An automated tool includes a quick change spindle assembly (23). In another aspect of the present invention, the quick change spindle (45) includes an attachment assembly (49) for interchangeable fastener drivers (38). A further aspect of the present invention employs release member (75) to actuate a drive member (61) in the spindle assembly causing a retainer to uncouple a fastener driver with the spindle.

Die Erfindung betrifft einen Bithalter mit einem um eine Drehachse drehantreibbaren Antriebsschaft (1), mit einem eine Einstecköffnung (21) zum Einstecken eines Schraubendreherbits (33) aufweisenden Abtriebshülsenteil (20), mit einer Kupplungshülse (26), die den Antriebsschaft (1) zumindest teilweise umgibt und die in Richtung der Drehachse von einer Kupplungsstellung, in der eine der Kupplungshülse (26) zugeordnete Kupplungszone, bspw. eine Kupplungsanlagefläche (25') an einer Gegenkupplungszone, bspw. einer Kupplungsfläche (2') des Antriebsschaftes (1) anliegt, sodass eine Drehung des Antriebsschaftes (1) auf das Abtriebshülsenteil (20) übertragen wird, in eine Freilaufstellung verschieblich ist, in der die Kupplungszone und die Gegenkupplungszone jeweils in Freilaufabschnitten (3, 39) des Antriebsschaftes (1) bzw. Abtriebshülsenteiles (20) liegen, sodass eine Drehung des Antriebsschaftes (1) nicht auf das Abtriebshülsenteil (20) übertragen wird. Die Kupplungshülse (26) ist axial fest einer Betätigungshülse (10) zugeordnet ist, die an ihrem zur Einstecköffnung (21) weisenden Ende einen Anschlag ausbildet.
摘要:
The tool holder (2) according to the invention has a tubular main part (17), a locking element (6) which lies in a first channel (37) of the main part, and an actuating sleeve (7) which can be moved between a removal position and a locking position. The main part (17) has a depression (32) on the outside (22) and a second radial channel (37) which passes into the receiving area (19) starting from the depression (32). The actuating sleeve (7) has a radially pretensioned latching element which engages into the depression (32) in the removal position. An ejection element is guided in the second radial channel, said ejection element being pushed into a position which partly protrudes into the receiving area (19) when the latching element is in the removal position and is pushed out of the depression when the latching element is retracted from the receiving area (19).

An insert bit (10, 10a, 10b) includes a body (20, 20a, 20b) in a one piece structure extending longitudinally along a phantom axis (L), a first driving tip (23, 23a, 23b) manufactured from a first end of the body (20, 20a, 20b), a second driving tip (24, 24a, 24b) manufactured from a second end of the body (20, 20a, 20b), and a connecting structure (25, 25a, 25b) manufactured from the body (20, 20a, 20b) and extending between the first and second driving tips (23, 23a, 23b, 24, 24a, 24b) and having a hexagonal cross section in which two opposite peripheral edges space from one another with a distance defining a transverse width (WH) which is between 0.26-0.35 times of a longitudinal length of the insert bit (10, 10a, 10b) which defines a first length (L1).
摘要:
A wrench combining a sleeve comprises a wrench (1), a rotating sleeve (2), a locking strip (3), a hexagonal sleeve (4), and magnetic steel (5). The locking strip (3) is mounted at the bottom of the rotating sleeve (2). The hexagonal sleeve (4) is disposed in the rotating sleeve (2). The magnetic steel (5) sleeves one end of the hexagonal sleeve (4), so as to form a sleeve device. The wrench (1) penetrates through the sleeve device. The outline of the external circle of the locking strip (3) is of a gradually-opened surface structure, the rotating sleeve (2) matches the external circle contact surface structure of the locking strip (3) and the gradually-opened surface structure. The magnetic steel (5) absorbs a screw. When the sleeve device slides to a corresponding position on the wrench (1), the fixation or release of the sleeve device is controlled by means of the two gradually-opened surfaces, and therefore, functions of operating a screw or an inner angle screw are achieved, and the functionality of the wrench is effectively improved.
