    Description
    Title of the invention: Connection device for a fluid supply system [0001] The present invention relates to the field of connection devices for connecting an air supply to a pneumatic system, such as a pneumatic system making part of an assembly station for a vehicle body part.
    History of the Invention In order to supply air to a pneumatic device of an assembly station in the automotive industry, it is well known to connect the pneumatic device to the air supply to using a tube, the nozzle of which is connected to a fluid outlet orifice in the air supply. To do this, the nozzle must be aligned with the hole. Such alignment is generally carried out by a human operator capable of positioning the nozzle manually in front of the orifice in a sufficiently precise manner, by checking the alignment visually.
    However, in the context of the automotive industry, most assembly work is now carried out automatically, using robots or other remotely controlled devices, in order to increase productivity. It is therefore desirable to avoid the intervention of a human operator to connect the nozzle to the orifice. To do this, the hole must be configured so that it is possible to insert a nozzle without requiring a high level of precision when aligning the nozzle with the hole.
    The invention aims to remedy this problem by proposing a connection device for a fluid supply system comprising a female connection part and a male connection part, characterized in that the female connection part comprises:
    - a rear support plate;
    - an intermediate support plate;
    - a front support plate;
    Wherein said front support plate comprises a fluid outlet orifice designed to be connected to a corresponding connection element of the male connection piece, and each of said rear, intermediate and front support plates comprises an outlet hole connected to the outlet;
    Wherein the intermediate support plate is fixed to the rear support plate and the front support plate is fixed to the intermediate support plate;
    Wherein the front support plate is configured so as to be able to move along a first axis;
    Wherein the intermediate support plate is configured so as to be able to move along a second axis, the second axis being transverse to the first axis.
    Given the fact that the front and intermediate support plates can move along two transverse axes relative to each other, they form floating plates capable of moving relative to the rear support plate in two different directions, that is to say that they can be pivoted and / or slightly displaced in order to be able to insert the male part into the fluid outlet orifice without requiring precise alignment between them. In other words, an alignment tolerance is therefore obtained. This allows a robot or a remotely controlled device to insert the male part into the fluid outlet orifice and make the connection, thus making the intervention of a human operator superfluous.
    Summary of the invention In a preferred embodiment, the front support plate is screwed to the intermediate support plate using at least one screw, the front support plate comprising an oblong hole extending along the first axis and in which the intermediate support plate is screwed to the rear support plate using at least one screw, the intermediate support plate comprising an oblong hole extending along the second axis . This simple and nevertheless effective configuration allows the front and intermediate support plates to move along the first and second axes.
    Preferably, the connection device further comprises a support frame framing the rear, intermediate and front support plates, in which the intermediate support plate is connected to the support frame by at least two springs extending the along the second axis, preferably four springs, and in which the front support plate is connected to the support frame by at least two springs extending along the first axis, preferably four springs.
    The use of a support frame to hold the plates by means of springs allows the intermediate plates and before being pushed back to their initial position, once the connection has been made.
    In a preferred embodiment, for each spring, a spring support pin extends from the support frame through at least one of the turns of the spring and / or a retaining ring surrounds at least one of the turns of the spring which is fixed to the frame, in order to stabilize the spring.
    This makes it possible to prevent the rings from moving to the left and to the right and to rotate the plates inappropriately.
    In a preferred embodiment, the first and second axes are perpendicular to each other. This is particularly suitable for square plates which are easily integrated into a connection device.
    In a preferred embodiment, the female connection piece further comprises at least two guide pins for guiding the insertion of the male connection piece into the female connection piece, the male connection piece comprising in addition to at least two corresponding guide holes designed to receive the guide pins, the holes being bevelled so as to facilitate the insertion of the pins into the holes.
    In a preferred embodiment, in the plane of the front support plate, the guide pins are aligned with the fluid outlet orifice. This alignment helps prevent improper pivoting of the plates.
    In order to protect its parts, which is generally necessary in environments such as auto parts assembly plants, the connection device preferably further comprises a protective cover covering the rear, intermediate and support parts. front as well as the guide pins.
