Description
Technical field
The utility model belongs to mechanical hook-up, is specifically related to the displacement that a kind of microscope stage uses and the multifunctional loading unit of power sensing.
Background technology
As everyone knows, quilts such as various microscopes and little Raman spectrometer, little infrared spectrometer, XRD diffractometer are widely used for observing the material microscopic pattern, distinguish material composition and kind.Along with going deep into of scientific research, people need influence the object imposed load of being studied on the objective table of various microsurgical instruments, further probe into physics under the micro-scale, mechanical property and behavior.Because the objective table major function of various microsurgical instruments is to place sample, and can carry out three-dimensional high-precision and move (micron dimension), so that examine under a microscope the pattern of sample diverse location.But the popular feature of present various microscope stages is that spatial volume is narrow and small and can not place too heavy articles, otherwise influences the precision of objective table three-dimensional motion.If when observing the object microstate, can stretch or experimental study such as compression, can't carry out according to the project organization of present microscope stage to sample.
Given this, proposition of the present utility model is carried out problems such as multi-functional operation such as dynamic load and power sensing when can solve on microscope stage the sample micromechanism observed.
Summary of the invention
The purpose of this utility model provides multifunctional loading units such as displacement loading that a kind of microscope stage uses and power sensing.
The utility model is achieved by following technical pattern.Multifunctional loading unit for objective table of microscope (as figure) mainly has: fixedly fixture block 1, screw 3, framework 4, ball slideway 5, ball 6, mobile fixture block 7, force transducer 8, rotation/translation conversion block 9, milscale screw rod 10 etc.The specific design structure is: fixedly fixture block 1 is provided with two oval dead slots 2, screw 3 pass oval dead slot 2 fixedly fixture block 1 be connected with framework 4.Can fix the particular location of fixture block 1 by adjusting screw, to adapt to the length of sample at framework 4.Two ball slideways 5 are by in 4 screw fixed frame 4 grooves, and ball 6 is loaded in the groove of mobile fixture block 7 both sides and with ball slideway 5 and is slidingly connected, to reduce the resistance of mobile fixture block 7 along axis X linear slide.Mobile fixture block 7 is fixedlyed connected with force transducer 8 by screw 3; Rotation/translation conversion block 9 is also fixing with force transducer 8 by screw 3.Milscale screw rod 10 passes framework 4 and is assembled in rotation/translation conversion block 9, and the displacement load information is read by the scale on the milscale screw rod 10.The power load signal spreads out of by the signal wire that is connected in force transducer 8.Fixedly 5 component-assembled such as fixture block 1, mobile fixture block 7, force transducer 8, rotation/translation conversion block 9 and milscale screw rod 10 are in the same axis X of framework 4 planar central; Oval dead slot 2, ball slideway 5 and ball 6 are parallel with this axis X and according to axis X symmetry.The front end of milscale screw rod 10 is spherical, and the outside of rotation/translation conversion block 9 is provided with circular trough.The spherical front end of milscale screw rod 10 is bumped into and constitutes articulated type in the circular trough of rotation/translation conversion block 9 and connect, and the rotation displacement of milscale screw rod 10 can be changed into the straight-line displacement along axis X of rotation/translation conversion block 9, force transducer 8, mobile fixture block 7.Fixedly the surface of fixture block 1 and mobile fixture block 7 is provided with test specimen bolt 11, and the center of circle of test specimen bolt all is positioned on the X of axis.Framework 4 bottoms (fixedly between fixture block 1 and mobile fixture block 7 positions) have rectangle dead slot 12, its objective is that multifunctional loading unit can throw light on from the sample bottom.
Description of drawings
Accompanying drawing is a structure principle chart of the present utility model.
Embodiment
Below by concrete operation method the utility model is further described.By structure shown in the drawings each parts is assembled.Concrete operation method is: the two ends of sample are fixed in fixedly on the fixture block 1 and mobile fixture block 7 by test specimen bolt 11 respectively on the objective table, because the center of circle of test specimen bolt 11 all is positioned at axis X, test specimen is carried out without acceptance of persons uniaxial tension or compressive load so can guarantee this multifunctional loading unit.
Adjusted size according to sample is fixedly also fixed the position of fixture block 1, adjusts the milscale screw rod simultaneously and reserves the load deflection surplus; The initial value of verification force transducer 8 makes zero load by adjusting milscale screw rod 10, writes down the scale of milscale screw rod 10 at this moment, as the Relative Zero displaced position; The position of this charger being fixed on the microscope stage of Raman spectrometer (X-ray diffractometer) and adjusting objective table makes that to enter the microscopical visual field be Raman (X-ray diffraction) signals collecting zone for the zone that is studied of test specimen; In the displacement loading that realizes by rotation milscale screw rod 10 test specimen, the record output signal of force transducer 8 and the scale of milscale screw rod 10, and the Raman spectrum (or X-ray diffraction spectrum) before and after the collected specimens load or sample carried out microstructure observation.Carry out straight line by the mobile fixture block 7 of rotation milscale screw rod 10 promotions along axis X and move, realize stretching or compression-loaded function sample.The displacement load information is read from the scale on the milscale screw rod 10; The power load signal then spreads out of in real time by the signal wire that is connected in force transducer 8.Be equipped with modulus signal conversion and display instrument, measured state parameter is demonstrated.
Characteristics of the present utility model and beneficial effect are, specially for being widely used in little Raman spectrometer, X-ray diffraction The stage design of instrument and multiple microscopy instrument has volume little (maximum ga(u)ge only is 16mm), lightweight characteristics.
