Abstract
After three years of study, through this design, further understand the learned knowledge, understand the structure composition and
function of the robot, this design is cylindrical coordinate robot. The concept, composition and classification of robot are introduced
briefly. In this paper, the overall design of robot is carried out, the scheme of robot is determined, and the technical parameters of
robot are determined. At the same time, the drive torque of the rotating cylinder is calculated and the other parts of the manipulator
are also designed in detail.
The overall scheme design of the whole manipulator is mainly based on the lumbar seat mode, arm structure, actuator, transmission
system, etc., for detailed design, and the performance ability of the system is analyzed in depth during the design, and the specific
execution steps are described. At the same time, the hydraulic system and control system are demonstrated from the theoretical analysis
according to relevant reference materials. When designing the PLC control of the manipulator, set the required parameters in advance.
Finally, through the detailed analysis and design of the internal circuit of the control system, the corresponding system control
program is developed, and finally the combined production line of the manipulator, lathe and milling machine is formed.
