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.

Thus, statements such as "in one embodiment", "in some embodiments", "in other some embodiments", "in still other embodiments" etc. that appear in different places in this specification do not necessarily refer to the same embodiment, but mean "one or more but not all embodiments", unless otherwise specifically emphasized in other ways. In addition, in one or more embodiments, specific features, structures or characteristics may be combined in any suitable manner.

[0029] Laser cutting is to emit the laser from the laser and, through the optical path system, focus it into a laser beam with a high power density. The laser beam irradiates the surface of the workpiece, causing the workpiece to reach the melting point or boiling point. At the same time, the high-pressure gas coaxial with the beam blows away the melted or vaporized metal. As the relative position of the laser beam and the workpiece moves, a cut is finally formed on the workpiece, thus achieving the purpose of cutting.

[0030] In the actual use of a laser cutting machine, when the laser beam cuts the workpiece, the afterglow after piercing and the heat generated during processing will irradiate the machine tool bed or accessories below the workpiece. With the rapid development of the metal processing technology field, the power of the laser has become higher and higher, from the initial hundreds of watts to more than one hundred thousand watts now. When the laser beam of a high-power laser irradiates the machine tool bed, it will cause local thermal deformation or even burn-through of the machine tool bed, and the damaged machine tool bed will affect the cutting accuracy of the laser cutting machine.

[0031] To illustrate the technical solution of this application, the following will be described in conjunction with specific drawings and embodiments.

[0032] Please refer to Figure 1 , an embodiment of this application provides a machine tool bed, which includes a main bed 1 and a sub-bed 2. The end of the main bed 1 facing the first direction is used to carry the laser; the sub-bed 2 is arranged inside the main bed 1, the sub-bed 2 shields the inner side wall of the main bed 1, and there is a gap between the inner side wall of the main bed 1 and the sub-bed 2.

[0033] It should be noted that in a laser cutting machine, the workbench is placed on the machine tool bed, the laser is carried on the machine tool bed, the laser beam emitted by the laser can irradiate the workpiece placed on the workbench, and as the laser moves, the laser beam can form a cutting seam on the workpiece. The accuracy of the moving path of the laser is the main factor affecting the cutting accuracy of the laser cutting machine.

[0034] In the machine tool bed provided in the first aspect of the present application, the main bed 1 is used to support the laser. When the laser emits a laser beam, it can cut the workpiece placed on the machine tool bed. By arranging the auxiliary bed 2 independently provided relative to the main bed 1 inside the main bed 1, the auxiliary bed 2 shields the inner side wall of the main bed 1, so as to prevent the laser beam emitted by the laser from directly irradiating the main bed 1, which can prevent the main bed 1 from being damaged and will not affect the accuracy of the moving path of the laser. Therefore, after the auxiliary bed 2 in the machine tool bed provided by the application embodiment is locally heated and deformed or even burned through, the main bed 1 will not be damaged, which can ensure the accuracy of the moving path of the laser and solve the technical problem that the damaged machine tool bed will affect the cutting accuracy of the laser cutting machine.

[0035] Please refer to Figure 1 , in some embodiments, the main bed 1 includes a first support member 11 and a second support member 12, and the first support member 11 and the second support member 12 are arranged opposite to each other; the auxiliary bed 2 includes a first shielding member 21 and a second shielding member 22. Both the first shielding member 21 and the second shielding member 22 are located between the first support member 11 and the second support member 12, and the first shielding member 21 shields the surface of the first support member 11 facing the second support member 12, and the second shielding member 22 shields the surface of the second support member 12 facing the first support member 11.

[0036] It should be noted that the first direction is the Z direction in the figure. A guide rail is provided at the end of the main bed 1 facing the Z direction, and the laser is slidably arranged on the slide rail. The laser beam emitted by the laser is emitted in the direction opposite to the Z direction and irradiates the workpiece, and the laser beam will also irradiate the inner side wall of the machine tool bed.

[0037] In the above embodiment, the side wall of the first shielding member 21 facing away from the first support member 11 and the side wall of the second shielding member 22 facing away from the second support member 12 are the inner side walls of the machine tool bed. When the laser is working, the first shielding member 21 and the second shielding member 22 will shield the laser beam to prevent the laser beam from irradiating the first support member 11 and the second support member 12, so as to prevent the main bed 1 from being damaged, which will not affect the guiding direction of the guide rail on the main bed 1, nor will it affect the distance between the first support member 11 and the second support member 12, so that the laser sliding on the main bed 1 can accurately move along the predetermined path.

[0038] In addition, in the above embodiment, there is a gap between the first support member 11 and the second support member 12. When the workbench is set on the machine tool bed, the side of the workbench away from the Z direction is hollowed out, which facilitates the placement of the waste collection device on the side of the workbench away from the Z direction, so as to collect waste generated when cutting the workpiece on the workbench.

