Description

Technical Field

[0001] This utility model relates to the field of cutting device technology, and more specifically, to a support frame for laser cutting of metal sheets. Background Technology

[0002] Laser cutting machines use a laser beam emitted from a laser source, which is focused into a high-power-density beam through an optical path system. The laser beam irradiates the workpiece surface, causing it to reach its melting or boiling point. As the relative position of the beam and the workpiece moves, a kerf is formed in the material, achieving the cutting purpose. The support frame of a laser cutting machine typically consists of serrated racks that make point contact with the metal sheet, supporting it without affecting the laser cutting process. However, frequent contact with the high-temperature laser during prolonged use can lead to wear on the frame's tips and hardening and adhesion of high-temperature metal debris from the cut surface. This unevenness can affect the proper support of the metal sheet. Furthermore, current support frames are often fixed to the machine tool table, making replacement difficult and failing to meet usage requirements. Therefore, this application provides a support frame for laser cutting of metal sheets to address this issue. Utility Model Content

[0003] In order to overcome the above-mentioned defects of the prior art, the embodiments of this utility model provide a support frame for laser cutting of metal sheets. By setting up disassembly and assembly components, it is convenient to replace some problematic frames and assist in cleaning up debris on the frames, thereby solving the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A support frame for laser cutting of metal sheets includes a machine tool worktable. A CNC running frame is slidably connected to the top of the machine tool worktable, and a laser cutter is slidably connected to the outer side of the CNC running frame. A support base plate is located on the inner side of the machine tool worktable. A disassembly and assembly assembly is provided for convenient disassembly and assembly of the support frame. The disassembly and assembly assembly includes a base sleeve fixedly connected to the top of the support base plate. A first rack frame is inserted into the inner side of the base sleeve. The two ends of the first rack frame are respectively provided with insertion holes and insertion blocks. A fixed mounting bracket is inserted into the end of the first rack frame with insertion holes, and a second rack frame is inserted into the end of the first rack frame with insertion blocks.

[0006] In a preferred embodiment, the fixed mounting bracket is inserted into one end of the base sleeve, and the second rack bracket is inserted into the inner side of the base sleeve.

[0007] In a preferred embodiment, a fixing bolt is slidably connected inside the fixed mounting bracket, the fixing bolt is inserted into the inside of the base sleeve, and a fixing plate is fixedly connected to the inner side of the fixed mounting bracket, the fixing plate being sleeved on the top of the support base plate.

[0008] In a preferred embodiment, a transmission link is hinged to the top of the fixed plate, a side connecting plate is hinged to one end of the transmission link, and a connecting frame is fixedly connected to one end of the fixed plate.

[0009] In a preferred embodiment, a push-pull plate is fixedly connected to the top of the side connecting plate, and an installation frame is fixedly connected to one end of the side connecting plate.

[0010] In a preferred embodiment, serrated scrapers are fixedly connected to both sides of the mounting frame, and the serrated scrapers are arranged in an abutting position against the first rack frame.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] 1. This utility model, by setting up a disassembly and assembly component, divides a row of rack frames into two parts. When a rack frame is damaged or has a lot of debris attached and cannot be used, it can be disassembled and replaced. Since the damaged parts will not cover the entire row of rack frames in normal use, by replacing the damaged parts and leaving the intact parts, the cost of use can be greatly reduced. In addition, the multiple first rack frames and second rack frames are independently detachable, which can further improve the flexibility of rack frame disassembly and achieve the purpose of replacing the rack frames in the required area, thus fully meeting the various needs of actual use.

[0014] 2. This utility model, by setting up a serrated scraper and a wire brush, pushes the push-pull plate obliquely upward, and the mounting frame moves the serrated scraper and wire brush on both sides to one side of the first rack frame. The serrated scraper can remove loose and small debris from the surface of the first rack frame, and the wire brush can brush away small debris from the surface of the first rack frame, thus assisting the serrated scraper in removing debris. This can prevent debris from accumulating over a long period of use and becoming difficult to clean, thereby reducing the possibility of the first or second rack frame becoming unusable due to debris accumulation.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Refer to the instruction manual appendix Figures 1-2As shown, the support frame for laser cutting of metal sheets according to this embodiment of the utility model includes a machine tool worktable 1, a CNC running frame 15 slidably connected to the top of the machine tool worktable 1, a laser cutter 16 slidably connected to the outer side of the CNC running frame 15, a support base plate 2 on the inner side of the machine tool worktable 1, and a disassembly and assembly assembly. The disassembly and assembly assembly is used for convenient disassembly and assembly of the support frame. The disassembly and assembly assembly includes a base sleeve 3 fixedly connected to the top of the support base plate 2, a first rack frame 4 inserted into the inner side of the base sleeve 3, and insertion holes and insertion blocks respectively provided at both ends of the first rack frame 4. A fixed mounting bracket 5 is inserted into the end of the first rack frame 4 with insertion holes. The first rack frame 4 has a second rack frame 6 inserted into one end with an insert block. The first rack frame 4 and the second rack frame 6 are spliced ​​together to form a complete rack frame. The other end of the second rack frame 6 is also provided with a fixed mounting bracket 5, and the fixed mounting bracket 5 is connected to multiple first rack frames 4 or second rack frames 6, so that multiple first rack frames 4 and second rack frames 6 can be assembled and disassembled through the fixed mounting bracket 5. The fixed mounting bracket 5 is inserted into one end of the base sleeve 3, and the second rack frame 6 is inserted into the inner side of the base sleeve 3. The fixed mounting bracket 5 is slidably connected with a fixing bolt 7, which is inserted into the inside of the base sleeve 3.

