FIELD: physics, measurement. ^ SUBSTANCE: device for calibration of car platform of alignment racks. Invention is related to metering technology and may be used in car industry for calibration of working platforms of alignment racks intended for inspection of vehicle technical condition. Device is intended for measurement of profiles with length of not more than 12 meters, while size of working platform in inspection and car lights adjustment post in longitudinal direction should make at least 15 meters. Invention objective is expansion of measurement range. Stated objective is achieved by the fact that device for calibration of car platform in alignment racks arranged in the form of two structural units comprises the third structural unit. The third structural unit comprises height gage and diaphragm provided with white fringe around hole with diameter that is equal to diameter of expanded light beam, and fixed on height gage frame by means of yoke with stop screw. ^ EFFECT: expansion of measurement range. ^ 5 dwg |
