The fixture has the advantages of being novel in structure, reliable in test and practical, and a good application effect is achieved in testing work.
Description
Technical field
It is a kind of under hot environment that the utility model provides, the test fixture of test material compression performance index.
Background technology
Compressive property test is one of important evidence of evaluation quality of materials, and domestic material mechanical performance measuring technology lacks the method for testing of compressive property index for a long time.And in high temperature tension test, for guaranteeing that sample is all the time along the stressed requirement of axial direction, the articulated structure that the matable assemblies such as the pull bar of stretching clamp adopt pin to connect, to realize automatic centering, and most bodies of heater are the slim-lined construction that diameter only has 30mm, space is comparatively narrow and small, causes carrying out high temperature compressed test with stretching clamp.
Utility model content
The purpose of this utility model be for the existing deficiency of prior art and application demand provide a kind of for test material compression performance index at high temperature technical scheme, this scheme is meeting on the basis of compressibility of materials energy testing standard regulation principle, in the small space of drawing by high temperature stove, utilize relative motion principle to realize the method that the tensile property test of material is converted into compression performance test.Obtained in test good effect, fixture has novel structure, tests reliable, convenient and practical feature, has solved the problem that prior art cannot be carried out material at high temperature compression performance index test.
The technical scheme that the utility model adopts: a kind of high temperature compressed fixture, comprises upper connecting rod, lower link, upper holder block and lower lock block;
Described upper connecting rod is cylindrical, and the stretching end of upper connecting rod is provided with stretching cavity along draw direction, and is provided with through hole on limit, elongated cavity side;
Described lower link is cylindrical, and the stretching end of lower link is provided with stretching cavity along draw direction, and is provided with through hole on limit, elongated cavity side;
The external diameter of described lower link is less than the internal diameter of the cavity that stretches in upper connecting rod, and the stretching end of drop-down boom inserts in the stretching cavity of upper stretching bar;
Described upper holder block and lower lock block are respectively through the through hole on upper connecting rod and lower link.
In technique scheme, the through hole on described upper connecting rod and lower link is rectangular opening.
In technique scheme, the center of described upper holder block and lower lock block adjacent surface is respectively arranged with locating slot.
In this programme, the principle adopting is exactly by pulling upper and lower pull bar that upper and lower pull bar is moved to both sides from two ends, in motion, drive upper and lower briquetting to press together, and compressed object is just arranged between upper and lower briquetting, therefore the power stretching is just converted to pressure by this device, and in order to meet the test condition of high temperature, the mode that can heat by localized hyperthermia at tested position meets, and therefore just the unappeasable condition of conventional test mode can be realized by this programme.
The utility model has the advantage of that this compression clamp is simple in structure, be easy to processing, can also meet at high temperature tested object is carried out to compression verification easily, by simple stretching mode, realized pressure test simultaneously.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 be in another embodiment upper connecting rod partly cut open figure;
Fig. 3 is the complete section figure of lower link in another embodiment;
Wherein: the 1st, upper connecting rod, the 2nd, lower link, the 3rd, stretching cavity, the 4th, stretching cavity, the 5th, upper holder block, the 6th, lower lock block, the 7th, tested sample, the 8th, through hole, the 9th, through hole.
Embodiment
Now by reference to the accompanying drawings the utility model is further illustrated.
As shown in Figure 1, upper stretching bar 1 is cylindrical, one end is bare terminal end, on this end, be provided with screw thread for being connected and fixed with cupping machine, the other end of upper stretching bar 1 is the end that stretches, the end that stretches is provided with a stretching cavity 3 on draw direction, in the side of this stretching cavity 3, is provided with two through holes 8 along Central Symmetry place, can place upper holder block 5 and lower lock block 6 in through hole 8; The setting the same as upper stretching bar 1 of drop-down boom 2, one end is bare terminal end, is provided with the screw thread for connecting on this end, and the other end is the end that stretches, stretch end along being provided with stretching cavity 4 on draw direction, and the side of this same stretching cavity 4 is provided with two through holes 9 along Central Symmetry place; But the race diameter of drop-down boom 2 is slightly less than the inner ring diameter of the cavity 3 that stretches in stretching bar 1.
The stretching end of drop-down boom 2 is inserted in the stretching cavity 3 in upper stretching bar 1, rotate drop-down boom 2, the through hole 9 on drop-down boom 2 is overlapped with through hole 8 positions in upper stretching bar 1.Then upper holder block 5 and lower lock block 6 are inserted through to through hole 8 and through hole 9; For fixing tested sample 7, at upper holder block 5 and the obverse center of lower lock block 6, a locating slot is set respectively, tested sample 7 is placed in locating slot.
