Description

  The present invention relates to an assembling jig and an assembling method for assembling lid members such as a back door and a hood to a vehicle body.

  A lid member such as a back door or a hood is attached to an opening of the vehicle body through a hinge or the like so as to be opened and closed. If the lid member is not accurately positioned with respect to the vehicle body when the lid member is assembled to the vehicle body, the gap formed at the boundary between the lid member and the vehicle body becomes non-uniform, and the appearance becomes poor. In particular, if the positioning accuracy of the lid member and the vehicle body in the vehicle width direction is low, the gap formed at the boundary between the lid member and the vehicle body becomes asymmetrical on the left and right sides, which is very noticeable.

  In the actual assembly process of the lid member, a dimensional tolerance is generated in the vehicle body due to deformation or an assembly error. Therefore, it is necessary to position the lid member for each vehicle body. For example, Patent Document 1 discloses an assembling jig that uses a center position in the vehicle width direction of an actual vehicle body as a positioning reference.

  However, even if the center of the lid member and the vehicle body in the vehicle width direction is aligned using the assembly jig shown in Patent Document 1, the assembly may be poor. For example, when a striker is provided on the lid member and a lock member that locks the lid member by engaging with the striker is provided on the vehicle body, the positions of the striker provided on the lid member and the lock member provided on the vehicle body are If it deviates, the striker cannot be mounted on the lock member, resulting in poor assembly.

  For example, when the lid member is made of sheet metal, even if the position of the striker and the lock member is slightly deviated with the lid member assembled to the vehicle body, the position of the striker is made fine by plastically deforming the lid member made of sheet metal. Can be adjusted. However, when the lid member is formed of a material that is not easily plastically deformed, such as a glass hatch or a resin hood, the position of the striker cannot be finely adjusted by plastic deformation. For this reason, when assembling the glass hatch or the like to the vehicle body, it is necessary to assemble not only the center position of the two but also the position where the striker and the lock member are aligned. Of course, even when a lid member made of sheet metal is assembled, if the striker and the lock member can be assembled with high accuracy, fine adjustment by plastic deformation can be omitted, and productivity can be improved.

  However, it is not easy to align the striker and the lock member while aligning the center position in the vehicle width direction of the lid member and the vehicle body using the assembly jig as shown in Patent Document 1 above. In addition, the workability of assembly is inevitable.

  The problem to be solved by the present invention is to provide an assembling jig and an assembling method capable of easily assembling a lid member having a striker to a vehicle body.

The present invention made to solve the above-mentioned problems is an assembly jig for assembling a lid member provided with a striker to a vehicle body , and is provided in holes of the vehicle body provided at two locations separated in the vehicle width direction. A pair of locking portions that are inserted and locked and that can adjust the interval in the vehicle width direction, a centering mechanism that sets a vehicle width direction center portion of the pair of locking portions, and the vehicle width direction center portion as a reference It has a pair of support pieces provided at predetermined positions in the vehicle width direction, and by placing a striker between the pair of support pieces, the movement of the striker in the vehicle width direction is restricted, and the striker is placed at the predetermined position in the vehicle width direction. the striker positioning portion for positioning a provided in the same vehicle width direction position as the striker positioning portion, and a locking positioning unit for positioning the locking member for locking the striker該車widthwise position, the lower end portion of the Futamono member is placed And a mounting portion, in a state of locking the pair of locking portions to the vehicle body, placing the lower end of the Futamono member is erected on the placing section, the upper end portion of the Futamono member in this state The lid member can be positioned with respect to the vehicle body by tilting forward and inserting the striker of the lid member between the pair of support pieces of the striker positioning portion .

  Thus, since a pair of latching | locking part can adjust a vehicle width direction space | interval, a pair of latching | locking part can be latched to the predetermined location of a vehicle body according to an actual vehicle body. Then, a striker positioning portion is provided at a predetermined position in the vehicle width direction with respect to the vehicle width direction center portion of the pair of locking portions, and the lid member is attached to the vehicle body by attaching the striker of the lid member to the striker positioning portion. On the other hand, it can be positioned in the vehicle width direction. For example, when the striker is provided in the vehicle width direction center portion of the lid member, the striker positioning portion may be provided in the vehicle width direction center portion of the pair of locking portions. Further, when the striker is provided at a position offset from the center part in the vehicle width direction of the lid member, the striker positioning part is provided at a position offset by an equal amount from the center part in the vehicle width direction of the pair of locking parts. Good.

  Moreover, since the lock positioning part is provided in the same vehicle width direction position as the striker positioning part in the above assembly jig, the width direction position of the striker attached to the striker positioning part and the lock positioning part are attached. The position of the lock member in the width direction can be matched. That is, according to the above assembling jig, by simply mounting the striker on the striker positioning portion, the lid member is positioned in the vehicle width direction with respect to the vehicle body, and at the same time, the striker and the lock member are aligned in the vehicle width direction. Can do.

