Definitions
- the invention relates to a clamping device for clamping of workpieces consisting of a head piece with a Swivel-mounted tension arm, which is operated by an adjusting mechanism is connected to a drive actuator, wherein on Head piece on the arm and on the back recesses for fastening the device are arranged on a device carrier.
- the invention is accordingly based on the object of clamping devices of the type mentioned in this regard and improve their headers in terms of their attachability are more variable on carriers.
- This task is based on the fixtures of the beginning mentioned type according to the invention in that the recesses arranged in the lower part of the head piece their height essentially the length of the lower head part correspond and that in at least one of the recesses a connecting plate interchangeably used and this in turn is provided with connection recesses.
- connection plates Apart from special arrangements and designs of the connection recesses in the connection plates, which is so practical represent variable connection adapters for special carriers an advantageous development in that at least one of the connection plates on the connection side towards the head piece Fasteners for end position query elements and more provided with connections for position signal transmission lines is. With these designs, the connection plates are advantageous at the same time as easily replaceable Holder for end position query elements with exploited and represent another element to increase variability for represent such jigs.
- the tensioning device still exists and is known Way from a head piece 1 with a pivotally mounted thereon Tension arm 2, which has an actuating mechanism M with a drive actuator 3 is connected, with 1 Recess arm and rear recesses 4 for attaching the Device are arranged on a device carrier VT.
- a clamping device is now with reference to the Fig. 1-4 and regardless of whether it is in the headers around fork-shaped (Fig. 3) or "closed" (Fig. 1, 2, 4) with laterally attached clamping arm 2 is essential that the im lower part of the head piece 1 arranged recesses 4 with their height H essentially the length L of the lower head part 1 'and that in at least one of the recesses 4 a connecting plate 5 interchangeably used and this in turn is provided with connection recesses 6.
- each is the recesses 4 on the head piece with a connecting plate 5 provided, as shown in Fig. 3, with screw connections 11 are fixed to the head piece 1 and in turn Have screw receptacles 12 to the device on To be able to determine device carrier VT, which is only in FIG. 1 is indicated by dashed lines.
- connection plates 5 What range of variation with regard to the connection options result from the connection plates 5, is shown in Fig. 3, the two identical connection plates 5 in Fig. 3A on Headpiece 1 shows.
- Fig. 3B shows a connector plate in reverse Allocation to head piece 1 or to the recess 4, which in this assignment leads to the distance D between the upper edge of the device carrier VT and the lower edge of the UK Tension arm 2 (see Fig. 2) becomes correspondingly smaller.
- Figure 3C illustrates that the recess 6 in height H 'and, for example. compared to the recess 6 in Fig. 3B also larger can be.
- connection plates 5 on the connection side to the head piece 1 Fasteners 7 for end position query elements 8 and also with connections for position signal line 10 Mistake are advantageous and with reference to FIGS. 1, 2 the connection plates 5 on the connection side to the head piece 1 Fasteners 7 for end position query elements 8 and also with connections for position signal line 10 Mistake.
- connection plates 5 with fasteners 7 for such sensors the mounting problem of such sensors is also with solved, and also variable, namely in that that with rear attachment to the device carrier VT (according to Fig. 1) the end position query elements on the clamping arm side Connection plate 5 can be arranged or the whole thing vice versa, which should not exclude the end position query elements 8 also to be arranged on the connection plate 5, which the Establishes connection to the device carrier VT.
- the arrangement of the sensors on the connection plate 5 provided that no support or Holding function for the device has to take over, as a result easy interchangeability of the sensors or their positioning to each other, even if the carrier remains on site Clamping device can be made.
- connection plates 5 should be provided with a connection recess 6 that in such a case the opposite recess 4 on the head piece 1 with a corresponding "connection plate "5 is equipped, but it does not have to have a connection recess 6.

Abstract
Description
- Fig. 1
- im Schnitt das Kopfstück einer Spannvorrichtung mit induktiver Endstellungsabfrage;
- Fig. 2
- einen entsprechenden Schnitt mit pneumatischer Endstellungsabfrage;
- Fig.3A-C
- schematisch und perspektivisch eine gabelförmiges Kopfstück mit den eingesetzten Anschlußplatten und
- Fig. 4
- in Rückansicht ein als Hohlkörper ausgebildetes Kopfstück.
Abschließend und im Gegensatz zu den dargestellten Ausführungsbeispielen sei unter Bezug auf die Maßgabe, daß mindestens eine der Anschlußplatten 5 mit einer Anschlußausnehmung 6 versehen sein soll, darauf hingewiesen, daß in einem solchen Fall die jeweils gegenüberliegende Ausnehmung 4 am Kopfstück 1 mit einer entsprechenden "Anschlußplatte" 5 bestückt wird, die aber keine Anschlußausnehmung 6 aufweisen muß.
