Definitions

  • the invention relates to a push rod clamping device according to the preamble of patent claim 1.
  • Such push rod tensioning devices are after the DE-STA-CO brochure from July 2003, page 4.7 and after the US 3,912,251 known.
  • Such tensioning devices have a simple structure insofar as they consist of an axial guide for a thrust rail projecting at both ends of the thrust rod, wherein between the spannkraftaufbring brieflyen end of the push rod and a thereto arranged at a distance abutment a toggle mechanism is articulated.
  • the axial guide for the push rod and the associated, arranged at a distance abutment for articulation of the toggle mechanism are summarized from correspondingly solid sheet to a holder.
  • clamping or adjusting mechanism for the push rod toggle mechanisms are provided in both cases.
  • the invention has for its object to improve a push rod clamping device of the type mentioned in terms of their variability.
  • designed as a boom connecting element is arranged on the axial guide with its longitudinal extent parallel to the push rod extension and provided with the coaxial with the push rod extension disposed abutment, between which and the push rod, the toggle joint is articulated. So if the clamping position of the push rod, ie, the workpiece side protruding from the axial guide part of the push rod from small to large or vice versa, so only the fixation of the boom to solve, adjust the boom in the other position and set again.
  • the abutment is formed fastened in different positions on the connecting element. This also results in each case different end positions of the push rod.
  • the toggle mechanism is connected at different points with the push rod, this leads, based on the clamping position, to a shorter protruding from the axial guide part of the push rod and at the other, located at the very end of the push rod body, to a more outstanding Part of the push rod.
  • US 4,257,583 is a push rod clamping device of a special kind is known in which although a stroke adjustment is provided, but which serves a completely different purpose and that of a Feinstein ein a clamping jaw with respect to an opposing clamping jaw.
  • the push rod tensioning device according to US 4,257,583 in fact, in contrast to that mentioned in the opening paragraph US 3,912,251 one behind the other two cooperating tensioning or toggle mechanisms, of which the push rod side serves to the push rod with her jaw by hand only Once in abutment position to bring the workpiece and coupled with an actuating cylinder second, to apply the actual clamping force.
  • the second toggle mechanism operable by the actuating cylinder is provided with fine adjustment elements which consist of a threaded pin which can be fixed at the end of a housing arranged on the axial guide by means of lock nuts and thus can be fine adjusted.
  • the threaded pin extends coaxially aligned with the push rod, ie, the push rod with its axial guide, the double toggle mechanisms and the threaded pins are arranged one behind the other and require a correspondingly long, the actual axial extension of the housing, taking into account that in this device because of only intended fine adjustment only minimal axial adjustments of the threaded pin come into consideration.
  • this labile double system requires the assignment of stops for the two toggle mechanisms in order to bring it at all in an extended position and for effective clamping force transmission can. Unless one is an even more extreme extension of the per se long housing in the clamping device after the US 4,257,583 wants to take into account, this fixture is not suitable for making adaptable to different strengths to clamped workpieces to make correspondingly large Hubetznein sueden the push rod, apart from that with correspondingly large extension of the threaded pin such centimeter-length adjustments a variety of cumbersome rotations of the two locknuts would require.
  • the attacks mentioned housing having the push rod clamping device according to the invention reduced to a simple, inherently stable and Ausbiegesteifen boom, but in one case is variable in length and formed in at least two positions fixable; and which can remain unchanged in another case, but depending on the connection of the toggle mechanism on the push rod this quasi shortened or prolonged comes into effect.
  • the arrangement of the abutment is varied to the connecting element.
  • the in the FIGS. 1 to 10 illustrated push rod clamping device consists of an axial guide 1 for a push rod 2 having on one side of the axial guide 1 a free exciting 20 and on the other side of the axial guide 1 a spannkraftaufbring Joes end 3, wherein between this end 3 and connected to the axial guide 1 abutment 5 is a lockable and openable position, from two articulated actuators 6 ', 6''formed toggle mechanism 6 is arranged.
