  • the invention relates to a clamping device for clamping workpieces, especially for machine tools, with a bed that is longitudinal has running guide channel, which is flanked by lateral contact surfaces is, and with at least two movable along the bed and through Holding devices on the bed lockable sled, each the Support surfaces assigned to support surfaces and one in the guide channel have engaging guide approach, and at least one of which is a movable jaw.
  • the standing toothing provided here is advantageously able to not only absorb displacement forces, but also tilting forces, which is high Position accuracy and consequently high machining accuracy guaranteed. Since the tipping forces that are usually unavoidable due to the Gearing are included, none of the tilting forces absorbing Screws needed. To ensure reliable tooth meshing provided adjusting device can advantageously by only one Screw are operated. An elongation of this screw is in this Connection of the achievable clamping accuracy is not detrimental. As a result of Reduction of the means to be actuated to one screw of the adjusting device is a very simple, time-saving operation of the invention Device and thus an excellent ease of use guaranteed. It can also be assumed that the standing toothing significantly less prone to contamination or backfilling than a horizontal one Gearing, since chips etc. fall off, which also increases the effort for Keeping the teeth clean has been reduced. With the measures according to the invention are therefore the disadvantages of the known arrangements described above completely eliminated in a very simple and inexpensive way.
  • Rack teeth of the slide and guide channel are designed that when pressed together, the tooth tip and the opposite Tooth gaps are spaced from each other. This ensures a reliable flank system and thus a backlash-free mutual Meshing.
  • the toothed rack teeth can be used as fine teeth preferably be formed with a tooth pitch of 1-2 mm.
  • the Fine toothing advantageously allows small adjustment steps, which is has an advantageous effect on the required operating effort. Besides, that is Fine toothing comparatively safe against soiling from chips, because they cannot penetrate the fine toothing. This also increases the Ease of use and maintenance.
  • those of toothed side wall opposite side wall of the guide channel as oblique surface running at an acute angle to the adjacent support surface be formed and the adjusting device has a slide-side provided have movable wedge along the inclined surface, which by means of a top accessible screw is actuated.
  • the one interacting with the wedge Sloping surface advantageously results in a contact and hold-down force.
  • the tensioning device on which the drawing is based contains a by beam-shaped profile piece formed bed 1 on a table one Machine tool or on one on the table of a machine tool recordable additional device, such as on a dividing head, is recordable, as by clamping claws 2 engaging in a groove on the bed side is indicated.
  • the bed is 1 with a longitudinal, continuous, groove-shaped here Provide guide channel 3, which is open at the top.
  • the top ends of the Guide channel 3 laterally delimiting legs 4 of the bed 1 forming Profile piece form the guide channel 3 flanking, flat contact surfaces 5 for with assigned, planar support surfaces 6, which can be accommodated on the bed 1 Carriage 7 or 8 or 11. These are adjustable in the longitudinal direction of the bed 1 and fixable at any desired location.
  • At least two slides 7, 8 are provided, one of which, here the Carriage 7 has a stationary stop jaw 9 and the other, here the Carriage 8 is provided with a clamping jaw 10 which is displaceable for clamping.
  • the workpiece to be clamped is between the stop jaw 9 and the Clamping jaw 10 inserted and by moving the clamping jaw 10 by means of of an actuator described in more detail below against the Stop jaw 9 cocked.
  • the outer Carriages 7 and 11 each have the appropriate counter jaws. That's how it is Carriage 7 with a stationary stop jaw 9 and carriage 11 with provided here, displaceable clamping jaw 10.
  • the slides 7, 8, 11 each have a downwardly projecting, in the Guide channel 3 engaging guide lug 12, the two lateral, flange-like cantilevered support strips 13 is flanked, the underside of which the top mentioned, lying on the bed-side support surfaces 5, plan Have support surfaces 6.
  • a side wall of the guide channel 3 with a rack toothing 14 provided, that is, the teeth of the teeth are in the longitudinal direction of the bed 3rd arranged in parallel next to each other.
  • the facing side of the Guide approach 12 of the carriage 7, 8, 11 is with a corresponding, too provided as rack toothing 14 counter teeth, which with the toothed rack teeth 14 on the bed side in positive locking engagement is feasible.
  • the standing arrangement of the bed and slide side Rack toothing 14 enables displacement and tilt-proof Positive locking.
  • the guide approach 12 has so much play within the guide channel 3 that the bed and slide-side rack teeth 14 in and out brought mutual engagement and the carriage 7, 8, 11 when disengaged brought gears can be moved.
  • the bed and Rack-side toothing 14 are dimensioned so that at mutual meshing results in a reliable flank system. For this is the Dimensioning so that in the engaged state between the tooth head and a gap remains opposite the tooth gap base.
  • the rack teeth 14 are designed as fine teeth.
  • a Tooth pitch of 1 - 2 mm and accordingly a tooth density of 5 - 10 Teeth per centimeter has proven useful.
  • the toothed Areas are appropriately hardened. This can be through nitriding or partial Hardening the toothed areas or by hardening the entire, one Components containing gearing take place.
  • the bed and slide-side rack teeth 14 are useful as Straight gears formed, which ensures easy manufacture, although helical teeth would also be conceivable. In case of a Helical teeth are appropriately inclined so that they are in Clamp direction drop, which results in a hold-down effect.
  • the toothed Side wall of the guide channel 3 runs in the example shown under a right angle to the adjacent bearing surface 5 down, which is the manufacture facilitated. To create an additional downward force but it would also be conceivable to close the bearing surface 5 on the toothing side undercut that the toothed side wall of the guide channel 3 with the adjacent bearing surface 5 includes an acute angle. This is ensures that the carriages 7, 8, 11 with their support surfaces 6 reliably the bed-side support surfaces 5 are pressed when the bed and slide-side rack gears 14 in mutual engagement to be brought.
  • a Adjustment device provided on the side of the slide-side guide projection 12 of each slide 7, 8, 11 .
  • this is the toothed side wall of the guide channel 3 opposite side wall of the guide channel 3 as opposed to the adjacent support surface 5 formed at an acute angle to the outside inclined surface 15, that is there bearing surface 5 is undercut accordingly.
  • the carriages 7, 8, 11 are each with a wedge facing the inclined surface 15 that can be moved up and down 16 provided, which is movable with its wedge surface 17 along the inclined surface 15 is.
  • the wedge 16 is expediently vertical, that is to say in relation to the contact surface 5 guided vertically, as in the example shown by a guide groove 18 is indicated.
  • the wedge 16 is provided with a threaded bore into which one of Head 19 accessible at the top and supported on the assigned slide 7, 8, 11 provided screw 20 engages through which the wedge 16 is raised or can be lowered.
  • This lifting movement is caused by the inclined surface 15 in implemented a transverse to the lifting movement, through which the bed and slide side rack gears 14 in and out of engagement can be brought.
  • a hold-down force results which the carriages 7, 8, 11 with their support surfaces 6 to the bedside Contact surfaces 5 are pressed.
  • only one screw 20 has to be actuated, which is high Ease of use and quick operability results.
  • the jaws attached to the slides 7, 8, 11 in the form of the stop jaw 9 or jaw 10 are designed as interchangeable jaws that adapt to configured the configuration of the workpiece to be clamped or can be profiled.
  • the jaws mentioned are appropriately by Countersunk screws attached to the associated slide, the associated cheek-side recesses as reaching to the lower cheek edge Slits 21 can be formed so that the jaws 9 and 10 simply follow can be removed from above or inserted from above.
  • the stop jaw 9 is fixed on the assigned slide.
