Fluidsim-based Robot Gripper Design And Control

Today, many domestic factory production lines, CNC machine loading and unloading the work piece are still manipulated manually and intensive labor, production efficiency is low. In order to improve the efficiency of the production process, reduce costs, turn production line into a flexible manufacturing system and meet the needs of modern automated large-scale production, this paper will replace the manual handling with robot, and thus improve labor productivity through the use of robot technology.The manipulator is mainly to implement automation which related to CNC machining equipment, hand combined to form production lines. It is designed to take full account of the robot work environment and process specific requirements. To meet process requirements, simplify the structure and use the standardized, modular components common element as far as possible.Hydraulic control system is the integrated industrial automation system which composed of mechanical, electrical, hydraulic and computer control devices. It is an important part in mechanical transmission and is often used in a variety of automated production lines and equipments. This design uses the most popular pneumatic control simulation the FluidSIM software developed by the German FESTO, it integrates CAD features and simulation capabilities together and can simulate the circuit diagram component-based physical model.The design of the industrial robot is a kind of coordinate hydraulic drive manipulator. With a telescopic arm, lifting, rotating the wrist three degrees of freedom, the corresponding body contains arm stretching, arm lifting mechanism and the arm rotating mechanism. All parts are driven and controlled by the hydraulic cylinder or hydraulic motor.This paper mainly researches robot gripper, telescopic boom, hydraulic system and PLC control program. The contents include telescopic holder and the determination of the overall program, hydraulic and electric drive systems design, electrical and hydraulic cylinder selection and calculation, the overall structural design, the stress and strength analysis of main body parts such as hydraulic telescopic rod and guide plate.
