Acceleration sensor assembly and acceleration sensor mounting method

Abstract

The invention discloses an acceleration sensor assembly and an acceleration sensor mounting method. The acceleration sensor assembly comprises an acceleration sensor, a steel wire, a waveform gasket,a special-shaped gasket and an installation boss. The acceleration sensor comprises a main body part, a shell coating the main body part, and a mounting bolt. At least one set of through holes are formed in the shell, and a steel wire fixing mechanism is arranged on the special-shaped gasket. The installation boss is provided with a threaded hole matched with the installation bolt and an installation face matched with the special-shaped gasket. The locking steel wire is fixed through the special-shaped gasket and the steel wire fixing hole, and when the acceleration sensor is screwed down, thespecial-shaped gasket is buffered and pressed through the elastic waveform gasket, so that the steel wire can be locked, looseness prevention of the sensor is achieved, and stable and reliable measurement data are obtained.

Description

technical field [0001] The invention relates to the technical field of sensors, in particular to an acceleration sensor component and an acceleration sensor installation method. Background technique [0002] Piezoelectric acceleration sensors are widely used in industrial monitoring, transportation, test and measurement and other fields, and have the characteristics of good reliability, high signal-to-noise ratio, and good frequency response. The piezoelectric acceleration sensor uses the piezoelectric effect of the crystal to complete the vibration measurement. When the measured body vibrates, it is transmitted to the sensor. The inertial mass Mass will generate pressure on the crystal Crystal, and the crystal element will generate charges. The charge is passed through the Charge converter. Converted into corresponding vibration parameters, so as to realize the measurement of vibration acceleration. In order to ensure the stable and reliable performance of the acceleration...

Problems solved by technology

However, when the acceleration sensor is installed in a specific vibration environment, the thread glue cannot meet the reliability requirements; the working principle of the anti-loosening gasket is usually to use elastic deformation to generate pressure, and then increase friction to prevent loosening. However, through the test Verify that the elastic deformation produced in this way will directly affect the performance of the acceleration sensor

[0003] Therefore, in view of the technical problem that the thread glue in the above-mentioned prior art cannot meet the requirements of the stability and reliability of the acceleration sensor installed in the vibration environment, and the anti-loosening gasket directly affects the performance of the acceleration sensor, it is necessary to conduct research and development to provide a solution , to achieve a stable installation of the acceleration sensor
