Description

Technical Field

[0001] This invention relates to the field of aircraft parts processing technology, specifically to a laser cleaning machine for aircraft fasteners. Background Technology

[0002] After an aircraft has been in service for a period of time, it needs to undergo corresponding inspections and maintenance. The parts of the aircraft are connected by fasteners, which are divided into rivets, bolts and pins. Fastener maintenance has always been a very important inspection step. Rusty fasteners are removed, and rusty fasteners that can still be used are derusted using a laser cleaning machine. Only after the fasteners have been derusted can they be installed.

[0003] Traditional laser cleaning machines for aircraft fasteners are equipped with a laser head for cleaning. A laser head guide wire is located at the tail end of the laser head, which emits a laser beam for cleaning. The operator holds the laser head and scans the rusted surface of the fastener. The laser removes rust from the rusted areas by moving the laser across the surface. Because lasers can be harmful to the human body, maintaining a high degree of stability while holding the laser head requires the operator to remain constantly tense. Cleaning a large number of fasteners is a significant physical challenge for the operator. When physical strength is exhausted, the scanning path of the laser head may deviate, resulting in some rusted areas of the fastener remaining uncleaned, leading to incomplete cleaning. Therefore, a new laser cleaning machine for aircraft fasteners is proposed. Summary of the Invention

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this invention provides a laser cleaning machine for aircraft fasteners, thereby solving the problems mentioned in the background section.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, the present invention provides the following technical solution: a laser cleaning machine for aircraft fasteners, comprising a support table, with support side plates fixed at both ends of the top of the support table, a support top plate fixed at one end of the support side plates away from the support table, a support back plate fixed at the rear end between the top ends of the support side plates, a limit support block fixed to the front side wall of the support back plate, a limit slot being chiseled at the top end of the limit support block on the side away from the support back plate, the number of limit slots being not less than four, limit spring ropes fixed at the four corners of the support top plate between the support side plates, and a laser platform fixedly connected to the top of the support table between the support side plates. The laser platform has a longitudinal groove at its front end and a transverse displacement groove at its rear end. A limiting support plate is located above the laser platform. Adjustable movement grooves are carved on both side walls of the limiting support plate, with two adjustment movement grooves at each end. Supporting moving blocks are located at both ends of the side walls of the limiting support plate. Support extension rods are fixed to the bottom of each supporting moving block, and limiting sliders are fixed to the bottom of each supporting extension rod. A support frame is fixed to the top of the limiting support plate, and a moving handle is fixed to the top of the support frame. The laser head body is inserted and fixed within the support frame of the limiting support plate.

[0008] Preferably, the distance between the front and rear ends of the transverse transposition groove is equal to the distance between the front and rear sidewalls of the limiting slider, and the limiting slider is slidably connected to the transverse transposition groove after intersecting.

[0009] Preferably, each of the adjusting movable slots is fixedly connected to a spring telescopic rod, and the supporting movable block is fixedly connected to the end of the spring telescopic rod that matches its position.

[0010] Preferably, the end of the limiting spring rope away from the supporting top plate is fixedly connected to the four top corners of the limiting support plate.

[0011] Preferably, the outer diameter of the limiting slider is equal to the inner diameter of the limiting slot, and the limiting slider and the support extension rod are respectively inserted and connected to the limiting slot.

[0012] Preferably, there are no fewer than eight longitudinal slide grooves, each of which communicates with a transverse transposition slide groove, and the limiting sliders are inserted into the longitudinal slide grooves and slidably connected to them.

[0013] Preferably, the top of one end of the laser head body, which passes through the limiting support plate, is connected to a laser head wire, and the end of the laser head wire away from the laser head body is fixed through and through the top side of the support frame.

[0014] (III) Beneficial Effects

[0015] Compared with the prior art, the present invention provides a laser cleaning machine for aircraft fasteners, which has the following advantages:

[0016] 1. Place the rusted fastener on top of the laser platform and below the laser head body. The laser head body moves the limit support plate down by the elasticity of the limit spring rope and by holding the moving handle, so that the limit slider is inserted into the longitudinal grooves at both ends of the fastener. By sliding the limit slider back and forth in the longitudinal grooves, the laser head body can ensure the accuracy of the cleaning path when scanning the fastener.

[0017] 2. If the rusted fasteners are large, a single movement cannot achieve complete cleaning. The limiting slider slides from the longitudinal groove to the transverse shifting groove. By sliding laterally within the transverse shifting groove, the limiting slider can move to another longitudinal groove. This allows the scanning position of the laser head to change its position within the longitudinal groove, achieving a better cleaning effect. Furthermore, by pulling the supporting moving blocks to opposite ends, the spring telescopic rod can extend, increasing the distance between the limiting sliders. This allows the limiting sliders to slide into different longitudinal grooves. The combined use of longitudinal and transverse shifting grooves can achieve an even better cleaning effect.

[0018] 3. After cleaning, the moving handle drives the limit support plate to rise due to the elasticity of the limit spring rope. The moving handle is then rotated away from the end of the limit support block, so that the position of the limit slider is close to the support back plate. The support extension rod and the limit slider are then inserted into the limit slot at a downward angle. The insertion of the limit slider into the limit slot makes the laser head body face away from the laser platform, which makes it convenient for workers to remove or replace the fasteners on the laser platform and provides a certain degree of protection.

