Suit insulation magnetic bead, is set with protection pipe on standard couple, is bundled into tested thermocouple and standard couple using thin chromium silk
Circular a branch of, so that the measurement end of tested thermocouple is uniformly distributed one week around the measurement end of standard couple, and be in and vertically mark
On the same section of quasi- thermocouple.Existing fixed form of tying up is merely capable of for tested thermocouple and standard couple being bundled into circle
The couple bundle of shape is it is impossible to the measurement end of the tested thermocouple of guarantee is uniformly distributed around the measurement end of standard couple；In addition, assay furnace
The diameter in chamber is much larger than couple bundle, the existing radial center position tying up fixed form it cannot be guaranteed that couple bundle is in calibrating furnace chamber
Put, its centering is poor, verification result error is big.
Content of the invention
In order to overcome the fixation of existing harness to exist to tie up, uneven, couple bundle centering is poor, verification result error is big
Deficiency, a kind of this utility model structure of offer is simple, fix the thermoelectricity uniform, couple bundle centering is good, verification result error is little
Even calibrating locating support.
This utility model solves its technical problem and be the technical scheme is that a kind of thermocouple calibration locating support, its
Including at least two locating bodies it is characterised in that: described locating bodies are cylindrical, have at the axis of this locating bodies
One central through hole, on the locating bodies of this central through hole periphery, annular is evenly equipped with some installation through-holes.
Some screwed holes, this screwed hole and described installation through-hole are radially had on the circumferential surface of described locating bodies
Corresponding insertion, in described screw thread in the hole, corresponding matching has holding screw respectively.
At least two positioning through hole are had on the sagittal plane of described locating bodies, in described positioning through hole respectively
It is correspondingly provided with locating rod, this locating rod is by described locating bodies axial restraint.
Described installation through-hole is 8-10.
This utility model includes at least two locating bodies, and locating bodies are cylindrical, have at the axis of locating bodies
One central through hole, on the locating bodies of central through hole periphery, annular is evenly equipped with some installation through-holes, and its structure is simple；Standard hot
Galvanic couple is axially fixed in central through hole, and tested thermocouple is fixed on installation through-hole, and it is arranged around standard couple, and it is fixed
Uniformly；Couple bundle is accurately placed in the furnace chamber center of assay furnace by this utility model, it makes, and couple bundle centering is good, verification result by mistake
Difference is little.
Brief description
The utility model is described in further detail with reference to the accompanying drawings and examples.
Fig. 1 is a kind of structural representation of the present utility model.
In figure labelling: 1. locating bodies, 2. central through hole, 3. installation through-hole, 4. screwed hole, 5. holding screw, 6. position
Through hole, 7. locating rod.
Specific embodiment
As shown in figure 1, a kind of thermocouple calibration locating support, it includes at least two locating bodies 1.Locating bodies 1 are in circle
Column, its circumferential surface is fitted with the inner chamber of assay furnace (not shown).Be limited locating bodies 1 transmission heat processed, this practicality
Locating bodies in new can be made up of conventional adiabator, and in the present embodiment, locating bodies 1 are made using fire clay,
Its a diameter of 40mm, a height of 2.5mm.
It should be noted that the quantity of locating bodies 1 should be according to the length sets itself of tested thermocouple.In tested thermoelectricity
Even length shorter it should at least be respectively arranged at two ends with locating bodies 1 at it.
In FIG, have a central through hole 2 at the axis of locating bodies 1, in the positioning basis of this central through hole 2 periphery
On body 1, annular is evenly equipped with some installation through-holes 3.Wherein, a diameter of 9mm of central through hole 2, installation through-hole 3 a diameter of
3.5mm.The center that the two ends being cased with the standard couple (not shown) of protection pipe are separately fixed at two locating bodies 1 leads to
So as to measurement end is stretched out by the central through hole 2 of locating bodies 1 in hole 2；Equally, by the two of tested thermocouple (not shown)
End is separately fixed in the installation through-hole 3 of two locating bodies 1 so as to measurement end is stretched out by the installation through-hole 3 of locating bodies 1.Need
It is noted that the quantity of installation through-hole 3 determines according to the quantity of tested thermocouple, generally 8-10.In the present embodiment,
As shown in figure 1, installing hole is set to 8.
For fixing the axial location of tested thermocouple, if as shown in figure 1, radially having on the circumferential surface of locating bodies 1
Dry screwed hole 4, the insertion corresponding with installation through-hole 3 of this screwed hole 4, in screwed hole 4, corresponding matching has holding screw 5 respectively.Adjust
Whole tested thermocouple, so as to measurement end is on same vertical cross-section with the measurement end of standard couple, screws in holding screw 5,
By tested thermocouple clamping between the inwall of holding screw 5 and installation through-hole 3.
As shown in figure 1, at least two positioning through hole 6 are had on the sagittal plane of locating bodies 1, divide in positioning through hole 6
It is not correspondingly provided with locating rod 7, this locating rod 7 nut through its end is by locating bodies 1 axial restraint.It should be noted that it is fixed
The quantity of position through hole 6 is to be set according to actually used situation, for preventing tested thermocouple from reversing around standard couple, in this reality
Apply in example, the quantity of positioning through hole 6 is set to two, it is symmetricly set on the sagittal plane of each locating bodies 1.
This utility model, when using, the two ends being cased with the standard couple of protection pipe is separately fixed at two locating bodies
So as to measurement end is stretched out by the central through hole 2 of locating bodies 1 in 1 central through hole 2, tested thermocouple two ends are fixed respectively
In the installation through-hole 3 of two locating bodies 1, it is arranged around standard couple, and it is fixing uniformly；The measurement end of tested thermocouple
Stretched out by the installation through-hole 3 of locating bodies 1, adjust tested thermocouple so as to measurement end is in the measurement end of standard couple
On same vertical cross-section, screw in holding screw 5, tested thermocouple axial grip is fixed, meets the requirement of vertification regulation；Positioning
Bar 7 is worn on the positioning through hole 6 being connected on two locating bodies 1, by the axially locating support equipped with the tested thermocouple of standard hot even summation
Stretch into the inner chamber of assay furnace, the circumferential surface of locating bodies 1 is fitted with the inner chamber of assay furnace, its make couple bundle centering good, inspection
Determine resultant error little.
