Description

Technical Field

[0001] The utility model relates to a calibration device, in particular to a tape measure calibration device. Background Art

[0002] Steel tape measure is a common length measuring instrument, which is widely used in industrial and agricultural production and daily life, such as engineering measurement, area measurement, workpiece size measurement, etc. Steel tape measure is a commonly used measuring tool in industrial and mining enterprises and institutions. In the production process of steel tape measure, there will be errors in the scale engraving, and the larger the range of the steel tape measure, the greater the error. Especially for steel tape measure with a range of more than 5m, the error in the scale engraving has affected the measurement result of the steel tape measure, so it is very necessary to verify the accuracy of the steel tape measure.

[0003] The commonly used steel tape measurement calibration device adopts a gantry pulley structure with rollers. The gantry pulley is equipped with a reading microscope that spans across the steel tape measurement calibration table. The calibration personnel move the gantry pulley to the inspected position and read the scale error value of the steel tape measurement through the reading microscope. When placing the steel tape measurement, the calibration personnel need to pass the steel tape measurement belt through the middle of the gantry pulley or lift the gantry pulley. After the steel tape measurement is placed, the gantry pulley is put back on the track; after the calibration is completed, when taking out the steel tape measurement, it is also necessary to pass the steel tape measurement belt through the middle of the gantry pulley or lift the gantry pulley. The entire process of taking and placing the steel tape measurement is very inconvenient, time-consuming, and labor-intensive.

[0004] Application number: CN202121600810.2 A steel tape measure calibration device with an open pulley, comprising a steel tape measure calibration platform, a steel tape measure fine-tuning device, a guide rail, and an open pulley. The steel tape measure calibration platform is spliced ​​by profiles and can be extended as needed. The surface of the steel tape measure calibration platform is composed of rollers placed at intervals; the steel tape measure fine-tuning device includes two sets of manual slides and two tape clamps, and the tape clamps are respectively fixed on a single manual slide, and the steel tape measure fine-tuning device is fixed on the left end face of the steel tape measure calibration platform. The guide rail is fixed on the inner side of the steel tape measure calibration platform and is parallel to the placement direction of the steel tape measure on the surface of the steel tape measure calibration platform.

[0005] Such a structure is particularly inconvenient to detect nowadays because it occupies a large space. Utility Model Content
