Technical Field
[0001] This utility model belongs to the field of laser cutting machine technology, and in particular relates to a 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] Patent CN206747801U discloses a laser cutting machine bed and a laser cutting machine. The laser cutting machine bed is an integrated structure. For large laser cutting machines, the integrated laser cutting machine bed structure requires the use of corresponding large processing equipment. Purchasing large processing equipment greatly increases the production cost of enterprises. In addition, large laser cutting machine beds also face multiple challenges in transportation, hoisting and installation.
[0004] Therefore, it is necessary to improve the existing laser cutting machine bed technology. Utility Model Content
[0005] The purpose of this utility model is to overcome the defects in the existing technology and provide a laser cutting machine bed that reduces production costs and improves the convenience of transportation, hoisting and installation.
[0006] To achieve the above objectives, the specific technical solution of the laser cutting machine bed of this utility model is as follows: A laser cutting machine bed includes a main body, the main body including two parallel guide rails extending horizontally along a first direction; the main body also includes multiple splicing segments, each splicing segment being sequentially connected end to end along the first direction and supported on the bottom surface of the guide rails, and adjacent splicing segments being detachably connected.
[0007] Preferably, the splicing segment includes a crossbeam, with longitudinal beams fixedly connected to both ends of the crossbeam, a support beam fixedly connected to the top of the longitudinal beam, and a bearing seat fixedly connected to the side of the support beam adjacent to the crossbeam. The support beam is fixed to the guide rail by bolt assemblies. The longitudinal beam, the bearing seat, and the support beam all extend along a first direction. Two adjacent support beams along the first direction are fixed to each other by bolt assemblies, and two adjacent longitudinal beams along the first direction are fixed to each other by fasteners.
[0008] Preferably, the longitudinal beam is a square tube structure, and a positioning block is provided between two adjacent longitudinal beams along the first direction. The two ends of the positioning block are respectively inserted and engaged with the ends of the two longitudinal beams.

[0011] Preferably, both ends of the positioning block are provided with multiple notches extending along the first direction, and the depth of the notches is less than half the length of the positioning block.
[0012] Preferably, the support beam has a U-shaped groove structure with its groove opening facing away from the crossbeam. The support beam has stiffening plates at both ends and inside, and the stiffening plates are arranged at equal intervals along the first direction.

[0016] The laser cutting machine bed of this utility model has the following advantages: the laser cutting machine bed is made of multiple identical splicing sections.

