The utility model relates to a braking mechanism for a rotating table, which is hydraulically driven and comprises braking components uniformly distributed along the periphery of a rotating disc shaft of the rotating table, and the braking components are mounted at the bottom of a table top of the rotating table and comprise pistons and sealing covers for sealing the pistons and hydraulic oil cylinders. A disc brake pad is installed at the bottom of the piston and used for tightly braking the table top and the base of the rotary table in a friction braking mode. According to the utility model, the design of annular arrangement along the outer side of the table-board disc shaft is adopted, and the hydraulically-driven disc brake is adopted, so that the braking torque can be effectively improved, the sensitivity is extremely high, the braking distance is extremely short, and the precision is extremely high. 本实用新型涉及一种回转工作台刹紧机构，所述刹紧机构采用液压驱动，所述刹紧机构包括沿回转工作台旋转盘轴周沿均匀布设的刹紧组件，所述刹紧组件安装在回转工作台的台面底部，包括活塞和将活塞与液压油缸封装的封盖，所述活塞
