The clamping claw of the manipulator body 54 opens to release the D-tube 100, and the D-tube moving assembly 25 further processes or transports the D-tube 100.

[0048] The clamping device 6 includes a second support frame 61, a sixth moving mechanism 62, a pipe clamping assembly 63 and a seventh moving mechanism 64. The seventh moving mechanism 64 is arranged on the second support frame 61. The second support frame 61 is used for moving the sixth moving mechanism 62. The sixth moving mechanism 62 enables the pipe clamping assembly 63 to move left and right, and the pipe clamping assembly 63 also has the function of moving up and down, and a plurality of fixed heads are distributed on the pipe clamping assembly 63.

[0049] In this embodiment, the seventh moving mechanism 64 drives the sixth moving mechanism 62 (and the pipe clamping assembly 63) to move to the target position in the front-to-back direction according to a preset program or instruction. The sixth moving mechanism 62 then drives the pipe clamping assembly 63 to perform fine adjustment in the left-right direction as needed to ensure that the fixed head can accurately align with the pipe. Then, the lifting mechanism in the sixth moving mechanism 62 is started to push the pipe clamping assembly 63 downward so that the fixed head contacts the pipe. The driving component (such as a cylinder, a hydraulic cylinder or an electric push rod) works to push the fixed head to apply a predetermined clamping force to the pipe. During the clamping process, the sixth moving mechanism 62 and the seventh moving mechanism 64 can adjust the position and posture of the pipe clamping assembly 63 as needed to ensure the uniformity and stability of the clamping effect. When the clamping operation is completed, the driving component stops working, and the pipe clamping assembly 63 rises and returns to the initial position under the drive of the lifting mechanism.
