Novel aeration branch pipe drilling equipment and drilling method thereof

The invention discloses novel aeration branch pipe drilling equipment and a drilling method thereof, and belongs to the aeration pipe machining equipment technology field. By using the novel aerationbranch pipe drilling equipment and the drilling method thereof, supports and a rail arranged above the supports are included, a cross section of the rail is in a V shape, an aeration pipe is placed above the rail along a length direction, and a drilling machine is arranged above the aeration pipe. A plurality of limiting devices arranged on the supports on a left side and a right side of the railand a corresponding clamping position device are included. A positioning baffle plate is connected between the limiting devices and the corresponding clamping position device. A middle portion of a lower surface of the positioning baffle plate is in an arc shape and is matched with the aeration pipe. Therefore, when a previous clamping position device compresses the aeration pipe for punching, a latter clamping position de
