Abstract
This subject is designed for six degrees of freedom welding robot and numerical controlled welding positioner. Six degrees of freedom welding robot can achieve a range of the end of the crew can be realized will be required, and in spirit. The robot consisting of two degrees of freedom pudgy forearms part of a pudgy forearms, with the pitch of the wrist, arm and a large part of a degree of freedom, we can carry big arm of the pitch. Determine the design robot welding robot transmission programme, joint type of robot six degrees of freedom parameters and power parameter, the motor of the select and detailed design of structure. Numerical controlled welding positioner is used to the length shorter, the circling of the moment is 500nm, payload 2000kg, drived with two positioners. The design has determined the numerical controlled welding positioner type, the powered and actuation device, the retarding mechanism and the detailed design of the numerical controlled welding positioner.
