Description
Technical field
The present invention relates to clamping device, and in particular to suitable for the clamp system of tension failure sample parameter measurement.
Background technology
One of oil, the main object of geological prospecting, it is a kind of sticky, dark brown liquid, is referred to as " industrial blood
Liquid ".There is petroleum storage upper crustal some areas.Main component is the mixture of various alkane, cycloalkane, aromatic hydrocarbon.Oil
Mainly it is made up of different hydrocarbon mixing, the chemical element of composition oil is mainly carbon (83%~87%), hydrogen
(11%~14%), remaining is sulphur (0.06%~0.8%), nitrogen (0.02%~1.7%), oxygen (0.08%~1.82%) and micro-
Measure metallic element (Ni-V-Fe, antimony etc.).The chief component that the hydro carbons formed constitutes oil is closed by carbon and hydrogenation, accounted for
95%~99%, various hydro carbons are divided into by its structure：Alkane, cycloalkane, aromatic hydrocarbon.General natural oil not olefin-containing and it is secondary
Process the alkene and alkynes often not waited containing quantity in product.Sulfur-bearing, oxygen, nitrogen compound are harmful to oil product, in oil
The removing oil that should be tried one's best in processing is mainly used as fuel oil and gasoline, is also many chemical industries, such as solution, change
The raw material of fertilizer, insecticide and plastics etc..
In oil equipment job shop, often some samples are carried out with tension failure experiment, tension failure experiment refers to
The test method of material property is determined in the case where bearing axial tensile loads, the data obtained using tension test can determine material
Elastic limit, elongation, modulus of elasticity, proportional limit, area reduction amount, tensile strength, yield point, yield strength and other
Tensile property index, the tension test carried out under high temperature can obtain creep data, and what tension test can determine material one is
Row intensity index and plasticity index.Intensity typically refer to material resist under external force generation elastic deformation, plastic deformation and
The ability of fracture.Material when bearing tensile load, when load do not increase and continue to occur the phenomenon that is substantially plastically deformed
Surrender.Stress during surrender is produced, claims yield point or physics yield strength.There are many materials in engineering without significantly in the wrong
Take a little, the stress value when afterflow that generally material is produced is 0.2% claims proof stress as yield strength
Or offset yield strength.The maximum stress value that material is reached before fracturing, claims tensile strength or strength degree.Tension test exists
Carried out in Material Testing Machine.Testing machine have mechanically, the pattern such as fluid pressure type, electro-hydraulic or electron servo formula.Sample type can be
Material total cross-section, the standard specimen of circular or rectangle can also be processed into.Some samples such as reinforcing bar, wire rod are typically not required to
Process and keep its total cross-section to be tested.Sample should avoid material structure from being cooled when preparing, hot worked influence, and ensure
Certain finish.
With continuing to develop for technology, the measurement of the strength of materials is slowly realized to be calculated by computer software measurement, but
Tensile sample is had no progeny the measurement of parameter, such as elongation after fracture, the contraction percentage of area, is also mainly passed through manual measurement and is calculated and completes.
Carry out tensile sample have no progeny parameter measurement when, it is necessary first to tester is according to plane of disruption pattern already off tensile sample
It is stitched together, then to having no progeny gauge length and cross section diameter is measured, but spliced tensile sample is when measuring, because not
Sufficiently stable fixation can be obtained, when often resulting in manual measurement, larger measurement error occurs, has a strong impact on stretch test result
Accuracy.
The content of the invention
The technical problems to be solved by the invention be manual measurement tensile sample have no progeny parameter when, the fixed dress of sample
Put, the problem of measurement error is larger, it is therefore intended that provide in the clamp system suitable for tension failure sample parameter measurement, solution
State problem.
The present invention is achieved through the following technical solutions：
Suitable for the clamp system of tension failure sample parameter measurement, including base, guide groove is provided with base, is oriented to
One end of groove is provided with fixed support block, and the one end of guide groove away from fixed support block is provided with sliding support block, sliding support
It is provided with move portion, move portion below block and is provided through screw rod, move portion is screwed with screw rod, move portion and screw rod is positioned at leading
Into groove, when screw rod is rotated, move portion can be moved along screw rod in guide groove, that is, slidably support side of the block to fixed support block
To movement；The distance between fixed support block and sliding support block are adjusted according to sample size, screw rod is rotated, when move portion is to admittedly
When the direction for determining support block is moved to suitable position, sample is placed between fixed support block and sliding support block, will be tried
Sample is stitched together, and sample can keep the state of splicing, so that the measurement relatively stablized, phase under self gravitation effect
For direct labor's measurement, measurement error is reduced.
Further, the fixed support block and sliding support block are set by axisymmetrical of their center line, and it is tied
Structure is identical.
Further, the fixed support block and sliding support block upper surface ecto-entad be disposed with baffle plate,
Flat support portion and circle arc support portion, flat support portion surface are plane, and for measuring tabular part, tabular part is put
In flat support portion, clamped using the effect of baffle plate, be easy to measurement, circle arc support portion surface is arc surface, for surveying
Measure cylindric part or arc part.
Further, also extended through in the move portion and be provided with guide rod, the screw rod is parallel to each other with guide rod, it is mobile
When portion is moved in guide groove, guide rod plays guide effect, the movement of move portion and sliding support block is more stablized, it is to avoid
Fixed support block and the change in location of sliding support block are larger, cause final measurement error too big.
Further, the screw rod is connected with drive device, and drive device drives screw rod to rotate, and electricity may be selected in drive device
Machine.
Further, controller is connected with the drive device, controller is PLC common on the market, is used
To control the rotation direction and rotating speed of drive device.
The present invention compared with prior art, has the following advantages and advantages：
The present invention is applied to the clamp system of tension failure sample parameter measurement, and sample is placed on it and can relatively be stablized
Ground is measured, and reduces measurement error；And moved by the rotation of screw rod, move portion and sliding support block to fixed support block,
The distance between fixed support block and sliding support block can be adjusted, the clamp system is applied to the examination of different sizes
Sample；The upper surface ecto-entad of fixed support block and sliding support block is disposed with baffle plate, flat support portion and circular arc branch
Support part, makes the clamp system be applied to part of different shapes.
