支架工艺及铣Φ14mm和Φ22mm孔端面夹具设计

 支架工艺及铣Φ14mm和Φ22mm孔端面夹具设计   

一、选题简介、意义
. 随着社会发展的需要,机械加工作为一个传统而富有活力的行业,在现经济时代,其行业发生着结构性变化,工艺工装的设计与改良已成为亿鼎博手机版生存和发展的必要条件,工艺工装的设计与改良直接影响加工产品的质量与性能。
本次设计是在学完了大学的全部基础课,专业课之后进行的;是我们在进行毕业实习之前对所学各课程的一次深入的综合性设计,要求我们运用先前所学的知识进行工艺与夹具的设计,通过这次毕业设计对自己未来将从事的工作进行了一次适应性训练,从中锻炼自己查阅相关资料、分析问题、解决问题的能力,能够更深入理解课本知识,对设计中涉及到的机械制造工艺规程,工艺方案论证,机械加工余量计算,工艺尺寸的确定,编写技术文件及专用夹具的设计与计算等各个方面有了更好的掌握,并能够更好的应用理论知识,为以后更好地胜任工作岗位打好基础,同时也是一次理论与实际相结合的训练。
 二、研究的主要内容,拟解决的主要问题
    根据毕业设计任务要求,主要研究了支架工艺及铣Φ14mm和Φ22mm孔夹具设计机械加工工艺过程的编制。首先介绍了支架工艺及铣Φ14mm和Φ22mm孔夹具设计作用和工艺分析,其次确定了毛坯尺寸,绘制了生产工件的毛坯图和零件图,然后进行了工艺规程设计,并附有生产工艺过程卡,机械加工工艺卡以及机械加工工艺卡,最后进行对铣下平面夹具设计,指出了工件的定位、夹紧、导向及其他元件或装置的结构形式,并对加工工序进行了精度校核。
通过这次设计,能够综合运用机械专业相关理论知识,分析和解决机械加工工艺问题,初步具备设计中等复杂程度零件的工艺规程的能力;能根据被加工零件的技术要求,运用夹具设计的基本原理和方法,学会拟定夹具设计方案,完善夹具结构设计,初步具备设计保证加工质量的高效、省力、经济合理的专用夹具的能力。
三、研究(工作)步骤、方法及措施(思路)
此次设计是对支架工艺及铣Φ14mm和Φ22mm孔夹具设计机械加工工艺过程的编制及铣下平面夹具设计,其零件为铸件,具有体积大,零件结构复杂的特点,由于面比孔易加工,在制定工艺规程时,就先加工面,再以面为基准来加工其它,其中各工序夹具都采用专用夹具,其机构设计简单,方便且能满足要求。其内容及具体要求如下:
(1)分析研究被加工零件,画出零件图。
(2)确定生产类型和工艺特征。
(3)选择毛坯种类及制造方法,确定毛坯尺寸,绘制毛坯图。
(4)选择加工方法,拟定工艺路线。
(5)进行工序设计和工艺计算。
(6)画出工序简图,填写工艺文件。
(7)设计专用夹具。
(8)编写毕业设计说明书。
