自动上料机械手设计

AbstractWith the continuous progress of the society and the continuous development of science andtechnology level,people demand more and more time,so in large-scale manufacturing,theproduction of products by manpower has been insufficient to support the operation of theenterprise,in order to improve work efficiency,and ensure the quality of the product,theenterprise must realize mechanical automation as soon as possible,and it has become theprimary problem that needs to be focused at the moment.With the decrease of human labor,industrial robots have replaced them on the automatic production lines,and have beenrecognized and adopted by many enterprises.We can see that the national industrial automationlevel has a direct impact on manufacturing technology level and applied degree of the industrialrobot,In some special environments,such as high temperature and high pressure,which peoplecannot work,industrial robots have played a role,in the case of ensuring the quality of products,it can help human beings overcome the difficulties that cannot be accomplished under specialcircumstances,and at the same time free their hands to further improve labor productivity.At thepresent stage,industrial robots are mainly responsible for tasks such as painting,welding andhandling,which are either highly repetitive or difficult to work,and work in the way ofdemonstration and teaching reproduction.In this paper,a three-degree-of-freedom industrial robot is designed.Its main function is totransport materials.Its overall design is made up of the following four parts:the first is theoverall design;the second is the composition and application of industrial manipulator;the thirdis to design the manipulator hydraulic system;and the last one is to design the control system.We drive of the manipulator in the drive system,in order to guarantee the precision ofpositioning,at the same time to ensure the operation is simple,the overall process is notcomplicated,and easy to control,so selecting for the hydraulic cylinder to operate.The authoralso analyzed and calculated the control system and the hydraulic system,in order to furtherdesign the control system of the manipulator,PLC is the core.The control system is controlledby PLC,which coincides with the general direction of designing industrial control system.Moreover,the design of hardware circuit and manipulator control program is carried out on thebasis of process flow and design requirements of the manipulator.Key words:industrial machinery;hydraulic system;computer-assisted;dedicated device
