    Blind fastening rivet with stepped barrel and associated installation method
    The present invention relates to a fixing rivet, of the type comprising: a screw comprising a threaded portion, a barrel and a head; and a bushing comprising a substantially cylindrical body, said body comprising a clamping zone, capable of receiving the barrel of the screw, and a deformation zone, adjacent to the clamping zone and capable of forming an external bulb; a flange adjacent to the clamping zone and able to receive the head of the screw; and a threaded portion adjacent to the deformation zone and able to cooperate with the threaded portion of the screw.
    The invention is particularly applicable to blind fasteners, that is to say fasteners installed through structures by one side of said structures, commonly called "accessible" side. These fasteners are used in particular in the assembly of aircraft structures.
    A rivet of the aforementioned type and an associated installation method are described in particular in document FR3016417.
    Deformation of the socket, which causes the outer bulb, can also affect the tightening area. In particular, a bulge may form inside the socket, near the outer bulb. When installing the rivet, this internal bulge can lead to seizure between the tightening area of the socket and the barrel of the screw, requiring greater screwing effort.
    The present invention aims to solve this problem, in particular by facilitating the screwing of the screw into the socket after the formation of the external bulb.
    To this end, the subject of the invention is a fixing rivet of the aforementioned type, in which the barrel of the screw has first and second cylindrical portions connected by a shoulder, the first portion being adjacent to the head and having a first diameter, the second portion being adjacent to the threaded portion and having a second diameter, less than the first diameter.
    According to other advantageous aspects of the invention, the fastening rivet includes one or more of the following characteristics, taken in isolation or in any technically possible combination:
    - the second diameter is between 80% and 95% of the first diameter;
    - the shoulder is configured so as to form a gradual transition between the first and second diameters;
    - a maximum diameter of the threaded portion is less than or equal to the first diameter of the first portion of the barrel;
    - a maximum diameter of the threaded portion is less than or equal to the second diameter of the second portion of the barrel;
    - The rivet has a maximum clamping capacity and a minimum clamping capacity, a length of the second portion of the barrel of the screw corresponding to a difference between said maximum and minimum clamping capacities;
    - The screw further comprises a gripping element connected to the head by a breaking groove.
    The invention further relates to an assembly comprising: at least one structure comprising first and second opposite surfaces and a bore opening on each of said surfaces; and a rivet as described above, in which: the collar of the sleeve is in contact with the first surface; the head of the screw is in contact with said collar; the deformation zone of the body of the sleeve is in an installed configuration, in the form of an external bulb in contact with the second surface; and the clamping region of the body of the sleeve has an internal bulge adjacent to the external bulb, said internal bulge being arranged opposite the second portion of the barrel of the screw.
    According to a preferred embodiment, a radial space is provided between the internal bulge of the sleeve and the second portion of the barrel of the screw.
    The invention also relates to a method of installing an assembly as described above from a rivet as described above, said method successively comprising the following steps: assembling the threaded portion of the screw with the tapped portion of the sleeve, the deformation zone of the body of said sleeve being in an initial cylindrical configuration; insertion of the sleeve into the bore of the structure, on the side of the first surface; holding the flange in contact with the first surface and axial traction on the screw, so as to deform the deformation zone of the body of the sleeve to form the external bulb of the installed configuration, the internal bulge of the tightening zone being simultaneously trained; and screwing the screw into the socket until the head of the screw and the collar of the socket come into contact, the second portion of the barrel of the screw then being positioned opposite the internal bulge.
    According to a preferred embodiment, the rivet comprises a gripping element and a rupture groove, said method then comprising a step of separating the gripping element from the head of the screw, by rupture of the rupture groove .
    The invention will be better understood on reading the description which follows, given solely by way of nonlimiting example and made with reference to the drawings in which:
    - Figure 1 is a sectional view of an assembly according to an embodiment of the invention, in an initial configuration;
    - Figure 2 is a sectional view of the assembly of Figure 1, in an intermediate installation configuration;
    FIG. 3 is a partial view, in section, of the assembly of FIGS. 1 and 2, in an installed configuration, and
    - Figure 4 is a detail view of Figure 3.
    Figures 1 to 4 show an assembly 10 according to the same embodiment of the invention. The assembly 10 comprises a structure 12 and a fixing rivet 14.
    The structure 12 comprises a first face 16 and a second face 18, opposite the first face 16. The first 16 and second 18 faces are substantially plane and parallel to each other.
    It is considered that the first face 16 of the structure 12 is accessible to an operator, while the second face 18, or blind face, is not accessible.
