设计简介
摘 要
首先了解到自己的设计任务是在虎钳固定钳身上钻削
孔，通过画零件图了解零件的结构和工作原理，并进行相应的工艺性分析。通过查资料、到机电总厂请教，并问老师，不断修正自己的工艺路线，并编制相应的工艺规程，写工艺卡片，对加工过程有了初步了解。接着开始钻床夹具的设计，确定定位方案，夹紧机构，并绘制夹具的装配草图，确定夹具的零件图，并完成说明书的编写。
通过这次设计，使自己对机械制造工艺有了了解，并对CAD制图软件达到了熟练的程度，培养了自己分析问题、解决问题的能力。
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, and completed 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.
