Description

Technical Field

[0001] This invention relates to the field of laser cladding technology, and more specifically to multi-condition collaborative integrated laser cladding metal additive manufacturing equipment. Background Technology

[0002] In the field of laser cladding technology, the nozzle, as the core actuator for achieving precise interaction between laser energy and the cladding material, directly determines the efficiency, cost, and applicability of the cladding operation through its structural design and functional adaptability. Currently, several patents related to laser cladding nozzles have been disclosed in the existing technology, such as the laser broadband cladding device (CN106444049A), a laser internal wire feeding device for laser cladding (CN105562951A), a laser cladding device (CN107627002A), a laser cladding device (CN107217257A), and a laser multi-beam cladding device (CN106583726A). The nozzle technologies protected by these disclosed patents are all designed for specific single working conditions and can only be adapted to laser cladding work in a specific scenario. They have significant limitations in actual industrial applications, as detailed below: 1. Because the nozzles in the aforementioned existing patents are all "single-condition dedicated" structures, when the cladding operation needs to switch from one condition to another, the original nozzle must be completely disassembled and reassembled with a dedicated nozzle adapted to the new condition. Furthermore, a series of auxiliary operations such as beam calibration and coaxiality adjustment are required after reassembly. This process is not only cumbersome but also time-consuming per switch, severely disrupting the continuity of the cladding operation and significantly reducing overall work efficiency, making it difficult to meet the demands of large-scale, multi-condition alternating industrial production.

[0003] 2. In order to reduce the tedious work of disassembly, assembly, and debugging and improve work efficiency, each special nozzle in the existing patent can be equipped with an independent beam collimation device so that it can be directly replaced for different working conditions. However, since the beam collimation device is the core component of the nozzle, too many beam collimation devices, if they are not universal, will result in the repeated investment in key components, thereby increasing the overall purchase cost and subsequent maintenance cost of the laser cladding equipment, resulting in relatively high costs. Summary of the Invention

[0004] This invention provides a multi-condition collaborative integrated laser cladding metal additive manufacturing equipment to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows: A multi-condition collaborative integrated laser cladding metal additive manufacturing equipment includes a bracket for connecting to a robotic arm, a collimator device mounted on the bracket and connected to a laser head, and a rotating module for driving multiple nozzle assemblies to rotate and connected to the bracket. Multiple nozzle assemblies are fixedly mounted on the rotating module. Through the rotation of the rotating module, the nozzles of the multiple nozzle assemblies can be coaxially aligned with the beam emitted from the collimator device.

[0006] Preferably, the rotating module includes a rotating base fixedly connected to the bracket, a rotating body movably connected to the rotating base, and a plurality of limiting components disposed between the rotating base and the rotating body.

[0009] Preferably, in a plurality of the nozzle assemblies, one nozzle assembly includes a second nozzle tube connected to the rotating body, a beam splitter disposed in the inner cavity of the second nozzle tube, a plurality of reflectors located in the outer edge direction of the beam splitter, and a second feed tube mounted on the second nozzle tube. The outlet of the second feed tube is disposed inside the nozzle opening of the second nozzle tube and is coaxially arranged with the nozzle opening of the second nozzle tube.

[0010] Preferably, the second nozzle tube has a plurality of reflective light path through holes, and the plurality of reflective light path through holes correspond one-to-one with the plurality of reflectors.

[0011] Preferably, in the plurality of nozzle assemblies, one nozzle assembly includes a third nozzle tube connected to the rotating body, a reflective focusing mirror disposed in the inner cavity of the third nozzle tube, and a plurality of third feed tubes mounted on the third nozzle tube, wherein the outlets of the plurality of third feed tubes are equidistantly arranged along the outer circumferential direction of the nozzle opening of the third nozzle tube.

[0012] Preferably, the surface of the rotating base is provided with a rotating cavity, the rotating body is disposed in the rotating cavity, and the inner wall of the rotating cavity is provided with a plurality of limiting holes along the circumferential direction, the limiting holes being used to cooperate with the ball head of the limiting component.

The fixed through hole corresponds to the emission end of the collimator device, and a fixed convex lens is provided between the fixed through hole and the emission end of the collimator device.

[0014] Preferably, the surface of the rotating body is provided with a plurality of through holes distributed along the circumferential direction, and the plurality of through holes correspond one-to-one with one end of a plurality of nozzle assemblies.

