Description
Technical field
The present invention relates to material properties test fields, and in particular to a kind of tubulose sample fixture.
Background technique
Tensile property is the fundamental mechanics performance of material.Material plasticity and intensity etc. can be obtained by tensile property test
Performance characterization parameter.Rodlike tensile sample, sheet, arc and pipeline section shape tensile sample are generally divided into according to specimen types.Currently,
Relatively more for rodlike and sheet tensile sample special mould clamp, the connection type of use mostly uses suspension connection, is threadedly coupled
Or clamping etc..
It is fewer for the fixture of tubular pull sample, currently, the fixture that tubular pull sample uses generally uses air pressure
(hydraulic) or V-type bayonet are clamped, these modes generally have the disadvantages that：
1, than cumbersome, and be inconvenient to be loaded；
2, it is chiefly used in room temperature, is not suitable for carrying out high temperature tension test；
3, the tensile sample of radioactivity tubulose sample can not be carried out.
To solve the above-mentioned problems, it realizes convenient, the simple tension test for carrying out tubulose sample, has developed one kind and be used for
Carry out tubulose sample tensile test fixture.
Summary of the invention
In view of the deficiencies in the prior art, the object of the present invention is to provide a kind of tubulose sample fixture, can facilitate
It carries out being loaded of tubular pull sample, connect and its tension test.
Technical scheme is as follows：
A kind of tubulose sample fixture, including suspension pedestal, housing and hoop component；The suspension pedestal and the housing phase
Mutually cooperate so that the hoop component locks tubulose sample.
Further, above-mentioned tubulose sample fixture, the hoop component include being provided with intrados/outer inclined-plane wild card
Bind round and be provided with extrados/outer inclined-plane inside collar；The suspension pedestal and the housing cooperate so that the intrados/
Outer inclined-plane pushes down the extrados/outer inclined-plane so that the inner wall of the inside collar clamps the tubulose sample.
Further, above-mentioned tubulose sample fixture, the inside collar are opened on the axial direction along the tubulose sample
There is deformation gap.
Further, above-mentioned tubulose sample fixture, the suspension pedestal and the housing be connected through a screw thread cooperation with
The inside collar and outside collar is set to cooperate.
Further, above-mentioned tubulose sample fixture further includes for being inserted into the tubulose sample to prevent the tubulose
The end plug of sample deformation.
Further, above-mentioned tubulose sample fixture, one end that the end plug is inserted into the tubulose sample is nose circle.
Further, above-mentioned tubulose sample fixture, the end plug are connect with the suspension pedestal.
Beneficial effects of the present invention are as follows：
(1) present invention is screwed by that will hang pedestal with housing, passes through the axially opposing position between inside collar and outside collar
Shifting makes the internal diameter of inside collar become smaller, and increases with the interface pressure of tubulose sample, to play connection function；
(2) the configuration of the present invention is simple, it is easy to assembly, using quick.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of tubulose sample fixture of the invention.
In above-mentioned attached drawing, 1, suspension pedestal；2, housing；3, inside collar；4, outside collar；5, tubulose sample；6, end plug.
Specific embodiment
The present invention is described in detail below with reference to the accompanying drawings and embodiments.
As shown in Figure 1, the present invention provides a kind of tubulose sample fixture, including suspension pedestal 1, housing 2 and hoop component；
The suspension pedestal 1 and the housing 2 cooperate so that the hoop component locks tubulose sample 5.
Specifically, hoop component includes being provided with intrados/outer inclined-plane outside collar 4 and being provided with extrados/outer tiltedly
The inside collar 3 in face；The suspension pedestal 1 and the housing 2 cooperate so that the intrados/outer inclined-plane pushes down the outer arc
Face/outer inclined-plane is so that the inner wall of the inside collar 3 clamps the tubulose sample 5.
The inside collar 3 is provided with deformation gap on the axial direction along the tubulose sample 5.When suspension pedestal 1 and outside
When 2 cooperation of set squeezes the inside collar 3 and outside collar 4, outside collar 4 passes through intrados/outer inclined-plane and extrados/outer inclined-plane
Between cooperation squeeze inside collar 3 so that deformation occurs to which its inner wall will be made to clamp the tubulose sample 5, deformation for inside collar 3
The presence in gap is more easily deformed the inside collar 3, to clamp the tubulose sample 5.
The connection type for hanging pedestal 1 and the housing 2 can use the ordinary skill in the art, in the present embodiment,
Suspension pedestal 1 and housing 2, which are connected through a screw thread, to be cooperated so that the inside collar 3 and outside collar 4 cooperate.
It further include the end plug 6 for being inserted into the tubulose sample 5 to prevent 5 deformation of tubulose sample in the present embodiment.
One end that the end plug 6 is inserted into the tubulose sample 5 is nose circle, is facilitated insertion into.Optionally, the end plug 6 may be configured as and institute
It states suspension pedestal 1 to connect, easily to extract end plug 6 from tubulose sample 5 out in disassembly.
Current tension test be first according to testing standard by material in need of test be processed into rodlike, sheet,
Then arc or pipeline section shape tensile sample select matched test fixture to carry out tension test according to specimen types.These types
Sample all have different linkage sections, for connect with stretching clamp, including threaded connection section, suspension linkage section or in parallel
Accommodate section etc..In view of the particularity of tubulose sample 5, tests difficult point and be mainly reflected in the connection with stretcher, therefore, this
It invents in the fixture provided, suspension pedestal 1 with cupping machine for being attached；Outside collar 4 is placed in housing 2, with and its
Connected inside collar 3 is combined into fastener, and suspension pedestal 1 is used with housing 2 and is threadedly coupled；Four components are assembled into tubulose examination
Scale tool, it is assembled with tubulose sample 5, the tubular pull sample after forming an assembling.Bottom will be hung after assembling
Seat 1 is screwed with housing 2, so that the internal diameter of inside collar 3 is become smaller by the axially opposing displacement between inside collar 3 and outside collar 4, with pipe
The interface pressure of shape sample 5 increases, to play connection function.
The assembling of this stretching clamp, use process is as follows：5 both ends of tubulose sample are respectively charged into end plug 6 first；By wild card
Hoop 4 is put into housing 2；Inside collar 3 is put into housing 2 and is adjacent to outside collar 4；Suspension pedestal 1 is connected with housing 2,
It manually tightens；Tubulose sample 5 after assembling is attached and is tightened with tubulose sample fixture, each pipe in sample both ends
Shape sample fixture.It is connect after completing sample assembling with tension test fixture, tension test can be started.
Obviously, various changes and modifications can be made to the invention without departing from essence of the invention by those skilled in the art
Mind and range.If in this way, belonging to the model of the claims in the present invention and its equivalent technology to these modifications and changes of the present invention
Within enclosing, then the present invention is also intended to include these modifications and variations.
