箱体钻、扩孔双面移动工作台式组合机床右多轴箱设计 题目:箱体钻、扩孔双面移动工作台式组合机床右多轴箱设计 系 别: 机电系 专 业: 机械制造设计及其自动化 班 级: B080204 学 生: 申雨沛 学 号: 指导教师: 朱育权 2012年4月 箱体钻、扩孔双面移动工作台式组合机床右多轴箱设计 摘要 多轴箱是组合机床中的主要专用部件之一。通过本题目的设计可以使机械设计制造及其自动化专业学生对四年所学主要课程有一次较为全面的综合应用,得到一次近乎实战的锻炼机会。 本文介绍了箱体钻、扩孔双面移动工作台式组合机床右多轴箱设计,对其设计过程进行了详细的介绍,主要内容有:依据被加工工件孔的特点确定切削参数,根据所定参数计算其运动参数和动力参数,并对主轴的轴径、支承方式和所用的轴承等进行选型;接着选择动力箱和主箱体的型号、确定主轴和动力输入轴的位置,再根据主轴及动力输入轴的位置进行传动方案的设计、传动齿轮的确定;最后计算各传动轴、主轴的坐标,验算齿轮的中心距,设计变位齿轮,对传动轴、轴承和齿轮等重要零部件进行校核。 通过本设计使以前学过的理论知识和实践更加紧密的联系起来。同时我认识到知识是无穷尽的,在今后的生活中,我应该把握每一次的机会充实自己。 关键词:组合机床;多轴箱;主轴;传动轴;齿轮 Cabinet drilling, reaming the double-sided mobile desktop combination machine right axle box design Abstract Multi-axle box is one of the specially designed components in the machine tool, Mechanical Design Manufacturing and Automation students through the design of this subject can be a four-year main courses have a more comprehensive integrated application, once almost like a real opportunity to exercise. In this paper, propose the design of right multi-axle box on combination machine that with a boring, expansion two-sided horizontal of the two mobile working platform ,and illustrate its design process in details. The main contents include: determine the cutting parameters based on the characteristics of the workpiece hole. caculate their movement parameters and dynamic parameters according to parameters set. And select the main shaft, supporting methods and the use of bearings, etc; then choose the model of driving box and spindle box, determine the location of spindle and the drive shaft, and then design the transmission plan as well as confirm the transmission gear according to the location of spindle and the driving shaft. finally, calculate coordinates of every transmission axis and spindle, check the central distance of gear, design change gear and check drive shaft, bear
