Description

  The present invention relates to a sliding door temporary holding jig for temporarily holding a sliding door on an automobile body.

  A sliding door is used as a door for entering and exiting a passenger compartment provided on the side of the vehicle body. The sliding door is held so as to be openable and closable in the front-rear direction of the vehicle body along a rail provided on the vehicle body. In the painting process of an automobile manufacturing factory, a sliding door is temporarily assembled to the vehicle body in order to match colors, and in this state, the vehicle body and the sliding door are sequentially coated.

  The temporary assembly, in other words, the temporary holding is performed via an apparatus or a jig. Examples of this type of apparatus or jig include those disclosed in Patent Documents 1 and 2. If the sliding door can only be displaced in the longitudinal direction of the vehicle body, it is difficult to paint the inner surface of the sliding door (the surface facing the passenger compartment) and the opening of the vehicle body (the part where the sliding door is seated and blocked). It is. Accordingly, the apparatus or jig generally includes a configuration in which the slide door is moved in a direction away from the vehicle body with respect to the width direction of the vehicle body.

Japanese Patent Laid-Open No. 2000-16086 JP 2007-120189 A

  The device described in Patent Document 1 has an auxiliary guide rail attached to the center rail and a hanger for hanging the slide door in order to move the slide door in a direction away from the vehicle body. The auxiliary guide rail is difficult to install unless it corresponds to the shape of the vehicle body. That is, this device is poor in versatility. Moreover, the hanger which can suspend a sliding door is generally large sized. For this reason, the apparatus becomes large and equipment investment increases.

  On the other hand, the jig of Patent Document 2 can be opened and closed in a state where the slide door is held on the center pillar of the vehicle body like a hinged door, and the load of the slide door is used as a temporary fixing jig having a hinge function. Therefore, the structure is complicated and large. Moreover, since it has a model-specific structure, it is necessary to prepare jigs according to the number of production models. Furthermore, since the jig is heavy, there is a concern that the conveyance cost for removing the jig from the finished vehicle body and slide door and attaching it to the slide door to the next vehicle body to be loaded increases.

  The present invention has been made to solve the above problems, and is small and lightweight.For this reason, for example, an operator temporarily holds a sliding door on a vehicle body for work such as painting or repairing, An object of the present invention is to provide a sliding door temporary holding jig that can easily release the temporary holding of the sliding door.

In order to achieve the above object, the present invention is a sliding door temporary holding jig for temporarily holding a sliding door in a state where the upper and lower sides of the sliding door are supported by an automobile body,
A first arm connected to the sliding door;
A second arm having one end rotatably connected to the first arm via a connecting shaft;
A bracket connected to the other end of the second arm and engaged with a guide rail provided on the automobile body for guiding the sliding door;
Have
The second arm is detachably attached to the bracket.

  By fixing the first arm and the second arm that are rotatably connected via the connecting shaft to the bracket, the separation distance of the slide door can be increased. For this reason, workability around the door is improved. Moreover, since the structure of the jig is simplified, the size and weight are reduced, and handling is improved.

  In this configuration, a part of the insertion hole formed in the first arm or the second arm for passing the connecting shaft is a long hole, and the connecting shaft is displaceable along the long hole. It is preferable.

  When the sliding door is held on the vehicle body via the sliding door temporary holding jig having such a configuration, when the sliding door is displaced to the rear side of the vehicle body, the connecting shaft moves along the elongated hole through the connecting shaft. To displace. Accordingly, the first arm tilts with respect to the second arm or the second arm tilts with respect to the first arm. That is, the first arm or the second arm tilts relative to each other.

  Due to this tilting, the separation distance from the vehicle body on the rear side of the slide door becomes larger than that on the front side. As described above, in the present invention, when the sliding door is displaced in the opening direction, the rear side of the sliding door is spontaneously largely separated from the vehicle body. Accordingly, in the vehicle body, it is easy to perform work (for example, painting) on the opening portion on which the slide door is seated and the inner surface of the slide door.

