Description

Method of mounting two contiguous doors of a motor vehicle

The present invention relates to a method of mounting two adjoining doors of a motor vehicle.

The invention also relates to a placement device and a gripping device implementing such a mounting method.

The invention also relates to a motor vehicle body comprising such a mounting method.

The invention also relates to a motor vehicle comprising such a box or such a mounting method. The installation of two adjacent doors on the body of a motor vehicle must meet several objectives. First of all the assembly must allow an easy handling of the two doors, without superfluous resistance. In addition, both doors must, when closed, provide a harmonious appearance. For this, the relative placement of the two doors must comply with rules concerning the clearance between the two doors along the longitudinal axis of the motor vehicle, relating to the offset between the lower and / or upper edges of the two doors along the vertical axis, concerning the misalignment of one door relative to the other along the transverse axis and finally concerning the inclination of one door relative to the other. For this purpose, it is known to adjust the placement of each door during assembly. For this purpose, a first door, for example the rear door is placed on a rear door template itself placed relative to the body of the motor vehicle. The hinges between the rear door and the body of the motor vehicle are screwed and the caliber used for placement can be removed. The same operation is then performed on a second door, for example the front door. Such a process may lead to defects in relative placement of the two doors too important. When the play, the offset, the misalignment or the inclination between the two doors is too important, a retouching operation is performed. Retouching operations disrupt the operation of the assembly shop, can damage the hinges and are not always sufficient to correct the defects found.

Figure 12 is an example of implementing a step of placing two adjacent doors on a placement device.

Figure 1 illustrates an embodiment of a placement device 30 for placing two adjacent doors 10, 20 of a motor vehicle 1 relative to one another. The placement device is shown with the two doors 10, mounted thereon. The two doors 10, 20 can for example, left or right side doors of the motor vehicle 1. A first door, designated front door 10, may be intended to be placed at the front of the motor vehicle and a second door, designated rear door 20 may be intended to be placed at the rear of the motor vehicle. The two doors are contiguous, that is to say that they are intended to be mounted side by side on a motor vehicle and possibly without a third bodywork element interposed between the two doors over their entire height. Once mounted on a body 2 of the motor vehicle 1 and once closed, the two doors can be separated by a set 3. Each door 10, 20 comprises an inner face 17 intended to be oriented towards the inside of the motor vehicle and a outer face 18, 28 intended to be oriented towards the outside of the motor vehicle 1. The inner 17 and outer faces 18, 28 of the two doors 10, 20 extend at least approximately in a plane. Once mounted on the vehicle, the doors being closed, the plane of the outer face 18 of the front door 10 may be at least substantially parallel to the plane of the outer face 28 of the rear door 20. Once mounted on the vehicle, the doors being closed, an upper edge 13 of the front door 10 may be at least substantially aligned with an upper edge 23 of the rear door 20 and / or a lower edge 14 of the front door 10 may be at least substantially aligned with a lower edge 24 of the rear door 20 and / or a lower edge 1 6 or upper of a window 15 of the front door 10 may be at least substantially aligned with a lower edge 26 or upper of a window 25 of the rear door 20. An outline of a door is defined by the set of lower, upper, rear and front edges of the door. Once mounted on a motor vehicle, each of the two doors can open or close by a rotational movement around at least one hinge 101, 201 disposed near an edge of the door. According to the embodiment described, the front door 10 is provided with two hinges 101 disposed near a front edge 12 of the front door 10 and the rear door 20 is provided with two hinges 201 arranged near a front edge 22 of the rear door 20. Alternatively, a hinge of the front door or the rear door could be disposed near any other edge of the door. According to another variant, at least one door could be for example a sliding door, that is to say a door opening or closing by a translational movement.

A direct orthonormal coordinate system comprising the X axis, the Y axis and the Z axis is defined by reference to the two doors in the closed state. The X axis designates the longitudinal axis of the two doors in the closed state. The X axis is parallel to the longitudinal axis of the motor vehicle, that is to say the axis in which the vehicle moves in a straight line once the two doors are mounted on the motor vehicle. The X axis is oriented from the front to the rear of the motor vehicle. The left and the right are defined according to the point of view of a driver of the motor vehicle. The Y axis designates the transverse axis of the two doors in the closed state. The Y axis is oriented from left to right. The Y axis is parallel to the transverse axis of the motor vehicle once both doors are mounted on the motor vehicle. The Z axis designates the axis perpendicular to the longitudinal axis X and the transverse axis Y of the motor vehicle. When the motor vehicle rests on a horizontal ground, the Z axis is a vertical axis. However, in the description of the mounting method that follows, the two doors 1 0, 20 of the motor vehicle can be inclined relative to the orientation which is theirs when they are assembled on the motor vehicle. The Z axis no longer corresponds to the vertical axis. The marker is linked to all the two doors when they are in their closed configuration and in their adjusted relative position.

