[0002] With the development of laser technology, lasers have been widely used in various industries, among which laser cleaning is very common. Compared with traditional cleaning methods, laser cleaning is a "green" cleaning method that can avoid environmental pollution caused by chemical cleaning. Laser cleaning is a non-contact cleaning method that avoids mechanical damage to the surface of the object being cleaned. At the same time, it can be easily operated over a long distance, with high cleaning efficiency and time saving. Therefore, more and more fields use lasers for cleaning.
[0003] In the service environment, aircraft will inevitably produce metal corrosion and cause local paint failure. In order to ensure the expected life of the aircraft, corrosion products and failed paint layers must be cleaned thoroughly on a regular basis. Based on safety requirements, aircraft in-situ laser cleaning requires that the cleaning position is precisely controllable, the substrate material is not damaged, and the damage to the original protection system of the non-essential cleaning area is minimized. In turn, basic requirements for the precise control of the working distance, moving trajectory, and cleaning boundary during the cleaning operation are proposed. At the same time, it should also meet the requirements of visual cleaning positioning and convenient operation.
[0004] Existing laser cleaning tools are mostly handheld for easy mobility. However, during the actual cleaning process, as the laser cleaning tool moves on the surface of the object being cleaned, the distance between the laser light outlet and the surface of the object being cleaned cannot be controlled, which makes it impossible to ensure the consistency of the processing effect. Some parts cannot be cleaned cleanly, and some parts even have surface damage, which cannot meet the high-quality cleaning and processing requirements. Summary of the invention

[0038] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.
[0039] like Figure 1 As shown, an aircraft in-situ laser cleaning auxiliary tooling includes a tooling body 1 with a hollow interior, a laser generating component 2, a support component 3 with a hollow middle portion, and a walking component 4, wherein one end of the tooling body 1 is provided with a light emitting hole for the laser to pass through, the laser generating component 2 is arranged in the tooling body 1, one end of the support component 3 is connected to the outer wall of one end of the tooling body 1 provided with the light emitting hole, the other end of the support component 3 is installed with the walking component 4, and the middle portion of the walking component 4 is provided with a through hole for the laser to pass through and irradiate the surface of the cleaning object, the laser emitted by the laser generating component 2 passes through the light emitting hole and then irradiates the surface of the cleaning object through the through hole in sequence, and cleans the surface of the cleaning object as the walking component 4 moves on the surface of the cleaning object.
[0040] The aircraft in-situ laser cleaning auxiliary tooling of the present invention arranges the laser generating component 2 in the tooling body 1, and emits laser from the light emitting hole, passes through the through hole on the walking component 3 and reaches the surface of the cleaning object. The walking component 4 can be used to move on the surface of the cleaning object more conveniently, thereby reducing labor intensity. The support component 3 can ensure that the distance from the light emitting hole to the surface of the cleaning object is constant, and the cleaning position can be kept constant, thereby improving the cleaning efficiency and ensuring the cleaning effect.
[0041] In practice, in the present invention, a hand-held portion 7 is provided at the other end of the tool body 1, and the hand-held portion 7 is combined with the tool body 1 to form a "7"-shaped structure, which is convenient for hand-held movement, small in size, and easy to carry.
[0042] like Figure 2As shown, in one or more embodiments of the present invention, the laser generating assembly 2 includes a laser light source 21, a galvanometer 22, a beam combiner 23 and a controller 24. The laser light generated by the laser light source 21 passes through the galvanometer 22 and the beam combiner 23 in sequence and then exits from the light exit hole. The controller 24 is electrically connected to the laser light source 21 and the galvanometer 22, respectively. The laser light is generated by the laser light source 21, and after being reflected by the galvanometer 22 and the beam combiner 23, it passes through the through hole and reaches the surface of the object to be cleaned. At the same time, the controller 24 can control the parameters of the laser light emitted by the laser light source 21 and the working parameters of the galvanometer to ensure that the emitted laser light meets the cleaning requirements.
[0043] Here, the galvanometer 22 includes an X galvanometer and a Y galvanometer, and the X galvanometer and the Y galvanometer are sequentially arranged between the laser light source 21 and the beam combiner 23 along the optical path. The initial positions of the X galvanometer and the Y galvanometer are parallel to the position of the beam combiner 23, and the angle between the initial position of the X galvanometer and the laser beam is 45 degrees. The angle between the beam combiner 23 and the indicator light beam emitted by the rangefinder 6 is 45 degrees. By setting the X galvanometer and the Y galvanometer, the laser emitted by the laser light source 21 can be deflected in the X-axis direction and the Y-axis direction, respectively, so that the laser can be smoothly incident on the beam combiner 23 and reflected to the surface of the cleaning object, so that the direction and deflection angle of the laser can be adjusted more conveniently.
