Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to an applied vehicle type vehicle in which a diffused warning light is mounted on a roof panel, such as an ambulance or a patrol car, or a normal vehicle in which an indoor light is mounted. The present invention relates to an improvement in a method of fixing a bracket for mounting a warning light, an interior light, or the like.

[Conventional technology]

In an applied vehicle type vehicle in which a diffused warning light or the like is mounted on a roof panel or a normal vehicle in which a room light is mounted, a bracket for mounting the warning light or the room light or the like must be mounted on an outer surface or an inner surface of the roof panel.

In the prior art, this bracket is fixed by using a thermosetting adhesive or by spot welding with the welding gun and the pedestal arranged from above and below the roof panel.

[Problems to be solved by the invention]

However, since the welding gun does not reach the bracket mounting position on the roof panel of the vehicle, a special spot welding machine is required, and since the thermosetting adhesive must apply heat to the bracket bonding part, a special heating means is required. Need and
Therefore, in each case, the equipment was large and uneconomical.

Further, since it takes a long time to attach the bracket, the subsequent processing cannot be performed continuously, so that there is a disadvantage in that the assembling time of the vehicle is lengthened.

For this reason, it is conceivable to temporarily fix the bracket to the roof panel with a magnet temporary fixing jig so that post-processing can be continued even if the bracket is not completely fixed. Prior art temporary fixing methods used in various fields for temporarily fixing a component to be mounted are generally designed to press the entire mounting component with the force of a magnet. When special jigs to be combined with magnets are required, equipment becomes large, especially when the mounting surface is not planar, and if you try to temporarily fix the entire bracket to the roof panel of a car with a curved surface or uneven surface, There is a disadvantage that the equipment becomes complicated.

Furthermore, when the entire bracket is temporarily fixed with a temporary fixing jig made of magnet, the temporary fixing jig straddles the entire bracket and the roof panel in order to prevent the bracket from being displaced within the temporary fixing jig. Therefore, it is extremely difficult to prevent a bracket as an attachment component from being displaced during the temporary fixing by a temporary fixing jig having a simple shape.

SUMMARY OF THE INVENTION An object of the present invention is to provide a method of bonding a bracket to a roof panel of a vehicle, which can avoid the above-mentioned drawbacks and can securely fix the bracket with small and simple equipment.

[Means for solving the problem]

The solution of the present invention is a method in which an adhesive is applied to a mounting surface of a flange of a flanged bracket for attaching various devices to a roof panel of a vehicle, and the adhesive of the flange of the bracket is applied to the roof panel and bonded. The roof panel is made of a magnetic material, and a magnet temporary fixing jig having an engaging surface corresponding to a shape that straddles the bracket flange and the roof panel is prepared. A temporary fixing jig is sucked and attached to the roof panel with the flange of the bracket sandwiched between the brackets so that the flange of the bracket is pressed against the roof panel by straddling the engaging surface and temporarily fixing after the adhesive is cured. It is an object of the present invention to provide a method of bonding a bracket to a roof panel of a vehicle, which comprises removing a jig.

In this case, the bracket may be made of any of a magnetic material and a non-magnetic material. However, if it is made of a magnetic material, it is advantageous because the adhesive strength can be confirmed as described later.

[Action]

As described above, when a temporary fixing jig made of magnet is used with the bracket having the flange to which the adhesive is applied so that the adhesive is applied to the roof panel, the adhesive is hardened by the temporary fixing jig. Since the bracket is positioned at a predetermined position on the roof panel, the subsequent processing can be continued, so that the operation can be performed economically.

In particular, this temporary fixing jig made of magnets has not only the entire bracket as a mounting part, but only an engaging surface of a simple shape corresponding to a shape straddling a flange thereof and a roof panel as a member to be mounted. Therefore, the bracket can be temporarily fixed with a temporary fixing jig having a simple shape without displacement.

When the bracket is made of a magnetic material, the temporary fixing jig can be removed against the adhesive strength of the bracket, so that the adhesive strength of the bracket can be confirmed.

