[0067] Fifth, the sliding frame 52 drives the power chuck 53 and the servo electric cylinder 54 to move downward until the retraction hole 53a of the power chuck 53 is coaxially sleeved on the outer periphery of the retaining spring 80, and the output end of the servo electric cylinder 54 pulls the power chuck 53 upward, so that the multiple claws 531 of the power chuck 53 are radially retracted and press the retaining spring 80. When the tension and displacement of the servo electric cylinder 54 reach the preset value, the servo electric cylinder 54 presses the power chuck 53 downward, so that the claws 531 of the power chuck 53 are radially away from the retaining spring 80, and finally the sliding frame 52 drives the power chuck 53 and the servo electric cylinder 54 to lift up;

[0068] The second transport mechanism 40 clamps the screw rod 70 after riveting to the temporary clamp 62 of the detection mechanism 60 through the shift clamp unit 45, and then the detection camera 63 takes a photo, and then the screw rod 70 is rotated 90° and then taken again. After calculating the rivet point depth and the warping height, the riveting work is completed.
