摘要世界制造业转移,中国正在逐步成为世界加工厂。
美国、德国、韩国等国家已经进入工业化发展的高技术密集时代与微电子时代,钢铁、机械、化工等重工业正逐渐向发展中国家转移。
我国目前经济发展已经过了发展初期,正处于重化工业发展中期。
未来10年将是中国机械行业发展最佳时期。
美国、德国的重化工业发展期延续了18年以上,美国、德国、韩国四国重化工业发展期平均延续了12年,我们估计中国的重化工业发展期将至少延续10年,直到2015年。
因此,在未来10年中,随着中国重化工业进程的推进,中国企业规模、产品技术、质量等都将得到大幅提升,国产机械产品国际竞争力增强,逐步替代进口,并加速出口。
目前,机械行业中部分子行业如船舶、铁路、集装箱及集装箱起重机制造等已经受益于国际间的产业转移,并将持续受益;电站设备、工程机械、床等将受益于产业转移,加快出口进程关键词 : 数控工业化发展机床ABSTRACTMove of world manufacturing industry, China is becoming the world factory. The United States, Germany, Korea and other countries have entered the high technology industrialization development intensive era and the era of microelectronics, steel, machinery, chemicals and other heavy industry is gradually transferred to developing countries. Our current economic development has been the early stage of development, the development of heavy industry is in the middle.The next 10 years will be the best period in China machinery industry development. The United States, Germany's heavy industry development has continued for more than 18 years, the United States, Germany, South Korea four heavy industry development average lasted 12 years, we estimate that China's heavy industry development will continue at least 10 years, until 2015. Therefore, in the next 10 years, along with the advancement of heavy industry of China, Chinese enterprise scale, product technology, quality and so will be significantly improved, the international competitiveness of domestic machinery products increased, gradually replace the imported, and accelerated export. At present, the central molecular machinery industry sectors such as shipping, railways, container and container crane manufacturing has benefited from the international industrial transfer, and will continue to benefit; power equipment, engineering machinery, such as bed will benefit from the industrial transfer, speed up the process of exportKeywords: CNC machine tool industrialization development目录ⅰ目录第一章绪论 (1)1.1 课题来源 (1)1.2 目的和意义 (1)1.3 机电一体化系统的简介 (1)1.3.1 机电传动概述 (2)1.3.2 数控加工概述 (2)1.3.3 数控加工设备 (3)1.4 国内外动态 (5)1.5 机电一体化技术的发展与展望 (7)第二章简易数控机床的结构分析 (9)2.1 数控机床的外部结构 (9)2.1.1 简易数控机床的外形 (9)2.1.2 简易数控机床的外部结构 (9)2.1.3 简易数控机床的XY轴结构 (10)2.2 数控机床内部结构分析 (11)第三章 PRO/E简介 (13)3.1 pro/e的诞生 (13)3.2 pro/e的具体操作与优点 (13)3.3 pro/e的引入 (14)第四章数控机床的机械设计 (17)4.1 零件图 (17)4.2 组装图 (20)第五章总结 (21)第六章结束语 (23)致谢 (25)参考文献 (27)第一章绪论 1第一章绪论1.1课题的来源随着各种学科的交叉发展,原来的纯机械加工已经发展为机电一体化的加工机床,现在随着各种控制技术的日趋完善,机电一体化的加工系统——数控机床已经毫无疑问成为了工业生产的主力装备。
