Abstract:
In an automated parts assembly station comprising positioning means having surfaces defining a desired mutual position of parts to be assembled and assembly means connecting the parts, at least some of said surfaces having measurement means for measuring a distance between said at least some surfaces and facing surfaces of the parts being assembled, a method for a timely detection of assembly tolerances comprises the steps of:performing with the positioning means a permanent positioning of the parts being assembled,operating the assembly means for connecting the parts,releasing the positioning means to take said parts to a loose positioning condition of the parts,measuring with the measurement means the distance between the assembled parts and said at least some surfaces,comparing the measured distances with related maximum admissible distances, andgenerating an acceptance or non-acceptance signal depending on whether the distances measured are greater or less than the related maximum admissible distances.