  Further, the slide door temporary holding jig can be composed of the first arm, the connecting shaft, and the second arm, and thus is small and lightweight. Therefore, for example, even if the sliding door temporary holding jig is removed from the finished vehicle body and slide door and then attached to the vehicle body and slide door to be painted next time, it may be a burden on the operator. Avoided.

  In order to engage the bracket with the guide rail, for example, a roller inserted into the guide rail so as to be able to roll may be used. That is, the vehicle body is provided with a lower rail, a center rail, and an upper rail from below, while the slide door is provided with a lower roller, a center roller, and an upper roller from below. The lower roller, the center roller, or the upper roller is held by the bracket, and the roller held by the bracket is housed in the rail, whereby the bracket is engaged with the guide rail.

  When the lower rail is selected as the rail, the lower roller is selected as the roller held by the bracket. Similarly, when the center rail is selected, the center roller is selected, and when the upper rail is selected, the upper roller is selected.

  Among these combinations, it is preferable to select a combination of a center rail and a center roller. This is because the sliding door is held by the vehicle body in a balanced manner.

  According to the present invention, the first arm and the second arm, which are rotatably connected via the connecting shaft, are fixed to the bracket, so that the separation distance of the slide door can be increased. For this reason, workability around the door is improved. For example, it becomes easy to perform operations such as painting on the side surface of the vehicle body on which the slide door is seated and the inner surface of the slide door.

  Moreover, since the structure of the jig is simplified, the size and weight are reduced, and handling is improved. For this reason, it becomes easy to temporarily hold the sliding door on the vehicle body or to release the temporary holding of the sliding door for work such as painting and repair.

It is a schematic diagram shown. It is a partially cutaway rear view showing the state shown in FIG. 8B. It is the principal part perspective view which showed the state shown to FIG. 8C.

  Hereinafter, preferred embodiments of the sliding door temporary holding jig according to the present invention will be described in detail with reference to the accompanying drawings.

  FIG. 1 is a main part schematic perspective view showing a state in which a sliding door 12 is temporarily held on an automobile body (vehicle body) 14 by a sliding door temporary holding jig 10 according to the present embodiment. They are a rear view and a perspective view, respectively, with the viewpoint being the rear of the vehicle body 14. First, the vehicle body 14 and the slide door 12 will be outlined.

  An opening 16 is formed on the side surface of the vehicle body 14. When the slide door 12 is seated in the opening 16, the slide door 12 is fully closed.

  A lower rail 18 is provided below the opening 16 in the vehicle body 14, while an upper rail 20 is provided above (see both FIG. 2). Further, a center rail 22 (see FIGS. 1 and 3) is provided on the rear side of the opening portion 16 in the vehicle body 14 at a substantially middle portion in the height direction of the vehicle body 14. On the other hand, the slide door 12 includes a lower roller 24 and an upper roller 26 that are rotatably engaged with the lower rail 18 and the upper rail 20. These lower rail 18, upper rail 20, center rail 22, lower roller 24, and upper roller 26 are well known, and therefore detailed description thereof is omitted.

  The slide door 12 further includes a center roller 28 (see FIG. 5) that is movably engaged with the center rail 22, which will be described later.

  As shown in FIG. 4 in which the main part is enlarged, the center rail 22 is formed with a main groove 30 opened to the outside of the vehicle body 14 and a guide groove 32 opened downward. On the other hand, the center roller 28 has a main roller 34 and a sub roller 36, and the main roller 34 rolls on the bottom surface of the main groove 30, and the sub roller 36 rolls on both side surfaces of the guide groove 32.

  Next, the sliding door temporary holding jig 10 will be described.

  5 and 6 are a schematic overall perspective view and an exploded perspective view of the sliding door temporary holding jig 10, respectively. However, FIG. 6 shows an angle different from FIG. 5 (the viewpoint is the VI direction in FIG. 5).

