The invention relates to the technical field of ultrasonic detection, in particular to a compression force feedback closed-loop control mechanism which comprises a baffle, a sliding mechanism and a detection box. An adjuster is arranged at the top of the sliding mechanism, a motor is fixedly installed on the front face of the adjuster, and the output end of the motor is connected with a threaded rod. A fixing plate is connected to the middle of the outer surface of the threaded rod, a connecting plate is connected to the bottom of the threaded rod, and a sliding block is fixedly connected to the back of the connecting plate. According to the compression force feedback closed-loop control mechanism, a pressure feedback closed-loop system is formed through a first pressure sensor, a second pressure sensor and a displayer, an electric telescopic device and the motor are matched to form the pressure feedback closed-loop control system, during ultrasonic detection, experience and operation of doctors cannot be excessively relied on, and during subsequent detection, whether the position of a detection box is accurate or not can be judged only through numerical values of the first pressure sensor and the second pressure sensor, and the situation that scanning results are inaccurate due to insufficient experience of doctors is avoided.
Description
technical field [0001] The invention relates to the technical field of ultrasonic detection, in particular to a compression force feedback closed-loop control mechanism. Background technique [0002] Ultrasonic testing refers to a non-destructive testing method that uses ultrasonic waves to inspect internal defects of metal components. Use the transmitting probe to transmit ultrasonic waves to the surface of the component through the coupling agent. When the ultrasonic wave travels inside the component, it will have different reflection signals (echoes) when it encounters different interfaces. Using the time difference between different reflection signals transmitted to the probe, the internal defects of the component can be inspected . [0003] In traditional handheld ultrasound scanning, the doctor holds the scanning device to press and move on the human body for scanning, which greatly depends on the doctor's operation, and it is easy to cause inconsistency or missed dia...