Throughout the document, the term "placement" refers to positioning and orientation. Positioning refers to a translation movement along one or more axes. The orientation refers to a rotational movement along one or more axes. The placement device makes it possible to place the two doors 10, 20 of a so-called initial investment at a so-called adjusted placement. The so-called initial placement may be any placement of the two doors. In so-called initial investment, each of the two doors rests on at least three points of support 32b, 35b of the placement device. In said initial placement, each of the two doors is placed so as to cooperate with at least one adjustment means 31, 32, 33, 34, 35, 36 of the placement device. The so-called adjusted placement is the relative placement of the two doors that is such that one can obtain:

- A game 3 calibrated and regular between the two doors along the transverse axis; and or

a zero offset or close to zero along the Z axis; and or

an offset, also called misalignment 5, zero or close to zero along the transverse axis Y; and or

- An inclination 6 between the plane of the outer face 18 of the front door 10 and the plane of the outer face 28 of the rear door 20 zero or close to zero;

by the only rotation of one and / or the other of the two doors relative to the axes of their respective hinges.

The game 3, the offset 4, the misalignment 5 and the inclination 6 are illustrated in Figures 2 and 3. The game 3 between the two doors along the transverse axis may be a game calibrated to a certain value. The game 3 can be defined for example according to design rules and / or to prevent or limit the injury of a finger wedged between the two doors. The game is regular when it has the same value, or substantially the same value over the entire height of the two doors. The clearance 3 and misalignment 5 between the two doors can be measured or considered at any height of the two doors along the Z axis or at an agreed height. The offset 4 can be measured or considered by comparison of the lower edges and / or the upper edges of the two doors and / or by comparison of the upper and / or lower edges of the windows of the two doors. The inclination 6 may correspond to the angle formed between the plane of the outer face 18 of the front door 10 and the plane of the outer face 28 of the rear door 20. The placement said adjusted can be obtained while the doors are open. Nevertheless, the notions of play 3, offset 4, misalignment 5 or inclination 6 make sense only when the two doors are in the closed position. By closed position is meant the relative position of the two doors as they would close a cabin of the motor vehicle once mounted on the body 2 of the motor vehicle 1. The closed position may correspond to at least an approximate alignment of the outer faces 18, 28 of the two doors 10, 20. The opening or closing of a door is done by activating a door opening / closing mechanism. for example by rotation about a pivot axis of the hinges according to the illustrated embodiment. As a variant, the offset 4, the misalignment 5 or the inclination 6 can be deliberately defined at non-zero values, for example by aesthetic choice. In such a case, the devices whose description will follow may simply be adapted to obtain a mounting of two adjacent doors as desired.

The placement device 30 may comprise a frame 40. The frame 40 may comprise a support plate 41 on which are fixed the at least two adjustment means 31, 32, 33, 34, 35, 36 and the at least three points of adjustment. support 32b, 35b. The frame 40 may also comprise stiffening elements 42 increasing the rigidity of the support plate 41. The support plate 41 may have a generally planar shape and extend in a plane substantially parallel to the longitudinal axis X and to the axis Z. A height H2 of the support plate 41 may be of the same order of magnitude as a height H1 of one of the two doors 10, 20. A length L2 of the support plate 41 may be of the same order of magnitude as the length L1 of the two doors 10, 20 placed side by side. The support plate 41 can be oriented horizontally in a workshop or alternatively in any other inclination.

The two doors are placed according to their initial placement on the at least three points of support 32b, 35b, two of which are particularly visible in FIG. 5. The inner faces 17 of the two doors are at least approximately facing the support plate 41. According to the embodiment presented, the placement device 30 comprises:

a first adjustment means 31 for the position of the front door 10 along the longitudinal axis X,

a second adjustment means 32 for the position of the front door 10 along the transverse axis Y,

a third adjustment means 33 for the position of the front door along the axis Z.

