沈阳化工大学科亚学院 本科毕业论文 题 目： 专 业： 班 级： 学生姓名： 指导教师： 论文提交日期：2016年 6月 1日 论文答辩日期：2016年 6月 6日 摘要 本课题的内容主要分为推动架零件加工工艺规程设计和底孔夹具设计两大部分。首先，通过对B6065刨床推动架零件的分析，认识到推动架在B6065刨床中加工中时起的作用。运用机械加工制造技术及相关课程的一些专业知识，解决推动架在加工过程中的安装、定位、加紧以及合理的工艺路线的安排等方面的相关问题，依照图纸确定相关的工艺尺寸及选择合理的机床和刀具，保证零件的加工要求。其次，依照推动架毛坯件和生产成本要求及各加工方案的比较，拟定出合理可行的推动架加工工艺规程路线。最后，依照被加工零件的加工要求，参考机床夹具设计手册及相关方面的资料，运用夹具设计的基本原理和方法，拟定夹具设计的方案，设计出节省时间节省资源并且能保证加工质量的夹具。 夹具设计的主要内容是推动架钻床专用夹具，经老师协商，决定设计第7工序的工装夹具。钻M8底孔φ6.6，攻M8孔的钻床夹具。夹具是利用φ35两端面和φ50两端面进行定位，利用M14以及压板对零件进行夹紧；再配合一个个定位销进行钻φ6.6孔。端盖与底座还有推动架零件两个中心孔平行度为0.1。钻完孔后攻M8螺纹。 关键词:加工制造、工艺规程、底孔夹具、推动架 Abstract Contents of this project consists of promoting the machining process planning and fixture design of bottom two parts. First of all, through the analysis of B6065 Planer to promote aircraft parts, recognizing that promotion plays a role in processing in the B6065 Planer. Use some expertise in machining technology and related courses, resolved to promote in the process of installing, positioning, and a reasonable route arrangements and other related issues, identifying relevant according to the drawing process dimension and a reasonable selection of machine tools and cutting tools ensure the machining requirements. Secondly, according to promote green and comparison of production costs and processing programmes, work out reasonable and feasible to promote the machining process course. Finally, according to workpiece processing requirements, refer to the fixture design manual and relevant information, using design methods, development of fixture design programme, designed to save time can save resources and ensure the quality of the fixture. Main contents of fixture design is to promote the special fixture for drilling and teacher consultations, decided to design the 7th process of the fixture. Drill M8 bottom diameter of 6.6, and M8 hole drilling jig. Fixtures using φ 50 and φ35 two position using M14 and clamps t