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] This invention provides a technical solution: a laser cleaning machine for aircraft fasteners, such as... Figure 1 As shown, it includes a support platform 1, with support side plates 2 fixed at both ends of the top of the support platform 1. A support top plate 3 is fixed at one end of the support side plate 2 away from the support platform 1, and a support back plate 4 is fixed at the rear end between the top ends of the support side plates 2. Figures 2 to 4 As shown, a limiting support block 5 is fixed to the front side wall of the supporting back plate 4. A limiting slot 6 is chiseled at the top of the side of the limiting support block 5 away from the supporting back plate 4. The number of limiting slots 6 is not less than four. Limiting spring ropes 7 are fixed at the four corners of the supporting top plate 3 between the supporting side plates 2. A laser platform 18 is fixedly connected to the top of the supporting platform 1 between the supporting side plates 2. A longitudinal sliding groove 19 is chiseled at the front end of the top of the laser platform 18. A transverse displacement sliding groove 20 is chiseled at the rear end of the top of the laser platform 18. A limiting spring rope 7 is provided above the laser platform 18. The limiting support plate 8 has two adjustment and movement grooves 13 on each side wall. The limiting support plate 8 has two adjustment and movement grooves 13 at each end. The limiting support plate 8 has two support movement blocks 15 at each end of its side wall. The bottom of each support movement block 15 is fixed with a support extension rod 16. The bottom of each support extension rod 16 is fixed with a limiting slider 17. The top of the limiting support plate 8 is fixed with a support frame 9. The top of the support frame 9 is fixed with a moving handle 10. The laser head body 11 is inserted and fixed inside the support frame 9.

[0026] The distance between the front and rear ends of the transverse shifting slide 20 is equal to the distance between the front and rear side walls of the limiting slider 17. The limiting slider 17 is inserted into and slidably connected to the transverse shifting slide 20, which makes it convenient for the laser head body 11 to adjust its position by moving the limiting slider 17 laterally within the transverse shifting slide 20 during multi-position cleaning.

[0027] Spring telescopic rods 14 are fixedly connected inside the adjusting moving groove 13. The supporting moving block 15 is fixedly connected to the end of the spring telescopic rod 14 that matches the position. The extension and retraction of the spring telescopic rod 14 can drive the distance between the supporting moving blocks 15 to be adjusted, thereby increasing the distance between the limiting sliders 17. This allows the limiting sliders 17 to slide into different longitudinal sliding grooves 19. With the use of the longitudinal sliding grooves 19 and the transverse shifting sliding grooves 20, a better cleaning effect can be achieved.

[0028] The end of the limiting spring rope 7 away from the supporting top plate 3 is fixedly connected to the four top corners of the limiting support plate 8, so as to provide an elastic limiting effect for the limiting support plate 8.

[0029] The outer diameter of the limiting slider 17 is equal to the inner diameter of the limiting slot 6, and the limiting slider 17 and the support extension rod 16 are respectively inserted into the limiting slot 6. After cleaning, the limiting slider 17 is inserted into the limiting slot 6 so that the laser head body 11 faces away from the laser platform 18, which makes it convenient for staff to remove or replace the fasteners on the laser platform 18, and plays a certain protective role.

[0030] There are no fewer than eight longitudinal slide grooves 19. Each longitudinal slide groove 19 is connected to a transverse transposition slide groove 20. Each limiting slider 17 is inserted into the longitudinal slide groove 19 and slidably connected to it. This allows the scanning position of the laser head body 11 to be changed by the limiting slider 17 moving within the transverse transposition slide groove 20, thereby achieving a better cleaning effect.

[0031] The top of one end of the laser head body 11, which passes through the limiting support plate 8, is connected to a laser head wire 12. The end of the laser head wire 12 away from the laser head body 11 is fixed through the top side of the support frame 9, which facilitates limiting the laser head wire 12 and prevents the drooping laser head wire 12 from affecting the movement of the laser head body 11 when it moves.

[0032] The working principle of this device is as follows: The corroded fastener is placed on top of the laser platform 18 and below the laser head body 11. The laser head body 11, through the elasticity of the limiting spring rope 7 and the grip of the moving handle 10, causes the limiting support plate 8 to descend, allowing the limiting slider 17 to insert into the longitudinal grooves 19 located at both ends of the fastener. The sliding of the limiting slider 17 within the longitudinal grooves 19 ensures the accuracy of the cleaning path when the laser head body 11 scans the fastener. If the corroded fastener is large, a single movement may not be sufficient for complete cleaning. The limiting slider 17 then slides from the longitudinal groove 19 into the transverse transposition groove 20. This transverse sliding allows the limiting slider 17 to move within the transverse transposition groove 20 to another longitudinal groove 19, thus allowing the laser head body 11 to move its scanning position within the transverse transposition groove 20 and thus target the corresponding longitudinal groove. The position of the slide 19 is changed to achieve a better cleaning effect. By pulling the support moving block 15 to the opposite end, the spring telescopic rod 14 can be extended, thereby increasing the distance between the limit sliders 17. This allows the limit sliders 17 to slide into different longitudinal slides 19. The use of the longitudinal slides 19 and the transverse shifting slide 20 can achieve a better cleaning effect. After cleaning, the moving handle 10 drives the limit support plate 8 to rise through the elasticity of the limit spring rope 7. The moving handle 10 is rotated to the end away from the limit support block 5, so that the position of the limit slider 17 is close to the support back plate 4. The support extension rod 16 and the limit slider 17 are inserted into the limit slot 6 at a downward angle. The insertion of the limit slider 17 into the limit slot 6 makes the laser head body 11 face away from the laser platform 18, which makes it convenient for the staff to remove or replace the fasteners on the laser platform 18 and provides a certain degree of protection.
