[0021] Working principle and advantages of the present invention: When the welding device for the aircraft wing support frame is used, the working process is as follows: like Figure 1 , Figure 3 and Figure 5 As shown, the wing support frame assembly to be welded is placed on the tooling 3, and the controller controls the conveying device 2 to drive the tooling 3 and the wing support frame assembly thereon to approach the cross-connecting plate 9. When the lever 4 corresponding to the tooling 3 contacts the touch switch 1 24 on the inner wall of the arc plate 20, the touch switch 1 24 transmits the contact signal of the lever 4 to the controller, and the controller controls the cylinder 2 14 to work, so that the cylinder 2 14 drives the pressure plate 10 to move downward. When the pressure plate 10 contacts the wing support frame assembly on the tooling 3, the wing support assembly is pressed, and each through hole 11 corresponds to each welding point position, as shown in FIG. Figure 2 As shown, at this time, the slide plate 31 compresses the spring three 32 under the continued push of the cylinder two 14. When the slide plate 31 contacts the touch switch two 33, the touch switch two 33 transmits the contact signal of the slide plate 31 to the controller. The controller controls the cylinder two 14 to stop working. At the same time, the controller controls the cylinder three 28 to work, so that the piston rod of the cylinder three 28 pushes the locking rod 29 to approach the slide bar 27, and the teeth on the locking rod 29 engage with the teeth on the slide bar 27 to achieve locking of the slide bar 27 and the guide sleeve 26, thereby maintaining the clamping stability of the pressure plate 10 on the wing support assembly to avoid misalignment of the components at the welding point position during welding. At the same time, the controller also controls the welding gun 13 to weld the welding point position.

[0022] As described above, the lever 4 is in contact with the arc plate 20 and gives a thrust to the arc plate 20, so that the arc plate 20 drives the cross-connecting plate 9 to move synchronously with the tooling 3 through the slide tube 17 and the suspension rod 18, and then the cross-connecting plate 9 drives the sliding sleeve 7 to slide on the screw rod 6 and compresses the spring 25, so that the spring 25 obtains a restoring force. The reaction force applied by the spring 25 to the sliding sleeve 7 makes the lever 4 stably in contact with the arc plate 20, so that the welding operation can be carried out without stopping the vehicle, thereby improving the welding efficiency of the wing support frame.

[0023] When the wedge surface of the wedge block 15 is in contact with the push rod 16, the reaction of the push rod 16 causes the slide 17 to move upward on the suspension rod 18, thereby separating the arc plate 20 from the lever 4. At this time, the touch switch 1 24 is no longer in contact with the lever 4. At this time, welding is completed, and the controller controls the welding gun 13 to stop working, and at the same time controls the cylinder 2 14 and the cylinder 3 28 to work, so that the cylinder 3 28 drives the locking rod 29 away from the slide rod 27, unlocking the slide rod 27, and the cylinder 2 14 drives the slide plate 31 to move up and away from the touch switch 2 33, so that the slide plate 31 drives the pressure plate 10 to move up and reset through the spring 3 32, and the controller controls the cylinder 1 8 and the motor 23 to work, as shown in FIG. Figure 4 As shown, the cylinder 1 8 pushes the slider 35 and the screw 6 together through the push-pull rod 34, and the thread groove on the slider 35 engages with the external thread on the screw 6, thereby preventing the restoring force of the spring 25 from pushing the sleeve 7 to oscillate back and forth on the screw 6. At the same time, the motor 23 drives the screw 6 to rotate, so that the screw 6 drives the sleeve 7 to reset at a uniform speed through the thread transmission.

[0024] As described above, while the screw 6 rotates, the pump wheel 37 is driven to work, so that the pump wheel 37 transports air to the diverter pipe 1 39 and the diverter pipe 2 40 through the air pipe 38, so that the air in the diverter pipe 2 40 is ejected through the various nozzles 41 thereon to blow and clean the wing support frame to be welded, and the air in the diverter pipe 1 39 is ejected through the various nozzles 41 thereon to blow and clean and cool the welded wing support frame.

[0025] 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. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention.
