Definitions

  • the present invention relates to devices for automatically fitting assembly systems such as screws, nuts, bolts, pinning staples, etc., and more particularly relates to their use on corresponding control machines, whether they are hand, screwdriver / unscrewer type, or automated or robotic type, in order to obtain a locking or unlocking of the assembly systems within these devices.
  • the non-automatic screwing / unscrewing nose concerned essentially comprises two coaxial elements, one of which, internal, ensures the rotational movement associated with screwing / unscrewing and the other, external, connected to a fixed element with limited angular movement, allows the actual positive locking of a clip inside the nose.
  • This locking results from a limited rotary movement of the external element relative to the fixed element (30 ° in the case considered where the fingerprint configurations are hexagonal), said external element being adapted by its imprint to rotate the body of the assembly system with respect to an imprint formed on the fixed element and which penetrates into a groove of this body: the setting out of coincidence of the angles of the hexes of the external element and said body, and the imprint of the fixed element blocks this body inside the nose.
  • a limited rotation between holding and gripping elements allowing the desired locking and / or unlocking occurs automatically during the screwing or unscrewing operations.
  • FIG. 1 The prior art recalled in FIG. 1 relates to a screwing / unscrewing nose for a pinning clip of an assembly A1.
  • the actual clip B1 has a hexagonal body axially traversed by a screw stapling mechanism activated by the tightening of a nut.
  • the assembly is controlled by a machine C, generally pneumatic.
  • the aim is first of all to produce the locking of the clip B1 by an external gripping element D coaxial with a rotating element E driven by the engine of the machine and connected to an element F fixed relative to the housing of the machine; said locking is effected by rotation of 30 ° of the element D relative to the element F holding the body of the clip.
  • a reverse rotation movement of 30 ° produces the unlocking of the clip.
  • FIG. 1 The prior art described in FIG. 1 can be extrapolated to the case of a screw assembly A2 according to FIG. 2 or to that of a bolted assembly A3 according to FIG. 3.
  • the combination of the elements to be used in the laying device is then D-E for the screw 82 which has to be driven. ner in rotation, while in the second case it is D-F for the screw B2 and D-E for the nut B3 which must be driven in rotation relative to the screw B2.
  • the machine C is able to carry out the sequences of rotation and axial displacement which are necessary for fitting the assembly systems, which sequences are not within the scope of the invention.
  • the invention therefore proposes, in the following description, an automatic mode of fitting and locking / unlocking which can be applied in the three assembly cases mentioned above and for various machines such as for example machines held by hand or machines of the automated or robotic type.
  • This automatic mode is obtained by a fourth drive element linked in rotation to the gripping element and which cooperates with the rotating element to allow the rotation of said gripping element, thus ensuring locking.
  • Figure 4 which relates to a device for applying a pinning clip, not shown, of known type, the fixed element 1, is terminated by a holding portion 1A, intended to receive the body of the clip in a hexagonal imprint 5, is linked to the housing of a control machine 7, and the rotating element 2, intended to receive the nut of said clip in favor of a hexagonal imprint 6, adapted to be driven in rotation by the engine of the machine (not shown), carries a radial boss 2a which is one of the components of the drive element identified 10 as a whole.
  • the gripping element 4 external to the elements 1 and 2, carries at its end a hexagonal imprint 3 identical to the imprint 5 and axially adjacent thereto.
  • the drive element 10 is completed by a flexible annular part 8, such as neoprene, bearing on the one hand radial and axial tongues 8a, 8b, the number of two in the example shown, and on the other hand threaded bulges to receive taper screws 9a, 9b whose heads are housed, on the one hand, in cylindrical radial housings of the element 4 and, on the other hand , in circumferential radial openings 1a, 1b with a preferred amplitude of 30 ° formed in the fixed element 1.
  • a flexible annular part 8 such as neoprene
  • the clip can be introduced since then, the hexes of the imprints 5 and 3. are aligned (or coincidentally).
  • a reverse unscrewing movement (according to arrow F ′ in FIG. 5) will cause the tongues 8a and 8b which will act in rotation, by means of the screws 9a and 9b, the element 4 with respect to the 'fixed element 1 and thus lock the clip since the impression 3 then rotates by 30 ° relative to 5 then placing the sides in non-coincidence (opposition of the hexagonal shapes).
  • This amplitude of 30 °, preferred in the case of hexagonal imprints, corresponds to half the angles between the faces of said imprints. More generally, the preferred angle of rotation is that which allows the shape of the head to be brought into opposition with respect to itself.
  • the locked clip can then be placed through the hole of the assembly to be produced and then be tightened there by screwing the nut, driven in rotation although kept axially fixed by element 2, with respect to the mechanism staple which thus slides in the staple body held by the fixed element 1. There is an unlocking of the staple.
  • FIG. 6 which applies to conventional bolts (hexagon) but which can be adapted to any other form of bolt head, in particular polygonal, which can be brought into opposition with respect to imprints of same shape by rotation of a determined angle, the process must be modified and adapted since the screw and / or the nut is only engaged with two elements, and moreover, in certain cases, the action in rotation on the screw (or nut) is suppressed while the locking action is still necessary.
  • the fixed element 12 is linked to the machine housing 21 (in a known manner) and the rotating element 11, driven by a motor (not shown), provided in the machine, carries a radial boss 11 a which is one of the components of the drive element marked 20 as a whole.
  • the gripping element 13 carries a hexagonal imprint 17 at its end, identical to the imprint 16 of an element 14 for holding the screw (or nut).
  • This element 14 carries, on the one hand, axial dog teeth 14a1 and 14a2 and, on the other hand, at least one ball screw 22a 22a and spring 22b whose external part is housed inside a slot preferably circumferential radial 13a of 30 °, practiced in element 13.
  • the drive element 20 is completed by a flexible part 19, similar to the part 8, carrying radial and axial tabs 19a, 19b, and its fixing to the element 13 is ensured by screws 23 of any type. known, not detailed here.
  • the elasticity of the tongues 19a and 19b is such that they can be driven by the boss 11a, possibly in several turns, until the circumferential stop of the screw 22 against one of the edges of the light 13a, without however being able to transmit at element 13 the entire driving torque of element 11. Element 13 rotates less quickly than the latter.
  • the axial relaxation after stopping at the screwing therefore allows the evacuation of the laying nose in the unlocked position which allows the introduction of a new screw or nut then the restarting of a new laying cycle.
  • the devices shown are adapted to a hexagonal conformation; but any other conformation (non-circular) allowing to be put in opposition with itself by rotation of a determined angle could just as well be appropriate (square, triangle, oval, etc.).
  • friction drive systems transmitting a torque from the rotating element to the gripping element could be of a completely different design, just as could be different.
  • friction system with ball and spring between fixed element and holding element, insofar as the results obtained above would be the same.
  • the number of bosses is arbitrary.
