Abstract
The utility model discloses a micro-scale low-temperature environmental cabinet used in axial fatigue tests. The micro-scale low-temperature environmental cabinet comprises a cabinet body, through-holes I for test pieces to pass are symmetrically arranged on the upper surface and the lower surface of the cabinet body, and a nitrogen inlet and a nitrogen spillover port are further arranged on the cabinet body. When the micro-scale low-temperature environmental cabinet provided by the utility model, designed aiming to special or universal material testing machines, is used, the to-be-detected part of a test piece is placed in the cabinet body, liquid nitrogen is charged into the cabinet body to maintain the low-temperature state of interior of the cabinet body (such as minus 40 DEG C), for obtaining the temperature environment required by tests. The micro-scale low-temperature environmental cabinet has a simple structure and a small volume, and overcomes the complexity increase in structural design, component size and material techinics, as well as high price and other defects in the conventional large-scale environment caused by the fact that a test fixture is also arranged in the environmental cabinet, and the technical indexes of the environmental cabinet completely conform to the regulations and requirements of related technical standards.
Description
Technical field
The utility model relates to a kind of material test device, and the micro low-temperature environmental cabinet is used in particularly a kind of axial fatigue test.
Background technology
In order to fully understand the material comprehensive mechanical property, need under the different temperature environment, carry out Measurement of Material Mechanical Performance.In the prior art; Because the Material Testing Machine thermocycling environmental device of manufacturer's supply and configuration; The large-scale environmental cabinet of general employing; Test fixture also places within the environmental cabinet during work, therefore makes the complexity of testing equipment aspect structural design, element size and material technology increase, and equipment price is expensive.Initially purchase under the condition that does not have the thermocycling environmental device the user, the usable range of testing equipment receives respective limits.
Summary of the invention
In view of this; The purpose of the utility model provides a kind of axial fatigue test and uses the micro low-temperature environmental cabinet; To enlarge the usable range of existing testing equipment; The simplified structure design perhaps adopts the common material testing machine to cooperate the axial fatigue test of the utility model to make an experiment with the micro low-temperature environmental cabinet, and its technical indicator also can meet correlation technique standard code and requirement.
The purpose of the utility model realizes through following technical scheme: the micro low-temperature environmental cabinet is used in a kind of axial fatigue test; Comprise casing; The top and bottom of said casing are symmetrical set the through hole I that supplies test specimen to pass, and nitrogen air intake opening and nitrogen spillway also are set on the casing.
Further, comprise also being arranged on the outer temperature detection instrument of casing that the probe of temperature detection instrument stretches in the casing through the through hole II that is arranged on the casing;
Further, four bottom of said casing are provided with adjustable for height support.
The beneficial effect of the utility model: the micro low-temperature environmental cabinet is used in the axial fatigue test to special-purpose or the utility model that universal testing machine designs; Position to be detected with test specimen during use is placed in the casing; In casing, lead to LIN then; Make the interior temperature maintenance of casing required low-temperature condition (for example :-40 ℃); Can satisfy the required temperature environment of test, this apparatus structure is simple, and volume is less; Also place the testing equipment that causes within the environmental cabinet in defectives such as the increase of the complexity aspect structural design, element size and the material technology, equipment price costlinesses because of test fixture when having overcome existing large-scale environmental work, its technical indicator meets correlation technique standard code and requirement fully.
Description of drawings
Below in conjunction with accompanying drawing and specific embodiment the utility model is further described:
Fig. 1 is the stereographic map of the said axial fatigue test of the utility model with the micro low-temperature environmental cabinet;
Fig. 2 is the user mode figure of the utility model.
Embodiment
Fig. 1 is the stereographic map of the said axial fatigue test of the utility model with the micro low-temperature environmental cabinet; Fig. 2 is the user mode figure of the utility model.As shown in the figure: the micro low-temperature environmental cabinet is used in the axial fatigue test of present embodiment, comprises casing 2, and the top and bottom of said casing are symmetrical set the through hole I 51 that supplies test specimen 5 to pass, and nitrogen air intake opening 3 and nitrogen spillway 6 also are set on the casing.During use, test specimen is installed, is utilized the anchor clamps 1 of testing machine that test specimen is clamped, after installation environment case and the centering,, in casing, can make an experiment behind the logical nitrogen with heat-preservation cotton shutoff environmental cabinet sample socket slit.Little easy being suitable for of the environmental cabinet volume of the utility model; During low-temperature test work; The sample working portion is inner at environmental cabinet, and jig main body is outside at environmental cabinet, can under the condition that does not change original experimentation device structure, anchor clamps and running parameter, carry out the low temperature environment test.This device is stable, and is easy and simple to handle, and actuating medium (liquid nitrogen) consumption is starkly lower than large-scale environmental cabinet, has the beneficial effect of " energy-conservation, consumption reduction, low cost ".
As further improvement, comprise also being arranged on the outer temperature detection instrument of casing that the probe of temperature detection instrument stretches in the casing through the through hole II 4 that is arranged on the casing to the foregoing description.The temperature detection instrument is set finds out the temperature in the casing accurately, make environment temperature be more prone to control, warranty test result's accuracy.
As the further improvement to the foregoing description, four bottom of said casing are provided with adjustable for height support 7.Can rationally regulate the height of casing according to test specimen length, the scope of application is wider, and practicality is stronger.
Explanation is at last; Above embodiment is only unrestricted in order to the technical scheme of explanation the utility model; Although the utility model is specified with reference to preferred embodiment; But those of ordinary skill in the art makes amendment to the technical scheme of the utility model or is equal to replacement, and does not break away from the aim and the scope of the utility model technical scheme, and it all should be encompassed in the middle of the claim scope of the utility model.
