I镇江高专 ZHENJIANG COLLEGE 毕业设计(论文) 座子加工工艺和夹具设计【钻+铣】【2副】 Transposon processing technology and fixture design 系名: (四号宋体) 专业班级: (四号宋体) 学生姓名: (四号宋体) 学号: (四号宋体) 指导教师姓名: (四号宋体) 指导教师职称: (四号宋体) 年月摘要 II 摘要在工艺设计中要首先对零件进行分析,了解零件的工艺再设计出毛坯的结构,并选择好零件的加工基准,设计出零件的工艺路线;接着对零件各个工步的工序进行尺寸计算,关键是决定出各个工序的工艺装备及切削用量;然后进行专用夹具的设计, 选择设计出夹具的各个组成部件,如定位元件、夹紧元件、引导元件、夹具体与机床的连接部件以及其它部件;计算出夹具定位时产生的定位误差,分析夹具结构的合理性与不足之处,并在以后设计中注意改进。关键词: 工艺,工序,切削用量,夹紧,定位,误差 Abstract III Abstract In the process of design should first of all parts to analyze, understand parts of the process and then design a blank structure, and choose the good parts of the machining datum, designs the process routes of the parts; then the parts each step process dimension calculation, the key is to determine the process equipment and cutting the amount of each working procedure design; then a special fixture, fixture for the ponents ofa design, such as the connecting part positioning device, clamping element, a guide element, clamp and the machine tool and ponents; the positioning error caused calculate fixture when positioning, analysis of the rationality and deficiency of fixture structure, pay attention to improving and will design in. Keywords: process, process, cutting, clamping, positioning 目录 IV 目录摘要······················································································· II Abstract ·················································································· III 第1章绪论············································································· 1 第2章加工工艺规程设计··························································· 2 零件的分析················································································· 2 零件的作用··········································································· 2 零件的工艺分析····································································· 3 座子零件加工的主要问题和工艺过程设计所应采取的相应措施·············· 3 孔和平面的加工顺序······························································· 3
