Definitions
- the invention relates to a clamping device according to the preamble of patent claim 1.
- a tensioning device of the type mentioned is according to the DE 196 45 778 A1 known.
- This consists of a rotatably mounted in a housing hollow shaft (Spannarmwelle) to which a clamping element (clamp arm) attachable and which is provided to form a toggle mechanism with a lever arm (positioning extension), wherein an intermediate member on the one hand articulated to the lever arm and on the other hand articulated with a axially movable actuator (actuating rod) of a drive element is connected, wherein in the hollow shaft connected to a hand lever inner shaft is arranged, which has a pin element (setting pin), which passes through a slotted guide (link slot) on the hollow shaft and can be brought into operative connection with the toggle mechanism, wherein a the inner shaft against the hollow shaft in Hauptaxialraum spanning spring element is provided.
- the toggle mechanism with the help of the hand lever either to solve or bring in the so-called fürtot Vietnameseposition, especially if the actuator of the drive element (pneumatic cylinder, hydraulic cylinder, electric drive or the like) is freely movable ,
- the aspect is taken into account that with a non-hollow clamping arm shaft torque insertion is in this unfit to take influence on the toggle mechanism.
- the invention has for its object to improve a clamping device of the type mentioned. In particular, a more compact design should be created.
- the spring element is arranged in the interior of the hollow shaft.
- the solution according to the invention is distinguished by the fact that the spring element originally arranged on the outside of the hollow shaft (see in particular FIG. 5) DE 196 45 778 A1 ) is now placed inside the hollow shaft, and particularly preferably in such a way that the spring element is designed as arranged in an annular gap between the inner and the hollow shaft helical compression spring.
- the in the FIGS. 1 to 4 illustrated clamping device consists in a known manner from a rotatably mounted in a housing hollow shaft 1, on which a clamping element (in particular clamping arm 17) rotationally fixed and which is provided to form a toggle mechanism with a lever arm 2.
- a clamping element in particular clamping arm 17
- the lever arm 2 is rotationally connected to the span side in cross-section polygonal, preferably square-shaped hollow shaft 1 connected.
- an intermediate member 3 is on the one hand articulated to the lever arm 2 and on the other hand hingedly connected to an axially movable actuator 4 of a drive element.
- the actuator 4 is formed fork-shaped member-side, wherein between two fork parts, an abutment 16 is arranged for the pin member 7 (see FIG. 1 ).
- the lever arm 2 is on the fork side fork-shaped (or two tabs) formed, wherein between two fork parts or tabs the intermediate member 3 articulated is.
- a cylindrical through hole 13 is provided on the hollow shaft 1 for forming the hollow shaft 1, wherein the inner shaft 6 is formed on both sides of the hollow shaft 1 protruding.
- the spring element 9 which is preferably designed as the helical compression spring surrounding the inner shaft 6, is arranged in the interior of the hollow shaft 1.
- this proviso has the advantage that the clamping device can be made more compact overall.
- a spring element 9 receiving annular gap space 10 is provided between the hollow shaft 1 and the inner shaft 6, wherein one of the two bushes 11 is formed as an abutment for the spring element 9. More specifically, while the inner diameter of the bushing 11 corresponds to the outer diameter of the inner shaft 6, so that the latter can be easily rotated (with respect to the hollow shaft 1), wherein at the same time formed each bushing 11 frictionally (for example by pressing) with the hollow shaft 1 is.
- the inner shaft 6 has a shaft shoulder 12 as an abutment for the spring element 9.
- This shaft shoulder 12 is formed as a cylindrical contact surface to the inner wall of the hollow shaft 1, wherein the shaft shoulder 12 has a matching the inner diameter of the hollow shaft 1 outer diameter.
- the outer diameter of the bushing 11 corresponds to the outer diameter of the shaft shoulder 12.
- the journal element 7 is arranged in the region of the shaft shoulder 12 on the inner shaft 6.
- the tensioning device according to the invention works as follows:
- the hand lever 5 is again operated, this time of course in the other direction.
- the pin member 7 is fixed due to the force of the spring element 9 in parallel to the main axis of the hollow shaft 1 oriented guide portion 14. Only at the moment when a further rotational movement of the hand lever 5 (due to the toggle mechanism) is no longer sufficient to move the actuator 4 further up, the force of the spring element 9 are overcome, so that the pin member 9 can get into the transverse to the main axis of the hollow shaft 1 oriented guide portion 15. Once there, it can also come into contact with the intermediate member 3 or a lower edge of the intermediate member 3 in order to push it upwards, at the same time the actuator 4 is pulled upwards, so that the Mattertotddlingposition is reached again.
- the assembly of the shaft construction according to the invention is as follows: First, a bushing 11 is pressed on one side of the hollow shaft 1, and that on the outer edge, which also serves for the rotationally fixed arrangement of a clamping arm 17. Between the two edges and the lever arm 2 each cylindrical bearing surfaces are provided for connection to the housing of the clamping device.
- the spring element 9 which is preferably designed as a helical compression spring, is plugged onto the inner shaft 6 and inserted into the hollow shaft 1, which is still socket-free on one side.
- the pin member 7 is guided by the slotted guide 8 and screwed into a corresponding threaded bore on the inner shaft 6.
- a bushing 11 is still pressed on the previously bush-free side of the hollow shaft 1.
- the hand lever 5 can be secured rotationally fixed to the inner shaft 6 on one of the two sides.

Zu Beginnn der Drehbewegung ist das Zapfenelement 7 aufgrund der Kraft des Federelements 9 im parallel zur Hauptachsrichtung der Hohlwelle 1 orientierten Führungsabschnitt 14 fixiert. Erst in dem Moment, wenn eine weitere Drehbewegung des Handhebels 5 (aufgrund der Kniehebelmechanik) nicht mehr ausreichend ist, um das Stellglied 4 weiter nach oben zu bewegen, muss die Kraft des Federelements 9 überwunden werden, damit das Zapfenelement 9 in den quer zur Hauptachsrichtung der Hohlwelle 1 orientierten Führungsabschnitt 15 gelangen kann. Dort angekommen, kann es auch in Kontakt mit dem Zwischenglied 3 bzw. einer Unterkante des Zwischengliedes 3 treten, um dieses nach oben zu drücken, wobei gleichzeitig auch das Stellglied 4 nach oben gezogen wird, so dass die Übertotpunktposition wieder erreicht ist.To close the clamping device again or to bring in over-center position, the
