Definitions

  • the invention relates to an actuating gear for installation in head pieces or housings of toggle clamps, consisting of a first, linearly guided, by a drive actuatable actuator, an articulated thereon Intermediate link, a second rotatably mounted, with the actuator articulated for the attachment of a tension arm, which consists of two one Gap enclosing circular disks is formed that through a central, penetrating first gap Shaft piece and a second eccentrically arranged Shaft piece are firmly but releasably connected.
  • actuating gear known in the headpiece and drive are separable, but also with this actuating gear the entire load is in the tensioned position transferred to the housing, although for the Support of the linear actuator in the upper housing area a special abutment (roller bearing) is arranged.
  • the object of the invention is based on an actuating gear of the type mentioned in the introduction, to improve this in that the tension forces occurring essentially from the transmission itself recorded, i.e., differentially distributed and thus passed on reduced to the housing or head piece are seen so that from the load side.
  • the housing design gives greater freedom, one but always on the same actuation gear can fall back.
  • gap used in claim 1 is not a space between the panes to understand from just a millimeter width or even a gap, how it would result if the two circular disks lie directly next to each other, but the gap width is dimensioned so that at least the essential here Extension of the linear actuator between the circular disks can intervene, who in turn is in strength at the Orient the load to be absorbed during the clamping process is.
  • the extension takes over the whole via the clamping arm and intermediate element in the linear actuator Tension load and is based on the first, central shaft section, i.e. the load remains in a way in the transmission and is differentially on the Circumference of the circular disks distributed over the head piece or Broadcast case, however this, apart from the Bearing openings for the two circular disks, otherwise designed may be.
  • Such a “circular disc bearing” in the housing has also the tensioning device according to the aforementioned US-A-5 171 001, but this is the rotating actuator for the tension arm Circular discs, but around a cylindrical rotating body with engagement groove for the pontic and that Linear actuator which, like with tensioners common, with an attached slider in Housing is guided and supported. Apart from that, can the clamping arm is only attached to the outside of the rotating body become. In contrast to this and thanks to the clamping load absorption by extension and central first shaft piece needs the actuating gear according to the invention no such back support.
  • the tension arm does not have to necessarily placed on the outside of one of the circular disks be, but there is also the possibility of what else is explained in more detail, the clamping arm between the circular discs to be arranged, i.e. the clamping arm would then be centric protrude from the gearbox.
  • the actuating gear for installation in head pieces from Toggle clamps exist, with reference to Fig. 1 to 4, as before and basically from one first, linearly stirred, actuated by a drive A.
  • Actuator 1 an intermediate element 2 articulated thereon, a second rotatably mounted, with the intermediate member 2nd articulated actuator 3 for attaching a Clamping arm 4, which includes a gap 5 from two Circular disks 3 'is formed by a Central, first shaft piece passing through the gap 5 6 and an eccentrically arranged second shaft piece 7 are firmly but releasably connected to one another, an extension 9 with which in the gap 5 next to the engaging first shaft piece 6 and by Intermediate member 2 connected to the second shaft piece 7 Actuator 1 is provided, and one in the extension 9 provided slot open towards the first shaft piece 6 8, whose width B is the diameter D of the first Corresponds to shaft piece 6 and its longitudinal center line 10 intersects the axis 6 'of the first shaft piece 6, wherein the extension 9 with its inner flank 9 'in the
  • Both for drive A (see Fig. 6) and for Actuator 1 belonging to actuator 1 does not necessarily have to as shown, with its axis that of the central first Cut shaft piece 6, but can also be arranged be that their axis with the line of motion G of the Cross bolt 2 '' coincides.
  • the embodiment shown in this regard is preferred, because it concentrates the whole gear Drive A (e.g. pneumatic cylinder) is assigned and the Parts far from the clamping arm, i.e. the one to the right of the first Part of the actuator 3 located on the shaft piece 6 for still advantageous further developments to be explained remains free.
  • gear Drive A e.g. pneumatic cylinder
  • the load is now no longer on the right side (based on the illustrations) of the actuator 1 during the actual tensioning process, as described above, but rather through the inner flank 9 'of the extension 9 on the actuator 1, which attaches itself to the first shaft piece 6, which is connected in a suitable and easy to install fixed but releasable manner to the two circular disks 3 '(see FIG. 4), which distribute the load to the head piece K differentially over the entire circumference of which an embodiment is shown in Fig. 7.
  • the head piece K could be reduced to a shape that was "emaciated" in FIG. 6 A, B, without having to change anything on the actuating gear, only a through opening 16 for the actuator 1 would have to be provided in the flange part AT.
  • the transmission also has training in that this the tension arm 4, as schematically in FIG. 5 shown, is assigned in the middle, with the disc side End of the tension arm 4 'bswp. fork-like is formed and the legs 4 'the shaft piece 6 reach around. From the outer flanks of the circular disks 3 ' are then the legs 4 'with these firmly by screws connected.
  • Another advantageous training consists of the following:
  • the distance H of the articulation axis 2 'of the intermediate member 2 is on the actuator 1 to the lower edge 1 '' of the extension 9 larger dimensioned as the maximum stroke of actuator 1, i.e. the total height of the actuator is not insignificant larger than usual attachments on adjusting rods Linking the pontic 2.
  • Such a design offers advantageous further training opportunities than on the one hand in the lower (drive side) area of the first actuator 1 in one side flank lower (drive side) surface of the actuator 1 down open adjusting groove 13 can be arranged and as for others comfortably in the back (pontic side), load-free part 1 '' 'of actuator 1 Closed position cam 14 adjustable and in one parallel also groove-shaped recess 15 ' adjustable opening angle stop 15 can be arranged can (see Fig. 6 but also Fig. 7).
  • the actuating gear consists of a first, linear guided actuator which can be actuated by a drive A. 101, an articulated link 102, a second rotatably mounted, with the intermediate member 102nd articulated actuator 103 for attachment a clamping arm, which consists of two a gap 105 enclosing circular discs 103 'is formed by two vis-a-vis eccentrically arranged, the gap 105 penetrating shaft pieces 106, 107 firmly together are releasably connected, the one shaft piece 106 the Articulation axis for the intermediate member 102 forms and where furthermore the two circular disks 103 'in FIG the same gap distance arranged, coaxial to each other fixable rings 108 are guided, the gap side parallel to the straight line of extension and movement of the Actuator 101 has a guide groove 109 with a clamping force abutment flank 110.
  • This embodiment is also in itself closed actuating gear, which in itself via Circular disks the clamping load on the rings 108 or whose clamping force abutment flanks 110 and that as self-contained system in head pieces or housings can be installed that is only circular Must have openings for receiving the rings 108. It is even possible to use the entire gearbox, for example to be arranged on one side of a support. That in the embodiment Intermediate member 102 shown in FIG. 10 consists of two tabs 102 'through a shaft piece 106 'are articulated at the end of the actuator 101.
  • the tension load transfer to the two abutment flanks 110 of the rings 108 takes place, for example, through the outside next to the tabs 102 'placed on the shaft piece 106' Ball bearing 111.