  The sliding door temporary holding jig 10 includes a first arm 40 and a second arm 44 connected to the first arm 40 by a connecting shaft 42. The first arm 40 and the second arm 44 are relatively rotatable about the connecting shaft 42. The first arm 40, the connecting shaft 42, and the second arm 44 constitute a hinge.

  The first arm 40 includes a first bar 46 and a second bar 48 extending in parallel with each other, and a first reinforcing bar 50 and a second reinforcing bar 52 bridged by the first bar 46 and the second bar 48. It is a long object having a substantially ladder shape, and a door side bracket 54 is joined to one end of the first bar 46 and the second bar 48 therein. That is, the door-side bracket 54 is provided at one end in the longitudinal direction of the first arm 40.

  A through hole 56 is formed through the door side bracket 54, and a mounting bolt 58 is passed through the through hole 56. As will be described later, the first arm 40 is connected to the slide door 12 via the door-side bracket 54 by screwing the mounting bolt 58 into the bolt hole of the slide door 12.

  In the other end of the first bar 46 and the second bar 48, engagement holes 60 and 62 through which the connecting shaft 42 is passed are respectively formed. The diameters of the engagement holes 60 and 62 substantially correspond to the diameter of the connecting shaft 42. Therefore, it is avoided that the center of the connecting shaft 42 and the centers of the engagement holes 60 and 62 are displaced. The connecting shaft 42 can rotate in the engagement holes 60 and 62.

  One end of the second arm 44 is separated into a substantially Y shape. Hereinafter, the separated tip portions are referred to as a first engagement portion and a second engagement portion, and reference numerals 64 and 66 are used.

  The first engaging portion 64 is formed with an engaging hole 68 through which the connecting shaft 42 passes. The diameter of the engagement hole 68 is set to be slightly larger than the diameter of the connecting shaft 42 as shown in FIG. 7A. Therefore, a so-called play exists between the engagement hole 68 and the connecting shaft 42. The engagement hole 68 is provided so as to be able to absorb a positional shift between the center of the engagement hole 68 and the center of the connecting shaft 42. Of course, the connecting shaft 42 can rotate in the engagement hole 68.

  An elongated hole 70 through which the connecting shaft 42 passes is formed through the second engaging portion 66. As can be seen from FIG. 5, the longitudinal direction of the long hole 70 is a direction substantially orthogonal to the longitudinal direction of the first arm 40 (the first bar 46 and the second bar 48).

  As shown in FIG. 7B, the longitudinal dimension of the long hole 70 is larger than the diameter of the connecting shaft 42, and the dimension in the short direction substantially corresponds to the diameter of the connecting shaft 42. Therefore, the second engaging portion 66 can be displaced along the longitudinal direction of the long hole 70. As the second engagement portion 66 is displaced in this way, the second arm 44 tilts in the direction indicated by the arrow A in FIGS. 2, 4 and 7B.

  The second arm 44 is formed with so-called meat thefts 72a and 72b for weight reduction. The other end is slightly bent so as to be close to the first arm 40 side (see FIGS. 5 and 6). At the other end, screw holes 74 and 76 are formed through.

  A vehicle body side bracket 82 including a bracket body 78 having a substantially triangular shape in plan view and a roller support member 80 is provided at the other end portion of the second arm 44. The bracket body 78 has screw holes 83 and 84 formed therethrough, and nuts 88 are screwed into the screw holes 83 and short connection bolts 86 passed through the screw holes 74 of the second arm 44. As a result, the bracket body 78 is coupled to the second arm 44.

  One roller support member 80 includes an engagement end portion 90 in which an insertion slot 89 is formed, a substantially horizontal bottom portion 92 extending from the engagement end portion 90 toward the center rail 22, and the bottom portion 92. And a roller holding portion 94 rising substantially vertically. The roller support member 80 is supported by the bracket body 78 by connecting the engaging end 90 to the bracket body 78 via a support shaft 96. Note that the insertion elongated hole 89 is passed through the distal end of a long fixing bolt 98 passed through the threaded hole 76 of the second arm 44 and the threaded hole 84 of the bracket body 78, and a nut is inserted into the distal end. 100 is screwed together.

