16、机械或机械制造业的产品。我们的生活离不开制造业,因此制造业是国民经济发展的重要行业,是一个国家或地区发展的重要基础及有力支柱。从某中意义上讲,机械制造水平的高低是衡量一个国家国民经济综合实力和科学技术水平的重要指标。后罗拉过桥摇臂零件的工艺规程及铣端面的夹具设计是在学完了机械制图、机械制造技术基础、机械设计、机械工程材料等进行课程设计之后的下一个教学环节。正确地解决一个零件在加工中的定位,夹紧以及工艺路线安排,工艺尺寸确定等问题,并设计出专用夹具,保证零件的加工质量。本次设计也要培养自己的自学与创新能力。因此本次设计综合性和实践性强、涉及知识面广。所以在设计中既要注意基本概念、基本理论,又要注
17、意生产实践的需要,只有将各种理论与生产实践相结合,才能很好的完成本次设计。本次设计水平有限,其中难免有缺点错误,敬请老师们批评指正。一、 零件的分析1.1 零件的作用后罗拉过桥摇臂零件作用,待查1.2 零件的工艺分析后罗拉过桥摇臂有2个加工面他们相互之间没有任何位置度要求。1:以73下端面为基准的加工面,这组加工的主要是镗47孔。2:以47孔为基准的加工面,这组加工面主要是各个孔端面及其螺纹孔。二. 工艺规程设计2.1 确定毛坯的制造形式零件材料为HT200,考虑到零件在工作过程中经常受到冲击性载荷,采用这种材料零件的强度也能保证。由于零件成批生产,而且零件的轮廓尺寸不大,选用砂型铸造,采用机