In addition, the first adjustment means 31 and the third adjustment means 33 make it possible to define the orientation of the front door 10 around the transverse axis Y. The second adjustment means 32 makes it possible to define the orientation of the door before 10 around the longitudinal axis X and the axis Z.

Similarly, the placement device 30 comprises adjustment means 34, 35, 36 of the position and orientation of the rear door 20 along the longitudinal axis X, the transverse axis Y and the Z axis. adjusting means 31, 32, 33, 34, 35, 36 may comprise a jack 31a, 33a, 34a, 36a and a positioning stop 31b, 33b, 34b, 36b. Alternatively, a placement device 30 could comprise position or orientation adjustment means along only one axis or adjustment means along only two axes.

As illustrated in FIG. 1, the adjustment means 31 for the position of the front door 10 along the longitudinal axis X comprises on the one hand a jack 31 is oriented along the longitudinal axis X and bears against the front edge 12 of the front door 10. On the other hand, the adjustment means 31 comprises a positioning stop 31b disposed towards the rear edge 1 1 of the door before 10. The adjustment means 34 of the position the rear door 20 along the longitudinal axis X comprises on the one hand a cylinder 34a oriented along the longitudinal axis X and bearing against the rear edge 21 of the rear door 20. On the other hand, the adjustment means 34 comprises a positioning stop 34b disposed towards the front edge 22 of the rear door 20. In a variant, the placement of the jacks 31a, 34a and the placement stops 31b, 34b could be inverted, that is to say the cylinder 31a could be supported on the rear edge 1 1 and the corresponding stop to the front edge 12 of the front door 10. Similarly, the cylinder 34a could be supported on the front edge 22 and the corresponding stop towards the rear edge 21 of the rear door 20. Toutf However, the placement of the placement stops between the two doors 10, 20 as shown in Figure 1 advantageously allows adjustment of the game 3 and parallelism between the front edge 22 of the rear door 20 and the rear edge 1 1 of the front door 10 regardless of manufacturing tolerances of the two doors 10, 20, in particular regardless of the length dispersion of the two doors along the longitudinal axis X.

The adjustment means 33 for the position of the front door 10 along the axis Z comprises on the one hand a jack 33a oriented along the Z axis and resting against an upper edge 13 of the front door 10 or, as illustrated in FIG. 1 against the lower edge 1 6 of the window 15 of the front door 10. On the other hand, the adjustment means 33 comprises a positioning stop 33b disposed towards the lower edge 14 of the front door 10. From analogously, the adjustment means 36 along the Z axis of the rear door 20 comprises a jack 36a and a positioning stop 36b.

The positioning stops 31b, 33b, 34b, 36b of the different adjustment means may consist of two supports 31c, 31d extending in a direction perpendicular to the axis of adjustment, that is to say perpendicular to the orientation of the cylinder. Thus, the positioning stops of the adjusting means 31, 34 each comprise two supports 31c, 31d and 34c respectively, 34d oriented along the transverse axis Y particularly visible in FIG. An axis perpendicular to the transverse axis Y and passing through the two supports 31c, 31d may be parallel to an axis perpendicular to the transverse axis Y and passing through the two supports 34c, 34d. Thus, when the two doors 10, 20 are in abutment against the supports 31c, 31d, 34c, 34d, the front edge 22 of the rear door 20 is parallel to the rear edge 1 1 of the front door 10 and therefore the game 3 is regular over the entire height of the two doors 10, 20. The positioning stops of the adjusting means 33, 36 each comprise two supports 33c, 33d and respectively 36c, 36d oriented along the transverse axis Y. An axis perpendicular to the transverse axis Y and passing through the two supports 33c, 33d can be confused with an axis perpendicular to the transverse axis Y and passing through the two supports 36c, 36d. Thus when the two doors are supported each against these two supports, the lower edges of the two doors 10, 20 are aligned and parallel. The positioning stops of the different adjustment means are intended to come into contact with their respective door by actuating their respective cylinder. For example, when the cylinder 31 has pushed the door 10 against the stop 31b, the door 10 is then supported against the two supports 31c, 31d. The positioning stops of the various adjustment means are locked in position on the support plate 41. When the front door 10 bears against the supports 31c, 31d, 34c, 34d, the position along the longitudinal axis X, the position along the axis Z and also the orientation about the transverse axis Y of the front door 10 are defined and correspond to the so-called fitted placement of the front door 10. Similarly, when the rear door 20 bears against the supports 34c, 34d, 36c, 36d, the position along the longitudinal axis X, the position along the Z axis and also the orientation around the transverse axis Y of the rear door 20 are defined and correspond to the so-called fitted placement of the rear door 20.

