doi:10.3901/JME.2023.09.012

Abstract

Abstract: In order to improve the efficiency, quality and automation of weld reinforcement grinding in the process of large vessels manufacturing, the influence of the amplitude and direction of machining force on the wall-climbing robot for weld modification is discussed by using the principle of mechanics, and the conditions such as the posture of the weld cutting tool are optimized. Then, through the modeling and analysis of cutting reaction force and modification efficiency, a novel "filing-milling" weld modification technology suitable for wall-climbing robot is proposed, and the corresponding "milling-filing" cutting tools and the wall-climbing robot system are designed and developed. The experimental results show that the robot system can cut the weld reinforcement efficiently, and the machining quality is better than the relevant provisions of national and industrial standards. Moreover, the production environment has been significantly improved compared with the traditional methods.

Key words: wall-climbing robot, weld modification, mechanical analysis, cutting tool