    In a preferred embodiment, the protective cover is connected to the support frame and is configured to move relative to the support frame in a direction of insertion of the male connection piece into the female connection piece .

    Figure 5 is an exploded view of the male connection piece of a connection device according to a preferred embodiment of the invention.
    Detailed description of the invention [0032] Figure 1 shows a female connection piece 12 of a connection device 10 for a fluid supply system comprising a male connection piece 14 shown in Figure 5. An exploded view of the male connection part 14 is shown in FIG. 3.
    In the preferred embodiment of the invention shown in the figures, the connection element of the female connection piece 12 is connected to an air supply system 15 of an assembly station of vehicle part (not shown), while the male connection part 14 is connected to said vehicle part assembly station.
    The female connection piece 12 comprises a rear support plate 16, an intermediate support plate 18 and a front support plate 20. Each of these plates is of substantially square shape, but of course other shapes can be envisaged, such as rectangular, round or even triangular shapes. Preferably, all the plates have the same size, in other words either the same side length in the case of a square or triangular plate, or the same diameter in the case of a round plate.
    The front support plate 20 comprises a fluid outlet orifice 22 connected to a corresponding connection element 23 of the male connection piece 14. The fluid outlet orifice 22 is preferably arranged in the center of the plate front support 20.
    The rear support plates 16, intermediate 18 and front 20 each comprise an outlet hole 16a, 18a, 20a connected to the outlet orifice 22. Preferably, they are aligned in the direction of insertion of the part male connection 14 in the female connection piece 12. In the present case, all the outlet holes are formed in the center of the plates 16, 18, 20 and share a common center. In the present case, the outlet holes 16a and 18a are circular while the outlet hole 20a is of substantially square shape.
    The intermediate support plate 18 is fixed to the rear support plate 16 and the front support plate 20 is fixed to the intermediate support plate 18.
    The front support plate 20 is screwed to the intermediate support plate 18 using two screws 24. The front support plate 20 comprises in particular two oblong holes 20b extending along a first axis YY through which the screws 24 pass, respectively. The front support plate 20 can thus move along said first axis Y-Y.
    In the present case, the first axis YY is substantially parallel to one of the sides of the front support plate 20. Taking into account the orientation of the front support plate 20 in FIGS. 2 and 3, the first axis YY corresponds to the vertical axis of the figures. Screws 24 are inserted into corresponding holes 24a formed in the intermediate support plate 18.
    Oblong holes 20b have a substantially elongated shape. They are preferably located on two opposite sides of the front support plate 20 symmetrically with respect to the outlet hole 20a.
    Similarly, the intermediate support plate 18 is screwed to the rear support plate 16 using two screws 26. The intermediate support plate 18 comprises an oblong hole 16b extending along a second axis XX through which the screws 24 pass. The front support plate 20 can thus move along said second axis XX.
    Oblong holes 16b have a substantially elongated shape. They are preferably located on two opposite sides of the front support plate 20 symmetrically with respect to the outlet hole 18a.
    The intermediate support plate 18 is configured so as to be able to move along a second axis X-X. The second axis X-X is transverse to the first axis Y-Y. In a preferred embodiment, as shown in the figures, the first axis Y-Y and the second axis X-X are perpendicular to each other. Thus, taking into account the orientation of the front support plate 20 in FIGS. 2 and 3, the second axis X-X corresponds to the horizontal axis of the figures.
    Given that the front support plates 20 and intermediate 18 can move along two transverse axes relative to each other, they form floating plates capable of moving relative to the support plate rear 16 in two different directions, that is to say that they can be pivoted and / or slightly displaced in order to be able to insert the male part 14 into the fluid outlet orifice 22 without requiring precise alignment between them.
    The connection device further comprises a support frame 30 framing the rear support plates 16, intermediate 18 and front 20. Given the square frame of the support plates 16, 18, 20, the support frame is hollow square cuboid shape.
    The intermediate support plate 18 is connected to the support frame 30 by at least two springs extending along the same axis as the oblong hole 18b, that is to say along the second axis X-X. In the preferred embodiment shown in the figures, the intermediate support plate 18 is connected to the support frame 30 by four horizontal springs 32.
