Abstract
The utility model discloses a straingauging structure, its characteristic includes: resistance strain gauge, elastomeric element, installing component, resistance strain gauge fixes on one side of elastomeric element, and elastomeric element's opposite side is fixed on the installing component to the installing component is with the straingauging structure of resistance strain gauge and elastomeric element laminating formation unit under test on the unit under test. The utility model discloses can quick accurate measurement strain force to the measurement of efficiency and the degree of accuracy improve.
Description
Technical field
This utility model is related to a kind of strain measurement structure, for measuring the strain value of testee.
Background technology
In industrial design or use, intensity after stress when mechanical part will consider actually used, to guarantee its use
Safety or be used for monitor its stress size, strain measurement is just used to strain value after testing machine tool part stress, thus reaching
To above-mentioned purpose.
The method of strain measurement at present is typically all to be pasted onto on unit under test strain ga(u)ge by glue, Ran Houjing
Cross the technological operations such as pressurization, temperature-curable and just can complete taping process, produce strain when unit under test stress deforms, solidification
By on this strain transfer to strain ga(u)ge, strain ga(u)ge just can collect the strain value of unit under test to paster glue afterwards.
But in actually used, the process of this adhering resistance strain gauge is limited by technique, and operation sequence is complex, not only cause to grasp
Make difficult, and strain ga(u)ge often occur pasting closely, easily come off, thus the strain measurement value of collection is inaccurate or adopts
Collection less than.
Utility model content
This utility model is to solve the weak point that prior art exists, and proposes a kind of convenient strain measurement knot installed
Structure, to can fast and accurately measuring strain power, thus improving measurement efficiency and accuracy.
This utility model solves technical problem and adopts the following technical scheme that
A kind of feature of this utility model strain measurement structure includes: strain ga(u)ge, elastomeric element, installing component；
Described strain ga(u)ge is fixed on the side of described elastomeric element, and the opposite side of described elastomeric element is fixed on institute
State on installing component, with described installing component, described strain ga(u)ge and elastomeric element are fitted on unit under test described in being formed
The strain measurement structure of unit under test.
The feature of strain measurement structure described in the utility model lies also in, described installing component and described unit under test it
Between be magnet attraction structure or steel ring fixed structure or screw fastening structure.
Compared with the prior art, the beneficial effects of the utility model are embodied in:
Strain ga(u)ge is fixed on by this utility model to be had on softer elastomeric element, then passes through elastomeric element by electricity
Resistance strain gauge is pressed on unit under test, so that strain gauge is contacted closely with unit under test, when unit under test is deformed by external force,
Contact close strain ga(u)ge and elastomeric element is followed simultaneously and deformed, strain ga(u)ge can collect tested completely
The strain of part, it is achieved thereby that strain measurement, reduces measurement complexity, improves measurement efficiency and accuracy rate.
Brief description
Fig. 1 is this utility model application structure schematic diagram；
In figure label: 1 strain ga(u)ge；2 elastomeric elements；3 installing components；4 units under test；5 steel rings.
Specific embodiment
In the present embodiment, as shown in figure 1, one kind fast and accurately strain measurement structure, comprising: strain ga(u)ge 1, bullet
Property part 2, installing component 3；
Strain ga(u)ge 1 is fixed on the side of elastomeric element 2 (such as silastic material), and is incited somebody to action by elastomeric element 2
Strain ga(u)ge 1 is pressed on unit under test 4, and the opposite side of elastomeric element 2 is fixed on installing component 3, will with installing component 3
Strain ga(u)ge 1 and elastomeric element 2 are fitted in the strain measurement structure forming unit under test 4 on unit under test 4.
In specific implementation process, magnet attraction can be passed through between installing component 3 and unit under test 4 or steel ring 5 bundlees
Formula is fixed or the mode of screw fastening, so that strain ga(u)ge 1 is fitted tightly with unit under test 4, carries out strain measurement.
In measurement, when unit under test 4 is subject to external force, because of material elastic characteristic inherently, unit under test 4 will be sent out
Change shape, that is, strain, and at this moment contacts close strain ga(u)ge 1 and elastomeric element 2 simultaneously with unit under test 4
Change shape.
When strain ga(u)ge 1 deforms, its resistance accordingly changes, will be by strain ga(u)ge 1 built-up circuit (
As be Wheatstone bridge) and cable will export the signal of telecommunication, the size of the size of the signal of telecommunication and unit under test 4 applying force value,
The linear proportionate relationship of its dependent variable, therefore finally to realize accurately detecting the size of strain value.
