Description

Technical Field

[0001] This invention relates to the interdisciplinary field of optical engineering, geotechnical engineering, and mechanical engineering, and to a laser cutting head and its assembly and adjustment method, particularly to a cutting head mounting base capable of obtaining distributed laser light based on a traditional laser cutting head and its assembly and adjustment method. Background Technology

[0002] Currently, laser rock breaking technology is mainly used in the extraction of mineral energy such as oil and natural gas. In the future, optimizing and improving laser cutting machines, enhancing the rock-breaking effect of laser rock breaking technology, and further coupling laser rock breaking technology into large-scale rock-cutting equipment such as TBMs (tunnel boring machines), roadheaders, drilling rigs, and open-pit mining machines (hereinafter referred to as cutting equipment) is an inevitable development trend.

[0003] Existing laser cutting machines emit a straight circular laser (hereinafter referred to as a conventional laser) through their laser cutting head (hereinafter referred to as a conventional laser). Due to the excessively concentrated power density of conventional lasers, a large amount of rock is melted into lava or even vaporized in a short period of time; a small portion of the lava is promptly blown out of the laser groove, while the majority adheres to the laser groove wall, which solidifies into a smooth glassy coating layer (hereinafter referred to as glass glaze) after cooling. Studies have shown that the presence of glass glaze leads to the following limitations in conventional laser rock breaking: 1) As the laser power increases, the laser energy efficiency and rock breaking effect no longer increase significantly. This is because the large amount of glass glaze produced not only reduces the macroscopic rock breaking effect of the laser (such as the width and depth of the groove) but also inhibits the transmission of laser energy to deeper rock layers; 2) Glass glaze acts like an adhesive, continuously bonding existing rock cracks, thus hindering the extension and convergence of macroscopic and microscopic cracks, reducing the rock breaking effect. Researchers have attempted to suppress the formation of glass glaze by addressing issues such as laser irradiation modes, cooling techniques, and surface pretreatment. However, since the wavefront shape and highly focused optical characteristics of traditional lasers have not been fundamentally altered, the results have been minimal.

[0004] To address the shortcomings of existing laser cutting machines, developing a completely new laser cutting machine from the ground up, starting with the underlying components, presents limitations such as high risk, significant difficulty, high cost, and a long development cycle. Especially when coupling laser rock-breaking technology to large-scale rock-cutting equipment, the research is in its early feasibility verification stage, and developing a high-power, full-size new laser cutting machine clearly carries enormous development risks. How to quickly and economically prepare a new laser that effectively suppresses glass glaze formation based on traditional laser equipment, especially without changing the main body of the existing laser cutting machine, using a traditional laser cutting head, in order to rapidly conduct feasibility verification experiments, is a problem that researchers in this field urgently need to solve.

It should be noted that, unless otherwise specified, the embodiments and features of the present invention can be combined with each other.

The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

"Above," "below," "underneath," "left," "right," etc., are only used to indicate relative positional relationships, and when the absolute position of the described object changes, the relative positional relationship also changes accordingly.

[0045] like Figures 1 to 12 All figures in this invention are attached.

[0046] Before introducing this invention, it is necessary to use the E1039M laser cutting machine as an example to explain the beam shaping principle of traditional lasers. In the main unit of this type of laser cutting machine, an initial beam (not shown) is first generated by a CO2 laser generator (not shown), which sequentially passes through a light guide tube (not shown) and a bellows tube (not shown) to output a stable beam (not shown); subsequently, the stable beam is guided sequentially through a phase shifter (not shown) and a reflector (not shown), and then passes through a focusing lens (not shown) to generate a beam as shown in the diagram. Figure 12 The preliminary focused beam (10) is shown; as shown Figures 1 to 4 As shown, the conventional laser cutting head (1) is mounted on the three-axis traveling mechanism (also known as the moving crossbeam, not shown) of the laser cutting machine, and a convex lens (5) is embedded in the conventional laser cutting head (1); Figure 4 and Figure 12 As shown, the initially focused beam (7) enters the convex lens (5) inside the conventional laser cutting head (1) via the transmission fiber (not shown), and finally emits a conventional laser with a diameter of d4; this conventional laser is emitted through the outlet (not numbered) of the conventional laser cutting head (1) and forms a circular spot with an outer diameter of d4 on the surface of the rock (11); studies have shown that the power density distribution within the circular spot area is highly concentrated. Figures 5 to 7 As shown, more specifically, the convex lens (5) of the E1039M laser cutting machine can be a spherical plano-convex lens with an outer diameter d1 of 25.4 mm, a lens thickness T1 of 4.3 mm, and a spherical curvature SR of 70 mm. Specific Implementation Example 1:

[0048] To ensure rock-breaking efficiency while cost-effectively and efficiently preparing a novel laser that can effectively suppress glass glaze formation, and to rapidly conduct feasibility verification experiments, such as 1 to... Figure 11 As shown, the present invention provides a cutting head mounting base capable of obtaining distributed laser light, characterized in that:

