工艺工装设计_,机械毕业设计全套

内容简介：

I 摘 要 此毕业设计的课题是 “ 汽车主动伞齿轮 ” 的工艺工装设计。 其中介绍了主动伞齿轮从毛坯变成成品的一个完整的机械加工过程，此书包含了机械加工工艺规程的制定，专用夹具设计，专用刀具设计，专用量具设计四章主要内容。 第一章介绍了此零件的工艺分析，加工类型，选定毛坯并且制定了加工工艺。 第二章为此设计书的重点章节，本书以两套专用夹具为例，详细的阐述了典型工序中的专用夹具的设计过程。其中包括了夹具功能简图和工作原理，夹具的定位方案设计（定位方式、元件等），夹具的定位误差分析，切削力及夹紧力的计算，夹具的夹紧装置或机 构设计，夹具动力装置设计。通过对此章的阅读，可以详细了解夹具的设计方法和过程，并且可以当作典型例子去应用到其他零件的机械加工工艺中的夹具设计。 第三章为专用道具设计，第四章为专用量具设计，其中有详细步骤及公式，多可以借鉴此章进行设计。 通过对此书的阅读，可以独立完成汽车伞齿轮的工艺工装设计，可以说此书是汽车主动伞齿轮工艺工装设计的专用机械加工手册 关键词： 汽车；伞齿轮；夹具；刀具；量具 ntsII Abstract This graduation project topic is the design of “the automobile driving bevel gear” craft work clothes. Introduced a completed machine-finishing process that the driving bevel gear turns the end product from the semifinished materials. This book contained four chapter of primary coverages that is the machine-finishing technological process formulation, the unit clamp design, the special-purpose cutting tool design, the special-purpose measuring instrument designs. First chapter introduced this components craft analysis, the processing type, the designation semifinished materials and formulat the processing craft. The second chapter is the key chapter of this book.This book take two grip designs s as an example.It expound detailed design two grips in a model of a production processes.It contains the photo of the grip function , design a way for locating the grip(a way for locating, element and so on).,the positioning error analysis of the fixrture, the calculation of cutting force and the clamping force , the clamping device or mechanism design of fixtures, the power plant design of Fixture. Through reading this chapter, you can learn more about the fixture design methods and processes, and can act as a typical example to apply to design other parts of the machining process in the fixture design field. Chapter III as props for the design, chapter IV for measuring tool for the design, including the detailed steps and formula, most of the design can be draw on this chapter. Through reading this book, you can complete an independent automotive bevel gear technology tooling design, the book is the vehicle that can take the initiative to bevel gear technology Equipment designed for manual machining.
