Aluminum welding end cover screw device

The utility model discloses an aluminum welding end cover screw device which comprises an outer machine shell, a connecting plate, a servo motor and a fixing box, the connecting plate is installed on the inner wall of the outer machine shell, a supporting rod is installed on the inner bottom wall of the outer machine shell, the fixing box is installed on the top of the supporting rod, a supporting table is installed on the top of the outer machine shell, and the servo motor is installed on the supporting table. And a servo motor is mounted at the top of the supporting table. By installing the brush plate, when an end cover screw is welded, generated waste residues can be scraped, waste impurities fall into the waste groove, cleaning and collecting of the waste impurities are completed, the servo motor rotates to drive the circular plate to rotate, the distance between a thin wire and the top of the rotating frame is reduced, the thin wire pulls the rotating frame, the top of the rotating frame moves downwards
