[0027] The utility model provides a technical solution: Figure 1-2 As shown, a simple acoustic emission sensor fixing device comprises a base plate 1, an acoustic emission sensor 3, and a cross-centered transparent film 14. A center hole 2 is opened at the center of the base plate 1, and the acoustic emission sensor 3 is inserted into the center hole 2. A mounting mechanism 4 is provided on the top of the base plate 1;
[0028] like Figure 3 and Figure 5 As shown, the mounting mechanism 4 includes a collar 401, a first reinforcement ring 406, and a mounting groove 407. The mounting groove 407 is provided at the top of the base plate 1. The collar 401 is movably mounted on the acoustic emission sensor 3. The top inner wall of the collar 401 is pressed on the top of the acoustic emission sensor 3. The outer wall of the collar 401 is fixedly mounted with a mounting plate 402. The mounting plate 402 is clamped in the mounting groove 407. A threaded hole 405 is provided on the bottom inner wall of the mounting groove 407. A fixing piece 403 is threadedly connected to the inner wall of the mounting plate 402. The bottom end of the fixing piece 403 is threadedly connected to the inner wall of the threaded hole 405. An avoidance groove 404 is provided on the side outer wall of the collar 401. The avoidance groove 404 corresponds to the cable connection end on the acoustic emission sensor 3.
[0029] In some embodiments, Figure 3As shown, the first reinforcement ring 406 is fixedly installed in the center hole 2, and the first reinforcement ring 406 is slidably mounted on the acoustic emission sensor 3, the base plate 1 is bonded to the small component with glue, and then the acoustic emission sensor 3 is installed in the center hole 2, the acoustic emission sensor 3 is fixed by pressing the ring 401 on the acoustic emission sensor 3, the mounting plate 402 is fixedly connected to the base plate 1 by the fixing member 403, and then the ring 401 is fixedly connected to the base plate 1. During the installation process, there is no need to perform operations such as opening holes on the outer surface of the acoustic emission sensor 3 for installation, and there is no need to use glue to bond the acoustic emission sensor 3 to avoid damage to the acoustic emission sensor 3. An avoidance groove 404 is provided so that the cable connection end on the acoustic emission sensor 3 can extend from the ring 401, and the first reinforcement ring 406 is provided to press and limit the base plate 1 to prevent the acoustic emission sensor 3 from tilting in the center hole 2 when the ring 401 is installed on the base plate 1.
[0030] A second reinforcement ring 15 is fixedly mounted on the inner wall of the central hole 2 . The second reinforcement ring 15 is slidably mounted on the acoustic emission sensor 3 . An outer wall of the second reinforcement ring 15 facing the acoustic emission sensor 3 is provided with an integrally formed anti-slip protrusion 16 .
[0031] In some embodiments, Figure 3-4 As shown, the acoustic emission sensor 3 is limited by the anti-slip protrusions 16 on the second reinforcement ring 15 to prevent the acoustic emission sensor 3 from rotating.
[0032] Optionally, the first reinforcement ring 406 and the second reinforcement ring 15 are both rubber rings.
[0033] In some embodiments, Figure 3 As shown, a gasket 7 is provided between the fixing member 403 and the mounting plate 402 to prevent the fixing member 403 from loosening due to external vibration, and a rubber pad 8 is provided between the top inner wall of the ring 401 and the top of the acoustic emission sensor 3.
[0034] This prevents the rigid collar 401 from causing damage to the acoustic emission sensor 3 when it is pressed on the top of the acoustic emission sensor 3 .
[0035] In some embodiments, Figure 5 As shown, the outer diameter of the cross-centering transparent film 14 is consistent with the inner diameter of the mounting groove 407. The cross-centering transparent film 14 is a rigid film, which is made by depositing ITO on a glass substrate.
[0036] When the base plate 1 is bonded to the small component, the installation point on the small component is positioned by the cross-centering transparent film 14, thereby ensuring that the center of the center hole 2 is aligned with the installation point. A rigid cross-centering transparent film 14 is used to ensure that the cross-centering transparent film 14 will not bend or deform when placed in the installation groove 407, thereby ensuring that the center of the cross-centering transparent film 14 can be aligned with the center of the center hole 2.
[0037] In some embodiments, Figure 3 As shown, a connecting frame 11 is slidably sleeved on the outer wall of the bottom plate 1, a through groove 9 is opened on the side outer wall of the bottom plate 1, an ejection hole 10 is opened on the bottom inner wall of the mounting groove 407, and the ejection hole 10 is communicated with the through groove 9, a connecting plate 12 is fixedly installed on the inner side of the connecting frame 11, and the connecting plate 12 is slidably set in the through groove 9, and an ejection rod 13 is fixedly installed on the top of the connecting plate 12, and the ejection rod 13 is slidably set in the ejection hole 10.
[0038] By moving the connecting frame 11 upward, the connecting plate 12 is driven upward, and then the ejection rod 13 is driven upward to eject the cross-centering transparent film 14 from the installation groove 407, so as to avoid the problem that there is no gap between the cross-centering transparent film 14 and the inner wall of the installation groove 407, which makes it inconvenient to take out the cross-centering transparent film 14;
[0039] In some embodiments, Figure 1 As shown, a sawtooth groove 5 is provided at the bottom of the bottom plate 1, and the sawtooth groove 5 is provided for the flow of glue and can increase the contact surface between the bottom of the bottom plate 1 and the glue. That is, after aligning the bottom plate 1 with the installation point, it is only necessary to squeeze the glue into the sawtooth groove 5. Figure 2 As shown, an integrally formed stop ring 6 is provided at the bottom of the base plate 1 , and the stop ring 6 separates the serrated groove 5 from the center hole 2 . The stop ring 6 is provided to prevent glue from flowing into the center hole 2 , thereby preventing the glue from adhering to the acoustic emission sensor 3 .
[0040] When in use, place the cross-centering transparent film 14 in the installation groove 407, place the bottom plate 1 on the installation point, align the center of the cross-centering transparent film 14 with the center of the installation point, and then squeeze the glue into the serrated groove 5. After the glue solidifies and fixes the bottom plate 1 and the small component together, pull up the connecting frame 11 to drive the connecting plate 12 to move up, and then drive the ejection rod 13 to move up, and eject the cross-centering transparent film 14 from the installation groove 407. The cross-centering transparent film 14 can be recycled and reused. The acoustic emission sensor 3 is vertically inserted into the center hole 2, and then the ring 401 is put on the acoustic emission sensor 3. When putting on the ring 401, the avoidance groove 404 is aligned with the cable connection end on the acoustic emission sensor 3, and then the fixing piece 403 is used to fix the mounting plate 402 in the mounting groove 407 to complete the installation of the acoustic emission sensor 3. After use, it is only necessary to use a tool to unscrew the fixing piece 403, and then pull up the ring 401 to remove it, and then the acoustic emission sensor 3 can be pulled out of the center hole 2 for secondary use.
[0041] Based on the embodiments of the present utility model, all other embodiments obtained by ordinary technicians in the field without making any creative work shall fall within the scope of protection of the present utility model.