〔Example〕

Embodiments of the present invention will be described in detail with reference to the drawings.
FIG. 1 shows a vehicle roof panel 12 to which a bracket 10 is fixed by the method of the present invention. In this embodiment, the bracket 10 is fixed to the outer surface of the roof panel 12 for the purpose of mounting a diffused warning light, for example. It is shown.

In fixing the bracket 10 to the outer surface of the roof panel 12 as described above, first, as shown in FIG. 2, an adhesive 14 is applied to the mounting surface of the bracket 10 on the flange 10a. The adhesive 14 may be a thermosetting adhesive or a two-component mixed-temperature-setting adhesive.

Next, the flange 10a of the bracket 10 is pressed so that the bracket 10 is pressed against the roof panel 12 while the adhesive 14 of the flange 10a of the bracket 10 is applied to the outer surface of the roof panel 12.
A temporary fixing jig 16 made of magnet is provided on the outer surface of the roof panel 12 with the
And attach it. The temporary fixing jig 16 has an engaging surface 16a corresponding to a shape straddling the flange 10a of the bracket 10 and the roof panel 12. Therefore, the temporary fixing jig 16 is
The flange 10a of the bracket 10 can be temporarily fixed and the position of the bracket 10 can be reliably prevented by merely engaging the brim 10a of the bracket 10 and the roof panel 12 by straddling the flange 6a with 6a. The roof panel portion with which the engaging surface 16a of the temporary fixing jig 16 is engaged is a portion around the flange 10a of the bracket 10, and this roof panel portion is necessary for securing the temporary fixing and displacement. It is set to an appropriate size (area). In this case, it goes without saying that the roof panel 12 must be made of a magnetic material in order to suck the temporary fixing jig 16.

In this manner, the bracket 10 is fixed to the temporary fixing jig 16.
Thus, the roof panel 12 is fixed to a predetermined position on the roof panel 12 and does not shift even when the roof panel 12 is transported together with the bracket 10 to a post-processing step.

After the adhesive 14 has hardened, the temporary fixing jig 16 is removed,
Since the bracket 10 is fixed to the roof panel 12 by the hardened adhesive 14, it does not come off.

The thermosetting adhesive 14 is suitable for use in attaching the bracket 10 to the roof panel 12 before painting. In this case, while the bracket 10 is fixed to the roof panel 12 with the temporary fixing jig 16, the roof panel 12 is carried to the painting process, and after the coating, the coating is dried and the thermosetting adhesive is simultaneously cured in the drying furnace. Can be.

Even when the room-temperature-curable adhesive 14 such as a two-component mixture type is used, the roof panel 12 can be processed in an appropriate subsequent processing step because the bracket 10 is fixed by the temporary fixing jig 16.

Of course, after painting the roof panel 12,

When the bracket 10 is fixed after the roof panel 12 is painted, a temporary fixing jig 16 having a protective coating 18 shown in FIG. 4 can be used. In the embodiment shown in FIG. 3, the roof panel 12 must of course be made of a magnetic material.

In the embodiment shown in FIGS. 2 and 3, the bracket 10 may be made of either a magnetic material or a non-magnetic material.
Must be removed against the strength with which the bracket 10 is glued to the roof panel 12,
It is preferable because the adhesive strength of 10 can be confirmed.

〔The invention's effect〕

According to the present invention, as described above, the bracket is pressed against the roof panel with the magnet temporary fixing jig while applying the adhesive of the flange of the bracket to the roof panel. Since it is positioned at a predetermined position on the roof panel until it is cured, the subsequent processing of the roof panel can be continued, the operation can be performed easily and economically, and the temporary fixing jig is made of a magnetic material. If the bracket is directly engaged, there is a benefit that the adhesive strength of the bracket can be checked when the temporary fixing jig is removed.

In particular, the magnet temporary fixing jig has not only the entire bracket which is the mounting part, but only an engaging surface having a simple shape corresponding to the shape straddling the flange and the roof panel which is the mounted member. As a result, the bracket can be temporarily fixed with a simple shape of the temporary fixing jig without displacement.
