Abstract
An automobile door is mounted in a body structure via generally vertically spaced first and second hinges. The door is initially placed so as to be opposed to a door opening formed in the body structure, and at least one of the bolts for tightening the first hinge is provisionally tightened more tightly than any other bolts. Thereafter, the door is rotated about the more tightly pre-tightened bolt for proper positioning of the door. Finally, all the bolts are completely tightened.
Claims9
A method of accurately positioning an automobile door with respect to an automobile body structure preparatory to fixedly mounting said door to said body structure, said method comprising:
- placing said door in a location opposed to a door opening in said body structure;
- determining a vertical position of said door by detecting by an image-processing operation a vertical position of a reference point on said door;
- determining the existence of any errors of said detected vertical position of said reference point due to a relative opened position of said door at said location by detecting at least one parameter of an area of said reference point at said location of said door and a distance in a direction longitudinally of said body structure between a center of said reference point at said location of said door and said center of said reference point at a closed position of said door;
- determining a corrected vertical position of said reference point based on the thus detected said at least one parameter;
- and
- moving said door relative to said body structure from said location by a distance based on the thus determined said corrected vertical position.
