When the surface of the workpiece is regular and flat, the workpiece is placed on the surface of the placement block 64, and the bottom of the workpiece is suction-fixed by the four magnets 65. At the same time, the four clamping mechanisms 63 are adjusted to clamp and fix the periphery of the workpiece. The clamping is firm and reliable, preventing shaking. The motor 5 is started to drive the lead screw 3 to rotate, and the placement mechanism 6 slides along the first chute 101 as the lead screw 3 rotates. When the placement mechanism 6 slides to directly below the punching mechanism 2, the motor 5 is turned off, and the telescopic rod 23 is started to push the slide plate 25 and the drill bit 28 to move downward. At the same time, the servo motor is started to drive the drill bit 28 to rotate, and the drill bit 28 punches a specified position of the workpiece. After the punching is completed, the telescopic rod 23 resets to drive the drill bit 28 to reset, preparing for the next punching.
