Definitions

  • the invention relates to a clamping tool with at least two jaws seated on a rack, at least one of which is displaceable on the rack and can be fixed thereon.
  • Clamping tools are already known in which the movable jaw can be moved along a rack.
  • a disadvantage of these clamping tools was that the clamping surfaces provided on the jaws or on the pressure plates which were arranged at the ends of the jaws were smooth and flat. It was probably possible, for example, boards, boards or the like. Clamping parts together, fixing the clamping tool to cylindrical or similar curved parts or the like was difficult because such bodies no longer found a hold on the flat jaws or pressure plates, even with slight mutual misalignment, and when tightening the clamping spindle of the clamping tool the cheeks could slide out.
  • the clamping tool consists of the fixed jaw 1, which carries a rigid pressure plate 2 at its free end.
  • the fixed jaw is in one piece in the illustrated embodiment with a rack 3, which on her. the pressure plate 2, the narrow side lying first, is provided with saw-like teeth 4.
  • the steep flanks of these teeth face the fixed jaw 1.
  • it can have a central rib 6 which divides the teeth 4 into two rows of teeth 5, 5 '.
  • the central rib 6 can optionally protrude beyond the tooth tips of the teeth 4.
  • the two rows of teeth 5, 5 ' can be offset by half the tooth pitch, as shown in Fig. 2.
  • the movable jaw itself is designated 7. It carries a pressure plate 9 which can be pivoted about a bolt 8, the pressure surface of which is provided with a groove 10 running in the central plane of the tool. In addition to this, a groove 11 running perpendicular to the groove 10 can be provided, which when the instep is closed Tool is in a plane perpendicular to the pressure plates and containing the axis of the pin 8.
  • the grooves 10, 11 preferably have an approximately semicircular or U-shaped cross section.
  • the pressure plate 2 seated on the fixed jaw 1 can also be provided with such grooves.
  • the displaceable jaw 7 has an opening 12 which surrounds the rack 3 with a corresponding play.
  • the rib 13 projects into this opening, which can fall into the gaps between the teeth 4 and then prevents the movable jaw from further displacement.
  • the rib 13 has a transverse groove 14 into which the central rib 6 can penetrate.
  • a suspension which is completely protected in a housing 21 against external influences, e.g. a leaf spring 15 or the like by means of a rivet 16. attached at one end.
  • the free end of this spring 15 continuously presses on the flat long side or narrow side 17 of the rack 3.
  • This free end of the spring 15 is further away from the fixed jaw 1 than the rib 13, i.e. the rib 13 lies between the two ends of the spring 15.
  • This type of mutual arrangement of the rib 13 and the spring 15 ensures that the movable jaw 7 is always preloaded away from the fixed jaw 1.
  • a different spring construction can of course also be selected within the scope of the invention.
  • a bead 18 is provided at the lying nearest the free end of the spring 15 end edge of the movable jaw 7, in order, as will be described to facilitate the 'displacement of the jaw. 7
  • a threaded hole for receiving the clamping spindle 19 is provided in the movable jaw 7.
  • a bell 20 protects the spindle from damage and dirt.
  • the thumb 18 acts on the bead 18 against the force of the spring 15, so that the rib 13 is detached from the teeth 4.
  • the jaw 7 can now be moved freely and silently along the rack 3 in both directions. After striking the movable jaw on the parts to be clamped or on the part to be held in place, the rib 13 is snapped into a gap between the teeth 4 by releasing the pressure on the bead 18. Due to the action of the spring 15, the movable jaw is already pressed against the parts to be clamped with a certain preload.
  • the presence of the groove 10 or the grooves 10 and 11 in at least one of the pressure plates ensures that these parts can no longer be pressed out of the jaws when the spindle 19 is now tightened.
  • the invention is not tied to the embodiment shown; rather, all the features of the invention can also be applied to other forms of training, for example on collets with two movable jaws and the like.
  • a likewise movable jaw can be provided for using the clamping tool for large spans, which jaw can be latched into teeth 30 of the rod 3 (FIG. 3).
  • the teeth 30, as can be seen are at a greater distance than the teeth 4 and are only used for rough adjustment of the distance between the two jaws 1, 7 by the jaw 1, while the fine adjustment or clamping by the jaw 7 in the teeth 4 takes place after the jaw 1 has been supported on an object.
  • the teeth 30 can be simple grooves.
