Abstract
The invention discloses an anti-shaking Young modulus tester. The anti-shaking Young modulus tester comprises a chassis, a bolt and a weight tray, wherein three fixing plates with same structure are fixedly arranged on the upper surface of the chassis; the three fixing plates are tile-shaped, and arranged on concentric annuluses with a vertical centre shaft of the chassis as a central rotary shaft; an angle of 120 degrees is formed between adjacent horizontal central shafts of the three fixing plates; second threaded holes are arranged above the horizontal central shafts of the fixing plates close to an upper side surface; the horizontal central shafts of the three second threaded holes and a vertical central shaft of the chassis are crossed at one point; the bolt is adaptive to the second threaded hole; weight trays are inverted bulge-shaped, and first threaded holes are arranged in a centre of the upper side surface of the weight tray. The anti-shaking Young modulus tester has a simple structure and is convenience in use, can effectively overcome problems that a steel wire to be tested shakes to interfere observation and reading in a process of increasing and reducing weights during an experiment.
Description
Technical field
The invention belongs to the physical experiment apparatus field, particularly a kind of anti-rock measure apparatus of youngs modulus.
Background technology
The measurement of Young modulus is an important experiment in the Experiment of College Physics.Traditional La Shenfa measures the metal Young's modules instrument and adopts the optical lever principle, by the increase and decrease counterweight, small elongation wiry is passed through the specular light lever amplification, and by placing telescope and scale at a distance to observe.In the experimentation, troubling problem is: steel wire to be measured rocks disturbance-observer, reading in the process of increase and decrease counterweight.
?
Summary of the invention
In order to overcome in the process of increase and decrease counterweight, the problem that steel wire to be measured rocks the present invention is to provide a kind of anti-rock measure apparatus of youngs modulus, and it can solve the problem in the reality.
The technical solution adopted for the present invention to solve the technical problems is: the anti-rock measure apparatus of youngs modulus comprises the chassis, screw and weight tray, described chassis upper surface is fixedly installed three stators that structure is the same, three stators are tile shape, be positioned on the donut of rotating shaft centered by the vertical central shaft in chassis, be mutually 120 degree between the adjacent level central shaft of three stators, directly over the stator horizontal middle spindle, be provided with the second threaded hole near the upper side place, the vertical central shaft in the horizontal middle spindle of three the second threaded holes and chassis meets at a bit, described screw and the second threaded hole are adaptive, described weight tray is for falling " protruding " body, and its upper side center is provided with the first threaded hole.
During use, the chassis is fixed on the base of measure apparatus of youngs modulus, fix respectively two vertical bars by two circular holes, to link up with weight tray by the first threaded hole and to be fixedly connected with, install again the miscellaneous part of instrument, hook is suspended to the tinsel lower end, by changing the position of length adjustment weight tray wiry, make the downside of weight tray slightly be lower than the horizontal middle spindle of the second threaded hole, rotate respectively three screws, make its head almost by the face of cylinder of weight tray, can add counterweight on the upper side of weight tray and begin to test.Because weight tray is limited in surface level in the very little scope of activities, in the process of increase and decrease counterweight, steel wire to be measured has also just rocked hardly.
The present invention is simple in structure, and is easy to use, and in the process of increase and decrease counterweight, steel wire to be measured rocks in the time of effectively overcoming experiment, and the problem of disturbance-observer, reading has improved measuring accuracy and efficient.

Embodiment
Below in conjunction with the detailed embodiments of the present invention of accompanying drawing:
Such as Fig. 1, Fig. 2 and shown in Figure 3, anti-rock measure apparatus of youngs modulus of the present invention comprises chassis 1, screw 5 and weight tray 3, described chassis 1 upper surface is fixedly installed three stators 2 that structure is the same, three stators 2 are tile shape, be positioned on the donut of rotating shaft centered by the 1 vertical central shaft of chassis, be mutually 120 degree between the adjacent level central shaft of three stators 2, directly over stator 2 horizontal middle spindles, be provided with the second threaded hole 21 near the upper side place, the horizontal middle spindle of three the second threaded holes 21 and chassis 1 vertical central shaft meet at a bit, described screw 5 and the second threaded hole 21 are adaptive, described weight tray 3 is for falling " protruding " body, and its upper side center is provided with the first threaded hole 4.
During use, chassis 1 is fixed on the base 31 of measure apparatus of youngs modulus, fix respectively two vertical bars 32 by two circular holes 6, to link up with 33 by the first threaded hole 4 is fixedly connected with weight tray 3, install again the miscellaneous part of instrument, to link up with 33 and be suspended to the tinsel lower end, by changing the position of length adjustment weight tray 3 wiry, make the downside of weight tray 3 slightly be lower than the horizontal middle spindle of the second threaded hole 21, rotate respectively three screws 5, make its head almost by the face of cylinder of weight tray 3, can add counterweight on the upper side of weight tray 3 and begin to test.Because weight tray is limited in surface level in the very little scope of activities, in the process of increase and decrease counterweight, steel wire to be measured has also just rocked hardly.
