The utility model relates to the technical field of crane structure
machining, and discloses a door-shaped structure drilling
machine which comprises a drilling
machine body, a
rocker arm is arranged on the drilling
machine body, a sliding block is arranged on the
rocker arm, a drilling cutter set is arranged at the bottom of the sliding block, the drilling cutter set comprises a violent
drill, a
rocker arm locking rod is installed on the rocker arm, and the top end of the rocker arm locking rod is fixedly connected with the rocker arm. The rocker arm locking rod attracts a workpiece through the
magnet, and the rocker arm locking rod, the
magnet, the rocker arm and the drilling cutter set form a door-shaped structure. The drilling cutter group is connected with a cooling mechanism; the rocker arm locking rod and the
magnet are arranged and are convenient to disassemble, during drilling, the rocker arm is relatively fixed to a workpiece through the rocker arm locking rod and the magnet, the situation that the violent
drill, the rocker arm, the rocker arm locking rod and the drilling cutter set form a stable door-shaped structure due to vibration during drilling can be effectively prevented, and drilling stability and drilling precision are guaranteed.
