The valve stem processed in this way falls and is discharged through the guide plate 10. The drilling machine 12 moves up while the rotating drum 81 rotates clockwise. After the valve stem is unloaded, the rotating drum 81 rotates counterclockwise to reset so that the placement groove is located at the upper right again, and the loading, drilling and unloading operations are performed reciprocatingly, thereby achieving the purpose of facilitating automatic loading and unloading, and solving the problem that the valve stem needs to be clamped and positioned one by one during the drilling process. The loading and unloading process increases the labor of the operators, and intermittent automatic loading and unloading cannot be performed, and the drilling operation cannot be performed continuously, which reduces the drilling efficiency.
