Definitions

  • the present invention relates to attachment clamping jaws for a clamping device for clamping workpieces according to claim 1.
  • clamping devices In the CNC machining of workpieces often clamping devices must be used, with which a variety of possible shapes and sizes of workpieces can be clamped and machined.
  • the requirements of such clamping devices are therefore such that they should on the one hand provide the best possible accessibility for the processing tools, but on the other hand also guarantee a very stable and secure clamping.
  • These two requirements are often in a certain contradiction, because only a small clamping surface for the clamping of the workpiece to be machined is available, but the holding forces must be large and permanent deformations caused by the clamping device itself, if possible to be avoided.
  • clamping devices are often used with interchangeable essay jaws.
  • tensioning devices are the center tensioners from Hemo horrbau, which can be seen from the sales prospectus ZS / d3 / 4000/06/06 of Hemo horrbau.
  • the replaceable top jaws allow adaptation to different workpieces and workpiece sizes, for example by means of different jaw heights, baking hardnesses, jaw corrugations etc.
  • the solution is that the clamping action of the clamping jaws of a clamping device with an effective in the vicinity of the clamping surfaces clamping screw is tightened after clamping the workpiece to be machined in the clamping device.
  • the starting point is the consideration that with common clamping devices, the clamping axis, via which the clamping force is transmitted, but relatively far away from the clamping surfaces, between which the workpiece is actually clamped and held. Thus, even relatively high forces in the clamping axis at the destination, namely between the clamping surfaces, only partially effective.
  • clamping surfaces of the top clamping jaws are additionally provided with "micro-teeth" in order to achieve not only the frictional connection but also a form fit for the clamping. Because of the small size of these micro teeth impression marks remain low and are therefore often not disturbing.
  • the Fig. 1 shows a clamping device 1 with essay clamping jaws 2a, 2b in a three-dimensional view.
  • the top jaws 2a, 2b sit on supports 3a, 3b, which in turn are displaceable by means of a tensioning drive 4 relative to each other in a clamping direction S. It does not matter whether both or only one of the attachment jaws performs the clamping stroke.
  • the attachment jaws 2a, 2b are interchangeable, for example by means of screw, on the supports 3a, 3b fastened.
  • the attachment is done here by screws in recesses 5.
  • spacers 6 may be provided.
  • a workpiece (not shown) can thus be clamped for machining between the first attachment jaw 2a and the opposite second attachment jaw 2b. This clamping takes place via the tensioning drive 4.
  • Each of the two top jaws 2a, 2b has a workpiece support 7, which in turn in the Fig. 2 (Detail A) is shown in more detail.
  • the workpiece support 7 consists of a support surface 8 and a clamping surface 9. The workpiece is placed on the support surface. 8 placed on it and it is pressed together during clamping of the plane-parallel clamping surfaces 9 and held.
  • the first attachment jaw 2a has adjacent to the workpiece support 7 a first hole 10a for receiving a clamping screw 11.
  • the second attachment jaw 2b has adjacent to the workpiece support 7, a second hole 10b for receiving the clamping screw 11.
  • the first attachment jaw 2a is connected to the second attachment jaw 2b via the first and the second hole 10a, 10b in the clamping direction S with the clamping screw 11 connectable.
  • the clamping screw 11 is thus the first essay clamping jaw 2a with the second essay clamping jaw additionally clamped.
  • bracing means that in addition to the clamping action, which is applied by the clamping drive 4, on the clamping screw 11, a further, in the vicinity of the clamping effective expectant clamping force can be applied.
  • the term "adjacent" is thus to be understood in this sense.
  • the tightening screw (as shown) to be an ordinary hexagon socket screw while the first hole 10a has a matching internal thread and the second hole 10b is merely a through hole.
  • the Fig. 2 shows a detail A of a workpiece support 7 of the attachment clamping jaw 2a, in particular in the region of the clamping surface 9.
  • the clamping surface 9 may be provided with so-called "micro teeth” 12. These are used for the positive retention of the workpiece in the clamping device 1.
  • the term "micro-teeth” is used here in a general form, since it may include a variety of possible concrete formations. In the present example, it is projecting, elongated, prismatic structures whose tooth height are adapted to the requirements of the workpiece material.
  • the micro-teeth 12 may be arranged in different directions as shown. So you can also be arranged alternately in the horizontal and vertical directions. Other arrangements and patterns are of course also possible.
  • the Fig. 3 finally shows the clamping device according to Fig. 1 in a side view. It can also be seen that there is good accessibility to the clamping screw 11 in the construction shown.
  • inventive essay clamping jaws 2a, 2b thus make a very easy to handling and with very reliable effect associated improvement in fixtures.
  • the illustrated embodiment of the tensioning device 1 - because of the symmetrical structure of the tensioning drive 4 - is a center tensioning device.
  • the applications of the invention are not limited to center tension devices.
