Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a set structure for a vehicle body, and the set referred to herein refers to a temporary fixing set before joining the panels constituting the vehicle body.

Conventionally, the set structure of a roof front portion and a front pillar is generally as shown in FIGS. 1 to 5. That is, a channel-shaped roof extends in the vehicle width direction along a roof panel (not shown).

At the joint between the roof rail 1 and the inner panel 20 of the front pillar 2 extending in the vehicle height direction, as shown in FIG. A roof rail 1 which is press-formed to extend and is formed into a channel shape on the other hand.
A square hole 12 is formed at a position corresponding to the cut-and-raised piece 24 at one end of the side. When setting the front roof rail 1 and the pillar inner panel 20, insert the cut-and-raised piece 24 into the square hole 12 as shown in FIG. 3, and as shown in FIG. The side weaving part 10 of the front roof rail 1 and the upper end part 22 of the pillar inner panel 20 on the roof panel side are overlapped so that they match, and then, as shown in FIG. The set is completed by bending and preventing the front roof rail 1 from coming off, and then the welding process begins. However, since the above-mentioned set requires manual hammering work, the number of man-hours increases, and the hammering work posture is also poor, resulting in unfavorable working conditions.

The present invention has been made in view of the above-mentioned conventional situation, and has a set structure in which the ends of panels formed in a channel shape are temporarily fixed and polymerized together, and the separation and positional shift of the panels can be easily and efficiently performed. It is designed to prevent this.

Hereinafter, the present invention will be explained based on the embodiments shown in the drawings, with the same reference numerals assigned to parts that are completely the same as those of the prior art.

In Figures 6 to 10, the front roof rail 1
In the set structure of the front pillar 2 and the biller inner panel 20, the pillar inner panel 20 is formed in a channel shape as shown in FIGS. roof panel side end 22
It has a wisteria line along the longitudinal direction of the channel as shown in Fig. 9 and Fig. 10, and the green at both ends 202, 204 corresponds to one side of the vehicle width direction (X direction) in the longitudinal direction of the channel, that is, the center part of the roof panel. Hook 2 with side bevel (posterior bevel a,)
00, and a square hole 12 is formed at a position corresponding to the hook 200 in the side end 10 of the front roof rail 1 located on the upper side in the overlapping plane.

This front roof rail 1 and pillar inner panel 2
0, first the car body floor main assembly (not shown) is set, then the body side assembly including the front pillar 2 is set on the floor main assembly, and the key points are welded. do. After that, the front roof rail 1 is attached to the pillar inner panel 20.
However, the setting of the front roof rail 1 onto the pillar inner panel 20 is related to the present invention, and the front roof rail 1 is lowered from above toward the hook 200, and then The square holes 12 are polymerized as shown in FIGS. 9 and 10. The hook 200 is curved by cutting out a corner part 206 at the upper part of the edge 202 so that the hook 200 can easily enter the square hole 12 when the front roof rail 1 is stacked. By the way, as a characteristic of car body assembly, there is a tendency for the body side side to become wider in the car width direction and the forehead to be narrower.
In the case shown in the figure, it can be adapted to cases where the body side becomes narrower.

As an example that is suitable when the body side becomes wider, the first
As shown in FIG.
is inclined (inclined angle 02) toward the other side of the vehicle width direction (XX direction), which is the channel longitudinal direction, that is, the pillar inner panel main body side. Also, front roof rail 1
When the pillar inner panel 20 is overlaid, as shown in FIG.
That is, it has a channel shape that prevents positional displacement in the Y-Y direction. With this configuration, by simply laying the front roof rail 1 on the pillar inner panel 20, positioning in the vehicle longitudinal direction Y-Y can be performed only by overlapping the channels, so misalignment can be prevented, and positioning in the vehicle height direction, i.e. Figure 10 Positioning in the Z-Z direction can be maintained by the weight of the front roof rail, and positioning in the vehicle width direction (x direction) can be maintained using the hook 200.
This can be prevented by engaging the square hole 12 with the square hole 12.

Especially when the body side is facing toward the narrower side, it is formed as shown in FIG. 9, so that if the position is about to shift, the front edge 202 of the hook 200 and the circumferential green 120 of the square hole 12 will come into contact. to prevent misalignment,
If the body side is widened, the end edge 20 of the hook 200 should be formed as shown in FIG.
4 and the surrounding green 120 of the square hole 12 come into contact with each other to prevent positional displacement. Therefore, after the front roof rail 1 is placed on the pillar inner panel 20, there is no need to manually hammer the front roof rail 1 as required in the past. Setting can be easily completed without causing positional deviation, and setting work efficiency is significantly improved.

In addition, when positioning the front roof rail 1 and pillar inner panel 20 in the correct position when set,
As shown in FIG. 6, it is also possible to maintain the regular relational dimensions from the 30 rivers. The set structure of the front roof rail 1 and the pillar inner panel 20 has been explained above, but it can also be applied to the set structure of the rear roof rail and the pillar inner panel by overlapping the ends of the channel-shaped panels. The same can be applied to any structure in which the method is set.
