Description

Technical Field

[0001] This utility model relates to the field of digital vibration sensor technology, and more specifically, it relates to a magnetically attached triaxial high-frequency digital vibration sensor. Background Technology

[0002] In industrial production, compressors are crucial equipment, and their operating status directly affects production efficiency and product quality. Vibration testing is a common quality inspection method to ensure the normal operation of compressors. By analyzing the vibration signals generated during compressor operation, potential problems such as imbalance and bearing wear can be detected in a timely manner, thereby preventing malfunctions.

[0003] Currently, triaxial high-frequency digital vibration sensors are commonly used to detect compressor vibration. These sensors can simultaneously measure vibration signals in three directions, providing comprehensive vibration data. However, in actual testing, there are some issues with the sensor's installation. Common installation methods include bolt-nut connections, screw connections, or other fastening structures. These methods are relatively complex, requiring precise positioning and fixing by operators, and the installation process is time-consuming, resulting in low testing efficiency.

[0004] Furthermore, traditional installation methods may be limited by the surface shape and material of the compressor, further increasing the difficulty of installation. For example, on some complex compressor structures, bolts or screws may not be able to be installed directly, requiring additional fixing devices or structures to ensure the stability of the sensor. This complexity not only prolongs the installation time but may also affect the measurement accuracy of the sensor.

[0005] Therefore, the existing installation methods for compressor vibration detection sensors have problems such as complex installation, long installation time, and low efficiency. There is an urgent need for a simpler and more efficient installation method to improve detection efficiency. Utility Model Content

[0025] Please see Figure 1-4 A magnetically attached triaxial high-frequency digital vibration sensor includes a sensor body 1, a mounting bracket 2, and an adsorption mechanism 3. The mounting bracket 2 is fixed to the sensor body 1, and the adsorption mechanism 3 is mounted on the mounting bracket 2. The adsorption mechanism 3 includes an electromagnet assembly 31, which is used to adsorb the compressor, thereby fixing the sensor body 1 to the compressor. The adsorption mechanism 3 also includes an adsorption block 32 adapted to the compressor. There is a connector 33 between the electromagnet assembly 31 and the adsorption block 32 for connecting the two. The adsorption block 32 has a mating surface 322 adapted to the compressor profile.

[0026] In practical applications, the sensor body 1 can be suspended above the workstation to be tested by means of a sling. When the compressor is moved into place, the sensor body 1 is slowly lowered by the sling structure, and the electromagnet assembly 31 is activated. The electromagnet assembly 31 and the adsorption block 32 adsorb the compressor, thereby fixing the sensor body 1 on the compressor and completing the connection between the sensor body 1 and the compressor. Then, the vibration performance of the compressor can be detected by the sensor body 1.

[0027] In this embodiment, please refer to Figure 1-4The electromagnet assembly 31 includes an electromagnet body 311 and a first connecting block 312 fixed on the electromagnet body 311. A second connecting block 321 is fixed on the adsorption block 32. The first connecting block 312 and the second connecting block 321 are connected by a connector 33. The first connecting block 312 and the second connecting block 321 are respectively provided with a first snap-fit ​​groove 3121 and a second snap-fit ​​groove 3211. The connector 33 is engaged with the first snap-fit ​​groove 3121 and the second snap-fit ​​groove 3211. The cross-section of the connector 33 is I-shaped. A positioning pin 3122 is fixed on the side of the first connecting block 312 that is in contact with the second connecting block 321. A positioning hole 3212 that cooperates with the positioning pin 3122 is provided on the second connecting block 321.

[0028] In practical applications, the electromagnet body 311 is fixed on the mounting bracket 2. The electromagnet body 311 and the adsorption block 32 are connected and fixed by the first connecting block 312, the second connecting block 321 and the connector 33. During installation, the second connecting block 321 is first attached to the lower surface of the first connecting block 312, and the positioning pin 3122 is matched with the positioning hole 3212. Finally, the connector 33 is inserted into the first snap-fit ​​groove 3121 and the second snap-fit ​​groove 3211 to complete the connection and fixation between the first connecting block 312 and the second connecting block 321.

[0029] In this embodiment, the second connecting block 321 is also provided with a pressure relief hole 3213, and the pressure relief hole 3213 connects the bottom of the positioning hole 3212 with the external space.

[0030] In practical applications, during the process of inserting the positioning pin 3122 into the positioning hole 3212, the air inside the positioning hole 3212 is discharged from the pressure relief hole 3213, so as to avoid the positioning pin 3122 not being able to be fully inserted into the positioning hole 3212 due to the high pressure inside the positioning hole 3212.

[0031] In all the solutions mentioned above, although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
