Claims (9)
- - mehreren Verbindungsstangen (21), die symmetrisch parallel zueinander an den Ecken einer Vorderplatte (22) und einer Rückplatte (23) angebracht sind, und mit einer beweglichen Platte (24), die auf den Verbindungsstangen läuft und zwi schen der Vorder- und der Rückplatte positioniert ist;
- - einem an der Rückplatte angebrachten Servomotor (25), der Kraft zum Betreiben der Klemmeinheit liefert;
- - einem Riemen-Zahnrad-Mechanismus (26), der dem Servomotor zugeordnet ist, um die von diesem erzeugte Drehmomentkraft und Drehzahl zu übertragen;
- - einem Kugelumlaufspindel-Übertragungsmechanismus mit einer Kugelumlaufspindel (270) und einer mit dem Riemen-Zahnrad- Mechanismus verbundenen Führungsvorrichtung (271) zum Umset zen der vom letzteren übertragenen Drehmomentkraft in eine axiale Schubkraft, wobei die Führungsvorrichtung mit einem Gewindeloch versehen ist, in dem die Kugelumlaufspindel lau fen kann; und
- - einem Umschalt-Verbindungsmechanismus (28) zum Verbinden der Rückplatte und der beweglichen Platte und zum Aufnehmen der axialen Schubkraft vom Kugelumlaufspindel-Übertragungs mechanismus, um die bewegliche Platte so anzutreiben, dass sie sich entlang den Verbindungsstangen bewegt.
- - A plurality of connecting rods ( 21 ) which are mounted symmetrically parallel to one another at the corners of a front plate ( 22 ) and a rear plate ( 23 ), and with a movable plate ( 24 ) which runs on the connecting rods and between the front and the Back plate is positioned;
- - A servo motor ( 25 ) attached to the rear plate, which provides power for operating the clamping unit;
- - a belt gear mechanism ( 26 ) associated with the servo motor to transmit the torque force and speed generated thereby;
- - A ball screw transmission mechanism with a ball screw ( 270 ) and a guide device ( 271 ) connected to the belt-gear mechanism for converting the torque force transmitted from the latter into an axial thrust force, the guide device being provided with a threaded hole in which the Ball screw can run; and
- - A switching link mechanism ( 28 ) for connecting the back plate and the movable plate and receiving the axial thrust from the ball screw transmission mechanism to drive the movable plate so that it moves along the connecting rods.
