Description

The present invention relates to assembly of a front-opening rear door of a vehicle.

Generally, in the case of a rear-opening rear door, even if the door is held by a material hand and the door is placed in a closed position covering the vehicle body opening, the hinge mounting portion of the center pillar of the vehicle body is exposed. Even if the front door is assembled first, if the front door is opened, the hinge of the rear door in the closed posture is exposed. Therefore, the rear-opening rear door can be assembled to the vehicle body in a closed position (Patent Document 1).

JP 2010-208526 A

On the other hand, in the case of a front-opening rear door, the hinge mounting portion is provided on the pillar at the front end of the rear fender, and when the rear door is closed, the hinge mounting portion is hidden behind the rear door and cannot be seen. Therefore, when assembling the front-opening rear side door to the vehicle body, it is necessary to open the rear side door so that the hinge mounting portion of the pillar is exposed.

When the door is in the closed position, it is easy to determine the position of the door relative to the vehicle body in the longitudinal direction and the vertical direction of the vehicle body by looking at the gap between the door and the periphery of the opening of the vehicle body. However, when the door is in the open position, the gap between the opening and the periphery of the vehicle body cannot be seen, making it difficult to position the vehicle body in the longitudinal direction.

Positioning of the door in the open position can be done indirectly by grasping the inner side of the door with a material handle, determining the position of the inner side, and then positioning the material handle with respect to the vehicle body. . However, since the positioning is performed on the inner side, which has weak rigidity, the positioning accuracy tends to be low. It is easy to become displaced in the front-rear direction.

In addition, when the hinge attached to the door is screwed to the vehicle body, the hinge is prevented from being subjected to tightening torque and corotating. It is also necessary to prevent the occurrence of

<Vehicle door assembly method>
An assembling procedure for assembling the vehicle door 2 to the vehicle body 1 will be described.

FIG. 10 shows the material handling jig 3 holding the vehicle door 2 and the vehicle body 1 . The material handling jig 3 grips the vehicle door 2 as described above. The vehicle door 2 held by the material handling jig 3 is conveyed to the opening 12 of the vehicle body 1 by the operation of the working robot, and positioned in the opening 12 in an open posture. A cylinder pressure that offsets the loads of the vehicle door 2 and the door holder 31 is applied to the floating cylinder 4 , and the vehicle door 2 and the door holder 31 are held floating on the frame 32 . In this state, the body reference pin 313 of the material handling jig 3 is inserted into the body reference hole 14 of the vehicle body 1 . Due to the floating holding, the door holder 31 slides up and down on the slide rail 6 to absorb variations in vehicle body position, and the vehicle door 2 is positioned on the vehicle body 1 . After this positioning, the vehicle body 1 is clamped by the body clamp device 323 of the material handling jig 3, and the positions of the vehicle body 1 and the material handling jig 3 are fixed as shown in FIG.

The vehicle door 2 held by the material handling jig 3 has its hinge 21 clamped by the hinge clamp device 5 . A fixed abutment member 52 and a movable abutment member 53 of the hinge clamp device 5 are brought into contact with the vertical plate portion 215 of the vehicle body side hinge member 212 of the hinge 21 from the longitudinal direction of the vehicle body. As a result, the position of the hinge 21 in the longitudinal direction of the vehicle body is regulated.

The vehicle door 2 positioned in the open position with respect to the vehicle body 1 via the material handling jig 3 has the hinge 21 screwed to the hinge fastening portion 13 of the vehicle body 1 from the outside of the vehicle body. This is done by screwing the fixed plate portion 214 of the vehicle body side hinge member 212 of the hinge 21 to the surface of the vehicle body 1 facing outward in the vehicle width direction. As a result, the vehicle door 2 is assembled to the vehicle body 1 .

Tightening torque is generated when screwing. Rotation regulation for regulating rotation of the hinge 21 due to this tightening torque is performed by clamping the vertical plate portion 215 from the longitudinal direction of the vehicle body with the fixed abutment member 52 and the movable abutment member 53 of the hinge clamp device 5 . .

<Effects of material handling equipment>
Therefore, in the above-described embodiment, the vehicle door 2 has high rigidity, and the position of the hinge 21 attached to the vehicle body 1 in the front-rear direction of the vehicle body is regulated. That is, since the hinge 21 serves as a positioning reference in the longitudinal direction of the vehicle body, it becomes easy to ensure the positioning accuracy in the longitudinal direction. Further, by restricting the rotation of the hinge 21 when screwing the hinge 21 to the vehicle body 1, deformation of the hinge mounting portion 23 of the vehicle door 2 and displacement of the vehicle door 2 due to tightening torque can be avoided. Therefore, even when the vehicle door 2 is assembled to the vehicle body 1 in the open position, the vehicle door 2 can be assembled to the vehicle body with high positional accuracy. That is, when the vehicle door 2 is closed, the vehicle door 2 is prevented from being displaced with respect to the vehicle body 1 .
