Abstract
The invention provides a pressurizing plate. The pressurizing plate comprises a pressurizing surface and a pressure applying surface, wherein a plurality of pressurizing beams are arranged between the pressurizing surface and the pressure applying surface, so that the force transmitting direction of the pressurizing beams is consistent with the pressurizing direction of the pressurizing surface; flexible packing is fixedly connected between the adjacent pressurizing beams, so that the problem of low precision in a triaxial testing process in the prior art is solved. Thus, when a sample is axially deformed, a pressurized plate can be deformed axially as the axial deformation of the sample without affecting the applied force to a sensor. The precision and reliability of measured data are improved.

Embodiment
Below in conjunction with accompanying drawing of the present invention, technical scheme of the present invention is clearly and completely described, obviously, described embodiment is only the present invention's part embodiment, rather than whole embodiment.Embodiment based in the present invention, those of ordinary skills, not making the every other embodiment obtaining under creative work prerequisite, belong to the scope of protection of the invention.
As shown in Figure 1, 2, when the increased pressure board 10 in one embodiment of the present invention is applied to three axle test machines 20, be assemblied in three axle test machines 20 two lateral stresses (σ 2, σ 3) actuator 21 and sample 30 between, when sample 30 being carried out to stress detection, actuator 21 applies lateral stress by 10 pairs of samples 30 of increased pressure board.The side that increased pressure board 10 contacts with actuator 21 is for adding pressure surface 11, and the side contacting with sample 30 is the face of exerting pressure 12.Adding the pressurization beam 40 that a plurality of parallel metal materials are set between pressure surface 11 and the face of exerting pressure 12, the power transmission direction of its pressurization beam 40 is consistent with the compression aspect that adds pressure surface 11.Between adjacent pressurization beam 40, by modes such as bonding or hot melts, fill fixing flexible filler 50.The metal material of above-mentioned pressurization beam 40 can be preferably stainless steel, high-quality stainless steel, alloy steel or alloy aluminum material.The material of flexible filler 50 can select the materials such as more yielding polyurethane to make.Thereby when actuator 21 is during to the adding pressure surface 11 and apply side force of increased pressure board 10, pressurization beam 40 is by this lateral forces on the face of exerting pressure 12, and the face 12 of exerting pressure puts on this side force on sample 30, thereby realize, the side force of sample 30 is applied.Follow-uply by 22,23 pairs of samples 30 of axial actuator, apply axial force, if now sample 30 produces axial deformations, flexible filler 50 also can produce axial deformation thereupon.Therefore, the present invention, when sample is applied to multi-direction stress, does not hinder the axial deformation of sample, thereby, improved the precision and the reliability that detect data.
As shown in Figure 1, 2.In one embodiment of the invention, the cross sectional shape of pressurization beam 40 can be preferably " work " shape.Thereby make to pressurize beam 40 when bearing side force, can guarantee effective side force transmission, improved the reliability of application of force process.What specify is that above-mentioned pressurization beam 40 can adopt the structure that be arranged in parallel in diagram, and what also can adopt multi-angle arranges structure (not shown) simultaneously.
For making increased pressure board 10 in use, to add the side force of pressure surface 11 apply more steady, in one embodiment of the invention, as shown in Figure 3, in the outside that adds pressure surface 11 of increased pressure board 10, also arrange outside force application board 60.The material of this outside force application board 60 can be preferably stainless steel or aluminum alloy materials.This outside force application board 60 with add pressure surface 11 and can adopt multiple connected mode to be fixed to be connected or to be flexibly connected, being wherein fixedly connected with modes such as can adopting welding, grafting or bolt connection and connecting.In one embodiment of the invention, for making sample 30 more flexible in axial movement, as shown in Figure 4, outside force application board 60 also can be flexibly connected by rolling bearing 70 with adding between pressure surface 11.Its rolling bearing 70 can be preferably needle bearing.When connecting, the inner ring of rolling bearing 70 can be fixedly connected with outside force application board 60, its outside force application board 60 and increased pressure board 10 can additional fixed covers, thereby that realizes increased pressure board 10 adds the relative fixing of pressure surface 11 and rolling bearing 70, and can make rolling bearing 70 outer ring can with add pressure surface 11 and produce and endwisely slip.Thereby, when sample 30 is in wanting application of force stage or the application of force during stage, more flexible with respect to endwisely slipping of outside force application board 60, thus make the measurement of survey sensor more accurate.In such scheme, for making rolling bearing 70 more steady with being connected of outside force application board 60, in one embodiment of the invention, as shown in Figure 5, outside force application board 60 is also offered " V " shape bearing groove 61 with the fixation side of rolling bearing 70.
For making increased pressure board 10 more simple and easy in process, cost is lower (, reduce the pressurization flatness of beam 40 and the processing cost of high consistency), and the side force of sample 30 is applied more even, in one embodiment of the invention, as shown in Figure 6, increased pressure board 10 is epimere increased pressure board 101 and hypomere increased pressure board 102, between epimere increased pressure board 101 and hypomere increased pressure board 102, can connect by multi-activity connected modes such as hinge, grafting or guide rails.
For the increased pressure board 10 in the present invention can length according to actual needs be regulated, in one embodiment of the invention, as shown in Figure 7, at the sidewall of a plurality of pressurization beams 40, offer and run through through hole 41, assembly connection bar 80 in through hole 41, the external diameter of this connecting link 80 is corresponding with through hole 41 diameters, thereby a plurality of pressurization beam 40 can be fixed connection by connecting link 80.Particularly when needs combine multistage increased pressure board, length that can be according to actual needs, combines existing increased pressure board 10.Between one end of its connecting link 80 and pressurization beam 40 for screw thread is fixedly connected with, thereby convenient to adding end from a side installation.For making the face of exerting pressure 12 of increased pressure board 10 more tight with contacting of sample 30, in one embodiment of the invention, the flexible damping sheet 90 of docile also in the face of exerting pressure 12 outsides.Thereby reduced collecting together between the face of exerting pressure 12 and sample 30, it is more accurate to make to measure.
Hence one can see that, and beneficial effect of the present invention is, owing on the pressurization vertical plane at increased pressure board, flexible filler being set, therefore, when sample produces axial deformation, pressing plate can synchronously produce axial deformation with the axial deformation of sample, thereby can not affect the application of force to sensor.Precision and the reliability of measurement data have been improved.
The above; be only the specific embodiment of the present invention, but protection scope of the present invention is not limited to this, is anyly familiar with those skilled in the art in the technical scope that the present invention discloses; can expect easily changing or replacing, within all should being encompassed in protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion by the described protection domain with claim.