  The vehicle body side bracket 82 has a bracket body 78 and an engaging end 90 coupled in a hinged state by a support shaft 96, and is originally attached to the attachment portion 12a of the slide door 12 to connect the slide door 12 and the vehicle body 14 together. To do.

  Further, the fixing bolt 98 is a unit in which the hinge end 90 and the vehicle body side bracket 82 are connected to each other integrally with the second arm 44 in a fixed state. That is, the engagement end 90 and the vehicle body side bracket 82 are originally hinged by the support shaft 96, but when the sliding door temporary holding jig 10 is attached, its function is eliminated by the fixing bolt 98. ing.

  A main roller 34 and two sub rollers 36 constituting the center roller 28 are rotatably supported on the roller holding portion 94. The center roller 28 is accommodated in the center rail 22 (see FIG. 4), the main roller 34 rolls on the bottom surface forming the main groove 30 of the center rail 22, while the sub-roller 36 forms both guide grooves 32. Roll on the wall.

  The sliding door temporary holding jig 10 according to the present embodiment is basically configured as described above. Next, the function and effect will be described.

  The vehicle body 14 and the slide door 12 are individually transported to the painting station, and then temporarily assembled by the slide door temporary holding jig 10 described above. That is, the slide door 12 is temporarily held by the vehicle body 14.

  First, the center roller 28 held by the roller holding portion 94 of the roller support member 80 constituting the vehicle body side bracket 82 is accommodated in the center rail 22 (see FIG. 4). At this time, as described above, the main roller 34 of the center roller 28 is accommodated in the main groove 30, while the sub roller 36 is accommodated in the guide groove 32.

  Next, the lower roller 24 and the upper roller 26 provided on the slide door 12 are inserted into the lower rail 18 and the upper rail 20 (see FIG. 2) provided on the vehicle body 14. As a result, the slide door 12 is supported by the vehicle body 14 via the lower rail 18 and the upper rail 20.

  Next, the mounting bolt 58 passed through the through hole 56 of the door side bracket 54 (see FIGS. 5 and 6) is screwed into the bolt hole formed in the mounting portion 12a of the slide door 12. With this screwing, the first arm 40 is connected to the slide door 12 via the door-side bracket 54 (see FIGS. 1 to 4). As described above, the attachment portion 12a of the slide door 12 is originally a place where the vehicle body side bracket 82 is attached.

  As described above, the second arm 44 of the sliding door temporary holding jig 10 is supported by the vehicle body 14 and the first arm 40 supports the sliding door 12. That is, the slide door 12 is supported by the vehicle body 14 via the slide door temporary holding jig 10 in addition to the lower rail 18 and the upper rail 20 described above.

  As shown in FIG. 8A, when the slide door 12 closes the opening 16, the first arm 40 and the second arm 44 are in a closed state, and the second arm 44 is not tilted, and the first arm 40 is not tilted. Is the closest to. The separation distance from the rear vehicle body 14 in the slide door 12 at this time is L0 (= 0).

  In this state, a painting robot (not shown) operates to paint the outside of the vehicle body 14 and the slide door 12.

  When the outer coating is finished, the slide door 12 is then displaced rearward of the vehicle body 14 as shown in FIGS. 8B and 9 in order to coat the opening 16 and the inner surface of the slide door 12. At this time, the separation distance from the vehicle body 14 behind the slide door 12 is L1.

  Of course, at this time, the lower roller 24 and the upper roller 26 roll on the lower rail 18 and the upper rail 20, respectively, and the center roller 28 rolls on the center rail 22. That is, the main roller 34 rolls on the bottom surface of the main groove 30, and the sub roller 36 rolls on both side walls of the guide groove 32.

