Description

Technical Field

[0001] This utility model belongs to the field of water-guided laser processing technology, and in particular relates to a multi-channel water-guided laser processing device. Background Technology

[0002] Water-guided laser technology has a wide range of applications, including precision cutting and drilling of metals, ceramics, composite materials, and semiconductors. Its key feature is the use of a fine, hair-like water jet to deliver laser energy to the workpiece surface, ablating the material and achieving the machining process. Water-guided laser technology is a precision machining technique that uses a pulsed laser, typically with a power of 100-400W. The laser is coupled into a high-pressure water jet via fiber optics or a mirror, allowing the water jet to be directly aimed at the area to be processed during the machining process.

[0003] One processing path in this invention refers to a water jet system capable of forming a laser beam. This system includes at least a laser source, a set of fiber optic components or optical mirrors for transmitting the laser, a water-optical coupling processing head, and a high-pressure water and auxiliary gas supply system. Each processing path forms only one laser-carrying water jet, allowing processing of only one feature object, such as a hole or slit, at a time. For densely packed hole-type parts, such as combustion chambers or cones in aero-engines, where a single part has tens of thousands of holes, processing each part sequentially using existing single-channel water-guided laser machine tools would take 1-4 months, resulting in very low efficiency. Furthermore, during processing in a single path, the redistribution of the stress field causes real-time deformation of the part, potentially leading to shape and positional deviations in subsequent processing, resulting in a lower yield rate. Symmetrical processing, on the other hand, can effectively reduce deformation during part processing.

[0004] Chinese patent (CN113634880B) discloses a multi-beam water-guided laser processing device and system, which couples multiple laser beams into the same water beam through the same focusing lens. According to the definition of processing path in this solution, although it has multiple laser light sources, it is still only one processing path. Chinese patent (CN113618232A) discloses a dual-beam coupled water-guided processing head device and processing method, which uses two laser light sources and couples the two laser beams into the same water beam through a beam-combining lens group, but in essence, it only has one processing path.

[0032] This utility model provides a multi-channel water-guided laser processing device. (Reference) Figure 1 , 2 As shown, the multi-channel water-guided laser processing equipment includes at least: a machine tool base 1; a worktable 2 for fixing the workpiece 6 and mounting it on the machine tool base 1, the worktable 2 driving the workpiece 6 to rotate; several motion mechanisms mounted on the machine tool base 1; several processing channels, each processing channel corresponding to a water-guided laser processing head 401, and each water-guided laser processing head 401 mounted on a corresponding motion mechanism; the several water-guided laser processing heads 401 are circumferentially distributed along the rotation direction of the workpiece 6 and located in the same plane under the drive of the motion mechanisms. This multi-channel water-guided laser processing equipment has multiple water-guided laser processing channels in one device, such as 2, 3, or 4, etc. Each channel has an independent motion mechanism, which can realize the spatial posture and motion trajectory of the water-guided laser processing head 401. The motion mechanisms of multiple channels are mounted on the same machine tool platform and have a common positioning reference. Compared with existing single-channel processing, the processing efficiency can be increased several times. In multi-channel processing, a symmetrical layout is adopted, which helps to reduce part deformation during processing. Only one clamping and positioning is required during the processing of the workpiece 6 using the above equipment; disassembly is not required in the middle.

[0033] like Figure 3As shown, the processing path includes: a laser 402, an auxiliary machine 403, and a water-guided laser processing head 401. The laser 402 is connected to the water-guided laser processing head 401 via a transmission fiber optic cable 404, and the auxiliary machine 403 is connected to the water-guided laser processing head 401 via an air pipe 405 and a water pipe 406. The laser 402 is connected to the water-guided laser processing head 401 via the transmission fiber optic cable 404, which can also be replaced by a mirror assembly. The auxiliary machine 403 provides high-pressure water, compressed air, and He, and is connected to the water-guided laser processing head 401 via the water pipe 406 and the air pipe 405. During operation, the water-guided laser processing head 401 ejects a water beam carrying the laser to process the workpiece 6. Multiple lasers 402 can be configured separately, or a single laser 402 can be used to split the beam into multiple paths using a shutter; multiple auxiliary machines 403 can be configured separately, or a single auxiliary machine 403 can be used, with valves used to output water and air to multiple paths respectively.

[0034] In some embodiments, a control system 5 is also included, which is electrically connected to the laser 402, auxiliary machine 403, and motion mechanism. The control system 5 mainly consists of a PLC, an industrial computer, and a motion control system 5CNC. The PLC is the main controller. The power supply and control circuitry of the machine tool's motion mechanism are connected to the motion control system 5CNC via integrated cables. The water-guided laser processing head 401 is also connected to the PLC of the control system 5 via integrated cables. The above equipment is centrally controlled and works collaboratively under a single control system 5. Optionally, CAM software is used to plan processing tasks for multiple pathways in different areas, prioritizing symmetrical processing to reduce part deformation.

