Description

Technical Field

[0001] This utility model relates to the field of water-guided laser processing technology, and more specifically, to a water-guided laser processing fixture. Background Technology

[0002] Water-guided laser processing equipment is a special type of processing equipment in laser technology. Its core principle lies in using water as a light-guiding medium to transmit laser light. Water has high transparency and low loss characteristics for lasers of specific wavelengths, which allows the laser to propagate in water along a specific path, similar to the principle of fiber optic light guiding. At the same time, the high specific heat capacity of water allows it to quickly absorb and dissipate heat during laser processing, effectively reducing the heat-affected zone of the processing area and effectively preventing problems such as material deformation or microcracks caused by high temperatures.

[0003] In the prior art, document CN221910296U discloses a high-power water-guided laser precision machining device. In this device, a filter screen is set on one side of the machining table, and a spiral conveyor blade for conveying metal impurities is installed inside the filter screen. However, when irregular metal impurities generated during cutting enter the filter screen, they are easily stuck in the mesh of the filter screen. At this time, conveying them by the spiral conveyor blade will generate a large friction force, resulting in poor impurity removal effect and damage to the filter screen. Utility Model Content

[0024] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this utility model. In this utility model, unless otherwise expressly specified and limited, the term "fixed connection" should be interpreted broadly. For example, "fixed connection" can mean fixed installation, detachable connection, or integral; it can mean mechanical connection or electrical connection; it can mean direct connection. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0025] In water-guided laser processing, the focused laser beam is guided by a high-pressure water jet and directly transmitted to the workpiece surface. The water jet not only serves as a transmission medium for the laser but also plays a role in cooling and flushing, carrying away the molten material and heat generated during processing. This significantly reduces thermal damage and contaminant deposition. Water-guided laser processing can achieve cutting effects, while water and impurities during the cutting process flow along the groove on the top of the workpiece fixing table.

[0026] In the prior art, the device sets up a filter screen on one side of the processing table and installs a spiral conveyor blade inside the filter screen to transport metal impurities. Irregular metal impurities generated during cutting are easily stuck in the mesh of the filter screen. When transported by the spiral conveyor blade, a large friction force is generated, resulting in poor impurity removal effect and damage to the filter screen.

[0027] In view of this, the present invention provides a water-guided laser processing fixture that can quickly filter impurities in water flow and facilitate the cleaning of impurities on the filter screen 17, thus avoiding damage to the filter screen 17.

[0028] like Figure 1 , Figure 2 , Figure 5 and Figure 6As shown, a water-guided laser processing fixture includes a processing table 1, a mounting frame 12 and multiple limiting plates 16. The top of the mounting frame 12 is provided with a drainage groove 13, the end of the mounting frame 12 is provided with a drainage hole 14, the inner wall of the mounting frame 12 is provided with a mounting groove 15, the limiting plates 16 are slidably connected to the inner wall of the mounting groove 15, the outer wall of each limiting plate 16 is fixedly connected with a filter screen 17, and the outer wall of each filter screen 17 is fixedly connected with a lifting rod 18.

[0029] This design can quickly filter impurities in the water flow, and at the same time facilitates the cleaning of impurities on the filter screen 17, preventing damage to the filter screen 17.

[0030] In the embodiments of this application, such as Figure 2 and Figure 3 As shown, a groove 2 is provided on the top of the processing table 1, and a liquid guide rack 6 is installed at the end of the processing table 1;

[0031] The processing table 1 has a connecting groove 3 on its side wall. The outer wall of the liquid guide frame 6 is fixedly connected to a connecting plate 4. A fixing bolt 5 is inserted into the inner wall of the connecting plate 4. The end of the fixing bolt 5 is threadedly connected to the processing table 1.

[0032] The top of the liquid guide frame 6 is provided with a liquid guide groove 7 and multiple liquid drain grooves 8. A baffle 9 is fixedly connected to the top of the liquid guide frame 6. The liquid guide groove 7 and the liquid drain grooves 8 are respectively connected to the corresponding grooves 2.

[0033] This design allows the liquid guide trough 7 and the liquid drain trough 8 to precisely guide the water flow into the mounting frame 12.

[0034] In the embodiments of this application, such as Figure 4 As shown, a support plate 10 is fixedly connected to the outer wall of the liquid guide frame 6, and a groove 11 is provided on the top of the support plate 10. The mounting frame 12 is slidably connected to the inner wall of the groove 11.

[0035] In this design, the groove 11 at the top of the tray 10 can support the bottom of the mounting frame 12.

[0036] In the embodiments of this application, such as Figure 7 As shown, a fixing plate 19 is fixedly connected to the outer wall of the liquid guide frame 6, a positioning plate 20 is fixedly connected to the outer wall of the mounting frame 12, a positioning rod 22 is slidably connected to the inner wall of the fixing plate 19, a limit ring 24 is fixedly connected to the outer wall of the positioning rod 22, a spring 23 is sleeved on the outer wall of the positioning rod 22, the bottom of the positioning rod 22 passes through the positioning plate 20 and is slidably connected to it, one end of the spring 23 is fixedly connected to the fixing plate 19, and the other end of the spring 23 is fixedly connected to the positioning plate 20.

[0037] In this design, pulling the positioning rod 22 upwards allows it to be pulled out from the bottom of the positioning plate 20, thus removing the mounting frame 12 for easy cleaning. After cleaning, the mounting frame 12 is slid into the bracket 11. At this point, the guide surface 21 on the positioning plate 20 presses against the bottom of the positioning rod 22, and under the elastic force of the spring 23, the positioning rod 22 quickly snaps into the positioning plate 20, thereby fixing the mounting frame 12.

[0038] In the embodiments of this application, such as Figure 7 As shown, the outer wall of the positioning plate 20 is provided with a guide surface 21, and the bottom of the positioning rod 22 is a semi-circular structure;

[0039] This design, with its guide surface 21 and semi-circular structure, allows the positioning rod 22 to be quickly engaged with the positioning plate 20 during the installation of the mounting frame 12, by pressing the positioning rod 22 against the positioning plate 20.

[0040] Working principle: During the processing, the water-guided cutting equipment generates a lot of water. The water is guided into the liquid guide frame 6 through the groove 2 on the top of the processing table 1, and then guided into the mounting frame 12 at the front end of the filter screen 17 through the liquid guide groove 7 on the liquid guide frame 6. The water is also guided into the mounting frame 12 through the drain groove 8, while metal scraps are flushed into the mounting frame 12.

[0041] Water flows along the inner wall of the mounting frame 12 and passes through multiple filters 17 to filter impurities in the water flow in sequence. The filtered water is discharged through the drain hole 14, while the impurities are retained in the limiting plate 16.

[0042] During cleaning, hold the lifting rod 18 to lift the filter screen 17 and the limiting plate 16 out of the mounting frame 12, so as to facilitate the cleaning of impurities in the limiting plate 16;

[0043] Pull the positioning rod 22 upwards to remove it from the positioning plate 20 from the bottom. This allows the mounting frame 12 to be removed, making it easier to clean. After cleaning, slide the mounting frame 12 into the bracket 11. At this time, the guide surface 21 on the positioning plate 20 presses against the bottom of the positioning rod 22. Under the elastic force of the spring 23, the positioning rod 22 quickly snaps into the positioning plate 20, thereby fixing the mounting frame 12.

[0044] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
