Abstract

A vehicle assembling apparatus including a part transfer arm supported at one end for swingable movements about vertical and horizontal axes, a part carrying plate provided at the other end of the transfer arm for carrying a part to be assembled, and a fastener driving tool for driving fasteners. The fastener driving tool is supported on the part carrying plate for swinging movements about a vertical axis and for adjustment of the distance between the part carrying plate and the fastener driving tool.

Claims

1. A vehicle assembling apparatus including part transfer arm means supported at one end for swingable movements about a vertical axis and a horizontal axis, part carrying means provided at the other end of the transfer arm means for carrying a part to be assembled, fastener driving means for driving fasteners, support means for supporting the fastener driving means on said part carrying means for swinging movements about a vertical axis and for adjustment of the distance between the part carrying means and the fastener driving means, said support means including a swingable arm mounted on the part carrying means for swingable movements about a vertical axis with respect to the part carrying means, the fastener driving means being slidably supported on the swingable arm for movement along the swingable arm, and position adjusting means for adjusting the position of the fastener driving means on the swingable arm.

2. A vehicle assembling apparatus in accordance with claim 1 in which said part transfer arm means is mounted at said one end on a rotatable support which is provided on a transfer table movable in a direction perpendicular to a direction in which assembled parts are to be transported.

3. A vehicle assembling apparatus in accordance with claim 1 in which said part carrying means is mounted on the other end of the transfer arm means for swingable movements about a horizontal axis.

4. A vehicle assembling apparatus in accordance with claim 1 in which said position adjusting means includes screw means extending in parallel with the swingable arm, nut means provided on said fastener driving means and engaged with said screw means, and motor means for driving the screw means.

5. A vehicle assembling apparatus in accordance with claim 1 in which said fastener driving means includes fastener feeding means for automatically feeding fasteners to the fastener driving means.

6. A vehicle assembling apparatus in accordance with claim 1 in which said part carrying means in provided with rotating means for rotating said part carrying means on the transfer arm means.

7. A vehicle assembling apparatus in accordance with claim 1 in which said part carrying means is provided on a vertical shaft rotatable on a housing which is mounted on said other end of the transfer arm means, and motor means for rotating said vertical shaft.

8. A vehicle assembling apparatus in accordance with claim 7 in which said support means includes a vertical shaft carried by said part carrying means, said swingable arm means connected to said vertical shaft for swinging movements about said vertical axis, and second motor means for effecting a swinging movement of said swingable arm means, said fastener driving means being supported on said swingable arm means slidably along said swingable arm means.
