BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a door locating apparatus for a vehicle, which is capable of accurately positioning a door to be mounted on a vehicle body at the time of building a door glass in a vehicle assembly line.

[0002]

2. Description of the Related Art In an automobile assembly line, when a door is mounted on a vehicle body, the door is positioned by a door positioning device. As shown in FIG. 3, the conventional door positioning device 10 includes an inner surface support plate 13 that supports the inner surface of the door B at an upper portion of the support frame 11 and a central portion in the vertical direction, and a door B at the lower portion of the door support frame 11. And a side positioning plate 15 for positioning a rear end B3 of the door B in the front-rear direction on one side of the support frame 11, and a door B on the other side of the support frame 11. Japanese Unexamined Utility Model Publication No. 2-115779 has a structure in which a pressing plate 17 for abutting against a front end B4 in the front-rear direction and pressing the rear end B3 of the door B against the side positioning plate 15 is provided so as to be able to advance and retreat by a cylinder 18. Provided.

[0003]

As shown in FIG. 4, when the conventional door positioning apparatus is positioned and mounted on a vehicle body with the door being held by the door positioning apparatus, it comes into contact with the front end B4 of the door B. Thus, there is a problem that the pressing plate 17 pressing the rear end B3 of the door B against the side positioning plate 15 interferes with the fender F, and the positioning operation cannot be obtained.

It is an object of the present invention to provide a vehicle door positioning apparatus which solves the above-mentioned conventional problems.

[0005]

SUMMARY OF THE INVENTION In order to achieve the above object, the gist of the present invention is to provide a suction pad to be sucked to a door outer panel , a door positioning member for supporting a lower end of a door in a vertical direction and a door inner and outer direction, and a door outer panel. A first frame suspended by a balance cylinder in the vertical axis direction, having a door clamper for gripping an upper edge of the door, and a rear side of the door
A door side positioning piece abutting on an end, and a door glass adjusting piece abutting on an upper edge and a rear edge of the door glass;
It comprises a second frame slidably supported by a frame in the front-rear direction of the door via a guide rail, and a second frame sliding cylinder disposed between the first frame and the second frame.

[0006]

With the above construction, the lower end of the door is supported by the door positioning members of the first frame in the vertical direction and the door inside and outside directions to position the door in the vertical direction and the door inside and outside directions, and the suction pad is sucked to the door outer panel. Next, the second frame is slid in the front-rear direction of the door by the cylinder to abut the door side positioning piece against the rear end of the door to complete the door positioning. At this position, the door glass adjusting piece is used to set the door glass. Attached.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to the drawings. 1 and 2, reference numeral 20 denotes a first frame. The first frame 20 includes a balance cylinder 27 in a vertical axis direction and a movable cylinder 26 which is guided on a guide rail 25 disposed in the direction of transport of the vehicle body on a ceiling or the like of an automobile assembly line so as to be able to travel. It is suspended via a fulcrum 36 which can swing in the direction.

The first frame 20 has a suction pad 21 which is attached to an outer panel 22a of the door 22,
2 and a door positioning member 23 for supporting the lower end of the door 2 in the vertical and door directions and a door clamper 24 for gripping the upper edge of the outer panel 22a. Reference numeral 24a is a clamping cylinder of the door clamper 24.

Further, a second frame 28 is supported on the first frame 20 via a guide rail 35 so as to be slidable in the front-rear direction of the door 22. The second frame 28 has a suction pad 29 that is sucked to the outer panel 22a of the door 22, a door side positioning piece 30 that is in contact with the rear end of the door 22, and a pair of left and right doors that are in contact with the upper edge of the door glass 22b. Glass adjustment piece 31 and door glass 22b
And a door glass adjustment piece 33 which comes into contact with the rear end of the door. Reference numeral 32 denotes a cylinder for operating the door glass adjusting piece 31.

A second frame sliding cylinder 34 is provided between the first frame 20 and the second frame 28.
Is arranged.

Since the present invention has the above-described structure, the lower end of the door 22 is supported by the positioning pieces 23 of the first frame 20 in the vertical direction of the door and the door inward and outward directions.
By clamping the upper edge of the outer panel 22a of the door 22, the door 22 is positioned in its vertical direction (H direction) and in and out of the door (W direction).

Next, the second frame 28 is slid in the front direction of the door 22 with respect to the first frame 20 by the second frame sliding cylinder 34 so as to position the door side positioning piece 3.
The door glass adjusting pieces 31 and 33 are positioned at a predetermined position in the front-rear direction (L direction) of the door 22 by abutting 0 on the rear end of the door 22. After the positioning of the door glass adjusting pieces 31, 33, the door glass adjusting piece 31 is brought into contact with the upper edge of the door glass 22b by the operating cylinder 31. The door glass adjustment piece 33 comes into contact with the rear end of the door glass 22b by sliding the second frame 28. This completes the door positioning when installing the door glass.

After the positioning of the door at the time of mounting the door glass is completed, the suction pad 21 of the first frame 20 and the suction pad 29 of the second frame 28 are moved forward by cylinders to be sucked on the outer panel 22a of the door 22, The positioning state of the door 22 is maintained, and the door 22 is attached to the vehicle body.

The first frame 20 and the second frame 2
When the door 22 positioned and supported by the position 8 is attached to the vehicle body, the moving body 26 travels along the guide rail 25 to follow the vehicle body that conveys the assembly line, and is balanced in the vertical direction by the balance cylinder 27 so as to move to the vehicle body. Assembled. At this time, since there is no door side positioning piece in front of the door 22 (the left end in FIG. 1), it does not interfere with the fender.

[0015]

As described above, according to the present invention, it is possible to position the door without restricting the front of the door, and therefore, it is possible to cope with a doorless process.
Another advantage is that the jig can be set at a rough position within the allowable range of the stroke of the second frame sliding cylinder when the jig is set on the door.
