    Printed: 29-05-2012 E014.1 [10 ^) ^ 50204 P12582 Three-way adjustable mounting arrangement for one component,
    IN PARTICULAR A HEADLAMP OF A MOTOR VEHICLE
    The invention relates to a fastening arrangement for connecting a component, in particular a headlight, with a carrier device, wherein the component has an annular receiving area with a receiving opening, in which a fastening part (which may be a screw, for example) of the support means by means of a threaded part in an adjustable position is detectable.
    Moreover, the invention relates to a method for fixing a fastening arrangement on a receiving region of a component with respect to a carrier device with which the component is to be connected via the fastening arrangement.
    In the automotive industry increasingly tighter tolerances in the connection of components are required. When mounting a piggery (or other component) in the associated housing often occurs the problem that due to production-related tolerance chains, the position of the mounting holes and / or contact surfaces on the headlight housing can not be set with the required tight tolerances. The front end supports can be manufactured today with a very low tolerance, which may for example be in the range of the order of 0.1 mm. In a headlamp or luminaire housing, which is mounted on a front end support, but often occur by the injection molding process greater tolerances, for example, by warping during cooling of the plastic part, which can lead to greater inaccuracies. The provided on the plastic part mounting holes, which are typically provided on integrally molded tabs on the housing, then no longer match exactly with the mounting holes on the carrier. As a result, required gap dimensions on the end product (vehicle) can not be achieved. Rather, the position varies within a certain range, wherein the deviation from the target position in the final state of the mounted headlight can lead to misalignments.
    Previous approaches to correct for such a deviation have been e.g. the (e.g., machining) post-processing of the receiving elements of the headlight housing.
    Printed: 29 ^ 05-2012 E014.1 ί102012 / 50204
    Another approach is to provide for a certain positionability of the fastener used in the receiving opening to compensate for its position relative to the desired position can. A well-known example is the design of the receiving opening as a slot, which results in an adjustability along the direction of the slot, perpendicular to the axis of the plugged through screw results. However, this is also accompanied by a reduced stability of the attachment in this direction.
    Also known is the solution of a Spreizdübels to set a fastener such as a screw in a (large) receiving opening. Special developments of this concept are described in DE 10 001 426 A1 and DE 10 2009 021849 A1. DE 199 49 467 A1 describes a fastening arrangement for fixing a functional part to a component with regard to two degrees of freedom by using an inclined plane with a ribbed design. By multiple use of the mounting arrangement, the number of degrees of freedom can be increased accordingly.
    The known solutions do not allow adjustability of the positioning in the three directions of the room or only with great effort. This results in a major disadvantage that after a renewed expansion of the headlamp and the exact position of the mounting holes is lost the headlamp must therefore be re-installed at replacement.
    It is therefore an object of the invention to overcome the disadvantages of the known Befestigungsanord- voltages, and to provide an arrangement that allows compensation in all three spatial directions with few components and reliably with high accuracy of the set positioning. This should be possible in particular with regard to the application in the attachment of headlamps and associated components in a motor vehicle, with a fast and less error-prone mounting is desired.
    This object is achieved on the basis of a fastening arrangement of the type mentioned above by means of the following components of the arrangement: a connecting element which has an axis-oriented threaded part, the thread of which is designed to mate with the fastening part, and which is formed on the receiving opening by means of a clamping connection which fixes a position adjustable during assembly of the connecting element with respect to two directions transverse to the axis can be mounted, wherein in the assembled state, the axis passes through the receiving opening, and - a compensation element, which in a third direction defines adjustable stop for the carrier device, to which the fastening arrangement is connectable by means of the held by the threaded portion of the connecting element fastening part.
    This solution provides adjustability for a position adjustable in three directions with respect to the receiving opening by a small number of components of the mounting arrangement. It thus enables a 3-axis tolerance compensation (i.e., setting the position with respect to three degrees of freedom) for the attachment of a component to a fastening part, for example fixing a headlamp to a front end support of a motor vehicle. The invention allows, in particular, that this fastening arrangement can be prefixed at the installation site and retains the embossed position until the final assembly of the component (in particular headlamp). In this way, an additional adjustment in the final assembly of the component on the associated carrier (especially headlight frame) is unnecessary. In addition, the invention allows the tolerance compensation remains in its correct position even with later expansion of the component / headlamp repeated removal and installation of the component / headlight thus the exact position and the associated gap dimensions are maintained, and the headlight must not be re-established ,
    In the context of this disclosure, under " part " primarily a headlight or a headlight component understood, which is installed on a support means, in particular a front end support, a motor vehicle in a predetermined mounting position. In addition, in a generalized manner, the component may be a component of a device, wherein the component is to be installed in the device in a pre-assembled mounting position; However, the above application for headlights (components) is in the foreground.
