Definitions

  • the present invention relates to work benches, and its object is to provide a work bench with a clamping device which is particularly adapted to the gripping of articles of complex shape.
  • US-A 4 527 786 discloses a work bench having a pair of vice assemblies mounted on a frame, each vice assembly having a movable jaw and a fixed jaw, one vice assembly heing movable towards and away from the other, and with the movable jaws being capable of swivelling.
  • the present invention may be regarded as a development of this arrangement, and provides improved means whereby objects of irregular shape may be securely gripped.
  • a work bench comprises a rectangular frame 10 forming the workbench top, and supported on legs 12 which may be arranged to fold for storage.
  • One pair of opposite sides of the rectangular frame are provided with slots 14,16.
  • a third side carries a slide 18 along which a pair of jaws 20,22 are independently movable, each being coupled to its respective lead screw 24,26.
  • a second movable slide 28 is parallel to the first slide 18 and similarly carries a pair of jaws 30,32 each independently operable for movement along the slide by its respective lead screw 34,36.
  • This second slide is movable towards or away from the first slide 18 by means of a further lead screw 38, heing kept parallel to the first by means of pairs of pins 40,42, and 44,46 riding in the slots 14,16.
  • Each of the vice jaws 20,22,30,32 is freely rotatable about a vertical axis 50,52,54,56. This enables each jaw to accommodate itself to the shape of an object being gripped by the clamping arrangement, so that objects of any shape can be securely held.
  • each of the jaws of each pair is movable independently of the other.
  • each of the four lead screws 24,26,34,36 ends in a shank of non-circular, preferably square, section, and a handle of special construction is provided to engage these shanks.
  • the handle is shown in part section in Fiqure 5 and comprises a barrel 64 having a deep recess 66 of corresponding section such as to engage the shanks of the lead screws.
  • a permanent magnet 68 is inserted deeply into this recess and secured in position, so that when the handle is applied to the shank of one of the lead screws the magnet secures it temporarily in position.
  • Figures 6A - 6F comprise a series of diagrams showing the manner in which an object of irregular shape is gripped by the clamping jaws of the present invention and, for comparison, how a similar object would be held by the prior art arrangements acknowledged above.
  • the upper diagram represents the operation of the present invention
  • the lower left and right diagrams represent respectively the operation of the arrangements of US-A 4 527 786 and US-A 2 322 380.
  • diagram E and F relate to the butt-joining of separate sections, an operation for which work benches of this kind are frequently employed.