  As described above, the present invention is a method for assembling a lid member provided with a striker to a vehicle body, the step of setting the vehicle width direction center portion of the vehicle body, and the vehicle width direction based on the vehicle width direction center portion A method of assembling a lid member, comprising: positioning a striker and a lock member that locks the striker at a predetermined position; and attaching the lid member and the lock member to the vehicle body in a state where the striker and the lock member are positioned in the vehicle width direction. It can also be characterized as

  As described above, according to the assembling jig and the assembling method of the present invention, the positioning of the lid member with respect to the vehicle body and the positioning of the striker with respect to the lock member are completed simultaneously only by mounting the striker on the striker positioning portion. be able to. Thereby, the workability of assembling the lid member to the vehicle body is improved, and the productivity of the vehicle is enhanced.

Both ends of the third link 73 are rotatably attached to inner ends in the vehicle width direction of the pair of second links 72 and 72, respectively. A central portion in the longitudinal direction of the third link 73 is rotatably attached to a central portion in the vehicle width direction of the main body portion 10 via a bearing 74.

  For example, when one of the locking portions 20 slides inward in the vehicle width direction, the other locking portion 20 also has an equal amount inward in the vehicle width direction via the first link 71, the second link 72, and the third link 73. Slide. Thereby, even when the vehicle width direction interval of the pair of locking portions 20 is changed, the vehicle width direction center portion P of the pair of locking portions 20 is always the vehicle width direction center portion of the main body portion 10 (that is, the third link 73). Coincides with the rotation center 74a).

  The striker positioning part 30 positions the striker 7 provided in the glass hatch 4 in the vehicle width direction. The striker positioning portion 30 is disposed at a predetermined position with respect to the vehicle width direction central portion P of the pair of locking portions 20. In this embodiment, the striker positioning portion 30 is the vehicle width direction central portion P (that is, the main body portion 10). At the center in the vehicle width direction). For example, as shown in FIGS. 2A and 2B, the striker positioning unit 30 is provided on the inner side in the vehicle width direction of the pair of support pieces 31, 31 opposed in the vehicle width direction and the pair of support pieces 31, 31. Resin pads 32, 32. By arranging the striker 7 between the pads 32, 32, the movement of the striker 7 in both directions in the vehicle width direction can be restricted, and the striker 7 and the glass hatch 4 can be positioned in the vehicle width direction. For this reason, it is preferable that the clearance in the vehicle width direction of the pads 32, 32 is substantially the same as the diameter of the metal rod forming the striker 7, and is set slightly wider than the diameter of the metal rod of the striker 7, for example. Alternatively, the striker 7 may be lightly pressed between the pads 32 and 32.

  The lock positioning portion 40 is for positioning the lock member 8 with respect to the vehicle body 1 in the vehicle width direction. The lock positioning part 40 is provided at the same position in the vehicle width direction as the striker positioning part 30, and in this embodiment, the center part P in the vehicle width direction of the pair of locking parts 20, 20 (that is, the center part in the vehicle width direction of the main body part 10). ). For example, as shown in FIGS. 2A and 2B, the lock positioning unit 40 includes a pair of support pieces 41 and 41 that face each other in the vehicle width direction. As shown in FIG. 2 (c), each support piece 41 is fixed to the main body 10 and extends downward from the main body 10 and forward from the lower end of the vertical portion 41a (FIG. 2 (c)). And a horizontal portion 41b extending to the right side of the head. The distance in the vehicle width direction of the horizontal portion 41b of the pair of support pieces 41, 41 is set to be substantially the same as the dimension in the vehicle width direction of the lock member 8, for example, slightly wider than the dimension in the vehicle width direction of the lock member 8. By disposing the lock member 8 between the horizontal portions 41b and 41b, the movement of the lock member 8 in both directions in the vehicle width direction can be restricted and the lock member 8 can be positioned with respect to the vehicle body 1 in the vehicle width direction. .

  The glass hatch placement portion 50 is for placing the lower end portion of the glass hatch 4 when the glass hatch 4 is assembled to the vehicle body 1. For example, as shown in FIG. 2A, the glass hatch mounting portion 50 includes a support plate 51 extending rearward from the main body portion 10 and a support member 52 provided on the upper surface of the support plate 51. The support member 52 is made of, for example, resin. A groove 53 is formed in the intermediate portion in the front-rear direction of the support member 52. The groove 53 is formed as shallow as possible with a depth that allows the groove 53 to engage with the lower end of the glass hatch 4 and be positioned in the front-rear direction. In the present embodiment, the groove 53 has a V-shape when viewed from the side in the vehicle width direction (see FIG. 2C), and is set to a depth of about 2 mm.

