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 machining datum, designs the process routes of the parts; then the parts of 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 of the design, such as the connecting part positioning device, clamping device, a guide element, clamp and the machine tool and ponents; the positioning error generated when calculate fixture positioning, analysis of the rationality and deficiency of fixture structure, pay attention to improving and will design in. Key words: Technology, process, cutting, clamping, positioning 优秀机械毕业设计欢迎下载,学****交流加 QQ 197216396 专业机械设计解君之忧 III 目录 1 绪论............................................................................................................................................................................... 1 2 零件的分析.................................................................................................................................................................. 2 零件的形状........................................................................................................................................................... 2 零件
