The invention discloses an intelligent core drilling machine. The intelligent core drilling machine comprises a mechanical arm, a control system for controlling the mechanical arm to work, a core drilling tool head for core drilling, a vibrating and compacting tool head for compacting and a filling head for weighing a material filling a hole. The mechanical arm is driven by a servo motor installed on the mechanical arm, and the work end of the mechanical arm is detachably connected with all the tool heads and all the tool heads are driven by a power device. The control system is used for controlling operation of the servo motor on the mechanical arm through data connection; a ten-axis sensor is arranged on each tool head and used for measuring torque exerted on the work part of the tool head, and the ten-axis sensors return collected data to the control system, which is used for controlling the servo motor on the mechanical arm to operate; a satellite positioning module for positioning is arranged on the control system. The full process of core sample drilling and hole repairing is automatic, accurate and efficient.
