This invention relates to the field of clamping mechanism technology, specifically an automatic clamping mechanism for drilling large filter plates. It includes a base, a transverse limiting reference, a lower pressure head, and a longitudinal moving base with transverse moving bases symmetrically arranged on the left and right sides. The transverse moving base is equipped with a longitudinal limiting reference, an automatic drilling mechanism, a side-push assembly, and a self-locking stabilizing assembly. In this invention, after the transverse moving base moves to the longitudinal coordinate position of the hole to be drilled along with the longitudinal moving base, the longitudinal limiting reference on the transverse moving base limits and clamps the workpiece. Simultaneously, the automatic drilling mechanism, using the transverse limiting reference as the installation reference and moving synchronously with the transverse moving base, automatically completes the calibration of the transverse coordinate of the corresponding hole to be processed. During the above process, the side-push assembly automatically applies a forward thrust as the transverse moving base moves, ensuring that the workpiece remains tightly against the transverse limiting reference, thus enhancing the accuracy of the transverse limiting reference. The longitudinal limiting reference moves with the transverse moving base, preventing the hole to be drilled from being obstructed during clamping.
