Definitions

  • the present invention is a clamping device for clamping workpieces according to the preamble of claim 1.
  • An object of the present invention is to provide a clamping device with which workpieces can be repeatedly positioned without the machine table of the machine tool is damaged and is no longer usable later.
  • the machine table remains in its training.
  • Another object of the invention is to design the clamping device such that a simple positional clamping, both of workpiece holders and vices or gauges without the use of tools is possible.
  • the inventive clamping device can be fixed by means of clamping screws and sliding blocks on the machine table and occurs in its place. There is no damage to the machine table and its grooves.
  • the original machine table can be used as such at any time by loosening the clamping device.
  • grooves can also be made on the clamping device which correspond to those on the machine table and can be used in the same way.
  • mechanically, hydraulically or pneumatically actuated clamping elements are used in the clamping device, which allow the tool-free clamping and after machining relax.
  • the clamping elements for example designed as slides, engage the clamping bolt and exert a downward movement on it, ie. the workpiece or the Werk Swisseinspannvorraum on the surface of the clamping device pressing force.
  • a vice 5 can be seen as a clamped element.
  • a vise 5 can also be directly attached a workpiece in the same way.
  • the machine table 3 has on its top T-shaped first grooves 7, which are formed parallel to each other and each at equal intervals.
  • the configurations of the first grooves 7 and their mutual distances are the same for most newer machine tools. In older machine tools and grooves 7 may be present at different distances.
  • the tensioning device 1 comprises a plurality of base plates 9, four in the present example, which are arranged side by side on the machine table 3 rest.
  • the base plates 9 are fixed with clamping screws 11 which engage in sliding blocks 13, immovably on the machine table 3 ( FIGS. 2 and 3 ).
  • each a clamping table 15 is placed, which may be constructed from a plurality of similar table elements 17.
  • the table elements 17 are preferably inserted in recesses 19 on the surface of the base plate.
  • second T-slots 23 are formed, which correspond to the existing in the machine table 3 first grooves 7 or may be different and not all extend over this.
  • the clamping table 15 could be made in one piece and the second grooves 23 milled into the latter.
  • FIGS. 1 . 2 and 3 further holes 29 are visible, through which clamping bolt 31 can be passed.
  • the clamping bolts 31 are connected by means of fastening screws 33 with the workpiece 5.
  • FIG. 1 further grooves 35 are visible, which extend on the surface of the clamping table 15 parallel to the grooves 23.
  • positioning pins 37 may be used. The latter are not described in detail because their structure and functioning FIGS. 2 and 3 is clearly visible.
  • the operation of the clamping device 1 will be explained in more detail.
  • the clamping device 1 is placed on the machine table 3 of a machine tool of any origin and attached to the latter with conventional clamping screws 11 which have been inserted into the first grooves 7 of the machine table 3.
  • the clamping device 1 now forms a "new" machine table and, if the clamping device 1 also has T- or trapezoidal second grooves 23, the same conditions for clamping a workpiece or, as in FIG. 1 shown as an example, a vise 5.
  • the holes 29 are additionally inserted in the clamping device 1, in which the clamping bolt 31 can be inserted.
  • the latter are connected with their upper end 63 to the workpiece or - as in the embodiment - with the vise 5.
  • the Clamping pin 31 to be mounted exactly at a distance of the mounted in the jig holes 1 29 and also so that the workpiece / the vise 5 exactly in the desired position to the tool (eg drill head, etc.) on the machine tool (both not shown) comes to rest ,
  • a suitable pressure source oil or air via the pressure line 57 in the rear pressure chamber 49, so that the latter in the groove 41 on the clamping bolt 31st engage and press it down so that the workpiece 5 comes to rest fully on the surface 65 of the table elements 17.
  • a pressure source a hydraulic unit can be used or it can be supplied by hand, for example via a spindle, oil from an oil reservoir via the oil pressure line 57. Compressed air can be taken from the in-house compressed air system.
  • compressed air is introduced from a compressed air source into the front pressure chamber 51 and, after the return of the oil by opening a valve in the oil pressure line 57 (valve not shown), disengaged from the clamping bolt 31 , Thereafter, the workpiece 5 can be lifted from the jig and a new, as described above, are used.
  • the tensioning device 1 is constructed in a modular manner, i.
  • several clamping device modules can be placed side by side and one behind the other on the machine table 3.
  • the loading of the tensioning devices 1 with oil and compressed air can take place by means of suitable connecting elements between the modules via a single oil pressure line 57 and a compressed air line 55.
