Abstract：

Aiming at the typical types of clamping forgings, the performance requirements of clamping mechanism for forging manipulator were analyzed, and the necessity of constant force output of clamping mechanism was clarified.According to the structural characteristics of clamping mechanism for forging manipulator, the force transmission ratio of clamping mechanism was analyzed, and the key factors affecting the force transmission ratio of clamping mechanism were determined, and the determination method of structural parameters of clamping mechanism was studied.Taking the maximum radius of gyration of clamping mechanism for forging manipulator as the basis and combining with the structural parameters of clamping mechanism, a determination method of force transmission ratio of manipulator clamping mechanism was presented,which could realize the constant force output and provide a theoretical basis for the determination of force transmission ratio of the constant force output clamping mechanism.Taking the clamping mechanism for 300 kN manipulator as an example, the feasibility of research idea was verified, and the idea of improving the clamping performance of clamping mechanism was analyzed, which provided a reference for the design of constant force output clamping mechanism.
