[0027] In order to make the purpose, technical solution and effect of the present application clearer and more specific, the present application is further described in detail with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application. Without further description, the elements, structures and features in one embodiment can also be beneficially combined with other embodiments.

[0028] It should be noted that when a metastructure is referred to as being "fixed to" or "set on" another metastructure, it may be directly on the other metastructure or indirectly on the other metastructure. In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features.

[0029] The orientation or positional relationship indicated by terms such as "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" are based on the orientation or positional relationship shown in the drawings and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element structure referred to must have a specific orientation, be constructed and operate in a specific orientation.

[0030] See also Figure 1 The cutting machine bed provided in the present application includes a bed assembly, a connecting assembly and a supporting assembly. There are two bed assemblies, and the two bed assemblies are connected to each other through the connecting assembly. One or more supporting assemblies are respectively arranged at the bottom of the two bed assemblies.

[0031] Define the first direction as a preset horizontal direction, such as Figure 1 As shown, the two bed assemblies are spaced apart along the first direction. Since the bed assemblies are affected by their own gravity and the load they bear, and the combined force of the gravity and load borne by the bed assemblies usually deviates from the horizontal position of the feet, the two bed assemblies are prone to lateral deformation.

[0032] See also Figure 2 The support assembly includes a support base and two or more feet, the two or more feet are sequentially connected to the support base along a first direction, and the support base is connected to the bed assembly to support the bed assembly through the feet.

[0033] At this time, two or more feet can increase the support range of the bed assembly in the first direction. The combined force of gravity and load borne by each bed assembly will be located on the center line of two or more feet in the support assembly, and the combined force is perpendicular to the center line, so that the combined force is vertically and evenly transmitted to the ground through two or more feet, avoiding the lateral deformation of the bed assembly due to the deflection torque of the bed assembly.

[0034] Furthermore, since the bed assembly is subjected to only positive stress, the size of the connecting assembly can be reduced, thereby reducing the overall size of the cutting machine bed.

[0035] When a plurality of support assemblies are arranged at the bottom of the bed assembly, the plurality of support assemblies can be arranged at the bottom of the bed assembly in a desired arrangement, such as a straight line arrangement, an arc arrangement or a rectangular arrangement.

[0036] like Figure 1 As shown, the second direction is defined as a horizontal direction perpendicular to the first direction. In some embodiments, the bottoms of the two bed assemblies are respectively provided with a plurality of the support assemblies, and the plurality of support assemblies are sequentially arranged along the second direction.

[0037] In the actual setting process, the two bed assemblies are arranged in parallel along the second direction. The multiple support assemblies are arranged in sequence along the second direction, which can increase the support range of the bed assembly in the second direction, so that the bed assembly is evenly and stably supported.

[0038] The connection assembly is used to connect the two bed assemblies so that the two bed assemblies form a whole. Specifically, the connection assembly may include a connecting square tube, an exhaust connection pipe and a line connection pipe. The two ends of the connecting square tube are respectively fixedly connected to the two bed assemblies, the exhaust connection pipe communicates with the exhaust channels in the two bed assemblies, and the line connection pipe is used to pass wires, air pipes, water pipes and other lines. Of course, the connection assembly can also adopt other connection structures, which are not limited in this application.

[0039] In some embodiments, see Figure 3 and Figure 4 , the bed assembly includes the mounting base and exhaust pipe, please refer to Figure 5 The bed assembly also includes a support connector, a mounting seat is arranged on the top of the exhaust duct, the number of the support connectors is the same as that of the support assembly and they correspond one to one, the support connector is passed through the exhaust duct, the bottom end of the support connector passes through the exhaust duct and is connected to the corresponding support seat, and the top end of the support connector 13 passes through the exhaust duct and is connected to the mounting seat.

[0040] The mounting base is used for mounting various components, such as a driving platform, a cutting head, etc. An exhaust duct is formed inside the exhaust duct, and an exhaust port connected to the exhaust duct can be opened on the side of the exhaust duct facing another exhaust duct, so that after the exhaust duct is connected to an external exhaust device, cutting dust generated during the cutting process can be extracted through the exhaust port to avoid the diffusion of cutting dust.

[0041] The support connector is used to connect the mounting base and the support assembly to play a role in strengthening the support, and the load force on the mounting base can be directly transmitted to the support assembly through the support connector to improve the stability of the support. At this time, the exhaust pipe does not need to consider the problem of deformation due to force, and can be designed with a large diameter as needed.

[0042] Specifically, the supporting connector can be a tube, a rod, a block or other structures to achieve support and connection. For example, the supporting connector is a supporting connecting rod, and holes corresponding to the outer diameter of the supporting connecting rod are provided on the upper and lower surfaces of the exhaust pipe, so that the two ends of the supporting connecting rod pass through the corresponding holes and are welded to the mounting seat and the supporting seat.