[0015] By adopting the above technical solution, the beneficial effects achieved by the present invention are as follows: In this invention, multiple nozzles for different application conditions are integrated through a rotating module, and a collaborative working mechanism is constructed. This enables rapid switching of nozzles for different working conditions without the need for repeated disassembly and assembly, significantly improving work efficiency. Simultaneously, it supports multiple nozzles with different structures sharing a single collimator device, effectively reducing nozzle configuration costs and improving equipment cost-effectiveness. Furthermore, the flexible switching of different nozzles not only meets the forming requirements of complex parts but also satisfies the needs of large-scale, multi-condition alternating industrial production, providing an efficient solution for diverse production demands.

[0034] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described below in conjunction with the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0035] Numerous specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways than those described herein, and therefore the invention is not limited to the specific embodiments disclosed in the following specification.

[0036] like Figures 1-17 As shown, this invention provides a multi-condition collaborative integrated laser cladding metal additive manufacturing equipment, including a support 1 for connecting to a robotic arm, a collimator device 2 mounted on the support 1 and connected to a laser head, and a rotating module 3 for driving the rotation of multiple nozzle assemblies 4 and connected to the support 1. Multiple nozzle assemblies 4 are fixedly mounted on the rotating module 3. Through the rotation of the rotating module 3, the nozzles 400 of the multiple nozzle assemblies 4 can be coaxially aligned with the beam emitted from the collimator device 2. This document describes three nozzle assemblies 4; thus, through the rotation of the rotating module 3, the nozzles 400 of the three nozzle assemblies 4 can be coaxially aligned with the beam emitted from the collimator device 2 one by one.

[0037] Combination Figure 2 , Figure 3 and Figure 4 As shown, as a further step, the rotating module 3 includes a rotating base 31 fixedly connected to the bracket 1, a rotating body 32 movably connected to the rotating base 31, and a plurality of limiting components 33 disposed between the rotating base 31 and the rotating body 32. The plurality of limiting components 33 are equidistantly distributed along the circumferential direction of the rotating body 32, and the rotating body 32 forms a multi-point cooperative limiting with the rotating base 31 through the plurality of limiting components 33, so as to ensure the stability of the position after the two are connected.

[0038] Specifically, the limiting component 33 is a ball-head spring plunger composed of a base component 331, a spring component 332, and a ball-head component 333. The base component 331 is connected to the circumferential direction of the rotating body 32. A rotating cavity 5 is opened on the surface of the rotating base 31. The rotating body 32 is disposed in the rotating cavity 5. A plurality of limiting holes 6 are opened on the inner wall of the rotating cavity 5 along the circumferential direction. The limiting holes 6 are used to cooperate with the ball-head component 333 of the limiting component 33.

[0039] By cooperating with the ball-head spring plunger and the limiting hole 6, the rotating body 32 can easily switch between multiple nozzle assemblies 4 when rotating in the rotating cavity 5, and ensure the stability of the nozzle assembly 4 after switching. Therefore, this rotation adjustment method allows multiple nozzle assemblies 4 to share a collimator device 2 for different working conditions, thereby effectively reducing the cost of laser cladding metal additive manufacturing equipment and making it more cost-effective.

[0040] As a further step, the inner wall of the rotating cavity 5 is provided with a fixed through hole 7 that passes through the rotating base 31. The fixed through hole 7 corresponds to the output end of the collimator device 2, and a fixed convex lens 9 is provided between the fixed through hole 7 and the output end of the collimator device 2. The function of the fixed convex lens 9 is to convert the diverging beam into a parallel beam.

[0041] Furthermore, the surface of the rotating body 32 is provided with multiple circumferentially distributed movable through holes 8, each corresponding to one end of a plurality of nozzle assemblies 4. The dimensions of the multiple movable through holes 8 are the same as those of the fixed through holes 7. By utilizing the one-to-one correspondence between the multiple movable through holes 8 and the multiple nozzle assemblies 4, the light beam emitted from the collimator device 2, after passing through the fixed through holes 7, can be transmitted to the corresponding movable through holes 8 under the rotation of the rotating module 3. The parallel light beam entering the movable through holes 8 can then be focused at the nozzle orifice 400 of each nozzle assembly 4 to form a high-energy-density light spot, thereby achieving the cladding effect.

[0042] It is worth noting that the definitions of fixed through hole 7 and movable through hole 8 in this article are as follows: a through hole that is in one fixed position is a fixed through hole 7; while a through hole that is in a position that can change is a movable through hole 8.

