中文摘要及关键词 摘要：工艺设计是产品制造过程中技术准备工作的一项重要内容，是产品设计与实际生产的纽带，是一个经验性很强而且随制造环境变化而多变的决策过程。通过有效的工艺方法和工艺装备保证产品质量；合理的工艺参数和标准的工艺过程提高生产效率或缩短生产周期； 最大限度地利用有限资源，减少生产准备时间和减低生产成本Abstract: Process design and fixture design is an important element of the technical preparations for manufacturing process, product design and production ties, is a highly empirical and changing with the changes in the manufacturing environment and the decision-making process. Through effective process and technology and equipment to ensure product quality; reasonable parameters and standards process to improve production efficiency or shorten the production cycle; maximize use of limited resources, reduce production time and reduce production costs.This design instruction booklet analyze the planning of lathes tailstock, and fix a detailed process planning from semi-finished product to finished product, make a mechanical manufacturing operational planning. Design a drill with the jig. This jig including the clamp, the side bar, drills traces parts，board, column, V block and so on. Its biggest characteristic is that it is an attire clamps then they can the forming to drill the processing, favors the enhancement processing efficiency and the product processing quality, which can be learned by others. Designs drilling with the jig can precisely realize the localization in the components processing process with to step up, clamps the operation with the fashionable clothing to be more convenient, can play the huge role in the components production process. Keywords：Lathe main axle，Drills the template , Technological process, Drill with the jig. 1 绪论 1.1 课题的目的及意义 本课题是关于工艺规程设计和夹具设计，通过本设计，要求提高学生在机械方面的各方向的能力，能够成为名副其实的21世纪新型人才，成为一名合格的本科毕业生。 通过全面复习、大量的阅读相关的资料，大大的巩固机械制造工艺学、机械制造装备设计、机械设计、夹具设计、工艺规程设计等课程，加深对一些相关课程的基本知识了解和掌握，使学生能够运用所学知识解决一些实际设计的基本问题，可以完成毕业设计。同时提高其分析问题、解决问题的能力，进一步加强其机械制图的能力，进一步掌握机械制图的各种软件。熟悉应用并掌握各种手册、文献资料在工艺工装设计中的运用。查阅各种国标，提高对标准件的认识。通过文献检索、英文翻译、机械制图，提高运用计算机和英语的能力，提高动手能力，提高综合素质。 随着经济全球化和我国经济的快速发展,我国
