Definitions

  • the invention relates to a clamping table according to the preamble of claim 1.
  • Such a clamping table is from the US-A-4,127,260.
  • the well-known clamping table has one upper frame supported by four legs, this has opposite longitudinal spaces, on which two plate-shaped jaws lie.
  • the front jaw is opposite the rear by means of adjusting spindles Adjustable jaw.
  • the rear jaw is on the longitudinal spars slidably guided and is opposite this longitudinal spars can be locked in an inclined position.
  • Locking devices are used for this, they are in shape sawtooth-shaped openings provided on the spar, in which a locking pawl can engage. By Lift this locking pawl out of the locking openings the rear jaw is adjustable.
  • a workbench is known from EP-A-0 436 500, in which the front jaw on two parallel Holmen lies and each by means of a crank mechanism is adjustable.
  • the rear jaw is in holes a row of holes on each spar in different Positions can be inserted.
  • a workbench is known from EP-A-0 068 258, at which is also the front jaw by means of a spindle drive is individually adjustable and in which the rear Lock the jaw in different positions can.
  • the invention has for its object a clamping table according to the preamble of claim 1 to create where the clamping work can be carried out more quickly and the clamping options expanded with regard to irregularly shaped workpieces are.
  • the rear clamping jaw attached to the Longitudinal spars is slidably guided and in locking holes the locking pawls engaging the longitudinal bars is provided, which is by means of actuators can be lifted out of the locking holes simply parallel or at an angle to the front jaw can be set.
  • the rear jaw can first by means of a quick adjustment to the respective Workpiece are pushed so far that this already closely bordered between the two jaws is.
  • the tight clamping is only by hiring the front jaw.
  • the rear jaw can be adjusted at an angle to the longitudinal spars, so that the coarse adjustment even with non-parallel ones Workpieces is possible before the final clamping he follows.
  • the front jaw is also slanted adjustable.
  • the locking openings are through on the Holes arranged on the top of the longitudinal spars.
  • the jaws can be a set of clamping prisms be assigned, each with a lower, in Provide holes in the jaws for insertable pins are.
  • the clamping prisms each have the different Workpiece shapes, e.g. B. round or curved workpieces, adapted clamping sides so that using the clamping prisms workpieces of almost every conceivable Shapes can be clamped securely.
  • the clamping table has one of four foldable Legs 1, 2, 3, 4 carried on the upper frame 5, on its opposite longitudinal spars 6.7 two plate-shaped jaws 8.9 are slidably supported are.
  • the longitudinal bars 6, 7 point downward open U-profile and are at one end over a Cross strut 10 connected to each other.
  • the clamping jaw 8 is of two, each on one of the Longitudinal bars 6.7 sliding blocks 11, see. Fig. 4, worn, in which a sleeve-shaped Driver pin 12 engages a spindle nut 13, which by means of an adjusting spindle 14 with a hand crank 15 is adjustable along the longitudinal bars 6.7.
  • the Clamping jaw 8, the sliding block 11 and the spindle nut 13 are provided with an internal thread in the Driver pin 12 screwed screw 16 tied together.
  • the back leg 17 of the longitudinal spars 6,7 has a longitudinal slot 18 through which the Pin 12 and the screw 16 protrude, and the Nut 13 and the sliding block 11 are so wide trained that the longitudinal edges in a known manner of the longitudinal slot 18 between them.
  • the head the screw 16 sits on a washer 19 the shoulder 20 one formed in the jaw 8 Stepped bore 21 on.
  • the stepped bore 21 encloses the washer 19 and a sleeve-shaped extension 22 of the sliding block 11 with such a radial Game that the jaw 8 against the longitudinal spars 6.7 can also be adjusted at an angle.
  • the rear jaw 9 is similar slidably on the back leg 17 of the longitudinal spars 6.7 supported, 6.7 here within the longitudinal spars a counterpart 23 (see FIG. 6) is arranged, on which the clamping jaw 9 and a sliding block 24 by means of a cap screw 25 enclosing the a longitudinal slit 26 provided back leg 17 of the Longitudinal bars 6.7 is attached.
  • the sleeve-shaped approach 27 of the sliding block 24 and the washer 28 of the Head screw 25 are also relatively large here radial play received by a stepped bore 29, whose part 30 in diameter the Washer 28 and its narrower in diameter Part 31 take the approach 27 with radial play, see above that the rear jaw 9 can be adjusted obliquely is.
  • each sliding block 24 of the rear jaw 9 is a locking pawl 32 about a horizontal axis 33 pivotally mounted, which with their relative wide jack nose 34 in locking holes 35 of the Longitudinal bars 6.7 engages and by a return spring 36 is loaded in the direction of engagement.
  • each pawl 32 With each pawl 32 an actuator 37 is fixed connected, which each consists of a hand lever 38 exists that is at a distance below the rear Clamping jaw 9 runs up to behind the back and one cranked upwards, with one finger has graspable handle 39.
  • the pawl 32 can thus be made longitudinally by means of the handles 39 lifted out of the locking holes 35 and in be held in this unlocked position, after which the jaw 9 in quick adjustment to the the respective workpiece to be clamped can be, if necessary also a Inclined adjustment of the rear jaw 9 made can be.
  • FIG. 3 As shown in Figure 3 is the jaws 8.9 assigned a set of clamping prisms 40,41,42,43, which each have a lower pin 44 (see also Fig. 1) with which they are in holes 45 of the jaws 8.9 can be inserted.
  • These loose, actionable Clamping prisms 40 - 43 allow a very universal Usability of the clamping table according to the invention.