[0043] As a further step, when described with three nozzle assemblies 4, one of the nozzle assembly 4 includes a first nozzle tube 410 connected to the rotating body 32, a movable convex lens 411 disposed in the inner cavity of the first nozzle tube 410, and a first feed tube 412 mounted on the first nozzle tube 410, with the outlet of the first feed tube 412 located outside the nozzle port 400 of the first nozzle tube 410. Another nozzle assembly 4 includes a second nozzle tube 420 connected to the rotating body 32, a beam splitter 421 disposed in the inner cavity of the second nozzle tube 420, a plurality of reflectors 422 located on the outer edge of the beam splitter 421, and a second feed tube 423 mounted on the second nozzle tube 420. The outlet of the second feed tube 423 is disposed inside the nozzle opening 400 of the second nozzle tube 420 and is coaxially arranged with the nozzle opening 400 of the second nozzle tube 420. A plurality of reflective light path through holes 424 are provided on the second nozzle tube 420, and the plurality of reflective light path through holes 424 correspond one-to-one with the plurality of reflectors 422. The last nozzle assembly 4 includes a third nozzle tube 430 connected to the rotating body 32, a reflective focusing mirror 431 disposed in the inner cavity of the third nozzle tube 430, and a plurality of third feed tubes 432 mounted on the third nozzle tube 430, wherein the outlets of the plurality of third feed tubes 432 are equidistantly arranged along the outer circumferential direction of the nozzle opening 400 of the third nozzle tube 430. Example

[0044] Combination Figure 5 , Figure 11 and Figure 12As shown, the nozzle assembly 4 includes a first nozzle tube 410 connected to the rotating body 32, a movable convex lens 411 disposed in the inner cavity of the first nozzle tube 410, and a first feed tube 412 mounted on the first nozzle tube 410. The outlet of the first feed tube 412 is located outside the nozzle port 400 of the first nozzle tube 410. The first feed tube 412 is a lateral feed tube, which facilitates the conveying of cladding material to the molten pool area. In this embodiment, the nozzle assembly 4 can be defined as a lateral powder feeding nozzle.

[0045] For the machining and forming of deep-cavity parts, due to the narrow machining space, a side-feeding powder nozzle can be used for cladding, effectively adapting to the machining requirements of confined spaces. The specific operation is as follows: First, the rotating body 32 rotates within the rotating cavity 5, causing the spring 332 and the ball head 333 to fix the rotated body 32 again, so that a moving through hole 8 corresponds to a fixed through hole 7, that is, the side powder feeding nozzle corresponds to the collimator device 2. Then, the collimator device 2 is connected to the laser head. After the laser is emitted from the laser head, the laser beam can pass through the collimator device 2, the fixed convex lens 9 and the moving convex lens 411 in sequence. The fixed convex lens 9 is used to convert the diverging beam into a parallel beam for transmission. After the parallel beam is transmitted to the inside of the first nozzle tube 410, the moving convex lens 411 can focus the parallel beam at the nozzle opening 400 of the first nozzle tube 410 to form a high-energy-density light spot. During this period, the first feeding tube 412 can transport the cladding material to the molten pool area, thereby cooperating with the high-energy light spot to carry out the cladding work.

[0046] It is worth noting that the definitions of fixed convex lens 9 and movable convex lens 411 in this paper are as follows: a convex lens that is in a fixed position is a fixed convex lens 9; while a convex lens that is capable of changing position is a movable convex lens 411. Example

[0047] Combination Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 13 , Figure 14 , Figure 15 and Figure 16As shown, the nozzle assembly 4 includes a second nozzle tube 420 connected to the rotating body 32, a beam splitter 421 disposed within the cavity of the second nozzle tube 420, a plurality of reflectors 422 located along the outer edge of the beam splitter 421, and a second feed tube 423 mounted on the second nozzle tube 420. The outlet of the second feed tube 423 is located inside the nozzle opening 400 of the second nozzle tube 420 and is coaxially arranged with the nozzle opening 400 of the second nozzle tube 420. A plurality of reflective light path through holes 424 are provided on the second nozzle tube 420, and each of the plurality of reflective light path through holes 424 corresponds one-to-one with a plurality of reflectors 422. Figure 8 As shown, the second feed pipe 423 is located inside the second nozzle pipe 420. It is used to transport the cladding material to the molten pool area through the nozzle opening 400. In this embodiment, the nozzle assembly 4 can be defined as a multi-beam nozzle.

