Definitions

  • the present invention relates to pliers capable of being used to exert a tensile force on sheets or the like, for example sheets of an automobile body for their straightening.
  • Clamps of this kind generally have a locking mechanism for locking them in the clamping position.
  • the mechanisms thus provided are not able to withstand the extremely large forces exerted during the straightening of the sheets of a bodywork.
  • the present invention aims to achieve a traction clamp, designed to be extremely robust and which includes an automatic clamping system under the very effect of the traction exerted.
  • This clamp has two jaws articulated one on the other at an intermediate point of their length, and it is characterized in that between the ends of these, opposite their gripping ends, a wedge is provided. expansion carried by a member intended to be coupled with the traction element of this clamp, for example a traction chain or cable, the clamping jaws comprising, on their internal face, ramps capable of cooperating with this wedge expansion.
  • the present traction clamp consists of two jaws 1 articulated one on the other at an intermediate point in their length. To this end, these jaws have, on their internal face, two legs 2 pierced with an eye intended to receive a hinge pin 3. These jaws are constituted by two absolutely identical parts, arranged in opposite directions and whose legs of articulation 2 are offset so that they can be nested together as shown in FIG. 4.
  • these two jaws are bent to form the actual clamping jaws 4, these advantageously having striations 5 in wolf teeth, or other suitable reliefs capable of allowing excellent gripping on T sheets, for example the sheets of an automobile body.
  • the jaws 1 are cut so as to present an offset heel 6.
  • these heels are nested as shown in FIG. 5.
  • An expansion wedge 7 is arranged between the ends of the two jaws 1, which are opposite their gripping ends. This corner, which extends transversely inside the cage formed by the corresponding ends of the two jaws, is carried by a stirrup 8 whose branches are located on either side of the sides of these jaws.
  • This stirrup is intended to be coupled with the traction element of the present clamp, for example a chain or a traction cable.
  • the end of this stirrup which is opposite the expansion wedge 7, may have a notch 9 intended to receive the ur of links of a traction chain.
  • the internal face of the two jaws 1 has a groove 10 capable of cooperating with the corresponding inclined face of this wedge, as shown in FIG. 2.
  • the ramps thus provided can be designed to allow force locking.
  • the present clamp makes it possible to exert very large tensile forces. Therefore it can be used on body straightening devices comprising traction cylinders intended to be coupled, by means of chains or the like, at various points of a body to be straightened.
  • this clamp is devoid of any fragile mechanism. Besides, this clamp is made up of a very small number of extremely robust parts capable of being made of high quality forged steel.
  • traction clamp according to the invention is not limited to the embodiment described above. Indeed, this clamp is capable of being the subject of various other embodiments.
