Pressure device for a clamping system
The present invention relates to a pressing device for a clamping system. The pressing device is coupled to a clamping element of the clamping system. For this purpose, the pressing device has a pressing arm, which is operationally linked at one end to a clamping element of the clamping system and has an oblong hole on the diametrically opposite free end, in which a fastening rod for a clamping head is situated so it is longitudinally displaceable and rotatable. The pressing device additionally has a twist lock, which secures the angle between clamping head and pressing arm, having a twist lock plate and a lock pin.
1. A pressing device comprising a pressing arm and clamping head, the pressing arm having an oblong hole in which a fastening rod for the clamping head is situated such that the fastening rod is longitudinally displaceable and rotatable, the fastening rod fixing the clamping head to the pressing arm so that the clamping head is also longitudinally displaceable and rotatable, wherein the clamping head has a twist lock which secures a variable horizontal angle between clamping head and pressing arm, the twist lock comprising a twist lock plate oriented perpendicular to a lock pin that is oriented parallel to the fastening rod.
2. The pressing device according to claim 1 , wherein the twist lock plate) is situated orthogonally to the oblong hole of the pressing device and carries the fastening rod, and the lock pin projects into the oblong hole at a distance from the fastening rod, the twist lock plate having the clamping head and defining the horizontal angle between clamping head and pressing arm and securing this defined angle through the lock pin.
3. The pressing device according to claim 1 , wherein the twist lock plate and the clamping head are in one piece.
4. The pressing device according to claim 2 , characterized in that the lock pin ( 17 ) and the clamping head ( 10 ) are situated diametrically opposite one another in relation to the fastening rod ( 15 ) on the twist lock plate ( 16 ).
5. The pressing device according to claim 1 , wherein the twist lock plate has a curved hole pattern track diametrically opposite to the clamping head in relation to the fastening rod for defining and securing the angle between clamping head and pressing arm, the lock pin being fixable in the hole pattern track.
6. The pressing device according to claim 1 , wherein the twist lock plate has a curved oblong hole slot diametrically opposite to the clamping head in relation to the fastening rod for defining and securing the horizontal angle between clamping head and pressing arm, the lock pin being fixable in the oblong hole slot.
7. The pressing device according to claim 1 , wherein the pressing device has an adapter plate for enlarging the horizontal angle between clamping head and pressing arm, the adapter plate being situated orthogonally to the oblong hole and between the pressing arm and the twist lock plate having clamping head.
8. The pressing device according to claim 7 , wherein the adapter plate has a through hole for the fastening rod and, at a distance thereto, a hole for the lock pin.
9. The pressing device according to claim 8 , wherein the adapter plate has at least one further through hole, which is situated on a circular line around the through hole for the fastening rod, the circular line having a radius, which corresponds to a distance between fastening rod and lock pin.
10. The pressing device according to claim 9 , wherein the further through hole of the adapter plate has a removable connection element for defining and securing the horizontal angle between pressing arm and clamping head and for mechanically connecting twist lock plate and adapter plate.
11. The pressing device according to claim 1 , wherein the clamping head is forked.
12. The pressing device according to claim 1 further comprising a cantilever, which lengthens the pressing arm, and which has a fastening rod and a lock pin on a chucked end, which are situated in the oblong hole of the pressing arm, and has threaded holes on a diametrically opposite free end for a second fastening rod and a second lock pin.
13. The pressing device according to claim 1 further comprising a clamping element, which may be actuated and exerts a clamping force on the clamping head.
14. The pressing device according to claim 13 , wherein the clamping element has a clamping lever for applying a clamping force.
15. The pressing device according to claim 13 , wherein the pressing arm of the pressing device is operationally linked at one end to the clamping element and has the oblong hole on the diametrically opposite free end.