[0022] It should be noted that the first rack frame 4 and the second rack frame 6 are racks with the same structure, both ends of which are provided with insertion holes and inserts. A complete rack frame can be assembled by interlocking the insertion holes and inserts of the first rack frame 4 and the second rack frame 6. By dividing the rack frame into two parts, it can be disassembled and replaced when the rack frame is damaged or has accumulated too much debris and cannot be used. Since the damaged parts will not cover the entire rack frame in normal use, replacing the damaged parts and leaving the intact parts can significantly reduce usage costs. Furthermore, the multiple first rack frames 4 and second rack frames 6 are independently detachable, further improving the flexibility of rack frame disassembly and allowing for the replacement of only the required area of ​​the rack frame, thus fully meeting various practical needs. Regarding the first rack frame... When disassembling the rack frame 4 or the second rack frame 6, the multiple first rack frames 4 and second rack frames 6 inside the fixed mounting brackets 5 on both sides can be removed by removing multiple fixing bolts 7 and then lifting them. The first rack frame 4, the fixed mounting brackets 5, and the second rack frame 6 are all plug-in connected, and can be disassembled and assembled by plugging and unplugging each other. The disassembly and assembly method is simple, convenient and easy to operate. At the same time, since the first rack frame 4 and the second rack frame 6 have the same structure, they can be arranged and combined arbitrarily. In actual use, it is convenient to change the position as needed. The same structure facilitates the production of the first rack frame 4 and the second rack frame 6. The arbitrarily arranged and combined design means that when replacing the damaged first rack frame 4 or the second rack frame 6, it is not necessary to strictly follow a specific installation method, thereby simplifying the replacement of the first rack frame 4 or the second rack frame 6.

[0023] Furthermore, such as Figures 3-4 As shown, multiple fixing plates 18 are fixedly connected to the inner side of the fixed mounting bracket 5. These fixing plates 18 are all sleeved on the top of the supporting base plate 2. A transmission connecting rod 8 is hinged to the top of each fixing plate 18. A side connecting plate 9 is hinged to one end of the transmission connecting rod 8. A connecting frame 17 is fixedly connected to one end of each fixing plate 18. The connection between the fixing plate 18 and the supporting base plate 2 improves the overall stability of the connecting frame 17. A push-pull plate 19 is fixedly connected to the top of the side connecting plate 9. A mounting frame 10 is fixedly connected to one end of the side connecting plate 9. Both the mounting frame 10 and the connecting frame 17 are rectangular hollow frames. The hollow design does not affect the falling of debris or the unloading of the finished product. Another transmission connecting rod 8 is hinged to one end of the connecting frame 17. One end of the transmission connecting rod 8 is hinged to the end of the mounting frame 10 away from the side connecting plate 9. Both sides of the mounting frame 10 are fixedly connected with serrated scrapers 11. The serrated scrapers 11 are arranged in an abutting position with the first rack frame 4. The serrated scrapers 11 are provided with serrations on the side of the serrated scrapers 11 near the first rack frame 4. The bottom of the mounting frame 10 is fixedly connected with a support spring 12. The support spring 12 is an elastic structure. The inner side of the support spring 12 is fixedly connected with a wire brush 13. The wire brush 13 is a relatively dense and elastic wire brush. The wire brush 13 is arranged in an abutting position with the base sleeve 3. The bottom end of the support spring 12 is fixedly connected with a reset plate 14. The reset plate 14 is arranged with an arc-shaped profile. The reset plate 14 is arranged in an abutting position with the base sleeve 3.

[0024] It should be noted that, after the metal sheet is cut, if there is debris adhering to the top of the first rack frame 4 or the second rack frame 6, the push-pull plate 19 can be pushed obliquely upwards to cause the side connecting plate 9 on one side and the mounting frame 10 to move obliquely upwards synchronously. At the same time, the transmission connecting rods 8 on both sides rotate, causing the mounting frame 10 to drive the saw blades 11 on both sides to move on one side of the first rack frame 4. The saw blades 11 can remove the loosely adhered and small debris from the surface of the first rack frame 4. Simultaneously, as the saw blades 11 move, the wire brush 13 moves upwards and gradually contacts the first rack frame 4 under the contraction of the support spring 12. The wire brush 13 can remove the debris. The saw blade 11 can remove small debris from the surface of the first rack frame 4, thereby assisting the saw blade 11 in removing debris. This can prevent debris from accumulating and becoming difficult to clean over time, and reduce the possibility of the first rack frame 4 or the second rack frame 6 becoming unusable due to debris adhesion. At the same time, when resetting the saw blade 11 and the wire brush 13, the saw blade 11 can be reset by pulling the push-pull plate 19 in the opposite direction. When the wire brush 13 moves down to reset, the reset plate 14 will gradually contact the top of the base sleeve 3, and the support spring 12 will be gradually stretched under the guidance of the inclined surface of the reset plate 14, so that the wire brush 13 can move down to one side of the base sleeve 3.

[0025] Finally, the following points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection", and "linkage" should be interpreted broadly, and can be mechanical or electrical connections, or internal connections between two components, or direct connections.
