Magnetic induction ruler reading head calibration device

Abstract

The utility model relates to an adjusting device for the inductive reading head of a magnetic inductive ruler, mainly comprising a sensor unit, a signal display unit and a signal output unit, wherein the sensor unit comprises a hall sensor which generates a square wave signal in case of detecting the magnetic ruler; the signal display unit comprises a display component which can display the signal state of the sensor unit; the signal output unit can transform the signal of the sensor unit into a group of Z and / Z signals to transmit to the host computer for reading and measuring; the sensor unit can generate a signal in case of the reading head approaching to the working space of the magnetic ruler and inform the user through the action of the display component to facilitate the user to install the inductive reading head correctly and swiftly.

Description

technical field [0001] The present invention is related to the induction reading head of the magnetic induction ruler, more specifically, it relates to an induction reading head device which has a display unit to display the correct installation distance, and has a reference point signal output function at the same time. Background technique [0002] The installation methods of the induction reading head of the traditional magnetic ruler are roughly divided into the following types: [0003] 1. Using visual installation does not require any tool assistance, but it is easy to cause the installation time distance to be greater than the effective sensing distance due to visual errors or differences in personal skills, making the sensing reading head unable to operate normally, requiring repeated adjustments and calibrations to achieve Make the induction reading head move smoothly; [0004] 2. Use a ruler to install. When the sensor reader is installed on the machine equipment,...

Problems solved by technology

[0003] 1. Using visual installation does not require any tool assistance, but it is easy to cause the installation time distance to be greater than the effective sensing distance due to visual errors or differences in personal skills, making the sensing reading head unable to operate normally, requiring repeated adjustments and calibrations to achieve Make the induction reading head move smoothly;

[0004] 2. Use a ruler to install. When the sensor reader is installed on the machine equipment, use a ruler to measure the installation distance between the sensor reader and the magnetic ruler to ensure that it falls within the effective sensing distance; but this installation method is time-consuming , Inconvenient to use, when the machine tool space is small, it is not easy to measure correctly;

[0005] 3. Use special jigs for installation, and use jigs such as gaps to assist technicians to install, which can simplify the installation action and achieve the correct installation spacing, but it is necessary to develop suitable auxiliary jigs for each model, and the number of auxiliary jigs required is large. Causes additional cost increase, not the most effective solution
