Description

Extensometer measuring system calibrating installation
Technical field
The utility model belongs to measuring technique, relates to a kind of extensometer measuring system based on raster pattern table class measurer calibrating instrument.
Background technology:
In the engineering goods development and production, mechanical property is the basic parameter that any product starting material all must be tested, extensometer then is to be used for the crucial measurement instrument of test material mechanical property on the Material Testing Machine, be the sensor of measuring the distortion of starting material trace line, be used for starting material Rp (Proof strength of non-proportional) parameter measurement.Because extensometer is mounted in the Material Testing Machine, bad disassembling is still again without the measuring equipment of implementing field calibration.Outer censorship also is single extensometer is demarcated, and can not reflect the authenticity of extensometer measuring system, and the calibrating time is long, affects the research and production progress.
The utility model content
The purpose of this utility model is: a kind of field calibration, extensometer measuring system calibrating installation that the Measurement and calibration precision is high of being applicable to is provided.
The technical solution of the utility model is: a kind of extensometer measuring system calibrating installation, it comprises table class measurer calibrating instrument, movable axle, measured material, described table class measurer calibrating instrument is made of orthogonal support platform with slide rail and gauged distance control boss, be provided with in this gauged distance control boss and be parallel to the boss slide rail, be used for providing the screw mandrel of gauged distance control, measured material is arranged on the slide rail, movable axle is divided two parts, a part is arranged on the measured material, another part links to each other with screw mandrel, above-mentioned two parts screw mandrel is strictly coaxial, and during actual measurement, two measuring claws of extensometer are connected on above-mentioned two parts axle.
This table class measurer calibrating instrument is raster pattern table class measurer calibrating instrument or mechanical type table class measurer calibrating instrument or step-by-step movement table class measurer calibrating instrument.
Be provided with an extension plate on the measured material, be provided for the measured material of fixing movable axle on this extension plate.
The beneficial effects of the utility model are: the utility model extensometer measuring system calibrating installation design one cover volume is little, lightweight, intensity is high, being easy to carry meets the frock that the extensometer measuring system is truly used state, under the prerequisite that does not affect raster pattern table class measurer calibrating instrument normal function, can realize each rank, different structure type extensometer measuring system field calibration, make align mode reach consistent with the use state, more can reflect accurate, the authenticity of extensometer measuring system.Solve owing to having increased complicated frock, may cause that raster pattern table class measurer calibrating instrument precision reduces problem, its measuring accuracy is high: in the omnidistance 50mm scope, the error of indication≤0.5 μ m within any 1mm, the error of indication≤1.5 μ m within any 10mm, the error of indication in the omnidistance 50mm scope≤3 μ m.
Description of drawings
Fig. 1 is the structural representation of the utility model extensometer measuring system calibrating installation, wherein, and the 1-extensometer; 2-table class measurer calibrating instrument; The movable axle of 3-; The 4-measured material; The 5-screw mandrel.
Embodiment
The utility model will be further described below by specific embodiment:
See also Fig. 1, it is the structural representation of the utility model extensometer measuring system calibrating installation.Described extensometer measuring system calibrating installation is converted by table class measurer calibrating instrument, and it comprises table class measurer calibrating instrument 2, movable axle 3, measured material 4.Described table class measurer calibrating instrument is made of orthogonal support platform with slide rail and gauged distance control boss.This gauged distance is controlled to be provided with in boss and is parallel to the boss slide rail, is used for providing the screw mandrel 5 of gauged distance control.Described measured material is arranged on the slide rail, can be mobile at slide rail, and to be used for extensometer 1 pawl apart from coarse adjustment.Movable 3 minutes two parts of axle, a part is arranged on the measured material 4, and another part links to each other with screw mandrel 5, and above-mentioned two parts screw mandrel is strictly coaxial.During actual measurement, two measuring claws of extensometer are connected on above-mentioned two parts axle.In addition, when extensometer measuring claw spacing is excessive, can connects an extension plate in former measured material 3, and be provided for the measured material of fixing movable axle 3 at extension plate, to improve measurement range.
Count example take measuring distance as 2 millimeters extend, during the actual measurement of the utility model extensometer measuring system calibrating installation, first take the not stressed place of extensometer as measuring zero point, then, regulate screw mandrel take 0.2 millimeter as step-length pulling axle, and read the extensometer reading of each 0.2 millimeter step-length.After covering whole process, the corresponding extensometer reading of each step-length is carried out data process, according to result extensometer is measured grade and evaluate.
Described table class measurer calibrating instrument can be the calibrating instrument of mechanical type, step motor type or raster pattern, and take raster pattern table class measurer calibrating instrument as example, its inner grating can be controlled the screw mandrel step-length accurately, to guarantee calibration accuracy.
The utility model extensometer measuring system calibrating installation can be realized each rank, different structure type " extensometer measuring system field calibration " under the prerequisite that does not affect table class measurer calibrating instrument normal function, expanded the use function of table class measurer calibrating instrument.This extensometer measuring system calibrating installation volume is little, lightweight, intensity is high, be easy to carry, and meets the extensometer measuring system and truly uses state, is applicable to field calibration.And measuring accuracy is high, in the omnidistance 50mm scope, the error of indication≤0.5 μ m within any 1mm, the error of indication≤1.5 μ m within any 10mm, the error of indication≤3 μ m in the omnidistance 50mm scope make align mode reach consistent with the use state, solve owing to having increased complicated frock, may cause that raster pattern table class measurer calibrating instrument precision reduces problem, more can reflect accurate, the authenticity of extensometer measuring system.
