回转盘加工工艺及夹具设计-工装规程含开题及2张CAD图+说明书
廻转盘加工工艺和工装规程设计 摘要:本次设计是对廻转盘加工工艺工装的规程设计,首先要明白机械加工工艺过程就是用切削的方法改变毛坯的形状、尺寸和材料的物理机械性质,使其成为具有所需要的一定精度、粗糙度等的零件。为了能具体确切的说明过程,使工件能按照零件图的技术要求加工出来,就得制定复杂的机械加工工艺规程来作为生产的指导性技术文件,学习研究制定机械加工工艺规程的意义与作用就是本课题研究目的。在整个设计过程中,我们将学习到更多的知识。 我们必须仔细了解零件结构,从工艺上认真分析零件图,培养我们独立识图的能力,增强我们对零件图的认识和了解。通过对零件图的绘制,能增强我们的绘图能力和运用AutoCAD软件的能力。 制订工艺规程、确定加工余量、工艺尺寸的计算,在整个设计中也是非常重要的,通过这些设计,不仅让我们更为全面地了解零件的加工过程、加工尺寸的确定,而且让我们知道工艺路线和加工余量的确定,必须与工厂实际的机床相适应。 对夹具的设计:我们必须要了解夹具的作用,然后根据定位、夹紧、对刀等方面进行总体的设计。这是对以前学习过的知识的复习,也是以后工作的一个铺垫。 关键字:廻转盘工艺工装加工夹具 The Desig
