    [0001] TECHNICAL FIELD The present invention relates to the field of assembly of aircraft fuselage panels and more particularly to a method and a system for assembling a plurality of panels. fuselage of an aircraft by welding, including the front tip of the fuselage of an aircraft.
    [0002] STATE OF THE ART The nose tip of the fuselage of an aircraft is manufactured in known manner by the assembly edge to edge of a plurality of panels.
    [0003] To do this, the edges of the panels to be joined are first machined separately and then welded together. The machining of the edges to be joined makes it possible to eliminate the superfluous material resulting from the manufacture of the panels and to smooth the edges in order to improve the quality and the regularity of the junction between two panels. The panels being machined one after the other independently, the edges of two panels to join together are not necessarily complementary. This results in a clearance between the edges of the panels, which is variable along the junction and all the more so as the panels are bent. Such a game degrades the quality, efficiency and aesthetics of the weld, which has a first disadvantage. In addition, the method of assembling curved panels can be complex, tedious and time-consuming since each panel must be machined independently on a worktable, the panels moved on a welding table, positioned side-to-side and solder, which has a second major disadvantage.
    [0004] GENERAL PRESENTATION OF THE INVENTION The object of the invention is therefore to remedy these drawbacks by proposing a workpiece support system for assembling a plurality of fuselage panels of an aircraft which is at the same time simple, effective, reliable and quick to implement. To this end, the invention relates to a system for assembling a plurality of fuselage panels of an aircraft, said system comprising at least one anvil body, at least a first panel and a second panel, and moving means mounted on said anvil body, said moving means being arranged to move the first panel relative to the second panel between a first machining position in which an edge of the first panel and an edge of the second panel are spaced apart from a machining distance so as to allow the passage of a machining tool between said edges for machining them simultaneously and a second welding position in which said edge of the first panel and said edge of the second panel are adjacent and bearing on said anvil body. According to the invention, the same system can therefore be advantageously used both for machining and welding the edges to be joined of a plurality of panels without having to be manipulated once they have been positioned on the device. . In addition, such a system allows to machine or weld several panels simultaneously, which makes their assembly both easy and fast.
    [0005] The machined edges of the first panel and the second panel are complementary in that they have been machined at the same time and by the same tool, which makes it possible to avoid excessive play between the edges to be joined. panels and thus achieve a welding that is both solid and aesthetic.
    [0006] It will further be noted that when the panels comprise a coating which it is necessary to remove at the edges to be joined in order to allow them to be welded, the displacement means are arranged to move the first panel relative to the second panel in a third stripping position in which an edge of the first panel and an edge of the second panel are spaced a stripping distance so as to allow the passage of a tool stripping said coating on said edges to strip them simultaneously. According to one characteristic of the invention, the displacement means comprise a mobile support on which the first panel is positioned. Preferably, the displacement means comprise two movable supports so as to allow the assembly of three fuselage panels simultaneously, for example in order to assemble a lower part of a front tip of an aircraft. More preferably, the moving means is configured to move the first panel laterally and vertically. Preferably, the means for moving the first panel relative to the second panel comprises a mechanism for guiding the mobile support with respect to a first lateral portion of the anvil body. Advantageously, the mobile support comprises means for holding the edge of said first panel. According to one characteristic of the invention, the holding means comprise at least one suction table. According to another characteristic of the invention, the first panel is curved. According to one aspect of the invention, the anvil body has an upper support surface of curved shape so as to conform to the shape of an aircraft nose. Advantageously, the system comprises means for positioning the panels so as to increase the precision and the quality of the assembly. Such positioning means may be, for example, in the form of a plurality of pins and complementary bores. According to one characteristic of the invention, positioning means are mounted on the movable support (s).

    [0008] Preferably, the holding means comprise a plurality of suction cups, preferably disposed both on the anvil body and on the one or more movable supports and arranged to hold the first panel and the second panel.
