毕业设计（论文） 题 目：法兰盘加工工艺及夹具设计 系 别：机电系 专 业：机械制造及其自动化 年 级：11-2 姓 名：杨柳 指导教师：周燕 日期: 2015年 5月29日 摘 要 工艺学是钻研机械加工工艺技术和夹具设计为主要目的的技术学科,具有非常强的实践性,要求在学习过程中紧密的联系生产与实践,并且它又拥有非常强的综合性。 本次毕业设计研究的课题为法兰盘加工工艺及夹具的设计，其主要研究内容为： 首先，对工件进行分析，主要是先分析零件的作用、结构和工艺，经由零件分析可以了解零件的基本构造，然后通过工艺分析了解工件的加工要求。通过零件图要求的的具体加工，确定毛坯的制造样式与尺寸。 其次，对基面进行选择，确定加工的粗基准和精基准。选好基准，制定工艺加工路线，再确定能够使零件的形状、尺寸精度还有位置精度等要求达到完全保证的加工工艺方案。 再次，根据已经确定的加工工艺方案，选择加工设备，决定每一工步的切削量和时间。 然后，设计指定法兰盘12mm斜孔的夹具。分析设计任务，确定定位基准，决定夹具结构方案，然后对切削力、夹紧力，定位误差进行计算。 最后，把整个设计过程整理为设计说明书和指定的图纸，所有设计完成。 关键词： 12mm斜孔法兰盘；加工工艺；设计夹具 Abstract Technology is the technology research of mechanical processing technology and fixture design for the main purpose, has very strong practical requirements in the learning process, contact closely and production practice, and it also has a very strong comprehensive. The graduation design topic for the flange and fixture design process, the main research contents are as follows: First of all, on the workpiece is analyzed, the main is to analyze the function, structure and process of parts, through the parts analysis to understand the basic structure of parts, and then through the process analysis to understand the machining requirements. By drawing the specific processing requirements, determine the style and size of manufacturing blank. Secondly, the selection of base, determine the processing of coarse and fine reference base. Choose the benchmark, the development process of processing route, and then determine the shape, size precision and can make the position precision requirements of the parts to achieve processing scheme fully guaranteed. Again, according to the process scheme has been determined, the choice of processing equipment, decided every steps of cutting quantity and time. Then, the fixture design specified 12mm flange hole. Analysis of the design task, determine the location, determine the fixture structure, then the cutting force, clamping force, position error calculation. F
