CA1092汽车连杆机械加工工艺规程及专用夹具设计【毕业论文+CAD图纸全套】.doc

本科学生毕业设计（论文） CA1092汽车连杆机械加工工艺规程及专用夹具设计 学 生： 学 号： 指导教师： 专 业： 机械工程学院 二O 年六月 摘 要 该文首先进行了连杆的零件分析，通过对参考文献进行的分析与研究，阐述了工艺、和制造技术等的相关内容；在技术路线中，论述连杆工艺的加工工艺，加工顺序的安排。为毕业设计写作建立了进度表，为以后的设计工作提供了一个指导。最后，给出了一些参考文献，可以用来查阅相关的资料，给自己的设计带来方便。 该设计根据所给的连杆的零件图、技术要求和加工批量及设备、设计出适合于该连杆的加工工艺和端面铣夹具。为了实现大批量生产，机床按连杆的机械加工工艺过程连续排列，且多为专用机床。毛坯由模锻获得，采用连杆体和连杆盖合锻，提高了材料的利用率，有利于组织和生产管理。加工时装夹也比较方便，论文还根据零件特征设计了专用夹具。整个设计的指导思想是“简便、高效、经济”地生产出符合要求的产品。 关键词：连杆，加工工艺，专用夹具 ABSTRACT This paper first analyzed the connecting rod, through parts of the reference for analysis and research, this paper expounds the process, and manufacturing technology related content; In technical route, discusses linkage process processing technology, processing order arrangement. Writing for the graduation design for later established schedules, the design work provides a guidance. Finally, we give some reference, can be used to access relevant information, to give their design, bring convenience. This design according to the connecting part drawings, technical requirements and processing batch and equipment, design a suitable for the connecting rod processing technology and end milling fixture. In order to realize the mass production, machine machining process according to the process of connecting, and more for continuous arranged a special machine. Blank, the connecting rod won by forging close connecting head bodies and forging, improve the material utilization, be helpful for organization and production management. Processing fashion clip is more convenient, this paper also according to the special jig design part features. The whole design is the guideline of the simple and efficient, economy to produce to meet the requirements of products. Key words：Connecting rod ，Processing technology，Special jig 中文摘要 I ABSTRACT II 1 绪论 1 1.1机床夹具的现状 1 1.2现代机床夹具的发展方向 2 1.3 问题的提出 2 1.4基本概念和理论基础 3 1.4.1加工工艺 3 1.4.2机床的夹具应满足的要求 3 2 连杆的加工工艺设计 4 2.1连杆的功用与结构分析 4 2.2连杆的工艺特点 4 2.3.定位及夹紧 5 2.4连杆的主要技术要求 5 2.5连杆的