    [0009] More preferably, the holding means comprise at least one suction table each arranged to receive an edge to join a panel. In a preferred aspect, the anvil body includes two suction tables.
    [0010] According to one characteristic of the invention, the suction table or tables comprise means of heat dissipation, for example a radiator comprising aluminum blades. In a preferred embodiment of the device, the anvil body comprises at least one anvil rail, preferably two anvil rails, movably mounted in a cavity of the anvil body. The anvil rail is configured to move between a high position in which the upper surface of the anvil rail extends in the extension of the anvil body support surface and a low position in which a work space is created between the upper surface of the anvil rail anvil rail and the anvil body support surface so as to allow the passage of a machining and / or stripping tool.
    [0011] According to one characteristic of the invention, the anvil rail comprises a beam of structure, preferably metal, extending over the entire length of the anvil body.
    [0012] Preferably, the anvil rail comprises heat dissipation means, for example a radiator comprising aluminum blades, preferably mounted on the lower part of the structural beam. Advantageously, the structural beam comprises two support ribs 10 of the first panel and the second panel acting as robust counter-support for the welding of their edges and further allowing to guide a tool holder so that a tool can move along the anvil rail. Advantageously again, the structural beam comprises a tool holder and a guide rail of said tool holder. According to a preferred aspect of the invention, the guide ramp extends along the length of the structural beam and laterally to the latter so as to allow the movement of the tool holder along the structural beam over the length of the structural beam. edges 20 to be joined. The tool holder may include a deflectometer so as to control an operation performed by the machining tool and / or the stripping tool on the edges to join panels.

In the machining position, the joining edges of two panels are spaced at a machining distance of preferably between 0 and 5 mm. In the etching position, the edges to be joined of two panels are spaced apart by a pickling distance preferably between 0 and 1 mm.
    [0013] In the welding position, the joining edges of two panels are disposed edge to edge with a clearance between said edges less than 0.5 mm. The invention also relates to a method of assembling a plurality of fuselage panels of an aircraft, in particular implemented by a system as presented above, for securing said panels two by two by one of their edges, said method being remarkable in that it comprises a step of positioning a first panel and a second panel so that their edges to be joined are arranged opposite one another and separated from one another. machining distance, a step of machining said edges simultaneously by means of a machining tool passing between said edges, an edge-to-edge positioning step of the first panel and the second panel in a welding position, and a step of welding the edges of the first panel and the second panel.

DESCRIPTION OF A PREFERRED EMBODIMENT The system according to the invention comprises an assembly device on which a plurality of panels to be assembled are arranged. 1) Device 1 Figures 1 to 10 describe a preferred embodiment of the device according to the invention which allows the assembly of three panels 2, 3 and 4 fuselage of an aircraft simultaneously, in particular, a central panel 3 , a first side panel 2 and a second side panel 4. For this purpose and according to the invention, the device 1 comprises an anvil body 10, first displacement means mounted on said anvil body 10 and adapted to moving the first side panel 2 relative to the central panel 3 and second moving means mounted on said anvil body 10 and adapted to move the second side panel 2 relative to the central panel 3. Subsequently, it refers to assembly system the assembly device 1 equipped with its panels 2, 3 and 4. a) Anvil body 10 In this example, as illustrated in particular in FIG. 1, the anvil body 10 is in the form of an armatu structural reinforcement comprising a rectangular base 11 resting on reinforcements 12 and on which is mounted a plurality of vertical stiffeners 13 arranged in parallel and interconnected by horizontal stiffeners 14, thus defining a plurality of caissons 15. 15 Anvil body 10 has an upper support surface of curved shape to fit the shape of an aircraft nose, but it goes without saying that the shape of the support surface could be different depending on the destination of the panels to be assembled. Referring to Figure 1, the anvil body 10 has a central portion 10b and two side portions 10a and 10c for respectively supporting the central panel 3 and the side panels 2, 4. A plurality of suction cups 16 are disposed in the boxes 15 of the central part of the anvil body 10 so as to maintain the central panel 3 fixedly relative to the anvil body 10. In addition, in order to position the central panel 3 on the device 1, the anvil body 10 comprises means for positioning said panel 3 in a predetermined position in order to perform the machining and welding steps. Such positioning means are in this example in the form of pins 18 configured to be received respectively in bores formed in the central panel 3 so as to maintain it in the predetermined fixed position with respect to the anvil body 10 as illustrated in Figure 3.
