It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.
[0032] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings.
[0033] Please see Figures 1-6 As shown, an adjusting device includes:
[0034] Fiber optic assembly 100, used for mounting fiber optic cables;
[0035] The light-emitting component 200 is connected to the optical fiber component 100, and the light-emitting component 200 is provided with a collimating lens 1 and a focusing lens 2;
[0036] The beam splitter 300 is connected to the light output component 200, and a prism 3 is disposed inside the beam splitter 300.
[0037] The light-emitting component 200 or the beam-splitting component 300 is further provided with an adjustment component 400, which is used to adjust the relative position of the light-emitting component 200 and the beam-splitting component 300 so that the prism 3 is coaxially arranged with the optical fiber, the collimating lens 1 and the focusing lens 2.
[0038] The adjustment component 400 makes the prism 3 coaxial with the optical fiber, the collimating lens 1 and the focusing lens 2, reducing the coaxial error between the prism 3 and the light-emitting component 200, and improving the cladding quality. This not only improves the uniformity density of the optical path welding energy and ensures a high-quality cladding effect, but also improves the welding effect and work efficiency.
[0039] Furthermore, the adjustment component 400 includes an adjustment element 4, a first adjustment block, and at least one second adjustment block 42. The first and second adjustment blocks 42 are disposed on the beam splitting component 300, and each of the first and second adjustment blocks 42 is provided with at least one adjustment element 4. By setting the first adjustment block and at least one second adjustment block 42, the adjustment element 4 can be used to adjust the light-emitting component 200 along the X-axis and / or Y-axis, thereby making the prism 3 coaxial with the optical fiber, the collimating lens 1, and the focusing lens 2, reducing the coaxial error between the prism 3 and the light-emitting component 200, and avoiding the problem of poor cladding quality caused by this. This not only improves the uniformity density of the optical path welding energy and ensures a high-quality cladding effect, but also improves the welding effect and increases work efficiency.
[0040] Furthermore, the adjusting component 4 is configured as a ball screw. The ball screw not only facilitates adjustment of the light-emitting assembly 200 but also prevents damage to the light-emitting assembly 200, resulting in a simple structure and improved work efficiency.
[0041] Furthermore, the adjustment device also includes a third adjustment block 43 and a fixing plate 5. At least one adjustment member 4 is provided on the fixing plate 5. The adjustment member 4 adjusts the position of the light-emitting component 200 relative to the beam-splitting component 300 via the fixing plate 5. When the adjustment member 4 is turned, it pushes the third adjustment block 43 to move, causing the third adjustment block 43 to adjust the light-emitting component 200 along the X-axis or Y-axis. This makes the prism 3 coaxial with the optical fiber, the collimating lens 1, and the focusing lens 2, reducing the coaxial error between the prism 3 and the light-emitting component 200, and avoiding the resulting problem of poor cladding quality. This not only improves the uniformity density of the optical path welding energy and ensures a high-quality cladding effect, but also enhances the welding effect and improves work efficiency.
[0042] Furthermore, the first adjustment block 41 is provided with a first slot 411, the third adjustment block 43 is provided with a second slot 431, and the light-emitting component 200 is provided with a locking protrusion 201 that is respectively locked in the first slot 411 and the second slot 431. The first slot 411 and the second slot 431 cooperate with the locking protrusion 201 to guide and limit the light-emitting component 200, which facilitates the adjustment of the light-emitting component 200 and is beneficial to the adjustment of the light-emitting component 200 by the adjustment member 4, so that the prism 3 can quickly become coaxial with the optical fiber, the collimating lens 1 and the focusing lens 2.
[0043] Furthermore, the width of the protrusion 201 is smaller than the width of the first slot 411 or the second slot 431, so that the protrusion 201 can slide within the first slot 411 or the second slot 431 for easy adjustment.
[0044] Furthermore, the fixing plate 5 is also provided with a locking member 51 for locking the light-emitting component 200. After adjustment, the locking member 51 and the fixing plate 5 can be used to lock the light-emitting component 200 to prevent it from moving during use, ensuring that the prism 3 is coaxial with the optical fiber, the collimating lens 1 and the focusing lens 2, ensuring a high-quality cladding effect, improving the welding effect and increasing work efficiency.
[0045] Furthermore, the locking element 51 is configured as an adjusting screw. The adjusting screw not only allows for convenient adjustment of the light-emitting assembly 200, but also prevents damage to the light-emitting assembly 200, resulting in a simple structure and improved work efficiency.
