毕 业 设 计 设计题目：盘类轴向多孔成组 钻模设计 系 别: 专 业: 班 级: 姓 名: 学 号: 设计小组: 指导教师: 完成时间: 1 摘要 能通过运用机械制造工艺学课程中的基本理论以及在生产实习中学到实践知识，正确的解决一个零件在加工过程中的定位.夹紧以及工艺路线安排.工艺尺寸确定等问题，保证零件的加工质量 学会使用图表资料以及手册，掌握与本本设计有关的各种资料的名称，出处，能够做到熟练运用。因此，它在我们的大学生活中占有重要的地位。就我个人而言，我希望能通过这次课程设计对自己未来从事的工作进行一次适应性训练，从中锻炼自己分析问题，解决问题的能力，为今后参加工作打下一个良好的基础。由于能力有限，设计当中可能会有不足之处，恳请各位老师给予批评指正。 Abstract：Can through the utilization machine manufacture technology curriculum in elementary theory as well as in the productive practice middle school to the practice knowledge, a correct solution components in processing process localization. Clamp as well as craft route arrangement. Questions and so on craft size determination, guarantee components processing quality The academic society uses the graph data as well as the handbook, grasps designs the related each kind of material with the notebook the name, the source, can achieve the skilled utilization. Therefore, it holds the important status in ours university life. To my own opinion, I hoped that can the work which will be engaged to own future carry on an adaptability training through this curriculum project, will exercise itself to analyze the question, will solve the question ability, will start the work for the present to build a good foundation. Because ability is limited, middle the design will possibly have the deficiency, will request earnestly fellow teachers to give the criticism to point out mistakes. 2 前 言 随着科学技术的迅猛发展，市场需求的变化多端及商品竞争的日益激烈，使机械产品更新换代的周期愈来愈短，多品种、小批量生产的比例愈来愈高。为了适用这种形势的需要出现了各种新型夹具。 　　现代机床夹具的发展方向主要表现在精密化、高效化、柔性化等方面。下面介绍几种现代机床夹具。 一、可调夹具 　　可调夹具分为通用可调夹具和成组夹具(也称专用可调夹具)两类。它们共同的特点是，只要更换或调整个别定位、夹紧或导向元件，即可用于多种零件的加工，从而使多种零件的单件小批生产变为一组零件在同一夹具上的“成批生产”。产品更新换代后，只要属于同一类型的零件就仍能在此夹具上加工。由于可调夹具具有较强的适应性和良好的继承性，所以使用可调夹具可大量减少专用夹具的数量，缩短生产准
