文档介绍：常州机电职业技术学院毕业设计(论文) 作者: 学号: 系部: 专业: 题目: 轴承盖零件加工工艺及夹具设计校内指导教师: 企业指导教师评阅者:年月 I 毕业设计(论文)中文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 II 毕业设计(论文)英文摘要 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 III 目录 1绪论·········································································································· 1 2加工工艺规程设计························································································· 2 零件的分析······················································································ 2 零件的作用·············
