[0002] A steel tape measure calibration device is a device used to verify and calibrate steel tape measures. It is commonly used in industrial production, particularly where precise measurements are required. Regular verification and calibration of steel tape measures ensures the accuracy of measurement results, improving the quality and efficiency of production processes. It also helps users comply with industry standards and regulations, ensuring that products meet specified quality requirements.

[0003] Steel tape measures are commonly used measuring tools in industrial and mining enterprises and institutions. During the production process of steel tape measures, there will be errors in the engraving of the scale, and the larger the measuring range of the steel tape measure, the greater the error. The calibration process of the steel tape measure is as follows: the steel tape measure to be tested and the standard steel tape measure are placed parallel to each other on the calibration table, weights are loaded on the ends of the tested ruler and the standard ruler to apply the rated tension, the zero scale lines of the tested ruler and the standard ruler are aligned, and then the scale lines of the tested ruler and the standard ruler are compared. When the length of the tested ruler is greater than the length of the calibration table, the tested ruler needs to be measured in sections. Depending on the number of sections, the zero scale alignment needs to be performed multiple times, and the scale lines of the tested ruler and the standard ruler need to be read with the naked eye or a handheld microscope to see if they are consistent. However, the existing steel tape measure inspection requires manual movement and replacement, which has low inspection efficiency and wastes labor costs. Utility Model Content
