Definitions

  • the invention relates to a clamping device according to the preamble of the main claim and is intended for clamping workpieces on documents adapted therefor.
  • Such clamping devices are well known and in use, so that no special printed evidence is required in this regard. Since it is of interest to be able to interrogate the end positions of the tensioning arm, e.g. the closing and opening position, for example for corresponding command transmission to the processing machine, it is also known to equip such tensioning devices with end position transmitters and end position sensors, for which different ones Possibilities exist and are known. It is thus possible to arrange an end position sensor on the piston rod moving up and down and to compare it with end position sensors in the area of the head piece, which must therefore be passed when the piston rod moves to the end position sensor (DE-A-34 03 961).
  • Variants consist of arranging a master linkage on the piston rod and parallel to it, whereby depending on the length of this linkage the end position sensors can be arranged on the head piece or even in the area of the actuating cylinder (DE-U-88 04 990).
  • actuating cylinder DE-U-88 04 990
  • the invention is therefore based on the object to improve a tensioning device of the type mentioned and form that the end position tap can be made directly or almost directly on the element to be pivoted, ie, the tension arm itself.
  • This inventive design of the tensioning device advantageously makes it possible to query the end positions directly on the tension arm or on the axis supporting them and to arrange the end position sensors and sensors directly in this area, ie on the head piece, which also has the additional advantage of easy accessibility in this Area has.
  • the sensors for example, the following can be considered: microswitches or mechanical, electrical, pneumatic, opto-electronic sensors.
  • an advantageous further development consists in that the ends of the axis with the end position sensors arranged thereon are at least partially arranged in recesses in the fork parts of the head piece.
  • the end position sensors and / or the end position transmitters are arranged on the head piece in an adjustable manner.
  • the length of the axis can advantageously be dimensioned in accordance with the width of the head piece, so that the axis end faces run in the planes of the head piece side faces, i.e. if the position sensors are not used, the axle ends do not protrude over the flanks of the head piece.
  • the end position sensors cannot be arranged on but in the fork parts of the head piece. This is possible in particular if the fork parts have a sufficient material thickness.
  • these sensors on the tensioning arm side are inserted from above or below into corresponding bores which extend parallel to the course of the piston rod and are directed towards the end position sensors also located in this area. which then have to be arranged in a corresponding orientation on the axis firmly connected to the tension arm.
  • Such an arrangement would of course benefit from a particularly narrow overall width of the tensioning device. Irrespective of this, it is also readily possible to arrange the end position sensors in holders on the side faces of the head pieces.
  • the clamping device consists of a fork-like head piece 1, on which the clamping arm 4, which can be actuated by the piston rod 2 of an actuating cylinder 3, is pivotably mounted on an axis 5 and on which end position sensors 6 are also arranged, in the area of which the position sensors are located. It is essential for such a tensioning device that the tensioning arm 4 is firmly connected to the axis and on the ends 7 of the axis 5, which are free with respect to the head piece 1, 5 end position sensors 8 and in the adjustment range of which the two end position sensors 6 are arranged.
  • the design of the end position sensors 8 naturally depends on the type of end position sensors 6 used, which ultimately can also be optical sensors, for example. However, the use of microswitches or proximity switches for this is also possible. In the exemplary embodiment shown, the end position sensors 8 are simply designed as switching cams fixedly arranged on the axis 5, which thus influence the sensors 6 by mechanical influence.
  • the length L of the axis 5 is dimensioned accordingly to the width B of the head piece 1, and the axis end faces 7 'of the axis 7 are arranged to run in the planes of the head piece side faces 10.
  • the end position sensors 6 are arranged in holders or clamp holders 11 on the head piece side surfaces 10, which are shown in a side view according to FIGS. 1 and 2. If a sufficient material thickness is available on the fork parts 1 ', 1'', the sensors could also be easily arranged in bores 13, as indicated by dash-dotted lines in FIG. 1, or pockets, which then only another position of the switching cams or the position transmitter 8 at the ends 7 of the axis 5 required.
  • an end position detection would then be possible directly on the tension arm or on its articular extension 14, which, as shown for example, is provided with two position transmitters 8 'offset by the pivoting movement to be taken into account.
  • the sensors 8 ' can also be arranged offset from one another in the direction of the axis 5 on the extension 14.
  • the arrangement of the sensors 6 then only has to be oriented to that of the sensors 8, ie, depending on the arrangement possibility and external dimensions of the sensors, these can be arranged one behind the other or next to one another.