[0035] Water-guided laser processing technology is commonly used for precision drilling and cutting. Its principle is as follows: Figure 4 As shown, the laser is focused by a focusing lens, passes through a glass window into a sealed water cavity, and is aligned with a nozzle with a diameter of 40-100μm at the bottom of the sealed water cavity. High-pressure water is ejected through the nozzle to form a water jet. The laser entering the water jet undergoes total internal reflection at the water-air interface, and the laser energy is transferred to the workpiece 6. The light energy is converted into heat energy, forming a high-temperature plasma that ablates the material, forming a processing area to achieve material removal processing, which is used for drilling, cutting, chamfering, grooving, thinning, etc.

[0036] In some embodiments, the motion mechanism includes: a motion mechanism X-axis 301, a motion mechanism Y-axis 302, and a motion mechanism Z-axis 303, wherein the motion mechanism X-axis 301, the motion mechanism Y-axis 302, and the motion mechanism Z-axis 303 are perpendicular to each other.

[0037] Continue as Figure 1As shown, when workpiece 6 is vertically mounted on machine tool base 1, each motion mechanism includes: motion mechanism X-axis 301, motion mechanism Y-axis 302, and motion mechanism Z-axis 303; motion mechanism Y-axis 302 is horizontally mounted on machine tool base 1, motion mechanism Z-axis 303 is vertically mounted on motion mechanism Y-axis 302, and motion mechanism X-axis 301 is mounted on motion mechanism Z-axis 303 and perpendicular to motion mechanism Z-axis 303 and motion mechanism Y-axis 302. Furthermore, each motion mechanism also includes: motion mechanism A-axis 304 connected to motion mechanism X-axis 301, and motion mechanism B-axis 305 connected to motion mechanism A-axis 304; workpiece 6 is mounted on motion mechanism B-axis 305; motion mechanism A-axis 304 is rotatably connected to motion mechanism X-axis 301, and motion mechanism B-axis 305 can rotate within a certain angle range around the connection point between motion mechanism B-axis 305 and motion mechanism A-axis 304.

[0038] As one of the typical embodiments, Figure 1 This is a schematic diagram of a vertical, two-channel water-guided laser processing equipment. The workpiece 6 is horizontally fixed on a rotary table 2 and rotates within a horizontal plane. Its structural features include: each water-guided laser processing channel has an independent motion mechanism, allowing individual control of its posture and trajectory; simultaneously, multiple channels are centrally controlled by a single control system 5. To achieve a unified positioning reference, both motion mechanisms and the table 2 are fixed to a machine tool base 1, thus ensuring consistent machine tool reference coordinates.

[0039] The first-path water-guided laser processing head 401 is mounted on a two-dimensional oscillating head. This oscillating head has two rotation axes, namely the first-path motion mechanism A-axis 304 and the first-path motion mechanism B-axis 305, which rotate around the X and Y axes respectively, providing the first-path water-guided laser processing head 401 with highly flexible spatial attitude control. This capability is indispensable when processing large-angle or irregularly shaped holes. For example, the multiple holes in the combustion chamber of an aero-engine have varying angles and require real-time attitude adjustment.

[0040] The motion mechanism also has three linear axes, namely the Y-axis 302 of the first path motion mechanism, the Z-axis 303 of the first path motion mechanism, and the X-axis 301 of the first path motion mechanism. The aforementioned A and B rotating heads are mounted on the X-axis 301 of the first path motion mechanism.

[0041] The second path is similar to the first path, with a motion mechanism consisting of two rotary axes (B-axis 305 and A-axis 304) and three linear axes (Z-axis 303, X-axis 301, and Y-axis 302). The second path water-guided laser processing head 401 is mounted on the aforementioned motion mechanism. The workpiece 6 is fixed on the rotary table 2.

[0042] The control system 5 mainly consists of a PLC, an industrial computer, and a motion control system 5CNC. The PLC is the main controller. The power supply and control circuitry of the machine tool's motion mechanism are connected to the motion control system CNC in the control system 5 via integrated cables. The water-guided laser processing head 401 is also connected to the PLC of the control system 5 via integrated cables. The first-path laser 402, the second-path laser 402, the first-path auxiliary machine 403, and the second-path auxiliary machine 403 are connected to the PLC of the control system 5 via control cables.

[0043] The aforementioned vertical 2-channel water-guided laser processing equipment includes a rotary table 2 with a total of 11 motion axes. Depending on the processing object, the equipment control system 5 has two modes. The first mode connects all motion axes to a single motion control system 5CNC, enabling arbitrary 5-axis linkage during processing. The second mode connects two sets of motion axes to separate motion control systems 5CNC, each capable of 5-axis linkage, with both systems centrally controlled by a PLC.

[0044] For example, when machining combustion chamber film gas holes, since the angle of each row of holes is the same, once the initial angles are aligned, each motion mechanism only needs two linear axes for interpolation to complete the circular hole trajectory during machining. Only four linear axes participate in the linkage at the same time, so the first control mode is sufficient. If the angles of each hole are different, or even if the holes are irregularly shaped, the second control mode is required. The specific method used depends on the machining characteristics.

