Description

Technical Field

[0001] The utility model relates to the technical field of field lenses, and particularly relates to a water-cooled field lens with directional installation. Background Technique

[0002] A field lens focuses a collimated laser beam at a point to increase the energy density of the laser beam, and uses the high energy of the laser to perform various material processing such as cutting, marking, welding, cleaning, and surface treatment on materials. At the same time, when the direction of the incident laser beam changes, the field lens can still maintain a light spot with relatively unchanged size and energy density, so that the laser beam can process points at different material positions. The transfer of energy cannot reach 100%. When passing through different media, a part of the energy will be absorbed by the media. In the field lens, the lens will absorb energy, which will cause the working temperature of the field lens to rise, thus causing a series of changes, and ultimately may lead to the optical effect not meeting the use requirements. For applications such as 3D printing and cladding, stable optical performance is often required.

[0003] In the market, water cooling is often added to the mechanical structure of the field lens. Through the heat transfer between the mechanical parts and the lens, the working environment temperature of the field lens is stabilized. However, when the field lens is installed, it is often connected by threads to install the field lens at the position of the lens barrel, and it is impossible to ensure that the relative positions of the water inlet and outlet of each set of systems are the same. Furthermore, it is necessary to adjust the position of the connecting water pipe, resulting in cumbersome installation. Content of the Utility Model

[0018] The present utility model provides a water - cooled field lens with directional installation as Figures 1-4 shown, including a lens barrel 1 and a field lens 2 adapted to the lens barrel 1. A flange 9 is fixedly connected to the bottom of the lens barrel 1. Mounting holes 10 adapted to the flange holes of the flange 9 are provided on the top surface of the field lens 2. Fastening bolts 11 are provided on the surfaces of the flange holes of the flange 9. The flange 9 is fixed on the surface of the mounting hole 10 through the fastening bolts 11. A first adapter box 3 is fixedly connected to the barrel wall of the lens barrel 1. Two sleeves 4 are fixedly connected to the bottom surface of the first adapter box 3. The bottom ends of the two sleeves 4 are rotatably connected to first nuts 5. A second adapter box 6 is fixedly connected to the side surface of the field lens 2. Two water guide pipes 7 are provided on the top surface of the second adapter box 6. Both of the two water guide pipes 7 communicate with the corresponding sleeves 4. A threaded column 8 adapted to the first nut 5 is fixed on the outer wall of the water guide pipe 7;

[0019] By providing a first adapter box 3 on the outer wall of the lens barrel 1, by fixedly connecting two sleeves 4 to the bottom surface of the first adapter box 3, and fixedly connecting the bottom ends of the sleeves 4 to first nuts 5, and threadedly connecting the first nut 5 with the threaded column 8, the water guide pipe 7 is inserted into the sleeve 4 to make the water path communicate. Secondly, by threadedly connecting the fastening bolt 11 with the mounting hole 10, the field lens 2 is fixed on the lens barrel 1.

[0020] As Figure 1As shown, two connecting water pipes 21 are fixedly connected to the top end of the first adapter box 3. Both of the two connecting water pipes 21 communicate with the two sleeves 4 through the inner cavity of the first adapter box 3. The size of the first adapter box 3 facilitates the protrusion of the two sleeves 4 from the flange 9, thereby facilitating the insertion connection of the sleeves 4 with the water guide pipe 7.

[0021] As Figure 2 and Figure 3 As shown, a sealing plate 20 is provided on the top surface of the second adapter box 6. Two threaded pipes 19 are provided on the top surface of the sealing plate 20. Pressing rings are fixedly connected to the top ends of both of the two threaded pipes 19. Both of the two threaded pipes 19 are hollow and communicate with the water guide pipe 7. The bottom ends of the two threaded pipes 19 are respectively threadedly connected to the rounded corners of the first water guide groove 13 and the second water guide groove 14. A second nut 18 is fixedly connected to the top end of the threaded pipe 19. One end of the second nut 18 away from the threaded pipe 19 is fixedly connected to the bottom end of the threaded column 8. The sealing plate 20 is fixedly connected to the top end of the second adapter box 6 through the pressing ring at the top end of the threaded pipe 19. By disassembling the sealing plate 20, it is convenient to clean the impurities in the first water guide groove 13 and the second water guide groove 14.

[0022] As Figure 3 and Figure 4 As shown, a cooling water pipe 12 is fixedly connected to the inner wall of the field lens 2. A first water guide groove 13 is formed inside the second adapter box 6. A second water guide groove 14 is formed inside the second adapter box 6. One end of the second water guide groove 14 communicates with one end of the cooling water pipe 12. One end of the first water guide groove 13 communicates with the other end of the cooling water pipe 12. Through the connection of the second water guide groove 14 and the first water guide groove 13 with the cooling water pipe 12, the water circuit forms a cycle.

[0023] As Figure 3 As shown, a T-shaped plate 15 is provided on the side surface of the second adapter box 6. The T-shaped plate 15 is fixed to the side surface of the second adapter box 6 through two fixing bolts. A filter plate 16 is fixedly connected to the bottom end of the T-shaped plate 15. The filter plate 16 penetrates through the side wall of the second adapter box 6 and abuts against the side wall of the second water guide groove 14. By fixedly connecting a filter plate 16 to the bottom end on one side of the T-shaped plate 15 and inserting the filter plate 16 into the second water guide groove 14, it is convenient to intercept impurities in the water.

[0024] As Figure 4 As shown, a hand-tightening pressing ring 17 is provided at the bottom end of the field lens 2. The hand-tightening pressing ring 17 is threadedly connected to the field lens 2, and a protective lens is provided on the inner wall of the hand-tightening pressing ring 17. To update the protective lens, directly remove the hand-tightening pressing ring 17 to replace the new protective lens, and then screw on the hand-tightening pressing ring 17 to complete the replacement.

[0025] Working principle of the utility model: When in use, first insert two water conduits 7 into the inner cavities of the corresponding sleeves 4, then thread the nut 5 onto the threaded column 8 by screwing, and then align the mounting holes 10 on the surface of the field lens 2 with the flange holes of the flange plate 9. Then, fix the flange plate 9 and the scene 2 by screwing the fastening bolts 11. Therefore, the flange plate 9 at the bottom end of the lens barrel 1 is fixedly connected to the top surface of the field lens 2 by using the fastening bolts 11. Furthermore, when installing the field lens 2 each time, first fix the water circuit, and then fix the field lens 2 and the lens barrel 1, ensuring that the relative positions of the water inlets and outlets of each set of systems are consistent and reducing the installation steps;

[0026] After the fixation is completed, inject water into one of the connecting water pipes 21. The water flow is introduced into the sleeve 4 through the conduction of the adapter box 1, flows into the water guide groove 13 through the water conduit 7, and then flows into the cooling water pipe 12 through the conduction of the water guide groove 13. The water flow passing through the cooling water pipe 12 dissipates heat from the inner wall of the field lens 2, and finally flows out from the other end of the cooling water pipe 12 until the water flow flows out through the other connecting water pipe 21, achieving the effect of cooling the field lens 2.

[0027] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