[0049] Includes mounting bracket (3), frame assembly (4), and optical lens group (unnumbered), wherein:

[0050] The frame assembly (4) includes a frame (41); the optical lens group includes an aperture concave lens (6); such as Figures 9 to 11 As shown, the concave lens (6) has a through hole with a diameter of d2 at its center; d2 is smaller than the diameter d4 of the conventional laser emitted from the conventional laser cutting head (1); as Figure 8 As shown, the frame (41) has a mounting through hole at its center, and an open concave lens (6) is installed inside it; the frame assembly (4) is installed inside the mounting bracket (3); the mounting bracket (3) is detachably and securely mounted on the conventional laser cutting head (1); as Figure 12 As shown, the concave lens (6) with an opening is located directly below the outlet of the conventional laser cutting head (1), and the concave lens (6) and the convex lens (5) are separated by a certain distance l1 (i.e., lens distance) and are arranged coaxially. At the same time, the concave lens (6) with an opening is separated from the rock surface by a certain distance l2 (i.e., object distance).

[0051] Studies have shown that conventional laser beams with a diameter not greater than d2 can directly pass through the through-hole of the concave lens (6). According to the principle of light propagation, the power density distribution characteristics of the beam that directly passes through the through-hole remain unchanged, that is, it is still a conventional laser. The high-focusing energy density of conventional lasers can be used to quickly prepare laser grooving. The conventional laser beam will form a circular spot with an outer diameter of d2 on the surface of the rock irradiated by the laser. The remaining part of the conventional laser beam with a diameter greater than d2 is refracted by the solid area of ​​the concave lens to generate a cone-shaped refracted beam, which will form an annular spot with an outer diameter of d5 on the surface of the rock irradiated by the laser. The power density in the circular spot with an outer diameter of d2 is highly concentrated, while the power density in the annular spot area decreases with the increase of the radial direction (that is, the distance between any point and the center of the optical lens group). Therefore, its power density no longer has a highly focused distribution characteristic, which can fundamentally and effectively suppress the formation of glass glaze. The conventional laser beam that directly passes through the through-hole and the refracted beam generated by the solid area of ​​the concave lens are collectively referred to as distributed laser beams.

[0052] Preferably, the aperture concave lens (6) is a spherical concave lens; more specifically, taking the E1039M laser cutting machine as an example, such as Figures 9 to 11 As shown, the outer diameter d3 of the single-spherical concave lens is preferably 10 mm, the lens thickness T4 is 3.8 mm, the spherical curvature SR is 6.46 mm, and the height T3 from the bottom of the spherical surface to the upper surface of the lens is 1.5 mm. Of course, more preferably, the aperture concave lens (6) can be made as follows: Figure 12 The image shows a double-spherical, open-aperture concave lens.

[0053] As a preferred option, for ease of installation and disassembly, the mounting bracket (3) is fixedly mounted on the conventional laser cutting head (1) by a set screw (8).

[0054] More preferably, such as Figure 1 and Figure 3 As shown, the mounting bracket (3) is an n-shaped integrated frame structure, and its upper crossbeam (31) has a cutting head mounting through hole (not numbered); the cutting head mounting through hole is fitted with the outer circumference of the conventional laser cutting head (1); on the middle crossbeam (32) of the n-shaped integrated frame structure, a pair of set screws (8) are symmetrically arranged about the front and back of the symmetrical middle plane of the mounting bracket (3); the axes of the set screws (8) are all parallel to the Y-axis; in this way, by adjusting the screwing depth of the set screws (8), the cutting head can be adjusted along the Y-axis. Figure 1 The position of the concave lens (6) with the aperture relative to the convex lens (5) is adjusted in the Y direction as shown.

[0055] More preferably, in order to quickly prepare the mounting bracket (3), the mounting bracket (3) is prepared by 3D printing and its material is ABS. Specific Implementation Example 2:

[0057] In order to adjust and fix the aperture concave lens (6) relative to the traditional laser cutting head (1) in such a way Figure 1 The relative positions in the X direction shown are to ensure that the concave lens (6) and the convex lens (5) are reliably coaxially arranged. Based on specific embodiment 1, as a preferred embodiment, such as... Figure 4 and Figure 8 As shown, the eyeglass frame assembly (4) also includes threaded connecting posts (42) and set nuts (43); a set of threaded connecting posts (42) is symmetrically fixed on the left and right sides of the eyeglass frame (41); the number of threads in each set of threaded connecting posts (42) is not less than 1; each set of threaded connecting posts (42) movably passes through one side of the mounting bracket (3) opposite to it, and the axis of the threaded connecting post (42) is perpendicular to the axis of the mounting bracket (3). Figure 1 The X direction is parallel; the position of the concave lens (6) relative to the conventional laser cutting head (1) can be adjusted by adjusting the extension length of the threaded connecting post (42) relative to the mounting bracket (3); this position can be fixed by using the set nut (43), thereby fastening the lens frame assembly (4) to the mounting bracket (3); more specifically, in this example, as Figure 8 As shown, the number of threads in each set of threaded connecting columns (42) is 1;

