Novel extra-high-voltage steel plate high-precision drilling equipment

The utility model discloses novel extra-high voltage steel plate high-precision drilling equipment. The drilling machine structurally comprises a rack, a Z-axis moving device, an X-axis moving device,a Y-axis moving device and a drill bit assembly. According to the utility model, the L-shaped support plate is arranged on the driving device of the drill bit assembly; an infrared emitter is mountedat the bottom of the support plate; the infrared emitter and the drill bit are in the same vertical state; when a steel plate is drilled; controlling the infrared emitter to emit infrared light; themethod comprises the following steps: aligning a required drilling position with infrared light; fast alignment, the top end of the support plate is connected with a Y-axis moving device through two connecting rods; when the drill bit assembly moves downwards, the supporting plate is rotated through cooperation between the two connecting rods, the supporting plate is made to rotate forwards, the situation that drilling of t
