Description

Technical Field

[0001] This utility model belongs to the field of laser cutting machine technology, and in particular relates to a lightweight laser cutting machine bed. Background Technology

[0002] A laser cutting machine is a machine that takes a laser emitted from a laser source, focuses it into a high-power-density laser beam through an optical path system, and then uses the laser beam to irradiate the surface of the workpiece, causing the workpiece to reach its melting or boiling point, thereby completing the cutting process.

[0003] The structure of existing laser cutting machine tool bodies is typically as follows: Figure 1 As shown, the machine tool includes two opposing sidewalls 102, which are fixed together by multiple crossbeams 101. The top of the sidewalls 102 is fixedly connected to the cutting table guide rail 103, and the inner side of the sidewalls 102 is fixedly connected to the double-layer cutting table guide rail 103. Most of the components of the laser cutting machine tool are welded from thick steel plates, and the sidewalls 102 and crossbeams 101 are huge, resulting in an excessively heavy overall weight of the laser cutting machine tool, which brings many inconveniences to the production, transportation and installation of the laser cutting machine.

[0004] Therefore, it is necessary to improve the existing laser cutting machine bed technology. Utility Model Content

[0005] The purpose of this invention is to overcome the defects in the existing technology and provide a lightweight laser cutting machine bed, which improves the convenience of laser cutting machine bed production, transportation and installation.

[0006] To achieve the above objectives, the specific technical solution of the lightweight laser cutting machine bed of this utility model is as follows: A lightweight laser cutting machine bed includes two parallel and horizontally extending main longitudinal beams. Each end of one main longitudinal beam is equipped with a column. Below each main longitudinal beam is a parallel secondary longitudinal beam, both ends of which are fixedly connected to the columns. A crossbeam is positioned between the two columns located at the same end of the two main longitudinal beams. A first track is provided on the top surface of each main longitudinal beam, and second tracks are provided on the top surface of the secondary longitudinal beam and on the opposite sides of the two main longitudinal beams. The main longitudinal beams, secondary longitudinal beams, columns, and crossbeams are all hollow square tubular structures.

[0007] Preferably, both the crossbeam and the secondary longitudinal beam are provided with weight-reducing holes.

[0008] Preferably, the main longitudinal beam is provided with internal reinforcing ribs.

[0009] Preferably, the reinforcing rib has a cross-shaped longitudinal section.

[0010] Preferably, the main longitudinal beam is provided with an L-shaped mounting bracket, and the second track is disposed on the mounting bracket.

[0011] Preferably, a U-shaped reinforcing beam is provided between the two main longitudinal beams, with both ends of the reinforcing beam fixedly connected to the two main longitudinal beams respectively, and the secondary longitudinal beam is located inside the U-shaped opening of the reinforcing beam.

[0012] Preferably, the reinforcing beam includes an integrally formed support plate and rib plate. The support plate has a U-shaped structure and is fixedly connected to both the main longitudinal beam and the secondary longitudinal beam. The rib plate is located outside the support plate, and the support plate and the rib plate are perpendicular to each other, forming a T-shaped structure.

[0013] Preferably, the end of the reinforcing beam is integrally formed with a support portion, and the support portion is connected to the bottom surface of the mounting frame.

[0014] Preferably, a support block is provided at least directly below the secondary longitudinal beam, and the support block is disposed between the support plate and the rib plate.

[0015] The lightweight laser cutting machine bed of this utility model has the following advantages: the hollow square tube structure can reduce the weight of the main longitudinal beam, secondary longitudinal beam, column and crossbeam, and compared with the existing technology, the large-volume side walls are simplified to the main longitudinal beam and secondary longitudinal beam, and the number of crossbeams is reduced, thereby greatly reducing the weight of the laser cutting machine bed, so as to improve the convenience of production, transportation and installation of the laser cutting machine bed.

[0017] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.

[0018] The terms "top surface," "bottom surface," and "full surface" refer to the normal operating state of the laser cutting machine bed and are used only for the convenience of describing this utility model and simplifying the description. They are not intended to indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on this utility model.

[0019] like Figure 2 and 3 As shown, a lightweight laser cutting machine bed includes two parallel and horizontally extending main longitudinal beams 6. Each end of the main longitudinal beam 6 is provided with a column 5. Below the main longitudinal beam 6, a parallel secondary longitudinal beam 3 is provided, with both ends of the secondary longitudinal beam 3 fixedly connected to the column 5. A crossbeam 2 is provided between the two columns 5 located at the same end of the two main longitudinal beams 6. A first track 7 is provided on the top surface of the main longitudinal beam 6, and a second track 8 is provided on the top surface of the secondary longitudinal beam 3 and on the opposite sides of the two main longitudinal beams 6. The main longitudinal beams 6, secondary longitudinal beams 3, columns 5, and crossbeam 2 are all hollow square tube structures.

[0020] The two main longitudinal beams 6 of the aforementioned laser cutting machine bed support the two first tracks 7 and the two upper second tracks 8. The two first tracks 7 are used for the laser to move on top, and the two upper second tracks 8 are used for the upper cutting table to move. The secondary longitudinal beam 3 supports the two lower second tracks 8, which are used for the lower cutting table to move. The upper and lower cutting tables are alternately used, which can improve the cutting efficiency of the laser cutting machine. The column 5 supports the main longitudinal beams 6 and the secondary longitudinal beams 3, and the crossbeam 2 supports the column, thus maintaining the stability of the overall structure of the bed. Furthermore, the main longitudinal beams 6, secondary longitudinal beams 3, column 5, and crossbeam 2 are all hollow square tube structures, which can greatly reduce the overall weight of the bed and improve the convenience of bed production, transportation, and installation.