  When the sliding door 12 is displaced toward the rear of the vehicle body 14, the upper end portion of the connecting shaft 42 constituting the sliding door temporary holding jig 10 is formed into a long hole formed in the second engaging portion 66 of the second arm 44. It is displaced along the longitudinal direction of 70. As described above, the longitudinal direction of the long hole 70 is a direction substantially orthogonal to the longitudinal direction of the first arm 40 (the first bar 46 and the second bar 48), and the sliding door temporary holding jig 10 slides. In the state supported by the door 12 and the vehicle body 14, it extends along the width direction of the vehicle body 14.

  On the other hand, the lower end portion of the connecting shaft 42 is inserted into the engaging hole 68 substantially corresponding to the diameter of the connecting shaft 42 in the first engaging portion 64. For this reason, the state where the center of the connecting shaft 42 and the center of the engagement hole 68 are substantially coincident is maintained.

  As a result of the above phenomenon, the connecting shaft 42 tilts (see arrow A in FIG. 4). With this tilting, the rear side of the slide door 12 is separated from the vehicle body 14 as compared to the front side. That is, the slide door 12 is not displaced in parallel with the longitudinal direction of the vehicle body 14 but is displaced so as to form a substantially “C” shape with two pieces.

  The degree of tilting of the connecting shaft 42 increases as the slide door 12 is displaced rearward. Correspondingly, as shown in FIG. 8C, FIG. 8D and FIG. 10, the separation distance from the vehicle body 14 on the rear side of the slide door 12 is increased to L2 (L0 <L1 <L2). Further, the front side of the slide door 12 has a larger separation distance from the vehicle body 14 than when the slide door 12 is displaced parallel to the longitudinal direction of the vehicle body 14.

  2, 8D and 10, that is, when the sliding door 12 is fully opened, the painting robot (not shown) operates, and the paint spraying part of some painting robots faces the opening 16 of the vehicle body 14. The paint spraying part of another part of the painting robot faces the inner surface of the slide door 12. And a coating material is injected from each coating material injection part. Since the slide door 12 is greatly separated from the vehicle body 14, the coating on the opening 16 and the inner surface of the slide door 12 is remarkably easy.

  After painting is completed, the slide door 12 is displaced forward and is in a fully closed state that closes the opening 16. Thereafter, the mounting bolt 58 is loosened and detached from the slide door 12, and the center roller 28 is removed from the center rail 22, whereby the slide door temporary holding jig 10 is removed from both the slide door 12 and the vehicle body 14. .

  When subsequently painting another vehicle body 14 and the slide door 12 held by the vehicle body 14, the slide door temporary holding jig 10 released from holding as described above is attached to the slide body 12. It can be handled when temporarily holding. That is, when this sliding door temporary holding jig 10 is used, a hanger as described in Patent Document 1 is not necessary. For this reason, an apparatus does not become large scale and capital investment does not soar.

  Moreover, in the sliding door temporary holding jig 10, the roller of the vehicle body 14 (for example, the center roller 28) may be used, so that an auxiliary rail having a shape corresponding to the shape of the vehicle body 14 is not necessary. That is, since it can be used regardless of the shape (vehicle type) of the vehicle body 14, it is excellent in versatility.

  Moreover, as will be understood from FIGS. 1 to 4, the sliding door temporary holding jig 10 according to the present embodiment has a small shape, and thus is lightweight. Therefore, it is easy to perform the above-described attachment / removal operations continuously, so that the burden on the operator is avoided.

  After all, the sliding door temporary holding jig 10 according to the present embodiment is small and lightweight, so it does not burden the operator, and is excellent in versatility. There is an advantage that painting becomes easy.

  The present invention is not particularly limited to the above-described embodiment, and various modifications can be made without departing from the gist of the present invention.

  For example, in this embodiment, the center roller 28 is used, but the lower roller 24 or the upper roller 26 may be used.

  Further, the sliding door temporary holding jig 10 can be used outside a painting process or an automobile manufacturing factory. That is, for example, in an automobile repair service factory, the sliding door 12 may be used for holding the vehicle body 14.

  Further, the long hole 70 may be formed in the second bar 48 of the first arm 40.
