DEVICE FOR SETTING A CONNECTING ELEMENT

The invention relates to a device (10) for setting a connecting element (100, 300) with a top-side drive structure (22, 44), comprising a feed device (12) for applying an axial force, a rotary spindle (14, 40. 68,82, 140) and a drive bit (20, 42, 60, 70, 80, 142, 242) connected to same, which has drive structures (22, 44) arranged circumferentially and at the end in a setting direction (S) in order to interlockingly cause the connecting element (100, 300) to rotate, wherein the drive bit (20, 42, 60, 70, 80, 142, 242) has an axial through-opening, and the device also comprises a suction unit (18) with which air can be suctioned out at the end side of the drive bit (20, 42, 60, 70, 80, 142, 242), characterised in that an insert element (24, 50, 72, 150) is provided having a suction surface (26, 54) on the end side, which circumferentially borders a suction cross-section (30), wherein the insert element (24, 50, 72, 150) is designed in such a way that the suction surface (26, 54) can move relative to the drive bit (20, 42, 60, 20 70, 80, 142, 242) in the axial direction, and a negative pressure can be transmitted from the side of the insert element (24, 50, 72, 150) facing away in the setting direction (S) to the suction surface (26, 54) of the insert element (24, 50, 72, 150), wherein, before the suctioning of a connecting element (100, 300), the suction surface (26, 54) adopts a first end position which is spaced apart from the end-side edge region of the through-opening in the setting direction (S), and adopts a second position, shifted opposite the setting direction (S), during the setting process. La invención se refiere a un dispositivo (10) para fijar un elemento de conexión (100, 300) con una estructura de accionamiento del lado superior (22, 44), que comprende un dispositivo de alimentación (12) para aplicar una fuerza axial, un husillo giratorio (14, 40. 68,82, 140) y una broca de accionamiento (20, 42, 60, 70, 80, 142, 242) conectada al mismo, que tiene estructuras de accionamiento (22, 44) dispuestos circunferencialmente y al final en una dirección de ajuste (S) para hacer que el elemento de conexión (100, 300) gire entrelazado, en el que la broca de accionamiento (20, 42, 60, 70, 80, 142, 242) tiene una abertura axial, y el dispositivo también comprende una unidad de succión (18) con la que se puede aspirar aire en el lado final de la broca de accionamiento (20, 42, 60, 70, 80, 142, 242), caracterizado porque un elemento de inserción (24, 50, 72