    Preferably, the first 16 and second 18 faces belong to at least two distinct structural elements. Said structural elements are for example metallic or made of composite materials. To simplify, a single structural element is shown in FIGS. 1 to 4.
    The structure 12 further comprises a bore 20 opening onto each of the first 16 and second 18 faces. The bore 20 is arranged along a first axis 22 substantially perpendicular to the first 16 and second 18 faces.
    The bore 20 has a milled surface 24, adjacent to the first face 16, and a cylindrical surface 26, adjacent to the milled surface and extending from to the second face 18. The milled surface 24 has a substantially frustoconical shape .
    The fixing rivet 14 is capable of joining the structural elements forming the structure 12. Said rivet comprises a screw 30 and a socket 32, intended to be inserted in the bore 20. Preferably, the screw 30 and the socket 32 are metallic, for example stainless steel of the A286 type, or a titanium alloy.
    The screw 30 has a threaded portion 36, a barrel 38 and a head 40, aligned along a second axis 34. A first end 41 of the screw 30, along said second axis 34, is formed by a free end of the threaded portion 36 The screw 30 further comprises a gripping element 42, adjacent to the head 40 and forming a second end of the screw 30 along the second axis 34.
    In the embodiment of FIGS. 1 to 4, the head 40 is a countersunk head, intended to be flush with the first face 16 of the structure 12 in the installed configuration of FIG. 4.
    The barrel 38 of the screw has a first 44 and a second 46 portions, connected by a shoulder 48. Each of the first 44 and second 46 portions has a substantially cylindrical shape of revolution, arranged along the second axis 34.
    The first portion 44 is adjacent to the head 40 and has a first diameter 50. The second portion 46 is adjacent to the threaded portion 36 and has a second diameter 52, less than the first diameter 50. As an indication, the second diameter 52 is between 80% and 95% of the first diameter 50.
    The shoulder 48 between the first 44 and second 46 portions preferably forms a gradual transition between the first 50 and the second 52 diameter. The shoulder 48 has for example a frustoconical or curved shape.
    The rivet 14 has a maximum clamping capacity G max (Fig. 2), which corresponds to the maximum thickness of the structure 12 that the rivet 14 can assemble. This maximum clamping capacity G max is represented by a length of the head 40 and of the barrel 38 along the second axis 34, up to a limit 54 of the threaded portion 36.
    Likewise, the rivet 14 has a minimum clamping capacity G min (Fig. 2), which corresponds to the minimum thickness of the structure 12 that the rivet 14 can assemble. In the embodiment of Figures 1 to 4, the thickness of the structure 12 along the first axis 22 is between G max and G min .
    In the state of the art, the minimum clamping capacity G min is defined by the manufacturer but is not necessarily materialized by a marking on the rivet. In the context of the present invention, a length of the second portion 46 of the barrel 38, along the second axis 34, is preferably chosen so as to correspond to a difference between G max and G min . The maximum and minimum tightening capacities of the rivet 14 are therefore apparent on the screw 30.
    The gripping element 42 of the screw 30 is able to cooperate with a setting tool for an automated installation of the fixing rivet 14. The gripping element 42 comprises for example a first 56 and a second 58 gripping portions, connected by a blocking portion 60. The first 56 and second 58 gripping portions and the blocking portion 60 are intended respectively to guide the introduction of the rivet 14 into a setting tool, to transmit a torque and to limit movement axial of the rivet in the setting tool. A rivet comprising such a gripping element, as well as its cooperation with a setting tool, are notably described in the document FR3016617.
    The gripping element 42 is connected to the head 30 by a rupture groove 62. Said groove is in particular configured so as to support a certain level of tensile stress along the second axis 34, and to yield beyond a certain torsional stress threshold around said second axis.
    The sleeve 32 has a tubular shape, arranged along a third axis 63 and open to a first 64 and to a second 65 ends. In the initial configuration of FIG. 1, a total length of the sleeve along the third axis 63, between the first 64 and second 65 ends, is substantially equal to a sum of the lengths of the threaded portion 36, of the barrel 38 and of the head 40 of screw 30.
    The socket 32 comprises a threaded portion 66, a smooth body 68 and a flared collar 70, aligned along the third axis 63.
    The threaded portion 66, one free end of which forms the first end 64, is able to cooperate with the threaded portion 36 of the screw 30. Preferably, near the first end 64, the threaded portion 66 has a chamfer 71 to facilitate its introduction into bore 20.
    The collar 70, one free end of which forms the second end 65, is capable of receiving the head 40 of the screw 30. The collar 70 is radially projecting from the smooth body 68. In the embodiment of FIGS. 1 to 4 , the collar 70 has a substantially frustoconical shape, complementary to the countersunk head 40.
