Description
Technical field
The utility model is a kind of roller distance measurement instrument that is used to measure space between two parallel rollers surfaces, particularly a kind of roller spacing electromagnetism measurement apparatus that uses the electromechanical integration that the electromagnetic measurement principle makes.This measuring instrument is also applicable to the measurement of other two parallel cylindrical bodies spacings.
Background technology
Existing roller distance measurement, employing be the clearance gauge method, promptly place two rollers with a round steel post that is slightly less than the roller spacing, use the sheetmetal of different-thickness again, insert remaining space, draw the size of roller spacing thus.For example, the round steel post that is 200mm with a standard length places between two rollers, with the sheetmetal of a 0.1mm, insert remaining gap, if can pass through, use the sheetmetal of another 0.2mm again instead, as can not passing through, then the spacing between two rollers is between 200.1mm～200.2mm.The shortcoming of this method is that operating difficulties is loaded down with trivial details, takes time and effort, and measurement result is subjected to gauger's level affects very big, needs to prepare the cover measurer suitable with the measuring object range, and full accuracy is limited as 0.1mm, can't further improve.
At present also favourable roller distance measurement instrument with electronic measurement technique, it is to adopt small-sized displacement transducer as measuring head, and instrument internal is provided with sensor, transmitter, microprocessor, battery etc., and external signal is connected with sensor by mechanical linkage.Existing roller distance measurement instrument, the complex structure volume is big, needs often to change battery or charging, carries operation inconvenience.
Summary of the invention
The purpose of this utility model is low in order to overcome existing clearance gauge method operating difficulties precision, and the existing roller distance measurement instrument complex structure volume defective of portable band very much not, invent a kind of roller spacing electromagnetism measurement apparatus that adopts electromagnetic measurement, numeral demonstration, structure small volume and less weight, energy saving, long service life.
The purpose of this utility model realizes as follows: described roller spacing electromagnetism measurement apparatus, form by two relatively-movable assemblies, and one is locking assembly, is positioned at the bottom of instrument, another is moving assembly, is positioned at the top of instrument; Locking assembly is provided with a long steel bar, pitch circuit inner panel such as is provided with along long steel bar length direction; Moving assembly such as is provided with at pitch circuit outside plate, has a rectangular channel on the moving assembly inside to be free to slide for long steel bar, is provided with spring between long steel bar and the moving assembly, and locking assembly and moving assembly are expanded outward from each other.
The bottom of described locking assembly is smooth circular arc, and the top of moving assembly also is smooth circular arc.
Described moving assembly is provided with button, LCDs, electrical interface.
Good effect of the present utility model is as follows: simple in structure, and Electromechanical Design, in light weight, can be hold by one hand operation; Two ends outside arc design, under the effect of elastic force, automatically with the line of two roller center as slotted line, and be difficult for from landing between roller; Up and down measuring head totally three some touch roll sub-surface can guarantee slotted line perpendicular to roller surfaces, eliminate positioning error; In measurement range, built-in spring provides constant dynamometry, can avoid gauger's gimmick error; Electromagnetic measurement mechanism can follow the stepless slip of measuring head, exports measurement data continuously, eliminates gauger's reading error.

Embodiment
Shown in Figure 2 as Fig. 1, described roller spacing electromagnetism measurement apparatus is made up of two relatively-movable assemblies, and one is locking assembly 1, is positioned at the bottom of instrument, and another is moving assembly 2, is positioned at the top of instrument; Locking assembly 1 is provided with a long steel bar 3, pitch circuit inner panel (failing among the figure to draw) such as is provided with along long steel bar 3 length directions; Moving assembly 2 such as is provided with at pitch circuit outside plate (failing among the figure to draw), having a rectangular channel 4 on the moving assembly 2 inside is free to slide for long steel bar 3, be provided with spring (failing among the figure to draw) between long steel bar 3 and the moving assembly 2, locking assembly 1 and moving assembly 2 are expanded outward from each other.
The bottom of described locking assembly 1 is smooth circular arc, and the top of moving assembly 2 also is smooth circular arc.The good effect of this technical scheme runs into the smooth cylindrical roller period of the day from 11 p.m. to 1 a.m when locking assembly 1 and moving assembly 2 under the spring force effect expand outwardly mutually, and both lines will be positioned at plane, roller center line place automatically.
Described moving assembly 2 is provided with button 5, LCDs 6, electrical interface 7.The good effect of this technical scheme is to be convenient to operation, reading, is convenient to and extraneous communication.
The utility model be with in the locking assembly etc. pitch circuit inner panel as a pole plate, with in the moving assembly etc. pitch circuit outside plate be another pole plate, two mutual displacements of pole plate, cause electric capacity and/or variation inductance, the computing of detection, amplification, arrangement and microprocessor by electronic package is shown in displacement measurement on the LCDs.
During measurement, locking assembly and moving assembly are close to roller surfaces, and two pole plates relatively move with mechanical member and produce the variation of electric capacity or inductance value, are collected to amplify by electronic circuit and send microprocessor to calculate, on LCD panel, show with digital form, and can be by interface to external transmission.
Locking assembly of the present utility model and moving assembly have been formed with respect to the automatic centering location structure of cylindrical roller up and down, in case locking assembly and moving assembly contact at roller surfaces, described centering location structure can guarantee that roller center line and apparatus measures center line are on same plane, in actual use, can move/rotate instrument a little, the variation of observed reading represents that instrument just in time is in the center when reading is maximum, and read off this moment gets final product.
The electronic circuit advanced person that the design of this instrument is adopted is energy-conservation, only generally can use the several years with button cell.
This apparatus measures is accurate, and resolution can reach 0.01mm.
The utlity model has the characteristics such as simple in structure, automatic centering, constant, the stepless electrical measurement of dynamometry, numeral demonstrations, eliminated the error of manual measurement reading, particularly in the occasion of flight-line maintenance, continuous numeral demonstration provides great convenience to adjustment. The occasion that the utility model need to be measured spacing between two rollers of assessment in fields such as metallurgy has extensive and important application.