    With "Fastener " is a part of the support which serves to secure the component (such as a spigot, which may possibly have a screw thread) or a fastener (such as a screw); or 29005-2012 E014.1 102012/50204 - 4 which is firmly connected to a carrier in a subsequent operation for fastening the component, referred to.
    For the purposes of this disclosure, the terms " top " and "below" are used, these relate only to the orientation of the components within the mounting assembly, regardless of an actual orientation of the mounting assembly and the component (pig-thrower) in its mounting position.
    In the case that the fastening part is a screw, the threaded part of the connecting element may favorably be an internal thread for receiving the at least partially formed as a screw fastening part.
    According to a first advantageous development of the invention, the clamping connection of the connecting element can be achieved in that it has a number of feet which are arranged around the threaded part. The feet can be guided in this case in the receiving area by associated opening areas and be plastically deformable to form the clamp connection. For example, the connecting element may be a socket nut, which on the one hand contains the threaded part mentioned, on the other hand is equipped with additional holding means such as the already mentioned feet for positioning with respect to the adjustable terminals.
    In a further development of the invention with respect to the compensating element, this has an annular configuration, with an axis which extends in the mounted state to the axis of the connecting element substantially parallel, and with a stop surface forming the end face. As a result, the compensation element fulfills the function of adjusting the height of the end face (third coordinate) in a particularly simple yet convenient manner.
    In this case, the compensating element can be plugged onto the receiving area relative to the connecting element, wherein the height of the end face is adjustable over the receiving area In an expedient development of this variant, which enables easy and reliable emstelle the height by turning the compensating element, the compensating element on his The receiving area facing side have a helical support surface which is designed so that it cooperates with a helical counter surface of the receiving area. Alternatively, another development can provide that the compensation element facing the receiving area,
    Printed: PI2582 29-05-2012 E014.1 10 2012/50204 -5- has force-adjustable along the axis deformable feet, with which the compensation element can be supported on the receiving area. This allows a direct adjustment of the required height of the end face as a stop, without that on the compensating element a rotational movement (which requires a pivoting of the tool and is cumbersome and time-consuming) is required.
    A further embodiment of the invention, which can be combined in particular with the aforementioned refinements, provides that the compensation element has a collar facing the receiving area on an inner edge of the annular shape, and that the screw thread (ie the threaded part) of the connecting element in the assembled state through the receiving opening protruding into the collar Here, it may be beneficial to form a guide in the axial direction in cooperation with the latter. This allows a more stable alignment of the attachment part in the assembly.
    In contrast, another development of the invention provides that the connecting element has an end face serving as a stop and is adjustable in its position along the axis using the compensating element. For example, the connecting element may be formed as an adjusting nut or screw, which is positioned within the receiving opening.
    In an advantageous embodiment of this development, which requires no special design of the receiving area and allows attachment in any spatial position, the compensating element may be formed by two in the mounted state on opposite sides of the receiving area arranged mothers that have mutually opposite Windungsrichtungen and on each associated external thread of the connecting element are attachable to form a laterally adjustable clamping connection. Here, an embodiment of this variant may include a spring structure which is arranged between the Muttem in the assembled state and is compressible in the direction parallel to the axis, wherein the spring structure engages in structures on the facing surfaces of the Muttem, whereby the rotation of the Muttem are coupled about the axis can.
    Another advantageous embodiment of the development is characterized in that the compensation element can be attached by a laterally attachable to the receiving area
    Printed: 29-05-2012 E014.1; 10 2012/50204
    Clamp (socket nut) is formed, which has a hollow guide for the connecting element. Here, the hollow guide may be at least partially executed as an internal thread, which corresponds to an external thread of the connecting element. The connecting element may also have a section with a second external thread, to which a lock nut for securing at one end of the hollow guide can be attached. This design requires a small number of components and avoids permanent deformation of parts of the components, e.g. Bending feet or dgL, for making the attachment.
    Based on a mounting arrangement of the type according to the invention already explained, the invention also provides a method for fixing a fastening arrangement to a receiving region of a component at a desired position with respect to a carrier device with which the component is to be connected via the fastening arrangement Method, the following steps are carried out: arranging the components of the fastening arrangement (in particular the connecting element and the compensation element of the fastening arrangement) on the receiving area, whereby a provisional position of the connecting element and the stop (which is determined by the compensating element) of the fastening arrangement is taken; - matching the preliminary position with a target position - the target position has been previously determined (and still before or preferably after the step of arranging the component of the mounting arrangement) on the component with respect to the carrier device by means of a 3D measurement of the component; - Aligning and fixing the connecting element with respect to two directions transverse to the axis of the connecting element, according to the difference between the provisional and target position with respect to the two directions; - Aligning and fixing the stopper by means of the compensating element with respect to a third direction, namely along the axis of the connecting element, according to the difference between the provisional and target position with respect to the third direction.
