Abstract

The utility model relates to a worm wheel drive graduation workbench, comprising a slider seat, a piston, a piston connector, a rotary table, a workbench, a motor, a worm wheel and a worm. The piston is connected to the center of the slider seat. The inner wall of the piston is matched with an outer ring of the piston connector. The top of the piston connector is connected with the rotary table the upper part of which is connected with the workbench. The bottom of the rotary table is provided with two key slots which are matched with corresponding key blocks on a steel underlay. The steel underlay is fixed on the worm at the central part of a round table of the slider seat. The worm wheel is joggled with the worm. The worm is connected with a motor through a synchronous belt drive pair. The worm wheel cannot axially move, thereby reducing the abrasion between the worm wheel and the worm, enabling the transmission to be stable and generating little vibration and low noise. The bearing capability of the worm wheel drive graduation workbench is strong; the influence of a processed work piece to the workbench is reduced; and the graduation accuracy is ensured.
