While the device of the present invention is used, the clamping jaw assembly clamps the workpiece and moves between the chamfering piece and the mounting plate, and then the support piece rises under the action of the fourth drive mechanism, and then clamping jaws of the clamping jaw assembly are released, so that the workpiece falls on an upper end of the support piece, and then the support piece is reset under the action of the fourth drive mechanism, and then the fifth drive mechanism drives the positioning piece to move, the positioning piece is pressed against the workpiece, so that the auto-rotation of the workpiece is limited. Finally, the chamfering piece is downwards moved under the action of the third drive mechanism, and the chamfering piece is auto-rotated under the action of the fourth drive mechanism to perform a chamfering operation; the first drive mechanism drives the clamping jaw assembly to be moved leftwards and rightwards, as to achieve the movement of the workpiece in a feeding area, a processing area and an unloading area, so the production efficiency is improved. The present invention is capable of, through the third drive mechanism, guaranteeing that the chamfering piece may not be inclined or moved leftwards and rightwards, and through the fifth drive mechanism, achieving positioning of the workpiece, as to guarantee the angle of the inner hole chamfering and the chamfering uniformity. Herein, through the third drive mechanism, the chamfering piece may be downwards moved while it is in contact with the workpiece, as to guarantee the chamfering depth of the inner hole; and the third drive mechanism may be an air cylinder or an electric push rod.
