[0017] S2. Turn on the fourth cylinder.

Moreover, the flaw detection head 44 can move horizontally and vertically, which is convenient for flaw detection at different positions on the crankshaft, thereby improving the flaw detection range.

[0039] A fully automatic crankshaft detection method specifically comprises the following steps:

[0040] S1. Place the crankshaft on the bracket 29 and move the crankshaft to the second clamping plate 552 through the transmission of the third servo motor 21 and the threaded rod 22;

[0041] S2. Turn on the fourth cylinder 522. The extension of the fourth cylinder 522 drives the first rack 53, the gear 54, and the second rack 55 to move relative to each other, thereby clamping the crankshaft.

[0042] S3, controlling the extension and contraction of the second cylinder 41 and the third cylinder 43 to facilitate adjustment of the flaw detection head 44 to different areas on the crankshaft for flaw detection;

[0043] S4. The crankshaft after the flaw detection is moved backward by the transmission function of the third servo motor 21 and the threaded rod 22. When the crankshaft moves between the two positioning plates 981, the outer diameter thereof is detected.

[0044] Working principle: When using this device, the crankshaft is placed on the bracket 29, and the crankshaft is moved to the second clamping plate 552 through the transmission of the third servo motor 21 and the threaded rod 22. Then the first cylinder 25 is controlled to shorten, and the crankshaft is separated from the bracket 29. Then the fourth cylinder 522 is controlled to extend. The extension of the fourth cylinder 522 can drive the first rack 53, the gear 54 and the second rack 55 to transmit, thereby driving the first clamping plate 531 and the second clamping plate 552 to move relative to each other, completing the clamping of the crankshaft. Then the second cylinder 41 and The third cylinder 43 is extended and retracted, and the second cylinder 41 can drive the flaw detection head 44 to move left and right after being extended and retracted. The third cylinder 43 can drive the flaw detection head 44 to move up and down after being extended and retracted. When the flaw detection head 44 contacts the crankshaft, flaw detection can be performed on different areas of the crankshaft. After the flaw detection is completed, the fourth cylinder 522 is controlled to be shortened. At this time, the first clamping plate 531 is separated from the crankshaft, and then the first cylinder 25 is controlled to be extended until the bracket 29 contacts the crankshaft and lifts the crankshaft. At this time, the transmission effect of the third servo motor 21 and the threaded rod 22 is used to lift the flaw detection-tested part. The crankshaft moves backward. When the crankshaft moves between the two positioning plates 981, the first cylinder 25 is controlled to shorten. At this time, the bracket 29 is separated from the crankshaft. Then the second servo motor 954 is controlled to rotate forward and reverse. The forward and reverse rotation of the second servo motor 954 can drive the first guide frame 951 and the second guide frame 961 to move left and right, thereby driving the two positioning plates 981 to move left and right. Then the first servo motor 91 is controlled to rotate forward. At this time, the first bracket 911 and the second bracket 912 can be driven to rotate forward, thereby driving the third bracket 92 and the fourth bracket 93 to move. Through the movement of the third bracket 92 and the fourth bracket 93, the first fixed block 921 and the second fixed block 931 can be driven to move relative to each other, thereby driving the first metal plate 95 and the second metal plate 96 to move relative to each other. After the first metal plate 95 and the second metal plate 96 move relative to each other, the two positioning plates 981 can be driven to move relative to each other. When the two positioning plates 981 contact the surface of the crankshaft, the limit block 94 stops moving at this time. Then, the outer diameter of the crankshaft can be detected by observing the scale lines 7 on the third support plate 14 and the fourth support plate 15.
