    TOOLS FOR LAYING A BLIND FASTENING AND METHOD FOR LAYING A FASTENING
    The present invention relates to a tool for installing a blind fastening in a structure.
    A “blind” fastener is commonly called a fastener which can be installed in structures to be assembled by a single side, said to be front or accessible, by deforming a part of the fastener disposed on the rear side, accessible or not, of said structures. The deformation takes place radially outwards during a traction or screwing step, to form a bulb or a bloom, said deformation pressing against the rear side. The structures to be assembled are thus kept clamped between a head of the binding disposed in abutment against the front side, and the deformed part in abutment against the rear side.
    Among the types of blind fasteners, there is a first type called "pull rivet", comprising a socket and a breakable mandrel connected together at one end of the fastener, the rivet being installed by applying only to the mandrel a pulling force while keeping the sleeve fixed in translation, until the mandrel breaks under the application of a predetermined tensile force. A second type called "screw rivet" comprises a threaded socket and a threaded mandrel, the rivet being installed by applying only a torque to the mandrel while keeping the socket fixed in rotation, until the mandrel breaks under a predetermined torque. A third type includes blind nuts, comprising a threaded nut and a removable mandrel, the nut being installed by screwing the removable mandrel into the nut, by pulling or turning the mandrel until a given traction or torque setpoint , then unscrewing the mandrel of the installed nut. Finally, a fourth type known as "screwed", comprises a screw provided with a head and a gripping element, and a threaded sleeve provided with a flange, to which a relative tensile force is applied to move the position of the screw by relative to the threaded socket and deforming a portion of the socket in order to form a bulb against the rear face of said structure. In the latter type, the gripping element is broken under the application of a predetermined torque. Such fixing is for example described in application FR3016417 of the applicant.
    An objective of the invention is to provide a tool for manual installation of blind fasteners of the "pull-screw" type.
    For this, the invention provides a tool for installing a fixing in a structure by a front face of the structure.
    The fixing comprises a screw comprising a barrel with a head and a threaded end, a gripping element which can be broken under the application of a predetermined breaking torque and a threaded sleeve capable of deforming radially outwards in order to form a bulb against a rear face of said structure.
    The installation tools include:
    - a body, substantially of revolution, extending along a longitudinal X axis, comprising at a first front end an axial opening allowing the passage of the gripping element and the head of the binding,
    - A first sheath movable axially and in rotation in the body, capable of driving the gripping element of the screw in axial translation and in rotation about the X axis;
    - A second sheath movable axially in the body and immobile in rotation, said second sheath being arranged to drive the first sheath in axial translation;
    - a rotary drive means comprising a rotating shaft provided:
    o of a first free wheel capable of driving the first sleeve in rotation in a first direction of rotation of the shaft, o of a second free wheel being able to drive in rotation a drive element arranged coaxially around said second free wheel in a second direction of rotation of the shaft, opposite to the first direction of rotation, the drive element cooperating by a helical connection with the second sleeve so as to move said second sleeve in axial translation.
    The installation tools obtained make it possible to install blind fixings of the “pull-screw” type with a simple and mechanically robust architecture, which requires only a few elements to carry out the traction movement and the rotation movement carried out successively. to install a fixture.
    The fitting tool for a binding according to the invention also preferably has all or some of the following characteristics, taken alone or in technically operable combination:
    the drive element is a threaded screw, a ball screw, a roller screw or a worm screw.
    the first sheath comprises movable elements capable of cooperating with the blocking portion of the gripping element of the binding in order to secure in the axial direction the binding with the first sheath.
    a first ring is arranged on the first sheath so as to be able to slide between a first position in which the movement of the mobile elements is blocked in the radial direction and a second position in which the movement of the mobile elements is free in the radial direction .
    a second ring is capable of sliding in the axial direction on the body and interfaced with the first ring to drive the first ring only towards the second position.
    the first freewheel is slidably mounted in the axial direction on the rotating shaft.
    the first freewheel is mounted on a third ring slidably mounted in the axial direction on the rotating shaft.
    a compression spring is disposed between the third ring and the drive element.
    an elastic means is fixed at one end to the drive element and at another end to the body, this elastic means being tensioned during the rotation of the shaft in the second direction and expanding to push the element drive when the rotating shaft rotation is stopped and / or reversed.
    - The elastic means is a torsion spring or a spiral spring.

    To facilitate reading of the drawings, only the elements necessary for understanding the invention have been shown. The same elements have the same references from one drawing to another.