The adjustment means 32 of the position the front door 10 along the transverse axis Y may comprise at least three bearing points 32b on which the front door 10 is intended to rest. The at least three bearing points 32b can be locked on the support plate 41 or can be movable along the transverse axis Y, for example by means of a jack oriented along the transverse axis Y interposed between the support plate 41 and the at least three points of support 32b. The front door 10 is supported on the at least three bearing points 32b by its inner face 17. In addition, the adjustment means 32 may comprise a clamping means 32a pressing on the outer face 18 of the front door 10 along the transverse axis Y and ensuring that the front door 10 rests on the at least three points of support 32b. The clamping means 32a may comprise a jack exerting a thrust against the outer face 18 along the transverse axis Y and directed towards the support plate 41. Alternatively, the clamping means 32a may comprise an element adapted to perform a rotary movement, for example a rotary movement about an axis parallel to the longitudinal axis X or parallel to the axis Z. The element bears on the outer face 18 of the door and produces the same force on the door before a cylinder oriented along the transverse axis Y. Similarly, the adjustment means 35 along the transverse axis Y of the rear door 20 comprises a clamping means 35a and at least three support points 35b that can be locked in position on the support plate 41. The clamping means 32a, 35a is movable between a first position and a second position. The first position is intended to allow input or removal of the front door 10 and / or the rear door 20 on the placement device 30. The second position is intended to ensure that the door is in support against the different points of support which make it possible to define its position unequivocally with respect to the support plate 41. When the front door 10 is in abutment against the at least three bearing points 32b, the position along the transverse axis Y, the orientation about the longitudinal axis X and also the orientation around the axis Z of the front door 10 are defined and correspond to the so-called fitted placement of the front door 10. Similarly, when the rear door 20 is in abutment against the less three support points 35b, the position along the transverse axis Y, the orientation about the longitudinal axis X and also the orientation around the Z axis of the rear door 20 are defined and correspond to the so-called fitting placement of the rear door 20.

The at least three support points 32b can be defined or controlled so that the front door 10 forms an opening angle of about 45 ° with the support plate 41. The opening angle 19 is formed at the hinge of the front door 10. The at least three bearing points 35b can be defined or controlled so that the rear door 20 forms an opening angle 29 of about 10 ° with the support plate 41. The opening angle 29 is formed at the hinge of the rear door 20. Thus, the relative placement of the two doors placed on the placement device corresponds at least substantially to a possible relative placement of the two doors when mounted on the motor vehicle. In particular, the front door 10 can be opened at 45 ° with respect to the longitudinal axis of the motor vehicle. The rear door 20 can be opened at 10 ° with respect to the longitudinal axis of the motor vehicle. Alternatively, the doors can be kept open with an opening angle 19, 29 different. The opening angle of each door 10, 20 is defined to allow the attachment of the hinges 101, 201 to the vehicle body Alternatively, the cylinders of the various adjustment means and / or the placement stops may be supported on any door element comprising a bearing surface or a support section substantially perpendicular to the orientation of the cylinder. According to another variant, the doors can be:

- placed in support and / or maintained in manual support against the stops of placement, and / or

- placed in support and / or maintained in support under their own weight against the stops of placement.

The placement device 30 may also comprise a control device (not shown) connected to at least one jack or clamping means, preferably to all the jacks and clamping means of the positioning device 30.

Finally, the placement device 30 may comprise at least one first element 43, or even at least two first elements 43, of a first docking device 63. The at least two first elements may be positioned on two sides of the plate support 41. The at least one first element 43 is intended to cooperate with at least one second element 59 of the first docking device 63. The at least one second element 59 is integral with a gripping device 50. The first device docking 63 makes it possible to place the gripping device 50 with respect to the positioning device 30. The at least one first element 43 may comprise a bearing surface 44 extending approximately parallel to the plane of the support plate 41. The at least one first element 43 may also comprise a relief oriented at least partially along the longitudinal axis X and / or the axis Z. The second element 59 comprises a shape complementary to the first element 43. Supporting the second element 43 element 59 against the first element 43 according to their complementary reliefs makes it possible to position and orient accurately and single the gripping device 50 relative to the placement device 30. An embodiment of the first and second element may be a shape parallelepiped or a cylindrical shape on one of the two elements cooperating with a recess of complementary shape on the other element.