    The desired position determines the position of the fastening part or the connection between the component (headlight) and the carrier device that is created by means of this.
    It is particularly advantageous that the orientation of the mounting assembly with respect to the desired position (with respect to the three directions mentioned) after connecting the -7-Printed: P12582 29-05-2012 102012/50204
    Component with the support device is maintained as well as in subsequent subsequent loosening and re-establishing the connection.

    A mounting arrangement 101 for a headlight according to the first embodiment of the invention is shown in FIGS. 1 to 6.
    Fig. 1 illustrates in a perspective view in partial section the attachment of a headlamp (of which only part of the associated housing 2 is shown here) on a support 3 of a vehicle body by means of a fastening arrangement 101 according to the embodiment. (Only a small part of the carrier is shown in the drawing.) As can be seen, the headlight housing 2 has a tab serving as a receiving element 102, in which a receiving area 103 is formed, to which the fastening arrangement 101 is attached. A fastening part, in this case a fastening screw 4, holds the fastening arrangement 101 prefixed to the housing 2 to the support 3 and thus to the vehicle body.
    Due to manufacturing deviations, the receiving element 102 can be formed only with a certain position inaccuracy on the headlight and thus may be subject to a misalignment relative to the actual headlight (more precisely, to the visible from outside the body part of the headlight); this misalignment is compensated by the fixing element 101 prefixed to the receiving element. The fastening arrangement 101 is attached in the correct compensating position before the headlight is mounted on the carrier 3 (prefixing). This allows P12582 to meet the required tolerance for a uniform gap (of, for example, 2 mm circumferential).
    2a and 2b show the pre-fixed to the headlight housing 2 mounting assembly 101 in relation to FIG. 1 enlarged perspective views. Hereinafter, the area of the receiving area 103 visible in FIG. 2a will be referred to as "front side". (the opposite side as "back side"). On the housing 2 of the headlamp is a receiving area 103 for receiving a fixing lugs 4, namely a fastening screw provided for its attachment. For this purpose, the receiving region 103 in a receiving element 102 is ausgebüdet and designed in a manner corresponding to the attachment assembly 101.
    In Fig. 3, the receiving element 102 is shown without the components of the fastening arrangement in a perspective view. The receiving element 102 has, in the middle of the receiving area 103, an opening 104 through which the fastening screw is to be guided during the final assembly. In addition, the receiving region 103 is designed specifically in a manner corresponding to the fastening arrangement 101.
    The opening 104 is made larger than corresponds to the cross section of the screw 4, so that the position of the screw can be adjusted depending on the malposition to be corrected within the opening. The receiving region 103 has the basic shape of an annular disc, the additional holding structures 105, 106, 107, 108, 109 for attaching the components of the fastening assembly 101, which are explained below. The receiving element 102 consists for example of plastic, as well as the headlight housing, and is preferably formed integrally with the housing (2). The shape of the receiving element 102 and in particular of the structures 105, 106, 107, 108, 109 formed thereon is advantageously designed such that that an injection molding of the element can be done with as few moldings as possible (demolding structures).
    Fig. 4 shows a plug nut 110, which serves as a connecting element according to the invention. The plug nut 110 has a threaded portion 112 located in the center of a base plate 111 that defines an axis c. In addition, the base plate 111 carries a number of tongues or feet 113 disposed about the threaded portion 112. The number of feet 113 is preferably three, but may be another convenient number of
    Printed: 29-05-2012 £ 014.1 102012/50204 P12582 -11-
    113 can be selected from three upwards depending on the application. The feet 113 are oriented parallel to the axis c at the beginning of assembly of the plug nut 110 to allow the assembly process (insertion of the feet 113 through the openings 106), as will be explained below, and are plastically deformable to provide the clamp connection according to the invention , which allows a Einsteilbarkeit the position of the plug nut 110 with respect to two directions transverse to the axis c. The threaded portion 112 is executed in the illustrated embodiment as an internal thread, which is arranged opposite the feet 113.
    Referring to Figs. 5a and 5b, the plug nut 110 is mounted on the receiving portion 103 by being mounted on the back of the receiving portion, the feet 113 are first inserted through corresponding openings 106 in the receiving portion 103 and then via ribs 105 which on the opposite side of the receiving portion 103 are formed at its outer edge, are bent. This forms the clamping connection according to the invention, wherein the feet, once they have been applied once over the ribs, hold in the manner of retaining claws the socket nut 110 in place. The apertures 106 are sufficiently large that they allow the feet 113 to be pushed through in any acceptable position of the socket nut 110 to provide sufficient freedom of positioning for compensation in the two directions, that of the plane of the receiving area (ie, substantially perpendicular to the axis c). The openings 106 are preferably opening areas offset from the receiving opening 104, but may also be realized in the form of opening areas communicating with the central receiving opening 104.
