[0061] Description of the processing of the present invention:

[0062] During processing, first place the long pipe on the rollers 402 of the multiple pipe cutting and grooving mechanisms 4, then start the drive motor 403 to drive the two rollers 402 to rotate through gear transmission, and then the feed drive cylinder 404 drives the tool holder 405 to feed vertically, thereby realizing the feeding movement of the pipe cutting and grooving tool 406, and the cutter 4061 of the pipe cutting and grooving tool 406 first contacts the pipe 11 for cutting processing (after contact, the pipe cutting and grooving tool 406 is also rotated by force), when the cutter 4601 cuts the pipe 11 and continues to feed vertically, and then the grooving knife 4603 contacts the pipe 11 for grooving (the grooving depth is controlled by controlling the feed amount), and the feed drive cylinder 404 is reset after the grooving is completed. The unloading cylinder 601 starts to drive the unloading driving plate 602 to rotate. The arc-shaped groove 603 on the unloading driving plate 602 picks up the cut pipe 11 and guides the pipe 11 to the guide rack 604. Under the action of gravity, the pipe 11 rolls into one side of the nut fastening mechanism 5; one interface of the connector 16 is sleeved on the positioning column 5022, and the interface to be connected with the nut 15 is aligned with the wrench opening 5036 on the sprocket wheel 5035, and then the cylinder 5024 is pressed. The joint 16 is compressed by the compression block 5025 at the start; then the nut 15 is manually inserted into the pipe 11, and the retaining spring 14 is installed in the slot 13. The retaining spring 14 limits the nut 15, and then the pipe 11 with the nut 15 and the retaining spring 14 is set on the supporting roller 506, and the nut 15 is inserted into the wrench opening 5036, and then the nut 15 is aligned with the interface of the joint 16 and inserted by moving the moving seat 5032 (the insertion here is very small, just aligned and inserted), and then the motor 5038 is started, and the motor 5038 drives the sprocket wheel 5035 to rotate through the chain drive, and the rotation of the sprocket wheel 5035 drives the nut 15 on the wrench opening 5036 to rotate and screw it into the interface of the joint 16. During the screwing-in process, the nut 15 follows in the wrench opening 5036 (it can move along the feed direction, and the length of the wrench opening 5036 is greater than the length of the nut 15). The moving seat 5032 can also set the movement variable.
