Full-automatic numerical control drilling machine for any pitching angle

The invention provides a full-automatic numerical control drilling machine with any pitching angle. The full-automatic numerical control drilling machine comprises a water drill, a variable-angle feeding mechanism, a middle rack, a lower rack, a leveling device and a lifting device. The variable-angle feeding mechanism is provided with an air cylinder, a sliding guide rail and a hinged shaft, the air cylinder stretches to enable a pulley block and a steel wire rope to provide constant thrust for cutting of the water drill, the air cylinder retreats to enable the pulley block and the steel wire rope to pull the water drill out of the cutting position, the sliding guide rail provides guidance for cutting of the water drill, and the hinged shaft is arranged in the middle rack in a sleeved mode. And the variable-angle feeding mechanism rotates around the hinged shaft. The middle rack is provided with a stand column capable of sliding up and down along the lower rack, one end of the electric angle adjusting mechan