    Referring to Fig. 6, a shim 120 serves to level-out the positioning. The shim 120 has the shape of a ring (in the example shown more specifically a cup with a central hole), which is preferably dTehsym-metric about an axis b, in the illustrated embodiment with a threefold symmetry. The shim 120 is mounted with the side visible in Fig. 4 (hereinafter referred to as "bottom") on the front side of the receiving area; for this purpose it has a number (in this case for example three) of supporting surfaces 122 which are each designed helically. These support surfaces 122 serve as a ramp for adjusting a height by rotating the Ausgjeichsscheibe 120, in cooperation with each associated helical counter-surface 108 of the receiving portion 103 (Fig. 3). The helical support surfaces and mating surfaces 122, 108 may be continuous or stepped as shown in FIG
    Example, which allows setting discrete altitude values with predetermined accuracy
    Referring again to Fig. 3, the receiving portion 103 has an annular portion containing the aforementioned helical mating surfaces 108 and a number of spring tongues 107. The resilient tongues 107 may be undercut on the side facing the aperture 104 and, when viewed as a whole, tapered be executed. This spring tongues realize a clip-like support for the shim 120 to hold it on the ramp formed by the helical mating surfaces 108, and thus serve as protection against loss of the element until the final assembly of the headlamp on the vehicle frame. The spring tongues thus serve as positioning security and transport protection for the shim.
    In this way, the shim 120 is placed on the receiving area 103 between the spring tongues 107 at the front of the receiving area 103, d.i. in the illustrated embodiment with respect to the socket nut 110, attachable. The shim 120 has on its upper side (i.e., the side which is intended to face away from the receiving element, see Fig. 1) an end face 121 which, in the assembled state, constitutes a stop for the fastening screw (fastening part).
    The assembly of the mounting assembly 103 is such that the desired correct position on the headlight component is determined, then the plug nut 110 by means of a mounting device (Fig. 26) is mounted in the correct position on the back of the receiving element 102, while the feet 113 on the Rip 105 be folded. For this purpose, a mounting device can be used with a suitable shape, which can provide the skilled person due to its general expertise. By this operation, the position of the axis c is set in the receiving element 102 in the two coordinates perpendicular to the axis c and secured against rotation. In addition, with the mounting means projections 109 can be formed to the back of the receiving portion 103, which serve to hold the base plate 111 in order to additionally stabilize the positioning of the socket nut. Then, the shim is placed on the receiving area 103. The axis b thus runs in the assembled state to the axis c of the plug nut 110 substantially parallel. By turning relative to the receiving region 103, the height of the end face 121 is set above the receiving region. This
    Prirjted: P12582: 29-05-2012 1E014.1 102012/50204 -13- realizes the compensation of the pick-up position in three directions, which maintains its once impressed position regardless of the final assembly (pre-fixing). The rotational position of the shim 120 is adjusted by means of grip protrusions 123, which are provided, for example, on the outer edge of the shim 120. In this way, the height of the stop along the axis c is set. In addition, by means of the grip projections 123 (which project outwardly between the spring tongues 107), the amount of possible rotational movement of the shim 120 is limited to avoid turning over the end of a ramp 122.
    26, shows the mounting device 500, which provides the prefixing of the mounting arrangement 101 to the headlight housing 2. The headlight - only a part of the headlight housing 2 is shown in FIG. 26 - is mounted on a stable positioning frame of the mounting device 500 at defined alignment points, which are preferably are defined by predetermined receiving points 501, 502 for the housing, placed in position and clamped stress-free. The Montageeinnchtung 500 has movable cross slide 503, 504, 505, which can be brought in a known manner by means of stop or measuring device in the required coordinates (not shown). That cross slide 504, which can reach the end position, is shaped to receive the plug nut 110 in an accessible position, for example in a receptacle on the cross slide 506, and bring it into the intended position; In this way, the tolerance (deviation) is compensated, which can exist between the headlight housing 2 and 3 carrier production-related. The movement of the cross slide elements 503, 504, 505 is in the order 1,2,3 as illustrated by the numbers in boxes in FIG. 26.
    After reaching position, a displaceable pliers head (thrust piece, bear) 505 is moved, which is ausgeftihrt that the retaining tabs 113 of the plug nut 110 are folded over and the hexagonal plug mat 111 is pressed with the plastic housing. The compression causes a permanent deformation on the plastic housing 109 (tab of the headlamp he housing, see Fig.3).
