Property.
As depicted in figs. 1 and 2, clamping device may include connector 4 and the clamping piece connecting with connector 45, and connector
4 and clamping piece 5 be respectively positioned on except heating chamber 212.Wherein:
Connector 4 is mountable on mechanics test device 1, for connecting mechanics test device 1 and clamping piece 5.Such as preceding institute
State, mechanics test device 1 may include pedestal and moving portion, then the quantity of connector 4 can be two, a connector 4 with it is upper
Pedestal connection is stated, another connector 4 is connect with above-mentioned moving portion, and the mode of connection can be threaded connection or clamping etc., this
Place is not particularly limited.For example, connector 4 can be the structures such as round bar, will not enumerate herein.
As shown in Figures 2 and 3, clamping piece 5 is for clamping test specimen 3 to be measured, and the quantity of clamping piece 5 is two, two folders
Gripping member 5 is oppositely arranged, and is connected to two connectors 4 correspondingly, and the connection type of clamping piece 5 and connector 4 can be
It is threadedly coupled, welds or is clamped, be not particularly limited herein.
The clamping piece 5 of disclosure embodiment may include the first clamping part 50, the second clamping part 51 and interconnecting piece 52, first
Clamping part 50 and the second clamping part 51 are oppositely arranged, and the first clamping part 50 and the second clamping part 51 are connected with interconnecting piece 52.
For example, the first clamping part 50, the second clamping part 51 and interconnecting piece 52 can have arc outer edge, certainly,
The outer edge of first clamping part 50, the second clamping part 51 and interconnecting piece 52 can also for planar shaped or other, do not make special limit herein
It is fixed.
The clamping piece 5 of disclosure embodiment may also include the first limiting section 54 and the second limiting section 55, the first limiting section
54 and second limiting section 55 be oppositely arranged, and the first limiting section 54, the second limiting section 55, the first clamping part 50 and the second clamping part
51 successively join end to end, and form holding chamber 53.
Wherein, one end of the first limiting section 54 may connect to the first clamping part 50, and the other end may connect to the second clamping part
51, the mode of connection can be threaded connection etc., be not particularly limited herein.The fixed form of second limiting section 55 can be with first
Limiting section 54 is identical, and details are not described herein again.Moreover, the first limiting section 54 and the second limiting section 55 at least one with the first clamping part
50 and second clamping part 51 it is detachable, to guarantee that test specimen 3 to be measured can be sticked in holding chamber 53 from the side of holding chamber 53.It is preferred that
Ground, the first limiting section 54 and the second limiting section 55 are detachable, to facilitate the operation of test.
It should be noted that the size of holding chamber 53 and the size of test specimen to be measured 3 are corresponding.As shown in figure 4, because aviation
The test specimen to be measured 3 for being used to make the ceramic matric composite of engine turbine blade in industry is usually that both ends size is big, intermediate
Size is small, so the size of holding chamber 53 is gradually reduced from one end close to interconnecting piece 52 to one end far from interconnecting piece 52,
That is the distance between the first clamping part 50 and the second clamping part 51 are from one end close to interconnecting piece 52 to far from interconnecting piece 52
One end be gradually reduced so that test specimen to be measured 3 can be sticked in holding chamber 53.It, first will be in the preparation process of test
Test block 3 is fastened between the first clamping part 50 and the second clamping part 51, and fixes the first limiting section 54 and the second limiting section 55,
So that test specimen 3 to be measured can be securely fastened in holding chamber 53.
Certainly, the both ends size of test specimen 3 to be measured can also be identical with in-between size, then the shape of clamping piece 5 is not for another example
It is described above.For example, mounting hole can be opened up in the end positions of the identical test specimen 3 to be measured of both ends size and intermediate sizes,
And clamping piece 5 can have the clamping portion with mounting hole cooperation, and the clamping of test specimen 3 to be measured can also be realized by the clamping portion, this
Place is not described in detail.
For example, the first limiting section 54 and the second limiting section 55 may each comprise fixed plate 540 and protrusion 541, in which:
Fixed plate 540 can be arc panel, which can have outer peripheral first clamping part of arc with above-mentioned
50 and second clamping part 51 fit, and be connected between the first clamping part 50 and the second clamping part 51.Certainly, fixed plate 540
It may be plate, at this point, the first clamping part 50 and the second clamping part 51 have planar portions, the planar portions and flat fixation
Plate 540 fits, to realize the connection of fixed plate 540 and the first clamping part 50 and the second clamping part 51.
Protrusion 541 can be set to fixed plate 540 close to the side of interconnecting piece 52, when test specimen 3 to be measured is sticked in holding chamber 53,
Protrusion 541 can contact and contact test specimen 3 to be measured, so that test specimen to be measured 3 can more tightly be fastened on holding chamber 53.
Because the connector 4 and clamping piece 5 of clamping device are respectively positioned on except heating chamber 212, it is no longer necessary to bear high temperature ring
Border, so connector 4 and clamping piece 5 can be used, cost is relatively low and the preferable metal material production of thermal diffusivity, compared to existing skill
SiC (silicon carbide) ceramics used in art, can reduce the cost of test.
For example, which can be high temperature alloy, be waited for using being used to clamp high temperature made of the high temperature alloy
The clamping piece 5 of test block 3 is notheated deformation, is also avoided that and causes clamping piece 5 because of the unpredictalbe preparation defect of SiC ceramic
The problem of poor reliability.In addition, after the end of the test, it also can be shorter using the connector 4 and clamping piece 5 of high temperature alloy manufacture
Time in heat dissipation, and then shorten the period of test.
The high-precision ultra-temperature mechanical performance test macro of disclosure embodiment may also include controller, the controller and
The driving portion and heating device 2 of above-mentioned mechanics test device 1 connect, and treat the application of test block 3 with control mechanics test device 1
The size and Orientation and heating device 2 of load treat the rate of heat addition and heating temperature of test block 3.The work of the controller
Process can be carried out by preset program or related software, be not described in detail herein.
Those skilled in the art after considering the specification and implementing the invention disclosed here, will readily occur to its of the disclosure
Its embodiment.This application is intended to cover any variations, uses, or adaptations of the disclosure, these modifications, purposes or
