Abstract
The utility model belongs to metal material and metallic material product impact specimen lateral expansion determination techniques field, more particularly to a kind of impact specimen lateral expansion test fixture.It includes base body, amesdial is fixed through jaws and by the bolt at the top of base body, cushion block is additionally provided between the bolt and base body, the level height effect with adjustment amesdial, the amesdial measurement end is provided with cylinder measurement head.The utility model is ensureing test fixture from heavy and light by supporting the use base body, cushion block and measurement head, while carrying convenient, also solves in test process because shape difference is big, and causes error bigger difficulty.The utility model can effectively fix the amesdial that measurement is used by using the jaws, and the jaws can clamp the amesdial of plurality of specifications, and assembling and dismounting are simple, strong operability.
Description
Technical field
The utility model belongs to metal material and metallic material product impact specimen lateral expansion determination techniques field, especially
It is related to a kind of impact specimen lateral expansion test fixture.
Background technology
Metal material does not produce substantially deformation and destruction suddenly occurs and is referred to as brittle fracture, and brittle fracture is past because of emergentness
Judged come the fragility to metal material often through impact test in extensive damage, therefore actual production toward causing, and side
It is then an important tests target component of impact test to swell increment.The lateral expansion of sample after detecting impact test
Amount, anticipation is carried out come the fragility to metal material.GB/T 229 is directed to metal sample carries out impact test, and examination is measured after experiment
The lateral expansion of sample, existing lateral expansion test fixture, instrument is heavy, assembling inconvenience, carries or move inconvenience, or even
Easily cause extruding accident, measurement end is sharp body, and after impact test impact specimen lateral expansion heterogeneity, use point
Sharp body is measured can cause measurement error larger.
Utility model content
According to above the deficiencies in the prior art, technical problem to be solved in the utility model is：A kind of impact examination is provided
Sample lateral expansion test fixture, its base body is light, easy to assembly, measurement error is small.
The utility model is realized by following technical scheme：A kind of impact specimen lateral expansion test fixture,
Including base body, amesdial through jaws and being fixed by the bolt at the top of base body, the bolt with
Cushion block is additionally provided between base body, the level height effect with adjustment amesdial, the amesdial measurement end is installed
There is cylinder measurement head, can effectively ensure that test lead remains perpendicular to horizontal plane.
The jaws set in base body, can effectively fix the amesdial that measurement is used.Amesdial can be with high accuracy
Measure the deflection of impact specimen.The cushion block can effectively adjust the levelness of amesdial, it is ensured that the accuracy of test result.
It is located at directly over base body the bolt, the effect with fixed jaws and cushion block.
By supporting the use base body, cushion block and measurement head, ensureing test fixture from heavy and light, carrying easily same
When, also solve because shape difference is big in test process, and cause error bigger difficulty.
Preferably, the height of described base body is 59 millimeters, and length is 150 millimeters, and base body deadweight is small, is carried
It is convenient with carrying.
Preferably, the length of described cushion block is 10 millimeters, and width is 10 millimeters, is highly 15 millimeters.
Preferably, described bolt is M6 bolts.
Preferably, a diameter of 8 millimeters of described measurement head, are highly 9 millimeters.
The beneficial effects of the utility model are：
The utility model, in guarantee test fixture from heavy and light, is taken by supporting the use base body, cushion block and measurement head
With it is convenient while, also solve because shape difference is big in test process, and cause error bigger difficulty.The utility model leads to
Crossing can effectively fix the amesdial that measurement is used using the jaws, and the jaws can clamp thousand points of plurality of specifications
Table, assembling and dismounting are simple, strong operability.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
In figure：1st, base body；2nd, amesdial；3rd, jaws；4th, bolt；5th, cushion block；6th, head is measured.
Specific embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings：
As shown in figure 1, a kind of impact specimen lateral expansion test fixture described in the utility model, including base body
1, amesdial 2 is fixed through jaws 3 and by the bolt 4 installed in the top of base body 1, the bolt 4 and base master
Cushion block 5 is additionally provided between body 1, the level height effect with adjustment amesdial 2, the measurement of the amesdial 2 end is provided with
Cylinder measurement head 6, can effectively ensure that test lead remains perpendicular to horizontal plane.
The jaws 3 set in base body 1, can effectively fix the amesdial 2 that measurement is used.Amesdial 2 can be with height
The deflection of precision measure impact specimen.The cushion block 5 can effectively adjust the levelness of amesdial 2, it is ensured that test result
Accuracy.It is located at directly over base body 1 bolt 4, the effect with fixed jaws 3 and cushion block 5.
By supporting the use base body 1, cushion block 5 and measurement head 6, ensureing test fixture from heavy and light, it is convenient to carry
While, also solve because shape difference is big in test process, and cause error bigger difficulty.
Preferably, the height of described base body 1 is 59 millimeters, and length is 150 millimeters, and base body deadweight is small, removes
It is convenient to transport and carry.
Preferably, the length of described cushion block 5 is 10 millimeters, and width is 10 millimeters, is highly 15 millimeters.
Preferably, described bolt 4 is M6 bolts.
Preferably, a diameter of 8 millimeters of described measurement head 6, are highly 9 millimeters.
Certainly, the above is only preferred embodiment of the present utility model, it is impossible to be considered as new to this practicality for limiting
The scope of embodiments of type.The utility model is also not limited to the example above, and those skilled in the art are in this reality
With the impartial change made in new essential scope with improve etc., patent covering scope of the present utility model all should be belonged to
It is interior.
