Automatic feeding manipulator of punching machine

The invention discloses an automatic feeding manipulator of a punching machine. Through the automatic feeding manipulator, the machining efficiency of the punching machine can be greatly improved; thefeeding and discharging efficiency is improved through an indexing rotating method; during machining, workpieces cannot get away from the manipulator, the machining precision and the machining efficiency are improved. During machining and feeding, when the punching machine conducts feeding and punching, mechanical gripper grabbing assemblies grabs the workpieces, and the lower ends of the workpieces are located in workpiece passing holes of an indexing rotary disk. The indexing rotary disk rotates, the workpieces are moved to the locations under punch pins, feed cylinders descend to conduct feeding to make the lower end of a punching and clamping assembly be located to a punching bottom die, and then the corresponding mechanical gripper grabbing assembly loosens the corresponding workpiece, the workpiece falls into the corresponding stamping and clamping assembly and clamped by the stamping and clamping assembly, and then the workpiece is subjected to stamping or punching through thecorresponding punch pin. After completion of machining, the indexing rotary disk rotates to drive the punching and clamping assemblies to rotate to the discharging position, and the punching and clamping assemblies loosen the workpieces to complete discharging.
