Definitions

  • the invention relates to a clamping table with an upper frame supported by legs, on the opposite longitudinal bars of which two plate-shaped clamping jaws are supported, of which the front clamping jaw can be adjusted against the rear clamping jaw by means of two adjusting spindles arranged in the longitudinal bars.
  • Such clamping tables primarily intended for do-it-yourselfers, are known in various embodiments.
  • Workpieces of widely differing sizes can be clamped on them, and in many cases it is also provided that the front clamping jaw can be adjusted at an angle to accommodate workpieces of widely differing shapes, e.g. also triangular workpieces.
  • the front clamping jaw has to be adjusted over a correspondingly large distance by means of the adjusting spindles, which is time-consuming and cumbersome.
  • a similarly time-consuming adjustment is also to be carried out when clamping, for example, triangular workpieces, with such non-rectangular workpieces and in particular workpieces with parallel sides, the clamping possibilities being limited in accordance with the maximum possible inclination of the front clamping jaw.
  • the invention has for its object to provide a clamping table in which the clamping work can be carried out more quickly and the clamping options are expanded with regard to irregularly shaped workpieces.
  • the rear clamping jaw is displaceably guided on the longitudinal spars and is equipped with locking pawls which engage in locking holes in the longitudinal spars and which can be lifted out of the locking holes by means of actuators and held in an unlocked position.
  • the rear clamping jaw is pivotable and displaceable to a certain extent in the clamping plane relative to the spindle-actuated front clamping jaw and relative to the longitudinal spars. It can be clamped in various swivel and / or linearly displaced positions, in particular locked in the provided locking positions.
  • the invention provides the advantage that when clamping a workpiece, the rear clamping jaw can first be pushed so quickly into the respective workpiece that it is already closely enclosed between the two clamping jaws, after which the tight clamping is carried out by starting the front clamping jaw. This eliminates the time-consuming adjustment work previously required when changing between two workpieces of very different sizes.
  • the rear clamping jaw can be adjusted obliquely with respect to the longitudinal bars, so that e.g. triangular workpieces a quick rough adjustment of the clamping jaws can be made before the final clamping takes place.
  • the simultaneous inclinability of the rear clamping jaw also provides the additional advantage that the clamping jaws can be aligned at an angle which is substantially larger, in general twice as large as the maximum adjustable angle on the known clamping tables.
  • the set of clamping prisms is assigned to the clamping jaws, each of which is provided with a lower pin which can be inserted into holes in the clamping jaws.
  • the clamping prisms each have the different workpiece shapes, e.g. Round or curved workpieces, adapted clamping sides so that workpieces of almost all conceivable shapes can be securely clamped using the clamping prisms.
  • the clamping table has an upper frame 5 carried by four collapsible legs 1, 2, 3, 4, on the opposite longitudinal bars 6, 7 of which two plate-shaped clamping jaws 8, 9 are slidably supported.
  • the longitudinal bars 6, 7 have a U-profile which is open towards the bottom and are connected at one end via a cross strut 10.
  • the clamping jaw 8 is supported by two sliding blocks 11, each of which can be moved on one of the longitudinal bars 6, 7, cf. Fig. 4, worn, in which a sleeve-shaped driver pin 12 of a spindle nut 13 engages, which is adjustable by means of an adjusting spindle 14 with a crank handle 15 along the longitudinal bars 6, 7.
  • the clamping jaw 8, the sliding block 11 and the spindle nut 13 are clamped together by a screw 16 screwed into the driver pin 12 provided with an internal thread.
  • 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 that they have the longitudinal edges of the longitudinal slot 18 between them in a known manner mounting.
  • the head of the screw 16 is seated with a washer 19 on the shoulder 20 of a stepped bore 21 formed in the clamping jaw 8.
  • the stepped bore 21 encloses the washer 19 and a sleeve-shaped extension 22 of the sliding block 11 with such radial play that the clamping jaw 8 can also be adjusted obliquely with respect to the longitudinal bars 6, 7.
  • the rear clamping jaw 9 is similarly slidably supported on the back leg 17 of the longitudinal spars 6, 7, a counterpart 23 (see FIG. 6) being arranged within the longitudinal spars 6, 7, on which the clamping jaw 9 and a sliding block 24 is fastened by means of a cap screw 25 enclosing the back leg 17 of the longitudinal spars 6, 7 provided with a longitudinal slot 26.
  • the sleeve-shaped extension 27 of the sliding block 24 and the washer 28 of the cap screw 25 are also received here with a relatively large radial play by a stepped bore 29, the part 30 of the washer 28 in diameter and the narrower part 31 of the approach 27 with radial play record, so that the rear jaw 9 is adjustable.
  • a locking pawl 32 is pivotally mounted about a horizontal axis 33, which engages with its relatively wide pawl nose 34 in locking holes 35 of the longitudinal bars 6, 7 and is loaded in the direction of engagement by a return spring 36.
  • each pawl 32 With each pawl 32 an actuator 37 is fixedly connected, each consisting of a hand lever 38 which extends at a distance below the rear clamping jaw 9 to behind its rear side and has an upwardly bent handle 39 which can be gripped under with a finger.
  • the pawl 32 can thus be lifted out of the locking holes 35 by means of the handles 39 and held in this unlocked position, after which the clamping jaw 9 can be pushed towards the respective workpiece to be clamped in, whereby, if necessary, the rear clamping jaw 9 can also be inclined can.
  • a set of clamping prisms 40, 41, 42, 43 is assigned to the clamping jaws 8, 9, each of which has a lower pin 44 (cf. also FIG. 1) with which they can be inserted into holes 45 in the Clamping jaws 8.9 can be inserted.
  • These loose, convertible clamping prisms 40-43 enable the clamping table according to the invention to be used very universally.
