Embodiment Construction
[0040] like Figure 1-5 As shown, a coupling system for contact detection of variable curvature components based on ultrasonic phased array technology is mainly composed of couplant 1, couplant adding component 2, adding control component 3, probe component 4, and probe clamping component 5. The couplant 1 is added to the probe assembly 4 through the couplant adding component 2 for coupling, the adding control component 3 controls, feeds back, and adjusts the couplant adding component 2, and the probe component 4 passes The probe clamping assembly 5 performs clamping.
[0041] The coupling agent 1 used in the embodiment of the present invention is to mix viscous glycerin and pure water in an appropriate proportion, which not only ensures the viscosity of the coupling agent, does not flow quickly at the probe, but also ensures the fluidity of the coupling agent, so that the coupling Agents can be added automatically.
[0042] The couplant adding assembly 2 includes a box body...

Abstract
The invention discloses a coupled system used for contact type detection of a variable curvature component and based on an ultrasonic phased array technology. The coupled system comprises a coupling agent adding component (2), an addition control component (3), a probe component (4) and a probe clamping component (5), wherein the coupling agent adding component (2) adds a coupling agent to the probe component (4) for coupling; the addition control component (3) is used for controlling, feeding back and adjusting the coupling agent adding component (2); and the probe clamping component (5) is used for clamping and controlling the probe component (4). The coupled system has the advantages as follows: the coupled system which is suitable for ultrasonic phased array detection of a variable curvature component detection device under the multi-pose operation environment can be used as a coupled system module for automatic ultrasonic phased array detection and can further be used as an independent auto-coupling manual detection system, the use is convenient, and the coupled system not only can be applied to runner blades of a water turbine, but also can be conveniently applied to components with similar structural characteristics.
Description
technical field [0001] The invention relates to the technical field of ultrasonic phased array detection of variable curvature components, in particular to a coupling system for contact detection of variable curvature components based on ultrasonic phased array technology. Background technique [0002] Ultrasonic testing means that the ultrasonic wave emitted by the ultrasonic probe is transmitted to the component under test through the acoustic coupling medium, and finally the continuity, A non-destructive testing method for integrity and other properties. In industrial testing, ultrasonic testing is widely used due to its advantages of large detection range, high sensitivity, and fast speed. [0003] Ultrasonic contact testing refers to an ultrasonic testing method in which the ultrasonic probe is in contact with the component under test and introduced into the component through the acoustic coupling medium. It is especially widely used in industrial testing. In ultrason...
