Description

Technical Field

[0001] The present invention relates to the intersection of optical engineering, geotechnical engineering and mechanical engineering, and relates to a laser cutting head and an assembly and adjustment method thereof, and in particular to a cutting head mounting seat capable of obtaining distributed laser based on a traditional laser cutting head and an assembly and adjustment method thereof. Background Art

[0002] At present, laser rock breaking technology is mainly used in the field of mineral energy mining such as oil and natural gas. In the future, it is an inevitable development trend to optimize and improve laser cutting machines, improve the rock breaking effect of laser rock breaking technology, and further couple laser rock breaking technology to TBM (full-section rock tunnel boring machine), anchor drilling machine, drilling machine, open-pit mining machine and other large-scale rock cutting equipment (hereinafter referred to as cutting equipment).

[0003] The existing laser cutting machine emits a straight circular laser (hereinafter referred to as the traditional laser) through its laser cutting head (hereinafter referred to as the traditional laser cutting head). Because the power density of the traditional laser is too concentrated, a large amount of rock is melted into lava in a short time, or even vaporized; a small part of the lava will be blown out of the laser groove in time, while most of it will adhere to the wall of the laser groove, which will solidify into a smooth glassy covering layer (hereinafter referred to as glass glaze) after cooling. Studies have shown that due to the presence of glass glaze, the traditional laser rock breaking still has the following limitations: 1) With the increase of laser power, the laser energy efficiency and rock breaking effect no longer increase significantly. This is because the large amount of glass glaze 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 the deep rock layer; 2) The glass glaze produces a similar effect to that of an adhesive, constantly bonding the rock cracks that have already occurred, which is not conducive to the extension, expansion and intersection of macro and micro cracks, reducing the rock breaking effect. Researchers have tried to inhibit the formation of glass glaze by adjusting laser irradiation mode, cooling technology, surface pretreatment, etc., but the results have been minimal because the wavefront shape and highly focused optical properties of traditional lasers have not been fundamentally changed.

[0004] In view of the shortcomings of existing laser cutting machines, if we start from the bottom-level components and re-develop a new set of laser cutting machines, there are limitations such as high risk, high difficulty, high cost, and long production and development cycle. Especially when coupling laser rock breaking technology to large-scale rock cutting equipment, since the research is in the early stage of feasibility verification, the development of a high-power and full-size new laser cutting machine obviously has huge R&D risks. How to quickly and economically prepare a new type of laser that can effectively suppress the formation of glass glaze based on traditional laser equipment, especially without changing the host of the existing laser cutting machine, based on the traditional laser cutting head, so as to quickly carry out feasibility verification tests is an urgent problem to be solved by researchers in this field.

When the absolute position of the described object changes, the relative position relationship also changes accordingly.

[0045] like Figures 1 to 12 , are all drawings of the present invention.

[0046] Before introducing the present invention, it is necessary to take the E1039M laser cutting machine as an example to introduce the beam forming principle of traditional lasers. In the main machine of this type of laser cutting machine, the CO2 laser generator (not shown) first generates an initial beam (not shown), which is then output through a light guide (not shown) and a bellows (not shown) to generate a stable beam (not shown); then, the stable beam is then guided through a phase shifter (not shown) and a reflector (not shown) in turn, and is generated through a focusing lens (not shown) as shown in FIG. Fig.12 As shown in the preliminary focusing beam (10); Figures 1 to 4 As shown, the conventional laser cutting head (1) is mounted on a three-axis walking mechanism (also referred to as a moving beam, not shown) of a laser cutting machine, and a convex lens (5) is embedded in the conventional laser cutting head (1); Figure 4 and Fig.12 As shown, the initial focused light beam (7) enters the convex lens (5) provided in the conventional laser cutting head (1) via the transmission optical fiber (not shown), and finally emits a conventional laser with a diameter of d4; the conventional laser is emitted through the emission port (not numbered) of the conventional laser cutting head (1) and forms a circular light spot with an outer diameter of d4 on the surface of the rock (11); research shows that the power density distribution in the circular light 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 embodiment 1:

[0048] In order to economically and efficiently prepare a new type of laser that can effectively inhibit the formation of glass glaze while ensuring rock breaking efficiency, so as to quickly carry out feasibility verification tests, such as 1 to Fig.11 As shown, the present invention provides a cutting head mounting seat capable of obtaining distributed laser, characterized in that:

[0049] It comprises a mounting bracket (3), a mirror frame assembly (4), and an optical lens group (unnumbered), wherein:

