Description

Technical Field

[0001] This utility model relates to the field of 3D printing, and in particular to an integrated laser-assisted enhancement device. Background Technology

[0002] 3D printing typically uses a laser cladding head to melt the corresponding material. Since the laser cladding head outputs a fixed, continuous power, its penetration is poor when encountering materials with high reflectivity during the actual cladding process. Therefore, the surface of the molten material often exhibits phenomena such as pinholes, resulting in lower product quality. Thus, how to ensure the material melts completely to reduce pinholes in the finished product has become one of the urgent problems that technicians need to solve. Utility Model Content

[0003] In order to overcome the shortcomings of the existing technology, this utility model provides an integrated laser-assisted enhancement device.

[0004] This utility model is achieved using the following technical solution: an integrated laser-assisted enhancement device, comprising a mounting platform, a main laser head, and an auxiliary laser head. The mounting platform is provided with a main mounting hole and an auxiliary mounting hole. The main laser head is fixed in the main mounting hole by a snap-fit ​​component. The auxiliary laser head is detachably fixed in the auxiliary mounting hole by a snap-fit ​​component. The main laser head is positioned above the workpiece, and the auxiliary laser head is positioned to one side of the main laser head and is tilted towards the main laser head.

[0005] The mounting platform has a limiting slot, which is arranged along the length of the mounting platform. At least one pair of mounting blocks are provided in the limiting slot. The main mounting hole and the auxiliary mounting hole are respectively opened on a mounting block. The mounting block slides in the limiting slot. A fixing member is provided between the limiting slot and the mounting block to fix the position of the mounting block.

[0006] The fastener includes an abutment block, and an abutment hole is formed on the side wall of the limiting slot along the length direction of the limiting slot. The abutment block is disposed in the abutment hole and extends out of the abutment hole to abut against the mounting block.

[0007] A limiting groove is provided on the side wall of the mounting block, and the abutment block is inserted into the limiting groove when it extends.

[0008] The cross-section of the abutment block is T-shaped. The vertical part of the abutment block passes through the abutment hole and abuts against the abutment block. The two ends of the horizontal part of the abutment block extend into the abutment hole towards the edge of the mounting platform and pass through the mounting platform. The mounting platform is provided with abutting bolts for abutting against the abutment block.

[0009] The side wall of the mounting platform is recessed inward to form a receiving groove. The abutment block protrudes from the bottom of the receiving groove. A threaded hole is opened on the side wall of the receiving groove. The tightening bolt protrudes from the threaded hole and abuts against the abutment block.

[0010] The tightening bolt includes a stud, a rotating knob is fixed in the middle of the stud, one end of the stud is inserted into the threaded hole and threadedly engaged with the threaded hole, and the other end of the stud abuts against the abutting block.

[0011] The snap-fit ​​component includes elastic posts. Both the main laser head and the auxiliary laser head have a plurality of elastic posts on their outer shells. When the main laser head is inserted into the main mounting hole, the elastic posts abut against the side wall of the main mounting hole. When the auxiliary laser head is inserted into the auxiliary mounting hole, the elastic posts abut against the inner wall of the auxiliary mounting hole.

[0012] Compared to existing technologies, this invention utilizes a main laser head and an auxiliary laser head to work on the same location of the material during operation. The main laser head continuously applies energy, while the auxiliary laser head operates intermittently. The auxiliary laser head is a pulsed laser head, emitting light intermittently. After the main laser head melts the material, it intermittently releases energy at the same location, resulting in localized graining of the material and improving the material properties in 3D printing. Simultaneously, through pulse modulation, the auxiliary laser head can release energy rapidly, reaching high power at the peak. However, due to the presence of troughs (low energy points) during pulse release, the average power of the auxiliary laser head is relatively low. Therefore, in actual use, the instantaneous power of the auxiliary laser head can be significantly greater than that of the main laser head, resulting in greater penetration depth during material processing. This makes it suitable for processing materials with high surface reflectivity. Attached Figure Description

[0014] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0015] Reference Figs. 1-3 An integrated laser-assisted enhancement device includes a mounting platform 1, a main laser head 2, and an auxiliary laser head 3. The mounting platform 1 has a main mounting hole 12 and an auxiliary mounting hole 13. The main laser head 2 is fixed in the main mounting hole 12 by a snap-fit ​​component 5, and the auxiliary laser head 3 is detachably fixed in the auxiliary mounting hole 13 by the snap-fit ​​component 5. The main laser head 2 is positioned above the workpiece, and the auxiliary laser head 3 is positioned to one side of the main laser head 2 and tilted towards it. The main laser head 2 continuously outputs light, serving as the primary cladding head. The auxiliary laser head 3 serves as an auxiliary component. During operation, both the main laser head 2 and the auxiliary laser head 3 work on the same location of the material. The main laser head 2 continuously outputs light, while the auxiliary laser head 3 outputs light intermittently. The auxiliary laser head 3 is a pulsed laser head, emitting light intermittently. After the main laser head 2 clads the material, it intermittently releases energy at the same location on the material, thereby causing localized graining of the material and improving the material properties of 3D printing. Simultaneously, through pulse modulation, the auxiliary laser head 3 can release rapidly, thereby reaching several high powers at the peak position. However, due to the presence of troughs during pulse release, i.e. low energy points, the average power of the auxiliary laser head 3 is relatively low. In actual use, the instantaneous power of the auxiliary laser head 3 can be much greater than that of the main laser head 2, resulting in greater penetration depth during material processing. This makes it suitable for processing materials with high surface reflectivity.

