Definitions

  • the invention relates to a clamping device, in particular toggle lever clamping device for clamping workpieces according to the preamble of the main claim.
  • Clamping devices of the type mentioned are well known and in use, so that no special printed evidence is required. Clamping devices of this type are required in order to clamp any workpieces for machining purposes on tables of processing machines, but in particular also to, for example, body parts and the like. Fix the sheets to each other so that they can be welded in the correct position.
  • the actuation of the clamping arms on these devices is usually carried out with actuating cylinders, the pistons of which can be pressurized pneumatically from one side and the other in order to bring the clamping arm into the closed position on the one hand and again into the open position on the other hand.
  • the pressure medium connections are attached to the flanges forming the cylinder ends on both sides, ie in particular the reset pressure medium line extends laterally over the entire length of the actuating cylinder.
  • the same applies i.e. these sensors are located either on the head piece of the device or in the area of the actuating cylinder, with the cable routing also on the side of the devices extend and the cable connector is also arranged transversely to the longitudinal axis of the device.
  • the invention is therefore based on the object to improve tensioning devices of the type mentioned and to design so that the cable connectors and thus the leads leading to this can also be arranged outgoing to the rear.
  • the channel with its two branches is expediently designed as an open groove, the cover serving on the one hand as a carrier for the cable connector and on the other hand as a closure for the groove.
  • this entire sensor device can be arranged both in the head piece and in the area of the actuating cylinder, depending on the structural conditions, the channel or its two branches are preferably arranged in the end flange of the actuating cylinder.
  • the aforementioned cover advantageously consists of a simple sheet metal blank with an angled flag on which the cable connection piece is arranged.
  • the cover is also advantageously designed such that it can be attached in both positions at the same location on the device.
  • the illustrated embodiment is a clamping device of a special type, in which the two sensors, which are arranged at selectable distances from one another, are actuated with an actuating rod which, as can be seen, is fastened in a suitable manner to the upper end of the piston rod 12.
  • the two sensors 11, which is also known, could also be directly in the area the piston rod is arranged on the head piece 13 of the tensioning device.
  • the connecting lines 1 are arranged in a channel 2 of the tensioning device, which has a branch 4 going out laterally and a branch 5 leading to the free end 3 of the device.
  • the cable connector 7 sits on a cover 6, which is so convertible with the cable connector 7 on the device that the cable connector 7 at the end of the side branch 4 or at the end of the other branch 5 of the channel 2 with its branches 4, 5 not as Bore formed, but advantageously in the form of an outwardly open groove 2 ', which is only covered by the cover 6.
  • This cover 6 is formed from a sheet metal blank 6 'in the example shown, which has an angled flag 9, to which the cable connector 7 is attached in a suitable manner and is arranged as can be seen.
  • this sheet metal blank is adapted to the shape of the end flange 3 'of the actuating cylinder 8 and, as can also be seen, only fixed with a small screw at the point 10 of the end flange 3'.
  • the arrangement of this point 10 is such that the sheet metal blank 6 'can also be fixed in the dot-dash position in which the cable connector 7 goes backwards from the end flange 3' of the actuating cylinder 8.
  • Such a channel or groove formation and arrangement could, of course, also be provided at the cylinder-side end of the head piece, insofar as the structural conditions permit.
  • this problem-free changeover option also has the essential advantage that, in the event of an exchange requirement, the entire sensor device, i.e. the sensors 11, the connecting lines 1 and the cable connector 7 can be easily replaced, regardless of whether the cable connector 7 to the side or to the rear of the actuating cylinder or at its end flange 3 'is attached.