  • a push rod clamping device in which between the axial guide 1 and the abutment 5 of the toggle lever mechanism 6 designed as a boom connecting element 4 is arranged as the distance producing component, based on the clamping position of the toggle mechanism 6, these in their distance to End 3 of the push rod 2 is formed positionable in different positions.
  • the preferably extended in its longitudinal extent parallel to the push rod cantilever is adjustable in length adjustable and fixable.
  • FIG. 1 shows the push rod clamping device with the push rod 2 in the retracted position.
  • FIG. 2 shows the same device in clamping position, so that the toggle mechanism 6 has been pressed in the extended position or in the over-center position by means of an actuator 6 "of the toggle mechanism 6 arranged lever 9.
  • the set thereby stroke is denoted by H and provides the achievable with this device Maximalhub dar.
  • the connecting element 4 is preferably formed from a first and a second part, wherein the first part is formed as a retaining extension 11 and fixed to the axial guide 1.
  • the first part is formed as a retaining extension 11 and fixed to the axial guide 1.
  • a longitudinal slot guide 12 and to this form-fitting fixing elements 13 are provided.
  • the holding extension 11 has a plurality of fixing element receptacles 16 arranged in series.
  • the cantilever can also be formed from two spaced-apart parallel strands or, because of its stability to be demanded, even more advantageously be formed as a U-profile, which is open to the push rod 2 in a suitable manner on the axial guide 1 or on the housing G in the sense of FIG FIG. 1 or stationary in the sense of FIG. 5 to attach.
  • the toggle mechanism 6 may also be coupled to a pneumatically, hydraulically or electrically actuated pivotally mounted actuator 10, which in FIG. 5 for the sake of simplicity is schematically indicated, although it is a special and of the vorerläuterten contrasting embodiment, which will be described in more detail below.
  • FIGS. 5 to 8 likewise the Hubassinverstell so, as described above, achieved in that the spannkraftaufbring workede end 3 of the push rod 2, which is expedient anyway anyway not cylindrical because of the connection of the actuator 6 'of the toggle mechanism 6, to the stroke adjustment with at least two, as shown, articulation points 8, 8 'is provided for the tensioning mechanism 6.
  • the boom 4, as in FIG. 6 illustrated directly and immovably connected to the axial guide 1.
  • the FIGS. 5 and 6 illustrate the connection to the Anlenkstelle 8 and the FIGS. 7 and 8 the connection to the other articulation point 8 ', wherein the FIGS. 6 and 8 respectively correspond to the clamping positions.
  • the articulation of the actuator 6 'at the articulation point 8' is thus virtually equal to a shortening of the push rod 2, which in turn means that the workpiece-side part of the push rod 2 protrudes less in the clamping position from the axial guide 1.
  • the arrangement or design of the abutment 5 on the non-adjustable boom 4 is to be made or designed so that the remaining length of the end 3 of the push rod 2 with the articulation point 8 with respect to the abutment 5 finds enough space in the provision.
  • a adjustability of the abutment 5 on the boom 4 in the sense of FIG. 10 or the length adjustability of the boom 4 are taken into consideration.
  • the different strokes of the push rod 2 arise automatically when the toggle mechanism 6 reaches its clamping position, ie, when, for example, the actuators 6 ', 6 "have taken their extended position or over-center position.
  • an end stop for the open position of the device is not absolutely necessary, but is preferred in this respect a training to the effect that the axial guide 1 is provided with a retraction position of the push rod 2 defining stop 14 for a arranged on the push rod 2 push rod stop 15.
  • the stop 14, which may advantageously be designed adjustable, is in the Figure 1 to 4 indicated as a small line and the push rod stopper 15 as a small cross.
  • axial guide 1 is provided with a parallel to the push rod 2 slot guide 18 for the push rod stop 15, whose force introduction side end forms the stop 14 for the push rod stop 15, which in the plan view according to FIG. 9 something more clearly illustrated.
  • the abutment 5 has, on the one hand, an axis of rotation of the toggle lever mechanism 6 and, on the other hand, fixing elements for attachment to the connecting element 4.
