Description

Technical Field

[0001] The invention relates to the technical field of aviation material processing, in particular to a laser welding machine used for aviation material welding. Background Art

[0002] Laser welding utilizes high-energy laser pulses to locally heat a tiny area of ​​a material. The energy from the laser radiation diffuses into the material through heat conduction, melting the material and forming a specific molten pool. It is a new welding method primarily designed for welding thin-walled materials and precision parts. It can perform spot welding, butt welding, lap welding, and seal welding. It features a high aspect ratio, a narrow weld width, a small heat-affected zone, minimal deformation, fast welding speeds, and smooth, aesthetically pleasing welds. Post-weld treatment requires minimal or no treatment, resulting in high-quality welds with no porosity and precise control. Laser welding machines are widely used, particularly in the aviation material processing sector.

[0003] Aviation materials are relatively expensive, so the cost of welding errors is high. The welding of some aviation materials, such as thin plate splicing, requires welding two thin plates at a set angle. When the required connection angle changes, the staff needs to adjust the fixture. This process is cumbersome and reduces production efficiency. In addition, when the staff welds the sharp angles of aviation materials, due to the obstruction of the inclined plate, the brightness at this point may be insufficient, which makes it inconvenient for subsequent staff to weld here and observe the welding effect in real time. Summary of the Invention

The rubber block moves and squeezes the extrusion plate, so that the extrusion plate approaches and squeezes the tilting plate. The third spring is compressed, and the friction plate moves and squeezes the tilting plate. The tilting plate and the extrusion plate cooperate to fix the tilting plate and completely overcome its gravity. During the welding process, the bottom of the tilting plate is melted. The tilting plate and the extrusion plate cooperate to fix the tilting plate to prevent it from moving downward and affecting the cooling effect of the welding area.

DETAILED DESCRIPTION

[0030] To make the objectives, technical means, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0031] In order to better understand the above technical solution, the above technical solution will be described in detail below with reference to the accompanying drawings and specific implementation methods.

[0032] As shown in Figures 1-9, an embodiment of the present invention provides a laser welding machine for welding aviation materials, including a welding machine body 1, a base plate 6 and an inclined plate 7 are installed inside the welding machine body 1, two sets of base plate fixing mechanisms 4 for fixing the base plate 6 are installed on the outside of the base plate 6, and a visual angle adjustment mechanism 5 for driving the tilting angle to be adjusted is symmetrically installed on the outside of the tilting plate 7, so that the staff can view the connection angle of the base plate 6 and the tilting plate 7 in real time. The visual angle adjustment mechanism 5 includes a hollow frame 56, and a support plate 512 is symmetrically installed on the inner side of the hollow frame 56. The support plate 512 is inlaid with a rolling installation on one side close to the tilting plate 7. A steel ball 513 is provided to reduce the movement resistance of the tilting plate 7. An extrusion plate 517 for clamping the tilting plate 7 is slidably installed on the outer side of the support plate 512. A magnet 523 is slidably installed on the end of the hollow frame 56. A limit bar 521 is fixedly installed on the outer side of the magnet 523. A dial 527 is fixedly installed on the outer side of the limit bar 521. A pointer 528 that cooperates with the dial 527 to display the tilt angle is rotatably installed on the outer side of the limit bar 521. A light strip 526 is fixedly installed on the outer side of the magnet 523. The support plate 512 is closer to the middle of the hollow frame 56 than the extrusion plate 517. The tilting plate 7 is first squeezed by the support plate 512 and the steel ball 513.

[0033] In this embodiment, before welding, the two magnets 523 attract each other (they can also be brought close to and fitted together with the assistance of staff), and the magnets 523 move to pull out the light strip 526, and the light strip 526 fills the angle between the bottom plate 6 and the inclined plate 7, and rotates synchronously with the inclined plate 7 to ensure that there is sufficient light at the angle between the bottom plate 6 and the inclined plate 7, so that the staff can check the welding effect in real time. When problems occur in welding, the staff can promptly activate the emergency plan, and the dial 527 rotates synchronously with the inclined plate 7. Under the action of its gravity, the pointer 528 always points vertically downward. The staff can check the deflection angle of the inclined plate 7 in real time according to the dial 527, which is convenient and efficient, and is conducive to improving the work efficiency of the staff.