[0039] Please refer to Figure 1 In some embodiments, the main bed 1 further includes a first connecting member 13 , which is located between the first support member 11 and the second support member 12 , and both ends of the first connecting member 13 are connected to the first support member 11 and the second support member 12 , respectively.

[0040] In the above embodiment, the two ends of the first connecting member 13 are respectively connected to the first support member 11 and the second support member 12. The first connecting member 13 can support the first support member 11 and the second support member 12 to enhance the structural stability of the main bed 1 and prevent the first support member 11 and the second support member 12 from tipping over, thereby not affecting the guiding direction of the guide rail on the main bed 1, nor affecting the distance between the first support member 11 and the second support member 12, so that the laser sliding on the main bed 1 can move accurately along the predetermined path.

[0041] Furthermore, the first connecting member 13 is located between the first supporting member 11 and the second supporting member 12 , which can prevent the first connecting member 13 from occupying additional space, thereby making the structure of the main bed 1 more compact.

[0042] Please refer to Figure 1 In the above embodiment, the first support member 11 and the second support member 12 are spaced apart in the Y direction in the figure. A plurality of first connecting members 13 are provided, and the plurality of first connecting members 13 are spaced apart in the X direction in the figure, and the X direction, the Y direction, and the Z direction are perpendicular to each other.

[0043] It is understood that in the above embodiment, the auxiliary bed 2 needs to be placed between the first support member 11 and the second support member 12 in a direction opposite to the Z direction. Since the first connecting member 13 is located between the first support member 11 and the second support member 12, the first connecting member 13 will resist the auxiliary bed 2 when the auxiliary bed 2 is placed between the first support member 11 and the second support member 12.

[0044] Please refer to Figure 1 and Figure 2 In some embodiments, a avoidance groove 221 is provided on the first shielding member 21 and the second shielding member 22. The avoidance groove 221 passes through in the distribution direction of the first support member 11 and the second support member 12, and the groove opening of the avoidance groove 221 is opposite to the first direction (Z direction). The first connecting member 13 is accommodated in the avoidance groove 221 through the groove opening of the avoidance groove 221.

[0045] With the above settings, when the auxiliary bed body 2 is placed between the first support member 11 and the second support member 12, the avoidance through slot 221 is aligned with the first connecting member 13 to prevent the first connecting member 13 from blocking the first shielding member 21 and the second shielding member 22.

[0046] And please refer to Figure 1 , with the above settings, the first support member 11 and the second support member 12 can shield more of the inner wall of the main bed body 1 to reduce the influence of the laser beam on the main bed body 1 and mitigate the damage to the main bed body 1.

[0047] Please refer to Figure 2 , in some embodiments, air ducts (not shown in the figure) and air inlets 211 communicating with the air ducts are provided on both the first shielding member 21 and the second shielding member 22. The air inlet 211 on the first shielding member 21 faces the second shielding member 22, and the air inlet 211 on the second shielding member 22 faces the first shielding member 21.

[0048] In the above embodiment, the air inlet 211 on the first shielding member 21 and the air inlet 211 on the second shielding member 22 are both in communication with the space between the first shielding member 21 and the second shielding member 22. The air duct can be in communication with an air extraction system or a blowing system to form flowing air in the air duct on the first shielding member 21, the air duct on the second shielding member 22, and the space between the first shielding member 21 and the second shielding member 22. The air flow can carry away the heat on the machine tool bed body to reduce the temperature of the machine tool bed body and prevent the machine tool bed body from being deformed due to excessive temperature.

[0049] Please refer to Figure 2 , in some embodiments, the air inlets 211 on the first shielding member 21 and the air inlets 211 on the second shielding member 22 are arranged in one-to-one correspondence.

The second connecting member 23 is located between the first shielding member 21 and the second shielding member 22, and both ends of the second connecting member 23 are respectively connected to the first shielding member 21 and the second shielding member 22.

[0052] In the above embodiment, both ends of the second connecting member 23 are respectively connected to the first shielding member 21 and the second shielding member 22. The second connecting member 23 can support the first shielding member 21 and the second shielding member 22 to enhance the structural stability of the auxiliary bed body 2.

[0053] In some embodiments, the workbench is set on the auxiliary bed 2, and the second connecting member 23 can support the first shielding member 21 and the second shielding member 22 to prevent the first shielding member 21 and the second shielding member 22 from tipping over, thereby not affecting the position of the workpiece on the workbench, so that a cutting seam can be formed at a preset position of the workpiece, thereby not affecting the cutting accuracy of the laser cutting machine.

[0054] Furthermore, in the above embodiment, the second connecting member 23 is located between the first shielding member 21 and the second shielding member 22 , which can prevent the second connecting member 23 from occupying additional space, thereby making the structure of the auxiliary bed 2 more compact.
