安徽建筑工业学院 毕 业 设 计 (论 文) 专 业 机械设计制造及其自动化 班 级 04机械（1）班 学生姓名 胡 德 飞 学 号 04207040218 课 题 汽车底盘转向节弯臂工艺装备设计 指导教师 闫兴书 石静芝 2008 年 6 月 6 日 摘要 其内容包括该零件的分析，工艺方案的选定与比较，机床与切削用量的选取，时间定额的计算，夹具的定位分析与定位误差的计算，夹紧力的估算等。 根据汽车转向节弯臂零件的基本情况，以机械加工工艺工序、钻夹具定位、夹紧要求设计汽车转向节弯臂钻夹具。在设计专用钻夹具和专用钻攻丝夹具时，选择合适的机床，并且进行刀具、量具、辅具的选择。 通过对实际产品的实际设计和比较，改善汽车转向节弯臂设计过程，降低生产成本。更一步发现自身知识的不足和经验的缺乏。提高从理论到实际的升华。培养我们综合应用所学知识和技能以及解决实际工程问题和进行创造性工作的基本训练；培养学生独立工作和团队协作能力；培养学生树立正确的设计思想，掌握机械加工工艺及装备设计方法；也是对我们学习成果的一次全面考验。在设计中我们可以理论联系实际，不仅可以强化学到的理论知识，而且可以将从书本上学到知识运用于实际生产。 关键词：汽车转向节弯臂 工艺方案 时间定额 切削用量 钻夹具 Abstract Its contents, including the parts analysis, and the selection of programmes, the machine tool and cutting the amount of selection, the fixed time, the positioning of the fixture with the positioning error of calculation, such as estimates of the clamping force. According to auto parts arm of bending the basic conditions to mechanical processing operations, drilling fixture positioning, clamping vehicle designed to bend arm of drilling fixture. Fixture for drilling in the design of special drilling and tapping fixture, choose the right machine and a cutting tool, measuring tool, Des Voeux a choice. Based on the actual design and the actual products, to improve vehicle design process of bending arm, lower production costs. More step in the knowledge that their own inadequacies and the lack of experience. Increase from theory to practical sublimation. Nurture our comprehensive application of knowledge and skills, and solve practical engineering issues and creative work of basic training; training students to work independently and teamwork ability to train students establish the correct design, master processing machinery and equipment design method is to We learn the outcome of a comprehensive test. In the design,
