Abstract
The utility model provides a numerical control dividing apparatus, which belongs to the technical field of machinery and solves the problems that current numerical control dividing apparatus is complex in structure, difficult to process and high in cost. The numerical control dividing apparatus comprises a base body, a main shaft, a dividing disc, a worm gear and a hourglass worm. The base body is provided with a servo motor and a worm shaft, the main shaft is supported rotatably on the base body and the hourglass worm is rotatably installed on the base body. The worm shaft penetrates through the hourglass worm and is coupled with an output shaft of the servo motor. The worm gear is installed on the main shaft and forms a transmission pair with the hourglass worm. The numerical control dividing apparatus provided by the utility model has the advantages of simple structure, high transmission precision and low cost.
