Description
Technical field
The utility model relates to a kind of experimental pressure machine.
Background technology
The experimental pressure machine is called the compressive strength test machine again, is a kind of of Material Testing Machine.The experimental pressure machine is mainly used in the compressive strength that detects various solid materials, confirms through detected intensity whether product reaches the strength grade production standard.
The important technological parameters of experimental pressure machine is a maximum test force; Be that the tester physical efficiency is born great pressure and just can be out of shape or cracked; Usually represent pressure with kgf, the newton N of unit, thousand Ns of KN (also useful " kilogram KG, ton T, kPa KP " representes).Test specification generally is to be that the upper limit is backward compatible with the maximum test force.Pressue device generally adopts hydraulic pressure or air pressure pressurization.
The material compressive strength of different industries is different; Therefore the measurement range of experimental pressure machine is also different; Though test specification is to be that the upper limit is backward compatible with the maximum test force, to go to test resistance to compression with the equipment of wide range and require very low object, the degree of accuracy of test findings just cannot say for sure card; Just, can't read reading as the weight of removing to claim 1 pin with platform scale.
Traditional displacement transducer can not reach and satisfy precision and outdoor use simultaneously.
The utility model content
The purpose of the utility model is to provide a kind of a kind of experimental pressure machine that is fit to outdoor transportation and operation.
A kind of sensor satisfies the experimental pressure machine of precision and outdoor use simultaneously; Comprise some some pressure transducers, magnetostrictive displacement sensor, data processing unit, solenoid valves that are used for sensing testee pressure condition; Some pressure transducers, magnetostrictive displacement sensor connect data processing unit respectively, and said data processing unit connects solenoid valve.
The experimental pressure machine also comprises touch-screen, and said touch-screen connects data processing unit.
Said pressure transducer comprises hydraulic pressure sensor and stress pressure sensor.
The experimental pressure machine also comprises notebook computer, and said notebook computer connects data processing unit.
Magnetostrictive displacement sensor is accurately measured the actual displacement value of product to be detected in the absolute position of detected activity magnet ring through the contactless observation and control technology in inside; Because magnetostrictive displacement sensor has above-mentioned advantage; Therefore; Use this sensor can realize being fit to outdoor various environment and use, and can also satisfy the requirement of precision.
Description of drawings
Fig. 1 is the theory structure synoptic diagram of experimental pressure machine.
Embodiment
A kind of sensor satisfies the experimental pressure machine of precision and outdoor use simultaneously, comprises precompressed mechanism, automatically controlled part and hydrostatic control part.Precompressed mechanism can comprise and presses down crossbeam, first guide upright post and second guide upright post.Testee is placed on the below that presses down crossbeam, presses down through pressing down crossbeam, carries out pressure experiment to testee to apply power.The electric control part branch comprises some some pressure transducers that are used for sensing testee pressure condition and magnetostrictive displacement sensor 3, data processing unit 5, solenoid valve 7; Some pressure transducers, magnetostrictive displacement sensor 3 connect data processing unit 5 respectively, and data processing unit 5 connects solenoid valve 7.That is, various pressure transducers and displacement transducer pressure parameter and the displacement parameter that will press down process is sent to data processing unit and handles.The opening and closing that press down can act on the hydrostatic control part through solenoid valve through acting on solenoid valve, reach the motion that presses down crossbeam etc. with this.
Magnetostrictive displacement sensor is accurately measured the actual displacement value of product to be detected in the absolute position of detected activity magnet ring through inside contactless observation and control technology; The high precision of this sensor and high reliability have been widely used in the thousands of real case.Do not contact owing to have directly with sensitive element, so sensor can be applicable in the most evil bad industrial environment, be not subject to the influence of oil stain, solution, dust or other pollution as the movable magnet ring of confirming the position.In addition, sensor has adopted high-tech material and advanced electronic processing technology, thereby it can be applied in the environment of high temperature, high pressure and high vibration.Sensor output signal is the absolute displacement value, even power interruption, reclosing, data can not lost yet, and more need not make zero again.Because sensitive element is noncontact,, can improve the reliability and the serviceable life of detection widely even if continuous duplicate detection can not cause any wearing and tearing to sensor yet.
Magnetostrictive displacement sensor 3 utilizes magnetostriction principle, comes measuring position exactly through strain-pulse signal of the crossing generation of two different magnetic fields.Measuring sensor is a waveguide, and the sensitive element in the waveguide is processed by special magnetostriction materials.Measuring process is to produce current impulse in the electronic room by sensor; This current impulse is transmitted in waveguide, thereby outside waveguide, produces a circumference magnetic field, when intersect in the magnetic field that produces with the movable magnet ring that is enclosed within on the waveguide as change in location when this magnetic field; Because magnetostrictive effect; Can produce a strain mechanical wave pulse signal in the waveguide, this strain mechanical wave pulse signal transmits with fixing speed of sound, and is detected by electronic room very soon.Because transmission time and the movable magnet ring of this strain mechanical wave pulse signal in waveguide is directly proportional with distance between the electronic room, through Measuring Time, just can highly precisely confirm this distance.Because the output signal is a real absolute value, rather than signal ratio or processing and amplifying, so there is not the situation of signal drift or variate, more need not regularly heavily to mark.
Because magnetostrictive displacement sensor has above-mentioned advantage, therefore, use this sensor can realize being fit to outdoor various environment and use, and can also satisfy the requirement of precision.
This experimental pressure machine also comprises touch-screen 6, and said touch-screen 6 connects data processing unit 5.The user just can operate through touch-screen.
Said pressure transducer comprises hydraulic pressure sensor 1 and stress pressure sensor 2.Also comprise notebook computer 4, said notebook computer 4 connects data processing unit 5.The steering order of pressing machine can be sent by notebook computer; After data processing unit obtained instruction, through output processing signals control electromagnetic valve, data processing unit received the information that various sensors send in real time simultaneously; And can it carry out Treatment Analysis; Be split into the real-time testing curve, on screen, show, and the result inputed to carry out data storage in the notebook computer.
Though for illustrative purposes preferred embodiment is described in detail, under the situation that does not break away from the scope of the invention and spirit, can be made multiple change.Therefore, the invention is not restricted to this, but claim institute restricted portion.
