Lifting device of numerically controlled lathe

The utility model provides a lifting device of a numerically controlled lathe. The back face of the lifting assembly is fixedly connected to the front face of the machine body, the lifting assembly comprises a U-shaped frame, the back face of the U-shaped frame is fixedly connected to the front face of the machine body, the bottom of the inner side of the U-shaped frame is rotationally connected with two threaded rods, and the circumferential side faces of the two threaded rods are in threaded connection with a moving plate; the two sides of the movable plate are slidably connected with the inner side of the U-shaped frame. According to the lifting device of the numerical control lathe, the two threaded rods rotate to drive the moving plate to move upwards, the moving plate moves to drive the sliding plate to move upwards, the sliding plate is pushed backwards after moving to a proper position, then the sliding plate drives a workpiece to move into the machine body, the structure is simple and practical, and