[0034] Specifically, the side of the extrusion plate 517 close to the inclined plate 7 is frosted to increase the friction between the extrusion plate 517 and the inclined plate 7. The limit bar 521 slides through the hollow frame 56. A transparent column 522 is fixedly installed on the outside of the magnet 523. The transparent column 522 is in the shape of a convex lens, thick in the middle and narrow on both sides. The welding part is magnified with a reference magnifying glass, which makes it convenient for staff to check the welding effect. The transparent column 522 slides through the hollow frame 56.

[0035] Specifically, a rotating column 524 is rotatably installed inside the hollow frame 56, and a coil spring 525 is installed on the outside of the rotating column 524. The inner end of the coil spring 525 is fixedly connected to the rotating column 524, and the outer end of the coil spring 525 is fixedly connected to the inner side of the hollow frame 56. The light strip 526 is wrapped around the outside of the rotating column 524. When the light strip 526 is pulled out, it drives the rotating column 524 to rotate, thereby causing the coil spring 525 to store force. When the tension on the light strip 526 disappears, the coil spring 525 drives the light strip 526 to reset and reel.

[0036] In this embodiment, after welding is completed, the magnet 523 is separated and reset under the drive of the coil spring 525.

[0037] Specifically, two linear guide rails 51 are symmetrically fixedly installed on the inner side of the welding machine body 1. The linear guide rails 51 are used for high-precision or high-speed linear reciprocating motion, and can bear a certain torque. They can achieve high-precision linear motion under high load conditions. They are relatively mature existing technologies and will not be described in detail herein. A slider 52 is slidably installed on the top of the linear guide rail 51, a motor 53 is fixedly installed on the top of the slider 52, a linkage plate 54 is fixedly installed on the outer side of the output end of the motor 53, and a second electric telescopic rod 55 is fixedly installed on the side of the linkage plate 54 away from the motor 53. The outer side of the telescopic end of the second electric telescopic rod 55 is fixedly installed. The side is frosted, and the telescopic end of the second electric telescopic rod 55 slides through the hollow frame 56. The telescopic end of the second electric telescopic rod 55 is fixedly installed with a friction plate 59. The side of the friction plate 59 close to the inclined plate 7 is frosted to increase the friction between the friction plate 59 and the inclined plate 7. The outside of the friction plate 59 is symmetrically fixed with an extrusion strip 510, and the inside of the extrusion strip 510 is inlaid and fixed with a rubber block 511. A plurality of limit rods 57 are fixedly installed on the outside of the hollow frame 56. The limit rod 57 slides through the linkage plate 54, and the end of the limit rod 57 away from the hollow frame 56 is fixed with a first baffle 58.

[0038] Specifically, a limiting slide 518 is symmetrically fixedly installed on the outside of the extrusion plate 517. The limiting slide 518 slides through the hollow frame 56. A third baffle 519 is fixedly installed on the end of the limiting slide 518 exposed from the hollow frame 56. A third spring 520 is fixedly installed between the third baffle 519 and the outside of the hollow frame 56 for resetting the extrusion plate 517. The third spring 520 is movably sleeved on the outer periphery of the limiting slide 518.

[0039] In this embodiment, the worker drives the inclined plate 7 to move horizontally to a desired position through the linear guide rail 51 .

[0040] After the angle of the inclined plate 7 is adjusted, the staff starts the second electric telescopic rod 55 again, and the first baffle 58 moves to fit with the linkage plate 54 and cannot move further, that is, the hollow frame 56 cannot move further. The second electric telescopic rod 55 drives the friction plate 59, the extrusion bar 510, and the rubber block 511 to continue to move. The rubber block 511 moves to squeeze the extrusion plate 517, so that the extrusion plate 517 approaches and squeezes the inclined plate 7. The third spring 520 is compressed, and the friction plate 59 moves to squeeze the inclined plate 7. The inclined plate 7 and the extrusion plate 517 cooperate to fix the inclined plate 7 and completely overcome its gravity. During the welding process, the bottom of the inclined plate 7 is melted, and the inclined plate 7 and the extrusion plate 517 cooperate to fix the inclined plate 7 to prevent it from moving downward and affecting the cooling effect of the welding area.

