Definitions

  • the invention relates to a clamping device for clamping workpieces, according to the preamble of the independent claim. 1
  • Such clamping devices are well known and in use, so that it does not require any documentary proof. Only, for example, should be noted therefore on DE-U-92 15 151.5 and DE-U-94 11 291.6, which have the features of the preamble of claim 1.
  • the spannarm- and rear recesses on the head so they serve to be able to fix such clamping devices against rotation on correspondingly adapted to these recesses straps.
  • these are frame-type racks in which, for example, bodies or body parts are releasably tightened to provide such workpieces, i. in particular, to be able to make precise welds.
  • the matching hole pattern on the head and on the intermediate piece thereby allow different position assignments of the clamping device to the carrier, which is otherwise an angled workpiece support, between the and an angled clamping arm in the direction of device longitudinal axis linearly oriented clamping force a workpiece is clamped
  • An equipment of a clamping device with a workpiece support is also in the articles of DE-A-29513131, wherein in some parallel in one case, the workpiece support is fastened in a similar manner as in US-A-3,545,050 between the side plates of the head piece , or in another case by lateral screwing on a laterally projecting extension of the head piece or by screwing a fastened in a Kopf Glaaus Principleung by means of a flange carrier also for a workpiece support.
  • the invention is accordingly based on the object to design and improve clamping devices of the type mentioned in that their headers are variable with respect to their attachability to carriers.
  • the term "in the lower part of the head piece” is to be understood as meaning the region which extends approximately below the tensioning arm bearing as far as the connecting region of the drive member (usually pneumatic cylinder).
  • the manufacturer of such jigs is enabled by this inventive design of the jig headgear to produce completely independent of required recess sizes and arrangements the same head pieces for fixtures of certain types and sizes, then satisfies the respective actual positioning requirements and specific carrier dimensions by appropriate design of the actual terminal plates becomes.
  • connection plates which thus represent practically variable connection adapter for special carriers
  • at least one of the connection plates is provided on the connection side to the head with fasteners for End einsabfrage implant and also with connections for Stellungssignalgabe Oberen.
  • the terminal plates are advantageous at the same time as far as also easily replaceable holder for End einsabfragimplantation exploited and thus represent another variabilticianser Worndes element for such fixtures.
  • the tensioning device is still and in a known manner from a head piece 1 with a pivotally mounted thereto clamping arm 2, which is connected via an actuating mechanism M with a drive actuator 3 in connection, wherein the head piece 1 spannarm- and recesses 4 for mounting the device a device carrier VT are arranged.
  • each of the recesses 4 present on the head piece is provided with a connection plate 5, which, as shown in Fig. 3, fixed with screws 11 on the head piece 1 and in turn have Verschraubungstreatmentn 12 to set the device on the device carrier VT to be able to, which is indicated by dashed lines only in Fig. 1.
  • FIG. 3 shows two identical connection plates 5 in FIG. 3A on the head piece 1.
  • Fig. 3B shows a connection plate in reverse assignment possibility to the head piece 1 and the recess 4, which leads to this assignment that the distance D between the upper edge device carrier VT and lower edge UK clamping arm 2 (see Fig. 2) is correspondingly smaller.
  • Fig. 3C illustrates that the recess 6 in its height H 'and, for example. In comparison to the recess 6 in Fig. 3B may be sized larger.
  • connection design of a device carrier VT this can also be used directly in the recesses 4 and the device attached to it and fixed.
  • connection plates 5 is provided on the connection side to the head piece 1 with fastening elements 7 for end position sensing elements 8 and also with connections for position signal transmission lines 10.
  • this takes account of the fact that today usually End einsabfrageIAN for the two end positions (closing and opening position) of the clamping arm 2 are required for such but on the other hand on "normal" headers special measures for attaching appropriate, from a donor G on the linear actuator LG of the actuating mechanism M influenceable or switchable sensors (Endwolfsabfragemaschine 8) must be made, no matter what kind of sensors it is.
  • the attachment problem of such sensors is also solved, and also variable, namely to the effect that when placed back on the device support VT (as shown in FIG. 1) the End einsabfrage emulate can be arranged on the tension arm side terminal plate 5 or the whole also vice versa, which should not preclude the End einsabfrage implant 8 to be arranged on the terminal plate 5, which establishes the connection to the device carrier VT.
  • the arrangement of the sensors on the connection plate 5 is expediently provided, of course, which does not have to carry any supporting or holding function for the device in the particular case of attachment since this makes it easy to replace the sensors or position them even when the clamping device remains on the support can be.
