Referring to fig. 3 to 4, the present invention provides an automatic positioning table for cutting a toothed plate, comprising: the cutting device comprises a cutting working platform 1 and a positioning structure arranged on the cutting working platform 1; the positioning structure comprises a positioning column 2, a central positioning gas claw 5 and a sliding assembly; the central positioning gas claw 5 and the positioning column 2 are arranged at the front end of the cutting working platform 1; the central positioning gas claw 5 comprises a cylinder I7, a first claw 6 and a second claw 8, the cylinder I7 is fixed on the cutting working platform 1, the first claw 6 and the second claw 8 are arranged at the top of the cylinder I7, and are driven by the cylinder I7 to move transversely and relatively along the cutting working platform 1; the sliding assembly is installed at the rear end of the cutting working platform 1 and slides longitudinally along the cutting working platform 1. During actual use, a workpiece 19 to be cut is hoisted to the cutting working platform 1, the central tooth of the workpiece 19 to be cut is pushed to the position near the central positioning gas claw 5, the sliding assembly is started, the workpiece 19 to be cut is tightly propped against the positioning column 2, and at the moment, the positioning column 2 and the sliding assembly cooperate to complete the longitudinal positioning of the workpiece 19 to be cut. The central positioning gas claw 5 is started to perform transverse positioning, and due to the fact that the gas claw has synchronism of two sides, the cylinder I7 drives the first clamping claw 6 and the second clamping claw 8 to expand in the central tooth of the workpiece to be cut 19, the workpiece to be cut 19 is transversely pushed to move until the first clamping claw 6 and the second clamping claw 8 are simultaneously in contact with the inner side of the central tooth, the workpiece to be cut 19 stops moving, and at the moment, the workpiece to be cut 19 is symmetrically distributed along two sides of the central positioning gas claw 5.