    Similarly, the front support plate 20 is connected to the support frame 30 by at least two springs extending along the same axis as the oblong hole 20b, that is to say along the first axis YY . In the preferred embodiment shown in the figures, the front support plate 20 is connected to the support frame by four vertical springs 34.
    The support frame 30 comprises, for each spring 32, 34, a corresponding spring support pin 32a, 34a, extending from the support frame 3 through at least one of the turns of the spring 32, 34, so to stabilize the spring 32, 34, for example the first turn or the two first turns. The support frame 30 further comprises, for each spring 32, 34, a retaining ring 32b, 34b surrounding at least one of the turns of the spring 32, 34 which is fixed to the frame 30, for example the first turn, in order to stabilize the spring 32, 34.
    As shown in Figures 4 and 5, taking into account that the front support plate 20 and the intermediate support plate 18 are connected to each other, to the rear support plate 16 and to the frame support 30 as described above, the fluid outlet orifice 22 can be moved in the plane containing the two axes XX and YY as much as the springs allow.
    Figure 4 illustrates a so-called neutral position, or rest, in which the springs 32, 34 are at rest. In this rest position, the intermediate support plates 18 and before 20 are both centered in the support frame 30.
    FIG. 5 illustrates an extreme position in which the intermediate support plate 18 and the front support plate 20 have both been moved along the axes X-X and Y-Y, respectively, as far as the springs 32, 34 allow them.
    It will be understood that the intermediate support plate 18 and the front support plate 20 can take any position in the plane containing the two axes XX and YY, within the limits defined by the tension and the length of the springs 32 , 34.
    Misalignment between the male connection piece 14 and the female connection piece 12 can thus be tolerated.
    For example, when the male connection part 14 is positioned in front of the female connection part 12, it can be inserted into the female connection part 12 even if the male connection element 23 is not aligned with the center of the fluid outlet orifice 22, for example if it is slightly displaced to the right, the intermediate support plates 18 and front 20 can be slightly displaced to the right.
    The female connection piece 12 further comprises two guide pins 36 for guiding the insertion of the male connection piece 14 into the female connection piece 12. In the preferred embodiment shown in the figures, the two guide pins 36 extend from the front support plate 20, moving away from the front support plate 20, in a direction substantially perpendicular to the plane of the front support plate 20.
    Preferably, the guide pins 36 extend from two opposite angles of the front support plate 20. Even more preferably, the guide pins 36 and the outlet orifice 22 are aligned in the plane of the front support plate 20.
    The male connection part 14 comprises two corresponding guide holes 38 designed to receive the guide pins 36, the guide holes 38 being bevelled so as to facilitate the insertion of the pins 36 in the guide holes 38.
    More particularly, the male connection part 14 comprises a male body 40 to which is fixed a male retaining plate 42 relative to which the male connection element 23 is projecting. Like the female plates 16, 18, 20, the male retaining plate is square, but other forms could be envisaged.
    The male connection part 14 further comprises a male front plate 44, screwed to the male retaining plate 42. The male retaining plate 42 comprises the male connection element 33 relative to which it projects. The male front plate 44 is also square in the present preferred embodiment. The guide holes 38 are formed in the male front plate 44. Preferably, the guide holes are located on two opposite corners of the male front plate 44. The male front plate 44 also has a central hole 45 intended to receive the male connection element 23.
    The connection device 10, in particular the female connection piece 12, further comprises a protective cover 50 covering the rear support plates 16, intermediate 18 and front 20 as well as the guide pins 36. Given the square frame of the support plates 16, 18, 20, the protective cover is of hollow square cuboid shape.
    The protective cover 50 extends on at least one side of the rear support plate 16 until, on the other side, at least the free end of the guide pin 16.
    The protective cover 50 is connected to the support frame 30 and is configured to move relative to the support frame 30 in a direction of insertion of the male connection piece 14 into the female connection piece 12.
    Optionally, the connection device 10 further comprises a sensor (not shown) capable of detecting that the female 12 and male 14 connection parts have been connected and / or disconnected.
    The invention is not limited to the embodiments presented and other embodiments will be apparent to those skilled in the art.
