南京理工大学泰州科技学院毕业设计说明书(论文)作 者:孙江锋学 号：0601510146学 院:机械工程学院专 业:机械工程及自动化题 目:制订LH180MQ左箱体工序卡及铣镗结合面夹具设计 高级工程师 梁红军指导者： 评阅者： 2010 年 6 月毕业设计说明书（论文）中文摘要左箱体的加工质量将直接影响机器的性能和使用寿命。本次设计旨在提高左箱体的加工效率，由此我们首先对左箱体的结构特征和工艺进行了仔细的分析，然后确定了一套合理的加工方案，加工方案要求简单，操作方便，并能保证零件的加工质量。夹具结构设计在加深对课程基本理论的理解和加强对解决工程实际问题能力的培养方面发挥着极其重要的作用。利用更好的夹具可以保证加工质量，机床夹具的首要任务是保证加工精度，特别是保证被加工工件的加工面与定位面以及被加工表面相互之间的位置精度；提高生产率、降低成本，使用夹具后可以减少划线、找正等辅助时间，且易于实现多工位加工。扩大机床工艺范围，在机床上使用夹具可使加工变得方便，并可扩大机床工艺范围。减轻工人劳动强度，保证生产安全。为了让夹具有更好的发展，加快用高新技术改造和提升夹具技术水平的步伐，创建夹具专业技术网站，充分利用现代信息和网络技术，与时具进地创新和发展夹具技术。本次设计是制订LH180MQ左箱体工序卡及铣镗结合面夹具设计，设计正确的加工工艺路线。这次设计涉及到机床，机械加工工艺，工装夹具等机制专业的几乎所有的专业基础知识。是一次全面地，系统地检查自己在大学期间对专业知识学习的情况，在整个设计过程中做到严谨认真，一丝不苟的精神，尽量使自己的设计达到理想的水平，通过独立的查找资料，分析，计算完成方案设计，图纸设计和编写技术文件等，设计了这套比较完整的加工工艺路线，使自己对机制专业有了更深刻的认识。关键词 工艺规程 夹具设计 左箱体毕业设计说明书（论文）外文摘要Title Make LH180MQ Left Box Process Card andMilling Boring With Surface Fixture Design AbstractThe processing quality left box will directly influence the machine performance and long service life. The design aims to improve the machining efficiency left box, we first left box structure characteristics and process the careful analysis, then determines a reasonable set of processing scheme, the processing plan requirement is simple, easy to operate, and can ensure the process quality of parts.Structure design of fixture in the course of the basic theory of understanding and strengthening the ability to solve practical problems in cultivating play a very important role. Using better fixture can ensure the process quality and the machine tools fixture priority is to ensure machining accuracy, especially that of the machining process and positioning surface and processed surface between the position precision, Improve productivity and reduce cost, use fixture after is crossed, can reduce the auxiliary time, and is easy to realize the multistage process. Expand machine technology, in machine can make use of jigs, and easy machining scope expanding machine craft. To reduce the labor intensity, ensure the safety in production. In order to make better development, clamp with high-tech transformation and accelerate the pace of ascension fixture technology level, professional technology to create fixture, make full use of modern information websites and network technology, with land development and innovation fixture technology.This design is LH180MQ formulation process card and left box with surface milling and boring fixture design, design the correct processing route. This design involves machine, mechanical processing, jig professional mechanism of almost all the basic specialized knowledge. A comprehensive, systematic examination oneself in university period of professional knowledge, in the whole process of design, meticulous carefully accomplish precise of spirit, try to make yourself to achieve the desired level of design, through the analysis of the independent calculation, searching information, complete design, drawing design and technical documents written, d
