Description

Technical Field

[0001] This utility model relates to the field of testing equipment, and in particular to a rapid testing fixture for the strength of interfaces between dissimilar materials. Background Technology

[0002] The interface between dissimilar materials is the contact area between two different materials at the connection point. Its performance directly affects the strength, corrosion resistance and long-term stability of the connection. Therefore, it is necessary to use testing fixtures to test the strength of this interface.

[0003] The connection of dissimilar materials often involves the connection between plates or pipes. However, the clamping heads of some existing testing fixtures can only clamp plates and cannot fix tubular materials, which is not practical. At the same time, existing traditional testing equipment can only test by pulling the material in two opposite directions, but this test cannot well simulate the impact when the connection interface is subjected to impact, which is not practical. Therefore, a rapid testing fixture for the strength of the connection interface of dissimilar materials is proposed to solve the above problems. Utility Model Content

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Reference Figures 1-3 This utility model provides an embodiment of a rapid testing fixture for the strength of dissimilar material interface, comprising an operating table 1, which is a dissimilar material interface testing table. Testing mechanisms 2 are provided on both the left and right sides of the operating table 1, which are used to fix the two ends of the dissimilar materials respectively and pull the two ends in opposite directions to test the strength of the dissimilar material interface. An impact mechanism 3 is provided in the center of the top surface of the operating table 1, which is used to repeatedly impact the dissimilar material interface to test its strength. Sliding openings 11 are provided on both the left and right sides of the operating table 1, which are used to cooperate with the movement of a mounting plate 21. The mounting plate 21 is slidably connected to the sliding openings 11. Sliding grooves 12 are provided on both the front and rear sides of the sliding openings 11, which are used to cooperate with the connection of auxiliary blocks 212, thereby restricting the movement direction of the mounting plate 21 so that it can only slide left and right. The auxiliary blocks 212 are slidably connected to the sliding grooves 12.

[0019] Furthermore, the impact mechanism 3 includes two lifting platforms 31, which can be adjusted in height via electric push rods or other means, or the height of the mounting frame 32 can be adjusted via a telescopic frame or other structure. The two lifting platforms 31 are installed on the upper part of the operating platform 1, and the mounting frame 32 is installed on the top of the two lifting platforms 31 together. It is used to cooperate with the installation of the cylinder 33. The cylinder 33 is fixedly connected to the top of the mounting frame 32, which is used to drive the impact hammer 34 to reciprocate, thereby performing impact detection on the interface of dissimilar materials. The air rod of the cylinder 33 passes through and is movably connected to the mounting frame 32. The lower end of the air rod is fixedly connected to the impact hammer 34, which can be made of metal.

[0020] Please see Figures 4-6 As shown, the detection mechanism 2 includes a mounting plate 21, which is used to connect various components. An electric telescopic rod 22 is fixedly connected to the side of the mounting plate 21 away from the impact mechanism 3. This rod is used to drive the connecting plate 25 via a connecting block 23. The telescopic end of the electric telescopic rod 22 passes through and is movably connected to the mounting plate 21. A connecting block 23 is fixedly connected to the end of the electric telescopic rod 22 near the impact mechanism 3. This block is used to connect to the clamping plate 24 via the connecting plate 25. Clamping plates 24 are provided at both the upper and lower parts of the mounting plate 21 near the impact mechanism 3. These clamping plates 24 are used to control the clamping and fixing of materials by the limiting block 26. The two clamping plates 24 are connected... Limiting blocks 26 are fixedly connected to the sides of the two clamping plates 24 that are close to each other. These blocks are used to fix the test material to facilitate the strength test of the connection interface. Fixing blocks 27 are fixedly connected to the sides of the two clamping plates 24 that are close to each other. These blocks are used to facilitate the connection of the connecting plate 25. The fixing blocks 27 and the connecting blocks 23 are movably connected to the connecting plate 25. A hydraulic cylinder 28 is installed at the lower part of the operating table 1. This cylinder is used to move the mounting plate 21, so that the two testing mechanisms 2 can pull the two ends of the dissimilar materials in opposite directions to test the strength of the connection interface of the dissimilar materials. The hydraulic rod of the hydraulic cylinder 28 is fixedly connected to the mounting plate 21.

[0021] Furthermore, a limiting groove 261 is provided on the side of the limiting block 26 near the impact mechanism 3, which is used to limit and fix the tubular material. The width of the limiting groove 261 is half the width of the limiting block 26, so that the limiting block 26 can be used to fix the pipe or the plate. Rubber pads 262 are fixedly connected to the sides of the two limiting blocks 26 that are close to each other for anti-slip. Two connecting grooves 211 are provided on the side of the mounting plate 21 near the impact mechanism 3, which are used to cooperate with the connection and movement of the clamping plate 24. The clamping plate 24 is slidably connected to the connecting grooves 211. Auxiliary blocks 212 are fixedly connected to the front and rear sides of the mounting plate 21 to limit the movement direction of the mounting plate 21.

[0022] Working principle: In use, first place both ends of the dissimilar material to be tested between the two testing mechanisms 2. If it is a tubular material, ensure that both ends of the tubular material are respectively clamped in the limiting grooves 261 opened on the limiting blocks 26 of the two testing mechanisms 2. Activate the electric telescopic rod 22, which will drive the connecting block 23 to move. When the connecting block 23 moves, it will drive the connecting plate 25 connected to it to move. Since the other end of the connecting plate 25 is connected to the clamping plate 24 through the fixing block 27, the connecting plate 25 will drive the two clamping plates 24 to move closer to each other. At this time, the limiting block 26 fixed to the clamping plate 24 will clamp and fix the dissimilar material. Then, the hydraulic cylinder 28 can be activated according to the testing requirements, so that the two hydraulic cylinders 28 push the two testing mechanisms 2 to move in opposite directions, thereby performing tensile testing on the dissimilar material to test the strength of the connection interface.

[0023] Alternatively, after the dissimilar materials are fixed in place by the two testing mechanisms 2, the lifting platform 31 can be opened first to adjust the impact hammer 34 to a suitable height, and then the cylinder 33 can be opened. The cylinder 33 will then drive the impact hammer 34 connected to its lower part to move up and down repeatedly to perform impact testing on the interface of the dissimilar materials in order to test its strength.

[0024] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