    [0015] In this example, the anvil body 10 comprises two anvil rails 20 mounted respectively movable in two cavities 17 of the anvil body 10 (with reference to Figures 3, 4 and 6). Each anvil rail 20 is configured to move between a high position PH, as illustrated in FIGS. 4 to 6, wherein the upper surface of the anvil rail 20 extends in the extension of the body support surface of an anvil 10 and a low position PB, illustrated in FIG. 4, in which an ESP workspace (with reference to FIGS. 2 and 4) is created between the upper surface of the anvil rail 20 and the support surface of the body of Anvil 10. As will be presented later, such ESP workspace allows the passage of a machining tool and / or stripping 50 as shown in Figures 5 and 6. An anvil rail 20 will henceforth The anvil rail 20 comprises a structural beam 21, preferably a metal beam, extending over the entire length of the anvil body 10. In this example, the beam is shown in FIGS. of structure 21 is elongate and curved so as to extending in the extension of the support surface of the anvil body 10 in the welding position. As illustrated in FIG. 5, the structural beam 21 comprises two ribs 22 for supporting the panels 2, 3 and 4 and a guide ramp 23 for a tool holder 24. The structural beam 21 is dimensioned to withstand forces compressive welding, in particular friction stir welding, panels 2, 3 and 4.
    [0016] The guide ramp 23 extends along the length of the structural beam 21 and laterally to the latter as illustrated in FIG. 5. The guide ramp 23 comprises a toothed surface 23a adapted to cooperate with a toothed wheel 24a of the carrier. tool 24 to form a rack system for moving the tool holder 24 along the structural beam 21 to machine, strip and / or weld the panels 2, 3 and 4 with the aid of a machining and / or pickling tool 50 mounted on the tool holder 24.
    [0017] The tool holder 24 is preferably driven by drive means (not shown) comprising for example a motor adapted to rotate the toothed wheel 24a. Thus, it is sufficient for an operator to control said motor in order to modify the position of the tool holder 24 on the anvil rail 20.
    [0018] The tool holder 24 further comprises a deflectometer 25 so as to control an operation performed by the tool 50 on the edges of panels 2, 3 and 4, in particular to control the quality of a pickling operation.
    [0019] Alternatively, the anvil body 10 may be in one piece so as to provide a continuous upper support surface. In other words, the anvil body can be devoid of cavities 17 and anvil rails 20. The function of the anvil body 10 is to be a single positioning reference system 15 for the panels 2, 3 and 4 during their different assembly steps to ensure accurate assembly. In this example, the anvil body 10 comprises a positioning module of the central panel 3 which is in the form of two suction tables 32 adapted to block the position of the central panel 3. A suction table, well known to the A person skilled in the art can draw a surface of an object in order to keep it pressed onto said table so as to be able to work it, for example to machine it, strip it or weld it. As illustrated in particular in Figures 1 and 2, each suction table 32 is in this example in the form of a pad of length at least equal to that of the panel to maintain and conforming to the shape thereof. b) Means of displacement The first means of displacement of the first side panel 2 relative to the central panel 3 comprise a first support 31 adapted to receive the first side panel 2 and a guide mechanism 34 of the first support 31 relative to a first lateral portion 10a of the anvil body 10.
    [0020] Similarly, the second displacement means of the second lateral panel 4 with respect to the central panel 3 comprise a second support 33 adapted to receive the second lateral panel 4 and a guide mechanism 34 of the second support 33 relative to a second lateral part. 10c of the anvil body 10.
