Description
~LZ48;~3~
This invention relates -to an apparatus for fastening a door for a vehicle of the type wherein a door hinge of a door inserted in a door opening portion of a vehicle body may be bol-ted to the vehicle body by a nut runner provided on a fastening head movable -to advance and retreat in relation to the vehicle body.
It has been usual hitherto wi-th this kind of fastening apparatus to provide on a forward end por-tion of a fastening head an opening and closing jaw means for holding a bolt supplied from a parts feeder, so that by advancing a nut runner through the interior of the jaw means, -the bolt can be brought into engagemen-t with the nut runner to enable the door hinge to be bolted.
This apparatus, however, is disadvantageous in that the fastening head becomes larger in diameter a-t its forward end por-tion due to the existence of the jaw means, and consequently it is necessary to provide a comparatively large clearance for allow-ing the jaw means to pass there-through between an end edge of the door and the part to which the door hinge is to be bolted. The degree of freedom in designing the vehicle body is -therefore restricted.
An object of the invention is to provide a fastening apparatus which is free from the foregoing disadvantage.
According to the present invention there is provided an apparatus for fastening a door of a vehicle f the type where in a door hinge of a door inserted in a door opening of the vehicle body is bolted to the vehicle body by a nut runner provided on a fastening head which is movable to advance and retreat in rela-tion to the vehicle bOdyr sa~d apparatus comprising bolt receiving and supplying means comprising a bolt supplying head connected to a parts feeder and a bolt transfer head provided on a side of the fas-tening head, said transfer head being movable ~ 1 --~Z9~833~
between a bolt-receiving position facing the supplying head and a bolt-delivering posi-tion facing the fastening head so tha-t a bolt supplied through the supplying head may be set on the nut runner through the transfer head.
In such an apparatus the bolt can be set on a nut runner through a bolt-receiving and supplying means provided separately from the nut runner, while -the use of the ~aw means is abolished, result-ing in the fact that it is applicable also to the case where the clearance between an end edge of a door and a portion to which a door hinge is to be bolted is comparatively narrow.
The invention will now be described in more detail, by way of example ony, with reference to the accompanying draw-ings, in which:-Fig. 1 is a top plan view of a vehicle door assemblyapparatus provided with one embodiment of the invention;

the elevating frame 6c as to extend long in the vehicle width direction.
If such an arrangemen-t is supported so that the res-pective fastening heads 3, 3' are provided on their forward end portions with jaw means for receiving the respective nut runners so that bolts may be supplied thereto direc-tly from a par-ts feeder, especially when -the gap between the front end edge of the rear door c and the part to which -the door hinge _ is to be bolted is narrowed, as shown in Fig. 8, in view of the rela-tion of the rear door c with the width of the center pillar or -the like, it can often happen that the jaw means becomes a hindrance and thereby the desired bolting cannot be carried out.
Accordingly, in the illustrated example, a bolt-receiv-ing and supplying means 9 is so provided on the machine frame 7 as to be located in front of the fastening heads 3, 3' so that bolts supplied from a parts feeder (not illustrated) can be set on the respective nut runners 3a, 3'a through the foregoing means 9, and the desired bolting may be carried out reliably, without using the jaw means, even when the foregoing clearance 1 is nar-rowed to that corresponding to the radius of the nut runner 3aitself.
The bolt receiving and supplying means 9 comprises a bolt supplying head 10 which is to be conected to a parts feeder and a bol-t transferring head 11, and the supplying head 10 is fixedly provided on the machine frame 7 and the transferring head 11 is a-ttached to a slide frame 12 provided on the machine frame 7 so that, by an operation of a driving cylinder 12a Eor the slide frame 12, the transferring head 11 may be moved reciprocally between its frontward bolt receiving position facing the supply-ing head 10 and its rearward delivering position facing the fore-going fastening head 3,3'. Additionally, as shown in Figs. 5 and - 6, the supplying head 10 is so provided with a plurality of bolt , .
~24~1333~
supplying openings lOa for being connected to bolt pressure feeding tubes 13 connected to a parts feeder, that the bolt supply-ing openings lOa, lOa may be disposed in accordance with the dis-position of the nut runners 3a, 3a of the respective fastening heads 3, 3'. The transfer head 11 is also provided, in the similar manner as above, with a plurality of bol-t receiving openings lla for receiving bolts supplied through the supplying openings lOa. In addition, each receiving opening lla is provided with a clamp cylinder llb for firmly holding the bol-t inserted therein, and an air introducing opening llc for both cleaning the bolt-receiving opening lla and pushing-out the bolt.
Next, the operation of the foregoing example will be explained as follows:-Prior to introducing the rear door c to the set jig 2,a bolt e is set, through the bolt-receiving and supplying means 9, to each of the nut runners 3a, 3'a of the two fastening heads 3, 3' for the rear door and the fron-t door, respectively.
In more detail, each bolt receiving opening lla of the bolt transfer head 11 is supplied, through each bolt supplying opening lOa of the bolt supplying head 10, with a bolt e from the parts feeder. The transfer head 11 is then moved to the bolt-delivering positian under the condition that each bolt e is fixed in the corresponding receiving opening lla by the operation of each clamp cylinder llb. The two fastening heads 3, 3' are then slightly advanced towards the transfer head 11, and each of the nut runners 3a, 3'a is inserted in each receiving opening lla while being rotated. The head of each bolt e is thereby brought into engagement with the foreward end socket por-tion thereof.
After the engagement thereof, each clamp cylinder llb is released from its holding operation, and at the same time the two fasten-ing heads 3, 3' are withdrawn, whereby each bolt e is drawn out from each ~eceiving opening lla under the condition that the same ,.
.

is attracted by each magnet 3d, 3'd pxovided on each nu-t runner 3a, 3'a.
Tnereaf-ter, the respec-tive fastening heads 3, 3' are operated as mentioned above so as to effect-the bolting of-the door hinge d of-the rear door c and the bolting of the door hinge d' of the front door c' In an al-ternative case where, instead oE assembling -the rear door and the fron-t door by the single common set jig 2 as in the foregoing example with -the vehicle body, the rear door and the front door are intended -to be assembled by their individual set jigs mounted on individual robot mechanisms, the fastening head for the rear door and the fastening head for the front door are mounted individually on respective robot mechanisms provided in parallel with the foregoing robot mechanisms. In this case, the bolt-receiving and supplying means 9 for the rear door and that for the front door are provided separately one from another.
The bolt-receiving and supplying means is thus provided on one side of the fastening means so that a bolt supplied from a parts feeder may be set on the nut runner provided on the fas-tening head by way of the bolt transfer head provided on the bolt-receiving and supplying means. Thus, it is no-t necessary for ~0 the fastening head to be provided with a jaw means for holding a bolt supplied ~from a parts feeders, and the bolting can be carried ou-t reliably even if the gap between an end edge of a door and a part to which a door hinge is to be bolted is narrow, so long as there exlsts the in-terval for allowing the nut runner to pass therethrough. Thus, the degree of freedorn in vehicle design can be increased.
This invention relates -to an apparatus for fastening a door for a vehicle of the type wherein a door hinge of a door inserted in a door opening portion of a vehicle body may be bol-ted to the vehicle body by a nut runner provided on a fastening head movable -to advance and retreat in relation to the vehicle body.
