An automated parts assembly station includes positioning means (11) having surfaces (15a, 16a) for defining a desired mutual position of the parts to be assembled and assembly means (13) connecting the parts. At some of the surfaces (15a, 16a) there are measurement means (18) for measuring a distance between the surfaces and facing surfaces of the parts being assembled. A method is provided for the timely detection of the assembly tolerances. The method includes the steps of performing with the positioning means a permanent positioning of the parts being assembled, operation of the assembly means for connecting the parts, and releasing of the positioning means. Additionally, there is a measurement of the distance between the assembled parts and some of the surfaces. This measurement includes a comparison of the measured distances with maximum admissible distances. At the end, the method generates an acceptance or non-acceptance signal depending on whether the distances measured are greater or less than the related maximum admissible distances.
