[0024] In this utility model, the conveying mechanism 2 includes: a rotating frame 21, one end of which is equipped with a rotating mounting plate 22 and the other end with a rotating shaft 23. The rotating mounting plate 22 is connected to the slewing bearing 15, and the rotating shaft 23 is mounted on the positioner tail frame 12 via a bearing seat 17. The conveying rollers 24 are installed parallel and evenly on the rotating frame 21, and the top surface of the conveying rollers 24 forms a conveying surface, which is at the same horizontal height as the conveying rollers 16 installed on the positioner tail frame 12.

[0025] A drive mechanism 13 is mounted on the head frame 11 of the positioner. A drive gear 14 is mounted on the output shaft of the drive mechanism 13. A slewing bearing 15 is connected to the end of the conveying mechanism 2. The slewing bearing 15 meshes with the drive gear 14. The drive mechanism 13 drives the gear 14 to drive the slewing bearing 15, thereby driving the conveying mechanism 2 to rotate. The drive mechanism 13 and the slewing bearing 15 are connected by the gear 14 mounted on the drive mechanism 13. The drive mechanism 13 drives the gear 14, which in turn drives the conveying mechanism 2 to rotate via the slewing bearing 15. Two sets of conveying rollers 16 and bearing seats 17 are mounted on the tail frame 12 of the positioner. The top surfaces of the two sets of conveying rollers 16 form a gantry conveying surface, and the top surfaces of the multiple sets of conveying rollers 24 also form a gantry conveying surface. The conveying surfaces of the conveying rollers 24 and the conveying surfaces of the conveying rollers 16 are at the same horizontal level, and the gantry can be conveyed via the conveying rollers 16 and 24.

[0026] A rotating frame 21 is installed between the positioner head frame 11 and the positioner tail frame 12 via a rotating mounting plate 22 and a rotating shaft 23. The rotating frame 21 is installed with the positioner head frame 11 via the rotating mounting plate 22.

Simultaneously, the cylinder 332 retracts, and the clamping block 333 moves to a position that does not interfere with the gantry conveying. The gantry passes the conveying surface and enters above the gantry clamping device 3. Different gantry clamping devices 3 are used to clamp the gantry depending on its length. During clamping, the cylinder 332 extends, and the clamping block 333 clamps the gantry at an angle. After clamping, the drive mechanism 13 drives the gear 14, which in turn drives the conveying clamping device 2 to rotate and reposition for welding via the slewing bearing 15. After welding is completed, the cylinder 332 retracts, the clamping block 333 moves to a position that does not interfere with the gantry loading and unloading, and the gantry is hoisted to the next workstation.