    All carriage or pincer movements can be carried out mechanically, pneumatically or hydraulically, depending on the desired or required degree of automation and effort.

    In a variant of the embodiment, the threaded portion 112 may also be facing the shim 120 or both sides, so that it passes through the base plate 111. Also, the threaded portion 112 may be in one variant, a pin with external thread, which is guided through the receiving opening, in which case, instead of the fastening screw or a fastening nut. occurs.
    7 to 12 show a second embodiment of a mounting arrangement 201 for a headlamp, wherein the shim is plastically deformable for adjusting the height
    Fig. 7 illustrates in a perspective view in partial section the attachment of the headlamp (which is of the same type as in the first embodiment), or more precisely its housing 2 on the support 3 of the vehicle body using the mounting assembly 201 according to the second embodiment. On the headlight housing 2 is a serving as a receiving element 202 tab in which a receiving area 203 is formed, on which the fastening assembly 201 is mounted. Again, by means of fixing means 201 prefixed to the housing 2, the compensation of the relative positioning of the fixing screw 4 (generally the fixing part) by which the headlamp is fixed to the support 3 takes place.
    8a and 8b show the prefastened to the headlight housing 2 mounting assembly 201 in relation to FIG. 1 enlarged perspective views. Here, Fig. 2a shows the " front " 9, the receiving element 202 without the components of the fastening arrangement is shown in a perspective view. The receiving element 202 has an opening 204 in the center of the receiving area 203, through which the fastening screw 4 is to be guided during final assembly. However, the receiving area 203 is designed specifically in a manner corresponding to the fastening arrangement 201, but simpler than in the first exemplary embodiment. The receiving region 203 has the basic shape of a structured annular disc, the additional holding structures, such as openings 206, for attaching the components of the mounting assembly 201, which are explained below. The opening 204 is made larger here, as it corresponds to the cross section of the screw 4, to allow adjustment / compensation of the position of the screw. - 15- PI2582
    Fig. 10 shows a plug nut 210, which serves as a connecting element according to the invention. The plug nut 210 is made of metal, for example, and has a similar shape as the plug nut 110 of the first exemplary embodiment, with a threaded portion 212 (axis c) located in the center of a base plate 211, which is also formed as an internal thread, but in this case on the same Side as the feet 213 is arranged; this side is in the assembled state, the back of the receiving area 203 faces. Again, the base plate 211 carries a number of (e.g., three) tongues or feet 213 disposed about the threaded portion 212 and initially oriented parallel to the axis c. The feet 213 are in turn plastically deformable, which allows insertion of the feet through corresponding openings 206 in the receiving region 203 from the rear side thereof and a bending of the ends of the feet on the front side of the receiving region 203, in a manner corresponding to the first embodiment. In the mounted state thus protrudes the threaded portion 212 through the Aufnahmeöffhung 204 at the front of the receiving area 203rd
    Referring to FIG. 11, a compensating body 220 serves as a compensating element in the sense of the invention. The compensating body 220 has a ring shape with respect to an axis b whose upper side 221 is flat and serves as an end face and stop for the fastening. The central opening 224 of the annular shape has on its inner edge a collar 222, which faces away from the end face 221, and thus towards the receiving area (with respect to the mounting position). On the outside of the ring mold, arranged uniformly along the circumference, are a number of pre-bent feet 223, which also face the receiving area and form flexible projections or tabs for adjusting the height of the compensating body 220. The feet 223 are for this purpose under the action of force along the axis b deformable. As can be seen in FIGS. 8 a and 8 b, the compensating body 220 is supported by the feet 223 on the receiving region 203. The feet 223 have on their outer side openings through which one end of a foot 213 of the plug nut 210 can be guided; through these openings receive the feet 223 a perforated or handle-shaped. The size of the collar 222 is suitably selected with respect to the threaded portion 212 so that the threaded portion 212 in the assembled state through the receiving opening 204 in the collar 222 protrudes. The thread must not protrude beyond the collar 222, more precisely the end face 221. The threaded portion 212 forms in cooperation with the collar 222 a guide in the direction of the axis c. The overlap of collar 222 and outer surface of threaded portion 212 increases stability
    Pniited: The joint, wherein the cylindrical outer surface of the threaded portion and the inner side surface of the collar 222 are preferably slightly spaced (clearance fit).
