ABSTRACT:
In a correcting method of an automobile's door frame by applying a conventional correcting unit, tightening method to securely fix hinges of the door frame by means of jigs is developed, as well as clampers, and the door frame is supported by three points such as two hinges and a damper as if in the same manner as the door frame is supported by two hinges and a door lock in actual installation in a car when the door frame is inspected. The door frame is also slightly touched by a floating unit on an upper corner of reaward edge of the door frame when the door frame is corrected, preventing a slight distortion generated during the correcting operation from being unfairly enlarged. 12 patterns combinations of parameters and 20 correcting approximate equations are prepared. Aforementioned method and means integrally combine carrying-in, setting, inspecting, correcting and carrying-out operations for the door frame in one consecutive process to remarkably shorten the correcting process of the door frame and yet highly qualified corrected door frame is rapidly produced.
