1. Choosing a smaller motion inertia standard can improve the motion stability of the welding manipulator and improve the dynamic characteristics of the welding manipulator.
2. In the welding manipulator scheme, its rigidity is more important than its strength. In order to make the rigidity greater, it is necessary to reasonably screen the cross-sectional shape and standard of the parts, stroke support rigidity and contact rigidity, and reasonably organize the force and moment acting on the arm to minimize Bending deformation of parts.
3. For the working space to meet the relevant requirements, specification optimization selection arm specifications help to improve the rigidity of the welding manipulator, thereby further reducing the motion inertia.
4. Welding manipulators must have screening specifications for strength data. Welding manipulators are loaded sequentially from the structure, and the screening specifications for high-strength data should reduce the quality of parts.
