Description
Technical field
The utility model relates to testing of materials device technique field, particularly relates to a kind of new type low temperature creep tester.
Background technology
In certain temperature environment, material is in the situation that being subject to constant External Force Acting, and its distortion meeting is along with the time constantly increases or dwindles, and this phenomenon is called creep, as vulcanized rubber, plastic or other material, than metal material, creep more easily occurs.
The clamp structure of traditional creep proving installation is yielding, and clamp structure is not put in experimental enviroment case, and the volume of clamp structure is excessive, and the change in displacement test out of true that sample is stretched or is compressed, causes test result error larger.
Utility model content
Based on this, be necessary the problem for the shortcoming of prior art, a kind of new type low temperature creep tester is provided, simple in structure, reasonable in design, clamping device is stable, is difficult for deformation, and test result is accurate.
A kind of new type low temperature creep tester, comprises casing, and described casing is provided with a test environment case, in described test environment case, is provided with clamping device, and described clamping device comprises support and is located at upper platen and the pressing disc in described support; Described support comprises entablature, pillar and sill, and described entablature is positioned at described test environment case, and described pillar one end is connected in described entablature, and the other end of described pillar is connected in sill.
In an embodiment, described pressing disc is connected with connecting link therein, and described connecting link is connected with displacement transducer.
In an embodiment, described sill is provided with slip holder therein, and described slip holder middle part is penetrated with a screw rod, and described screw rod is connected in described connecting link, between described slip holder and connecting link, is provided with strength sensor.
In an embodiment, described slip holder both sides are provided with respectively a line slide rail therein.
In an embodiment, described clamping device is connected with a force application apparatus therein, and described force application apparatus comprises servomotor and synchrome conveying belt.
In an embodiment, described casing is provided with man-machine interface and controls button therein.
Above-mentioned new type low temperature creep tester, simple in structure, volume is little, reasonable in design, exquisite appearance, described test environment case meets low temperature environment test request, and temperature in test environment case is even.The entablature of described clamping device is located in test environment case, and the end of clamping device is connected with displacement transducer, and test result is accurate.
Accompanying drawing explanation
Fig. 1 is structural perspective of the present utility model.
Below the explanation of the utility model parts sign flag:
Embodiment
For further understanding feature of the present utility model, technological means and the specific purposes that reach, function, resolve advantage of the present utility model and spirit, by below in conjunction with accompanying drawing and embodiment, detailed description of the present utility model being further understood.
A kind of new type low temperature creep tester, comprises casing 10, and casing 10 is provided with a test environment case 11, is used to test offering sample low-temperature test environment.In this test environment case 11, be provided with clamping device, clamping device comprises support 23 and is located at upper platen 21 and the pressing disc 22 in support 23.Pressing disc 22 is connected with connecting link 24, and connecting link 24 is connected with displacement transducer (not indicating in figure).This connecting link 24 drives pressing disc 22 to move, extruding test sample, and displacement transducer detects test sample compress variation.
Between slip holder 30 and connecting link 24, be provided with strength sensor 40, the extruding force that the real-time sensing test of strength sensor 40 sample bears.
Clamping device is connected with a force application apparatus.Force application apparatus comprises servomotor 51 and synchrome conveying belt 52.Servomotor 51 is located in casing 10, and synchrome conveying belt 52 one end are connected in the rotating shaft of servomotor 51, and the other end is connected with nut, and this nut is connected with screw rod.Servomotor 51 rotates, and drives synchrome conveying belt 52 to rotate, and then drives described nut rotation.Due to the rotation of nut, described screw rod starts to move up and down, and then drives described connecting link 24 to move up and down.
Using when the utility model, required low temperature environment, compression time, compressing force or compression displacement amount while setting test by described man-machine interface 12.After parameter setting completes, test sample is put in test environment case 11, and lain against on the pressing disc 22 of described clamping device.Then, start test by described control button 13, when after the low temperature environment of the interior temperature of test environment case 11 and setting, described servomotor 51 starts to rotate, and drives synchrome conveying belt 52 to rotate, and then drives described nut rotation.Nut drives screw rod to start to rise, and then drives described connecting link 24 to rise, and described pressing disc 22 starts extruding test sample.Meanwhile, the ascending velocity of described displacement transducer sensing connecting link 24, connecting link 24 is with constant speed rising compression verification sample, strength value when the real-time sensing test sample of described strength sensor 40 is compressed to certain deflection.After reaching the test duration of setting, man-machine interface 12 shows test results, and test finishes.
In sum, above-mentioned new type low temperature creep tester, simple in structure, volume is little, reasonable in design, exquisite appearance, described test environment case 11 meets low temperature environment test request, and temperature in test environment case 11 is even.The entablature 231 of described clamping device is located in test environment case 11, and the end of clamping device is connected with displacement transducer, and test result is accurate.
The above embodiment has only expressed several embodiment of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