    The smooth body 68 has an external surface 72 and an internal surface 74. In the initial configuration of FIG. 1, each of the external 72 and internal surfaces 74 has a cylindrical shape of revolution around the third axis 63.
    Preferably, a diameter of the internal surface 74 is slightly greater than the first diameter 50 of the first portion 44 of the barrel 38, so as to provide a small clearance between said barrel 38 and the smooth body 68. Likewise, a diameter of the external surface 72 is slightly less than the diameter of the cylindrical surface 26 of the bore 20, so as to provide a small clearance between said surfaces.
    As a variant, a diameter of the external surface 72 is slightly greater than the diameter of the cylindrical surface 26 of the bore 20, so as to provide a negative clearance between said surfaces.
    Preferably, a maximum diameter of the threaded portion 36 is less than or equal to the first diameter 50 of the first portion 44 of the barrel 38, so as to ensure the existence of a small clearance between said threaded portion 36 and the smooth body 68 at least. in the initial configuration of the rivet. By "maximum diameter" is meant a diameter corresponding to the crests of the threads. The thread complies for example with standard AS8879, in which the thread crests are truncated. To ensure the existence of a small clearance between said threaded portion 36 and the smooth body 68 in all the configurations of the rivet, the crests of threads of the screw can be more truncated compared to standard AS8879, the threading of the sleeve. remaining compliant with the thread of standard AS8879.
    To facilitate the manufacture of the screw, the diameter before rolling of the threaded portion is equal to the second diameter 52. Thus, the screw before rolling comprises a first portion 44 having a first diameter, and a second portion extending up to 1 end of the screw having a second diameter less than the first diameter, and identical over the entire length of the second portion. After rolling the end, the threaded portion 36 obtained has a flank diameter equal to the second diameter 52.
    As a variant, the maximum diameter of the threaded portion 36 is less than or equal to the second diameter 52 of the second portion 46 of the barrel 38, so as to ensure the existence of a small clearance between said threaded portion 36 and the smooth body 68 in all the rivet configurations. The thread of the screw and the tapped portion of the socket can comply with standard AS8879. In this embodiment, it should be ensured that the minimum diameter of the threaded portion 36 of the screw, measured at the bottom of the threads, and the number of threads is sufficient to withstand the tensile force printed on the screw.
    The smooth body 68 comprises a clamping zone 76 and a deformation zone 78, aligned along the third axis 63. The clamping zone 76, adjacent to the flange 70, is in particular capable of receiving the barrel 38 of the screw 30. The deformation zone 78, between the clamping zone 76 and the threaded portion 66, preferably has an elastic resistance lower than the elastic resistance of the rest of the bush 32. This low elastic resistance is for example obtained by selectively annealing the deformation 78, by means of an induction machine, after the formation of the sleeve 32.
    The deformation zone 78 is able to form an external bulb 80 in contact with the second face 18 of the structure 12, in particular in the installed configuration of FIG. 3.
    A method of installing the assembly 10, comprising the formation of the outer bulb 80, will now be described.
    First, the screw 30 and the socket 32 are assembled to form the fixing rivet 14. More specifically, the first end 41 of the screw 30 is introduced into the socket 32, on the side of the flange 70; then the threaded portion 36 of the screw 30 is screwed into the threaded portion 66 of the socket 32, until the head 40 of the screw comes into abutment against the flange 70, of complementary frustoconical shape.
    The fixing rivet 14, in the initial configuration of FIG. 1, is thus formed. The first end 41 of the screw 30 is close to the free end 64 of the threaded portion 66.
    The following steps are for example carried out using a setting tool engaged with the gripping element 42 of the screw 30, in a manner analogous to the method described in document FR3016617.
    The fastening rivet 14 in initial configuration is introduced into the bore 20 from the first accessible face 16 of the structure 12. The rivet 14 is moved along the first axis 22, until the flange 70 is brought into abutment of the sleeve 32 against the frustoconical surface 24 of said bore.
    The assembly 10 is thus formed, in the initial configuration of FIG. 1. The first 22, second 34 and third 63 axes are combined. The free end 65 of the collar 70 of the sleeve 32, as well as the rupture groove 62 of the screw 30, are flush with the first accessible face 16 of the structure 12. The threaded portion 66 and the deformation zone 78 of the sleeve 32, as well as the threaded portion 36 of the screw 30, form a projection outside the structure 12, on the side of the second blind face 18.
