Description
Technical Field
The utility model relates to a thermal expansion appearance technical field, concretely relates to universal fixturing of high temperature thermal expansion appearance.
Background
The push rod method thermal expansion instrument is used for testing the thermal expansion coefficient of a solid sample, the thermal expansion instrument is applied to various materials, the instrument tests the change of the length of the material along with the change of temperature, however, not all the materials can be tested to obtain the accurate thermal expansion coefficient, the reason is mainly two aspects, on one hand, the thermal expansion test has higher requirements on the sample, taking a German relaxed DIL402 thermal expansion instrument as an example, the thermal expansion instrument only tests a cylinder with the fixed size of 25 mm and the diameter of 4-8 mm.
Because the conventional metal material can reach the size by wire cutting, the sample can be limited to the metal material test, and for the metal sample with few or thin samples and most of non-metal samples, the high polymer material is difficult to process to the standard sample size for testing; on the other hand, in the temperature rise process, the sample may be softened, decomposed, melted, etc. to cause the sample shape to change, which results in the thermal expansion coefficient being unable to test, and the most serious is that the melted sample will stick to the alumina or quartz clamp and alumina sleeve of the thermal expansion instrument, the alumina push rod, which causes the damage of the instrument clamp, and generates high maintenance cost and replacement cost of the support.
SUMMERY OF THE UTILITY MODEL
The utility model aims at overcoming that prior art exists because conventional metal material can reach this size through the wire-electrode cutting, the sample can only be restricted to the metal material test, and less or thinner metal sample and most of non-metallic sample to the sample, macromolecular material all hardly processes the problem that the standard sample size was tested, the universal fixturing of a high temperature thermal expansion appearance is provided, this universal fixturing of high temperature thermal expansion appearance has the wide range size sample test that can realize length from 1 millimeter to 25 millimeters, can effectively take precautions against the sample simultaneously because decompose and melt the pollution support that brings, the effect of experimental cost has been reduced.
In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a universal fixturing of high temperature thermal expansion appearance, includes thermal expansion appearance, sleeve pipe, base and gasket, the inside one side of thermal expansion appearance is provided with the recess, and the inside ejector pin that is provided with of recess, the ejector pin outside is provided with the sleeve pipe, the sleeve pipe bottom is provided with the base, the ejector pin other end is provided with the gasket.
Preferably, the sleeve, the base and the gasket are made of alumina materials.
Preferably, the gasket has a diameter of 5 mm and a height of 3 mm.
Preferably, the gasket is of cylindrical configuration.
Compared with the prior art, the utility model provides a universal fixturing of high temperature thermal expansion appearance possesses following beneficial effect:
the utility model discloses can realize that length from 1 millimeter to 25 millimeters's wide range size sample test, can effectively take precautions against the sample simultaneously because decompose and melt the pollution support that brings, reduce the experiment cost, need not consume the import support, only just can carry out the thermal energy experiment to most of samples with domestic sleeve pipe and gasket, the utility model has the advantages of being scientific and reasonable in structure, convenience safe in utilization provides very big help for people.
