Definitions

  • the invention relates to a tool for installing a crimping element, equipped with a quick-release pull rod.
  • the invention also relates to the mounting method of the setting tool.
  • crimping elements are common in industry, and in particular in the fields of automotive, aeronautical or naval construction. A wide variety of crimping elements such as rivet nuts are used.
  • the crimping of elements is generally carried out by means of portable setting tools using oleo-pneumatic, electric or other power.
  • This type of setting tool has a pull rod intended to be screwed inside or around the element to be crimped.
  • the tool is also provided with a drive system in rotation, and with a traction system making it possible to carry out the screwing and the crimping of the element to be crimped.
  • the barrel of the nut is first inserted through a hole in the plate.
  • the pull rod of the tool advantageously comprising an external thread, is then screwed into the barrel of the nut.
  • a traction system integrated into the tool enables crimping of the element to be crimped.
  • This step consists of pulling the barrel of the nut in the direction of the plate so as to form a bead against the plate in order to crimp the nut.
  • the pull rod is then unscrewed, and the assembly comprising the nut and the plate is ready to be assembled to an external element.
  • the pull rod is easily interchangeable in order to adapt to the tapping or the thread of the element to be crimped, as well as its diameter and its length.
  • the interchangeability of the pull rod is also important for carrying out maintenance of the device in the event of wear or breakage of the rod.
  • the patent EN 3011759 on behalf of the applicant discloses a setting tool comprising a drive shaft provided with an axial groove having a specific shape. At the front, that is to say on the side of the working area, the groove has a smaller lateral dimension than at the rear, that is to say on the side opposite to the working area .
  • the drive shaft cooperates with a traction rod comprising a rear zone wider than the front zone, and whose dimensions are adapted to the width of the groove to avoid any lateral play. To position the pull rod on the setting tool, no tools are required, just insert the pull rod into the groove. The pull rod is therefore easily interchangeable according to the needs of the user.
  • the groove confers a degree of lateral freedom on the pull rod, and the latter could move slightly despite the fixing of the laying nose around the drive shaft and the pull rod. This can generate asymmetrical forces when crimping the nut, and the latter may not be perfectly orthogonal to the plate to which it is fixed.
  • the document US 7032281 discloses a rivet gun that has a hydraulic piston.

  • An object of the invention is to produce a setting tool comprising a setting nose provided with a traction rod which can be easily and quickly interchanged, and which exerts perfectly symmetrical forces during the crimping of the element to be crimped.
  • the invention is also remarkable in that the dimensions of the pull rod, of the cavity, of the first hole and of the second hole are adapted so that the front end of the pull rod can successively pass through the first hole and the second hole when the pull rod passes through the cavity and so that the rear end can only pass through the first hole, and in that the pull rod comprises at its front end at least one thread for screwing in the element to be crimped .
  • the rear wall of the pull rod may include a pattern configured to cooperate with a complementary pattern of the drive shaft.
  • the second hole may not be of revolution along the axis of rotation AA of the drive shaft.
  • the pull rod may comprise a shoulder having a shape complementary to the shape of the pull sleeve in a zone situated forwards, the shapes being flared towards the rear.
  • the shoulder may have rotational symmetry along the first axis, and the traction sleeve may be mechanically dissociated from the drive shaft, so that the pull sleeve remains stationary during rotation of the pull rod.
  • the laying nose may comprise a carcass inside which the chamber is located, an anvil positioned at a front end of the laying nose, and means for adjusting the stroke of the traction rod placed between the carcass and the anvil, and configured to lock the relative position of the anvil with respect to the carcass.
  • the means for adjusting the stroke of the pull rod can consist of a clamping lock nut.
  • one of the imprints is in the form of a cross or a star.
  • one of the imprints is in the form of a polygon.
  • the drive shaft is mounted to move in translation along its axis of rotation to couple or uncouple the first cavity with the second cavity.
  • the method may also include a step of adjusting the adjustment means on the carcass, so as to limit the stroke of the traction rod.
  • the installation tool assembly method may comprise a step of assembling the pattern and the complementary pattern.
  • the method includes a first step of translation of the drive shaft along the axis of rotation of the drive shaft to reduce the size of the drive shaft along the axis of rotation and place the pull rod along the axis of rotation.
  • the method comprises a second step of translation of the drive shaft along the axis of rotation of the drive shaft to couple the first cavity with the second cavity.

  • Each of the two ends of the laying nose 2 has an orifice connected to the chamber 3 to allow passage of the pull rod 4 during its assembly or disassembly.
  • the pull rod 4 is configured to be mechanically coupled with the element to be crimped. In this way, the movements and the forces produced by the traction rod 4 are transferred to the element to be crimped.
  • the pull rod 4 is configured to be screwed into or around the element to be crimped then unscrewed when the crimping is performed.
  • the pull rod 4 may comprise at its front end 4a either a thread or an internal thread, or both in order to allow the crimping of two types of crimping elements having different properties.

  • the pattern can be a 4d groove, and the complementary pattern can be a tongue, or vice versa.
  • Other patterns can be made instead of the groove and the tongue, for example patterns in the shape of a cross or stars. In this way, the rotational movement of the drive shaft 5 is transferred to the pull rod 4.
  • the traction movement of the rod is carried out using a traction sleeve 6 which is movable only in translation along the axis AA.

  • the traction rod 4 is therefore inserted into the traction sleeve 6 by being placed along an axis BB passing through the first and second holes 6b and 6c (cf. fig.2 ).
  • the traction sleeve 6 can also be configured so that the traction rod 4 is both mobile in rotation along the axis AA relative to the traction sleeve 6, and no longer has any degree of freedom in translation along the axis AA after it has been correctly positioned. This feature makes it possible to exert perfectly symmetrical forces on the element to be crimped when the tool is in operation, and therefore to exert forces of greater intensity without risk of damaging the installation tool or the crimp element.
  • the cavity 6a may have a shape complementary to that of the rear end 4b of the rod 4 in a section plane orthogonal to the axis of rotation AA.
  • the fact that the traction rod 4 and the traction sleeve 6 are assembled without play in the zone 6d makes it possible to prevent the movement of the rod 4 perpendicularly to the axis of rotation AA, after the latter is correctly positioned in cavity 6a and mechanically connected to drive shaft 5.

  • the shoulder 4c and the zone 6d can be tapered (cf. fig.2 and 6 ).
