At the same time, the L-shaped telescopic rod 507 and the connecting rod 506 are also driven to be adjusted under the elastic action of the spring 508. After adjusting to a suitable size for the inner diameter of the flange, place the flange of the drilling to be processed between the fixed block 505 and the movable clamp block 503 for clamping and fixing. Under the clamping of the upper, middle and lower parts of the stabilizing assembly 5, the stability of the flange being clamped is ensured, and the accuracy during flange drilling is improved. Finally, connect an external blower to the chip removal assembly 6. Since the movable clamp block 503, the connecting rod 506 and the L-shaped telescopic rod 507 are all hollow and connected in communication, under the increased blowing action of the blower, the gas is blown out after being pressurized from the through hole 601 and the round hole 602. And the through hole 601 is in an inclined opening shape, and the round hole 602 is in a straight opening shape, so that the pressurized gas can be blown to the entire surface of the flange, realizing the function of quickly removing waste chips.
