The detection device based on the integrated reed is characterized in that: and (3) making notches on two adjacent surfaces of each probe frame respectively, drilling the notches to tap, and screwing down the screws to enable the probe frames to clamp the probes by utilizing the small elastic deformation of the rigid structure after the probes are placed in the notches.
The detection device based on the integrated reed is characterized in that: the probe frame, the integrated reed and the pressing plate are designed to have corresponding inner diameters and radians according to different curved surfaces.
Compared with the prior art, the invention has the beneficial effects that:
1. the invention provides a curved surface detection device with few parts, a main body only comprises four parts, namely a pressing plate, an integrated reed, a probe frame and a probe assembly, and the curved surface detection device has the advantages of compact structure, strong reliability, longer service life and light weight, and the probe can perfectly fit a curved surface.
2. The integrated reed clamped in the middle of the invention can not yield under the condition of meeting a certain stress, and the stress of the probe can be finally transmitted to the integrated reed when the probe is moved and scanned, so that the integrated reed elastically deforms and the probe is kept to be always attached to a curved surface.
3. Because the probe frame and the probe are rigid parts, the complete attachment of the probe frame and the probe is difficult, in the probe frame, two notches are formed in two adjacent surfaces of the probe frame, holes are drilled and tapped simultaneously, after the probe is placed in the probe frame, a screw can be screwed down to clamp the probe frame by utilizing the tiny elastic deformation of a rigid structure, the structure is compact, the reliability is high, and the service life is long.
