Abstract

The invention relates to a numerical control side tool carrier structure of a vertical lathe. A servo motor is connected with a speed reducer. The output shaft of the speed reducer is connected with a ball screw through a coupling. The speed reducer is fixedly arranged on a too carrier box body. The ball screw is screwed into a cornering nut. The cornering nut is fixedly arranged on a ram by adjusting a second adjusting washer. A deep groove ball bearing is installed in the tool carrier box body. The shaft end of the ball screw penetrates through the inner hole of the deep groove ball bearing. An iron wedge is installed on the tool carrier box body. A pressing plate is fixedly arranged on the tool carrier box body. A tool chuck is installed on the ram. The numerical control side tool carrier structure of the vertical lathe has the advantages that the structure compact and reasonable; since the servo motor is used to drive the ball screw to rotate to realize feeding and the side tool carrier is controlled by using a numerical control device, the feeding amount is easy to control, the feeding is accurate and the machining accuracy is greatly improved.
