数控车床装配设计(含CAD图)(任务书,文献综述,设计说明书11000字,CAD图纸2张)
摘 要
 自从1946年世界上首次电子计算机制造以来,这说明人们制造了工具,能增加和替换脑力。它和工具,人类在农业和工业社会,有了质的飞跃,为人类进入奠定了基础信息社会。在1952年,计算机技术应用于机器,第一个数控机床的诞生在美国。从那时起,近年来传统的机床,数控机床公司逐年增加,并被应用在大中型企业中,有了质量的变化。近半个世纪以来,数控系统经历了两个阶段和六代的发展。在中小企业甚至个人企业也普遍开始使用。在这些数控机床,除了少量的机床在FMS模式集成,主要是在独立的运行状态,和相当部分的使用效率不高,落后的管理模式。近年来,中国的出口增长的大型数控机床是数控车床、数控磨床、数控加工专用机床,数控剪板机,数控折弯,折弯机,数控压铸机、通用机床。
   在车床主传动系统的毕业设计中，使学生建立不错的的规划和了解车床主传动系统设计的一般方法。
 巩固和加深所学理论知识，加深知识储备，运用所学知识剖析和处理设计工作中的实际问题。

Abstract
  1946 birth of the world's first electronic computer, which suggests that human created can be enhanced and part instead of the mental work tools. It with humans in agriculture, industrial society to create those is only a means of enhancing physical labor, compared to a qualitative leap, which laid a foundation for human into the information society. Six years later, in 1952, the computer technology application in machine tools, was born in the United States the first CNC machine tool. Since then, traditional machine tools produced in recent years, our country enterprise of nc machine tools share rise year by year, in large and medium-sized enterprises have more use, a qualitative change. Nearly half a century, the CNC system has experienced two stages and the development of six generations. Also common in small and medium-sized enterprises and individual enterprises begin to use. In the nc machine tools, in addition to a small amount of machine tools used in FMS model integration, mostly in single machine running state, and some in the efficiency is not high, management way backward state. In recent years, China's exports was bigger nc machine tool with CNC lathe, CNC grinding machine, numerical control special machine tools, CNC bending machine, CNC shearing machine, CNC forming die casting machine, such as the common machine tools have a drilling machine, sawing machine, slotting machine, broaching machine, combination 
machine tools, hydraulic press. 
Through the lathe main drive system of curriculum design, causes the student to set up the correct design ideas and master the basic method of lathe main transmission system design.
Consolidate and deepen the theory knowledge, the expanded aspect of knowledge, and apply what they have learned the theory analysis and solve specific problems in the design work;
By machinery and equipment course design, causes the student to the structure of the main transmission mechanism in forming lathe, lathe parts design, all kinds of scheme design, calculation, write technical documents and the expression of design ideas and so on, to get basic training comprehensive;
Be familiar with the relevant standards and manuals and the use of the resources, to foster a preliminary structural analysis and the ability to structure design and calculation.

Keywords: main drive system, transmission design, dynamic design
