Abstract：

In view of the application condition of the loading and unloading machine, the conditions that the clamping mechanism should meet were studied, the necessity of constant output clamping force of clamping arm was clarified, the influences of structural parameters on the force transfer ratio and the clamping device were analyzed, and the design scheme of the clamping mechanism was determined by combining the structural characteristics of the two clamping modes. According to the trend of material friction coefficient changing with temperature, the rationality of adopting convex tooth structure for clamping claw was analyzed, and gray cast iron was defined as clamping claw material. Then, the design idea of the structural parameters of the clamping mechanism for the loading and unloading machine was studied, and the design method of the constant output clamping force for the clamping arm was described. According to the research idea of the clamping mechanism for the loading and unloading machine, the clamping device of 30 kN loading and unloading machine was calculated by the theoretical calculation, which verified the feasibility for the research results and provided a reference for the structural design and theoretical research of the clamping device for the loading and unloading machine.
