Definitions

  • the present invention relates to collets of the so-called “vice pliers type comprising a main lever of which a first fixed jaw is integral, a second jaw being mounted oscillating on said main lever and being connected to a second point of said main lever by a toggle device forming both an auxiliary operating lever and a device for locking the two jaws in the clamping position.
  • Clamps of this type are known, in particular from document US-A-2 853 910, but they serve exclusively to take parts and keep them locked between their jaws, they do not make it possible to extract or position cylindrical parts where other forms whose access is only possible from the inside of said parts, for example, but not exclusively, a socket, a washer, a nut located in a recess.
  • the object of the invention is to provide a remedy to this drawback and as characterized in claim 1, the vice grips of the aforementioned kind being characterized in that the jaws form a tapered beak comprising at its end at minus two notches to allow the gripping of small hollow parts by penetration inside or by clamping outside.
  • the gripper jaws are introduced after having brought them together against a spring which forces them to move away as soon as the pressure exerted on the gripper levers ceases, the gripped part thus remaining retained around said jaws of the clamp.
  • the figures represent a clamp which comprises, in the known manner, a main lever 1 in the form of a yoke, one end of which is equipped with a fixed jaw 2.
  • the movable jaw 3 is connected to the fixed jaw by a hinge pin 4 located in the enlarged part of the lever 1 and by a toggle 5 whose free end slides in the hollow of the yoke of the lever 1, while a spring-loaded cam 6, articulated in the yoke-like branch of the jaw mobile 8, provides instantaneous unlocking or blocking of the jaws against a coil spring 9 connecting the mobile jaw 3 to a fixed point 10 of the main lever 1.
  • the jaws 2 and 3 are in the form of a tapered beak, the inner part being cut to form the jaws 2a-3a.
  • the extreme outer part of the jaws 2 and 3 comprises gripping means constituted by notches 11, the end 1a of which is rounded and the external surface 11b of which is slightly curved or flat.
  • the shoulder 12 which follows the notch 11 serves as a stop at the edges of the part to be extracted from its housing.
  • the curved or flat exterior of the notches can be striated or cut like jaws 2a and 3a.
  • the operation of the clamp is very simple, fast and functional.
  • the jaws are more or less spread using the wheel 13, then the tapered beak is introduced into the bore or the tapping of the part 14, the movable lever 8 is released by accompanying it so as to allow the return spring 9 to act alone, which tends to spread the jaws 2 and 3 as far as possible, the movable lever 8 has no action in the operation.
  • the curved or flat outer part 11b of the jaws comes into contact with the inner surface of the part 14, the edges of which abut against the shoulders 12. It is then easy to lift the part 14 either to extract it from a housing or to position it in a recess where it is impossible to manipulate it by its external faces.
  • the pliers can be used for gripping parts from the outside as well as from the inside, which gives it a double advantage, it allows precise manipulation of parts that are difficult to access or positions them in recesses. themselves inaccessible.
