1、湖南工业大学本科毕业设计(论文)摘 要 首先减速器箱体进行基本的结构和工艺分析:一个优秀的结构不但要达到设计要求,还要有优秀的机械加工工艺性,也就是加工的可能性。而设计和工艺是密切相关、相辅相成的。设计者最应思考的是加工工艺问题,而工艺师则应思考使其从工艺上让设计的要求得到保证。接下来,按照要求确定箱体的毛坯,要求是中批量的生产,所以选择金属行浇铸。然后,按照要求的技术参数进行系统的分析各要求加工的面及孔的加工方法,确定粗精基准,接下来,拟订加工路线,这其中要考虑到如何让工序的组合合理,和如何合理划分阶段,同时要对方案进行相互比较。接着就是要精确地保证毛坯的尺寸以及偏差计算不出差错,还有要对各
2、工艺步骤进行合符要求的机动时间的计算和对各工序的辅助时间的统一的安排。夹具的设计,就是为了使得劳动生产率得到提升,使得加工质量得到保证,使劳动强度得到减缓。根据任务要求,这次应需设计镗、两孔的专用加工夹具。夹具将用于卧式镗床,刀具分别为麻花钻、扩孔钻、铰刀。关键词:工艺,工序,专用夹具I湖南工业大学本科毕业设计(论文)ABSTRACT First, carrying out basic machine structure and process analysis to the decelerator: a good structure is not only to meet the desig
