Acceleration sensor base with checking and calibration mechanism

Abstract

The invention relates to an acceleration sensor base with a checking and calibration mechanism. The acceleration sensor base is provided with a vibration plate, a main driving shaft and a speed adjusting motor, wherein the vibration plate is used for transferring vibration amplitude and frequency to an acceleration sensor, the main driving shaft is used for generating vibration amplitude, the speed adjusting motor is used for generating vibration frequencies, a step shaft is arranged on the main driving shaft and has different eccentric distance from the main driving shaft, the main driving shaft is connected with the speed adjusting motor, the eccentric step shaft is connected with a vibration rod through a roller, the upper end of the vibration rod is connected with the vibration plate, and a support spring is connected between the vibration plate and a base box assembly. The acceleration sensor base has the advantages that the base can solve the technical problems of the checking and correction of properties and technical indexes of the sensor when the site calibration and checking of the sensor cannot be implemented and a laboratory and site environments are not consistent, and the like; the base is integrally connected with the checking and calibrating mechanism, so under the condition of increase of limited space, the common-state and systematic checking and calibration can be realized, the working efficiency and testing accuracy of the detection system are improved, and the checking and calibration cost is reduced.