  The support portion 60 is for supporting an intermediate portion in the vehicle width direction of the long assembling jig 100. In the present embodiment, as shown in FIG. 2A, the pair of support portions 60 are fixed at positions symmetrical in the vehicle width direction with respect to the vehicle width direction center portion P of the main body portion 10. As shown in FIG. 2C, each support portion 60 is fixed to the lower surface of the main body portion 10 and extends downward, and forward from the lower end portion of the pillar portion 61 (right side in FIG. 2C). And a horizontal portion 62 extending in the horizontal direction.

  Next, a method for assembling the glass hatch 4 and the lock member 8 to the vehicle body 1 using the above assembly jig 100 will be described.

  First, the assembly jig 100 is attached to the vehicle body 1. Specifically, as shown in FIG. 3, the support portion 60 is placed on the lower end portion of the opening 3 of the vehicle body 1, and the protruding portion 22 of the locking portion 20 is inserted into the mounting hole 9 a of the combination lamp of the vehicle body 1. Insert and lock. At this time, the distance in the vehicle width direction of the pair of locking portions 20 and 20 is adjusted in accordance with the distance in the vehicle width direction of the mounting hole 9a of the vehicle body 1, and the pair of locking portions 20 is omitted by the centering mechanism 70 (not shown in FIG. 3). The vehicle width direction central portion P is set. Thereby, the vehicle width direction center part P of a pair of latching | locking parts 20 and 20 and the vehicle width direction center part (specifically the vehicle width direction center part of the attachment hole 9a of the vehicle body 1) correspond. To do. The striker positioning unit 30 and the lock positioning unit 40 are disposed at predetermined positions with respect to the vehicle width direction central portion P, and both are disposed on the vehicle width direction central portion P in the illustrated example.

  Next, the lock member 8 is disposed between the support pieces 41 of the lock positioning unit 40. Thereby, the lock member 8 is positioned in the vehicle width direction center part of the vehicle body 1 (see the chain line in FIGS. 3A and 3B). The lock member 8 thus positioned is fixed to the lower end of the opening 3 of the vehicle body 1.

  Then, as shown in FIG. 4, the lower end portion of the glass hatch 4 is placed on the glass hatch placement portion 50. Thereby, the glass hatch 4 is positioned with respect to the vehicle body 1 in the vertical direction. Further, the lower end portion of the glass hatch 4 is fitted into a groove portion 53 (see FIG. 2) formed in the support member 52 of the glass hatch mounting portion 50. Thereby, the lower end part of the glass hatch 4 is positioned in the front-back direction. Further, the width direction position of the glass hatch 4 with respect to the vehicle body 1 is adjusted so that the position in the width direction of the striker 7 and the striker positioning portion 30 coincides.

In this state, as shown in FIG. 5, the upper end portion of the glass hatch 4 is tilted forward. At this time, since the lower end portion of the glass hatch 4 is positioned in the front-rear direction by the groove portion 53 of the support member 52, the glass hatch 4 can be tilted in a stable state with the lower end portion of the glass hatch 4 as the center. By tilting the glass hatch 4 forward in this way, the striker 7 is inserted between the pads 32 and 32 (see FIG. 2) of the striker positioning portion 30, and the striker 7 and the glass hatch 4 are located at the center in the vehicle width direction of the vehicle body 1. Positioned. When the glass hatch 4 is further tilted, the upper end portion of the glass hatch 4 comes into contact with the hinge 5. In this state, the glass hatch 4 and a hinge 5 is fixed, glass hatch 4 is assembled to the vehicle body 1.

Thereafter, the glass hatch 4 is opened, and the glass hatch 4 is separated from the glass hatch mounting portion 50 of the assembling jig 100. At this time, since the shape and depth of the material and the groove portion 53 of the support member 52 that engages the lower end of the glass hatch 4 as described above is set as appropriate, to open the glass hatch 4 without hindrance it can. After opening the glass hatch 3, the assembling jig 100 is removed from the vehicle body 1, and the assembling work is completed.

  As described above, according to the assembling method using the assembling jig 100 of the present invention, the glass hatch 4 can be attached to the vehicle width direction central portion P of the vehicle body 1 only by mounting the striker 7 on the striker positioning portion 30. Simultaneously, the striker 7 and the lock member 8 can be aligned in the vehicle width direction. This eliminates the need to finely adjust the position of the striker 7 by plastically deforming the glass hatch 4 after assembling the glass hatch 4 to the vehicle body 1. The lid member can be suitably applied to those that cannot be finely adjusted by plastic deformation.