    [0021] The two movable side panel supports 31 and 33 are each in the form of a curved structural reinforcement while the guiding mechanisms 34 comprise a set of rails and grooves allowing the supports 31, 33 to slide relative to the Anvil body 10. Preferably, each guide mechanism 34 includes a worm to adjust the slide and a control wheel 40 adapted to be manipulated by an operator (not shown) to rotate said worm. It goes without saying that other guiding mechanisms could also be suitable (rack, cylinder, etc.). It goes without saying that the control of the movement can be manual or motorized. The armature of the supports 31, 33 is similar to that of the anvil body 10 and thus defines a plurality of boxes 37. Thanks to the first displacement means and the second displacement means, the lateral panels 2, 4 are arranged to move between a machining position, illustrated in Figure 9, and a welding position, illustrated in Figure 10. In machining position, a machining distance exists between each side panel 2, 4 25 and the stationary central panel 3 so that each pair of edges to join panels (2, 3) and (3, 4) is able to be machined simultaneously with the same machining tool. The machining position may also correspond to a stripping position in which a coating applied to the panels 2, 3 and 4 can be removed with the aid of a stripping tool.
    [0022] In the welding position, the movable panel supports 31 and 33 are moved so that the edges of the panels (2, 3) and (3, 4) are adjacent in pairs so that they can be welded together with a welding tool.
    [0023] In order to position the side panels 2, 4 on the supports 31, 33, the latter comprise means for positioning the panels 2 and 4 in a predetermined position in order to perform the machining and welding steps. As illustrated in FIG. 3, such positioning means are in this example in the form of a plurality of pins 38 configured to be received respectively in bores formed in the side panels 2, 4 so as to maintain them in the predetermined position on the supports 31, 33. Preferably, as shown in Figure 1, the supports 31, 33 each comprise a plurality of suction cups 39a for stably maintaining the side panels 2, 4 during assembly.
    [0024] Each of the supports 31, 33 comprises a suction table 39b arranged parallel to the suction table 32 intended to hold the central panel 3 so as to receive and support the edges to be joined of the side panels 2, 4 disposed on the supports 31, 33. note finally that the suction tables 32 and 39b and the structural beam 21 20 comprise means of heat dissipation, including the heat of a friction stir welding. As illustrated in FIGS. 4 and 6, these heat dissipation means are in the form of radiators 42 comprising a plurality of heat-dissipating blades, preferably of aluminum, mounted on the lower part respectively of the suction tables 32 and 39b and of the structural beam 21. 2) Implementation The assembly of the panels 2, 3 and 4 comprises a plurality of steps, hereinafter described in particular with reference to FIG. 11, making it possible to couple them in pairs by at least one of their edges. a) Positioning the panels 2, 3 and 4 on the device 1 In order to increase the quality and precision of the assembly, the method firstly comprises a step E1 of positioning the central panel on its positioning module 32 and side panels 2, 4 on their movable supports 31, 33 with the aid of the positioning means 18, 38 so that two edges to be joined are in contact with one another. Each panel 2, 3 and 4 is kept plated by the combined action of the plurality of suction cups 16, 39a and suction tables 32 and 39b.