[0050] The frame assembly (4) includes a frame (41); the optical lens group includes an apertured concave lens (6); Figures 9 to 11 As shown, a through hole with a diameter of d2 is provided at the center of the hole-opening concave lens (6); d2 is smaller than the diameter d4 of the conventional laser emitted by the conventional laser cutting head (1); Figure 8 As shown, a mounting through hole is provided at the center of the lens frame (41), and an open hole concave lens (6) is provided therein; the lens frame assembly (4) is provided in the mounting bracket (3); the mounting bracket (3) is detachably fastened to the conventional laser cutting head (1); Fig.12 As shown, the apertured concave lens (6) is located directly below the exit port of the conventional laser cutting head (1), and the apertured concave lens (6) and the convex lens (5) are spaced at a certain distance l1 (i.e., the lens distance) and are coaxially arranged, and at the same time, the apertured concave lens (6) and the rock surface are spaced at a certain distance l2 (i.e., the object distance).

[0051] Research shows that a conventional laser beam with a diameter not greater than d2 can directly pass through the through hole of the perforated concave lens (6). According to the principle of light propagation, the power density distribution characteristics of the beam directly passing through the through hole remain unchanged, that is, it is still a conventional laser, and the highly focused characteristics of the conventional laser energy density can be used to quickly prepare laser grooves; 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; and the remaining part of the conventional laser beam with a diameter exceeding d2 will generate a conical refracted beam after being refracted by the solid area of ​​the concave lens, 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, and 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), so its power density no longer has a highly focused distribution characteristic, which can effectively inhibit the generation of glass glaze fundamentally; the conventional laser beam directly passing through the through hole and the refracted beam generated by refraction by the solid area of ​​the concave lens are collectively referred to as a distributed laser beam.

[0052] Preferably, the apertured concave lens (6) is a spherical concave lens; more specifically, if the E1039M laser cutting machine is still taken as an example, 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 of the bottom of the spherical surface from the upper surface of the lens is 1.5 mm. Of course, more preferably, the apertured concave lens (6) can be used as follows Fig.12 The double spherical open hole concave lens shown.

[0053] Preferably, in order to facilitate assembly and disassembly, the mounting bracket (3) is fixed on the conventional laser cutting head (1) by means of set screws (8).

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

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

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

[0058] More preferably, the cutting head mounting seat capable of obtaining distributed laser according to the present invention further comprises a position fine-tuning component (12); Figure 4 and Figure 8As shown, the position fine-tuning assembly (12) comprises a micrometer (121); the housing of the micrometer (121) is detachably fixed on the mounting bracket (3) via a mounting seat (not numbered); the measuring column of the micrometer (121) is pressed against the end surface of the threaded connection column (42); and the position of the apertured concave lens (6) relative to the convex lens (5) can be accurately adjusted by rotating the fine-tuning knob (not numbered). Specific embodiment 3:

[0060] In order to explore the influence of different mirror distances on the size of the annular spot area and the laser power density, based on specific embodiment 2, as a preference, a cutting head mounting seat capable of obtaining distributed laser of the present invention further comprises a sleeve (2) and a gasket (9); the sleeve (2) is sleeved on the conventional laser cutting head (1) and stopped between the upper ring body 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 sleeved on the conventional laser cutting head (1) and stopped between the lower end face of the upper crossbeam (31) of the mounting bracket (3) and the lower ring body 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 embodiment 4:

[0062] In order to make the cutting head mounting seat capable of obtaining distributed laser work efficiently and accurately, it is necessary not only to ensure that the lens distance is accurately set, but also to make the convex lens (5) and the hole-opening concave lens (6) in the traditional laser cutting head (1) coaxial as much as possible. To this end, a method for assembling and adjusting a cutting head mounting seat capable of obtaining distributed laser used in conjunction with the specific embodiment 3 of the cutting head mounting seat capable of obtaining distributed laser of the present invention is characterized in that it comprises the following steps:

[0063] S1: Complete the preliminary assembly of the cutting head mounting base capable of obtaining distributed laser, such as Figure 1 As shown; more specifically, in this example, the preliminary assembly refers to the optical lens group (unnumbered) being fixedly installed in the lens frame assembly (4); the lens frame assembly (4) being arranged in the mounting bracket (3), and the threaded connection column (42) passing through the mounting bracket (3); the mounting bracket (3) being sleeved on the conventional laser cutting head (1); the screwing depth of the set screw (8) is not adjusted, and it is not fully tightened; the extension length of the threaded connection column (42) is not adjusted, and the set nut (43) is not fully tightened;
