Following present a kind of structural schematic diagrams of Fluid pressure loading device.
Referring to Figure 2, Fig. 2 is the structural representation of Fluid pressure loading device in a kind of specific embodiment of the present invention
Figure；Wherein, both direction load is illustrated only in Fig. 2, vertically and horizontally.
Specifically, Fluid pressure loading device 4 includes ontology 41 in a specific embodiment, is offered inside ontology 41
Sample accommodating cavity 4a, at least one fluid media (medium) chamber, sample accommodating cavity 4a is for accommodating and fixing sample；Each fluid media (medium) chamber
Inside is equipped with piston, and corresponding fluids dielectric cavity is isolated into two chambers by piston, wherein a chamber inside ontology 41 by setting
The oil communication external hydraulic medium set, another chamber sample accommodating cavity 4a, and each piston are towards sample accommodating cavity 4a
One end can extend to inside sample accommodating cavity 4a；Fluid media (medium) chamber and piston form load cylinder.
Sample is placed in the inside of the ontology 41 of loading device when carrying out power load to sample by the embodiment first,
Then fluid media (medium) is filled to the intracavitary portion of fluid media (medium) inside ontology 41 in driving external agency source, in incoming fluid dielectric cavity fluid
Under the promotion of medium, the piston for being placed in the intracavitary portion of fluid media (medium) is mobile towards sample accommodating cavity 4a, with the continuous note of fluid media (medium)
Enter, piston is against sample and applies certain power in sample.Operator can be according to the pressure of fluid media (medium), piston in pipeline
The power that area, calculating are applied on sample, to realize the load of sample power.
The sample power loading method provides the pressure of different directions by embedded load cylinder, by taking liquid medium as an example, pressure
Power can achieve 200MPa, and can realize three axis, two axis, uniaxial loading test, and loading device is relatively simple for structure, and volume can

Dividing, which does not influence ray, penetrates, for size without particular/special requirement.
In addition, for X, the load of Y both direction under the premise of guaranteeing loading force size, will also reduce as far as possible ray and wear
The influence generated when thoroughly to sample, therefore the outer dimension of ontology 41 wants sufficiently small, but it has to be ensured that its experiment load, because
This work in-process, ontology 41 use asymmetrical loading mode, i.e., in longitudinal section, the wall of fluid media (medium) chamber side is arranged in ontology 41
Thickness is greater than the wall thickness of opposite side.It can also be seen that 41 thickness of ontology of the setting side first fluid dielectric cavity 4b is greater than phase from Fig. 2
The thickness of opposite side ontology 41.
Fabrication hole 4c, the radial dimension of the fabrication hole 4c are additionally provided on ontology 41 opposite with fluid media (medium) chamber simultaneously
Less than the radial dimension of fluid media (medium) chamber, fabrication hole 4c can reduce the difficulty of processing of fluid media (medium) chamber.Certainly, it is real to carry out power load
When testing, fabrication hole 4c is needed with blocking.
In addition, in order to ensure fluid media (medium) cavity wall machining accuracy, in order to guarantee influence of the loading oil circuit to ray, connection
The hydraulic fluid port of external hydraulic medium is all set in the upper surface of ontology 41, is connected to each fluid media (medium) chamber by inner passage, using
Vent line is directly processed in ontology, it in this way can be to avoid the influence because of external oil pipe to ray.
For the ease of sample from the inside for being arranged in sample accommodating cavity 4a outside, ontology 41 is additionally provided with connection lower surface and institute
The channel 4e of sample accommodating cavity 4a is stated, so that the sample is placed in from the channel 4e inside of the sample accommodating cavity 4a, and
And the arrival end of channel 4e is additionally provided with blocking.
For the ease of the installation and assembly of ontology 41, flange can also be arranged in the upper and lower ends portion of ontology 41, and connector is logical
Cross the flange for being bolted 41 both ends of ontology.Lower end is that first flange 43 and the first connector 46 are cooperatively connected, upper end
It is cooperatively connected for second flange 47 and the second connector 45.Connecting hole can be set on connector, flange, bolt passes through the two
Connecting hole is fixed with attaching nut, to realize the connection of connector and flange.It gives in Fig. 2 and is connected on the second connector 45
Hole 45a.
In addition, it is also provided with seal member therebetween in order to guarantee the sealing between piston and fluid media (medium) chamber,
Seal member can be sealing ring, be machined with mounting groove on the peripheral wall of piston, sealing ring is placed in the inside of mounting groove.
