Abstract
The utility model belongs to the technical field of non-metal surface temperature measurement. In a thermocouple, a positive pole and a negative pole of a temperature measuring thermocouple leading-out wire (8) are welded on a thermocouple temperature-measuring operation surface (1). The thermocouple temperature-measuring operation surface (1) is a silver/copper sheet. Heat insulation silicone rubber (2) is filled between the thermocouple temperature-measuring operation surface (1) and a fixed copper head (3) for binding the two members together. One end of a sliding rod (4) is welded with the fixed copper head (3), and the other end is inserted into a sliding cylinder (6) and is positioned with a compression spring (5) and the inner wall of a sliding cylinder (6). One end of a fixed mounting rod and mounting bracket (7) is welded with the sliding cylinder (6). The external surface is used as a mounting/clamping operation surface. Contact surface force between the thermocouple temperature-measuring operation surface (1) and a measured object can be adjusted through changing the mounting position. The non-adhibition type surface temperature-measuring thermocouple settles the following problems: non-metal material abrasion caused by long-period high/low temperature fatigue test adhesive, low temperature measuring accuracy, incapability of changing an adhibited thermocouple after damage, and canopy glass damage caused by changing of the adhibited thermocouple.

Prior art: general surface temperature measurement metal adopts thermopair directly to weld or pastes, and nonmetal employing is directly pasted.
The problem and the defective that concerning nonmetallic surface, adopt direct adhesive type to exist: the one, can cause extra corrosion to nonmetallic materials through long-term high fatigue testing at low temperature alite paste; The 2nd, alite paste has certain thickness to cause thermometric inaccurate; The 3rd, paste and can't change after thermopair damages or the replacing meeting damages canopy glass.
Non-adhesive type surface temperature measurement thermopair (sensor) adopts the thermocouple temperature measurement face directly to be pressed in testpieces thermometric surface, and snap-in force is adjustable simultaneously.The successful solution first of non-adhesive type surface thermocouple above-mentioned direct the adhesive type problem and the defective that exist, successfully apply in the gentle and quiet power of polytypic canopy height, the torture test, change very convenient, canopy glass there is not injury, satisfied canopy and decided the needs in longevity, and can be popularized and applied in other surface temperature test.。
Summary of the invention
The objective of the invention is:
The invention solves the inaccurate problem of etching problem, thermometric that long-term high fatigue testing at low temperature alite paste causes nonmetallic materials and paste and to change after thermopair damages or problem that the replacing meeting damages canopy glass.
Technical scheme of the present invention is:
Non-adhesive type surface temperature measurement thermopair comprises thermocouple temperature measurement workplace 1, heat insulation silicon rubber 2, and fixedly copperhead 3, sliding bar 4, holddown spring 5, slide cartridge 6, fixed installation bar and mounting bracket 7 and temperature thermocouple extension line 8; The positive and negative polarities point of temperature thermocouple extension line 8 is welded on the thermocouple temperature measurement workplace 1, thermocouple temperature measurement workplace 1 is the silver-bearing copper sheet, thermocouple temperature measurement workplace 1 and fixing 3 stuffed heat insulated silicon rubber 2 of copperhead and the two is bonded together, sliding bar 4 one ends and fixedly copperhead 3 welding, one end inserts in the slide cartridge 6 and with holddown spring 5 and slide cartridge 6 inwalls and locatees, fixed installation bar and mounting bracket 7 one ends and slide cartridge 6 welding, its outside surface is as installing the clamping workplace, and the surface of contact power between thermocouple temperature measurement workplace 1 and measurand can be regulated in the change installation site.
Described silver-bearing copper sheet diameter is 0.1-0.3mm for 2-4mm thickness.
The elasticity coefficient of described holddown spring is 7～8g/mm.
Described temperature thermocouple extension line is selected 0.2mmT type silk material for use.
Advantage of the present invention is:
Adopt non-adhesive type surface temperature measurement thermopair (sensor), do not have alite paste that canopy glass is caused corrosion, warranty test spare can not change nonmetallic fatigue lifetime because of other organic solvent corrosion.
The adhesive type thermopair has alite paste, has influenced the heat transmission of testpieces, and non-adhesive type thermocouple temperature measurement face directly is pressed in testpieces thermometric surface, and thermometric is more accurate.
Adhesive type damage back thermopair and alite paste be difficult to refute from clean out, change the original fatigue quality of nonmetallic surface.Adopt non-adhesive type surface temperature measurement thermopair (sensor), the thermocouple temperature measurement face directly is pressed in testpieces thermometric surface, and it is very convenient to damage the back replacing, in testpieces surface noresidue, canopy glass is not had injury.
