When detecting, the body is pressed from both sides to the detection station by the manipulator, and the manipulator vertically upwards leaves, and the body is fixed to the three-jaw (holding) chuck, connects 6 outside mechanical control unit lateral shifting body supersound flexible probe detection device of protruding structure, is close to the body, and body rotation a week accomplishes detection achievement, and body supersound flexible probe detection device transversely leaves and is detected work, and the three-jaw (holding) chuck is loosened, and the manipulator vertically downwards and centre gripping body leaves the detection station, accomplishes a detection achievement. The above-mentioned manipulator, three-jaw chuck, external mechanical control unit are prior art and are only used for describing the working mode of the present invention in the embodiment.

As shown in fig. 1, the detection bracket includes at least two probe fixing grooves 4, a protrusion structure 6, a water inlet 21, a water outlet 22, and a flexible probe 3. The flexible probe 3 is an ultrasonic liquid immersion type phased array probe, the phased array probe needs to be partially or completely immersed into liquid when the liquid immersion type phased array probe is used, and the probe is often used for the situation that a rigid wedge block cannot be well matched with the surface of a detected workpiece. Therefore, in the detection process of the projectile body, a water layer is arranged between the projectile body and the flexible probe 3 to be detected, the ultrasonic energy is effectively coupled into the projectile body to be detected by utilizing the local water immersion technology, the flexible probe 3 can be protected from being damaged by contacting the projectile body, the incidence of the acoustic beam energy in the axial direction of the inclined axis can be further realized, and the annular crack defect can be further detected.

The flexible probe 3 is selected for use so as to better adapt to the shape curved surface of the projectile body, so that the flexible ultrasonic probe can be tightly attached to the surface of the detected body, the energy loss of ultrasonic waves is reduced, the ultrasonic waves can be transmitted and/or received more accurately, and the detection precision is improved. The acoustic matching layer of the flexible probe 3 is placed in front of the probe and the damping layer for absorbing unwanted vibrations is placed on the back of the probe. The flexible probe 3 sends out ultrasonic waves, and the ultrasonic waves are received by the flexible probe 3 with a receiving device.

Because the surface plane of the projectile body is composed of straight lines and curved lines, the flexible probe 3 is adopted, so that the probe and the surface of the projectile body can be combined more tightly, the acquired data is more accurate, and the imaging effect is better.

A probe fixing groove 4 for mounting the flexible probe 3 is formed in the detection support 5, and the size, shape and dimension of the probe fixing groove 4 are matched with those of the flexible probe 3; the flexible probe 3 is fixed in the probe fixing groove 4. The number of the probe fixing grooves 4 is the same as that of the flexible probes 3, and the number of the flexible probes 3 depends on the size of the projectile body, for example: when the body shape of the bomb is large, 3-5 probe fixing grooves 4 can be designed for mounting a plurality of flexible probes 3.
