Definitions

  • the present invention relates to a claw extractor, in particular a large claw extractor, comprising improvements intended to facilitate its handling.
  • claw extractors are known in which the claws are articulated directly on the body of the claw extractor and comprise, at the end opposite to that intended to come into contact with the part to be separated, guide means which are in direct relation with a control member such as a cam plate for example. This is intended to separate or bring the claws apart from each other, as well as to keep them in contact with the part to be removed, as long as they do not stick to it thanks to the force exerted by the 'extractor
  • the present invention therefore aims to provide a claw extractor of improved construction which can be easily handled by an operator who can guide the extractor as well as adjust the spacing of the claws until the pressure of the rod on the workpiece separate is sufficient for the claws to remain in contact therewith.
  • Another object of the present invention is to provide a claw extractor which allows, thanks to an improved construction, a self-tightening of the claws in order to ensure good adaptation of the extractor to any part to be separated.
  • a claw extractor characterized in that it comprises a guide which is free to rotate around the axis of the extractor but fixed in translation along this axis.
  • said guide comprising grooves which make it possible to guide the simultaneous movement of the claws by an angular rotation thereof around the axis of the extractor.
  • said guide advantageously consists of a disc, mounted at the rear end of the extractor, which is opposite the end intended to come into contact with the parts to be separated, said disc having grooves in which the rear ends of the claws slide and which are arranged so as to extend from the center outwards.
  • said guide advantageously consists of a disc mounted at the rear end of the extractor, which is opposite the end intended to come into contact with the parts to be separated, said disc having grooves extending from the center outwards, in which slide pins fixed to the connecting rods, which are articulated on the claws and, moreover, connected to these by stirrups preventing the free rotation of the claws by compared to the connecting rods but allow a sliding of the claws therein.
  • the operator can continuously adjust the spacing of the claws by actuating the guide so that it rotates by a certain angle around the axis of the extractor.
  • the pins are moved away from the extractor by pivoting the connecting rod around the point of articulation on the extractor to bring the claws apart or move them apart.
  • said guide may advantageously include a control arm.
  • the present description relates to a hydraulic claw extractor. This does not exclude that the present invention can be applied also to q uence a manual extractor, for example.
  • the extractor 1 consists of a hydraulic cylinder (or other) 2 actuated by a hand pump (not shown), for example or connected to a source (not shown) of hydraulic fluid.
  • a hand pump for example or connected to a source (not shown) of hydraulic fluid.
  • To the cylinder of the jack are fixed three connecting rods 3 which are also connected to the corresponding claws 5.
  • the claws 5 have several holes 7 which are intended to allow adjustment of the spacing between the part 9 to be removed from the shaft 10 and the rod 12 which will bear against the end of this shaft 10.
  • the claw extractor comprises a guide 15 which is provided with grooves 17, preferably curved, in which slide pins 19 which are fixed to the connecting rods 3.
  • the pins approach or move away from said axis, according to the direction of movement, given the arrangement and the particular shape of the grooves 17.
  • the connecting rod 3 pivots around its articulation point 23 to move the claws 5 apart or closer to one another.
  • a stirrup 25 prevents the claws from rotating freely around the point of articulation 27 but allows the claw 5 to slide therein when the angular position of the connecting rod 3 is modified by the action of the guide 15.
  • the stud 19 is fixed to the connecting rod 3 by means of a sheet of steel folded partially around said connecting rod 3, in order to avoid movement. relative ment of the stud 19 with respect to said connecting rod 3.
  • any other form of assembly such as two bolts or two rivets, for example.
  • An advantage obtained by the present invention consists in that the handling operations are greatly facilitated and that a single operator is sufficient to use this apparatus, even when the dimensions are large enough.
  • the extraction operation consisting simply in bringing the apparatus into position and adjusting with the device of the invention. the spacing of the claws to be able to arrange it properly on the part 9.
  • Another advantage consists in that the guide 15, in the form of application shown, takes up little space and can be accommodated in the usual boxes delivered with this kind of equipment.
