A convex rib 44 is fixed to the bottom surface of the pressure plate 43, and the convex rib 44 is correspondingly engaged with the rib groove.

[0023] Working principle and advantages of the present invention: When the aircraft landing bracket production and processing bending device is used, the working process is as follows: like Figures 1 to 5As shown, one end of the metal tube to be bent passes through between the supporting wheel 1 8 and the corresponding auxiliary wheel 34, and the other end passes through between the supporting wheel 2 9 and the corresponding auxiliary wheel 34, and the position is adjusted. Then, the motor 1 4 is started by the controller, so that the motor 1 4 drives the gear 2 32 to rotate through the gear 1 31, so that the gear 2 32 drives the screw 1 5 to move in the direction close to the bracket 22 through the thread transmission, so that the screw 1 5 drives the top wheel 7 to bend the metal tube. When the bending part of the metal tube is in contact with the touch switch 30 on the bracket 22, the touch switch 30 transmits the contact signal of the metal tube to the controller, and the controller controls the motor 1 4 to work in the reverse direction, so that the motor 1 4 drives the gear 2 32 to rotate in the reverse direction through the gear 1 31, so that the gear 2 32 drives the screw 1 5 to move in the direction away from the bracket 22 through the thread transmission and reset, thereby completing the bending of the metal tube, and the bent metal tube can be removed. The operation is simple and convenient.

[0024] When the length and bending angle of the metal tube need to be adjusted, the motor 2 12 is started by the controller. At this time, the motor 2 12 is energized, and the electromagnetic ring 41 is also energized to generate a magnetic force opposite to the lower surface of the magnetic block 37, so that the magnetic block 37 compresses the spring 38 and drives the column block 40 to move up through the push-pull rod 39, so that the column block 40 applies a pulling force to the lower end of the connecting rod 5 46 through the connecting rod 45, so that the connecting rod 6 47 drives the pressing plate 43 and the convex ridge 44 on the lower surface thereof to move up, so that the convex ridge 44 on the lower surface of the pressing plate 43 is moved upward. The rib 44 is separated from the rib groove and does not contact, and the lock on the moving seat 3 is released. The motor 2 12 drives the screw 2 10 to rotate while working, so that the screw 2 10 drives the slide 11 to move back and forth through the thread, and then the slide 11 drives the support wheel 2 9 to move closer to or away from the support wheel 1 8. Since the connecting rod 14 and the connecting rod 2 16 have the same structure and cooperate with the support rod 1 13 and the support rod 2 15, a parallel four-bar linkage is formed on both sides of the moving seat 3, so that the top wheel 7, the support wheel 1 8 and the support wheel 1 The center line of the wheel 29 is always an isosceles triangle. Then, loosen the fastening screw 21 so that the sleeve 20 can slide on the slide bar 219, thereby adjusting the position of the bracket 22, and adjusting according to different metal pipe lengths and bending angles, thereby improving the scope of use and greatly improving work efficiency. After the adjustment is completed, tighten the fastening screw 21 so that the sleeve 20 cannot slide on the slide bar 219, ensuring that the position of the bracket 22 is fixed. In addition, when the movable seat 3 moves horizontally to the right, it drives the slide plate 24 to slide to the right in the slide cylinder 23 through the push-pull rod 1 25, so that the slide plate 1 24 squeezes the oil in the slide cylinder 1 23 into the slide cylinder 27 through the conduit 26. Since the slide cylinder 1 23 and the slide cylinder 27 have exactly the same structure, the oil enters the slide cylinder 27 and pushes the slide plate 28 to move right through the slide plate 28 and the push-pull rod 29, and the moving distance is the same. In this way, the lateral distance and direction of the bracket 22 can be synchronized while the lateral distance of the moving top wheel 7 is maintained, saving time and effort.

[0025] When the adjustment is completed, the controller controls the motor 2 12 to stop working, the screw 2 10 stops rotating, and the electromagnetic ring 41 loses power and does not generate magnetic force, thereby driving the magnetic block to move down and reset under the action of the restoring force of the spring 38, so that the magnetic block 37 drives the column block 40 to move down through the push-pull rod 39, and then the column block 40 applies a push-pull force to the lower end of the connecting rod 5 46 through the connecting rod 45, so that the connecting rod 5 46 and the connecting rod 6 47 are in a straight line. At this time, the connecting rod 5 46 is tightly fitted against the inner side of the L-shaped bracket 42, and the connecting rod 45 is perpendicular to the connecting rod 5 46, so that the connecting rod 6 47 drives the pressure plate 43 to move down, so that the convex ridge 44 is engaged with the corresponding ridge groove, thereby realizing the locking of the movable seat 3, so as to maintain the stability of the movable seat 3 when the metal tube is bent.
