The invention discloses a revolving door stand column threaded hole drilling device provided with a limiting structure. The revolving door stand column threaded hole drilling device comprises a lowerframe, an upper frame and a supporting support connecting the upper frame and the lower frame and a movable drill bit device. The upper frame comprises two parallel supporting beams arranged at intervals, and the two supporting beams are connected through a plurality of connection beams which are arranged at intervals. When the drilling device is used, a to-be-machined revolving door stand columnis fixed to the upper frame in the arrangement direction of a screw rod, the movable drill bit device moves through driving of a driving motor, meanwhile, drilling is conducted on the revolving door stand column, the efficiency is high, and the machining quality is good. In addition, in the using process, the limiting device is arranged on the upper frame, the revolving door stand column is limited through a limiting air cylinder and a side fixing block, so that the revolving door stand column is prevented from moving in the machining process, using is convenient and rapid, and the machining quality is ensured.
