摘  要
机械工业是一个国家的重要产业，机械工业的发展无时不刻都在影响着国家经济的发展，人类的进步离不开机械工业的发展。在全球经济发展的大环境下，中国各个行业被其他国家的先进技术影响的同时，越来越多的外国企业和品牌传播到中国已经成为现实。在新的市场需求的推动下，对大型四边形滚动机器人进行改良和优化是当务之急。有大型机器人生产制造企业对设备的安全指标的有着一定生产的严格要求。在生产设备的企业，充分考虑到在设备运行中可能出现的问题，从而减少噪声污染引起的振动或不当操作设备的现象等。国内大型四边形滚动机器人设备的研发及制造要与全球号召的高效经济、安全稳定主题保持一致。大型四边形滚动机器人的发展与人类社会的进步和科学技术的水平密切相关。
本毕业设计的目标是设计一种大型四边形滚动机构，该机构尺寸为大型，利用人体操作实现机构运动的控制。采用四杆机构作为设计基础，通过机构设计与仿真设计实现滚动功能。

ABSTRACT
The environment of global economic development, China industries affected by other countries advanced technology at the same time, foreign enterprises and brand spread to more and more Chinese has become an opportunity. Cap pressing machine in industry through a variety of ways have been working with the relevant technology, and constantly improve their own strength and core competitiveness, and narrow the gap with developed countries. In the new market demand, update the sleeve pressing machine is a pressing matter of the moment. The production of pipe pressing machine equipment manufacturing enterprises to fully tap the potential of the market, vigorously develop the sleeves of large low cost pressing special machinery and equipment, plays a positive role in the evolution of automatic assembly, the assembly of mechanical equipment. There is a large pipe equipment on equipment safety index has strict requirements of production. In the production equipment of enterprises, give full consideration to the possible problems in the operation of the equipment, so as to reduce the noise pollution caused by vibration or improper operation of equipment phenomenon. and manufacturing of domestic pipe pressing equipment with global appeal, economic, security and stability of the theme consistent. Increase R & D and production pipe pressing equipment of new energy saving, efficient sleeve pressing machine is the trend of development of the industry.
Recently, the use of machinery industry, bearing and shaft sleeve shaft were investigated, found that the shaft, bearings and bushings in the machinery industry is one of the key parts. Come very naturally in the assembly of the installation is also very simple. In the installation if the use of artificial pressure with not only the labor intensity is too large and the size of each other is not easy to ensure the shaft, bearing and shaft sleeve, so the design of a special press be imperative.
