| 摘要: 当今世界，机床工业对任何国家来说都是其基石的一个重要组成部分。随着经济的快速发展，传统的制造业已经难以满足人们的生产生活需求，因此，具有自动化线的制造业逐渐出现在人们的生产生活中。自动化生产线代替了人手的繁重劳动，减轻了劳动强度，提高了生产效率。自动化生产方式在现代制造业中的使用是非常高效的，而本文就此设计了一种自动上下料机构上料及料台结构设计。23578 本文首先介绍了数控机床的概念，然后介绍了自动上下料上料机构的概念，接着介绍了上料机械手的组成和分类，机械手的自由度和座标形式，驱动方式等内容，确定了机械手的座标形式，自由度及驱动方案。之后分别设计了机械手的夹持式手部结构，机械手的手腕结构手腕回转结构，机械手腰部的升降结构及回转结构，并对其各部分的驱动液压缸做了计算确定了液压缸的内径，外径，及活塞杆的直径。最后介绍了料台的结构设计和驱动方式等。 毕业论文关键词：上料机械手；自由度；结构设计；三文造型 CNC lathe autotransmitting mechanism of feeding and discharging platformstructure design Abstract：With the needs of the development of industrial automation , robots are more and more important in industrial applications .Industrial robots can replace manpower heavy labor , significantly reduced labor intensity of workers, improve labor productivity and the level of automation .It solves the handling of heavy artifacts often appears in industrial production and frequent, monotonous operation for a long time, but also improves the production speed of workpiece, so the use of the manipulator is very efficient, and to a feeding manipulator is designed in this paper. This paper first introduces the concept of industrial robots, composition and classification of the manipulator, the degrees of freedom of the manipulator and the coordinates form, drive mode, etc.Then according to the technology of the manipulator overall design parameters on the manipulator was carried out, determine the coordinates of the manipulator type and degree of freedom and drive solutions.After that the holding type hand structure of the manipulator is designed, the structure of manipulator wrist wrist rotation structure, lifting structure and the structure of rotary manipulator waist, and the driving hydraulic cylinder of each part to do the calculation to determine the hydraulic cylinder inner diameter, outer diameter, and the diameter of the piston rod. Finally made related to the hydraulic system is introduced and the hydraulic system to do the simple design of the manipulator.
