Abstract

The invention discloses an automatic verification system for a steel tape, comprising a horizontal horizontal support, a zero alignment device, a tension loading and unloading device and a camera, wherein the zero alignment device, the tension loading and unloading device and the camera are all arranged on the horizontal horizontal support superior. The zero alignment device includes a precision displacement table, a clamping mechanism for the tested scale and a clamping mechanism for the standard scale. The tension loading and unloading device includes the clamping mechanism of the checked ruler and the loading mechanism that drives the clamping mechanism of the checked ruler to move rightward to apply the rated tension force to the checked ruler. The invention also discloses a verification method of the automatic verification system for the steel tape measure. When the verification system of the present invention is applied, it is convenient to realize loading and unloading of steel tape tension force and zero alignment during the verification process, can reduce labor intensity, and can improve work efficiency and measurement accuracy.

Description

technical field [0001] The invention relates to a steel tape measuring technology, in particular to an automatic checking system and a checking method for a steel tape. Background technique [0002] Steel tape is a length measuring instrument widely used in daily life. According to the national steel tape measurement and verification regulations, the steel tape verification process is: place the inspected steel tape (inspected ruler) and the standard steel tape (standard ruler) in parallel on the verification platform, and load weights on the ends of the inspected ruler and the standard ruler Apply the rated tension, align the zero scale lines of the tested scale and the standard scale, and then use the measurement method of comparing the scale lines of the tested scale with the scale lines of the standard scale. When the length of the inspected ruler is greater than the length of the verification table, it is necessary to measure the inspected ruler in sections. According ...