    Attention is drawn to the fact that all the sectional views of the fitting nose presented in the different figures are not taken in the same axial plane. In particular views 2, 3 and 7 are made in a first axial plane and views 4, 5 and 6 are made in another axial plane.
    With reference to FIG. 1, a blind fastener 10 of the “pull-screwed” type to which the invention applies comprises a screw 12 and a socket 14. The screw 12 comprises a gripping element 16 capable of being broken during the installation of the fixing, a rupture groove 18, a countersunk head 20, a cylindrical barrel 22 and a threaded end 26. The gripping element 16 comprises a first gripping portion 28 in the form of a cylinder, a blocking portion 30 and a second gripping portion 32, comprising grooves distributed over the outer surface.
    The sleeve 14 comprises an enlarged flange 40 capable of receiving the countersunk head 20 of the screw, and a tubular barrel 42 comprising a thread 48, disposed at the end of the sleeve 14, opposite the flange 40. The thread of the screw 12 and the thread of the sleeve 14 are complementary. The tubular barrel 42 includes a deformable zone, not shown in the drawing, of stiffness less than the stiffness of the other portions, capable of forming a bulb under the effect of a traction.
    FIG. 2 is a sectional view of a fitting nose 200 of a tool suitable for fitting a blind fastener 10 previously described. The laying nose comprises a body 210 substantially of revolution, substantially cylindrical, hollow extending along an axis X, comprising a first end 212 and a second end 218 opposite the first. For convenience, in the following description, the first end 212 is called the front end and indicates the direction "forwards", while the second end is called the rear end and indicates the direction "backwards". The terms "in translation" and "axially" are used in an equivalent manner to designate a linear movement along the X axis.
    The front end of the body (210) has a contact surface 214 arranged to come into contact with the flange 40 of the threaded sleeve, and an opening 216 of sufficient diameter to allow the passage of the gripping element 16 and the head 20 of the screw 12 inside said body.
    The body 210 receives within it a first sheath 220, mobile in rotation and in translation inside said body. The first sheath is of substantially tubular shape of revolution around the axis X of the body. It extends between a first end close to the front end 212 of the body, and a second opposite end. A first ring 222 is arranged on a first portion of the first sheath 220 adjacent to the first end of the first sheath. Elements 224, distributed around the axis, movable in at least one component of the radial direction are held inside the body 210 between the front end 212 of the body and the first sheath 220. The first ring 222 is movable axially on said first portion of the first sleeve, between a first position in which the mobile elements are partially surrounded by the first ring 222 (FIG. 2) and free to move radially, and a second position in which the mobile elements are completely surrounded by the first ring 222 (Figure 3) which blocks their movement in the radial direction.
    A first compression spring 226 is disposed between the first ring 222 and a second sleeve 230. Under the effect of the first compression spring 226, the first ring 222 is pushed axially forward. In the rest position of FIG. 2, the stroke of the first ring 222 towards the front is limited by the mobile elements 224, the ends of which are closest to the front and form a cone having an outside diameter greater than the inside diameter of the first ring 222.
    A second ring 228 is arranged around the body 210, close to the front end 212 of said body. The second ring 228 can slide on the body backwards, against a second compression spring 229.
    The second sleeve 230 is housed inside the body 210. It is axially movable inside the body, but kept immobile in rotation. The second sheath is of substantially tubular shape of revolution around the axis X of the body and extends between, at the front, one end of a first portion 232 close to the second end of the first sheath 220, and, at the rear, a second opposite end. The second sheath 230 comprises an external surface of the six or eight-sided type engaged in complementary surfaces of the body 210 to immobilize the second sheath in rotation in the body. Other anti-rotation devices allowing translation are possible, such as key devices, key or other grooves.
    The first portion 232 of the second sheath covers a second portion 228 of the first sheath 220, adjacent to the second end of the first sheath. An outer surface of the second portion 228 of the first sheath forms an external shoulder and an inner surface of the first portion 232 of the second sheath forms a stop, close to the front end of said first portion of the second sheath, receiving the shoulder of the first scabbard. The shoulder and the stop include complementary bearing surfaces allowing the transmission of a translational movement from the second sheath 230 to the first sheath 220 towards the rear end 218 of the body. Other means of translational training of the first sleeve can be used.