[0041] Specifically, a polygonal slide bar 514 is fixedly installed on the outside of the support plate 512, and the polygonal slide bar 514 slides through the hollow frame 56. A second baffle 515 is fixedly installed on the end of the polygonal slide bar 514 exposed from the hollow frame 56. A second spring 516 is fixedly installed between the second baffle 515 and the outside of the hollow frame 56 for resetting the support plate 512. The second spring 516 is movably sleeved on the outer periphery of the polygonal slide bar 514.

[0042] In this embodiment, to adjust the angle of the inclined plate 7, the staff places the inclined plate 7 above the base plate 6 and starts the second electric telescopic rod 55. The telescopic end of the second electric telescopic rod 55 extends, driving the hollow frame 56, the support plate 512, and the magnet 523 to move close to the inclined plate 7. The support plate 512 and the steel ball 513 move to squeeze the inclined plate 7. The polygonal slide bar 514 and the second baffle 515 move toward the outside of the hollow frame 56. The second spring 516 is stretched. The rolling steel ball 513 has little friction with the inclined plate 7, so the inclined plate 7 can slide. When the inclined plate 7 rotates, it can slide, and its bottom is always in contact with the base plate 6.

[0043] Specifically, a positioning block 8 that cooperates with the bottom plate fixing mechanism 4 is fixedly installed on the inner side of the welding machine body 1. The bottom plate fixing mechanism 4 includes a fixed block 42, which is fixedly installed on the inner side of the welding machine body 1. A first electric telescopic rod 41 is fixedly installed on the middle part of the fixed block 42. A connecting rod 43 is fixedly installed on the telescopic end of the first electric telescopic rod 41. Concave frames 44 are symmetrically fixedly installed on both ends of the connecting rod 43. A vertical rod 45 is fixedly installed on the inner side of the concave frame 44. A sliding plate 47 is slidably installed on the outer side of the vertical rod 45. A first spring 46 is fixedly installed between the top of the sliding plate 47 and the inner side of the concave frame 44. The first spring 46 is movably sleeved on the periphery of the vertical rod 45. An extrusion fixing plate 48 is fixedly installed on the end of the sliding plate 47. The extrusion fixing plate 48 is L-shaped, and the end of the extrusion fixing plate 48 away from the sliding plate 47 is inclined.

[0044] In this embodiment, to secure the base plate 6, the operator presses one corner of the base plate 6 against the positioning block 8 and then activates the first electric telescopic rod 41. The telescopic end of the first electric telescopic rod 41 extends, driving the connecting rod 43 and the extrusion fixing plate 48 toward the base plate 6. Because the end of the extrusion fixing plate 48 is tilted, when it is pressed against the base plate 6, the extrusion fixing plate 48 moves upward, driving the sliding plate 47 upward. The first spring 46 is compressed, causing the base plate 6 to be subjected to a downward extrusion force. The extrusion fixing plate 48 continues to move until its inner right angle is aligned with the base plate 6. At this point, the base plate 6 is dually secured horizontally and vertically, achieving a better fixation effect. During subsequent welding, the base plate 6 is more stable. The operating process of the two sets of base plate fixing mechanisms 4 is the same and will not be further described. After welding is completed, the operator activates the first electric telescopic rod 41 in the opposite direction, driving the extrusion fixing plate 48 to move away from the base plate 6. The extrusion fixing plate 48 is reset under the elastic force of the first spring 46.

[0045] Specifically, a laser welding mechanism 3 is installed inside the welding machine body 1, and a metal fume filtering mechanism 2 is installed outside the welding machine body 1 for absorbing and filtering the fume generated by welding.

