Description

Technical Field

[0001] This utility model relates to the field of laser welding technology, and in particular to a composite beam shaping device for laser welding of dissimilar metals. Background Technology

[0002] With the widespread application of laser welding technology in various industries, composite beam shaping devices have also developed and emerged. In certain modes, such as deep penetration welding, the dynamic effects that typically occur cause the molten pool to move and spray, resulting in spatter. Some precision welding processes require a very small laser focal diameter, necessitating precise clamping devices to maintain the weld gap within a very small range. Composite beam shaping devices can reshape the laser beam, adjusting parameters such as its spot shape and energy distribution to adapt to different welding process requirements, thereby improving the stability and reliability of the welding process.

[0003] The rise of composite beam shaping devices has brought more convenient implementation methods to laser welding technology. However, most of the composite beam shaping devices on the market at present need to be installed by traditional threads, or are manufactured as a whole by casting along with the laser emitter, which means that the shaping device cannot be disassembled. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a composite beam shaping device for laser welding of dissimilar metals, aiming to improve the problem that the shaping device cannot be disassembled.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a composite beam shaping device for laser welding of dissimilar metals, comprising a laser emitter, an outer shell fixedly connected to the outside of the laser emitter, a radio rail opened inside the outer shell, a convex mirror fixedly connected inside the radio rail, a concave mirror fixedly connected inside the radio rail, an emission port opened at the bottom of the radio rail, a collar slidably connected to the bottom of the outer shell, and a disassembly assembly slidably connected inside the collar.

[0006] Preferably, the disassembly assembly includes a button, the button being slidably connected to the inside of a collar, a diamond-shaped wheel rod being fixedly connected to one side of the button, sliders being fixedly connected to both sides of the diamond-shaped wheel rod, a spring being provided on the outside of the sliders, the other end of the spring being fixedly connected to the inside of the collar, a locking block being fixedly connected to the other end of the diamond-shaped wheel rod, and a locking groove being provided at the bottom of the outer casing, with the locking block engaging with the inside of the locking groove.

[0007] Preferably, the bottom of the collar is fixedly connected to a threaded ring, and the external thread of the threaded ring is connected to a shaft collar.

[0008] Preferably, a lens is provided at the bottom of the collar.

[0009] Preferably, the collar has a threaded groove inside, and a baffle is fixedly connected to the outside of the threaded collar.

[0010] Preferably, the threaded ring has a groove inside, and a rack is slidably connected inside the groove.

[0011] Preferably, a second spring is provided on the side of the rack, and the other end of the second spring is fixedly connected to the inside of the threaded ring.

[0012] Preferably, the collar has a second groove inside, and the toothed end of the rack is engaged inside the second groove.

[0013] This utility model has the following beneficial effects:

[0014] 1. In this utility model, when the beam shaping device is disassembled, pressing the button causes the rhomboid wheel rod to deform, the slider connected in the middle slides and drives the spring to contract, which in turn drives the locking block at the other end to contract inward and be pulled out from the inside of the locking groove, so that the outer shell can be taken out from the inside of the collar. Then the spring rebounds and the locking block returns to its original position, thus achieving the purpose of disassembling the beam shaping device.

[0015] 2. In this utility model, when the welding spot does not align with the metal during the welding process, the rotating collar is rotated to move down or up along the thread on the outer wall of the threaded ring, thereby changing the distance between the lens installed inside the collar and the laser emission port, thus achieving the purpose of changing the laser spot.

[0023] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0024] Reference Figures 1-3 An embodiment of this utility model provides a composite beam shaping device for laser welding of dissimilar metals, comprising a laser emitter 1, an outer shell 2 fixedly connected to the outside of the laser emitter 1, a radio rail 3 opened inside the outer shell 2, a convex mirror 4 fixedly connected inside the radio rail 3, a concave mirror 5 fixedly connected inside the radio rail 3, an emission port 6 opened at the bottom of the radio rail 3, a collar 7 slidably connected to the bottom of the outer shell 2, and a disassembly assembly 8 slidably connected inside the collar 7.

[0025] Specifically, when the laser welding is started, the laser emitter 1 operates and emits a laser beam, which passes through the convex mirror 4 and concave mirror 5 inside the radio rail 3 and finally reaches the emission port 6 and is emitted. The two beams converge at one point to weld the metal.

[0026] Reference Figures 1-3 The disassembly assembly 8 includes a button 81, the outside of which is slidably connected to the inside of the collar 7. A diamond-shaped wheel rod 82 is fixedly connected to one side of the button 81. Slider 83 is fixedly connected to both sides of the diamond-shaped wheel rod 82. A spring 84 is provided on the outside of the slider 83. The other end of the spring 84 is fixedly connected to the inside of the collar 7. A locking block 85 is fixedly connected to the other end of the diamond-shaped wheel rod 82. A locking groove 86 is provided at the bottom of the outer casing 2. The outside of the locking block 85 is locked into the inside of the locking groove 86.

[0027] Specifically, when the beam shaping device needs to be disassembled, pressing the buttons 81 on both sides deforms the rhomboid wheel rod 82, causing the slider 83 and spring 84 connected in the middle to retract, causing the two sides of the rhomboid wheel rod 82 to retract inward, driving the locking block 85 at the other end to retract inward and be pulled out from the inside of the locking groove 86, releasing the restriction of the outer shell 2, allowing it to slide out from the inside of the collar 7. Then the spring 84 rebounds, and the locking block 85 returns to its original position, achieving the purpose of disassembling the beam shaping device.

[0028] Reference Figures 4-5 A threaded ring 11 is fixedly connected to the bottom of the collar 7. A shaft collar 9 is threadedly connected to the outside of the threaded ring 11. A lens 10 is provided at the bottom of the shaft collar 9. A threaded groove 12 is provided inside the shaft collar 9. A baffle 13 is fixedly connected to the outside of the threaded ring 11. A sliding groove 14 is provided inside the threaded ring 11. A rack 15 is slidably connected inside the sliding groove 14. A second spring 16 is provided on the side of the rack 15. The other end of the second spring 16 is fixedly connected to the inside of the threaded ring 11. A second retaining groove 17 is provided inside the shaft collar 9. The tooth end of the rack 15 is engaged inside the second retaining groove 17.

[0029] Specifically, during the metal welding process, if the welding spot does not align with the metal, the rotating collar 9 rotates along the thread on the outer wall of the threaded ring 11 to descend or ascend, thereby changing the distance between the lens 10 installed inside the collar 9 and the laser emission port 6, thus changing the laser spot. When rotating upward too much, the baffle 13 will block the collar 9, preventing it from rising further. When rotating downward too much, the rack 15 will be engaged in the slot 17 by the action of the second spring 16. The tooth tip of the rack 15 is inclined, allowing it to return and continue to rotate upward, but preventing it from rotating downward.

[0030] Working principle: When the beam shaping device needs to be disassembled, pressing button 81 causes the rhomboid wheel rod 82 to deform, the slider 83 and spring 84 connected in the middle to retract, the two ends of the rhomboid wheel rod 82 retract inward, driving the locking block 85 at the other end to retract inward, and pull it out from the inside of the locking groove 86, so that the outer shell 2 is released from restriction and can slide out from the inside of the collar 7. Then the spring 84 rebounds, and the locking block 85 returns to its original position, thus achieving the purpose of disassembling the beam shaping device.

[0031] When the welding spot does not align with the metal during the welding process, the rotating collar 9 is rotated to move down or up along the thread on the outer wall of the threaded ring 11, thereby changing the distance between the lens 10 installed inside the collar 9 and the laser emission port 6, thus achieving the purpose of changing the laser spot.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
