Given this, proposition of the present utility model can solve under the Raman environment filament fiber sample is carried out that small load dynamically applies and problem such as measurement in real time.
Summary of the invention
The purpose of this utility model provides a kind of being placed on the Raman spectrometer objective table filament fiber is carried out the device that small mechanical quantity loads and measures.
The utility model is achieved by following technical pattern.Filament fiber loading measurement mechanism has under the Raman environment: screw, force transducer, nut, postive stop baffle, fine motion contiguous block, framework, ball slide plate, ball, mobile contiguous block, rotation/translation conversion block, milscale screw rod etc.Force transducer is by first screw and frame fixation, and the force transducer right-hand member is provided with postive stop baffle, and postive stop baffle inserts in the groove of framework, to prevent the excessive inefficacy that causes force transducer of tensile load.The central shaft of fine motion contiguous block passes postive stop baffle and force transducer and nut and force transducer and fixes.Two ball slide plates are fixed in the groove of framework by four second screws, ball is loaded in the groove of mobile contiguous block both sides downside, the groove of ball slide plate and ball and mobile contiguous block downside constitutes the linear bearing structure, to reduce the resistance of mobile contiguous block along axis X linear slide.Mobile contiguous block and rotation/translation conversion block is fixed by the 3rd screw.The milscale screw rod passes framework and is loaded in rotation/translation conversion block, and mobile contiguous block displacement information is read by the scale on the milscale screw rod, and the power load signal is spread out of by the force sensor signals line.
And described fine motion contiguous block, mobile contiguous block, rotation/translation conversion block and four component-assembled of milscale screw rod are in the same central axis X of described frame plane.
And the ball slide plate is parallel with this axis X with ball and according to axis X symmetry.
And the front end of described milscale screw rod is spherical, described rotation/translation conversion block be provided with circular trough, the spherical front end edge of milscale screw rod crouches and constitute the articulated type connection in the circular trough of rotations/translation conversion block.The rotation displacement of milscale screw rod can be transformed the straight-line displacement along axis X such as mobile contiguous block.
And be the rectangle dead slot in the middle of the described base of frame, its objective is and use this device to throw light on from the sample bottom.
Characteristics of the present utility model and beneficial effect be, specially under the Raman environment filament fiber being carried out the loading of micro-displacement/power (or strain/stress) and measurement and design, has that volume is little, in light weight, precision is high and non-damageable characteristics.When the filament fiber sample being applied small stretching displacement (or power) load, realize to the small power of fiber sample (displacement) load accurately measure and this loaded-up condition under raman spectroscopy measurement, enlarged the range of application of Raman spectrometer.In addition, this device also can be used as portable micro mechanics loading measurement system, is applied to every test of filament fiber material separately.