[0044] Optionally, in one or more embodiments of the present invention, the aircraft in-situ laser cleaning auxiliary tooling further includes a lens cover 5, a plurality of first guide posts are arranged at intervals along the laser emission direction on the outer wall of the light exit hole, a first guide groove matching and corresponding to the first guide post is arranged on the inner wall of the lens cover 5, the lens cover 5 is detachably arranged at one end of the tooling body 1, and when the lens cover 5 is arranged at one end of the tooling body 1, the lens cover 5 can cover the light exit hole, and the first guide posts are embedded in the corresponding first guide grooves one by one. By setting the lens cover 5 to cover the light exit hole, when not in operation, external dust can be effectively prevented from entering and affecting the normal operation of the laser generating assembly 2, thereby improving the working stability of the laser generating assembly 2.
[0045] Optionally, in one or more embodiments of the present invention, a protrusion 11 matching the lens cover 5 is provided on the other end of the tool body 1 relative to the light exit hole, and a plurality of second guide posts matching the first guide groove are provided at intervals on the outer wall of the protrusion 11, and when the lens cover 5 is covered on the protrusion 11, the second guide posts can be embedded in the first guide groove of the lens cover 5 one by one. By setting the lens cover 5 to cover the protrusion 11, the lens cover 5 can be removed and buckled on the protrusion 11 in the working state to prevent careless loss.
[0046] like Figures 3 to 5 As shown, in one or more embodiments of the present invention, the support assembly includes an annular sleeve 31 and two support frames 32, the sleeve 31 is sleeved on the outer wall of one end of the tool body 1 provided with the light exit hole, the two support frames 32 are respectively arranged on opposite sides of the sleeve 31, and one end of the support frame 32 is respectively connected and fixed to the outer wall of the corresponding side of the sleeve 31, and the other end of the support frame 32 is connected to the corresponding side of the walking assembly 4. By sleeved the annular sleeve 31 on the tool body 1, one end of the support frame 32 can be installed on the tool body 1, thereby ensuring the support stability of the walking assembly 4, and realizing the stable walking of the entire tool equipment on the surface of the cleaning object.
[0047] Optionally, in one or more embodiments of the present invention, the sleeve 31 is movably connected to the outer wall of one end of the tooling body 1 on which the light exit hole is provided, and the sleeve 31 can be moved relative to the outer wall of one end of the tooling body 1 in a direction parallel to the laser emission direction to adjust the distance between the surface of the object to be cleaned and the light exit hole. By movably connecting the sleeve 31 to the outer wall of one end of the tooling body 1 on which the light exit hole is provided, it is convenient to move the sleeve 31 relative to the outer wall of one end of the tooling body 1 in a direction parallel to the laser emission direction, thereby adjusting the distance between the surface of the object to be cleaned and the light exit hole, ensuring that the surface of the object to be cleaned and the focal plane of the laser are in the same plane, improving the energy utilization of the laser, and improving the cleaning efficiency.
[0048] Specifically, in one or more embodiments of the present invention, a plurality of third guide grooves are arranged on the outer wall of one end of the tool body 1 at intervals parallel to the laser emission direction, a third guide column matching and corresponding to the third guide groove is arranged on the inner wall of the sleeve 31, and the third guide column is embedded in the corresponding third guide groove one by one, a waist hole is penetrated on the side wall of the sleeve 31, a plurality of fixing holes are arranged on the outer wall of one end of the tool body 1, and the sleeve 31 is connected to the tool body 1 through a stud passing through the waist hole and connected to the fixing thread. By arranging the third guide groove on the outer wall of one end of the tool body 1, and arranging the third guide column matching and corresponding to the third guide groove on the inner wall of the sleeve 31, the stability of the movement of the sleeve 31 on the tool body 1 can be ensured, and the distance between the light exit hole and the surface of the cleaning object can be adjusted while the sleeve 31 moves, so as to match different focal lengths and facilitate adjustment.
