The invention discloses a hole drilling device used for furniture plate machining. A supporting base is included, and a device framework is arranged on the upper portion of the supporting base, and isinternally provided with a square frame; the square frame and the device framework are fixedly connected; pressing devices are arranged on the upper portions of the two sides of the square frame, andare distributed in an axial symmetry manner; an upper hole drilling machine is arranged between the pressing devices, and a lower hole drilling machine is arranged on the lower portion of the squareframe; and the upper hole drilling machine and the lower hole drilling machine are distributed in parallel. Due to the fact that the upper portion of the square frame is provided with the upper hole drilling machine and the lower hole drilling machine is arranged on the lower portion of the square frame, the upper hole drilling machine and the lower hole drilling machine can be used for performinghole drilling on the two side faces of a plate at the same time, the operation convenience and fastness are improved, and the work efficiency of hole drilling is improved.
