The invention belongs to the technical field of
machine tools, and provides a feeding and discharging device capable of being automatically operated on a numerically-controlled
machine tool. The device is provided with a door frame, the door frame is provided with a transverse module which perpendicularly moves on the door frame, a vertical module which moves left and right is arranged on the transverse module, the two sets of modules are formed in a crossing mode and driven by a
servo motor, a feeding
hand grasp device and a discharging
hand grasp device are arranged on the transverse module through a connecting
wrench, material grasping fingers are arranged on the feeding
hand grasp device and the discharging hand grasp device, the material grasping fingers are controlled through a grasp control component to clamp and loosen a workpiece, a door type internal-arranged mechanical arm is adopted, the
servo motor is adopted to drive a lead screw, a sliding table and the mechanical arm, automatic feeding and discharging of the workpiece can be achieved, two fingers are adopted by each hand grasp device for conducting parallel clamping, the fingers can be adjusted, clamping of workpieces of different specifications is achieved, the double grasps can work at the same time, and the production efficiency is improved by double.
