Description

Technical Field

[0001] The present invention relates to the technical field of aviation component detection, and in particular to an aviation component defect detection device. Background Art

[0002] In the prior art, there are many drawbacks in the inspection process of aviation parts such as truss structure tubes. Traditional inspection methods mostly rely on manual visual inspection or semi-automatic inspection equipment, which leads to low inspection efficiency and is difficult to meet the needs of modern aviation manufacturing industry for high-efficiency production. In addition, the consistency of manual inspection is poor and is easily affected by the operator's experience and technical level, making it difficult to ensure that the inspection quality of each truss structure tube meets uniform standards. Long-term manual inspection will also cause visual and physical fatigue of the operator and increase labor intensity. Traditional equipment can often only adapt to truss structure tubes of specific sizes or shapes, and it is difficult to cope with various types of inspection needs. Once a failure occurs, the complex positioning and inspection components make the maintenance and replacement costs high. Therefore, we propose an aviation parts defect detection device.

Two sliding sleeves 432 corresponding to the positions of the transverse slide rails 42 are fixedly installed at the rear end of each adjustment plate 431, and the two sliding sleeves 432 are respectively slidably connected with the two transverse slide rails 42 to slide the adjustment plate 431 on the side of the positioning plate 41 away from the fixed plate 1. The opposite ends of the two adjustment plates 431 can be detachably installed with positioning bodies 436; the upper and lower sides of the opposite ends of the two adjustment plates 431 are respectively fixedly installed with a No. 1 transmission rack 433 and a No. 2 transmission rack 435, and the No. 1 transmission rack 433 and the No. 2 transmission rack 435 on the same side are staggered up and down, and the No. 1 transmission rack 433 and the No. 2 transmission rack 435 on the same side are meshed and connected with a transmission gear 434; one adjustment plate 431 is provided with two No. 1 limiting grooves 4311 adapted to the No. 1 transmission rack 433, and the other adjustment plate 431 is provided with two No. 2 limiting grooves 4312 adapted to the No. 2 transmission rack 435, the No. 1 transmission rack 433 is slidably connected in the corresponding No. 1 limiting groove 4311 and the No. 2 transmission rack 435 is slidably connected in the corresponding No. 2 limiting groove 4312 to slide and connect the two adjustment plates 431 together; the structure of the longitudinal positioning member 48 is the same as that of the transverse positioning member 43, and the connection method of the longitudinal positioning member 48 and the longitudinal slide rail 47 is the same as the connection method of the transverse positioning member 43 and the transverse slide rail 42.

[0047] Through the above scheme: the truss structure tube to be tested in the aircraft structure is passed through the through slots 411 on the front and rear positioning mechanisms 4, the No. 1 electric telescopic rod 45 is started, and the No. 1 electric telescopic rod 45 is extended to push the adjustment plate 431 in the transverse positioning member 43 to slide along the transverse slide rail 42 to one side of the through slot 411. At this time, the No. 1 transmission rack 433 connected to the adjustment plate 431 slides in the No. 1 limiting slide groove 4311. During the movement of the No. 1 transmission rack 433, the No. 1 transmission rack 433 is meshed with the transmission gear 434, so that the No. 2 transmission rack 435 slides in the No. 2 limiting slide groove 4312 to drive the adjustment plate 431 on the other side to extend the transverse slide rail 4 2 moves to the side close to the through slot 411, and the two adjusting plates 431 move synchronously to enable the positioning pulleys 4365 on the two positioning bodies 436 to position the truss structure tube to be detected laterally.

[0049] Through the above scheme: during the defect detection process, start the No. 1 drive motor 4366, and drive the positioning pulley 4365 to rotate through the No. 1 drive motor 4366. The truss structure tube positioned in the middle of the through groove 411 is smoothly transported by the rotation of the positioning pulley 4365, and cooperates with the detection mechanism 6 to complete the surface defect detection of the entire truss structure tube.

As the rotating disk 63 rotates, the industrial camera 66 installed in the rotating disk 63 can take photos or videos of the positioned truss structure tube to be inspected in all directions, and perform surface defect detection on the truss structure tube without blind spots. At the same time, the flexible light strip 65 installed in the rotating disk 63 provides uniform and stable lighting to ensure the shooting quality of the industrial camera 66 at different angles.

[0052] During use, this embodiment specifically includes the following steps:

[0053] S1.

During the movement of the No. 1 transmission rack 433, the No. 1 transmission rack 433 is meshed with the transmission gear 434, so that the No. 2 transmission rack 435 slides in the No. 2 limiting slide groove 4312, driving the adjustment plate 431 on the other side to extend the transverse slide rail 42 to move to the side close to the through slot 411. The two adjustment plates 431 move synchronously, so that the positioning pulleys 4365 on the two positioning bodies 436 are transversely positioned for the truss structure tube to be inspected;

[0054] S2, start the No. 2 electric telescopic rod 50, extend the No. 2 electric telescopic rod 50 to push the No. 2 push plate 51, and then push the adjustment plate 431 in the longitudinal positioning member 48 to move along the longitudinal slide rail 47, and use the same method as S1 to make the two positioning pulleys 4365 on the longitudinal positioning member 48 to longitudinally position the truss structure pipe to be tested, which not only ensures the stable positioning of the truss structure pipe to be tested, but also makes the truss structure pipe to be tested coaxially positioned with the fixed plate 1 and the positioning plate 41;

[0055] S3, start the second drive motor 61, drive the driving gear 62 to rotate through the second drive motor 61, and drive the rotating disk 63 to rotate through the engagement of the driving gear 62 and the driven gear 64. As the rotating disk 63 rotates, the industrial camera 66 installed in the rotating disk 63 can take photos or videos of the positioned truss structure tube to be inspected in all directions, and perform surface defect detection on the truss structure tube without blind spots. At the same time, the flexible light strip 65 installed in the rotating disk 63 provides uniform and stable lighting to ensure the shooting quality of the industrial camera 66 at different angles;

[0056] S4. During the defect detection process, start the No. 1 driving motor 4366, and drive the positioning pulley 4365 to rotate. The positioning pulley 4365 rotates to smoothly transport the truss structure tube positioned in the middle of the through groove 411, and cooperate with the detection mechanism 6 to complete the surface defect detection of the entire truss structure tube.