  By the way, if the glass hatch 4 is completely closed and the striker 7 and the lock member 8 are locked, the lock between the striker 7 and the lock member 8 is released when it is necessary to open the glass hatch 4 in the subsequent process. Trouble to do. Further, if the opening angle of the glass hatch 4 is too small, there is a possibility that the glass hatch 4 may come into contact with a weather strip (not shown) provided in the opening 3 when the glass hatch 4 is brought into contact with the hinge 5. In this case, the position of the glass hatch 4 becomes unstable due to the elastic force of the weather strip, and the positioning accuracy of the glass hatch 4 decreases. On the other hand, if the glass hatch 4 is opened too much (ie, close to the horizontal), it becomes difficult to place the glass hatch 4 on the glass hatch placement portion 50, and the striker 7 and the lock member 8 are too far apart. It is difficult to accurately position the. For the above reasons, it is preferable that the glass hatch 4 is positioned and attached in a state where the opening 3 of the vehicle body 1 is not completely closed but slightly opened as shown in FIG. Specifically, it is preferable to open the glass hatch 4 by about 5 to 10 ° from a completely closed state.

  For example, the opening angle of the glass hatch 4 can be reduced by providing the assembly jig 100 near the lower end of the opening 3 of the vehicle body 1. For example, as in the present embodiment, by using the rear combination lamp mounting hole 9a, the assembly jig 100 can be provided near the lower end of the opening 3 of the vehicle body 1 and at the same height as the rear combination lamp. Now, since the glass hatch 4 can be positioned in the vehicle width direction, it is possible to make the gap between the boundary portions that are particularly conspicuous uniform. Of course, it is possible to use two places other than the rear combination lamp mounting holes 9a that are symmetrical in the vehicle width direction of the vehicle body 1. However, in order to accurately set the vehicle width direction center portion of the vehicle body 1, it is preferable that the two locations be as far apart as possible, for example, it is preferable to use holes formed in the side members.

  The glass hatch 4 is not suitable for a high-temperature environment such as during drying of the painting process of the vehicle body 1 and therefore needs to be assembled to the vehicle body 1 in the assembly process after the painting process. In this case, since the glass hatch 4 is mounted in consideration of distortion generated in the vehicle body 1, for example, distortion due to drying heat in the painting process, or distortion due to assembly of other parts (instrument panel or the like), the assembly of the glass hatch 4 The accuracy is further increased.

  The present invention is not limited to the above embodiment. For example, although the case where the striker positioning part 30 is provided in the vehicle width direction center part of a pair of latching | locking part 20 is shown in said embodiment, it is not restricted to this. For example, when the striker 7 is provided by being offset in the vehicle width direction by a predetermined amount from the vehicle width direction center portion of the lid member (glass hatch 4), the striker positioning portion 30 is similarly the vehicle width of the pair of locking portions 20. What is necessary is just to provide offset by equal amount with respect to the direction center part. In this case, the lock positioning portion 40 is similarly provided at a position offset by an equal amount with respect to the center portion in the vehicle width direction of the pair of locking portions 20.

  Moreover, in said embodiment, although the striker 7 is mounted | worn with the striker positioning part 30 in the state which mounted the glass hatch 4 in the glass hatch mounting part 50, the procedure which positions the striker 7 is not restricted to this. . For example, the striker 7 may be attached to the striker positioning portion 30 after the upper end portion of the glass hatch 4 is temporarily fixed to the hinge 5 in a state where the position can be adjusted.

  In the above embodiment, the lock member 8 is positioned only in the vehicle width direction by the lock positioning portion 40. However, the present invention is not limited to this. For example, the lock member 8 may be positioned in the vehicle width direction and the front-rear direction. Good. Specifically, for example, in addition to the support pieces 41, 41, the lock positioning unit 40 may be provided with a clamp device (not shown) that clamps the lock member 8 from the front and rear and positions it at a predetermined position.

  In the above embodiment, the case where the lid member is a glass hatch is shown. However, the present invention is not limited thereto, and the present invention is applied even when the lid member is a hood assembled to the opening of the front portion of the vehicle body. Is possible. In this case, for example, an attachment hole of the front cowl can be used as the hole in which the pair of locking portions 20 and 20 are locked.

  In addition, the assembly jig 100 and the assembly method using the same according to the present invention are suitably applied to the assembly of glass or resin lid members as described above. It is also possible to apply to. Since the cover member made of sheet metal can withstand heat during drying in the painting process, the lid member can be assembled to the vehicle body 1 in a process prior to the painting process. In this case, it is preferable to set the attachment position of the lid member in consideration of the distortion generated in the vehicle body in the subsequent painting process and assembly process.
