Description

Technical Field

[0001] The utility model relates to the technical field of mechanical property testing, and more specifically, to a soft connection mechanical property testing device. Background Art

[0002] In the industrial field, especially for various equipment and structural components in the field, it is often necessary to test their mechanical properties to ensure the safety and reliability of use. Although the traditional portable indentation mechanical property tester can meet the testing requirements under various working conditions, its testing often relies on specific tooling to ensure that the tester can be stably fixed directly above the specimen to be tested and provide sufficient pre-tightening force to prevent loosening during the testing process, thereby avoiding damage to the indenter.

[0003] Although the metal hard connection tooling currently used on the market can meet the testing requirements in most cases, due to the high requirements of these tooling for the testing environment, such as requiring a large space and a relatively regular testing surface, when encountering specimens with complex shapes or narrow spaces, these hard connection metal tooling are often not applicable. To address the problems in the related art, no effective solution has been proposed yet. Summary of the Utility Model

[0004] To address the problems in the related art, the utility model proposes a soft connection mechanical property testing device to overcome the above-mentioned technical problems existing in the existing related art.

[0005] For this purpose, the specific technical solution adopted by the utility model is as follows:

[0006] A soft connection mechanical property testing device includes a mechanical property tester body. A coordinate slider is fixedly installed at the bottom of the mechanical property tester body. A test adjustment mechanism is provided inside the coordinate slider. Connecting blocks are fixedly installed on both sides of the surface of the coordinate slider. One end of each connecting block is threadedly connected with a locking screw. One side of the surface of the locking screw is threadedly connected with a U-shaped plate. Both ends of the U-shaped plate are fixedly connected with buckle straps through bolts. An aramid webbing is fixedly installed inside the buckle straps. A V-shaped block is fixedly installed on the surface of the aramid webbing. Positioning magnetic columns are fixedly installed on both sides of the surface of the V-shaped block.

[0007] Further, to adjust the position of the test point of the mechanical property tester body, the test adjustment mechanism includes a support plate slidably installed on the surface of the coordinate slider. One side of the support plate is fixedly connected with a transmission plate. A transmission lead screw is threadedly connected to the surface of the transmission plate. Positioning blocks one are fixedly connected to both sides of the surface of the coordinate slider. The transmission lead screw is rotatably connected to the positioning blocks one. An adjustment plate is slidably installed on the surface of the support plate. One side of the surface of the adjustment plate is rotatably installed with an adjustment bolt. A positioning block two is fixedly connected to one side of the support plate. The adjustment bolt is threadedly connected to the positioning block two.

[0008] Further, in order to fix both ends of the aramid webbing on one side of the buckle, outer clamping plates are provided at both ends of the aramid webbing. A middle clamping plate is fixedly installed on one side of the outer clamping plate through bolts, and an inner clamping plate is fixedly installed on one side of the middle clamping plate through bolts.

[0009] Further, in order to position the V-shaped blocks on the aramid webbing, wave beads screws are threadedly connected to both sides of the surface of the V-shaped blocks.

[0010] Further, in order to fixedly install the mechanical property tester body, threaded holes are opened on both sides of the surface of the adjusting plate, and the mechanical property tester body is fixedly installed on the adjusting plate through bolts.

[0011] Further, in order to increase the clamping friction force between the middle clamping plate and the outer clamping plate and the inner clamping plate respectively, anti-slip patterns are provided on both sides of the surface of the middle clamping plate.

[0012] Further, in order to facilitate the screwing and adjustment of the transmission lead screw and the adjusting bolt, screwing heads are fixedly installed at one end of both the transmission lead screw and the adjusting bolt.

[0013] The beneficial effects of the present utility model are as follows: By using the aramid webbing as a connecting piece to fix the mechanical property tester body on the structure to be tested, the device can adapt to more diverse test environments, can effectively perform tests on specimens with narrow spaces or complex shapes, improving the flexibility and applicability of the tests; and through the design of the magnetic columns built into the V-shaped blocks on the aramid webbing, the test device can be easily adsorbed on the test surface, greatly simplifying the installation process, and a single person can achieve the installation and test operations.
