[0031] During the transportation of the laser cutting machine, the entire laser cutting machine needs to be placed on a transport vehicle. In order to improve the stability of the laser cutting machine, the chassis base also needs to be clamped on the fixed beam of the transport vehicle. Due to the usual bumps during transportation, the chassis base is prone to collide with the fixed beam, causing damage to the chassis base. In addition, the laser cutting machine is usually placed in a workshop for cutting, and is generally equipped with an AVG cart or other automatic transport device in conjunction with a manipulator to achieve automatic loading and unloading. However, in the actual production process, due to machine failure and other reasons, the transport device collides with the laser cutting machine, causing damage to the body of the laser cutting machine. In response to the above problems, the present application proposes the following embodiments.

[0032] Example

[0033] This embodiment discloses a chassis base, please refer to Figures 1 to 6 As shown, the chassis base includes:

[0034] A bottom plate 10, wherein a plurality of pads 11 are arranged at the lower edge of the bottom plate 10;

[0035] The first anti-collision mechanism 20 is fixed to the cushion block 11 and has a rocker plate 21 extending toward the outside of the bottom plate 10;

[0036] The second anti-collision mechanism 30 is fixed to the cushion block 11 and has an anti-collision plate 31 facing the inner side of the bottom plate 10 . A gap 32 for anti-collision and buffering is defined between the anti-collision plate 31 and the cushion block 11 .

[0037] The chassis base of the present embodiment can be applied to a laser cutting machine as a supporting platform for a Y-axis driving device, a gantry, etc. A first anti-collision mechanism 20 and a second anti-collision mechanism 30 are arranged on the cushion block 11. The first anti-collision mechanism 20 has a seesaw 21 extending toward the outside of the base plate 10. Through the blocking effect of the seesaw 21, it is possible to prevent the transport device, etc. from directly hitting the body of the laser cutting machine, thereby providing good anti-collision protection; the second anti-collision mechanism 30 has an anti-collision plate 31 facing the inside of the base plate 10. The anti-collision plate 31 can be made of a material with a certain elasticity. Through the blocking effect of the anti-collision plate 31, during transportation, it is possible to prevent the fixed beam of the transport vehicle from directly hitting the cushion block 11, thereby providing good anti-collision protection function. Moreover, there is an anti-collision buffer gap 32 between the anti-collision plate 31 and the cushion block 11, so that the anti-collision plate 31 has a certain deformation buffer space when hit, thereby further improving the anti-collision ability of the chassis base.

[0038] It should be noted that the bottom plate 10 used in this embodiment has a cubic structure. Based on the bottom plate 10 with a cubic structure, in order to improve the stability of the chassis base after being placed, this embodiment has four pads 11, which are respectively arranged at the four corners of the lower end of the bottom plate 10. The lower end here is Figure 1 and Figure 2 In the description, it refers to one end along the z direction, which is only for the convenience of describing the structure of the base plate 10 and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation.

[0039] It should be noted that in other embodiments, the number of pads 11 can also be set to three, six, eight, etc., and are respectively arranged at various positions at the lower end of the base plate 10 according to the force distribution. The number and distribution positions are not limited to the number and distribution positions mentioned in this embodiment. These equivalent variations or replacements are all included in the scope defined by the claims of the invention.

[0040] Please refer to Figure 2 As shown, the first anti-collision mechanism 20 of the present embodiment also has a first mounting portion 22, and the first mounting portion 22 is fixedly connected to the cushion block 11. Specifically, the first mounting portion 22 is mounted on the cushion block 11 by bolt fixing, which is convenient for assembly and replacement. The rocker 21 is connected to one end of the first mounting portion 22 and is inclined with respect to the first mounting portion 22. The inclined design makes the rocker 21 tilt outward after the first mounting portion 22 is installed, thereby improving the elastic buffering effect of the rocker 21. The rocker 21 and the first mounting portion 22 are both made of plastic material and have a certain elasticity, thereby further improving their elastic buffering effect. Moreover, the two are made by integrated molding, which simplifies the structure and reduces the difficulty of production. The four rockers 21 all extend toward the outside of the bottom plate 10, which can effectively provide anti-collision protection for the chassis base in two directions.

[0041] To facilitate the transportation and fixing of the laser cutting machine, please refer to Figure 2 As shown, the seesaw 21 of this embodiment is provided with a through hole 211 for bundling. Before transporting the laser cutting machine, a bundling rope can be passed through the through hole 211 and then tied to the fixed beam of the transport vehicle to prevent the laser cutting machine from loosening.

[0042] It should be noted that the number of through holes 211 used in this embodiment is one, but is not limited to one. It can be specifically designed according to the position and number of the fixed beams of the transport vehicle. In other embodiments, the same rocker 21 can be provided with multiple through holes 211, and then they are bound and fixed accordingly to ensure that the laser cutting machine does not loosen.

[0043] Please refer to Figure 2 As shown, the second anti-collision mechanism 30 of the present embodiment also has a second mounting portion 33, and the second mounting portion 33 is fixedly connected to the cushion block 11. Specifically, the second mounting portion 33 is mounted on the cushion block 11 by bolt fixing, which is convenient for assembly and replacement. The anti-collision plate 31 is connected to one end of the second mounting portion 33 and is perpendicular to the second mounting portion 33. The two form a "concave" structure, which is stuck in the periphery of the cushion block 11 during installation, and has a high degree of fit; the anti-collision plate 31 and the second mounting portion 33 are both made of plastic material and have a certain elasticity, and the two are made by integrated molding, which simplifies the structure and reduces the difficulty of production.

[0044] When transporting and fixing the laser cutting machine, in order to prevent the bottom plate 10 from directly colliding with the crossbeam of the transport vehicle, please refer to Figure 2 , Figure 4 and Figure 6 As shown, in this embodiment, two anti-collision strips 12 arranged along the y direction are further provided at the lower end of the base plate 10. The two anti-collision strips 12 are both installed at the lower end of the base plate 10 by bolts, which is convenient for assembly and replacement.

[0045] Please refer to Figure 3 and Figure 4 As shown, an adjustable support foot 13 is provided at the bottom of the cushion block 11, and a plurality of adjustable support feet 13 can be used to adjust the level of the chassis base when used in combination.

[0046] Since the laser cutting machine has many parts and a heavy body, in order to prevent the middle of the bottom plate 10 from being deformed due to excessive force, please refer to Figure 1 and Figure 3 As shown, a support block 14 is provided between the two pads 11 along the y direction. The support block 14 serves as a supporting component in the middle of the edge of the base plate 10, which can well support the base plate 10 and prevent the base plate 10 from deforming. An adjustable support foot 13 is provided on the support block 14 for adjusting the level of the chassis base.

[0047] A dust collection device is usually provided at the top of the laser cutting machine. The dust generated after cutting is collected in the dust collection device and then transported to the dust treatment device through a pipe. In order to arrange the pipe more reasonably, this embodiment provides a through hole 15 for the pipe to pass through on the bottom plate 10. The pipe can pass downward through the bottom plate 10 so that the pipe is hidden at the bottom of the laser cutting machine, making the structure of the entire device more compact.

[0048] A y-axis driving device and a gantry that can move along the y-direction are usually installed on the upper end of the laser cutting machine. A plurality of mounting holes 16 for installation are provided on the bottom plate 10 for easy installation.
