Description

[Detailed description of the invention] (Industrial application field) The present invention relates to a method of assembling an automobile door.

(Prior Art) Conventionally, an automobile door generally consists of a door body made up of an inner panel and an outer panel, and door interior parts such as a window regulator assembled to the door body. In other words, in the conventional case, the inner panel and the outer panel are joined by hemming around the three sides excluding the waist line, so it is difficult to assemble the door interior parts to the door body. This is done by using the many working holes provided in the inner panel.

More specifically, in the door mounting process (the process of assembling the door interior parts to the door body) shown in Japanese Patent Publication No. 60-59101, no welding or pressing means is provided, so the inner A door body formed by joining a panel and an outer panel is transported to a door dispensing process, and door interior parts are assembled to the door body.

(Problems to be Solved by the Present Invention) For this reason, when using the conventional door assembly method, the door interior parts must be inserted into the working hole of the inner panel and positioned at a predetermined position during assembly work. Since the movement trajectory of the door interior parts is complicated, and the interior space of the door body is narrow, the workability of assembling the door interior parts is poor, and automation is also difficult. Ta.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a method for assembling an automobile door, which allows the door body to be assembled even during the door mounting process.

(Means and effects for solving the problem) In order to achieve the above technical problem, the present invention provides a means for joining an inner panel and an outer panel, such as a welding device or a press device, in the door delivery process. After overlapping and positioning an inner panel and an outer panel, each having a flange portion facing each other on the periphery thereof, a clamping member that clamps the flange portion is fitted to join the inner panel and the outer panel. That's what I do.

With such a configuration, it is possible to assemble the door interior parts before joining the inner panel and the outer panel. Moreover, by removing the clamping member that joins the inner panel and the outer panel, repair or replacement work of door interior parts can be performed with the outer panel removed.

Furthermore, compared to the case where an inner panel and an outer panel are joined using a port, work efficiency is improved because the effort of tightening the port can be saved.

(Example) Embodiments of the present invention will be described below based on the drawings.

Plan Tari” bottom! 11! In Fig. 1, reference numeral 1 denotes an automobile side door (hereinafter referred to as a door), and this door 1 is a sash door with a sash 2 at its upper part.The lower part of the door 1 is a skeleton 3 (second (see figure), inner panel 4 and outer panel 5 (third

Correspondingly, a screw hole 31 is formed in the side portion of the outer panel 5, as shown in FIG. This third
The figure shows the outer panel 5 viewed from the inside of the door. The port insertion hole 32 is formed to have a slightly larger diameter than the port 30, thereby absorbing molding errors between the inner panel 4 and the outer panel 5. Since the head of the port 30 is received by the metal spacer 33, loosening over time is prevented. On the other hand, flanges 36.37 extending in the front-rear direction are formed at the lower ends of the inner panel 4 and outer panel 5.

5 through a bell crank 27.

Mounting seat for the checker 13 The mounting seat 15 for the checker 13 provided on the end wall 6C of the front end member 6 is formed to be recessed inwardly, and the amount of the recess is determined by the amount of the recess when the inner panel 4 is assembled. At this time, the checker 13 in the state shown in FIG. 8 does not interfere with the inner panel 4.

That is, the checker 13, as shown in FIG.
The tip portion 13b is shaped to expand outward, and the main body 1
When the main body 13a is pulled in (the state shown in FIG. 8), the tip 13b prevents the main body 13a from falling out. For this reason, the inner panel 4 is assembled with the checker 13 in the state shown in FIG. 8. After the door 1 is mounted on the vehicle body, the checker body 13a is pulled out and the receiver attached to the pillar 73 is connected to the member 74 via a pin (not shown).

Door accessories Reference numeral 40 shown in FIG. 9 is an inside handle, and the inside handle 40 is composed of a handle body 41 and a frame 42, and is attached to the inside handle mounting seat 26 by a port 43. The inside handle 40 is assembled after the inner panel 4 is assembled.

The base end 41a of the handle body 41 is provided with a through hole 4 into which the inside handle connecting rod 25 is received.
4 is provided, and this through hole 44 is opened at the proximal end surface of the handle body 41, and this opening 45 is made slightly smaller than the outer diameter dimension of the connecting rod 25, so that the handle body 1 can be simply used as an inside handle. The conesting rod 25 is fitted into the through hole 44 simply by pressing against the conesting rod 25. - On the other hand, the distal end 25a of the connecting rod 25 is bent so as to be able to engage with the proximal end 41a of the nodle main body 41,
This prevents the connecting rod 25 from being pulled out.

Similarly, as shown in FIG. 10, the door lock knob 50 has a receiving groove 51 opened on its back surface 50a for receiving the rod 28 extending from the door lock component 16.
1 is formed in an L-shape, and its open end is partially made slightly smaller than the outer diameter of the rod 28. Correspondingly, the tip end 28a of the rod 28 is bent into an L-shape, as shown in FIG.
The connection between the rod 28 and the door lock knob 50 is achieved by simply pressing the door lock knob 50 against the rod 28.
This is done by fitting the tip end 28a of the two into the receiving groove 51, thereby facilitating the connection work of the two 50 and 28.