[0046] How it works:

[0047] To fix the base plate 6, the staff presses one corner of the base plate 6 against the positioning block 8, and then starts the first electric telescopic rod 41. The telescopic end of the first electric telescopic rod 41 extends, driving the connecting rod 43 and the extrusion fixing plate 48 to approach the base plate 6. Since the end of the extrusion fixing plate 48 is inclined, when it is squeezed with the base plate 6, the extrusion fixing plate 48 moves up, driving the sliding plate 47 to move up, and the first spring 46 is compressed, so that the base plate 6 is subjected to a downward extrusion force, and the extrusion fixing plate 48 continues to move until its inner right angle is in contact with the base plate 6. At this time, the base plate 6 is doubly fixed horizontally and vertically, and the fixing effect is better. During subsequent welding, the base plate 6 is more stable. The working process of the two sets of base plate fixing mechanisms 4 is the same and will not be repeated.

[0048] To adjust the angle of the tilting plate 7, the staff places the tilting plate 7 above the bottom plate 6 and starts the second electric telescopic rod 55. The telescopic end of the second electric telescopic rod 55 extends, driving the hollow frame 56, the support plate 512, and the magnet 523 to move closer to the tilting plate 7. The support plate 512 and the steel ball 513 move to squeeze the tilting plate 7. The polygonal sliding rod 514 and the second baffle 515 move toward the outside of the hollow frame 56. The second spring 516 is stretched. The friction between the rolling steel ball 513 and the tilting plate 7 is small, and the tilting plate 7 can slide. The two magnets 523 attract each other (also The two plates 526 are connected by a screwdriver and the two plates 527 are connected by a screwdriver. The screwdriver 526 is connected by a screwdriver and the two plates 528 are connected by a screwdriver. The screwdriver 526 is connected by a screwdriver and the two plates 529 are connected by a screwdriver. The screwdriver 526 is connected by a screwdriver and the two plates 527 are connected by a screwdriver. The motor 53 rotates to drive the hollow frame 56, the dial 527, and the tilting plate 7 to rotate. The pointer 528 always points vertically downward under the action of its gravity. The staff can view the deflection angle of the tilting plate 7 in real time according to the dial 527, which is convenient and efficient, and is conducive to improving the work efficiency of the staff. When the tilting plate 7 rotates, it can slide, and its bottom is always in contact with the bottom plate 6. After the angle adjustment is completed, the staff starts the second electric telescopic rod 55 again, and the first baffle 58 moves to fit with the linkage plate 54 and cannot move further, that is, the hollow frame 56 cannot continue to move. Continuing to move, the second electric telescopic rod 55 drives the friction plate 59, the squeezing bar 510, and the rubber block 511 to continue to move. The rubber block 511 moves and squeezes the squeezing plate 517, so that the squeezing plate 517 approaches and squeezes the inclined plate 7. The third spring 520 is compressed, and the friction plate 59 moves and squeezes the inclined plate 7. The inclined plate 7 cooperates with the squeezing plate 517 to fix the inclined plate 7 and completely overcome its gravity. During the welding process, the bottom of the inclined plate 7 is melted, and the inclined plate 7 cooperates with the squeezing plate 517 to fix the inclined plate 7 to prevent it from moving downward and affecting the cooling effect of the welding area.

[0049] To adjust the position of the inclined plate 7 , the worker drives the inclined plate 7 to move horizontally to the desired position through the linear guide rail 51 .

[0050] After welding is completed, the staff starts the second electric telescopic rod 55 in the reverse direction. The telescopic end of the second electric telescopic rod 55 is shortened, driving the visualization angle adjustment mechanism 5 away from the tilting plate 7, and the magnet 523 is separated and reset under the drive of the coil spring 525. When the hollow frame 56 moves in the reverse direction to contact the fixed end of the second electric telescopic rod 55, it is rigidly blocked and no longer moves. The telescopic end of the second electric telescopic rod 55 continues to shorten, driving the friction plate 59, the extrusion strip 510, and the rubber block 511 to reset. The extrusion plate 517 is reset under the elastic force of the third spring 520, and the support plate 512 is reset under the elastic force of the second spring 516. The staff starts the first electric telescopic rod 41 in the reverse direction, driving the extrusion fixed plate 48 to move away from the bottom plate 6, and the extrusion fixed plate 48 is reset under the elastic force of the first spring 46.
