Steel formwork machining device

The invention relates to the technical field of steel formwork machining, and discloses a steel formwork machining device which comprises a centrifugal compression structure, a medium flowing structure and a medium driven telescopic structure, and the medium driven telescopic structure generates a downward moving trend after bearing medium pressure generated by centrifugal force and can generate a rotating state; a drill bit is fixedly mounted at the bottom rotating end of the medium driven telescopic structure. According to the steel formwork machining device, the driving motor is adopted, rotating kinetic energy needed by drilling of the drill bit can be generated, the rotating speed can serve as a power source to generate additional centrifugal force, the centrifugal force is used for controlling the downward pressing force of the drill bit, the effective utilization rate of the kinetic energy is effectively increased, and in addition, the service life of the drill bit is prolonged.