The various jacks and / or stops and / or clamping means and / or first elements of the first docking means 63 can be fixed firmly to the support plate 41 by means of a fixing foot 45. fixing foot 45 comprises a base 46 fixed, for example screwed, to the support plate 41 and an axis, for example a profile 47, making the connection between the base 46 and the cylinder 31a, 33a, 34a, 36a or the stop 31b, 33b, 34b, 36b or the first element 43 of the first docking device or the clamping means 32a, 35a. The profile 47 may extend perpendicularly to the plane of the support plate 41. The support plate 41, the fixing feet 45, the positioning stops 31b, 33b, 34b, 36b, the at least three bearing points 32b, 35b are preferably made of metal. Alternatively, they can be made of any material whose rigidity is sufficient not to deform significantly during use, especially when the two doors against the abutment stops and / or at least three points support.

According to an alternative embodiment, the position of the fixing feet and / or the support points can be reconfigured on the support plate 41 so as to use the placement device 30 with different door shapes corresponding to different types of motor vehicles. .

Figures 4, 5 and 6 illustrate an embodiment of the gripping device 50. The gripping device 50 is intended to grip the two doors 10, 20 simultaneously or almost simultaneously and move them together to the body 2 of the motor vehicle 1 with a view to assembling the two doors 10, 20 on the body 2. The device for gripping comprises a rigid frame 51 equipped with telescopic suction cups 52 or a telescopic group of suction cups, a handling arm 53, a connection element 54 to a building and a control device 60.

The rigid frame 51 extends in the form of a plane. A height H3 and a length L3 of the rigid frame approximates the height H2 and the width L2 of the support plate of the placing device 30. The frame may be formed by bars 58 fixed together, for example welded or screwed together. The telescopic suction cups 52 or the telescopic suction pad group can be attached to the rigid frame 51. The telescopic suction cups 52 or the telescopic group of suction cups are intended to grip the two doors by the outer face 18, 28 of each door. The telescopic suction cups 52 or the telescopic group of suction cups can be movable relative to the rigid frame 51 along an axis perpendicular or substantially perpendicular to the plane formed by the outer face of the door that they are intended to grip. For this purpose, the telescopic suction cups 52 or the telescopic group of suction cups may comprise a slide connection, and in particular a jack. In a first configuration, the slide connection can be free, the telescopic suction cups 52 or the telescopic suction pad group can therefore move perpendicularly or substantially perpendicular to the plane formed by the outer face 18, 28 of the door 10, 20 they are intended to seize. In a second configuration, the slide link can be blocked. The telescopic suction cups 52 or the telescopic group of suction cups are then locked in position relative to the rigid frame 51.

The control device can operate autonomously, that is to say as a control automaton, or in a semi-autonomous manner, that is to say in a manner assisted by at least one operator 62. For example, the device The driver may comprise a console 61 serving as an interface between the operator 62 and the gripping device 50. FIGS. 7, 8 and 9 illustrate a hinge mounting device 70 intended to mount at least one hinge 101 , 201 on a door 10, 20. According to the embodiment shown, two hinges 101, are mounted near the front edge 12 of the front door 10. A similar device can be used for mounting the hinges 201 of the rear door 20. The hinge mounting device 70 comprises a support plate 71, placement elements 72 for placing the door along the longitudinal axis X, the transverse axis Y and the vertical axis Z, at least one suction cup 73 , two ve Ntouses 73 according to the illustrated embodiment, intended to block the placement of the door on the hinge mounting device 70. The support plate 71 extends in a plane parallel to the longitudinal axis X and the Z axis. The support plate 71 may be arranged horizontally or substantially horizontally. Finally, the hinge mounting device 70 comprises two guide rails 74 and a mobile device 75 in sliding connection on the guide rails 74. The guide rails are aligned along an axis of the support plate 71, the longitudinal axis according to the embodiment presented. The mobile device 75 serves to place the hinges on the doors. The placement elements 72, the at least one suction cup 73, and the two guide rails 74 are locked on the support plate 71. The placement elements 72 may comprise, for example, flanges 720 oriented along the longitudinal axis X or the axis Z. The flanges 720 are intended to be positioned on the contour and / or at angles of the door. For example, a first flange 720a is intended to be positioned vis-à-vis the upper edge 13 of the front door 10. A second flange 720b is intended to be positioned vis-à-vis the rear edge 1 1 of the front door 10. A third flange 720c is intended to be positioned vis-à-vis a lower rear corner of the front door 10. A fourth flange 720d is intended to be positioned vis-à-vis a corner lower front of the front door 10. A fifth edge 720e is intended to be positioned vis-à-vis a front edge 12 of the front door 10. The placement elements 72 and the ledges 720 are arranged to create a stable placement for the door 10 placed thereon. The placement members 72 may be removable to reuse the hinge fixture 70 with different door shapes, including the back door 20 or other front door shapes corresponding to other motor vehicles. The hinge mounting device 70 may also include a fastener tool 80 of the at least one hinge on the door. The attachment tool may be for example a screwing means such as a screwdriver or an electric screwdriver. The attachment tool may be connected by a cord or flexible cable to the support plate 71. Thus the attachment tool 80 is always within reach of an operator wishing to fix the at least one hinge on the door.