    The body 210 also includes a drive means capable of driving the first sheath 220 in translation and rotation, and capable of driving the second sheath 230 in translation. The drive means comprises a shaft 240 extending along the axis X between the second end of the first sleeve 220 and the rear end 218 of the body. The shaft is mounted to rotate about a longitudinal axis of said shaft and can be rotated in two possible directions of rotation about its axis. At the front, the shaft is provided at a first end with a first free wheel 242, disposed at an interface with the second portion 228 of the first sleeve 220. The shaft comprises at a second end close to the rear end 218 of the body a rotational drive means (not shown) which can drive the shaft in a direction of rotation and in the opposite direction. A second freewheel 244 is arranged around the shaft 240, arranged axially between the first freewheel 242 and the means for driving the shaft in rotation. A drive element 246 is arranged coaxially around the second freewheel 244.
    Each free wheel 242, 244 conventionally comprises an inner ring and an outer ring such that, in one direction of rotation, the free wheel turns freely without securing the inner ring with the outer ring - the so-called free wheel phase, and in the other direction of rotation the inner ring is integral with the outer ring and transmits a torque to the part linked to the outer ring.
    The first free wheel 242 is arranged so as to cause the first sleeve 220 to rotate during rotation of the shaft in a first direction of rotation. The second freewheel 244 is arranged so as to rotate the drive element 246 in rotation during a rotation of the shaft in a second direction of rotation, opposite to the first direction of rotation. The freewheels 242 and 244 are in the freewheeling phase in opposite directions of rotation. The first freewheel 242 transmits a torque in the direction of rotation identical to the direction of screwing of the screw 12 in the socket 14.
    The first freewheel 242 is slidably mounted on the shaft 240 by means of a third ring 248 coaxial with the shaft and capable of sliding on the shaft. The third ring 248 and the shaft 240 are secured in rotation, for example by a hexagon or any other anti-rotation form, or by any other mechanical means such as key or key systems. The third ring 248 comprises a stop 250 bearing on the one hand against an internal shoulder of the second portion 228 of the first sleeve, and on the other hand against the first free wheel 242. A third compression spring 252 is housed around the shaft 240, between an internal shoulder of the drive element 246 and the third ring 248.
    The drive element 246 comprises a first portion 254 arranged coaxially around the second freewheel 244, and a second portion 256 extending coaxially around the shaft, at a distance from the shaft. In this example, the first portion 254 of the drive element comprises an external rotation drive surface, for example a hexagon, and the second portion 256 of said drive element comprises an external surface of the ball screw type. . The ball screw cooperates with an inner surface of the second sleeve 230 of the ball nut type. Thanks to the helical connection between the drive element 246 and the second sleeve 230, and the fact that the second sleeve 230 is stationary in rotation in the body 210, the rotation of the drive element 246 causes the translation of the second sleeve 230 towards the rear of the body when the shaft is rotated in the direction of transmission of the torque from the second freewheel. In this direction of rotation, the first free wheel 242 is in free wheel condition, and does not rotate the first sleeve.
    Other types of helical connections between the drive element and the second sleeve are possible, such as connections using conventional screws / nuts, roller screws or worms.
    The first portion 254 of the drive element 246 forms a flange 258 extending radially outward. A spiral spring 260 is housed in the radial direction in the body 210 around the first portion 254 of the drive member, one end of said spring being fixed to said first portion 254, while the other end is fixed to the body 210. The spiral spring is contained in the axial direction between the flange 258 of the first portion of the drive element and a stop 262 of the body. The spiral spring 260 is tightened on itself when the shaft is rotated in the direction of blocking rotation of the second freewheel 244. The spiral spring expands when the shaft is rotated in the opposite direction of rotation.
    Alternatively, the spiral spring can be replaced by a torsion spring. The spiral spring is less bulky and offers greater adjustment latitude than the torsion spring.
    The setting tool also comprises an ejector comprising a rod 272, one end of which can slide in the shaft 240, a fourth compression spring 274 housed in an interior space of the shaft 240 and pushing the rod 272. The ejector comprises also a support element 276 disposed at an opposite end of the rod 272, which can slide in the first sheath 220 and which can bear against an external surface of the first portion 28 of the gripping element 16 of the screw. In the rest state, in which no fixing is inserted in the fitting nose, the support element 276 of the ejector is pushed by the fourth compression spring 274 forward so as to be facing the opening 216 of the body 210.
    The method of fitting a blind fastener 10 by means of the fitting nose 200 will now be described, in conjunction with FIGS. 3 to 7.
