The invention discloses an automobile brake pad production dedusting-type drilling device which comprises a bottom plate and a lifting plate. Two side plates are symmetrically and fixedly mounted on left and right sides of the bottom plate, a top plate is fixedly mounted at the tops of the side plates, a first screw is rotatably mounted on the lower side of each side plate, left and right sides ofthe lifting plate are in threaded connection with the two first screws respectively, a plurality of placement grooves are uniformly formed in the lifting plate, and a dedusting device is fixedly mounted on the bottom plate. A drill bit is driven to move up and down through cooperation of second screws and sliding rods for the convenience of drilling brake pads, the lifting plate is driven to moveup and down by utilizing cooperation between the first screws and the lifting plate for the convenience of being adapted to the brake pads different in thickness; the dedusting device is arranged toabsorb dust and chippings generated during drilling, so that environment of a drilling workshop is avoided being polluted.
