Abstract
The invention discloses an electric appliance reed elasticity value measuring device and an electric appliance reed elasticity value measuring method. The measuring device comprises a compression column, a compression piece and a pad column, wherein the compression piece is fixed on the compression column through a compression screw; the compression column comprises a connecting plate which is matched with the upper compression plate of a spring tensile and compression testing machine; the connecting plate is connected with the upper compression plate through a fastening device; the pad column is arranged on the lower compression plate of the spring tensile and compression testing machine; the pad column is provided with a clamp groove which is used for clamping measured reed parts; the compression piece comprises a compression head for compressing the electric appliance reed; the shape of the compression head is adaptive to a contact matched with the electric appliance reed; and the electric appliance reed elasticity value measuring method is that the testing machine compression plates are moved up and down to drive the compression column to compress the reed to stimulate working deformation of the electric appliance reed, so that the elasticity value that an abnormal-shaped reed deforms to specified amount can be read from a dial plate of the spring tensile and compression testing machine, therefore, the electric appliance reed elasticity value measuring device and measuring method are convenient to operate and good in repeatability, and can be used for accurately measuring the elasticity value of the reed; and the part quality is guaranteed.
Description
Technical field
The invention belongs to elastic force detection technique field, be specifically related to a kind of electrical equipment reed value of elastic measurement mechanism and measuring method thereof.
Background technology
In product design, running into appliance contact use contact formula mode of communicating, for ensureing that electrical connection contacts reliable and possesses certain reliability, needing to control the elasticity force value of electrical equipment contact.Taked the qualitative elastic force to electrical equipment reed of the mode of feel and range estimation to control in the past, the control of this method is more extensive, accurately cannot measure value of elastic, can not judge the lasting resistance to pressure of reed simultaneously, control inaccurate to the value of elastic of device reed, the quality of such part can not be ensured.
Summary of the invention
For solving the above-mentioned defect that prior art exists, the object of the present invention is to provide a kind of structure simple, can Accurate Measurement reed value of elastic, ensure the electrical equipment reed value of elastic measurement mechanism of part quality.
Another object of the present invention is to the measuring method that a kind of electrical equipment reed value of elastic is provided, easy to operate, favorable reproducibility.
For achieving the above object, the technical solution used in the present invention is: this electrical equipment reed value of elastic measurement mechanism, it is characterized in that: by compression leg, compressing tablet and pad post are formed, described compressing tablet is fixed on compression leg by housing screw, described compression leg has the terminal pad matched with the top board of spring tension and compression testing machine, described terminal pad is connected with top board by fastener, described pad post is placed on the lower platen of spring tension and compression testing machine, pad post is provided with the draw-in groove clamping tested reed part, described compressing tablet has the pressure head of pressing electrical equipment reed, the contact that the shape of described pressure head coordinates with electrical equipment reed adapts.
The number of described pressure head is identical with the number of electrical equipment reed.
Draw-in groove on described pad post is 2.
A kind of electrical equipment reed value of elastic measuring method, is characterized in that operating in the steps below:
1). electrical equipment reed part is installed in the draw-in groove of pad post;
2). rotate pad post and make the reed of part keep corresponding parallel with frock compressing tablet direction;
3). drawing-pressing spring testing machine operating grip, can obtain reed value of elastic.
Adopt the beneficial effect of above-mentioned technical scheme: the compression leg screw of this electrical equipment reed value of elastic measurement mechanism is installed on the top board of spring tension and compression testing machine, electrical equipment reed part is put on pad post, rotate pad post makes the reed of part keep corresponding parallel with frock compressing tablet direction simultaneously, manipulation drawing-pressing spring testing machine presses making leaf spring by compressing tablet, because the shape of pressure head is identical with the contact that electrical equipment reed coordinates, thus simulate the actual working state of electrical equipment reed, move up and down testing machine pressing plate and drive the distortion of compression leg compressing reed analog operation, the value of elastic that special-shaped reed is deformed to specified amount can be read on testing machine dial plate.Because the number of compressing tablet end pressure head is identical with the number of electrical equipment reed, be pressed onto the number of reed according to compressing tablet, can record the elastic force of different spring combination and comprehensive reed, reach control apparatus reed characteristic value of elastic, meet design requirement ability.By practice, effect is better, and the elastic force can shifting similar structures onto is measured and controls, and conscientiously ensures part quality.This electrical equipment reed value of elastic measuring method is simple, and measurement data is accurately stable, measures and has reappearance.
