The invention discloses a deep hole drilling device which comprises a main rack and a main guide rail laid on the main rack. The main guide rail is sequentially provided with a drilling device, a driven clamp device and a driving clamp device. The driven clamp device comprises a driven installation machine base and driven hollow shafts arranged on the driven installation machine base, and driven clamping blocks are arranged at the outer end of the driven hollow shafts. The driving clamp device comprises a driving installation frame, an installation plate arranged on one side of the driving installation frame and multiple sets of gear motors fixed to the installation plate through installation supports. The output ends of the gear motors are connected with corresponding telescopic combination shafts through synchronous transmission mechanisms, a hydraulic cylinder device used for driving the combination shafts to move back and forth is arranged on the outer portion of the telescopic combination shafts, and driving clamping blocks are arranged at the output ends of the telescopic combination shafts. The deep hole drilling device can clamp workpieces to enable the workpieces to rotate, and geometric errors caused by immobilization of the workpieces can be eliminated while drilling is conducted.
