Abstract
The invention relates to a furnace temperature uniformity testing tool and testing support. The furnace temperature uniformity testing tool comprises a testing rod which extends into a hearth in the axial direction of the hearth and a temperature measurement fixing body which is arranged at the front end of the testing rod and used for fixedly installing thermoelectric couples; and at least two thermoelectric couples which are located on one plane in the radial direction of the hearth are arranged on the temperature measurement fixing body in the radial direction of the hearth at intervals, and thermoelectric couple fixing structures for fixing the corresponding thermoelectric couples are further arranged on the temperature measurement fixing body. At the time, a driving device does not need to be started for a mesh belt of a mesh belt furnace, the testing rod goes deep into different positions of the hearth through manual work, the problem that in the prior art, a temperature measurement framework deflects due to mesh belt vibration caused by the fact that the temperature measurement framework moves along with the mesh belt is solved, and the problem that detection loses efficiency due to the fact that the thermoelectric couples originally located in the same plane are not located in the same plane any more due to deflection of the temperature measurement framework is solved; and by means of the testing tool, the working efficiency is improved, and use is convenient.
Description
Technical field
The present invention relates to the test bracket that a kind of test fixture for testing meshbeltfurnace temperature uniformity and this test fixture use.
Background technology
At present, along with the develop rapidly of aerospaceplane, and with the integrating with of international technology, the quality requirement of Aero-Space industry to product is more and more stricter, and the equipment producing these products just becomes the most important link controlling product quality, require that these equipment can put into production use after must carrying out test passes.The final performance of temperature uniformity on the product put into wherein of such as meshbeltfurnace inside has extremely important impact, the furnace temperature of meshbeltfurnace inside is at axial direction and all there is thermograde in the radial direction, so the thermograde of inspection meshbeltfurnace is most important, in prior art to the uniformity test of meshbeltfurnace internal temperature primarily of following two kinds of modes, one is offer thermometer hole at the diverse location place of the furnace wall of meshbeltfurnace, be inserted with thermocouple in thermometer hole and carry out thermometric, but in order to ensure that the muffle tube of meshbeltfurnace inside is not destroyed, so thermometric Kongzui offers the outer wall of muffle tube deeply, therefore this type of temp measuring method can not test the temperature environment of the temperature of muffle tube inside and the reality residing for product, two is place a thermometric framework in meshbeltfurnace inside, heat with meshbeltfurnace, thermometric framework is provided with multiple thermocouple temperature measurement point, but need to open the drive unit that the guipure of meshbeltfurnace can be driven to move, thermometric framework slowly travels forward along with the motion of guipure, gather with this temperature to each position of the muffle tube inside of meshbeltfurnace, because the burner hearth of meshbeltfurnace is usually all long, this type of detection method efficiency is lower, and thermometric framework is with in the guipure running of meshbeltfurnace, vibration due to guipure can cause the deflection of thermometric framework, and truly cannot detect the thermograde in the radial direction of meshbeltfurnace, cause detecting and lost efficacy.
Summary of the invention

Described reference test bar is Collapsible structure, comprises urceolus, is sheathed on the inner core that also can seesaw relative to urceolus of outer barrel and the fixed structure for fixing inner and outer sleeves relative position.
The barrel outer surface of described urceolus is provided with scale.
Described thermometric fixed body is the tripod in isosceles triangle, and the summit of tripod is fixed on the front end of reference test bar, and the base vertical of tripod is in the axis of reference test bar, and the base length of side of tripod equals the diameter of burner hearth.
Beneficial effect of the present invention is: test fixture is extend into the different depth position place of burner hearth inside by this test fixture along burner hearth axial direction by reference test bar, by the thermocouple being installed on thermocouple fixing structure inside, thermometric is carried out to burner hearth inside each position, thermocouple on this test fixture is at least two and is positioned on burner hearth same plane in the radial direction, not only can detect the thermograde in the radial direction of burner hearth position, burner hearth can also be detected along the thermograde on its axial direction in burner hearth position axially by mobile test device, now the guipure of meshbeltfurnace does not need to open drive unit, adopt artificial diverse location place reference test bar being deep into burner hearth, to not only solve in prior art thermometric framework to move the problem being caused thermometric framework deflection by the vibration of guipure brought with guipure, cause detecting inefficacy because the deflection of thermometric framework causes the thermocouple be in same plane to be originally no longer positioned at same plane in prior art, and this test fixture improves operating efficiency and easy to use.
Further, reference test bar adopts telescopic structure, this test fixture can be applied to the temperature uniformity test of the meshbeltfurnace of different length size.
Further, urceolus is provided with scale, the uniformity test of furnace temperature is carried out at the interval that can fix a point uniformly to the position of burner hearth inside.
