Definitions

  • the invention relates to a clamping device for clamping Workpieces according to the preamble of the independent claim 1.
  • Such clamping devices are, for example, according to DE-U-92 15 151.5 known.
  • the invention is accordingly based on the object of a tensioning device of the type mentioned above with regard to their end position interrogation device to train and improve in such a way that they can easily and without auxiliary tools to changed installation conditions, Adjustment paths or operating conditions of the Clamping device is adaptable.
  • This task is on and with a clamping device of the generic type Type solved according to the invention in that the end position interrogation device from one of the end position query elements laterally receiving half-shell and this from at least a head part and a connecting part is formed, head part and connecting part to each other by means of releasable connecting elements can be aligned aligned and with connecting and fixing elements are provided for the head piece of the clamping device.
  • Advantageous further developments and embodiments result according to the subclaims.
  • This training according to the invention is a kind of variable-length carrier for the actual end position query elements created together with these query elements (e.g. microswitches, sensors or the like.) a total in insert the clamping device head piece and position it precisely easily lockable cassette.
  • An embodiment is preferred in which between head and Connection part at least one with corresponding connecting elements provided intermediate part can be used because this Embodiment the greater adaptability to different lengths Offers recesses of clamping devices and the head and Connection parts can always be maintained without change.
  • the manufacturer can restrict himself to one of the two parts with different lengths to produce and keep ready.
  • Fig. 1 the interior view is in principle in a half section a part of a clamping device head piece 10 is shown, with a range of motion in the jig head 10 for a linear actuator that can be actuated by a drive A.
  • LS is designated 27.
  • Such a linear actuator LS moves itself in the direction of arrow 28.
  • a sensor G arranged laterally out of the movement space 27 stands out and explained in more detail below End position query element 2 (here microswitch) actuated.
  • End of the linear actuator LS is (not particularly shown) with coupled to the swivel arm SA in bearing L, the via actuator LS between two end positions (see Fig. 7) is adjustable, which must be queried.
  • an end position interrogation device consists, as shown, for example, of a half-shell 1, which is open to the movement space 27 of the linear actuator LS and to a flat side.
  • an end position sensing device 2 In the interior of the half-shell 1, two end position sensing elements 2 are arranged, which are electrically connected by means of cables 5 to a plug contact 6, which makes the signals of the end position sensing elements 2 accessible.
  • This plug contact 6 is arranged at a rear opening 7 of the half-shell 1.
  • the cables 5 are laid freely in a channel-like area 4, are flexible and thus allow the position of the end position interrogation element 2 to be changed along the direction of movement 28 of the linear actuator LS.
  • the end position query element 2 are held within the half-shell 1 by means of pins, not shown here, arranged on the shell side, which are inserted into the bores 3 of a row of holes in the desired position.
  • each of the two end position sensing elements 2 is laterally fixed by inserting the entire end position sensing device into the recess 9 or 9 'of the clamping device head piece 10, as the edge 8 of the half-shell 1 advantageously lies at the same height as the surface of the end position sensing elements 2 (see Fig. 8). Falling out of the end position interrogation elements 2 from the half-shell 1 is thus reliably prevented by their walls after their insertion into one of the recesses 9, 9 '.
  • the head part 11 and connecting part 13 by means of releasable connecting elements 14, 19; 15, 16 can be connected to one another and with connecting and fixing elements 17,21 to the head piece 10 are provided.
  • the half-shell 1 is constructed modularly from the head part 11, intermediate part / s 12 and connecting part 13.
  • the half-shell 1 is segmented in such a way that the same or different lengths of individual parts 11, 12, 13 result which, when put together, result in a half-shell 1 which can be adapted to the required overall lengths and setting ranges of the end position query elements 2.
  • only a head part 11 and a connection part 13 are joined, these two parts each having the bores 3 for inserting the end position interrogation switch 2.
  • either the head part 11 and the connecting part 13 can be extended, or one or more intermediate parts 12 are inserted between the head part 11 and the connecting part 13, which together with the head part 11 and the connecting part 13 then, according to the required distance, the adjustment path via arrangement of Define end position query elements 2.
  • the head part 11 and the connecting part 13 can always be of the same length and for each application with one or more intermediate parts 12 from a series, differently long intermediate parts 12 can also be fitted together.
  • connection between head part 11, connecting part 13 or intermediate part 12, as shown in FIGS. 4a and 4b by means of pins 14 which are in corresponding bores (not shown) of the adjacent part can be inserted.
  • FIG. 4c or 4b can be a latchable Connection by means of a locking hook 15 and a locking recess 16 can be provided at the neighboring part.
  • a precise adjustment of the end position interrogation device for Linear actuator and its encoder G can be advantageously simple Realize that on the outside and on top of the half shell 1 a rounded cam as a connection and fixing element 17th is arranged, the in the intended plug-in state End position interrogation device in the recess 9 or 9 'in a corresponding recess 18 engages the head 10. This is the exact insertion position of the end position interrogation device always guaranteed safely and without complex adjustment. It goes without saying that in kinematic reversal also a cam 19 in the wall of the recess 9 or 9 ' a corresponding recess of the half-shell 1 can lock.
  • a leaf spring 22 between half shell 1 and wall of recess 9, 9 ' are arranged so that they are fixed in the recess 9, 9' is and with an associated cam as a fixing element 21 on the connecting part 13 of the half-shell 1 in the inserted state locked.
  • such a spring element also be integrally formed on the connecting part 13, wherein the resilient locking part 23 on an edge 24 of the recess 9, 9 ' locked.
  • a stop edge 25 is provided the flank of a common locking groove opposite the edge 24 25 'forms.
  • FIGS. 8A, B which represents a section along line II in FIG. 7, in which the arrangement of the end position interrogation device is only indicated by dashed lines.
  • 8A makes it clear that the actual query elements 2, which are attached to the half-shell 1 consisting of the described individual parts as carriers, are held in their inserted position by the adjacent flank of the head piece 10.
  • FIG. 8B it is advantageously provided, according to FIG. 8B, to assign the half-shell 1 a correspondingly dimensioned spacing plate 1 'on its flank, which in a suitable manner on the one or the other side of the half-shell is connected to it.
