Brief description
Fig. 1 is the overall sectional view according to fatigue test machine clamp of the present utility model；And
Fig. 2 is the cutaway view Amplified image of the connector of fatigue test machine clamp illustrating Fig. 1.
Specific embodiment
Describe the specific embodiment of fatigue machine fixture of the present utility model below in conjunction with accompanying drawing in detail.Ability
Field technique personnel should be appreciated that the embodiments described below is only to exemplary illustration of the present utility model, not for it
Make any restriction.
Fig. 1 shows the overall section view after being connected with sample to be tested according to fatigue machine fixture of the present utility model
Figure.
Fixture 1 is used for being connected with fatigue machine so that sample to be tested 3 is installed to fatigue machine such that it is able to to be measured
Sample 3 carries out fatigue test, and can measure the anti-fatigue performance of sample to be tested 3.
Sample to be tested 3 is in particular screw-thread steel here, but those skilled in the art are it should be clear that it can also be it
It is any to need to carry out the material of fatigue stress test.
As shown in Fig. 2 this Fig. 2 individually shows fixture 1 of the present utility model, fixture in the way to enlarge with profile
1 is cylindrical in shape shape on the whole, and the outside 11 of cylinder is in cylinder, and the tapered shape in inside 12 of cylinder.
Location structure 13 for positioning sample to be tested 3 is provided with an end face of fixture 1, location structure 13 is used for
Sample to be tested 3 is positioned with respect to fixture 1 in the way of centering and is maintained in the cone-shaped internal part 12 of fixture 1.Specifically, fixed
Bit architecture 13 is formed on the end face of conical nose side of fixture 1.
In currently shown embodiment, as shown in Fig. 2 location structure 13 is formed as the conical nose institute from fixture 1
Recessed on the end face of side.
But the present invention is not limited to this, for instance, it is possible to it is contemplated that although it is not shown, but location structure 13 is formed as company
Continuous groove.Can also phase room, location structure 13 can be formed as discontinuous recess.
In addition, the taper of the cone-shaped internal part 12 of fixture 1 is, for example, 1: 5～1: 10.The height that fixture 1 has is usually 40
～80cm.
And, it will be understood by those skilled in the art that as shown in figure 1, sample to be tested 3 passes through fixed layer (also referred to as fixture)
2 are incorporated on fixture 1.
As shown in figure 1, the combined outside of fixed layer 2 is to connector 1, and its inside is combined with the end of sample to be tested 3.
Fixed layer 3 is formed by watery fusion alloy material, for instance, it is preferred that this watery fusion alloy includes 70-80%
Tungsten (W), the molybdenum (Mo) of 3-8%, the aluminum (Al) of 3-8%, the copper (Cu) of 1-5%, the titanium (Ti) of 1-5%, the magnesium of 1-5%
(Mg), the niobium (Nb) of the nickel (Ni) of 1-5% and 1-5%.
The fusing point of this watery fusion alloy is for example changed into 450-650 DEG C, and is in solid-state at normal temperatures.
But this utility model is not limited to this, those skilled in the art are it is conceivable that other of low temperature melting metallic or alloy
Composition and proportioning structure ratio, as long as it easily can melt in heating, can solidify at normal temperatures.
The forming process of this fixed layer 2 described in detail below and effect.
1) packing ring 4 is set on an end of sample to be tested 3, and is substantially equal to the length of fixture 1 away from end
Position at；
2) sample to be tested 3 being provided with packing ring 4 is arranged in fixture 1, and packing ring 4 is placed on the positioning of fixture 1
In structure 13, by sample to be tested 3 with respect to fixture 1 centering；
3) irrigate, in the space between fixture 1 and sample to be tested 3, the watery fusion alloy being in a liquid state；
4) watery fusion alloy graining and form fixed layer 2, thus fixture 1 is combined by this fixed layer 2 with sample to be tested 3；
5) fixed layer 2 is formed in the other end of sample to be tested 3 with same step, thus by fixed layer 2 by fixture 1
Be combined with the other end of sample to be tested 3.
By by above step 1) to 5) conjunction that formed is placed on fatigue machine and carries out fatigue test, thus
The anti-fatigue performance of the clamped sample to be tested 3 of detection.
Using after finishing, described conjunction is heated so that melting in watery fusion alloy deliquescing, thus taking out to be measured
Sample 3.
Preferably for above step 2), location structure 13 is located at the head side of cone-shaped internal part of fixture 1
On end face.
This utility model by location structure, sample to be tested is centrally located within fixture 1, and and then utilizes low temperature
Molten alloy or low temperature melting metallic, by fixture 1 and sample to be tested 3 secure bond, enable to when carrying out fatigue test,
Sample to be tested will not rupture because producing stress concentration in the junction of fixture.After being completed, can be melted by heating low temperature
Merge gold or low temperature melting metallic and fixture 1 and sample to be tested 3 are separated.
The foregoing is only the specific embodiment of utility model, be not intended to this utility model is imposed any restrictions, every
It is carried out wait by change and modify according to this utility model, all within the category of the art of this patent protection scheme.
