Abstract:
In order to realize automatic polishing of propeller, dynamic analysis and topological optimization of a propeller polishing machine tool were studied. The machine adopts the design of series clamping robot and auxiliary support arm to cooperate, which retains the advantages of high flexibility of series robot, while the addition of auxiliary support arm improves the stiffness of the clamping robot. The spatial coordinate system of the clamping robot of the propeller polishing machine tool was established. The position of the clamping robot in the propeller polishing machine tool was determined using the D-H method, and its working space was calculated using the Montecarlo method. The dynamics analysis of the clamping robot showed that the torque of joint 2 and joint 3 was too large, and the topology optimization of the upper and lower arms of the clamping robot was carried out. According to the topological optimization results, the model of the upper and lower arms was improved, and the structural optimization scheme of the propeller polishing machine tool was finally obtained. The results show that the maximum torque of joint 1, joint 2 and joint 3 is reduced by 13%, 19.6% and 14.8%, respectively.
