Abstract First of all understand that their task is to design Huqian fixed clamp on drilling holes through the painting Parts understanding of parts of the structure and working principle, and the corresponding process of analysis. Through investigation, to ask the Electrical and Mechanical Plant, and asked the teacher, refine its process line, and the preparation of the corresponding point of order, writing of the card, the process has a preliminary understanding. Then start drilling fixture design, determine positioning programme, clamping, and the mapping of the draft fixture of the assembly to determine the fixture parts map, pleted the preparation of brochures. Through this design, the machinery so that their manufacturing process with understanding, and CAD mapping software reached the level of proficiency and cultivate their own analysis, problem-solving abilities. 充值下载即送 CAD 图纸, QQ 36396305 答辩无忧,值得下载! 目录 1 、工艺分析................................................................................................................................................................ 1 结构和工作原理.........................................................................................
