Electrical automation practical training platform

The utility model belongs to the technical field of electrical practical training tables, and particularly relates to an electrical automatic practical training table which comprises a workbench, fixing plates are fixedly connected to the left side and the right side of the bottom of an inner cavity of the workbench, and opposite sides of the two fixing plates are rotatably connected with positiveand negative threaded rods through bearings. By arranging the servo motor, the output end of the servo motor drives the main bevel gear to rotate, the main bevel gear drives the auxiliary bevel gearto rotate, the inner surface of the sleeve rotates left and right on the outer surface of the forward and reverse threaded rod in a threaded mode, and meanwhile the sleeve drives the driving plate tomove left and right, so that the driving plate drives the lengthening plate to move out of an inner cavity of the workbench; the practical training table has the advantages that the placement area ofthe table top can be increas
