Technical field
The utility model is related to measure the technical field of object elasticity modulus, the ten thousand of especially a kind of measurable elasticity modulus
It can testing machine.
Background technology
Material is in elastic deformation stage, stress and strain direct proportionality（Meet Hooke's law）, ratio system
Number is known as elasticity modulus.The measuring process of existing elasticity modulus is：First object under test is positioned on the testing stand of forcing press, profit
Apply constant pressure with forcing press measuring targets, presses after a period of time, unload object and measure the deflection of object, will adopt
The pressure value of collection is compared with deflection, to obtain elasticity modulus.However, only with the elasticity modulus measured is once tested not
Accurately, there are errors.In addition, after finishing experiment on forcing press every time, it is also necessary to deflection is measured, process is increased,
Labor intensity is increased, there are the low defects of measurement efficiency.
Utility model content

Specific implementation mode
The utility model is further described below in conjunction with the accompanying drawings, the scope of protection of the utility model be not limited to
It is lower described：
As shown in Figure 1, a kind of universal testing machine of measurable elasticity modulus, it includes portal frame 1 and computer 2, described
The bottom of 1 crossbeam of portal frame is installed with hydraulic press 3,3 vertical setting of hydraulic press, and the effect end of 3 piston rod of hydraulic press is fixed
There are sliding block 4, the bottom of sliding block 4 to be provided with pressure head 5；The lower section of the pressure head 5 is provided with plummer 7, and the bottom of sliding block 4 is provided with
Extensometer A8 and extensometer B9, extensometer A8 and extensometer B9 are symmetrical arranged about pressure head 5, the hydraulic press 3, extensometer A8 and
Extensometer B9 is connect with computer 2 by signal wire 12.
Guide rail 10,10 vertical setting of guide rail are provided on the column of the portal frame 1.The left and right end of the sliding block 4 is all provided with
It is equipped with sliding sleeve 11, the sliding sleeve 11 is slidably mounted on guide rail 10.
The course of work of the utility model is as follows：Object under test 13 is first positioned over the top of plummer 7, and by extensometer A8
The bottom of grips object under test 13 top of the grips object under test 13 of extensometer B9 is then controlled into hydraulic pressure
3 piston rod of machine extends downwardly, and pressure head 5 is pressed in the top of object under test 13, and hydraulic press 3 transmits pressed power, meter to computer 2
Calculation machine 2 obtains stress value suffered by object under test, while extensometer A8 and extensometer B9 acquisition objects under test occur in vertical direction
Strain, extensometer in real time will strain size be transferred to computer 2, by change 3 applied force of hydraulic press can test out difference
The strain size that object occurs under stress, stress-strain curve is drawn out by computer data acquisition, to be measured to obtain
The elasticity modulus of object.Therefore this testing machine obtains the elasticity modulus of object under test by multi-group data, measurement accuracy higher, together
Shi Caiyong computers carry out statistical data, improve measuring speed, have the characteristics that high degree of automation.