[0049] In one or more embodiments of the present invention, the walking component 4 includes a walking body 41, two casters 42 and two bull's eyeballs 43. The two sides of the walking body 41 are rotatably connected to the other end of the support frame 32. The two casters 42 and the two bull's eyeballs 43 are respectively arranged at the four corners of the walking body 41, and the two casters 42 and the two bull's eyeballs 43 are respectively arranged adjacent to each other. The middle part of the walking body 41 is provided with the through hole for the laser to pass through and irradiate the surface of the cleaning object. By arranging casters 42 and bull's eyeballs 43 around the walking body 41, it is convenient for the walking body 41 and the entire tooling equipment to walk, reduce walking resistance, and facilitate turning. At the same time, during the walking process, the laser emitted by the laser generating component 2 stably irradiates the middle part of the walking body 41.
[0050] like Figure 6 As shown, in one or more embodiments of the present invention, the walking component 4 also includes a baffle 44 for shielding the area outside the cleaning area of the cleaning object surface, and a slot parallel to the surface of the walking body 41 and passing through the through hole, and the baffle 44 is detachably arranged in the slot, and a light-through hole is arranged in the middle of the baffle 44, and the light-through hole is located in the through hole. By setting the baffle 44, the laser can only pass through the light-through hole in the middle of the baffle 44 and irradiate the cleaning object surface, which plays a role in indicating and limiting the range of irradiation to the cleaning object surface, and is convenient for control. In addition, the baffle 44 corresponding to different light-through hole sizes can be replaced according to different cleaning scenes and needs, which is very convenient.
[0051] Optionally, in one or more embodiments of the present invention, the walking component 4 further includes a locking spring pin 45, which is disposed on the surface of the walking body 41, and is inserted into a card slot in the walking component 4, and can lock the blocking piece 44. The blocking piece 44 inserted into the card slot in the walking component 4 can be locked by the locking spring pin 45, ensuring that the position phase of the blocking piece 44 and the light-through hole in the middle thereof are stable during operation, thereby ensuring the accuracy of cleaning.
[0052] In one or more embodiments of the present invention, the aircraft in-situ laser cleaning auxiliary tooling further includes a rangefinder 6, which is disposed on the tooling body 1 and is used to measure the distance between the light-emitting hole at one end of the tooling body 1 and the surface of the object to be cleaned, and the rangefinder 6 is electrically connected to the laser generating assembly 2. The distance between the light-emitting hole and the surface of the object to be cleaned can be measured in real time by the rangefinder 6, so that the laser generating assembly 2 can emit light when the distance between the light-emitting hole and the surface of the object to be cleaned is within the working range, and automatically cut off the light when it exceeds the working range, thereby ensuring the safety of the laser cleaning equipment and also facilitating the improvement of energy utilization.
[0053] The indicator light emitted by the rangefinder 6 irradiates the surface of the cleaning object and then returns along the original path and is received by the rangefinder 6. In this way, the distance between the light outlet and the surface of the cleaning object can be measured by the relative position relationship between the rangefinder and the light outlet.
[0054] In practice, the rangefinder 6 is connected to the outer wall of the tooling body 1 through an adapter plate 8. In order to facilitate the adjustment of the rangefinder, a waist-shaped hole is provided on the adapter plate 8, and the rangefinder 6 is fixed by a stud passing through the waist-shaped hole. By loosening the stud, the rangefinder 6 can be fine-tuned more conveniently, so that the indicator light emitted by the rangefinder 6 can smoothly reach the through hole in the middle of the walking body 1, thereby facilitating the measurement of the distance between the light-emitting hole and the surface of the cleaning object.
[0055] In an embodiment of the present invention, the rangefinder 6 is arranged outside the tooling body 1. This is because the volume of the rangefinder 6 is larger than that of the tooling body 1 and it is inconvenient to place it inside the tooling body 1. In practice, if the volume of the entire tooling equipment is not considered, the rangefinder 6 can be arranged inside the tooling body 1 to improve the integrity of the entire tooling equipment.
[0056] It should be pointed out that when the rangefinder 6 is arranged in the tooling body 1, the emitted indicator light can be coaxially arranged with the laser emitted by the laser light source 21 and irradiated to the surface of the cleaning object. In this way, the distance from the light output hole to the surface of the cleaning object can be accurately obtained. Even if the surface of the cleaning object is non-planar, the distance from the light output hole to the center point of the cleaning object can still be accurately measured.
[0057] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
