Abstract

The lever clamping fixture has pistons (18,20) connected to a piston rod (6) and is operated by compressed air. The piston rod is connected with a joint lever (8) by a joint (9), on which a clamping arm (19) is mounted. The former piston is loaded in a cylinder space (4a) with compressed air during the return stroke of the piston rod.

Description

Der zum Patent angemeldete Druckluft betätigte Hebelspanner hat bei seiner schmalen Baubreite von nur 60 mm einen Doppelkolben von 40 + 50 mm Durchmesser. Durch diesen Doppelkolben wird bei einem Luftdruck von 5 bar ein Drehmoment von 250 Nm erreicht.Of the Patent-pending compressed air actuated lever clamps included its narrow width of only 60 mm a double piston of 40 + 50 mm diameter. Through this double piston is at an air pressure of 5 bar achieved a torque of 250 Nm.

Arbeitsweise:Operation:

Durch den Eintritt der Druckluft durch die Bohrung 1 und der Rückluftdrossel 2 in den Zylinderraum 4 durch die Druckluft gegen den Kolben 18 und gleichzeitig durch die Bohrung 5 der Kolbenstange 6 in den Zylinderraum 7 gegen den Kolben 20, wodurch die Kolbenstange 6 mit dem Gelenkhebel 8 an dem sich der Hebel 9 mit dem Spannarm 19 befindet gegen den Anschlag 13 fährt, womit die Wiederholgenauigkeit des Spannhebel 19 garantiert wird. An dem Hebel 9 befindet sich die Kurve 10 welche die Steuerstange 11 betätigt und über den Positionsgeber 17 die Spannposition des Spannhebels 19 berührungslos anzeigt, und über den Stufenlos verstellbaren Positionsgeber 12 durch den Anschlagpuffer 3 Festgelegten Öffnungswinkel des Spannarmes 19 anzeigt. Für den Rücklauf des Spannarmes 19 tritt die Druckluft durch die Bohrung 15 der Rückluftdrossel 14 in den Zylinderraum 4a ein und schiebt den Kolben 18 mit der Kolbenstange 6 gegen den Anschlagpuffer 3 in die Ausgangsstellung zurück Beim Ausfall von Druckluft in der Spannposition des Spannhebels 19 kann der Spannhebel 19 aus der Haltekraft-Stellung durch betätigen des Handauslösers 22 mit dem Anschlag 13 gelöst werden und von Hand in die Ausgangsstellung zurück gestellt werden.By the entry of compressed air through the hole 1 and the return air throttle 2 in the cylinder room 4 by the compressed air against the piston 18 and at the same time through the hole 5 the piston rod 6 in the cylinder room 7 against the piston 20 , causing the piston rod 6 with the toggle lever 8th where the lever is 9 with the clamping arm 19 is against the stop 13 moves, bringing the repeatability of the clamping lever 19 is guaranteed. At the lever 9 is the curve 10 which the control rod 11 actuated and via the position transmitter 17 the clamping position of the clamping lever 19 contactless, and via the infinitely variable position sensor 12 through the stop buffer 3 Fixed opening angle of the clamping arm 19 displays. For the return of the clamping arm 19 the compressed air passes through the hole 15 the return air throttle 14 in the cylinder room 4a and pushes the piston 18 with the piston rod 6 against the stop buffer 3 back to the starting position If compressed air fails in the clamping position of the clamping lever 19 can the cocking lever 19 from the holding force position by pressing the manual release 22 with the stop 13 be solved and returned to the original position by hand.
