Background technology
Scientific research be unable to do without the exploitation of science and technology and instrument, in order will the detection of the measurement of nano material and Mechanical Properties of Products and microscopic appearance to be organically combined, academia and engineering technological are being developed some mechanics test devices and are being come and scanning electron microscope (SEM), transmission electron microscope (TEM), the micro-nano optical viewers such as atomic force microscope (AFM) are used in conjunction with, thereby can in depth explore microscopic damage fracture behaviour and the mechanism of all kinds of nano materials and goods, and and load, material structure and performance between correlativity rule.
There is now a kind of horizontal dynamic and static electrohydraulic-servo microexamination testing machine, mainly by main frame, hydraulic power source, composition of the control system.Wherein, main frame is provided with adjusts oil cylinder subsystem, and servo-cylinder is from system, and optical microscope and three-dimensional Mobile Slide, for sample provides experiment porch; And by computer control.But this machine construction is comparatively complicated, structure is special, can not meet the space that atomic force microscope can be worked, thereby also cannot support the use with atomic force microscope, thereby cannot when sample being carried out to Compression and Expansion operation, utilize atomic force microscope observation sample urn Topography to change.Therefore be necessary to manufacture and the matched horizontal material extending compression test of atomic force microscope.
Summary of the invention
For limitation of the prior art, the object of the invention is, a kind of and matched material extending compression test of atomic force microscope is provided.
The present invention adopts following technical scheme:
The horizontal material extending compression test of the supporting use of atomic force microscope, includes gear train, servomotor and power supply; It is characterized in that, gear train comprises leading screw, moving beam, speed reduction unit, left fixture, right fixture;
The table top of framework is hollow structure, in its left crossbeam, is provided with servomotor, power supply; In framework all side beam, rear curb girder, be respectively arranged with leading screw, moving beam two ends two leading screws that are in transmission connection respectively; The rotation axis of two leading screw one end is affixed with two engaged wheels respectively, and engaged wheel is in transmission connection by circular arc synchronous toothed belt and speed reduction unit; Speed reduction unit is connected with servo motor transmission;
Left fixture is fixed on left crossbeam inner side above, and right fixture is fixed on power sensor, and power sensor is fixed on movable beam.
After the present invention and atomic force microscope are supporting, can sample is stretched and the Mechanics Performance Testing such as compression in sample is carried out to atomic force microscope test.The present invention can be for the measurement to samples such as organic and inorganic, compound substances.
When the present invention applies, forward and backward curb girder, moving beam and left crossbeam are work space, make the present invention and atomic force microscope supporting.The two ends of test sample are separately fixed on left fixture and right fixture, have screw screw on fixture, can make fixture tightly clamp sample after tighten the screws; By left fixture and right clamp clamps sample two ends, make test specimens product be positioned at the below of atomic force microscope probe 15, in work space.By the use of combining of the present invention and atomic force microscope, thus the macro-mechanical property of analytical sample and the microscopic damage fracture behaviour under stretching/compressing condition, and and load, material structure and performance between correlativity rule.
The present invention adopts horizontal type structure, simple in structure, easy to use, can meet the space that atomic force microscope can be worked, can to sample, stretch or be compressed to the surface topography that to a certain degree utilizes afterwards atomic force microscope measurement sample, thereby analyze, stretch or the impact of compression on sample structure.The present invention simultaneously also can measure the macro-mechanical property of sample.Thereby the advantage of the advantage of atomic force microscope and omnipotent mechanical test machine can be combined, and result of use is good.