[0043] See also Figure 6 In some embodiments, the support seat includes a mounting portion and a connecting portion, the connecting portion is connected to the mounting portion, the bottom end of the supporting connector passes through the exhaust pipe and is connected to the connecting portion, a gap is formed between the exhaust pipe and the mounting portion, the foot is detachably connected to the mounting portion, and the top end of the foot passes through the mounting portion and is located between the exhaust pipe and the mounting portion.

[0044] The mounting part is used to mount the foot, and the connecting part connects the supporting connector and the mounting part respectively, and forms a gap between the exhaust pipe and the mounting part to facilitate the removal of the foot. For example, the mounting part is provided with a fixing part, a first fixing hole is formed on the fixing part, and a second fixing hole is formed on the foot. When the foot passes through the mounting part and the second fixing hole is aligned with the first fixing hole, a pin can be inserted to fix the foot and the mounting part.

[0045] Alternatively, a mounting hole may be provided on the mounting portion, and a screw may be passed through the mounting hole and threadedly connected to the foot, so that the foot is fixedly connected to the mounting portion. Also, the detachable connection of the foot may be achieved by other means, which is not limited in this application.

[0046] In a further embodiment, the connecting portion may be enclosed by the foot, and the connecting portion is provided with an opening so that the foot can be installed or removed through the opening.

[0047] The connection part is enclosed in the foot, which can protect the foot, prevent the foot from being bumped during use, and reduce the pollution of the processing environment to the foot.

[0048] Specifically, the support assembly may include two feet, and the support seat includes two connecting parts, which are symmetrically arranged on the mounting part, each connecting part encloses a foot, and the opening of the connecting part faces the first direction, and the support connector is connected to the two connecting parts at the same time.

[0049] During the installation process, the first foot can be installed from the inner side of the bed assembly through the opening of the side connection part, and then the second foot can be installed from the outer side of the bed assembly through the opening of the side connection part. After the installation is completed, the combined force of the gravity and load borne by the bed assembly is located on the center line of the two feet, so that the bed assembly can be stably supported by the two feet, and the structure of the entire support assembly is simple and low-cost.

[0050] See also Figure 3 and Figure 5 In some embodiments, the bed assembly also includes two or more wiring pipes, which are arranged on the exhaust pipe in sequence along the second direction. The wiring pipe is provided with a wiring channel along the second direction, and is provided with two wiring openings connecting the two ends of the wiring channel. The bottom of the wiring pipe is connected to the supporting connector, and the top of the wiring pipe is connected to the mounting seat.

[0051] The wiring conduit is used to limit the lines of electric wires, gas lines, etc. Specifically, the lines of electric wires, gas lines, etc. can be sequentially passed through a plurality of wiring conduits, and come out from the wiring openings of the wiring conduits at appropriate positions and connected to corresponding devices.

[0052] In a further embodiment, the bed assembly also includes a partition, which is arranged on the exhaust duct and located on the side of the wiring duct close to another bed assembly, the bottom of the partition is connected to the supporting connector, and the top of the partition is connected to the mounting seat.

[0053] The opposite sides of the two bed assemblies form a cutting area, and the two partitions are used to separate the two sides of the cutting area to play a protective role.

[0054] In addition, the bed assembly also includes reinforcements, the number of which is the same as that of the supporting connectors and they correspond one to one. The reinforcements are arranged on the exhaust duct and are located on the side of the partition close to the other bed assembly. The reinforcements are respectively connected to the exhaust duct and the partition and are aligned with the connection between the corresponding supporting connector and the partition.

[0055] The reinforcement can increase the rigidity of the partition and avoid deformation of the partition during support, thereby playing a role in strengthening the support.

[0057] After the laser cutting machine is assembled, the combined force of gravity and load borne by the two bed components will be located on the center line of two or more feet in the support component, and the combined force is perpendicular to the center line, so that the combined force is vertically and evenly transmitted to the ground through two or more feet, avoiding lateral deformation of the bed component due to the deflection torque of the bed component.

[0058] In addition, the laser cutting machine provided in the embodiment of the present application also has the following advantages:

[0059] 1. The structure is simple and the cost is low. It only needs to add one or more sets of feet at the bottom of the bed assembly.

[0060] 2. The bed assembly has a strong load-bearing capacity, which greatly improves the rigidity of the heavy-load bed.

[0061] 3. Strong adaptability, which enhances the adaptability of the bed assembly to heavy loads, leaving ample redundant load space for the subsequent development of high-power and heavy-load models.