[0048] It should be noted that in this embodiment, the beam splitter 421 can be a multi-prism. This article takes a triangular prism as an example. In this case, three reflectors 422 are respectively provided and are equidistant from the beam splitter 421 along the circumferential direction. At the same time, the three reflectors 422 correspond one-to-one with the three beam splitting surfaces on the beam splitter 421. In addition, a protective lens is provided in each reflected light path through hole 424. The protective lens is made of light-transmitting material. The light-transmitting protective lens can not only ensure the normal transmission of laser light, but also prevent dust from entering.

[0049] For parts with high shape accuracy requirements (such as three-dimensional molded parts), a multi-beam nozzle can be used for cladding to improve forming accuracy. The specific operation is as follows: First, the rotating body 32 rotates within the rotating cavity 5, causing the spring 332 and the ball head 333 to fix the rotated body 32 again, so that a moving through hole 8 corresponds to a fixed through hole 7. Then, the collimator device 2 is connected to the laser head. After the laser is emitted from the laser head, the laser beam can be collimated by the fixed convex lens 9 (converting the divergent beam into a parallel beam). Subsequently, the parallel beam enters the second nozzle tube 420 and is refracted by the beam splitter on the beam splitter 421 onto the corresponding reflector 422. Finally, through the action of the reflector 422, the beam can be reflected to the nozzle opening 400 of the second nozzle tube 420 for convergence, forming a high-energy-density light spot. During this process, the second feed tube 423 can transport the cladding material to the molten pool area, thereby cooperating with the high-energy light spot to carry out the cladding work. Example

[0050] Combination Figure 10 and Figure 17As shown, the nozzle assembly 4 includes a third nozzle tube 430 connected to the rotating body 32, a reflecting focusing mirror 431 disposed in the inner cavity of the third nozzle tube 430, and a plurality of third feed tubes 432 mounted on the third nozzle tube 430. The outlets of the plurality of third feed tubes 432 are equidistantly arranged along the outer circumferential direction of the nozzle opening 400 of the third nozzle tube 430. The plurality of third feed tubes 432 are used for simultaneous conveying of cladding material to ensure that the processed material is conveyed to the molten pool area; and the nozzle assembly 4 in this embodiment can be defined as an extended long tube nozzle.

[0051] For machining the inner walls of shaft-type parts, which are often quite long and difficult to reach with traditional cladding nozzles, the extended long-tube nozzle used in this example can be employed for cladding, making it easier to meet the machining requirements of the inner walls. The specific operation is as follows: First, the rotating body 32 rotates within the rotating cavity 5, causing the spring 332 and the ball head 333 to fix the rotated body 32 again, so that a moving through hole 8 corresponds to a fixed through hole 7, that is, the extended long tube nozzle corresponds to the collimator device 2. Then, the collimator device 2 is connected to the laser head. After the laser is emitted from the laser head, the laser beam can be collimated by the fixed convex lens 9 to convert the divergent beam into a parallel beam. Then, the parallel beam enters the third nozzle tube 430 and can be transmitted to the reflecting focusing mirror 431. The reflecting focusing mirror 431 can reflect and focus the parallel beam onto the nozzle opening 400 of the third nozzle tube 430 to form a high-energy-density light spot. During this period, multiple third feeding tubes 432 can transport the cladding material to the molten pool area, thereby cooperating with the high-energy light spot to carry out the cladding work.

[0052] In summary, this invention achieves rapid knob-style switching by integrating the nozzle rotation module 3, completely solving the problem of complex and time-consuming nozzle replacement procedures in traditional nozzles according to working conditions, and significantly improving work efficiency; at the same time, it reduces the capital investment and subsequent maintenance costs of key parts (collimator device 2) in the nozzle.

[0053] Furthermore, this invention integrates multiple nozzles for different application conditions into a single unit through the rotating module 3, which allows them to work together collaboratively. Its advantages are as follows: 1. It enables quick switching of nozzles for different application conditions without the need for repeated disassembly and assembly, resulting in high work efficiency.

[0054] 2. It enables multiple nozzles with different structures to use a single collimator device, effectively reducing nozzle configuration costs and offering better cost performance.

[0055] 3. When cladding and forming complex parts, such as parts with features such as deep cavities, long inner shafts, and complex structures, this invention can meet the forming requirements of complex parts by switching different nozzles, and can also meet the needs of large-scale industrial production with multiple working conditions.