    The sleeve 32 is then held in place in the bore 20, for example by exerting an axial thrust against the end 65 of the flange 70. Simultaneously, an axial traction is exerted on the screw 30, so as to bring the structure closer 12 the first end 41 of said screw. The threaded portion 66 of the sleeve is driven by the displacement of said first end 41, which induces plastic deformation of the deformation zone 78. Said plastic deformation leads to the outer bulb 80 formed against the second surface 18.
    The assembly 10 is then in the intermediate configuration of FIG. 2. The external bulb 80 and the second face 18 on the one hand, and the flange 70 and the frustoconical surface 24 on the other hand, form opposite stops which axially block the sleeve 32 in the bore 20. The total length of the sleeve 32, between the first 64 and second 65 ends, is less than the total length of the sleeve in the initial configuration. Furthermore, in the intermediate configuration, the external bulb 80 of the sleeve is located opposite the threaded portion 36 of the screw.
    The formation of the outer bulb 80, by plastic deformation of the deformation zone 78, causes a slight deformation of the clamping zone 76 near said bulb. In particular, after the formation of the external bulb 80, the clamping zone 76 has an internal bulge 82 near said external bulb. At the level of said internal bulge 82, the internal surface 74 has a diameter less than the diameter of said internal surface 74 in the rest of the clamping zone 76.
    When the maximum diameter of the threaded portion 36 is less than or equal to the first diameter 50 of the first portion 44 of the barrel, and greater than the second diameter 52 of the second portion 46 of the barrel 38, it can happen, depending on the thickness of the sleeve, of the material of the sleeve and / or of the tensile force imparted to the screw, that the internal bulge 82 comes into contact with a crest of the thread. This contact is not penalizing for the installation of the rivet because the contact surfaces are small, the thread having in essence a helical surface. One way to reduce the risk is to truncate the crest.
    The next step in the installation process is to screw the threaded portion 36 of the screw 30 into the threaded portion 66 of the socket 32. The screw 30 moves axially inside the socket 32, until that the head 40 comes into abutment against the flange 70. If the internal bulge 82 comes into contact with a crest of the thread, this thread will slightly tap the bulge without inducing torque in the socket.
    Finally, a twist is exerted on the gripping element 42 so as to break the screw 30 at the level of the rupture groove 62. The assembly 10 is then in the installed configuration, represented in FIG. 3 without the element of grip 42.
    In the installed configuration, the internal bulge 82 of the sleeve 32 is opposite the second portion 46 of the barrel 38 and / or the threaded portion 36.
    More specifically, in the case where the structure 12 has a thickness close to the minimum clamping capacity G min , the internal bulge 82 is located opposite the second portion 46 and possibly the shoulder 48. The second portion 46 is essentially protruding from the structure 12.
    In the case where the structure 12 has a thickness close to the maximum clamping capacity G max , the internal bulge 82 is located opposite the second portion 46 and the limit 54 of the threaded portion 36. The second portion 46 is essentially received inside the bore 20.
    The second diameter 52 of the second portion 46 of the barrel 38 is configured so as to avoid seizing of the rivet 14 during the screwing step leading to the installed configuration. Preferably, the second diameter 52 is chosen so as to provide a radial space 84 (FIG. 4) between the second portion 46 and the internal bulge 82 of the sleeve.
    Thus, the internal bulge 82 does not interfere with the screwing step after formation of the external bulb 80. In particular, it is not necessary to apply to the screw a higher screwing force at the end of said screwing step , before bringing the head 40 into contact with the flange 70.
    Another advantage linked to the second portion 46 of reduced diameter compared to the first portion is that it eliminates any risk of the sleeve being driven in rotation during the step of inserting the screw into the socket. Indeed, if the clearance between the inside of the sleeve and the barrel is very small, the contact between the barrel of the screw and the internal bulge 82 is made around the entire periphery of the barrel and the bulge. The friction induced by the rotation of the screw in the bushing will then be greater the greater the contact surface between the two elements.
    In comparison, a screw with a barrel having a single diameter equivalent to the first portion, maximized to increase the shear strength of the rivet, will therefore present a high risk of rotation of the sleeve.
    In another comparison, a screw provided with a barrel having a single diameter equivalent to the second portion making it possible to eliminate any risk of driving the bush in rotation, will have the disadvantage of having a lower shear strength.
    According to a variant (not shown) of the embodiment of Figures 1 to 4, the head 40 of the screw 30 is a protruding head, intended to form a projection relative to the first face 16 of the structure 12. The bore 20 then has a cylindrical shape devoid of a milled surface 24. The flange 70 of the sleeve 32 is substantially planar and bears against the first face 16 of the structure 12. According to this variant, the length of the head 40 is not included in the maximum G max and minimum G min tightening capacities of the fixing rivet 14.
