Description
Technical field
The present invention relates to the modulus measurer in Experiment of College Physics, relate in particular to a kind of intelligent modulus measurer that support is vertical placement of measuring.
Background technology
Known at present, the steel wire of usining is all non intelligent as the modulus measurer of measured object, the shortcoming of this vertical drawing structure is to need a lot of counterweights, deposit cumbersome, careless manipulation, easily hurts operator's foot on counterweight Crater face, 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 between telescope and measurement bay, to run, and causes laboratory confusion crowded.
Summary of the invention
The object of the invention is provides 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 to the top of support by the fishbolt carrying, pulley is fixed on to 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 through verification through optical lever device.The steel wire of getting again 1.5 meters of left and right of segment length, one section is fixed on the other end of tautness meter, through pulley, the other end of steel wire is fixed on manual gear take-up device.The position of adjusting pulley, makes steel wire to be measured vertical, rotates take-up device, makes Wire pulling to be measured, records the reading of tautness meter.Then adjust optical lever device, make to be positioned at the laser generator level in optical lever.The height of adjusting reference laser generator, makes two laser generators in sustained height, and the diameter that makes the to send laser that is 0.5mm shines on the unified height of ruler of vertical placement.Adjust CCD camera lens, make it aim at the ruler of vertically placing, clearly read laser generator and impinge upon the position on ruler.By computer applications software, CCD camera lens photo shows in computer, and can reading out data.Rotate take-up device, by steel wire being applied to different tensile force fs, from computing machine, read the deformation quantity Δ L of steel wire to be measured, with micrometer caliper, measure steel wire diameter d again, with meter ruler, measure the former long L of steel wire (distance of steel wire head fixed plate and the optical lever tie point on wire rope), be entered in software, system can be obtained the Young modulus of steel wire to be measured automatically.
Owing to adopting such scheme, can receive following remarkable result:
When tradition Young modulus is measured, need to use many counterweights, be not easy to management and also take large quantity space, the present invention reads pulling force by tautness meter, has saved space and reading duration;
Due to traditional telescope, mirror, counterweight have been cancelled, increased laser generator, CCD camera lens, thereby difficult this maximum operation problem of finding of reflection image of the scale in measurement is thoroughly eliminated.
Computer monitor and take-up device are put together, and operator neither needs to run back and forth, has eliminated again the crowded of laboratory.
By computer image, process, the data that read are more accurate; By program design, avoided a large amount of computation process, improved the accuracy of data, reduced error.

Embodiment
The present embodiment modulus measurer has several parts below to form:
1, intelligent Young modulus support:
Intelligent Young modulus has adopted stand type support, has the steel plate of two vertical steel and three 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 device, and perforate in the middle of steel plate, 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, by set nut, locks pulley bracket.
2, steel wire head fixed plate
Steel wire head fixed plate is used for fixing steel wire to be measured.
3, optical lever device
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 length of P1 to P2P3 is Z, and take front foot P2, P3 as luminous point rotating shaft, if small variation occurs the height of metapedes P1, through longer light path, as lever, indication is reflected on ruler the light that laser generator is launched.
4, laser generator:
Intelligent modulus measurer has two laser generators, reference laser generator and be positioned at the laser generator in optical lever.The cover plate that the front end of laser generator is 0.5mm with aperture, guarantees that the light that laser generator launches is thinner, easily reading out data accurately on ruler.During measurement, adjust the height of two laser generators, make it in sustained height.When wire rope is applied to pulling force, reference laser generator maintains static, and the laser generator being 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 to consist of pulley, pulley bracket, adjustment screw, lock screw etc.By adjusting screw, can adjust the height of pulley; By lock screw, can adjust the horizontal level of pulley bracket.When unclamping lock screw, pulley bracket can horizontal slip in optical lever, while sliding into suitable position, by lock screw, fixes pulley bracket.
6, steel wire tensioner
Steel wire tensioner is to consist of gear turning handle, gear, gear stand and gear self-locking mechanism.While applying pulling force, by gear turning handle transmitting gear.When pulling force is suitable, unclamp turning handle, gear self-locking mechanism can automatically lock the position of gear, keeps pulling force constant.
7, CCD camera lens
CCD camera lens is fixed, and it aims at ruler, by computer, can read easily the data on ruler.
8, ruler
After applying pulling force, by ruler, read the side-play amount of laser.
9, ruler latch mechanism
By ruler latch mechanism, can regulate height the holding position of ruler on support rack to fix.
10, ruler support
Be used for fixing ruler.
When carrying out Young modulus measurement, steel wire head fixed plate is fixed on to the top of support by the fishbolt carrying, pulley is fixed on to 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 through verification through optical lever device.The steel wire of getting again 1.5 meters of left and right of segment length, its one end is fixed on the other end of tautness meter, through pulley, the other end of steel wire is fixed on manual take-up device.The position of adjusting pulley, makes steel wire to be measured vertical, rotates take-up device, makes Wire pulling to be measured, records the reading of tautness meter.Then adjust optical lever device, make to be positioned at the laser generator level in optical lever.The height of adjusting reference laser generator, makes two laser generators in sustained height, and laser that its diameter sending is 0.5mm is shone on the unified height of ruler of vertical placement.Adjust CCD camera lens, make it aim at the ruler of vertically placing.By computer, can read clearly the position that laser generator impinges upon the point above ruler.Rotate take-up device, by steel wire being applied to different tensile force fs, the laser that is positioned at the laser generator ejaculation in optical lever is moved on ruler, according to the position of reference point and be positioned at the laser of launching in optical lever and impinge upon the deformation quantity Δ L that position measurement on ruler goes out steel wire to be measured, with micrometer caliper, measure steel wire diameter d again, with meter ruler, measure the former long L of steel wire (distance of steel wire head fixed plate and the optical lever tie point on wire rope), be entered in software, system can be obtained the Young modulus of steel wire to be measured automatically.
