[0068] The synchronizing member 747 comprises a guide shaft 7471, a synchronizing block 7472 and a pushing support rod 7473, the detection support 1 is provided with a limiting groove, the synchronizing block 7472 is in sliding connection at the limiting groove, one end of the guide shaft 7471 is fixedly connected with the synchronizing block 7472, and the other end of the guide shaft 7471 is in sliding connection with the lifting groove 7461, one end of the pushing support rod 7473 is in rotating connection with the synchronizing block 7472, and the other end of the pushing support rod 7473 is in rotating connection with the pushing plate 75 through a hinge support;

[0069] Specific implementation process: when the plurality of clamping plates 81 clamp and fix the mechanical parts, the pushing cylinder 741 operates, so that the linkage frame 742 drives the pushing rack 743 to move towards the rotating gear 744, until the lifting frame 72 vertically moves up, at the same time, the pushing rack 743 is in contact with the rotating gear 744, and with the continuous movement of the pushing rack 743, the rotating gear 744 is synchronously rotated relative to the detection support 1 through the damping rotating shaft 7451, and with the rotation of the damping rotating shaft 7451, the second bevel gear 7453 is driven to rotate through the first bevel gear 7452, and the second bevel gear 7453 drives the lifting sleeve 746 to rotate through the synchronizing shaft 7454;

[0070] When the rotating sleeve rotates, the lifting groove 7461 on the rotating sleeve rotates synchronously relative to the guide shaft 7471, and the guide shaft 7471 is vertically upwardly moved along the limiting groove together with the synchronous block 7472 under the limiting action of the limiting groove and the synchronous block 7472. When the synchronous block 7472 is vertically upwardly moved, the pushing plate 75 is pushed by the pushing rod 7473, and the second industrial camera 76 is moved toward the lower side of the mechanical part under the limiting action of the sliding hole of the pushing plate 75.

[0071] Until the lifting frame 72 stops upward movement, the second industrial camera 76 moves to the lower side of the mechanical part, and the mechanical part is detected.

[0072] When the mechanical part is detected, the plurality of clamping plates 81 place the mechanical part on the rotating disc 52, the pushing cylinder 741 is operated to deviate the pushing rack 743 from the vertical direction of the rotating gear 744, so that when the lifting frame 72 is upwardly moved again, the pushing plate 75 does not move toward the mechanical part. At this time, the detected mechanical part can be separated from the detection support 1 with the operation of the conveying mechanism 3.

The lifting frame 72 is fixedly connected with the lifting block 713.

[0075] Further, when the position of the lifting frame 72 relative to the detection support 1 is adjusted, the lifting motor 712 is operated to further rotate the lifting screw 711 relative to the inside of the moving groove. When the lifting screw 711 rotates, the lifting block 713 is driven, so that the lifting block 713 drives the lifting frame 72 to move upwardly or downwardly relative to the detection support 1 under the limiting action of the moving groove.