    Referring to FIG. 12, an intermediate disc 230 placed under the compensating body 220 on the receiving portion 203 prevents the metallic compensating body 220 from digging into the plastic material of the receiving portion 203. The intermediate disc 230 is preferably made of metal in one of the arrangement of the feet 220 of the compensating body 220 corresponding shape, such as hexagonal in the case of six feet 220th
    In order to pre-fix the fastening arrangement 201 of the second exemplary embodiment, the intermediate plate 230 is first placed on the front side of the receiving region 203 and then the compensating body 220 is placed thereon. After determining the desired correct position on the headlight component, the plug nut 210 is pressed by means of a mounting device (Fig. 27) in the correct position on the back of the receiving element 202, the feet 213 inserted through the openings 206 and inwardly over the edge of the washer 230th and each one of the feet 213 of the compensating body 210 are folded. This forms the clamping connection according to the invention, wherein the feet, once they have been attached and bent, hold in the manner of retaining claws, the entire fastening assembly 201 in place. The openings 206 are sufficiently large that they allow the feet 213 to be pushed through in any acceptable position of the plug nut 210 to provide sufficient freedom of positioning for compensation in the two directions, that of the plane of the receiving area (ie, substantially perpendicular to the axis c). The openings 206 are preferably opening areas offset from the receiving opening 204, but may also be realized in the form of opening areas communicating with the central receiving opening. This fixes the position of the plug nut 210 (as well as in the case of the plug nut 110) and thus the position of the axis c in two coordinates and also fixes them against twisting. Then, the balancing body 220 is placed on the front side of the receiving area 203. The height compensation is achieved at the compensation body 220 by the deformable feet 223, which are compressed by the force of the mounting device until the desired height adjustment is reached.
    This pre-fixation balances the pickup position in three directions, maintaining its once-imprinted position regardless of final assembly. Printed: 29-05-2012 £ 014.1 10 2012/50204
    FIG. 26 shows the mounting device 600, which provides the prefixing of the fastening arrangement 201 on the headlight housing 2. The headlamp - shown in Fig. 26 only a portion of the headlamp housing 2 - is placed on a stable positioning frame of the mounting device 600 at defined alignment points, which are preferably defined by predetermined receiving points 601, 602 for the housing, tightened and tension-free. The mounting device 600 has movable cross slides 603, 604, 605, which can be brought in the known manner by means of stop or measuring device in the required coordinates (not shown). that cross slide 604, which can reach the end position, is shaped to receive the plug nut 210 in an accessible position, for example in a receptacle 606 for the socket nut, which is fitted between cross slide 606 and the receiving element 202 on the headlight housing 2, and these in the first two coordinates to the intended position. Then, with respect to the third coordinate to be compensated, it is guided by means of an optical or length-measuring scanner 607 (for example height sensor) to the receiving lug 202 of the headlamp housing, and e.g. hydraulically locked. In this way, the tolerance (deviation) is compensated, which can exist between the headlight housing 2 and 3 carrier production-related.
    After reaching the position of the plug-in nut 210, the intermediate plate 230 and the equalizer ring 220 are grasped by the plug-in nut 210 and placed on the receiving element 202. An e.g. Hydraulically moved plunger 605 squeezes the balancing ring 220 up to a fixed stop (this corresponds to the fixed coordinates of the screwing coordinates of the carrier 3), thus the height compensation is determined. Balanced by appropriate spring force (the punch 608 is spring-loaded), the tabs 213 of the plug nut 210 are folded over the compensation body 220 and the washer 230 and pressed together in the same punch movement, whereby the whole compensation system is clamped to the receiving element 202 on the headlight housing 2. After the clamping process, the compensation element is aligned and fixed in the required coordinates to match carrier 3.
    The movement of the cross slide elements 603, 604, 605 is in the order of 1,2, 3 as illustrated by the numbers in boxes in FIG. iPrinted: 29-05-2012 £ 014.1 102012/50204 P12582 -18-
    All carriage or pincer movements can be carried out mechanically, pneumatically or hydraulically, depending on the desired or required degree of automation and effort.
    After assembly, feet 220 maintain the preset press position; In particular, the extent of deformability is chosen so that they withstand the Anschraubdruck during assembly of the headlamp or the housing 2 on the support 3 (tightening the mounting screw 4). A deformation of the feet 223 of the compensation body 220 can thus be excluded because the force exerted by the mounting means for deforming the feet 223 are greater than the contact pressure of the fastening screw, which connects the body part with the prefixed element components which are attached to the receiving element 202 ,
    13 to 19 show a third embodiment of a mounting arrangement 301 for a headlamp, wherein a connecting screw 310 serves as a connecting element in the context of the invention. The connecting screw 310 is detected regardless of the position of the receiving member 302 (which may optionally have a misalignment) at the desired correct position. The end face 311 of the head 314 of the connecting screw 310 forms an end face and serves as a stop in the sense of the invention for the carrier 3 (see Fig. 13). In the head 314, preferably starting from the end face 311, the connecting screw also has a threaded part 312, for example an internal thread, to which the fastening part, for example the fastening screw 4, can be fastened.
