Description

One kind measures accurately butterfly tens(i)ometer

Technical field

Reinforcing bar elasticity modulus detection technique field is the utility model is related to, more particularly to accurately butterfly is extended for a kind of measurement Instrument.

Background technology

Butterfly tens(i)ometer is mainly used to some mechanical mechanics properties of measuring metallic materials and some nonmetallic materials, butterfly Tens(i)ometer can coordinate universal testing machine to measure the displacement of material or strain, can try to achieve the elasticity modulus of material by conversion and bend Intensity is taken, and the Deformation control of reinforced bar stretching technique, measurement analysis and control can be used for.

Butterfly tens(i)ometer on the market mainly includes sensing crushed element, transmitting portions and indicating section at present, described Sensing deformation part mainly includes contradicting the upper edge of a knife on object to be measured and contradicts the lower edge of a knife on object to be measured, described The lower edge of a knife can be rotated around itself midpoint, and the object deformation quantity to be measured of lower edge of a knife measurement, which is delivered on scale, to be shown.Its deficiency Part is：The upper edge of a knife, the transverse shifting of the lower edge of a knife are adjusted by the regulating device being fixed on mark post, described to adjust dress The stent including being fixed on a mark post is put, the stent is equipped with a guide post, compression spring is socketed with the guide post, compression spring Free end is contradicted on another mark post, which is difficult to make the upper edge of a knife of the lower edge of a knife and homonymy translate and contradict treating Survey on object, therefore operating difficulties, and influence measurement result.

Utility model content

The purpose of this utility model is in view of the deficienciess of the prior art, the lower edge of a knife of the i.e. upper edge of a knife and homonymy is difficult to put down Move, be difficult to all contradict on object to be measured, influence measurement result, there is provided a kind of lower edge of a knife that can make the edge of a knife and homonymy is put down Move, and ensure that the upper edge of a knife contradicts on object to be measured always with the lower edge of a knife, so as to efficiently return to zero and measure deformation quantity to scale Butterfly tens(i)ometer.

One kind measurement accurately butterfly tens(i)ometer, including pedestal, the pedestal is equipped with horizontal guide rod, on the pedestal The through hole passed through for object under test is offered, a pair of slide being oppositely arranged is socketed with the guide rod, is set on the pedestal There is a pair of of propulsion device, each propulsion device includes the round bar set along guide rod length direction, pressure is socketed with the round bar Contracting spring, the one end for compressing spring are contradicted on pedestal, and the other end is contradicted on corresponding slide, and the slide, which is equipped with, to be used In the upper edge of a knife of the conflict on object to be measured, the lower knife for measuring object deformation quantity to be measured and display object deformation to be measured The scale of amount, the center of gravity of the lower knife are hinged on slide, and one end of lower knife is contradicted on object to be measured, and the other end contradicts On the contact of scale.

During utility model works, object to be measured is passed through through hole by operating personnel first, and universal testing machine is by object to be measured Both ends clamp, then unclamp each propulsion device, each propulsion device promotes slide to be moved along guide rod respectively, slide make the edge of a knife and One end of lower knife is contradicted on object to be measured, then is returned to zero to scale, is started universal testing machine, is subject to object both ends to be measured The pulling force of quota, object to be measured deform upon, and the amount deformed upon is shown from scale, and operating personnel are according to the reading of scale Number, the elasticity modulus of object to be measured is calculated using formula.

Compared with prior art, the beneficial effects of the utility model are：Since guide rod is engaged with slide, slide can be along leading Bar translates, the upper edge of a knife installed on slide and lower knife integral translation, and due to the presence of propulsion device, the upper edge of a knife and the lower edge of a knife It can all the time contradict on object to be measured, consequently facilitating measured value is treated in scale zeroing or reading, therefore shorten the mobile upper edge of a knife with The time of knife and the time to amesdial zeroing, operating process is simplified, substantially increases object elasticity modulus to be measured Detection efficiency.

In order to ensure scale measures the accuracy of object deformation quantity to be measured, avoid pedestal uneven to rotatably lower knife one A initial offset, so as to influence the measured value of scale, the pedestal, which is equipped with, is used for measurement in the same horizontal line Level meter, multiple adjustable support legs for adjusting foundation level degree are screwed with the pedestal.

In order to which the structure for measuring lower knife is accurately reacted on corresponding scale, the lower knife with scale contact Part is equipped with the protrusion easy to be touched with scale contact.

In order to more intuitively see the deformation quantity of determinand part, the slide is equipped with to be stretched for measuring object to be measured The mark post of amount, the free end of the mark post are connected with the edge of a knife.

In order to adjust vertically moving for the upper edge of a knife, along mark post length direction equipped with threaded hole separately, the upper edge of a knife It is fixed in through hand-screw on threaded hole.
