水下机器人（ROV）快速更换工具库可以减少ROV在水面母船的作业准备时间，提高作业效率。自动对接锁紧机构是ROV快速换装工具库的关键装置。根据ISO 13628-8（2002）标准设计了ROV与工具库的对接锁紧机构。介绍了油缸锁紧机构原理及锁紧力计算公式。通过锁紧指结构参数的优化，液压驱动力得到有效降低。
The operating efficiency of remotely operated vehicle (ROV) could be improved by replacing its tool library quickly.The butt locking mechanism of ROV tool library is the key device for the replacing operation.We design such a butt locking mechanism according to the ISO 13628-8 (2002) standard. The principle of cylinder locking mechanism is introduced, as well as the locking force calculation formulas.Meanwhile, the hydraulic force is reduced through optimizing the structural parameters of the locking finger.
