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, 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 IV 目录摘要........................................................................................................................................