The mobile device 75 slides on the guide rails 74 between a first position and a second position. In first position, the mobile device 75 bears against a first stop 76a. In second position, the mobile device bears against a second stop 76b. The first position is a preparation position intended to place two hinges January 01 to be mounted on the mobile device 75. The second position is a position for screwing the two hinges January 01 on the door 1 0. The mobile device comprises two insertion plates 77 on which the two hinges 1 01 can be mounted. The two insertion plates 77 may have a substantially planar shape. The two insertion plates 77 may be parallel to the plane defined by the support plate 71 and / or be disposed horizontally. A hinge January 01 is composed of a hinge 1 02 intended to be fixed on the body of the motor vehicle and a wing 1 03 to be fixed on the door. The hinge 102 and the wing 1 03 are pivotally connected about an axis. The hinge and the wing each have two holes 1 04, 1 05 of fixing for the passage of fixing screws. The two insertion plates may each comprise two pins 78 intended to cooperate with the two attachment holes of the hinge 102 of each hinge 101. The two insertion plates may have a shape matching the shape of the hinge 1 02. Thus the hinges 101 are precisely placed on the mobile device 75. Finally, the mobile device 75 may comprise a handle 79 for slidingly moving on the hinges. guide rails 74 from the first position to the second position and vice versa. When the mobile device 75 bears against the abutment 76b, the hinges are precisely placed relative to the contour of the door 10 along the three axes X, Y and Z.

In addition, the insertion plates 77 can be connected to one or more springs oriented along the transverse axis Y. Thus, after the hinges are fixed on the door, the insertion plates can be pushed towards the support 71 by compression of the spring or springs. In this way, the two pins 78 of each insertion plate 77 can be disengaged from the fixing holes of the hinge 1 02. The mobile device 75 can then be moved against the first stop 76a. One embodiment of a mounting method according to the invention is described below with reference to FIGS. 10, 11 and 12.

Advantageously, the mounting method comprises several steps, among which:

- A hinge fixing step E1 comprising fastening, including screwing, at least one hinge 101, 201 on at least one door 10, 20;

an investment step E2 comprising the definition of a relative placement of the two doors 10, independently of a real geometry of a box 2 of the motor vehicle 1, that is to say that the doors one relative to the other at a distance from the body on which they are intended to be mounted and the relative placement of the two doors is not disturbed by the manufacturing dispersions of the body;

- A gripping step E3 comprising gripping the two doors 10, 20 by the gripping device 50, in particular a gripping step E3 retaining the relative placement of the two doors 10, 20 defined during the placement step E2;

a displacement step E4 comprising moving the gripping device 50 provided with the two doors 10, 20 from a first location to a second location while maintaining their relative placement defined during the placement step E2. The first location is defined by the coincidence of a first element 43 of a first docking device 63 with a second element 59 of the first docking device 63, the first element 43 of the first docking device 63 being integral with the placement device 30 and the second element 59 of the first docking device being integral with the gripping device 50. The second location is defined by the actual geometry of the body 2 of the motor vehicle 1, in particular by the coincidence of a first element 65 of a second docking device 64 with a second element 66 of the second docking device 64, the first element of the second docking device being integral with the gripping device 50 and the second element of the second docking device being secured to the cash register 2.

