Definitions

  • the invention relates to a clamping device according to the preamble of claim 1
  • a tensioning device of the type mentioned is according to the DE 197 51 950 C1.
  • This consists of a linearly movable Drive element (pneumatic cylinder), which is for actuation from at least one clamping tool (clamping arm) via a in a housing arranged adjusting mechanism (toggle mechanism) operatively connected to a pivotally mounted in the housing pivot axis is.
  • adjusting mechanism toggle mechanism
  • On the housing is a pivot bearing areas on both sides (Radial and thrust bearing) provided for the pivot axis, between which the toggle mechanism is arranged.
  • the pivot axis is to attach the clamping arm via a Pivot bearing area formed protruding.
  • the invention is based on the object at a clamping device of the type mentioned the effort to retrofit with respect to the arrangement of the pivot axis on constructive possible easy way to reduce.
  • the pivot axis from a hollow shaft and one concentric in this and too this rotationally fixed output shaft is formed, wherein the hollow shaft (approximately) formed housing wide and in the Rotary bearing areas is rotatably mounted and wherein the output shaft axially displaceable to the hollow shaft, but at this is formed fixable.
  • the pivot axis according to the invention in contrast to the beginning described axis according to DE 197 51 950 C1 at least two parts formed, wherein the connected to the adjusting mechanism Part in principle as rotatably arranged in the housing hollow shaft and the other part as in the hollow shaft against rotation, but is formed axially displaceable and fixable.
  • the hollow shaft has approximately the width of the housing.
  • the output shaft preferably has a Width on which it allows, on the one hand with one-sided Projection a clamping arm and on the other hand with bilateral Supernatant, for example, a fork-shaped clamping arm to it Fasten.
  • the output shaft can be longer or longer possibly also be shorter. It is crucial that for modification only the output shaft optionally replaced or even be moved in its axial position got to.
  • Both said and the inventive clamping device have a drive element 1.
  • the drive element 1 as an electric drive educated.
  • linear movable pneumatic see the cited DE 197 51 950 C1
  • hydraulic drives or a manual drive, and although depending on the application and purpose.
  • the drive element 1 is for actuating at least one Clamping tool 5 via a arranged in a housing 2 Adjusting mechanism 3 with at least one rotatably mounted in the housing 2 Swivel axis 4 operatively connected.
  • the clamping tool 5 is in the illustrated embodiment designed as a swivel or clamping arm. Alternatively, though also training as push rod, centering or underfloor tensioner possible.
  • the adjusting mechanism 3 is in the illustrated embodiment designed as a toggle mechanism.
  • the tensioning device according to the invention but just as well with a so-called curve mechanics be equipped, as for example in the EP 0 747 172 A1.
  • housing 2 of the invention Clamping device of two in any case approximately mirror-symmetrical to each other Shells is formed.
  • Figure 2 only the left shell shown, while the right shell disassembled is to provide insight into the interior of the jig.
  • the pivot bearing area 6, 7 are especially as radial bearings, but also as Thrust bearing, for example, for a shaft shoulder 20 at the Pivot axis 5 or the still to be explained according to the invention Hollow shaft 8 is formed.
  • bearing types or types come in particular ball, roller or sliding bearing into consideration.
  • the Clamping device according to the figures 1 to 12 has a Slide bearing trained, combined radial-axial bearing.
  • a clamping tool 5 for example, the one shown in Figure 1 Clamping arm
  • this is at least over a pivot bearing area 6, 7 protruding formed (in Figure 2 projects the pivot axis 4 via both pivot bearing area 6, 7 addition, so that at both pivot axis ends a clamping tool 5 can be arranged.
  • the one-piece according to the prior art Swivel axle 4 now form two parts, depending on Arrangement of the clamping tool 5 without major retooling the Pivot axis 4 optimally placed.
  • adjusting lever 10 For actuating the now two-part pivot axis 4, As can be seen in particular from FIG. 3, on the hollow shaft 8 an operatively connected to the adjusting mechanism 3 adjusting lever 10 is arranged.
  • This lever is a drag member 18 with the actuator 19 of the drive element 1 operatively connected, d. H. a linear movement of the actuator 19 results in a known Way to a rotational movement of the pivot axis 4 and the hollow shaft 8th.
  • pivot axis 4 also has the hollow shaft 8 for their storage in the housing 2 preferably at least at the pivot bearing areas 6, 7 a size adapted to these, cylindrical outer contour on, d. H. is in these places they, as shown for example in Figure 6, in the above stored described radial-axial bearings.
  • a wave shoulder 20 on the hollow shaft is supported on both sides of the bearings from.
  • the hollow shaft 8 (see FIG 3) a quadrangular (square) inner cross-sectional contour on. Suitable fitting is advantageously provided that the output shaft 9 has a square outer cross-sectional contour.
  • General - ie in each case to the specific application adapted - is provided that the two to each other in Form fit to be brought contours at least triangular or are polygonal.
  • the hollow shaft 8 in the axial direction of two hollow shaft sections 11, 12 is formed, preferably by means of the pins 21 shown in Figure 11 against rotation with each other are connected and approximately in the center of the building 2 together Connection stand (see in particular the dividing line in FIG 6).
  • the output shaft 9 is advantageously provided that on the inside of the hollow shaft 8 at least one recess 13 is arranged; but preferably several wells in the form of an axial grid, d. H. the output shaft 9 is, as shown in Figures 6 to 10, at various Relative positions to the hollow shaft 8 can be positioned and fixed.
  • Output shaft side is demenst Schemeend provided that the Output shaft 9 has a fastening mechanism 14.
  • This preferably has at least one on the output shaft 9 arranged with the recess on the hollow shaft 8 in positive engagement engageable locking element 15, wherein this vorzugs- and formed, for example, as at least one ball is in the latching position in the preferably spherical segment-shaped Recesses 14 engages.
  • Adjustment element 16 is arranged, which with the Verrastungselement 15 is operatively connected and at axial adjustment a Radial adjustment of the locking element 15 causes.
  • the Adjustment element 16 is preferably helical and in a provided on the output shaft 9 threaded hole 17 arranged, wherein the latching element side End of the helical adjusting element 16 conical and is operatively connected to the latching element 15.