    The example of this embodiment demonstrates that the attachment according to the invention can be made in any spatial position. For example, in this case, the support member 3 is lower with respect to the assembly 301 and is held by a fastening screw 4 from below, the latter being inserted into the internal thread 312.
    In a modification, this fastening arrangement can also be used in the case of a laterally hung fixing strap of the headlight housing.
    Referring to FIGS. 14a and 14b, the fastening assembly 301 according to this third embodiment further comprises two nuts 321, 322 which are arranged on opposite sides of the receiving portion 303 in the mounted state and mounted on the connecting screw 310, which passes through the receiving opening 304. The mothers IPrinted: 29-05-2012 £ 014.1 10 2012/50204 P12582 -19- 321, 322 together with a driver spring 330 a compensation element 320 in the context of the invention (Fig. 14b). The components 310, 321, 322, 330 of Befestigungsanord-mmg 301 are preferably made of metal, while the receiving element 302 is in turn made of the plastic material of the headlight housing 2.
    Fig. 15 shows the receiving element 302 with the receiving area 303, which in turn has the basic shape of a structured annular disc. In this embodiment, apart from the receiving opening 304 itself, no further structures of the receiving area 303 for attaching the fixing arrangement 301 are required.
    Referring to FIG. 16, the connecting screw 310 has two counter-rotating threads 313 along its shank. The threaded portion 312 formed in the head 314 and a portion of the shank is not visible in FIG. 16, but can be seen in FIG. 14a.
    The nuts 321, 322 are shown in FIGS. 17, and 18. The first nut 321 (Fig. 17) is called an adjusting nut. The second nut 322 (Fig. 18) is a lock nut and has a shape that allows gripping with a tool train, such as a hexagon. Both nuts 321, 322 each have a structuring 323 on at least one of their side surfaces, for example in the form of radially outwardly or radially extending grooves or notches. In addition, circumferential rib or groove-shaped structures 324 may be provided, preferably in the form of elevations along concentric circles which improve the hold of the mothers on the surface of the receiving area 303 in the prefixed / assembled state and thus as a safeguard against slippage after prefixing of the fastening arrangement 301 serve. The internal threads of the nuts 312, 322 are opposite to each other and each correspond to one of the two threads 313 of the connecting screw 310th
    Fig. 19 shows the driver spring 330. The two ends 331 of the driver spring are bent outwards, preferably over a length which substantially corresponds to the diameter of the spring wire. In addition, it is advantageous if the ends have angled end surfaces angled, for example, at an angle W of about 160 °. This particular design of the ends 331 allows them to better engage with the mentioned groove or notch structure 323 of the nut. When assembled (see Figures 14a and 14b), the nuts 321, 322 are located on opposite sides of the mounting area. When the nuts are mounted on the connecting bolt, they move towards each other by a synchronous rotation, due to the mutually opposite Windungsrichtungen, and can be determined on the receiving portion 303 for forming a laterally adjustable clamping connection.
    The driver spring 330 forms a compressible along the axis c, arranged between the nut 321,322 spring structure. The ends of the spring 330 engage the structures 323 on the facing surfaces of the nuts 321, 322, whereby the rotation of the one nut 322 transmits in the same direction to the other 321. In other words, the adjusting nut 321 is rotated by turning the locking nut 322 via the driver spring 330. In this way, the rotations of the nuts 321, 322 are coupled to each other about the axis c. Due to the obtuse-angled locking of the ends 331 of the spring 330 in the groove / notch structures 323 of the nut, however, a further rotation of the locking nut is possible according to the principle of the ratchet when the end position of the adjusting nut is reached and this can not continue to rotate. This provides the advantage of automatically resulting positioning of the adjusting nut by the driver spring.
    It is noted that the cam spring 330 has primarily the purpose of entrainment by a compressible structure and does not perform spring force tasks. The driver spring 330 is made of a conventional spring steel material, for example, but it is also possible to use a sufficiently rigid plastic spring instead of a steel spring with angled ends. In addition, in one variant, the spring structure can also be more continuous, so that it rests on the end face of a nut with several ends.
