Description
Technical field
The present invention relates to the modulus measurer in Experiment of College Physics, particularly relate to a kind of support of measuring in the intelligent modulus measurer vertically placed.
Background technology
Known at present, all non intelligent using steel wire as the modulus measurer of measured object, the shortcoming of this vertical drawing structure needs a lot of counterweight, deposit cumbersome, careless manipulation, counterweight Crater face easily hurts the foot of operator, and during swing weight-adding, wire rope easily rocks, and measuring error is increased; In operation, the picture of scale is difficult to find in addition, needs the data volume of manual calculations larger in computing formula; Reading and two places, swing weight-adding office, operator needs repeatedly to run between telescope and measurement bay, causes laboratory confusion crowded.
Summary of the invention
The object of the invention is to provide a kind of intelligent modulus measurer to society, to eliminate the shortcomings of current known modulus measurer.
Technical scheme of the present invention is as follows:
Steel wire head fixed plate is fixed on the top of support by the fishbolt carried, pulley is fixed on the bottom of support by adjustable apparatus, getting a segment length is stent length 0.5-0.7 steel wire to be measured doubly, in one section knotting, the other end is connected on the tautness meter of verification through optical lever arrangement.Get the steel wire of a segment length about 1.5 meters again, one section is fixed on the other end of tautness meter, through pulley, is fixed on manual gear take-up device by the other end of steel wire.The position of adjustment pulley, makes steel wire to be measured vertical, rotates take-up device, make Wire pulling to be measured, record the reading of tautness meter.Then adjust optical lever arrangement, make the laser generator level be positioned in optical lever.The height of adjustment reference laser generator, makes two laser generators be in sustained height, and makes the diameter sent be that the laser of 0.5mm shines on the uniform height of the ruler vertically placed.Adjustment CCD camera lens, makes it aim at the ruler vertically placed, and clearly reading laser generator impinges upon the position on ruler.By computer applications software, CCD camera lens photo shows in computer, and can read data.Rotate take-up device, by applying different tensile force fs to steel wire, the deformation quantity Δ L of steel wire to be measured is read from computing machine, steel wire diameter d is measured again with micrometer caliper, the former long L of steel wire (distance of steel wire head fixed plate and optical lever tie point on a steel cord) is measured with meter ruler, be entered in software, system can obtain the Young modulus of steel wire to be measured automatically.
Owing to adopting such scheme, following remarkable result can be received:
Tradition Young modulus needs to use many counterweights when measuring, and be not easy to management and also take large quantity space, the present invention reads pulling force by tautness meter, saves space and reading duration;
Owing to traditional telescope, mirror, counterweight being eliminated, add laser generator, CCD camera lens, thus this maximum operation problem of the reflection image of the scale in measurement difficulty searching is thoroughly eliminated.
Computer monitor and take-up device are put together, and operator neither needs to run back and forth, turn eliminates the crowded of laboratory.
By computer image process, the data of reading are more accurate; By program design, avoid a large amount of computation process, improve the accuracy of data, decrease error.

Embodiment
The present embodiment modulus measurer has a few part below to form:
1, intelligent Young modulus support:
Intelligent Young modulus have employed stand type support, has the steel plate of two vertical steel and three pieces of horizontal positioned to form.Wherein the steel plate strip at top is fluted, is used for placing steel wire head fixed plate; Middle steel plate is used for placing CCD camera lens and optical lever arrangement, and steel plate central aperture, allows the chain-wales of steel wire to be measured and optical lever pass from centre; The steel plate of bottom is with slideway, and pulley bracket can be free to slide on slideway, locks pulley bracket by set nut.
2, steel wire head fixed plate
Steel wire head fixed plate is used for fixing steel wire to be measured.
3, optical lever arrangement
The laser generator of a horizontal positioned is contained in one end of three foot plates, and three toe P1, P2, P3 form isosceles triangle.The vertical line of P1 to P2P3 is long is Z, and with front foot P2, P3 for luminous point rotating shaft, if small change occurs the height of metapedes P1, the light that laser generator is launched is reflected on ruler as lever instruction through longer light path.
4, laser generator:
Intelligent modulus measurer has two laser generators, reference laser generator and the laser generator be positioned in optical lever.The front end of laser generator is the cover plate of 0.5mm with aperture, ensures that the light that laser generator is launched is thinner, easily on ruler, reads data accurately.During measurement, the height of adjustment two laser generators, makes it be in sustained height.When applying pulling force to wire rope, reference laser generator maintains static, and the laser generator be positioned in optical lever has slight movement, so just can read the amount of movement of light on ruler.
5, pulley gear
This device is made up of pulley, pulley bracket, adjustment screw, lock screw etc.By adjustment screw, the height of pulley can be adjusted; By lock screw, the horizontal level of pulley bracket can be adjusted.When unclamping lock screw, pulley bracket can horizontal slip in optical lever, when sliding into suitable position, fixes pulley bracket by lock screw.
6, steel wire tensioner
Steel wire tensioner is made up of pinion rotation handle, gear, gear stand and gear self-locking mechanism.When applying pulling force, by pinion rotation handle transmitting gear.When pulling force is suitable, unclamp turning handle, gear self-locking mechanism can automatically lock the position of gear, keeps tensions constant.
7, CCD camera lens
CCD camera lens is fixed, and it aims at ruler, can be read the data on ruler by computer easily.
8, ruler
After applying pulling force, read the side-play amount of laser by ruler.
9, ruler latch mechanism
By ruler latch mechanism, the height of ruler on support rack can be regulated and holding position is fixed.
10, ruler support
Be used for fixing ruler.
When carrying out Young modulus and measuring, steel wire head fixed plate is fixed on the top of support by the fishbolt carried, pulley is fixed on the bottom of support by adjustable apparatus, getting a segment length is stent length 0.5-0.7 steel wire to be measured doubly, in the disconnected knotting of one, the other end is connected on the tautness meter of verification through optical lever arrangement.Get the steel wire of a segment length about 1.5 meters again, its one end is fixed on the other end of tautness meter, through pulley, is fixed on manual take-up device by the other end of steel wire.The position of adjustment pulley, makes steel wire to be measured vertical, rotates take-up device, make Wire pulling to be measured, record the reading of tautness meter.Then adjust optical lever arrangement, make the laser generator level be positioned in optical lever.The height of adjustment reference laser generator, makes two laser generators be in sustained height, and the diameter making it send is that the laser of 0.5mm shines on the uniform height of the ruler vertically placed.Adjustment CCD camera lens, makes it aim at the ruler vertically placed.The position that laser generator impinges upon the point above ruler can be read clearly by computer.Rotate take-up device, by applying different tensile force fs to steel wire, the laser being positioned at the laser generator injection in optical lever is moved on ruler, according to the position of reference point and be positioned at the deformation quantity Δ L that the laser that optical lever the is launched position measurement impinged upon on ruler goes out steel wire to be measured, steel wire diameter d is measured again with micrometer caliper, the former long L of steel wire (distance of steel wire head fixed plate and optical lever tie point on a steel cord) is measured with meter ruler, be entered in software, system can obtain the Young modulus of steel wire to be measured automatically.
