[0025] Working principle and advantages of the present invention: When the double-end synchronous welding device for processing aircraft load-bearing rods is used, the working process is as follows: like Figure 3 and Figure 7As shown, the rod to be welded is placed between each set of clamping jaws 47, and the connecting joint is placed in the corresponding rotating drum 14 and adsorbed on the magnetic block 31. The magnetic block 31 plays a role of pre-fixation. After the welding is completed, the magnetic attraction of the magnetic block 31 is not enough to attract the bearing rod as a whole and it will automatically detach. The motor 10 is started by the controller to work, as shown in FIG. Figure 1 , Figure 2 and Figure 5 As shown, the motor 10 drives the turntable 1 18 and the turntable 2 20 to rotate synchronously. At this time, the turntable 2 20 drives the gear 5 40 and the touch rod 2 41 thereon to rotate through the arc rack 2 39, so that the gear 5 40 drives the corresponding roller 43 to rotate through the pulley assembly 17, so that the roller 43 drives the conveyor belt 4 to run, and then the conveyor belt 4 drives the clamping assembly 1 6 and the clamping assembly 2 7 thereon to run synchronously. In this process, the arc rack 1 38 does not contact the gear 1 12, the cylinder 9 is in a contracted state, and the gear 3 15 does not contact the gear 2 13. When the gear 5 40 rotates one circle, the touch rod 2 41 contacts the touch switch 2 42, and at this time the arc rack 2 39 just disengages from the gear 5 40, so that the gear 5 40 stops driving the conveyor belt 4 to run, as shown in FIG. Figure 4 As shown, at this time, the pin rod 2 54 slides from the straight groove 44 to the middle of the V-shaped groove 45. During this process, the pin rod 2 54 drives the slide rod 50 to move downward, and applies downward pressure to the two levers 48 through the pin rod 1 53, so that the lever 48 drives the clamping claw 47 to clamp the rod body.

[0026] As described above, the touch switch 2 42 transmits the touch signal of the touch rod 2 41 to the controller, and the controller controls the cylinder 9 to work, so that the cylinder 9 extends the piston rod and pushes the slide 25 to compress the spring 1 24, so that the spring 1 24 obtains a restoring force, and the slide 25 moves on the slide rail 21 while driving the rotating drum 14 and the gear 3 15 to move synchronously through the shaft frame 2 28, and under the action of the twisted rod 27, the gear 6 55 drives the ring gear 1 35 to rotate, so that the ring gear 1 35 drives each gear 4 37 to rotate through the ring gear 2 36, and then the gear 4 37 drives the clamping plate 32 to approach the connecting joint through the screw 33, and clamps the connecting joint, and automatically aligns the connecting joint, so that the connecting joint is coaxial with the end of the rod body and abuts against it. Tight contact, when the slide 25 and the touch switch three 30 are in contact, the twisted rod 27 just does not contact the gear six 55, and the touch switch three 30 transmits the touch signal of the slide 25 to the controller. The controller controls the cylinder 9 to maintain and starts the welding machine 16. At this time, the gear three 15 is just engaged with the gear two 13, and the arc rack one 38 is engaged with the gear one 12, so that the turntable one 18 drives the gear one 12 to rotate through the arc rack one 38, so that the gear one 12 drives the gear two 13 to rotate synchronously through the shaft 11, so that the gear two 13 drives the rotating drum 14 to rotate through the gear three 15, and then the rotating drum 14 drives the connecting joint and the rod body to rotate synchronously, so that the welding machine 16 can weld the connection in a circular path.

[0027] As described above, when gear 2 13 rotates, it drives the contact rod 1 29 to rotate. When the contact rod 1 29 rotates one circle and contacts with the touch switch 1 23, the rotating drum 14 drives the connecting joint and the rod body to rotate one circle to complete the welding. At the same time, the arc rack 1 38 just disengages from the gear 12 and does not contact it. At this time, the touch switch 1 23 transmits the touch signal of the contact rod 29 to the controller. The controller controls the welding machine to stop working and controls the cylinder 9 to retract the piston rod. At this time, under the action of the restoring force of the spring 1 24, the slide 25 slides in the opposite direction and resets, so that the slide 25 drives the rotating drum 14 and the gear 3 15 to reset through the shaft frame 2 28, so that the gear 3 15 is disengaged from the gear 2 13 and does not contact it. Under the action of the twisted rod 27, the gear 6 55 drives the gear ring 1 35 to reverse, so that the gear ring 1 35 drives each gear 4 37 to reverse through the gear ring 2 36, so that the gear 4 37 drives the clamping plate 32 to loosen the connecting joint and reset through the screw 33. The second bar 39 is meshed and connected with the gear five 40 again, so that the gear five 40 drives the corresponding roller 43 to rotate through the pulley assembly 17, so that the roller 43 drives the conveyor belt 4 to run, and outputs the corresponding processed bearing rod at the V-shaped groove 45, and at the same time transfers the various components of the next bearing rod to be welded to the V-shaped groove 45. In the process of the pin rod 2 54 moving from the V-shaped groove 45 to the straight groove 44, the pin rod 2 54 drives the slide bar 50 to move upward, and makes the slide bar 50 apply a thrust to the two levers 48 through the pin rod 1 53, so that the lever 48 drives the clamping claw 47 to open, so as to remove the welded bearing rod, and so on. It is only necessary to place the connecting joint and the rod body on the corresponding clamping assembly 1 6 and clamping assembly 2 7 at the front side of the welding station, and then realize the automatic centering clamping of the connecting joints at both ends of the rod body, and synchronous rotation welding, thereby greatly improving the work efficiency, and the welded bearing rod can be removed at the rear side of the welding station, which is simple and convenient to operate.

[0028] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention.
