Description

Technical Field

[0001] This utility model relates to the field of acoustic emission sensor fixing technology, specifically a fixing device for acoustic emission sensors. Background Technology

[0002] An acoustic emission sensor is a detection device that converts acoustic emission signals into electrical signals. It is primarily used to monitor the elastic waves generated by materials during deformation or fracture under stress. Its working principle is based on the piezoelectric effect; when subjected to acoustic emission waves, the internal piezoelectric material generates an electric charge, which in turn outputs an electrical signal. It features high sensitivity and rapid response. Widely used in aerospace, petrochemical, and construction industries, it can perform real-time monitoring of structural integrity, detect potential defects and damage in advance, and provide crucial information for ensuring safe equipment operation and preventing accidents.

[0003] When mounting acoustic emission sensors on equipment for testing, the mounting locations vary, resulting in different shapes. For example, when mounting on a cylindrical location, conventionally using magnets for fixation can cause the sensor to shake. Additionally, when fixing equipment using fixing devices, the size of these devices can make fixation inconvenient. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a fixing device for an acoustic emission sensor, including an acoustic emission sensor body. A mounting platform is fixedly connected to the surface of the acoustic emission sensor body. A mounting groove is opened on the front of the mounting platform. A magnet is installed inside the mounting groove. A limiting groove is opened inside the limiting groove. A connecting column is arranged inside the limiting groove. A sliding block is fixedly connected to the surface of the connecting column. A limiting plate is fixedly connected to the front end of the connecting column. A connecting plate is fixedly connected to the rear end of the connecting column. A slot is opened at the rear end of the connecting plate. A threaded rod is sleeved on the surface of the connecting plate. A nut is threadedly connected to the surface of the threaded rod. A pressing plate is sleeved on the surface of the threaded rod. A second nut is threadedly connected to the surface of the threaded rod. A through groove is opened on the surface of the pressing plate.

[0005] Through the above technical solution, this utility model uses a pressing plate to remove the second nut, pulls the pressing plate away from the surface of the threaded rod, and uses a magnet to attract and fix the device to be installed on the acoustic emission sensor body. Then, the pressing plate is sleeved on the surface of the threaded rod and fixed with the second nut. The pressing plate is limited by four bolts. It can fix the acoustic emission sensor body in different shapes and positions. By setting a connecting column, pulling the connecting column causes the sliding block on the surface of the connecting column to slide inside the limiting groove. At the same time, the limiting plate limits one end of the connecting column inside the limiting groove. When the connecting column is pulled out, it drives the threaded rod to move inside the through groove, increasing the distance between the two connecting plates, so as to fix the acoustic emission sensor body in different sizes and positions.

[0006] As a further improvement to the above solution, the mounting platform is located at the rear end of the acoustic emission sensor body.

[0007] With the above technical solution, the mounting platform is located at the rear end of the acoustic emission sensor body. This positional design helps the sensor maintain balance during installation and allows for better coordination with other devices or structures in certain installation scenarios.

[0008] As a further improvement to the above solution, the number of the limiting slide grooves is set to four, and the four limiting slide grooves are evenly distributed symmetrically inside the front of the mounting groove.

[0009] The above technical solution involves setting four limiting grooves, which are symmetrically and evenly distributed inside the mounting groove with respect to the center of the front side. This symmetrical and even distribution ensures that the connecting column is subjected to uniform force in all directions, thereby improving the stability of the entire fixing device. This allows the sensor to maintain a good fixed state when subjected to external forces in different directions, reducing the possibility of shaking and displacement.

[0010] As a further improvement to the above solution, the diameter of the limiting plate is smaller than the diameter of the connecting column, and the surface of the connecting column mounting platform has two sliding blocks, which are symmetrically and evenly distributed on the surface with respect to the top center of the connecting column.

[0011] With the above technical solution, the diameter of the limiting plate is smaller than the diameter of the connecting column. The connecting column is installed on the surface of the mounting platform. The sliding blocks are symmetrically and evenly distributed on the surface with respect to the top center of the connecting column. The diameter of the limiting plate is smaller than the diameter of the connecting column, which limits the connecting column inside the limiting groove. The symmetrical distribution of the two sliding blocks helps the connecting column slide stably in the limiting groove.

[0012] As a further improvement to the above solution, the threaded rod passes through both ends of the connecting plate, and the nut is engaged inside the slot.

[0013] As a further improvement to the above solution, the threaded rod passes through both ends of the pressing plate.

[0014] With the above technical solution, the threaded rod passes through both ends of the pressing plate, which helps to stably install the pressing plate on the threaded rod, so that the pressing plate can be evenly stressed when fixing the sensor, and better fit with the sensor surface, thereby achieving a stable fixing effect.

[0015] As a further improvement to the above solution, the threaded rod passes through the through groove.

[0016] Through the above technical solution, the threaded rod passes through the through groove. This design allows the position of the pressing plate on the threaded rod leg to be adjusted according to actual needs.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] This invention uses a pressing plate to remove the second nut, pull the pressing plate out from the surface of the threaded rod, and use a magnet to attract and fix the device to be installed with the acoustic emission sensor body. Then, the pressing plate is sleeved on the surface of the threaded rod and fixed with the second nut. The pressing plate is limited by four bolts, which can fix and install the acoustic emission sensor body in different shapes and positions.

[0019] This invention features a connecting column. When the connecting column is pulled, the sliding block on the surface of the connecting column slides inside the limiting groove. At the same time, the limiting plate limits one end of the connecting column inside the limiting groove. When the connecting column is pulled out, the threaded rod moves inside the through groove, increasing the distance between the two connecting plates. This allows for fixing the acoustic emission sensor body at different sizes and positions. Attached Figure Description

[0029] Mounting platform 2 is located at the rear end of acoustic emission sensor body 1.

[0030] There are four limiting slide grooves 5, which are symmetrically and evenly distributed inside the front center of the mounting groove 3.

[0031] The diameter of the limiting plate 8 is smaller than the diameter of the connecting column 6. There are two sliding blocks 7 on the surface of the mounting platform 2 of the connecting column 6. The two sliding blocks 7 are evenly distributed on the surface symmetrically with respect to the top center of the connecting column 6.
