Universal rock-soil sample acoustic wave velocity test control platform

The invention discloses a universal rock and soil sample acoustic wave velocity test control platform. According to the technical scheme, during sound velocity measurement, a to-be-tested sample is placed at the position close to the second end of the optical axis vertical support, and the optical axis vertical support is controlled to linearly slide relative to the bottom plate until the sound wave probe located at the second end makes contact with the surface of the to-be-tested sample. The force sensor connected with the optical axis vertical support can collect a pressure value in the process of linearly sliding along with the optical axis vertical support, and reflects the distance of the optical axis vertical support relative to the fixed support bracket at the force sensor end through the pressure value, thereby finally measuring the contact tightness of the sonic probe on the surface of a sample to be tested. And finally, the position of the optical axis vertical support is adjusted until the sonic pr
