Third-class metal line scale standard device

Abstract

The invention discloses a third-class metal line scale standard device. The device comprises a workbench, supporting columns are fixedly connected to the bottom end of the workbench at equal intervals, threaded rods are in threaded connection with the bottom ends of the supporting columns, base plates are fixedly connected to the bottom ends of the threaded rods, a standard scale is connected to the surface of the workbench in an embedded mode, and an electric sliding rail is fixedly installed on one side of the top end of the workbench. An electric sliding block is fixedly mounted in the electric sliding rail. In the invention, the automatic measuring method of the measuring device replaces manual measurement, and the machine vision reading replaces naked eye reading, so the operation issimple and convenient, the measuring efficiency is high, and the enterprise steel tape measuring work requirements can be met; the standard scale is arranged on a calibration table, a standard steel tape does not need to be installed, and a set of machine vision detection device is configured; so indication errors of the steel tape and a steel ruler to be inspected can be conveniently and clearlyidentified; and an automatic guide rail and a guide rail control system are arranged, so the vision detection device can be accurately moved to an inspection position according to inspection requirements, and the number of test points can be selected according to test requirements.

Description

technical field [0001] The invention relates to the technical field of metal thread ruler detection equipment, in particular to a third-class metal thread ruler standard device. Background technique [0002] The metal line ruler standard device is an automatic detection device that adopts an automatic measurement method, uses a PLC controller to control the motor module, drives the measuring camera to move within the length range of the steel tape, and uses the camera to measure the scale of the steel tape at the specified test point. One measurement can be made on two steel tapes. [0003] The existing third-class metal thread ruler standard device needs to fix the metal thread ruler through multiple fixtures during its use, which is cumbersome to operate, and the visual inspection device is prone to shaking during the moving process, which is easy to detect. The numerical value causes deviation, and when the metal line ruler is bent, it will cause deviation to the detecte...
