Description
Technical field
This utility model is related to a kind of cuboid sample lateral displacement measurement apparatus, is particularly well-suited to the cuboid strength of materials
Test, belongs to apparatus class.
Background technology
Because the property of various types of materials is different, the strength problem of many class materials is people's Important Problems of interest, visits
Study carefully its load performance, scalability can make its performance using maximizing in engineering, ensure safety simultaneously, thus reaching optimal
High performance-price ratio utilization rate.Metal, organic material, composite, natural material equal strength size, ductility difference are bright
Aobvious, the two needs to coordinate reference, just more meaningful.
Chinese scholars expand many research work in terms of materials mechanics experimental, focus mostly in all kinds of intensity of material
Test.China Patent Publication No. CN101180529, publication date 2008-5-14, invention entitled in compression test, especially
It is the collar measuring sample lateral deformation when single shaft or triaxial compression test, be a kind of examination that can measure sample lateral deformation
Experiment device.But it is served only for cylindrical sample, the different specimen shape of different test requirements documents.When sample must have one side to be seen
During survey, that is, in the destructive process in material each stage, follow the tracks of and observation microcrack initiation, extension and insertion process, including sample
Surface and internal rupture two parts, the measurement of cuboid sample lateral displacement is most important, and for subsequent analysis, it destroys machine for this
Reason etc. is respectively provided with important meaning.And existing method is directed to cuboid sample measurement strain common method for patch strain gauge method etc.,
But in above-mentioned special test, the method operating process of patch foil gauge is complicated, with axially loaded data cannot synchronous recording,
Accurate synchrodata can be obtained using ring extensometer, but matched fixture is chain, and only
It is applied to cylindric sample, equally cannot solve lateral displacement measurement in above-mentioned special test for the cuboid sample, impact examination
The integrity tested.
Content of the invention
For above-mentioned existing problems, the purpose of this utility model is to provide a kind of cuboid sample lateral displacement measurement dress
Put, this device is connected with traditional ring extensometer using simple accessory, can achieve noiseless to sample inspection surface, and can
Synchronous recording sample lateral displacement.
To achieve these goals, this utility model adopts the following technical scheme that：
A kind of cuboid sample lateral displacement measurement apparatus, the folder be connected including ring extensometer and with ring extensometer
Tool, described fixture is L-shape, and fixture is a pair, and fixture one end is bare terminal end, and the fixture other end is connection end, and connection end has
Axis hole, connecting shaft is fixedly installed in axis hole, and connecting shaft is connected with two long-armed touches of ring extensometer respectively.
Due to employing above technical scheme, this utility model is changed to existing ring extensometer institute matched clamp
Enter.Employ L-type fixture, the deformation in cuboid material a direction can be measured, obtain under each loading environment
Destructive process whole process data, and do not affect observation and the test in other faces of cuboid material sample, there is important theory and reality
Border meaning.
This utility model has the advantages that：
(1) the method is more than the L-type fixture of measured and monitored the growth of standing timber material and connecting shaft by rigidity it is ensured that in process of the test, device
Part does not deform, and affects result of the test.
(2) the method institute use principle is simple, and fixture is fixed on two opposite faces of sample, independent of the test in other faces
With observation, do not affect sample internal rupture and destroy overall process observation and record.
(3) the used device of the method can be connected with numerous testing machines, strong applicability.
(4) the method institute can easily be unloaded after the completion of test using device, is easily installed.
(5) this utility model is reasonable in design it is easy to processing is it is easy to operate and time-consuming, can repeat to transport simultaneously
With economizing on resources.
Brief description
Fig. 1 is structural representation of the present utility model.
Specific embodiment
Below in conjunction with the accompanying drawings this utility model is described in detail, sees accompanying drawing 1.
A kind of cuboid sample lateral displacement measurement apparatus, it is made up of ring extensometer and fixture, and described fixture is in L
Shape, fixture is a pair, and fixture one end is bare terminal end 2, and fixture bare terminal end 2 length is more than the half of institute's test specimens thickness but is not more than
Sample thickness is preferred, and the fixture other end is connection end 3, and the length of fixture connection end 3 is less than the half of specimen width, connection end 3
On have axis hole, connecting shaft 5 is fixedly installed in axis hole, and long-armed 1 touch is even with two of ring extensometer respectively for connecting shaft 5
Connect.
During work, fixture bare terminal end 2 passes through adhesives in sample middle side edge, and protection pad 4 is fixed on ring
On extensometer, connecting shaft 5 is limited in hook on ring extensometer long-armed 1 protection pad 4, after fixture is fixing, two connections
Between end, initial distance gearing is long-armed makes spring be in extended state, and when sample occurs lateral expansion, bare terminal end 2 does not become
Shape, is only moved to sample expansion direction with sample, and the end 3 that is connected, to equidirectional movement, is drawn further by connecting shaft 5
Stretch the spring on ring extensometer, thus obtaining sample lateral displacement data.When sample lateral displacement is excessive, ring will be exceeded
During extensometer maximum range, protection pad 4 automatically springs open, and two long-armed 1, to original state closure, protect ring extensometer.
L-type fixture is applied to the test of various types of materials square coupons, is particularly suited for the test of sample lateral expansion, ring
Extensometer can be connected with the testing machine of coupling, thus reaching test objective.
Claims (1)
1. a kind of cuboid sample lateral displacement measurement apparatus, the fixture be connected including ring extensometer and with ring extensometer,
It is characterized in that：Described fixture is L-shape, and fixture is a pair, and fixture one end is bare terminal end (2), and the fixture other end is connection end
(3), connection end (3) have axis hole, connecting shaft (5) is fixedly installed in axis hole, connecting shaft (5) respectively with ring extensometer
