The installation frame 508 is connected with the drill bit 509 by bolts. When one of the drill bits 509 is located directly below the installation disk 506, the axis of the drill bit 509 coincides with the axis of the output shaft of the first motor 505. One of the rotating shafts of the installation disk 506 is fixedly connected with the output shaft of the second motor 507. The second motor 507 is fixedly installed on the vertical plate 504. A card slot 510 is provided on one side of the installation frame 508. A fixing frame 511 is fixedly installed on the vertical plate 504. A horizontal cylinder 512 is fixedly installed at the bottom end of the fixing frame 511. A clamping rod 513 is movably installed inside the horizontal cylinder 512. One end of the clamping rod 513 is clamped into the fixing frame 511 located at the installation plate 506. Inside the card slot 510 on the installation frame 508 directly below the mounting plate 506, a spring 514 is fixedly installed on the end of the card rod 513 away from the installation frame 508, and one end of the spring 514 is fixedly connected to the inner wall of the end of the transverse tube 512 away from the installation frame 508.

[0028] Since a plurality of drill bits 509 are installed at equal angles on the outer side of the mounting plate 506, when the diameter of the hole to be punched in the metal casting needs to be changed, the second motor 507 is turned on to rotate the output shaft of the second motor 507, driving the drill bit 509 of the corresponding diameter on the mounting plate 506 to be adjusted to the position below the mounting plate 506, and then the second cylinder 502 is turned on to move the hanger 501 downward, and at the same time the first motor 505 is turned on to rotate the mounting plate 506, and the axis of the drill bit 509 located in the positive direction of the mounting plate 506 coincides with the axis of the output shaft of the first motor 505, thereby driving the drill bit 509 to rotate to punch the metal casting;

[0029] When drilling, the electromagnet 516 is energized to generate a repulsive force on the magnetic block 515, pushing the clamping rod 513 to move outward, so that the end of the clamping rod 513 is inserted into the clamping groove 510 on the mounting frame 508 directly below the mounting plate 506, thereby improving the fixing effect of the mounting plate 506. At the same time, under the repulsive force of the electromagnet 516, the clamping rod 513 presses and fixes the drill bit 509 in the drilling state, thereby improving the drilling stability and reducing the vibration of the drill bit 509 when drilling.