    [0025] Preferably, the side panels 2, 4 are positioned adjacent two by two relative to the central panel 3 during their positioning on their movable supports 31, 33. In order to carry out the machining, also called "clipping", edges to join, the movable supports 31, 33 are first spaced a machining distance from the fixed central panel 3 in a step E2 spacing E illustrated in Figure 9. The spacing is defined so the machining distance allows the passage of a machining tool between said edges to machine them simultaneously. In this exemplary implementation, the machining distance between said edges to be joined is between 0 and 5 mm. Alternatively, the positioning of the side panels 2, 4 can be directly made in machining position, spaced apart, the central panel 3. b) Machining edges to join The machining of the edges of the panels 2, 3 and 4 is realized in a step E3. In this exemplary embodiment, the machining tool is in the form of a rotary bur with a diameter of the order of 6 mm. In a first embodiment, the anvil rails 20 are placed in the low position PB and the edges to join panels are machined by a machining tool (not shown) moving above the panels 2, 3 and 4 (for example by being attached to the end of a robotic arm or on a gantry). In a second embodiment, the anvil rails 20 are also placed in the low position PB and a machining tool 50 is fixed on the tool holder 24 of each anvil rail 20 in order to perform the machining of the edges. . c) Edge stripping When the panels 2, 3, 4 comprise a coating on their lower faces (in position of the panels 2, 3 and 4 on the device 1), it is necessary to remove this coating at the edges to be joined to to improve the quality of the welding of said edges.
    [0026] To do this, the anvil rails 20 are placed in the low position PB, a stripping tool 50 is mounted on the tool holder 24 and the edges to be joined are brought together, if necessary, in a stripping position in which they are spaced from a distance of between 0 and 1 mm in order to perform this etching in a step E4.
    [0027] When the machining has been previously performed by a machining tool mounted on the tool holder 24 of the anvil rail 20 in the low position PB, the machining tool is first removed from the tool holder 24 and then a pickling tool 50 is mounted on the tool holder 24. The quality of the pickling is checked during the pickling step by the deflectometer 25 mounted on the tool holder 24. A defect detected by the deflectometer 25 can be taken up by the stripping tool 50. d) Welding 30 The machining of two edges to be joined having been carried out simultaneously by the assembly system 1, said edges has a complementarity of shape such that the clearance between the edges is advantageously very small, less than 0.5 mm, when positioned edge to edge.
    [0028] Once machined and optionally stripped, the side panels 2 and 4 and the central panel 3 are positioned edge to edge in a welding position in a step E5 R approach, as shown in Figure 10, so that the distance between the edges to be joined are less than 0.5 mm.
    [0029] If the edges to be joined have not been stripped, they are brought together in pairs by moving the movable supports 31 and 33 from the machining position to the welding position.
    [0030] If the edges to be joined have been stripped, they are brought together, if necessary, two by two by moving the movable supports 31 and 33 from the pickling position to the welding position. Before welding the panels 2, 3 and 4 in a step E6, the anvil rails 20 are placed in the high position PH so as to form an effective and solid counter-support for the panels 2, 3 and 4 during welding , especially when it is made by friction stirring. The welding is preferably carried out by friction stirring but it goes without saying that any other type of welding can be used. Once panels disposed edge to edge and resting on the ribs 22 of the anvil rails 20 in the high position PH, the panels 2, 3 and 4 are welded, preferably and advantageously simultaneously by two welding tools. The device and method according to the invention therefore advantageously make it possible to machine several panels simultaneously. More particularly, the use of a single tool for machining the edges of two panels to be welded makes them advantageously complementary and considerably reduces the clearance between said panels, which makes the weld both strong and aesthetic.
    [0031] In addition, the machining and welding of the three panels is thus advantageously very fast since it is performed on the same assembly device 1 without having to manually manipulate the panels 2, 3 and 4.
    [0032] It will be further noted that the assembly system 1 according to the invention advantageously allows simultaneous machining, stripping and welding for each pair of panels (2, 3) and (3, 4) to be assembled. Preferably, the machining and welding are performed by a tool moving above the panels 2, 3 and 4 and stripping, when it occurs, is performed by a tool 50 moving on the anvil rail 20, below the panels positioned on the device It should be noted that the present invention is not limited to the examples described above and is capable of numerous variants accessible to those skilled in the art. In particular, the shapes, the nature, the dimensions and the characteristics in terms of material of the anvil body 10, the anvil rails 20, the supports 31, 33 as represented in the figures so as to illustrate an exemplary embodiment. of the invention can not be interpreted as limiting.
