[0035] Example 2

[0036] refer to Figure 1 and Figure 2 The large-capacity double-layer cross three-dimensional guide device of the present invention includes an X-guide rail base plate 1, an X-guide rail 2, an X-slider 3, an X-slider base plate 4, a Y-guide rail base plate 5, a Y-guide rail 6, a Y-slider 7, an X-baffle 8, a Y-baffle 9, an X-adjustment rod 10, a Y-adjustment rod 11, a Y-locking rod 12, a Y-block 13, a Y-fixing block 14 and a bearing beam 15;

[0037] X-direction guide rail 2 is connected to X-direction guide rail base plate 1, X-direction slider 3 is connected to X-direction guide rail 2, and X-direction slider 3 is connected to X-direction slider base plate 4. X-direction slider 3 and X-direction slider base plate 4 can move in the X direction along X-direction guide rail 2. Y-direction guide rail 6 is connected to Y-direction guide rail base plate 5, and Y-direction slider 7 is connected to Y-direction guide rail 6. Y-direction slider 7 and X-direction guide rail base plate 1 can move in the Y direction along Y-direction guide rail 6. A supporting beam 15 is mounted on X-direction slider base plate 4.

[0038] One end of the Y-direction baffle 9 is connected to the Y-direction guide rail base plate 5, and the other end of the Y-direction baffle 9 is connected to the Y-direction adjustment rod 11 to prevent the Y-direction slider 7 from sliding out and separating from the Y-direction guide rail 6. The Y-direction adjustment rod 11 passes through the X-direction slider base plate 4. One end of the X-direction baffle 8 is connected to the X-direction guide rail base plate 1, and the other end of the X-direction baffle 8 is connected to the X-direction adjustment rod 10 to prevent the X-direction slider 3 from sliding out and separating from the X-direction guide rail 2. The X-direction adjustment rod 10 passes through the X-direction guide rail base plate 1. The Y-direction fixing block 14 is fixed to the Y-direction guide rail base plate 5, and the Y-direction stopper 13 is fixed to the Y-direction guide rail base plate 5. The Y-direction locking rod 12 passes through the Y-direction guide rail base plate 5 and the Y-direction fixing block 14.

[0039] like Figure 2 As shown, the three sides of the load-bearing crossbeam 15 are loading surfaces in the X, -X, and Y directions. All three loading surfaces are horizontal and have mounting holes for easy connection to the loading system. During testing, loading can be applied to one of the three loading surfaces of the load-bearing crossbeam 15, or to two mutually perpendicular surfaces, as needed.

[0040] The working process of this utility model is:

[0041] During the test, the bottom end of the specimen is fixed, and the top end of the specimen is connected to the lower surface of the load-bearing beam 15. The load-bearing beam 15 produces corresponding displacement as the specimen deforms, and the X-direction slider 3 and the Y-direction slider 7 produce corresponding displacement along the X-direction guide rail 2 and the Y-direction guide rail 6 respectively. Since the friction between the linear guide sliders is rolling friction, the friction force generated under the action of large force is very small and can be ignored. Therefore, the displacement and test force in the loading direction can be accurately measured and controlled in real time by the displacement sensor and load sensor on the loading system respectively.

[0042] When performing X-direction or -X-direction loading, loosen the nut on the X-direction adjustment rod 10 and tighten the nuts on the Y-direction adjustment rod 11 and the Y-direction locking rod 12 to prevent the loading point from slipping and causing test failure. When performing X-direction or -X-direction and Y-direction coordinated loading, loosen the nuts on the X-direction adjustment rod 10, the Y-direction adjustment rod 11 and the Y-direction locking rod 12. After the test is completed, tighten all the nuts.

[0043] The utility model has the following features:

[0044] 1) Linear guide rails and sliders are used. The linear guide rails have high positioning accuracy, small wear, stable and reliable guidance and long service life.

[0045] 2) It uses double-layer linear guide rails, with the X-guide rail and the Y-guide rail arranged vertically, which can measure displacement in two directions at the same time and is flexible and convenient to use.

[0046] 3) The linear guide slider adopts the rolling friction method. Under the action of large force, the friction force is small and has little effect on the test results.

[0047] 4) Loading interfaces are reserved on the three sides of the load-bearing beam, which provides a wide range of optional loading methods and avoids the singleness of a single loading surface.

[0048] Those skilled in the art will readily conceive of other embodiments of the present invention after considering the specification and disclosure of the utility model. This application is intended to cover any variations, uses, or adaptations of the present invention that follow the general principles of the present invention and include common knowledge or customary techniques in the art not disclosed herein.
