[0036] 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:

[0037] like Figure 3 and Figure 7As shown, place the rod to be welded between each pair of jaws 47, place the connecting joint inside the corresponding rotating cylinder 14, and adsorb it on the magnet block 31. The magnet block 31 plays a role of pre-fixing. After welding is completed, the magnetic suction force of the magnet block 31 is not sufficient to move the load-bearing rod as a whole, and it will automatically detach. Start the motor 10 to work through the controller. As Figure 1 、 Figure 2 and Figure 5 shown, make the motor 10 drive the first turntable 18 and the second turntable 20 to rotate synchronously. At this time, the second turntable 20 drives the fifth gear 40 and the contact rod two 41 thereon to rotate through the second arc-shaped rack 39, so that the fifth gear 40 drives the corresponding roller 43 to rotate through the pulley assembly 17, thereby making the roller 43 drive the conveyor belt 4 to run, and further making the conveyor belt 4 drive the first clamping assembly 6 and the second clamping assembly 7 thereon to run synchronously. During this process, the first arc-shaped rack 38 does not contact the first gear 12, and the cylinder 9 is in a contracted state. The third gear 15 does not contact the second gear 13. When the fifth gear 40 rotates one circle, the contact rod two 41 contacts the second touch switch 42, and at this time the second arc-shaped rack 39 just disengages from the fifth gear 40 and does not contact, so that the fifth gear 40 stops driving the conveyor belt 4 to run. As Figure 4 shown, and at this time the second pin rod 54 slides from the straight groove 44 to the middle of the V-shaped groove 45. During this process, the second pin rod 54 drives the slide rod 50 to move downward, and applies a downward pressure to the two toggle levers 48 through the first pin rod 53, so that the toggle levers 48 drive the jaws 47 to clamp the rod.

[0038] As described above, the touch switch two 42 transmits the touch signal of the touch rod two 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 seat 25 to compress the first spring 24, so that the first spring 24 obtains a restoring force. At the same time, while the slide seat 25 moves on the slide rail 21, it drives the rotating cylinder 14 and the third gear 15 to move synchronously through the second shaft bracket 28, and under the action of the twist rod 27, the sixth gear 55 drives the first gear ring 35 to rotate, so that the first gear ring 35 drives each fourth gear 37 to rotate through the second gear ring 36. Furthermore, the fourth gear 37 drives the clamping plate 32 to approach the connection joint through the screw rod 33 and clamps the connection joint. At the same time, it automatically aligns the connection joint, so that the connection joint is coaxial with the end of the rod body and is in tight contact. When the slide seat 25 contacts the touch switch three 30, the twist rod 27 just does not contact the sixth gear 55. The touch switch three 30 transmits the touch signal of the slide seat 25 to the controller, and the controller controls the cylinder 9 to hold and starts the welder 16 to work. At this time, the third gear 15 just meshes with the second gear 13, and at the same time, the first arc-shaped rack 38 meshes with the first gear 12, so that the first turntable 18 drives the first gear 12 to rotate through the first arc-shaped rack 38. Thus, the first gear 12 drives the second gear 13 to rotate synchronously through the shaft rod 11, so that the second gear 13 drives the rotating cylinder 14 to rotate through the third gear 15. Furthermore, the rotating cylinder 14 drives the connection joint and the rod body to rotate synchronously, so that the welder 16 can weld the connection part in a circular path.

[0039] As described above, while the second gear 13 rotates, it drives the first contact rod 29 to rotate. When the first contact rod 29 rotates one circle and makes contact with the first touch switch 23, at this time, the rotating cylinder 14 drives the connecting joint and the rod body to rotate one circle to complete welding. At the same time, the first arc-shaped rack 38 just disengages from the first gear 12 and is not in contact. At this time, the first touch switch 23 transmits the touch signal of the first 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 restoring force of the first spring 24, the sliding seat 25 slides reversely and resets, so that the sliding seat 25 drives the rotating cylinder 14 and the third gear 15 to reset through the second shaft bracket 28, so that the third gear 15 disengages from the second gear 13 and is not in contact. And under the action of the twist rod 27, the sixth gear 55 drives the first toothed ring 35 to rotate reversely, so that the first toothed ring 35 drives each fourth gear 37 to rotate reversely through the second toothed ring 36. Thus, the fourth gear 37 drives the clamp 32 to loosen the connecting joint and reset through the screw rod 33. At this time, the second arc-shaped rack 39 meshes with the fifth gear 40 again, so that the fifth gear 40 drives the corresponding roller 43 to rotate through the belt pulley assembly 17, so that the roller 43 drives the conveyor belt 4 to run, and outputs the load-bearing rod corresponding to the V-shaped groove 45 that has been processed, and at the same time transfers each component of the next load-bearing rod to be welded to the V-shaped groove 45. During the process of the second pin rod 54 moving from the V-shaped groove 45 to the straight groove 44, the second pin rod 54 drives the slide bar 50 to move upward, and the slide bar 50 applies a thrust to the two toggle levers 48 through the first pin rod 53, so that the toggle levers 48 drive the jaws 47 to open, so as to remove the welded load-bearing rod. In this way, it only needs to place the connecting joint and the rod body on the corresponding first clamping assembly 6 and the second clamping assembly 7 in front of the welding station, and then realize automatic centering clamping of the connecting joints at both ends of the rod body and synchronous rotary welding, thus greatly improving work efficiency. Just remove the welded load-bearing rod at the back of the welding station, and the operation is simple and convenient.