[0016] In this embodiment, to facilitate faster laser head replacement, a limiting slot 46 is provided on the mounting platform 1. The limiting slot 46 is arranged along the length of the mounting platform 1, and at least one pair of mounting blocks 11 are provided within the limiting slot 46. The main mounting hole 12 and the auxiliary mounting hole 13 are respectively provided on one mounting block 11. The mounting block 11 slides within the limiting slot 46, and a fixing member 4 is provided between the limiting slot 46 and the mounting block 11 to fix the position of the mounting block 11. The main laser head 2 and the auxiliary laser head 3 are respectively mounted on different mounting blocks 11, and the mounting blocks 11 can move within the limiting slot 46, allowing the positions of the main laser head 2 and the auxiliary laser head 3 to be flexibly adjusted to handle the processing of materials of different shapes. When the mounting block 11 is moved into place, its position can be fixed by the fixing member 4, thus fixing the positions of the main laser head 2 and the auxiliary laser head 3 throughout the processing, achieving better processing.

[0017] In this embodiment, the fixing member 4 includes an abutment block 41. An abutment hole 42 is formed on the side wall of the limiting slot 46 along the length direction of the limiting slot 46. The abutment block 41 is disposed in the abutment hole 42 and extends out of the abutment hole 42 to abut against the mounting block 11. A limiting groove is formed on the side wall of the mounting block 11. When the abutment block 41 extends out, it is inserted into the limiting groove. The cross-section of the abutment block 41 is T-shaped. The vertical part of the abutment block 41 extends out of the abutment hole 42 and abuts against the mounting block 1. The two ends of the horizontal part of the abutment block 41 extend into the edge of the mounting platform 1 within the abutment hole 42 and extend out of the mounting platform 1. The mounting platform 1 is provided with a clamping bolt 43 for clamping against the abutment block 41. Specifically, the side wall of the mounting platform 1 is recessed inward to form a receiving groove. The abutment block 41 extends out from the bottom of the receiving groove. A threaded hole 44 is formed on the side wall of the receiving groove. The clamping bolt 43 passes through the threaded hole 44 and abuts against the abutment block 41.

[0018] In this embodiment, the clamping bolt 43 needs to be specially made. Specifically, the clamping bolt 43 includes a stud, with a rotating knob 45 fixed in the middle of the stud. One end of the stud is inserted into the threaded hole 44 and engages with the threaded hole 44, while the other end of the stud abuts against the abutting block 41. When rotated, the upper part of the stud extends out of the threaded hole 44, thereby abutting against the abutting block 41 and pushing the abutting block 41 against the mounting block 11, thus fixing the position of the mounting block 11 during use.

[0019] In this embodiment, to achieve quick-release assembly of the main laser head 2 and the auxiliary laser head 3, a snap-fit ​​component 5 needs to be installed on the outer shell of the main laser head 2 and the auxiliary laser head 3. Specifically, the snap-fit ​​component 5 may include elastic posts 51. Both the outer shell of the main laser head 2 and the auxiliary laser head 3 are provided with several elastic posts 51. When the main laser head 2 is inserted into the main mounting hole 12, the elastic posts 51 abut against the side wall of the main mounting hole 12. When the auxiliary laser head 3 is inserted into the auxiliary mounting hole 13, the elastic posts 51 abut against the inner wall of the auxiliary mounting hole 13. Annular grooves 52 can be formed on the inner walls of the main and auxiliary mounting holes 13. The upper circumference of the annular groove 52 can form a smooth transition surface, allowing the mounting component to be easily pulled out of the annular groove 52, thus facilitating disassembly and assembly.

[0020] Compared to existing technologies, this invention utilizes a main laser head 2 and an auxiliary laser head 3 to perform work on the same location of the material during operation. The main laser head 2 continuously applies energy, while the auxiliary laser head 3 operates intermittently. The auxiliary laser head 3 is a pulsed laser head, emitting light intermittently. After the main laser head 2 melts the material, it intermittently releases energy at the same location, resulting in localized graining of the material and improving the material properties in 3D printing. Simultaneously, through pulse modulation, the auxiliary laser head 3 can release energy rapidly, reaching high power at the peak. However, due to the presence of troughs (low energy points) during pulse release, the average power of the auxiliary laser head 3 is relatively low. Therefore, in actual use, the instantaneous power of the auxiliary laser head 3 can be significantly greater than that of the main laser head 2, resulting in greater penetration depth during material processing. This makes it suitable for processing materials with high surface reflectivity.

Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