[0046] Furthermore, a sealing element 6 is provided inside the beam splitter 300, and the beam splitter 300 is sealed to the light emitting element 200 through the sealing element 6. This prevents dust from entering the beam splitter 300 and the light emitting element 200 during the adjustment process, and ensures that no frictional powder is generated during the adjustment process to contaminate the focusing lens 2 and the prism 3.
[0047] Furthermore, the light-emitting assembly 200 also includes a first fixing base 7, within which a first retaining ring 71 for fixing the collimating lens 1 is provided, and a second retaining ring 72 for fixing the focusing lens 2 is also provided. The first retaining ring 71 can fix the collimating lens 1 to prevent its displacement, and the second retaining ring 72 can fix the focusing lens 2 to prevent its displacement, ensuring the relative positions of the collimating lens 1 and the focusing lens 2 within the light-emitting assembly 200, ensuring that the optical fiber, the collimating lens 1, and the focusing lens 2 are coaxially arranged, reducing the coaxial error between the prism 3 and the light-emitting assembly 200, and avoiding the problem of poor cladding quality caused by this. This not only improves the uniformity density of the optical path welding energy and ensures a high-quality cladding effect, but also improves the welding effect and increases work efficiency.
[0048] Furthermore, the beam splitting assembly 300 includes a second fixing base 8, within which a partition 81 for fixing the prism 3 is disposed. The partition 81 can fix the prism 3, prevent its displacement, and ensure the relative position of the prism 3 within the beam splitting assembly 300. When the light-emitting assembly 200 is adjusted by the adjusting member 4, it facilitates the coaxiality of the prism 3 with the optical fiber, the collimating lens 1, and the focusing lens 2.
[0049] Based on the aforementioned adjustment device, this application embodiment also provides a laser cladding device, including a wire feeding assembly 500, a nozzle 600, and the adjustment device, wherein the nozzle 600 is connected to the wire feeding assembly 500. Through the adjustment action of the adjustment assembly 400, the prism 3 is made coaxial with the optical fiber, the collimating lens 1, and the focusing lens 2, reducing the coaxial error between the prism 3 and the light-emitting assembly 200, thus avoiding the problem of poor cladding quality caused by this error. This not only improves the uniformity density of welding energy in the optical path but also enhances the welding effect and increases work efficiency.
[0050] Furthermore, the beam splitter 300 is provided with multiple light outlets 301, and the beam splitter 300 is also provided with multiple reflectors 9 corresponding to the light outlets 301. The prism 3 splits the laser emitted from the optical fiber into multiple beams 90. The multiple beams 90 are reflected by their corresponding reflectors 9 and irradiate the nozzle 600. When the wire feeding assembly 500 feeds the welding wire 91 to the nozzle 600, the multiple reflectors 9 irradiate the welding wire 91 at the nozzle 600 with the multiple beams of the welding wire 91, uniformly heating multiple surfaces of the welding wire 91, improving the uniformity density of the welding energy in the optical path, thereby improving the quality of 3D wire feeding and ensuring a high-quality cladding effect.
[0051] Furthermore, the light outlet 301 is provided with three, and the reflector 9 is also provided with three corresponding beams. The three beams simultaneously irradiate the welding wire 91, uniformly heating the three surfaces of the welding wire 91, improving the uniformity and density of the welding energy in the optical path, thereby improving the quality of 3D wire feeding and ensuring a high-quality cladding effect.
[0052] Furthermore, a detection device for detecting the beam energy of the emitted light 90 can be provided at the light outlet 301, the nozzle 600, or the reflector 9. Three detection devices are provided corresponding to the emitted light 90, and each of the three detection devices detects one of the three emitted light beams 90. When the beam energy of the three emitted light beams 90 is equal, it can be known that the prism 3 is coaxial with the optical fiber, the collimating lens 1, and the focusing lens 2. Due to the coaxial arrangement, the prism 3 splits the laser emitted from the optical fiber into three emitted light beams 90. When the energy of the three emitted light beams 90 is equal... If the beam energies are not equal, it indicates that the prism 3 is not coaxial with the optical fiber, the collimating lens 1, and the focusing lens 2. In this case, the light-emitting assembly 200 can be adjusted along the X-axis and / or Y-axis by rotating the adjusting member 4 until the beam energies of the three emitted beams 90 are equal. The adjustment is then complete. Subsequently, the locking member and fixing plate 5 can be used to lock the light-emitting assembly 200 to prevent it from moving during use, ensuring that the prism 3 is coaxial with the optical fiber, the collimating lens 1, and the focusing lens 2. This ensures a high-quality cladding effect, improves welding efficiency, and increases work efficiency.
