Optimum Design and Research of the Vertical Manipulator Arm Rotation Structure
Abstract
Aiming at the installation of prefabricated wall panels in today's assembly building, a new type of wall panel vertical machine is designed, which realizes the adjustment of the pitch position and position of the end grabbing device through the arm turnover mechanism, thus realizing the positioning and installation of prefabricated wall panels. The boom turnover mechanism belongs to the hydraulic linkage mechanism. Through the mechanical simulation analysis, it is found that the boom landing mechanism belongs to the main bearing mechanism and the driving cylinder has the largest load. Therefore, a scale optimization model is established for the boom landing mechanism to minimize the maximum load of the driving cylinder as the objective function. Based on the complex method, the optimal scale parameters of the boom turnover mechanism are obtained, and the maximum load of the driving cylinder before and after optimization is reduced by about 36%. Drive cylinder performance is significantly improved. The virtual prototype is built by Creo software and the rigid body dynamics simulation analysis is carried out. The mechanism scale optimization model is validated. Finally, the prototype development and the construction test are carried out, and the working performance of the boom turnover mechanism meets the design requirements.