[0045] Continue as Figure 2 As shown, when workpiece 6 is mounted horizontally, the motion mechanism includes: several motion mechanism X-axis 301, motion mechanism Y-axis 302, and several motion mechanism Z-axis 303; motion mechanism Y-axis 302 is horizontally mounted on machine tool base 1, and worktable 2 is mounted on motion mechanism Y-axis 302; motion mechanism X-axis 301 is horizontally mounted on machine tool base 1, and motion mechanism Z-axis 303 is vertically mounted on motion mechanism X-axis 301; workpiece 6 is mounted on motion mechanism Z-axis 303.

[0046] As a typical embodiment, the appendix Figure 2 A schematic diagram of a horizontal two-channel water-guided laser processing device is provided. The workpiece 6 is fixed on a vertically placed rotating worktable 2. Its control method is similar to that of the vertical two-channel water-guided laser processing device described above. When used for cutting, the two water-guided laser processing heads 401, driven by three motion axes, are aligned with the two ends of the same cutting trajectory on the workpiece 6, remaining fixed in their positions while the rotating worktable 2 rotates, thus achieving high-efficiency slicing. When used for drilling, the workpiece 6 does not need to rotate continuously; instead, it stops when the position to be processed reaches the corresponding position of the processing head, and then rotates to the next position after processing.

[0047] It should be noted that the configuration of the motion mechanism is not limited to... Figure 1 , Figure 2 The form shown can also be adopted in the form of industrial robots, gantry machine tools, etc.

[0048] The spatial arrangement of multiple processing heads can be as follows. When there are two passages, an auxiliary one can be used. Figure 5 , 6 The layout method, attached Figure 5 There are two processing paths, symmetrically distributed at 180° around workpiece 6; (Attached) Figure 6 This configuration features two processing pathways distributed at 90° intervals; when there are three pathways, an additional... Figure 7 The layout method, attached Figure 7 There are three machining paths symmetrically distributed at 120° around workpiece 6. Figure 8 The three processing pathways are arranged at 90° intervals; when there are four pathways, an additional... Figure 9 The arrangement is such that the four processing paths are symmetrically distributed at 90° around workpiece 6.

[0049] During operation, the spatial relationship between the various water-guided laser processing paths, the workpiece 6, and the machine tool can have multiple arrangements. A typical example is:

[0050] Workpiece 6 is installed horizontally (corresponding to vertical machining), and is in the horizontal plane with each machining path;

[0051] Workpiece 6 is installed vertically (corresponding to horizontal machining), and is located in the vertical plane with each machining path;

[0052] Workpiece 6 is installed at a certain angle to the ground. Workpiece 6 and each processing channel are on the same plane and at the same angle to the ground.

[0053] The above typical spatial positions do not encompass all states; they only represent the case where the machining features of workpiece 6 are symmetrically distributed. When the machining features of workpiece 6 are not symmetrically distributed, each machining channel independently completes its own machining task. During this machining process, it is necessary to prevent interference from the motion mechanism.

[0054] The processing method of the above-mentioned multi-channel water-guided laser equipment includes: fixing the workpiece 6 on the worktable 2, and fixing the worktable 2 on the machine tool base 1; fixing a plurality of motion mechanisms on the machine tool base 1; connecting a plurality of water-guided laser processing heads 401 of processing channels to each motion mechanism; the motion mechanisms driving the water-guided laser processing heads 401 to move in three mutually perpendicular directions X, Y, and Z, and / or the motion mechanisms driving the water-guided laser processing heads 401 to rotate to adjust the water-guided laser processing heads 401 to reach the processing features of the workpiece 6; and the plurality of motion mechanisms driving the plurality of water-guided laser processing heads 401 to be distributed circumferentially in the same plane along the rotation direction of the workpiece 6; when the processing features of the workpiece 6 are symmetrically distributed, the plurality of motion mechanisms driving the plurality of water-guided laser processing heads 401 to process each processing feature of the workpiece 6 simultaneously; when the processing features of the workpiece 6 are asymmetrically distributed, each motion mechanism driving each water-guided laser processing head 401 to process each processing feature of the workpiece 6 respectively.

[0055] The aforementioned multi-path water-guided laser processing method, by rationally arranging more water-guided laser processing paths on a single device, i.e., multiple water beams carrying lasers, combined with a special machine tool structure and control method, can achieve simultaneous processing of multiple different features of the same part. Without increasing the power of the laser 402 or changing the process parameters of a single channel, it achieves a geometric increase in processing efficiency. At the same time, the simultaneous symmetrical processing of multiple paths can significantly reduce part deformation and improve processing quality.

[0056] In some embodiments, the method further includes: using offline programming software or manual programming to assign the machining features on the workpiece 6 to different machining paths, forming a machining program that includes machining posture, motion trajectory, and machining parameters; downloading the machining program to the control system 5 to drive each motion mechanism and machining path to simultaneously process the workpiece 6. The specific flow of the above-mentioned multi-path water-guided laser processing method is as follows: Figure 10 As shown.

[0057] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0058] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
