数控车床自动上下料机构换料结构设计及CAD图纸
本次设计对机械手的重要部分进行了详细的介绍，包括手爪、腕部、手臂、腰部、机身等。最终确定机械手的设计采用圆柱坐标式。本次设计手爪的张合，机座和腕部的旋转，手臂和腰部的伸缩运动都是采用气缸驱动。
本次设计是数控车床自动上下料机构的结构设计，所以本次设计最终的效果是通过上下料机构实现对供料台上毛培圆柱毛培料的抓取及传送，抓取及传送的过程要求快速、准确、灵活。另外，考虑到经济性，机械手要尽量做到体积小，重量轻，文护方便等优点。

ABSTRACT
In industry fast development in the world today, the traditional manufacturing industry has been difficult to meet the demand of people, automated production line has become a important part of modern manufacturing. Manipulator with the continuous development of science and technology, more and more applied in the field of manufacturing, it can be in accordance with the has set a good program to grab parts, handling, etc. in order to protect the personal safety,Manipulator also can replace human in dangerous environment.the other robots can also help people deal with repetitive manual labor, Make the production efficiency is greatly increased , and the paper designs a kind of automatic up-down material organization structure design and loading area.
Detailed introduction of the design of the manipulator is an important part, including gripper, wrist, arm, waist, body.The design of the manipulator is finally determined by using cylindrical coordinates.The driving part includes cylinder drive, fingernail, arm, waist movement, rotation frame and wrist.
This design is the numerical control lathe automatic up-down material organization structure design, so the design of the final effect is through the institution of feed up and down the stage gross-pui cylindrical gross-pui material fetching and transmission, fetching and transfer process for quick, accurate and flexible. In addition, considering the economy, the manipulator to try to be small size, light weight, convenient maintenance.
Keywords: manipulator, structure design, cylinder, 2D graphics
