Abstract
The utility model provides a measuring device for metal wire Young modulus. The measuring device comprises a device support (1), a base (2), a fastening piece 1 (3), a fastening piece 2 (4), a digital readout module (5), an optical fiber displacement sensor (6), light reflecting aluminum foil (7), and a top metal wire clamp (8). Due to the fact that the optical fiber displacement sensor is introduced in measurement of micrometric displacement in Young modulus and results of measurement of micrometric displacement are directly obtained through the digital readout module, the measurement of the micrometric displacement in the Young modulus becomes simple and easy to operate.
Description
Technical field
The utility model belongs to the physical experiment apparatus field, the measurement mechanism of a kind of tinsel Young modulus of more specifically saying so.
Background technology
During traditional Young modulus is measured, use pulling method to measure Young modulus wiry, wire end is hung up counterweight and surveys its elongation with the optical lever amplifying method, experiment is difficult to adjusting, more time-consuming and precision is relatively poor.The design introduces optical fibre displacement sensor and output voltage has been carried out digitized processing and demonstration in the tinsel elongation microdisplacement measurement of Young modulus experiment, has directly obtained the microdisplacement measurement result, makes simple that microdisplacement measurement becomes in the Young modulus.
Summary of the invention
In the measurement that improves the tinsel Young modulus, the difficult shortcoming of measuring of small elongation, the utility model provides a kind of simple to operate, easy digital display modulus measurer of measurement.
A kind of digital display modulus measurer; Comprise equipment supporter (1), base (2), securing member 1 (3), securing member 2 (4), digital display module (5), optical fibre displacement sensor (6), reflective aluminium foil (7), top metal silk folder (8); Above-mentioned digital display module (5) and ray displacement sensor (6) are fixed on the securing member 1 (3), and securing member 1 (3), securing member 2 (4) front ends have small circle ring, and there is screw the rear end; Can move up and down along the montant of equipment supporter (1), and be fixed on the montant by screw tightening.
Description of drawings
Fig. 1 is the structural representation of the utility model
Fig. 2 is the circuit theory diagrams of the digital display module of the utility model
Among the figure: equipment supporter (1), base (2), securing member 1 (3), securing member 2 (4), digital display module (5), optical fibre displacement sensor (6), reflective aluminium foil (7), top metal silk folder (8)
Embodiment
Specify below in conjunction with the embodiment of accompanying drawing the utility model.
Like Fig. 1; The digital display modulus measurer is made up of equipment supporter (1), base (2), securing member 1 (3), securing member 2 (4), digital display module (5), optical fibre displacement sensor (6), reflective aluminium foil (7), top metal silk folder (8); Above-mentioned digital display module (5) and ray displacement sensor (6) are fixed on the securing member 1 (3), and securing member 1 (3), securing member 2 (4) front ends have small circle ring, and there is screw the rear end; Can move up and down along the montant of equipment supporter (1), and be fixed on the montant by screw tightening.
Tinsel to be measured utilizes top metal silk folder (8) to clamp, and it is sagging to pass the aperture of securing member 1 (3), securing member 2 (4) front ends, and reflective aluminium foil (7) is fixed on tinsel bottom and vertical with tinsel; Parallel with optical fibre displacement sensor (6) end face, securing member 1 (3) is fixed on the montant correct position avoids tinsel to rock, when tinsel is not hung counterweight; Regulating securing member 2 (4) makes optical fibre displacement sensor (6) and reflective aluminium foil (7) be close to; Fixation fastener 2 (4) then, and digital display module this moment (5) is shown as zero, along with counterweight increases; The tinsel elongation increases; Displacement between optical fibre displacement sensor (6) and the reflective aluminium foil (7) increases, and digital display module (5) display digit strengthens, and digital display module (5) directly demonstrates the displacement data between optical fibre displacement sensor (6) and the reflective aluminium foil (7).
Digital display module (5) is made up of sensor interface, modulate circuit, AD converter, single-chip microcomputer and Liquid Crystal Module.Optical fibre displacement sensor converts displacement to little electric weight; Modulate circuit is converted into the d. c. voltage signal of 0V to 5V; Utilize high-precision AD converter to convert digital signal to again; Single-chip microcomputer collects this digital signal after overcorrect is handled, and utilizes Liquid Crystal Module to show the Displacement Measurement data at last.
Claims (1)
1. digital display modulus measurer; It is characterized in that: comprise equipment supporter (1), base (2), securing member 1 (3), securing member 2 (4), digital display module (5), optical fibre displacement sensor (6), reflective aluminium foil (7), top metal silk folder (8); Above-mentioned digital display module (5) and ray displacement sensor (6) are fixed on the securing member 1 (3); Securing member 1 (3), securing member 2 (4) front ends have small circle ring; There is screw the rear end, can move up and down along the montant of equipment supporter (1), and is fixed on the montant by screw tightening.