    In a preliminary step, an operator grasps a binding 10 in the state shown in FIG. 1, and inserts it through the opening 216 before the body. The gripping portion 28 of the screw pushes radially outwards the movable elements 224 which snap into the locking portion 30 of the binding once the first gripping portion 28 of the screw is completely inserted in the nose of the screw. pose (figure 3). The mobile elements 224 then have an outside diameter smaller than the inside diameter of the first ring 222, which is free to slide forward under the action of the first compression spring 226, so as to trap the mobile elements around the portion gripping the fastener (Figure 3) and blocking the fastener 10 in the installation nose in the axial direction.
    When the first portion 28 of the gripping element is entirely contained in the positioning nose 200, the support element 276 of the ejector, pushed backwards, compresses the fourth compression spring 274 in the shaft 240.
    The binding 10 is then inserted into at least two structural elements 400 to be assembled, having a front face 402, on the side of which the binding is inserted, and a blind face 404 opposite the front face. For simplicity, the structure is represented globally in FIGS. 3 to 6 without representing the elements which are assembled to constitute it. The contact surface 214 of the body rests on the flange 40 of the binding.
    The first step is to form a bulb against the blind face 404 of the structure. To do this, the shaft 240 is rotated in the direction of rotation of the second free wheel 244. The spiral spring 260 is tensioned, a translational movement is imparted to the second sleeve 230 via the screw / nut connection ball. The second sleeve 230 moves backwards (Figure 4 - arrow F1) and drives the first sleeve 220 by the engagement of the bearing surfaces of the shoulder of the first sleeve 220 and the first stop of the second sleeve 230, thus that the third ring 248 arranged around the shaft, in fact driving the first free wheel 242 towards the rear, and compressing the third compression spring 252.
    The first sleeve 220 and the first ring 222 drive the gripping element 16 of the screw towards the rear, and therefore the threaded portion 26 of the screw and the internal thread 48 of the sleeve towards the blind face 404 of the structure, up to 'to the formation of a bulb 58, one face of which bears against the blind face 404. The head 20 of the screw 12 is then contained in the body 210 of the setting tool. The contact surface 214 of the body always maintains the socket 14 in the structure 400 (FIG. 4).
    The second step consists of screwing the screw 12 into the socket 14 to bring the head 20 of the screw back into the collar 40 of the socket. The rotation exerted on the shaft 240 is stopped and a reverse rotation movement is printed. The combined actions of the spiral spring 260 and the third compression spring 252 cause the second sleeve 230 and the third ring 248 to move in translation forwards (FIG. 5, arrow F2), while the rotation of the shaft in the direction of rotation of the first free wheel 242 rotates the first sleeve 220 in the direction of screwing of the screw, towards the front. In this direction of rotation, the second freewheel 244 is in the freewheeling phase and does not rotate the drive element 246.
    FIG. 5 illustrates the end of this movement: the first sleeve 220, the second sleeve 230, the first free wheel 242 and the third ring 248 have returned to their initial positions as shown in FIG. 2, the head 20 of the screw being of again in support in the collar 40 of the sleeve.
    The third step consists in finalizing the installation of the rivet by breaking the gripping element 16 of the screw while continuing to rotate the shaft 240 in the direction of rotation of the first free wheel 242. The rupture groove 18 is designed to break beyond a certain torque to ensure the desired tightening for fixing. It therefore breaks once the threshold is reached, leaving the head 20 flush with the front surface 402 of the structure (FIG. 6).
    To eject the broken gripping member 16, the operator grasps the second ring 228 and pulls it towards the rear of the body. By a system of keys, the first ring 222 is pulled backwards (FIG. 7). In doing so, the first ring 222 releases the front end of the movable elements 224 which are again radially movable. The ring 222 no longer maintains the movable elements 224 in the locking portion 30 of the gripping element 16, the support element 276 of the ejector is pushed forward under the action of the fourth compression spring 274, which ejects the gripping element 16 out of the fitting nose 200. The ejector also pushes radially the movable elements, which return to their initial positions in FIG. 2, maintaining the first ring 222 in a rear position when the operator releases the second ring 228, and the second compression spring 229 brings the second ring 228 back to the initial position of FIG. 2. Another blind fastener can be installed according to the same procedure.
    This manual installation tool can be used with any type of fastening 5 of the "pull-screw" type, by adapting the mobile elements 224 and the sleeve gripping means 220 to the shape of the gripping element 16 of the screw.
    Of course, the setting tool 200 can also install protrusive head fasteners.