    To pre-fix the mounting assembly 301 of the third embodiment is screwed onto the adjusting nut 321 on the connecting screw, then the driver spring 330 is inserted over the shaft and the shaft passed through the receiving opening 304. Then the locking nut 322 is applied, but not tightened for the time being. After determining the desired correct position on the headlight component, the connecting screw 310 is held in the correct position. When held in this position connecting screw 310 now the locking nut 322 is rotated; In this case, the spring 330 tiberträgt the rotational movement on the adjusting nut 321 until the latter because of the higher thread pitch first to stop at A receiving area 303 comes The locking nut 322 is further rotated, the spring now in the manner of a ratchet on the structure
    Printed: 29-05-2012 E014.1 10 2012/50204 PI2582 -21- adjusting nut 321 is running. This thus allows further rotation of the locking nut 322 (with slightly increased force to overcome the resistance of the spring) until it comes to the stop and so the clamping connection of the mounting assembly 301 is carried out. Clamping and positioning thus takes place in one operation. The position of the end surface 311 is thus adjustable along the axis c using the compensating member 320.
    The adjusting nut 321 thus adapts automatically to the possibly incorrect position of the receiving element 302 by the driver spring 322.
    In a variant, the driver spring 330 may be omitted; in this case, the adjusting nut 321 must be independent of the lock nut 322, e.g. be tightened in the required position in a separate assembly operation.
    20 to 25 show a fourth embodiment of a mounting arrangement 401 for a headlight, in which - similar to the third embodiment 301 - a connecting screw 410 serves as a connecting element according to the invention. The end face 411 of the head 414 of the connecting screw 410 also forms an end face here and serves as a stop in the sense of the invention for the carrier 3 (see FIG. In the head 414, the connecting screw has a threaded part 412, for example an internal thread, to which the fastening part, for example the fastening screw 4, can be fastened.
    Referring to FIGS. 21 a and 21 b, the fastening arrangement 401 according to this fourth exemplary embodiment comprises, in addition to the connecting screw 410, a clamp in the form of a plug nut 420 with a hollow guide which serves as a compensating element in the sense of the invention, and a lock nut 430 for fixing the connecting screw 410. The components 410, 420, 430 of the fastening arrangement 401 are preferably made of metal.
    FIG. 22 shows the receiving element 402 with the receiving region 403, which in turn has the basic shape of a structured annular disk. The receiving opening 304 is disposed near a peripheral edge 405 of the receiving area.

    Referring to FIG. 23, the connecting screw 410 has a threaded part 412 formed in the head 414 and a part of the shaft, which serves as a fastening thread for attaching the fixing screw 4. In addition, the connecting screw 310 has along its shank two threaded sections 413, 415, which respectively correspond to internal threads of the plug-in nut 420 or lock nut 430. The threaded portions 413, 415 may be made in the same direction or in opposite directions.
    FIG. 24 shows the plug nut 420 in a sectional view according to a section along the vertical center plane. The stub nut 420 has a U-shaped body 423 on each side with an attached hollow guide member 424, 425; Both guide parts together form a hollow guide 421 with axis c1. The upper guide part 424 in FIG. 24 also has an internal thread 422 that corresponds to the external thread 413 of the connecting element 410. The U-shaped body 423 forms a clamp structure, whereby the plug-in nut can be attached laterally to the receiving area 403 in the manner of a clamp. 25, the lock nut 430 is shown, which has an internal thread corresponding to the thread 415, so that the lock nut 430 can be attached to the end of the hollow guide 421 of the plug nut 420 (see FIG
    For pre-fixing the fastening arrangement 401 of the fourth exemplary embodiment, the plug-in nut 420 is pushed over the peripheral edge 405 of the receiving element 402 onto the receiving area 403. In this case, the plug nut 420 has a loose fit, which allows positioning of the axis c 'of the hollow guide 421 with respect to the two coordinates, which correspond to the plane of the receiving area 403 positioned. Then, the connecting bolt 410 is screwed into the internal thread 422 until the desired height position of the end face 411 is reached (third coordinate). The correct position with respect to the first two coordinates is optionally set before or after the height position is adjusted, but preferably before. With the connecting screw 410 held, the locking nut 430 is then slipped onto the thread 415 on the side opposite the head 414 and tightened; in this way, the position is fixed and ensures a tight fit of the mounting assembly 401. Here, the clamp connection and the countering takes place in one operation. iPiinted: 29-05-2012 lEÖ14; 1 102012/50204 PI2582 -23-
    The position of the end surface 411 is thus adjustable along the axis c (which coincides in the prefixed state with the axis e 'of the hollow guide 421) using the plug nut 420, and the mounting assembly 401 maintains its position even during the subsequent final assembly (ie Mounting the headlight housing 2 on the support 3 by means of the screw 4 using the mounting assembly 401). Of course variants are possible in all embodiments. Thus, the position of the threaded portion 112, 212, 312, 412 may vary depending on the requirements. Also, the threaded portion may be a pin with external thread, instead of an internal thread, in which case instead of the fastening screw or a fastening nut. occurs.