FIG. 12 shows an example of the assembly process for an assembly line vehicle. In this embodiment, the door building material is adjusted before entering the painting line, and this door building material adjustment is performed in a so-called spot matching manner. That is, in this embodiment, the door building materials are adjusted by adjusting the hinge 60 shown in FIG. The hinge 60 is fixed to the pillar 73 by positioning the hinge 60 with respect to the pillar 73 and tightening the pin 61.

Note that a collar 62 is provided between the hinge 60 and the skeleton 3.
This collar 62 is welded to the hinge 60 to prevent the fastening port 63 from loosening over time when the plastic inner panel 4 is interposed between the hinge 60 and the skeleton 3. Therefore, there is no problem in assembling the inch panel 4 in the door assembly process to be described later. Incidentally, FIG. 11 is a diagram showing the state in which the door 1 is finally mounted on the vehicle.

Temporary attachment of the outer panel The temporary attachment of the outer panel 5 in the above door building material adjustment is as follows:
As shown in FIG. 6, this is done by fitting two protrusions 65, 66 provided on the skeleton 3 at intervals in the front-rear direction with positioning holes 67, 68 provided on the outer panel 5.

Of these, the protrusion 65 and the positioning hole 67 are in a close fitting relationship. On the other hand, the other positioning hole 68 is an elongated hole extending in the front-rear direction, and the width (vertical dimension) of the elongated hole 68 is the same as the outer diameter dimension of the projection 66. As a result, both head fixing holes 67 and 68 and both protrusions 65.
The molding error relative to 66- is absorbed. The two positioning holes 67 and 68 provided in the outer panel 5 are covered with side protectors (not shown).

After the vehicle is painted on the door assembly process paint line, the skeleton 3
is removed from the vehicle body (as shown in Figure 13).
The skeleton 3 is removed from the hinge 60], and the vehicle body proceeds to the body 1 installation line, while the skeleton 3 proceeds to the door assembly line, where the door 1 is assembled.

The door 1 is assembled in the step shown in FIG. 14. In this door assembly step, the upper stay 8 and the lower stay 9 are pre-assembled with the wind guide 20 (as shown in FIG. 13). is marked as an I-type bracket),
After the window regulator 19 and the like are assembled to this type 1 bracket, the front end member 6 and rear end member 7 are assembled (see FIG. 4).

Door interior parts such as the glass launch channel 70 shown in FIG. 4 are installed before the inner panel 4 and outer panel 5 are assembled, and the window glass 23 is installed before the front end member 6. This is done by inserting the members 6.7 into the space sandwiched between the rear end members 7 from below. This results in
The ease of assembling the window glass 23 is improved.

After the door interior parts are assembled to the skeleton 3 in this way, the inner panel 4 is first attached to the skeleton 3.
It is assembled against. The assembly of the inch panel 4 is carried out after first applying an adhesive 80 to the entire skeleton 3 in the height direction, as shown in FIG. and skeleton 3 are glued together. After that, the outer panel 5 is attached to the inch panel 4 using the port 30 and the clip 85.
It is joined with.

That is, the outer panel 5 is first positioned with the inner panel 4 by fitting the projections 38 and the positioning holes 39 into protrusions, and then the long clips 85 are inserted from one end of the flanges 37.38. Then, it is fitted into the flanges 37 and 38 (see FIG. 14), and the port 30 is tightened.

In this way, when assembling the door interior parts, the inner panel 4,
Since the work is carried out on the skeleton 3 before the outer panel 5 is assembled, the work space is not limited by the presence of the inner panel 4 and the outer panel 5. Therefore, when assembling door interior parts, the inner panel 4.
The work can proceed without being bothered by the presence of the outer panel 5, the work efficiency can be improved, and automation is also possible.

Moreover, since the inner panel 4 and the outer panel 5 are joined using the clips 85, the number of ports 30 can be reduced, and the effort of tightening the ports can be reduced.

Furthermore, since the outer panel 5 is removable using the clips 85 and ports 30, after the door 1 is mounted on the vehicle, the outer panel 5 can be removed to free up a work space for repairing or replacing door interior parts. It becomes possible to increase the size and improve serviceability.

Although one embodiment of the present invention has been described above, the present invention is not limited to this and includes the following modifications.

(The p-door 1 may be a stainless steel door.

(The inner panel 4 and the outer panel 5 may be made of steel plates.

0) All three sides of the inner panel 4 and outer panel 5 except for the waist line may be clipped.

(2) The clip 85 may be short, and the inner panel 4 and the outer panel 5 may be joined using a plurality of clips.

(Effects of the Invention) As explained above, according to the present invention, the door body can be assembled in one installation process, so the door interior parts can be assembled before the inner panel and outer panel are assembled. Assembling work efficiency can be improved and automation thereof possible. Further, since the outer panel is detachable from the inch panel, it is possible to take up a large work space for repairing door interior parts, etc., and serviceability can be improved. Further, compared to the case where the outer panel and the inner panel are joined using a port, the workability is improved because the joining between the two can be achieved simply by fitting the clamping member.
