[0037] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0038] See Figures 1 to 7 As shown, a CNC machine tool suitable for water-guided laser processing includes a worktable 1, a processing component 2, a fixing mechanism 3, and a splash-proof mechanism 4. A gantry frame 11 is arranged on both sides of the worktable 1. An X-axis moving component 12 is arranged on each of the two gantry frames 11. A Y-axis moving component 13 is arranged between the two X-axis moving components 12. A Z-axis moving component 14 is arranged on the Y-axis moving component 13. The processing component 2 is arranged on the Z-axis moving component 14. The processing component 2 includes a columnar mounting base 21 vertically arranged on the Z-axis moving component 14, and a water-guided laser head is arranged at the end of the columnar mounting base 21. 22; A frustum-shaped opening processing block 15 is provided at the center of the worktable 1. A mounting ring 16 is also coaxially provided on the opening processing block 15. A fixing mechanism 3 for locking the workpiece is provided inside the mounting ring 16. A splash-proof mechanism 4 is provided on the columnar mounting base 21 and can intercept liquid and processing residue during the processing. The splash-proof mechanism 4 includes a rotating ring 41 coaxially rotatably provided on the columnar mounting base 21. The rotating ring 41 is connected to a corresponding ring 43 through a frustum-shaped rubber cover 42. The side of the corresponding ring 43 near the worktable 1 is magnetically attracted to the corresponding side of the mounting ring 16.

[0039] To better process the workpiece and avoid secondary contamination caused by flying debris during processing, the Z-axis moving assembly 14 separates the co-position ring 43 from the mounting ring 16. Then, the worker places the workpiece inside the mounting ring 16 and fixes it using the fixing mechanism 3. Subsequently, the co-position ring 43 and the mounting ring 16 are coaxially arranged. The co-position ring 43 and the mounting ring 16 are magnetically attracted to each other, thereby ensuring the relative stability between the co-position ring 43 and the mounting ring 16 during processing and ensuring the sealing effect between the mounting ring 16 and the co-position ring 43. Subsequently, the X-axis moving assembly 12, Y-axis moving assembly 13, and Z-axis moving assembly 14 enable the water-guided laser head 22 to process the workpiece in the X, Y, and Z directions. At this time, the opening processing block 15, mounting ring 16, rubber cover 42, and positioning ring 43 form a sealed environment, which not only avoids the influence of strong winds and dust particles in the external environment on the water flow and laser during the processing, but also blocks the flying debris and liquid during the cutting process, ensuring safety. Secondly, the rubber cover 42 can be stretched accordingly as the water-guided laser head 22 moves, thereby ensuring a sealing effect.

[0040] See Figure 2 and Figure 3 As shown, the fixing mechanism 3 includes a threaded sleeve 31 and a threaded rod 32; a cross mounting bracket 161 is provided inside the mounting ring 16, and a sliding groove 162 is provided at each end of the cross mounting bracket 161. The mounting ring 16 is provided with four rotating holes 163 around its circumference. A threaded sleeve 31 is rotatably provided in each rotating hole 163. A threaded rod 32 is threadedly connected inside each threaded sleeve 31. A sliding block 321 is provided at one end of each threaded rod 32 that extends into the mounting ring 16. The sliding block 321 is slidably provided in the corresponding sliding groove 162. An arc-shaped positioning block 322 is provided at the end of each sliding block 321.

[0041] Using the cross-shaped mounting bracket 161, the worker places the workpiece at the center of the bracket. Then, by adjusting the corresponding threaded sleeves 31, the four threaded sleeves 31 rotate synchronously. Since the ends of the threaded rods 32 are slidably connected to the sliding grooves 162 on the cross-shaped mounting bracket 161 through the sliding blocks 321, the threaded rods 32 can move along their axes as the threaded sleeves 31 rotate. The four threaded rods 32 can move closer to each other synchronously, thereby achieving rapid fixation of the workpiece and facilitating subsequent processing.

[0042] See Figure 2 to Figure 5As shown, the opening processing block 15 is also provided with a drive mechanism 5 for synchronously rotating multiple threaded sleeves 31; the drive mechanism 5 includes a gear ring 51, a drive motor 52 and a drive gear 53; the gear ring 51 is coaxially and rotatably mounted on the opening processing block 15, and the gear ring 51 has multiple tooth grooves 511 arranged in the circumferential direction near the circumference, and each threaded sleeve 31 has a synchronous gear 311 arranged at one end extending outside the mounting ring 16, and the synchronous gear 311 meshes with the tooth grooves 511 on the gear ring 51; the drive motor 52 is mounted on the worktable 1, and the drive gear 53 is arranged on the output shaft of the drive motor 52, and the drive gear 53 meshes with the gear ring 51.

[0043] The drive motor 52 drives the drive gear 53 to rotate. As the drive gear 53 rotates, the corresponding gear ring 51 rotates. The tooth groove 511 on the gear ring 51 meshes with the corresponding multiple synchronous gears 311, thereby driving multiple threaded sleeves 31 to rotate synchronously. As the multiple threaded sleeves 31 rotate, they drive multiple threaded rods 32 to move synchronously, so that the arc-shaped positioning block 322 at the end of the threaded rod 32 can fix the workpiece in the center, thereby facilitating the processing of the workpiece and ensuring the stability of the workpiece.