[0021] The laser cutting machine bed and Figure 1 Compared to the existing laser cutting machine bed shown, the main longitudinal beam 6 and the secondary longitudinal beam 3 are used to support the sidewalls of the bulky raw material, and the number of crossbeams 2 is reduced to two, thus further reducing the weight of the laser cutting machine bed. The main longitudinal beam 6 needs to support both the first track 7 and the second track 8, while the secondary longitudinal beam 3 only needs to support the second track 8. Therefore, the horizontal width of the secondary longitudinal beam 3 can be reduced. While maintaining the horizontal bending resistance of the secondary longitudinal beam 3, the volume of the secondary longitudinal beam 3 is reduced, thereby further reducing the weight of the laser cutting machine bed, improving the convenience of bed production, transportation and installation, and reducing the production cost of the bed.

[0022] Further improvements include, for example Figure 2 and 3 As shown, both the crossbeam 2 and the secondary longitudinal beam 3 have weight-reduction holes 201. The crossbeam 2 is used to fix the two columns 5 and keep them vertical, while the secondary longitudinal beam 3 is only used to support one second track 8. Therefore, compared with the main longitudinal beam 6, the strength requirements for the crossbeam 2 and the secondary longitudinal beam 3 are relatively low. By opening weight-reduction holes 201 on them, the weight of both can be reduced while ensuring the strength requirements, thus achieving a weight-reduction effect on the laser cutting machine bed.

[0023] Further improvements include, for example Figure 6 As shown, the main longitudinal beam 6 has internal reinforcing ribs 601 with a cross-shaped longitudinal section. The cross-shaped reinforcing ribs 601 can support the four sides of the main longitudinal beam 6, thereby improving the deformation resistance of the side walls of the main longitudinal beam 6. Furthermore, by controlling the thickness of the reinforcing ribs 601, the overall weight of the main longitudinal beam 6 can be effectively controlled, thus achieving a balance between strength and lightweight. This allows the main longitudinal beam 6 to have sufficient strength to support the first track 7 and the second track 8 while also having a smaller weight, ultimately reducing the weight of the laser cutting machine bed.

[0024] Further improvements include, for example Figure 6 As shown, an L-shaped mounting bracket 9 is provided on the main longitudinal beam 6, and a second track 8 is mounted on the mounting bracket 9. The mounting bracket 9 is horizontally distributed along the extension direction of the main longitudinal beam 6. The mounting bracket 9 includes a vertical part and a horizontal part. The vertical part is fixedly connected to the mounting bracket 9, and the horizontal part is fixedly connected to the second track 8, thereby fixing the second track 8 to the main longitudinal beam 6. At the same time, the mounting bracket 9 also acts as a reinforcing rib to further improve the structural strength of the main longitudinal beam 6.

[0025] Further improvements include, for example Figure 2-4 As shown, a U-shaped reinforcing beam 4 is also provided between the two main longitudinal beams 6. The two ends of the reinforcing beam 4 are fixedly connected to the two main longitudinal beams 6 respectively, and the secondary longitudinal beam 3 is located inside the U-shaped opening of the reinforcing beam 4. The reinforcing beam 4 is divided into a horizontal section and two vertical sections. The vertical section and the horizontal section are an integral structure. The vertical section supports the main longitudinal beams 6 from the bottom, reducing the probability of bending while allowing the main longitudinal beams 6 to have a large span. The horizontal section is located below the secondary longitudinal beams 3 and can directly abut against the ground, thus supporting the secondary longitudinal beams 3 and reducing the probability of bending. Furthermore, the reinforcing beam 4 can also reinforce the connection between the main longitudinal beams 6 and the secondary longitudinal beams 3, as well as between the two secondary longitudinal beams 3, to improve the overall structural strength of the laser cutting machine.

[0026] Further improvements include, for example Figure 3 and 5As shown, the reinforcing beam 4 includes an integrally formed support plate 403 and a rib plate 404. The support plate 403 has a U-shaped structure and is fixedly connected to both the main longitudinal beam 6 and the secondary longitudinal beam 3. The rib plate 404 is located on the outside of the support plate 403. The support plate 403 and the rib plate 404 are perpendicular to each other and are combined to form a T-shaped structure. The end of the reinforcing beam 4 is integrally formed with a support part 402, which is connected to the bottom surface of the mounting frame 9. At least a support block 401 is provided directly below the secondary longitudinal beam 3, and the support block 401 is located between the support plate 403 and the rib plate 404. By arranging the support plate 403 and rib plate 404 into a T-shaped structure, the bending resistance of the reinforcing beam 4 can be improved, and the weight of the reinforcing beam 4 can be reduced, achieving a balance between the weight and strength of the reinforcing beam 4, thereby reducing the weight of the laser cutting machine bed and improving the strength of the bed. The support block 401 can increase the thickness of the rib plate 404, preventing it from bending, so that the reinforcing beam 4 located below the secondary longitudinal beam 3 can bear greater pressure, so as to provide a more stable support effect for the secondary longitudinal beam 3, thereby improving the stability of the laser cutting machine bed. The support part 402 extends to the bottom of the mounting frame 9, which can support the mounting frame 9, reduce the probability of the mounting frame 9 bending, thereby improving the stability of the second track 8, and ultimately further improving the stability of the laser cutting machine bed.
