The strain value of the elastic body is measured with the digital meter that is mounted in the circle center and is displayed with figures. The utility model has the advantages of digisplay, high precision, dynamic measurement, measurement by magnification and peak holding and is draw-able and stress-able. The utility model can be connected with computer for digital processing and printing. The utility model is mainly used for static or dynamic measurement of pull strength and stress of objects, machinery and vehicles as well as scales of non-trade settlement.
Description
Technical field
Digital circular tension compression bidirectional dynamometer belongs to the dynamometry field of measuring techniques, be mainly used in pulling force and pressure such as measuring various objects, machinery, car and boat, be commonly used to the power value of certificate test machine, be used to measure the pulling force of electric wire, cable, the bending force of electric pole etc. in power industry, be used to stress that gives stress members etc. in building trade, also can be used as the scale of non-trade settlement.
Technical background
Known tubular helical spring type tautness meter can only be measured pulling force and can not gaging pressure.In addition, measure numerical value and indicated on scale by pointer, accuracy is low, generally is up to ± 1%, and can only be used for static state and can not be used for kinetic measurement.
Summary of the invention
The purpose of this utility model is, provides a kind of simple in structure, can survey pulling force and can measuring pressure, by numeral show, accuracy is higher than ± 0.5%, numerical expression circle tension compression bidirectional dynamometer static and that dynamically all can be suitable for.
The utility model solves technical scheme that its technical matters adopts: a kind of digital circular tension compression bidirectional dynamometer that is used to measure pulling force or pressure, comprise: draw ring (1), elastic body (2), digital watch (3), gland (4), dial framework (5), base (6) and drag hook (7), elastic body (2) is circular, by orthogonal two mechanical axis in the center of circle, be respectively and pull to axle and press to axle, its x-x ' is a pressure axis, y-y ' is a thrust axis, because elastic body is circular, the tension and compression diaxon is mutually the right angle, no matter tension or pressurized, deformation direction is identical.Distortion after the dynamometer elastic body is stressed is measured by digital watch, and it can directly show the shift value of distortion, also can by output to computing machine through data processing shift length value converting to force value.
The beneficial effects of the utility model are:
1. the equal energy measurement of tension compression bidirectional.
2. the high indicating value of measuring accuracy is shown by numeral, and can be connected with computing machine carry out that data processing, result are printed, programmed control or the like.
3. also have advantages such as quick measurement, measuring memory, kinetic measurement and measurement by magnification.
Description of drawings
Accompanying drawing has been described an embodiment of the present utility model.1, draw ring, 2, elastic body, 3, digital watch, 4, gland, 5, dial framework, 6, base, 7, drag hook.
Embodiment
Dynamometer elastic body (2) is designed to circle, gland (4) is connected respectively with elastic body (2) y-y ' axle two ends with base (6), digital watch (3) is fixed tightly in the link of the base (6) of elastic body (2) by dial framework (5), and be installed in the center of elastic body (2), and the gauge head of digital watch (3) withstands on the inside surface of elastic body (2) of the other end, when pressure acts on gland (4) and base (6), elastic body (2) y-y ' direction of principal axis is crushed, and x-x ' direction of principal axis is extended, according to the Hooke theorem: in elastic range, stress and strain is proportional, and pressure is big more, dependent variable is also big more, and the pressure-strain value is by showing on the digital display meter.And when making tension measurement, pulling force acts on drag hook (7) and the draw ring (1), and same elastic body (2) x-x ' direction of principal axis is elongated, and y-y ' axle shortens, and the big more dependent variable of pulling force is many more, and the tension strain value is by showing on the digital watch (3).Digital watch (3) directly shows shift length value (mm), by calculating or must the value of exerting oneself by the stress-strain curve table.Also can be connected with computing machine and carry out data processing shift length value converting to force value by output interface.Also can carry out programmed control and print automatically, have characteristics such as quick measurement, measuring memory, kinetic measurement and measurement by magnification.
The every technical indicator of the utility model meets the requirement of regulation among national standard JJG144-1992 " standard dynamometer " and the JJG455-2000 " work dynamometer " fully.
Claims (2)
1. digital circular tension compression bidirectional dynamometer that is used to measure pulling force or pressure, comprise: draw ring (1), elastic body (2), digital watch (3), gland (4), dial framework (5), base (6) and drag hook (7), it is characterized in that: elastic body (2) is for circular, by orthogonal two mechanical axis in the center of circle, be respectively and pull to axle and press to axle.
2. according to the described digital circular tension compression bidirectional dynamometer of claim 1, its feature also is: the measurement indicating value is a digital wash.