[0044] See Figures 2 to 7 As shown, the columnar mounting base 21 is also provided with a guiding mechanism 6 for guiding the splashing water flow; the guiding mechanism 6 includes an arc-shaped vertical bar 61, an arc-shaped inclined plate 62, and an arc-shaped vertical plate 63; the end of the columnar mounting base 21 is provided with an annular groove 211, and there are multiple arc-shaped vertical bars 61, which are arranged vertically in sequence in the annular groove 211. The multiple arc-shaped vertical bars 61 are arranged in a ring, and one end of each arc-shaped vertical bar 61 that extends into the annular groove 211 is provided with a locking block 611 to prevent the arc-shaped vertical bar 61 from falling off. The annular groove 21 is provided with an annular receiving groove 21 that cooperates with the locking block 611. 2. A pressure spring 612 is provided between each card block 611 and the bottom inner wall of the annular groove 211; each arc-shaped vertical bar 61 is provided with an arc-shaped inclined plate 62 that is inclined toward the axis of the columnar mounting base 21 at the end away from the annular groove 211. The arc-shaped inclined plate 62 is set at an obtuse angle with the corresponding arc-shaped vertical bar 61. Each arc-shaped inclined plate 62 is provided with an arc-shaped vertical plate 63 that extends vertically upward at the end away from the arc-shaped vertical bar 61. Multiple arc-shaped vertical plates 63 form an annular shape for protecting the water column. Each arc-shaped inclined plate 62 is also provided with a guide groove 621 for water flow at the end near the arc-shaped vertical plate 63.

[0045] Because splashing water can come into contact with the water column guiding the laser, thus affecting the laser's accuracy, multiple arc-shaped vertical strips 61 are provided at the end of the columnar mounting base 21. Each arc-shaped vertical strip 61 is slidably positioned within the annular groove 211 via a locking block 611. When processing the workpiece, multiple arc-shaped inclined plates 62 abut against the surface of the workpiece, and the pressure spring 612 is compressed, thereby allowing the arc-shaped inclined plates 62 to fit more closely to the workpiece. At this time, the water column is located inside the annular shape formed by the multiple arc-shaped vertical plates 63. When the water column comes into contact with the surface of the workpiece, the liquid will be discharged through the guide groove 621 on the arc-shaped inclined plate 62. Multiple arc-shaped vertical plates 63 can protect the water column, thereby preventing splashed liquid from affecting the water column guiding the laser and causing errors in laser accuracy. Furthermore, the multiple inclined arc-shaped inclined plates 62 can further block splashed liquid, reduce the splash range of liquid, and facilitate subsequent processing. Moreover, the arc-shaped inclined plates 62 can adaptively move according to the shape of the workpiece surface when the water-guided laser head 22 moves, thereby avoiding rigid contact between the arc-shaped inclined plates 62 and the workpiece and ensuring the service life of the arc-shaped inclined plates 62.

[0046] See Figure 7 As shown, the guide groove 621 has an inclined surface 622 on one side of its inner wall along the length direction.

[0047] With the inclined surface 622 provided, after the splashed water enters the guide groove 621, it can contact the inclined surface 622, thereby enabling the corresponding arc-shaped inclined piece 62 to rotate along the axis of the columnar mounting base 21. The rotation of multiple arc-shaped inclined pieces 62 not only helps to accelerate the discharge of splashed water, but the rotating arc-shaped inclined pieces 62 can also clean the surface of the workpiece, thereby preventing splashed debris from remaining on the surface of the workpiece and affecting the subsequent cutting process.

[0048] See Figure 6 As shown, a synchronization ring 64 is provided on the outside of multiple arc-shaped vertical bars 61. A guide post 613 is provided on the side of each arc-shaped vertical bar 61 away from the columnar mounting base 21. Multiple vertical grooves 641 for accommodating the corresponding guide posts 613 are provided circumferentially on the inner wall of the synchronization ring 64.

[0049] Furthermore, to ensure the stability among the multiple arc-shaped vertical bars 61, a synchronization ring 64 is provided on the outer wall of the multiple arc-shaped vertical bars 61, and a vertical groove 641 is provided on the inner wall of the synchronization ring 64. This makes the multiple arc-shaped vertical bars 61 a "whole unit". After the water column comes into contact with the surface of the workpiece, the arc-shaped vertical bars 61 can rotate synchronously through the connection of the synchronization ring 64, thereby ensuring that each arc-shaped vertical bar 61 can rotate accordingly. In addition, the setting of the vertical groove 641 allows the arc-shaped vertical bars 61 to move in the vertical direction, thereby avoiding volume collision between the arc-shaped inclined plate 62 and the protrusion on the surface of the workpiece.

[0050] See Figures 1 to 5 As shown, a collection box 17 is also provided at the center of the bottom of the workbench 1. The collection box 17 is connected to the inside of the open processing block 15. A strip-shaped notch 18 is provided on one side of the collection box 17, and a filter screen 19 is slidably installed inside the strip-shaped notch 18.

[0051] To further process the processed liquid, a collection tank 17 is provided. The processed liquid enters the collection tank 17 through the frustum-shaped processing block 15 and is filtered by the filter screen 19 to remove solid impurities. Subsequently, the liquid in the collection tank 17 can be reused and re-entered into the water-guided laser head 22.

[0052] A method for using a CNC machine tool suitable for water-guided laser processing includes the following steps:

[0053] S1: Separate the co-position ring 43 from the mounting ring 16 by the Z-axis moving assembly 14, place the workpiece in the middle position of the cross mounting bracket 161 of the mounting ring 16, and then fix the workpiece by the arc-shaped positioning blocks 322 at the ends of the four threaded rods 32 through the drive motor 52.

[0054] S2: The Z-axis moving assembly 14 is used to attach the co-position ring 43 to the mounting ring 16. Then, the X-axis moving assembly 12, Y-axis moving assembly 13 and Z-axis moving assembly 14 move the water-guided laser head 22 to process the workpiece.

[0055] S3; After processing is completed, the co-position ring 43 is separated from the mounting ring 16, and the arc-shaped positioning block 322 is separated from the workpiece by the drive motor 52. Then, the processed workpiece is taken out and a new workpiece is put in to continue processing.

[0056] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
