抓料机械手机构设计摘要本课题设计的为抓料机械手。工业机械手是工业生产的必然产物，它是一种模仿人体上肢的部分功能，按照预定要求输送工件或握持工具进行操作的自动化技术设备，对实现工业生产自动化，推动工业生产的进一步发展起着重要作用。因而具有强大的生命力受到人们的广泛重视和欢迎。实践证明，工业机械手可以代替人手的繁重劳动，显著减轻工人的劳动强度，改善劳动条件，提高劳动生产率和自动化水平。工业生产中经常出现的笨重工件的搬运和长期频繁、单调的操作，采用机械手是有效的。本设计拟开发的上料机械手可在空间抓放物体，动作灵活多样，可代替人工在高温和危险的作业区进行作业，可抓取重量较大的工件此外，它能在高温、低温、深水、宇宙、放射性和其他有毒、污染环境条件下进行操作，更显示其优越性，有着广阔的发展前途。本课题通过应用AutoCAD等技术对机械手进行结构设计和液压传动原理设计，它能实行自动上料运动，自动搬运棒料。机械手的运动速度是按着满足生产率的要求来设定。关键字机械手，AutoCAD ,自动化。Manipulator grasping mechanism designAbstractThis paper designed for robot grasping the material . Industrial robot is the inevitable product of industrial production, which is a part of human upper limb function mimic conveying the workpiece gripping tools or equipment operation automation technology predetermined requirements of industrial automation , and promote the further development of industrial production plays important role. Which has a strong vitality by people widely valued and welcomed . Practice has proved that industrial robots can replace heavy manual labor , and significantly reduce labor intensity and improve working conditions , improve labor productivity and automation levels. Frequent handling and long term industrial production often bulky workpiece monotonic operation, using the robot to be effective . The design of the proposed development on the feeding robot can pick and place objects in space , flexible action , instead of doing so at high temperatures and can be dangerous operation area , you can grab a greater weight of the workpiece addition, it in heat, cold, deep water , operating under the universe , radioactive and other toxic pollution environmental conditions , but also demonstrate its superiority , has a broad development prospects.This topic through the application of technologies such as AutoCAD manipulator structural design principles of design and hydraulic transmission , it can implement automatic feeding movement , automatic handling bar . Is the velocity of the robot according to the se