[0058] More preferably, the cutting head mounting base of the present invention capable of obtaining distributed laser light further includes a position fine-tuning component (12); such as Figure 4 and Figure 8As shown, the position fine adjustment assembly (12) includes a micrometer (121); the housing of the micrometer (121) is detachably fixed on the mounting bracket (3) via a mounting base (not numbered); the measuring column of the micrometer (121) is pressed against the end face of the threaded connecting column (42); by rotating the fine adjustment knob (not numbered), the position of the aperture concave lens (6) relative to the convex lens (5) can be precisely adjusted. Specific Implementation Example 3:

[0060] To investigate the effects of different mirror distances on the size of the annular spot area and the laser power density, based on specific embodiment 2, as a preferred embodiment, the present invention provides a cutting head mounting base capable of obtaining distributed laser light, which further includes a sleeve (2) and a gasket (9); the sleeve (2) is fitted onto the conventional laser cutting head (1) and stops between the upper annular end face of the conventional laser cutting head (1) and the upper end face of the upper crossbeam (31) of the mounting bracket (3); the gasket (9) is also fitted onto the conventional laser cutting head (1) and stops between the lower end face of the upper crossbeam (31) of the mounting bracket (3) and the lower annular end face of the conventional laser cutting head (1); by increasing / decreasing the length of the sleeve (2) and correspondingly decreasing / increasing the number of gaskets (9), the spacing l1 can be quickly adjusted. Specific Implementation Example 4:

[0062] To ensure the efficient and precise operation of the distributed laser cutting head mounting base of the present invention, it is necessary not only to ensure that the lens distance is accurately set, but also to make the convex lens (5) and the aperture concave lens (6) in the conventional laser cutting head (1) coaxial as much as possible. Therefore, an assembly and adjustment method for a distributed laser cutting head mounting base, used in conjunction with specific embodiment 3 of the present invention, is characterized by comprising the following steps:

[0063] S1: Complete the initial assembly of the cutting head mounting base capable of obtaining distributed laser light, such as... Figure 1 As shown; more specifically, in this example, preliminary assembly means that the optical lens group (unnumbered) is fixedly installed in the lens frame assembly (4); the lens frame assembly (4) is set in the mounting bracket (3), and the threaded connecting post (42) passes through the mounting bracket (3); the mounting bracket (3) is fitted onto the conventional laser cutting head (1); the set screw (8) is not adjusted in depth and is not fully tightened; the extension length of the threaded connecting post (42) is not adjusted, and the set nut (43) is not fully tightened;

[0064] S2: By increasing / decreasing the length of the sleeve (2), the number of gaskets (9) is correspondingly decreased / increased, along such a path. Figure 1 The position of the concave lens (6) with opening relative to the convex lens (5) is adjusted in the Z direction, that is, the spacing l1 is adjusted.

[0065] S3: Using a micrometer (121), along as... Figure 1 Adjust the position of the concave lens (6) relative to the convex lens (5) in the X direction as shown, and then fix the position using the set nut (43);

[0066] S4: By adjusting the screw depth of the set screw (8) located on one side of the crossbeam (32) in the middle of the mounting bracket (3), along as shown... Figure 1 Adjust the position of the concave lens (6) relative to the convex lens (5) in the Y direction as shown; then tighten the set screw (8) on the other side of the middle crossbeam (32) to fix the position, so that the mounting bracket (3) is completely fastened to the conventional laser cutting head (1); combine S3 and S5 to adjust in the X and Y directions so that the convex lens (5) and the concave lens (6) are coaxial.

[0067] Preferably, in order to reduce the weight of the cutting head mounting base of the present invention that can obtain distributed laser, thereby reducing the inertia of the present invention and the tightening force of the set screw (8), after step S3, the micrometer (121) is removed and step S4 is performed.

[0068] The present invention has the following advantages:

[0069] 1) The distributed laser beam prepared using this invention not only retains the high focused power density of the core region for efficient and rapid acquisition of macroscopic fragmentation morphology such as laser grooving, but also effectively reduces the power density of the outer region, thereby fundamentally suppressing the formation of glass glaze material; therefore, the distributed laser overcomes the aforementioned limitations of traditional lasers.

[0070] 2) This invention does not require the development of a new laser cutting machine. Instead, it is based on a traditional laser cutting head and can quickly produce distributed laser without changing the existing laser cutting machine host. Therefore, this invention reduces implementation risks, technical difficulties and cost investment, while significantly shortening the research and development and manufacturing cycle of the experimental device.

[0071] 3) This invention facilitates quick assembly and disassembly, greatly shortening the testing time and improving testing efficiency;

[0072] 4) This invention can be applied as follows: Figure 1 The position of the concave lens (6) relative to the convex lens (5) can be adjusted in the X, Y and Z directions as shown. The operation is simple and the adjustment is reliable.
