The first bearing seat facilitates more accurate positioning of the drill bit of the drilling machine during drilling, and reduces swing deviation. The second bearing seat is moved and positioned to effectively reduce the hole spacing error and center error. Multiple drilling machines can drill multiple positions at one time, further improving drilling efficiency. The first drilling motor drives the first drilling shaft to rotate, so that the first drilling shaft and the drilling shaft sleeve cooperate to drive the drilling machine support rod to move forward and backward on multiple groups of drilling front and rear guide rods, further improving the mobile positioning accuracy. The second drilling motor drives the second drilling shaft to rotate, so that the second drilling shaft and the drilling shaft sleeve cooperate to drive the second bearing seat support rod to move forward and backward on multiple groups of drilling front and rear guide rods, further improving the mobile positioning accuracy.

[0023] In summary, the advantages of the present invention are to achieve automated drilling, save time and effort, and further improve drilling accuracy and drilling efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
