Abstract

A method for positioning a pair of door hinges on a vehicle body can include the sequential steps of placing the hinges on locator pins carried by a portable fixture, advancing the fixture against the vehicle body so that multiple pegs on the fixture enter into preformed locator holes on the vehicle body, and clamping the fixture in position by automatic mechanisms responsive to entry of the pegs into the locator holes.

Claims

1. A method for positioning a pair of hinges on a vehicle body adjacent to a vehicle door opening, said method including:

(a) placing the hinges on locator pins that extend from a hinge positioner fixture;

(b) locking the door sections of the hinges to the locator pins;

(c) advancing the fixture against the vehicle body so that multiple pegs on the fixture extend into locator holes on the body;

(d) clamping the fixture to the vehicle body;

(e) fastening the body sections of the hinges to the vehicle body;

(f) releasing the door sections of the hinges from the locator pins;

(g) unclamping the fixture from the vehicle body; and

(h) separating the fixture from the vehicle body;

wherein steps (a) through (h) are performed while the vehicle body is being moved along a predetermined path by a conveyor;

and steps (a), (c), (e) and (h) are performed by a human technician located on a platform that is moving at the same speed as the aforementioned conveyor;

and step (d) is controlled automatically by proximity switches that respond to insertional movements of the pegs into the locator holes on the vehicle body;

and steps (f) and (g) are accomplished sequentially by an automatic timer.

2. The method of claim 1, wherein step (b) is performed by manually energizing power actuators for yoke structures that are movable to lock the hinges to the locator pins.

3. The method of claim 1, wherein step (f) is performed by manually energizing power actuators for yoke structures that are retractable from the hinges.

4. The method of claim 3, wherein step (f) further includes retracting the hinge locator pins away from the door sections of the hinges.

5. The method of claim 1, wherein step (h) includes simultaneously advancing plural push pins from the hinge positioner fixture onto the vehicle body so that said pegs are forced out of the locator holes on the vehicle body.

6. The method of claim 1, and further including the step of changing the spacing between said pegs prior to step (c), wherein said pegs are mounted on turntables that are rotated to present different pegs to the locator holes on different style vehicle bodies.
