Definitions

  • the length of the reciprocal guides corresponds to the height of the crossbeam
  • guide extensions are provided on the crossbeam which considerably increase the length of the guiding surfaces.
  • a lengthening of the guides is possible primarily on the inner edges of the columns, but also on the outer edges thereof, and moreover in upward and downward direction. It is evident that this will require a corresponding alteration in design to provide space for the guides; that is, an increase in height if they are extended in upward direction, and a wider spacing of the columns if the guides are extended downwardly while retaining the same gantry width.
  • the guides are lengthened in downward direction, the arrangement of such stiifening ribs is not always possible, and in certain cases not without a sacrifice in the gantry width.
  • the guides with clamping devices along their entire length. These devices should preferably be continually under tension and only automatically relieved before the crossbeam is moved. They should also again be placed under tension, preferably automatically, and the cross-beam fixed at the end of this movement.
  • Fig. 1 shows a crossbeam with a section through the box-shaped extension, taken on line 1-1 of Fig. 2,
  • Fig. 2 is a section through the crossbeam and columns, taken on line IIII of Fig. 1,
  • Fig. 3 shows the crossbeam in side elevation
  • Fig. 4 is a diagram illustrating the clamping device.
  • the crossbeam 5 has a box-shaped extension 7 reaching to the rear side of the columns 6 and is guided on the front sides 8 of the columns in dove-tail guides 9 and rectangular guides 10 in known manner.
  • the cross-sectional shape of the columns is such that at 11 it recedes from the inner edge 12, thereby providing space for the lower extensions 13 and the upper extensions 14 of the rear slides or guides 15 of the crossbeam box.
  • stiffening ribs 16 are provided for the upper extensions 14 and stifienings 17 for the lower extensions 13 which are much longer in comparison, the stiffening ribs 17 extending a substantial distance along extensions 13 and across the box shaped extension 7.
  • the gantry width is the same as on the known machines and the columns are arranged with their inner edges 12 at the same distance apart as on the known machines.
  • the clamping is effected by two clamping bars 18 near the crossbeam 5 and two other clamping bars 19 at the rear end of the box-shaped extensions 7; both sets of bars, as can be seen from Figs. 1 to 3, extend along the entire length of the guides.
  • These clamping bars swivel on bearings 20 and 21 respectively and are actuated by a spindle 22, two cam levers 23 and two connecting rods 24 in the manner shown in Fig. 4.
  • Spindle 22 of Fig. 2 can be rotated by a servo-motor, not illustrated. Thereby a nut 26 is displaced on the left threaded end 25 of spindle 22 which is loosely pivotally connected with lever 23.