[0018] 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.
[0019] 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.
[0020] like Figure 1 and 2 As shown, a laser cutting machine bed includes a main body, which includes two parallel guide rails 2 that extend horizontally along a first direction; the main body also includes multiple splicing segments 1, which are sequentially connected end to end along the first direction and are all supported on the bottom surface of the guide rails 2, and adjacent splicing segments 1 are detachably connected.
[0021] The aforementioned laser cutting machine bed is assembled from multiple identical splicing segments 1. This divides the large machine bed into lightweight and compact splicing segments 1, reducing the requirements for production equipment when producing a single splicing segment 1, thereby lowering equipment procurement costs. Compared to the large size and weight of a one-piece machine bed, the processing, transportation, and assembly of splicing segments 1 are more convenient, thus improving the ease of processing, transportation, and assembly of the laser cutting machine bed. Furthermore, in later use, to adapt to processing workpieces of different sizes, only the number of splicing segments 1 needs to be changed to adjust the size of the laser cutting machine bed accordingly, without the need to purchase a new laser cutting machine bed, further reducing the production cost of the laser cutting machine.
[0022] In the bed of this laser cutting machine, the guide rail 2 is an integral structure. When the number of splicing sections 1 is changed, the guide rail 2 of the corresponding length needs to be replaced. Compared with the splicing guide rail 2, the integral guide rail 2 has fewer splicing gaps, which reduces vibration interference during the use of the laser cutting machine and can improve the cutting accuracy of the laser cutting machine. In addition, the integral guide rail 2 can also strengthen the connection between each splicing section 1.
[0023] Further improvements include, for example Figure 3 The splicing section 1 includes a crossbeam 103, with longitudinal beams 101 fixedly connected to both ends of the crossbeam 103. A support beam 102 is fixedly connected to the top of the longitudinal beam 101. A bearing seat 105 is fixedly connected to the side of the support beam 102 adjacent to the crossbeam 103. The support beam 102 is fixed to the guide rail 2 by bolt assemblies. The longitudinal beam 101, the bearing seat 105, and the support beam 102 all extend along a first direction. Two adjacent support beams 102 along the first direction are fixed to each other by bolt assemblies. Two adjacent longitudinal beams 101 along the first direction are fixed to each other by fasteners 3.
[0024] Specifically, the crossbeam 103 is welded and fixed to the longitudinal beam 101, and the longitudinal beam 101, support beam 102, and bearing seat 105 are welded and fixed together. The bearing seat 105 is used to place the processing platform, on which the workpiece to be cut is placed for processing. When assembling the bed, each splicing segment 1 is arranged along the first direction. After aligning the ends of the front and rear longitudinal beams 101 along the first direction, they are connected and fixed by fasteners 3. The bolt assembly includes bolts and nuts. The ends of the front and rear support beams 102 along the first direction are connected and fixed by bolt assembly. After the splicing segment 1 is connected and fixed, the guide rail 2 is finally fixed to the top of the support beam 102 by bolt assembly, thus completing the splicing of the laser cutting machine bed.
[0025] Further improvements include, for example Figure 2 and 3 The longitudinal beam 101 is a square tube structure. A positioning block 4 is provided between two adjacent longitudinal beams 101 along the first direction. The two ends of the positioning block 4 are respectively inserted and engaged with the ends of the two longitudinal beams 101. A sealing end cap 5 is detachably connected to the end of the longitudinal beam 101.
[0026] When connecting the longitudinal beams 101, the cross-sectional shape of the positioning block 4 is consistent with the inner shape of the square tube structure. Therefore, after the positioning block 4 is inserted into the end of the longitudinal beam 101, the positioning block 4 and the end of the longitudinal beam 101 can be locked together to limit the relative position between them. In this way, by inserting the two ends of the positioning block 4 into the ends of the two longitudinal beams 101 respectively, the positioning and fixing functions between the two longitudinal beams 101 can be realized. When connecting the splicing section 1, the positioning block 4 can improve the accuracy of the docking between the two splicing sections 1 and the stability of the connection structure, ultimately improving the structural strength and accuracy of the laser cutting machine bed. The sealing end cap 5 can seal the ends of the longitudinal beams 101 located at both ends of the bed to keep the inside of the longitudinal beams 101 clean and reduce the corrosion of the longitudinal beams 101.
[0027] Further improvements include, for example Figure 3 and 5As mentioned above, partition plates 106 are provided inside both ends of the longitudinal beam 101, and the distance between the partition plate 106 and the end face of the longitudinal beam 101 is equal to half the length of the positioning block 4.
[0028] Specifically, the partition 106 can firstly support the longitudinal beam 101 from the inside, thereby improving the structural strength of the longitudinal beam 101; secondly, during the insertion of the positioning block 4 into the longitudinal beam 101, the insertion depth of the positioning block 4 can be limited to ensure that the two ends of the positioning block 4 are inserted to the same depth inside the two longitudinal beams 101, thereby improving the stability of the connection between the positioning block 4 and the two longitudinal beams 101.
[0029] Further improvements include, for example Figure 5 The positioning block 4 has tapered ends with a lubricating layer on its surface. Multiple notches 401 extending in the first direction are provided at both ends of the positioning block 4, with the depth of each notch 401 being less than half the length of the positioning block 4. The tapered ends facilitate docking between the positioning block 4 and the longitudinal beam 101, improving the ease of bed assembly. The notches 401 reduce the weight of the positioning block 4, lowering its material cost, and also facilitate its movement, further enhancing the ease of bed assembly.
[0030] Further improvements include, for example Figure 3 The support beam 102 has a U-shaped groove structure with its groove opening facing away from the crossbeam 103. Ribs 107 are provided at both ends and inside the support beam 102, with each rib 107 arranged at equal intervals along a first direction. Bolt holes 104 are provided on the top of the support beam 102 and on the ribs 107 at the ends of the support beam 102. The U-shaped groove structure of the support beam 102 can reduce its weight while maintaining its structural strength, thus achieving a lightweight design for the splicing section 1 and further improving its ease of transportation, movement, and assembly. The ribs 107 are used to further enhance the structural strength of the support beam 102. The bolt holes 104 on the ribs 107 at the ends are used to install bolt assemblies to achieve docking and fixing between the support beams 102. The screw holes 104 on the top of the support beam 102 are used to connect and fix with the guide rail 2, thereby improving the ease of bed splicing.
[0031] Further improvements include, for example Figure 2 and 4 The fastener 3 is located on the side of the longitudinal beam 101 near the crossbeam 103. The fastener 3 includes a screwing part 301 and two studs 303 fixed on the screwing part 301. The two studs 303 are coaxially arranged and have opposite thread directions. Nuts 302 are threaded onto both studs 303. A fastening seat 304 is fixedly connected to the end of the longitudinal beam 101. The fastening seat 304 has a slot 305 for the studs 303 to enter.
[0032] Fastener 3 can be used when splicing segment 1. In use, two studs 303 are respectively inserted into the slots 305 to connect the studs 303 to the two fastening seats 304 at the ends of the front and rear longitudinal beams 101 that need to be connected. The screwing part 301 has a hexagonal prism structure, which can be easily turned with a wrench to turn the studs 303. When the studs 303 rotate, the two nuts 302 can move closer or further apart along the studs 303. When the nuts 302 abut against the fastening seats 304... At that time, under the action of friction between the two, they can remain relatively stationary. Then, continue to turn the stud 302 to drive the two stationary seats 304 to move closer to each other, so that the two longitudinal beams 101 move closer to each other until the docking is completed. At this time, the two longitudinal beams 101 can be docked and fixed together by the fastener 3 and the positioning block 4. The fastener 3 can pull the two longitudinal beams 101 closer to each other and finally complete the docking, which can improve the convenience of docking of splicing section 1 and ultimately improve the convenience of splicing of laser cutting machine bed.
