主轴箱操纵机构及轴的设计.doc

摘 要 此次毕业设计要求综合的运用机械制图、机械设计、机械原理、机械制造技术、金属切削机床设计等相关知识对CA6140型卧式车床进行了传动设计，主要对其主轴箱的结构和传动原理进行深入的了解。CA6140车床是我国设计制造的典型的卧式车床，在我国机械制造类行业中使用极为广泛。近些年，虽然随着电子计算机的发展，数控技术和数控机床得到的较大的发展，但通过对普通车床的研究和设计，可以开阔我们的视野，增强我们的实践经验，加强我们自己动手的工作能力，巩固所学知识，在我们马上要走上工作岗位之际，对提高我们的专业素质有很大的帮助。 本次毕业设计的研究内容、方法、成果： 1、通过绘制车床主轴箱操纵机构的装配图，进一步深入的了解了主轴箱的结构和其传动原理； 2、通过运用机械原理和机械设计等知识对车床进给箱中的轴进行设计和校核； 3、最后运用机械制图知识绘出CA6140型卧式车床主轴箱操纵机构，并运用AutoCAD制图软件绘制进给箱中的014轴，进一步熟练了CAD的使用。 关键词：CA6140型车床；主轴箱；传动系统；轴的设计；轴的绘制； ABSTRACT The integrated design uses a mechanical drawing, mechanical design, mechanical principles, machinery manufacturing technology, Metal Cutting Machine design knowledge to CA6140 horizontal lathe design of the drive, Headstock mainly on the structure and box drive principle in-depth understanding. CA6140 lathe is the design and manufacture of a typical horizontal lathe. Chinas machinery manufacturing industries, is widely used. In recent years, although the development of electronic computers, technology and CNC machine tool CNC is the larger development, But through Lathe of research and design, broadening our horizons, enhance our practical experience, strengthen our own hands the ability to consolidate knowledge, we all got to go to work when to improve the professional quality of our great help. The graduation of the study design, methods, results : 1. Drawing spindle lathes me through manipulation of the assembly, further in-depth understanding of the structure of the spindle box and its drive principle 2. Through the use of mechanical principles and mechanical design knowledge to design and check the shaft in lathe . 3. Finally the use of AutoCAD software rendering the machine spindle and operating mechanism , and the use of CAD to render the 014 shaft in lathe;Further skilled in the use of CAD .
