文档介绍：CA6140 车床后托架加工工艺及夹具设计学生姓名: 学生学号: 院(系) : 年级专业: 指导教师: 2012 年 12月攀枝花学院本科毕业设计(论文) 摘要 I 摘要机械加工工艺是实现产品设计,保证产品质量,节约能源,降低消耗的重要手段。本课题研究 CA6140 车床后托架加工工艺规程。首先通过对零件图的分析,了解工件的结构形式,明确了具体的技术要求,从而对工件各组成表面选择合适的加工方法。再拟订较为合理的工艺规程,充分体现质量、生产率和经济性的统一。机床夹具设计是工艺装备设计中的一个重要组成部分,在整个机械加工过程中,夹具除了夹紧、固定被加工零件外,还要求保证加工零件的位置精度、提高加工生产率。本课题在设计的过程当中,深入生产实际,进行调查研究,吸取国内外先进技术,制定出合理的设计方案,在进行具体设计。关键词产品设计,后托架,加工工艺,夹具攀枝花学院本科毕业设计(论文) ABSTRACT II A BSTRACT He machine-finishing craft realizes the product design, guaranteed the product quality, saves the energy, reduces the consumption the important method. After this topic studies the CA6140 lathe the bracket processing technological process. First through to the detail drawing analysis, understood the work piece the structural style, has been clear about the concrete specification, thus to work piece position surface choice appropriate processing method. Again drafts the more reasonable technological process, fully manifests the quality, the productivity and the efficient unification .E ngine bed jig design is ina craft equipment design important constituent, in the entire machine-finishing process, the jig except clamps, fixes is processed outside ponents, but also requests guarantee ponents position precision, enhancement processing productivity .T his topic in the middle of the design process, rates the production reality, conducts the investigation and study, absorbs the domestic and foreign advanced technologies, formulates the reasonable design proposal, is carrying on the concrete design . Keywords shift the product design , latter bracket , processing craft , jig 攀枝花学院本科毕业设计(论文) CA6140 车床后托架加工工艺设计 1 目录摘要…………………………………………………………………………………………Ⅰ ABSTRACT ……………………………………………………………………………………Ⅱ 1 CA6140 车床后托架的加工工艺设计..................................................................... 3 CA6140 车床后托架的结构特点和技术要求.......................................................... 3 CA6140 车床后托架的材料、毛坯和热处理................................................................... 3
