Research on the Design and Motion Optimization of the Rotating Mechanism of the Flipping Tooling

Aiming at the problems such as low flipping efficiency and poor motion stability of the existing flipping tooling in the process of handling heavy-duty workpieces, a new rotary mechanism of the flipping tooling based on worm gear and worm drive is designed. By establishing the kinematic and dynamic models of the mechanism, the influence laws of key parameters on the flipping performance were analyzed, and the multi-objective optimization algorithm was adopted to optimize the parameters of the rotary mechanism. The simulation and experimental results show that the optimized rotary mechanism, while ensuring the flipping accuracy, increases the flipping efficiency by 23% and significantly improves the smoothness of the motion, providing an effective solution for the flipping operation of heavy-duty workpieces.
