[0029] A linkage mechanism is arranged between the installation block 5 and the arc-shaped pushing plate 7, and a limiting mechanism is arranged between both sides of the rotating support 3 and the bottom of the workbench 1.

[0030] ​When the pre-detection piece needs to be detected by the ultrasonic detector 4, the pre-detection piece is placed in the plane under the workbench 1, the air cylinder 6 is pushed to start the arc-shaped push plate 7 to move through the linkage mechanism, the arc-shaped push plate 7 contacts and pushes the pre-detection piece to the center position of detection, the rubber soft pad on the arc-shaped push plate 7 contacts the pre-detection piece, and when the pre-detection piece reaches the center position of detection, the two ends of the arc-shaped push plate 7 contact and fit to surround the pre-detection piece, the rubber soft pads on the two arc-shaped push plates 7 protect the pre-detection piece from being extruded, at a certain time point in the process, the limiting mechanism disconnects the fixation of the rotating support 3, the reduction motor 2 works to drive the rotating support 3 to start rotating, and the two ultrasonic detectors 4 detect the surface of the pre-detection piece by ultrasonic scanning. In the process of rotating the rotating support 3 driven by the reduction motor 2, the rubber soft pads on the two arc-shaped push plates 7 contact the pre-detection piece to provide friction for it, so that the two arc-shaped push plates 7 remain stationary, and only the rotating support 3 rotates. When the rotating support 3 rotates one circle, the limiting mechanism fixes the rotating support 3 again, and the air cylinder 6 is pushed to bring the arc-shaped push plate 7 back through the linkage mechanism, and then the pre-detection piece can be taken down and replaced with a new one for detection.

[0032] When the pre-detection piece needs to be detected, the air cylinder 6 is pushed to drive the moving block 13 to move in the moving groove 12, the extension rod 14 is extended out of the moving groove 12, the movement of the extension rod 14 drives the sliding block 11 to move, and the arc-shaped push plate 7 moves accordingly. When the arc-shaped push plate 7 pushes the pre-detection piece, it will be offset, when the two arc-shaped push plates 7 contact, the gradually contacting of the two arc-shaped push plates 7 makes the offset arc-shaped push plate 7 push back to its original position, at this time, the stabilizing blocks 8 gradually insert into the stabilizing grooves 9, the stabilizing blocks 8 and the stabilizing grooves 9 make the two arc-shaped push plates 7 connected as a whole, and the two arc-shaped push plates 7 form a complete ring. When the rotating support 3 rotates, the rubber soft pads on the two arc-shaped push plates 7 contact the pre-detection piece to provide friction for it, the sliding block 11 can normally move in the sliding groove 10, and the sliding block 11 is driven by the rotating support 3 to pass through another sliding groove 10 and return to the original sliding groove 10.

[0035] When the pushing cylinder 6 starts to push the moving block 13 to move, the pushing block 21 moves along, and the pushing block 21 pushes the bottom of the auxiliary rod 17 during the movement, the auxiliary rod 17 rotates around the fixed block 18 corresponding to the auxiliary rod 17, the restoring soft block 23 on both sides of the auxiliary rod 17 is deformed by extrusion, the top of the auxiliary rod 17 moves through the connecting rope 19 to drive the bottom of the locking rod 16 to move, so that the locking rod 16 rotates around the fixed block 18 corresponding to the locking rod 16, and since one side of the locking groove 20 is provided with a slope, the top of the locking rod 16 is gradually inclined and leaves the locking groove 20, the arc-shaped soft block 24 is deformed by being pulled, and the rotating support 3 is driven by the speed reducer 2 to rotate because the locking of the limiting mechanism is lost, during the rotation of the rotating support 3, the top of the locking rod 16 is limited by the bottom surface of the workbench 1 and keeps in close contact with the bottom surface of the workbench 1, when the locking rod 16 completely leaves the locking groove 20, the moving block 13 will continue to move for a distance, and the pushing block 21 is separated from the pushing of the auxiliary rod 17, the restoring soft block 23 resets to push the auxiliary rod 17 back to the original position, and the connecting rope 19 is in a relaxed state, because the two limiting mechanisms are asymmetrically arranged, the positions of the two locking grooves 20 are different, after the rotating support 3 is driven by the speed reducer 2 to rotate for one circle, the locking rod 16 returns to the position of the locking groove 20, the arc-shaped soft block 24 resets to push the locking rod 16 back into the locking groove 20, the connecting rope 19 returns to the tight state, and waits for the next pushing of the moving block 13, during the process that the pushing cylinder 6 drives the moving block 13 to return to the original position, because one side of the top of the pushing block 21 is provided with a slope, the auxiliary rod 17 pushes the pushing block 21 to shrink into the moving block 13, and the spring 22 is compressed, after the moving block 13 leaves the auxiliary rod 17, the spring 22 pushes the pushing block 21 to return to the original position.
