The utility model provides a universal clamping device for drilling hinges on double-eared bearings, which comprises a base, a screw base, a screw, a drilling template and a guiding clamping block; a base comprises a side and a bottom; a swallow-tail groove is arranged on the side of the base from top to bottom; a screw base is fixed on the upper side of the base; a threaded through-hole is arranged in the center of the screw base; and a screw and a screw base are arranged in the screw base. When the screw rotates itself, the screw can move along the axial direction of the screw base; the back end of the drilling template and the guide clamping block has a dovetail block and is in the dovetail channel on the side of the base; the dovetail block of the drilling template and the guide clamping block has a through hole, and the screw passes through the through hole on the dovetail block of the drilling template and the guide clamping block, and then the guide clamping block. The through hole on the dovetail block of the tight block is connected with the guide clamping block. When the screw rotates, the guide clamping block can move with the screw synchronously along the axial direction; the front part of the drilling template and the guide clamping block is provided with a coaxial through hole, and a quick release drill sleeve is arranged in the coaxial through hole. The utility model guarantees the coaxiality and cylindricity of the two holes on both ears, and improves the quality of the two holes on the drilling and reaming ears.