- An attachment step E5 comprising fixing at least one door 10, 20 on the body 2 of the motor vehicle 1, preferably the fixing of the two doors 10, 20 on the body of the motor vehicle 1.

The hinge fixing step E1 may comprise a first substep E1 1 comprising placing the at least one door 10, 20 on the hinge mounting device 70. The door is placed in a stable position resting on the various placement elements 72. The door can be placed with its outer face opposite the support plate 71. The edges of the door are positioned against the flanges 720 of the placement elements. This placement is blocked by the at least one suction pad resting on the outer face 18 of the door. Therefore, the door is locked relative to the support plate 71. This placement is defined by the outside contour of the door

The hinge fixing step E1 may comprise a second sub-step E12 comprising placing the at least one hinge 101, 201 on the hinge mounting device 70. The at least one hinge is placed on a hinge plate. 77. The fixing holes of the hinge 102 are made to coincide with the pins 78 of the insertion plate 77. The hinge thus placed is locked in position along the longitudinal axis X and the axis Z. When the hinge plate 102 insertion is disposed horizontally or substantially horizontally, the hinge rests by gravity on the insertion plate which defines the position of the hinge 102 relative to the support plate 71 along the transverse axis Y. The placement of the hinge at least one hinge on an insertion plate is made while the moving device is in the first position.

The hinge fixing step E1 may comprise a third substep E1 3 for moving the mobile device from the first position to the second position. This displacement can be achieved for example by an operator grasping the handle 79 and thus moving the mobile device against the second stop 76b. The hinge January 01, 201 is thus placed along the three axes X, Y and Z relative to the edges of the door resting on the placement elements

The hinge fixing step E1 may comprise a fourth sub-step E14 for screwing the wing 1 03 of the hinge January 01 to the door 1 0. Advantageously, the fixing holes 105 of the wing 1 03 are sufficiently large to allow screwing of the hinge on the door taking into account the manufacturing dispersions.

As illustrated in FIG. 10, the substeps of the hinge fixing step E1 are preferably carried out in this order:

the substep E1 1 precedes the substep E12,

the substep E12 precedes the substep E13,

substep E13 precedes substep E14.

Thus at the end of the hinge fixing step E1, the two doors 10, 20 are each provided with at least one hinge January 01, 201, two hinges according to the embodiment shown. The hinges January 01, 201 are placed and locked in position on the doors by reference to the outer contours of each door. The placement step E2 may comprise a first substep E21 comprising an implementation of the two doors on the placement device 30 according to a so-called initial placement. During this sub-step, the front door 10 and the rear door 20 are placed in abutment each on the at least three points of support 32b, 35b. The front edge of the front door is at least substantially placed vis-à-vis the cylinder 31a. The lower edge 1 6 of the window 15 is, at least substantially, placed vis-à-vis the cylinder 33a oriented along the axis Z. Similarly the rear door 20 is placed, at least substantially, vis-à-vis screw cylinders 34a and 36a. Then the clamping means 32a, 35a bear against the outer face of the two doors so as to press against their at least three bearing points 32b, 35b respectively.

The placement step E2 may comprise a second substep E22 comprising an adjustment of the orientation of at least one door 10, 20. The opening angle 19 of the front door 10 with the longitudinal axis X may to be at least approximately equal to 45 °. The opening angle 29 of the rear door 20 with the longitudinal axis X may be at least approximately equal to 10 °. According to an alternative embodiment, the adjustment can be obtained by actuating the cylinders oriented along the transverse axis Y interposed between the support plate 41 and the at least three bearing points 32b, 35b. According to another variant, the at least three bearing points 32b, 35b are not movable along the transverse axis Y and the opening angle 19, 29 of each door is defined as of the substep E21 in which the two doors 10, 20 are each supported on the at least three bearing points 32b, 35b. The placement step E2 may comprise a third substep E23 comprising an adjustment of the position of at least one door 10, 20 along the longitudinal axis X and / or along a transverse axis Y and / or along the axis Z and / or an adjustment of the orientation of the at least one door 10, 20 about the longitudinal axis X and / or about a transverse axis Y and / or about the Z axis. step may comprise the support of at least one door 10, 20 against the placement stops 31b, 33b, 34b, 36b. During this sub-step, the cylinders 31a, 33a, 34a and 36a are operated. The cylinders exert a thrust along the transverse axis X or the Z axis of each door. The doors move by sliding on their at least three bearing points 32b, 35b until coming into contact against the stops 31b, 33b, 34b, 36b. At the end of this sub-step, the lower edge 14 of the front door 10 bears against the stop 33b, the rear edge 11 of the front door 10 bears against the abutment 31b, the lower edge of the rear door 20 bears against the abutment 36b, the front edge 22 of the rear door 20 bears against the abutment 34b.

