The turntable 1 is a disc-shaped structure, and the upper end surfaces of the turntables 1 are on the same horizontal plane and the rotation centers (centers of the discs) are distributed on the same straight line. When multiple water tanks 2 are used, the volume and size of the water tanks 2 can be different, but the turntables 1 located in the water tanks 2 must be exactly the same. Each water tank 2 is equipped with a set of motion axes, and an immersion ultrasonic probe 3 is installed on the motion axis of the water tank 2. The motion axis of the water tank 2 and the rotation axis of the turntable 1 are controlled by a motion axis controller 23. A video camera 5 is installed above the water tank 2, and the image captured by the video camera 5 is displayed on a display screen 6. A door-shaped hanging frame 4 is also provided above the water tank 2, and a guide rail 7 is installed on the hanging frame 4. The center line of the guide rail 7 passes through the center of each turntable 1 (that is, the vertical projection of the guide rail 7 on the horizontal plane where the end surface of the turntable is located connects the rotation center of all turntables 1). A lifting shaft 9 is also installed on the hanging frame 4, and a claw plate 10 is installed at the bottom of the lifting shaft 9. The lifting shaft 9 is driven by a motor group 8 and can move on the guide rail 7 and can also rise, fall or rotate relative to the water tank 2. The motor group 8 includes multiple motors, which respectively control the translation, rise, fall or rotation of the lifting shaft 9. The motor group 8 is controlled by a hanging controller 31.

The tracks 18 are arranged on one side or both sides of the column (row) where the water tank 2 is located. The tracks 18 are used to position and move the parts cart 19. The track 18 is also provided with a limit block 30 for positioning the movement position of the parts cart 19. The parts cart 19 is used to load and transport parts 15. A three-claw turntable base 17 is fixedly installed on the parts cart 19. The three-claw turntable base 17 has the same size as the turntable 1. A three-claw turntable 16 is detachably installed on the three-claw turntable base 17. The three-claw turntable 16 is used to clamp the parts 15.

It can move back and forth along the radial direction of the three-claw turntable 16, so as to achieve the clamping and loosening of the part 15. The hook is clamped on the screw guard plate 14 to lift the three-claw turntable 16 (the screw guard plate 14 is a structure similar to channel steel, so the screw guard plate 14 has a certain strength and can bear the weight of the supporting part 15 and the three-claw turntable 16). The lower part of the three-claw turntable 16 has a conical groove 25 and three positioning balls 24, corresponding to the conical boss 26 and V-shaped groove 27 on the turntable 1 (such as Figure 4 The cross section of the V-shaped groove 27 is V-shaped, including two intersecting inclined surfaces), and one of the three V-shaped grooves 27 is rotated 90 degrees from the other two (such as Figure 5 , one V-shaped groove 27 at the left end is in a horizontal state, and the two V-shaped grooves 27 at the right end are in a vertical state, that is, the V-shaped groove 27 at the left end is rotated 90 degrees to obtain the state of the V-shaped groove 27 at the right end), and the conical boss 26 and V-shaped groove 27 on the turntable 1 are consistent in size with the conical boss 26 and V-shaped groove 27 on the three-claw turntable base 17 on the parts car 19. The turntable 1 and the three-claw turntable 16, and the three-claw turntable base 17 and the three-claw turntable 16 are positioned and aligned by matching the conical boss 26 with the conical groove 25, and matching the spherical surface of the positioning ball 24 with the inclined surface of the V-shaped groove 27. During flaw detection, the part 15 is first clamped on the three-claw turntable 16 of the part cart 19 through the pressure plate at the end of the screw in the screw guard plate 14, and then the part cart 19 is pushed onto the track 18 until the limit block 30, and then the lifting shaft 9 is lowered to the appropriate position, the claw plate 10 is rotated (the hook is installed in place and connected to the screw guard plate 14), and then lifted to an appropriate height, and then moved to the top of the turntable 1 in the corresponding water tank 2, and then lowered to an appropriate position to complete the natural centering and positioning of the three-claw turntable 16 and the turntable 1, and then the claw plate 10 is rotated in the opposite direction (unhooked), lifted, and returned to the starting position, that is, the loading process of the part 15 is completed, conversely, the part 15 is transferred from the turntable 1 to the part cart 19, and the unloading process of the part 15 is completed. The loading and unloading process of the part 15 can be controlled by program.
