Definitions

  • Clamping device in particular for reversible clamps of CNC vertical machines
  • the invention relates to a clamping device for turning clamps of CNC vertical machines with at least one clamping plate, which is provided with flat-side bores for fastening clamping or intermediate elements, and has bores for its own fastening on the end faces.
  • clamping devices In order to take full advantage of the very expensive NC and CNC machines, clamping devices have been developed that allow several workpieces to be clamped.
  • Conventional clamping devices have a clamping plate or a clamping block, which are provided with grid holes on their clamping surface, by means of which the workpiece holders can be fastened to the clamping plate or to the clamping block.
  • the clamping devices are designed as a single clamping plate, as a T-shaped plate or, as already mentioned, as a prism, but their respective shape cannot be changed. Variations only exist in the different utilization of the grid bores.
  • the object of the invention is to improve a clamping device of the type mentioned at the outset in such a way that it can be increasingly adapted to different requirements with regard to workpiece clamping.
  • Another object of the invention is to provide a simplified clamping device of the type mentioned at the outset, which, however, offers the same or improved clamping options for different workpieces compared to the devices according to the prior art.
  • the tensioning device according to the invention is characterized in that it is designed as a variable kit with two rotatably mounted flange plates which have grid holes, the tensioning plate being clampable in different positions with the flange plates.
  • the kit according to the invention one or more clamping plates can be mounted in different positions on the two flange plates.
  • the flange plates are then mounted directly or indirectly via an intermediate plate on the reversing clamp of the CNC machine or mounted on the support bearing.
  • the grid accuracy of the bores, which accommodate the fitting bushes, is advantageously + - 0.01 mm.
  • the grid bores in the flange plates describe a rectangle, preferably a square.
  • Another exemplary embodiment of the invention provides that a plurality, preferably four clamping plates are provided which have grid bores on at least one side edge, the grid of which corresponds to grid holes on at least one flat side of the clamping plate.
  • a clamping tower can be formed in a simple manner, for example, by means of four clamping plates of this type.
  • At least one support plate is provided which is oriented perpendicular to the clamping plate or plates and perpendicular to the flange plates and has grid holes on the end faces, the grid of which corresponds to that of the grid holes in the flange plates.
  • FIG. 7 shows the same view as FIG. 6, the device being rotated by 90 °
  • FIG. 8 shows a rear view of the flange plate according to FIG. 5
  • FIG. 9 shows schematically the clamping plate and a flange plate measured a further arrangement of the invention
  • FIG. 10 shows a side view of the device in the arrangement according to FIG. 9
  • FIG. 11 shows a plan view of a flange plate and clamping plates mounted thereon according to a further arrangement of the invention
  • FIG. 12 shows a side view 11 shows the device in the arrangement according to FIG. 11
  • FIG. 13 shows a side view of the device which is rotated by 90 "in relation to FIG. 12
  • FIG. 14 shows section A of FIG. 12, and FIG.
  • FIG. 15 shows a further top view of a flange plate and clamping plates arranged thereon in a further arrangement of the clamping device according to the invention
  • FIG. 16 shows a side view of the clamping device according to FIG. 15
  • FIG. 17 shows a schematic diagram of an adapter according to the invention .
  • the tensioning device 1 can be used in the reversible tensioner 2 of a vertical machine.
  • the CNC machine is not the subject of the present invention and is designed according to the prior art.
  • the mounting and rotation of the tensioning device 1 according to the invention takes place in the reversible tensioner 2 in a conventional manner.
  • the tensioning device 1 differs from conventional tensioning devices 2 in that it is designed as a variable kit. It has two flange plates 4 and at least one clamping plate 5.
  • each flange plate 4 is provided with grid holes 7.
  • the clamping plate 5 has holes 6 with a corresponding grid spacing a on its end faces (see FIG. 4).
  • the clamping plate 5 can thus be mounted in different positions and at different locations with respect to the flange plates 4. Likewise, several clamping plates 5 can be mounted between two flange plates 4.
  • one of the flange plates 4 is advantageously mounted directly on the reversing clamp, for example a sliding block 8 is provided which serves to rotate the clamping device 1.
  • 9 and 10 show an embodiment in which only one clamping plate 5 is provided and which is suitable for very high workpieces.
  • Support plate 10 is provided.
  • the support plate 10 is narrower and thinner than the clamping plates 5, since it has at least two holes 11 on its end faces, which are at the same grid spacing as the grid holes 7 on the flange disks 4 and the holes 6 on the end faces of the clamping plates 5 are located.
  • the strength of the tensioning device 1 is increased considerably by the arrangement of a support plate 10.
  • fitting bushes 12 which are advantageously slotted, are provided.
  • the fitting bushes each protrude into both the flange plate 4 and the clamping plate 5.
  • the fitting bushes 12 ensure the exact alignment of the flange plates 4 and the clamping plates 5.
  • the actual connection of the flange plate 4 with the clamping plate 5 takes place by means of threaded bolts 13.
  • the number of threaded bolts 13 used depends on the load to which the tensioning device 1 is exposed during operation.
  • 15 and 16 show an embodiment of the clamping device 1 according to the invention, in which four clamping plates 5 are assembled to form a clamping tower.
  • the clamping plates 5 which are made narrower by the plate thickness S than the clamping plates 5 of the previously described exemplary embodiments, are also provided on their longitudinal edges 5 ′′ with bores 15 at a grid spacing.
  • the clamping plates 5 have corresponding bores 15 on one flat side In this way, the clamping plates 5 can be screwed to one another, with locating bushes, but also locating pins or the like, in turn, can be used for more precise positioning.
  • the clamping plates 5 are screwed together with the flange plates 4 via the grid holes 7. It is particularly important that the grid bores 6, 7, 15 described so far do not serve to fasten the workpieces 16, but rather to connect the individual parts of the clamping device to one another.
  • the clamping plates 5 only have special bores 17 on their clamping surfaces, which are used to fasten adapters 18.
  • the adapters 18 have corresponding bores 17 '. It can happen that not all special bores 17 on the clamping plate 5 are always used. In some cases, e.g. B. for mounting the adapter 18 suffice with two holes 17, 17 'can be found. In principle, however, the same bores 17 are always used for mounting the adapters 18 and the distance D between different groups of bores (FIG. 3) does not lie in any particular grid.
  • the adaptation to various workpieces 16 takes place without exception by means of different workpiece receptacles 19 in the adapters 18.
  • any desired workpiece 16 of different shape can be fastened on the clamping plate 5 without the need for an expensive drilling grid on the clamping plate 5.
  • the workpieces 16 are advantageously pressed down by conventional hydraulically actuated brackets or clamping irons, not shown.