As illustrated in FIG. 11, the substeps of the placement step E2 are preferably carried out in this order:

the substep E21 precedes the substep E22, and / or

substep E22 precedes substep E23.

However, the substep E22 could also be performed after the substep E23.

At the end of the placement step E2, the two doors 10, 20 are in so-called adjusted placement. The placement of the two doors is done independently of the actual geometry of the box on which they are intended to be mounted.

Actuation of the jacks and / or clamping means of the placement device can be ordered by the control device of the placement device. Actuation of the jacks and / or the clamping means can be performed simultaneously or sequentially, that is to say one after the other.

During the gripping step E3, the rigid frame 51 of the placing device 30 is approached. The rigid frame 51 is placed precisely with respect to the positioning device 30 by means of the first docking device 63. The placement is obtained when the first element of the first docking device 63 coincides with the second element of the first docking device 63. Once placed relative to the placement device 30, the rigid frame is locked in position relative to the placement device 30. The telescopic suction cups 52 or the telescopic group of suction cups are set in motion until come against the outer face of each door. The suction cups or the telescopic group of suction cups are then actuated in a manner to create a cohesive force with the doors. The suction cups or the telescopic group of suction cups are then locked in position relative to the two doors. The slide connection of each suction cup or telescopic group of suction cups can then be blocked. Therefore the two doors are locked in position relative to the rigid frame 51. The clamping means 32a, 35a of the placement device can be actuated so as to release the two doors. At the end of the gripping step E3, the two doors have retained their relative placement defined during the placement step E2.

During the moving step E4, the handling arm 53 is actuated so as to move the rigid frame 51 of the placement device to the body of the motor vehicle. The movement can be completely automated or assisted by an operator controlling the movements of the manipulator arm. The rigid chassis is then placed precisely relative to the body of the motor vehicle through the second docking device. The hinge leaf fixing holes of the two doors then coincide with the fastening holes provided in the body of the motor vehicle. Advantageously, the fixing holes 104 of the hinge 102 are sufficiently large to allow screwing of the hinge on the body taking into account the manufacturing dispersions. During the displacement step E4, the relative placement of the two doors defined during the placement step E2 is retained. Alternatively, the relative placement of the two doors could be changed according to a predetermined amount, for example the clearance between the two doors could be increased or reduced between the placement step E2 and the step of fixing the two doors E5 on the body of the motor vehicle.

During the fixing step E5, the hinge 1 03 of the two hinges 1 01, 201 of each door 1 0, 20 is fixed to the body 2 of the motor vehicle. Fixing is carried out by screwing through the attachment holes 105 of the hinges 103 of each hinge. Access to the fixing holes 105 is facilitated by the opening angle 19, 29 for opening the two doors. Once the screwing is completed, the telescopic suction cups 52 or the telescopic suction cup group of the gripping device can be detached from the two doors 1 0, 20. The two doors are thus separated from the gripping device 50.

As illustrated in FIG. 10, the steps of the mounting method are preferably carried out in this order:

step E1 precedes step E2,

step E2 precedes step E3,

step E3 precedes step E4,

step E4 precedes step E5.

Thanks to the invention, two contiguous doors of a motor vehicle are assembled on the body of the motor vehicle. The two doors are positioned and oriented independently of the actual geometry of the body of the motor vehicle. Thus, the adjustment of the game 3, the offset 4, the misalignment 5 and the inclination 6 between the two doors is not disturbed by the dispersions and manufacturing tolerances of the body. The placement and orientation of the two doors obtained by this method are elegant and preserve the conformity of the opening and closing mechanism of each door. In addition, the method allows quick assembly of the two doors on the vehicle body. In addition, the placement device, the gripping device and the hinge mounting device embodying the mounting method constitute a set of modular mounting means that can be used for different vehicle geometries.
