I XX 大学毕业设计论文 Y 轴轴承座加工工艺及铣 A 面夹具设计所在学院专业班级姓名学号指导老师年月日沈阳工学院毕业论文 II 摘要 Y 轴轴承座零件加工工艺及钻床夹具设计是包括零件加工的工艺设计、工序设计以及专用夹具的设计三部分。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,误差全套图纸,加 153893706 沈阳工学院毕业论文 III Abstract Y bearing seat parts processing technology and design of drilling jig is designed including machiningprocess design process design and fixture three. In the process of design should first understand the analysis of parts, parts of the process to design a blank structure, and choose the ponents the processing datum, designs the process routes of the parts; then the parts of each labor step process size calculation, is the key to decide the craft equipment and the cutting process of the various design parameters; then the special fixture, the fixture selection for the ponents of the design, such as connecting parts positioning device, clamping element, guiding element, clamp and machine tools and ponents; positioning error is calculated when the fixture, analysis the rationality and ing of fixture structure, improve and design in later. Keywords: process, process, cutting, clamping, positioning, error 沈阳工学院毕业论文 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
