End measure comparator for comparing parallel end measures in a horizontal position

摘要

An end measure comparator for comparing parallel end measures (8) in a horizontal position with an end measure comparison standard of the same nominal dimension, having a stop (7) for determining the measuring position of the parallel end measure to be tested, having bearings (9) for supporting the two parallel end measures (8) at the most favourable points which permit pivoting of the parallel end measures (8), and having a scanner (7), which can be displaced on a carriage (6) and is connected to a measuring sensor for determining relative length, for the end faces of the parallel end measures can be completely remote controlled and entirely encapsulated against radiative transfer between the housing interior and the housing exterior when the arrangement is surrounded on all sides by a thermally insulating, radiation-reflecting housing (12), when a thermostatically controlled temperature-controlling device (13) is provided inside the housing (12), when there is an air circulation (15) which uniformly embraces the interior of the housing (12), when the bearings (9) can be adjusted in a strictly rectilinear fashion in the two coordinate directions which are perpendicular to the longitudinal extent of the parallel end measure (8), when the bearings (9) can be adjusted by means of the end scanning in such a way that for every length they permit support at the most favourable points and when sensors (10) are provided on the end faces for the purpose of determining the edge positions of the parallel end measures (8) (Figure 1).
