[0029] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0030] Embodiment 1

[0031] This embodiment provides a machine tool bed 100, such as Figure 1 to Figure 5 As shown, it includes a first side support 1, a second side support 3 and a base frame 2; the first side support 1 and the second side support 3 are arranged opposite to each other, and the bottom end of the first side support 1 is fixedly connected to one end of the base frame 2, and the bottom end of the second side support 3 is fixedly connected to the other end of the base frame 2; the first side support 1, the base frame 2 and the second side support 3 are integrally formed; the first side support 1 has a first cavity, the second side support 3 has a second cavity, and transverse ribs 4 and longitudinal ribs 5 are fixedly arranged in the first cavity and the second cavity; the lower end of the first side support 1 on the side close to the second side support 3 extends obliquely toward the side close to the second side support 3; and the lower end of the second side support 3 on the side close to the first side support 1 extends obliquely toward the side close to the first side support 1.

[0032] By adopting a first side support 1 and a second side support 3 with a transverse rib plate 4 and a longitudinal rib plate 5 inside, and adopting an integral molding method, and the bottom of the first side support 1 and the second side support 3 is set as a wide bottom structure, it provides greater rigid support for various devices installed on the machine tool bed 100, and increases the overall strength of the machine tool bed 100; thereby reducing the resonance phenomenon and ensuring that the cutting accuracy is not affected.

[0033] Specifically, the first side support 1, the base frame 2 and the second side support 3 are integrally cast.

[0034] Specifically, a sand casting process is adopted, and three-dimensional software is used to reasonably distribute the transverse ribs 4 and the longitudinal ribs 5 on the stressed longitudinal cross-section and the stressed transverse cross-section of the machine tool bed 100. Finite element static stress analysis, accurate material calculation and precise design are used to solve the problems of insufficient rigidity and resonance of the original bed welded with multiple bracket steel structures, which affect the cutting accuracy.

[0035] Specifically, the overall dimensions formed by the first side support 1, the base frame 2 and the second side support 3 are determined by the standard model dimensions of the X / Y / Z three-axis CNC gantry machine tool, and the machine tool travel parameters are: X-axis 1000mm, Y-axis 800mm, Z-axis 500mm, which can meet a wide range of customer needs.

[0036] Specifically, the machine tool bed 100 of the present embodiment is a combination of a workbench unit (base frame 2) and two bridge seat units (first side support 1 and second side support 3), and large inverted eight-shaped oblique ribs are added (the lower end of the first side support 1 close to the second side support 3 and the lower end of the second side support 3 close to the first side support 1). At the same time, the transverse ribs 4 and the longitudinal ribs 5 inside the first side support 1 and the second side support 3 are strictly distributed, which not only enhances the strength of the integrally cast machine tool bed 100, but also opens weight-reducing holes at various positions to reduce its own weight, thereby meeting the parameter requirements of high-efficiency CNC laser cutting equipment that can travel at 100 m / min.

[0037] In the optional scheme of this embodiment, it is more preferred that the material of the first side support 1, the base frame 2 and the second side support 3 is HT300 gray cast iron.

[0040] Among the optional solutions of this embodiment, it is more preferred that Figure 1 to Figure 5 As shown, a waste recovery channel 7 is provided on the first side support 1 and the base frame 2. The waste recovery channel 7 provides an accommodating space for waste recovery equipment.

[0041] Among the optional solutions of this embodiment, it is more preferred that Figure 1 to Figure 5 As shown, the upper ends of the first side support 1 and the second side support 3 are both provided with a guide rail connection surface 8. The provision of the guide rail connection surface 8 can provide a plane for guide rail installation, facilitating the installation and use of the guide rail.

[0042] Specifically, the setting of the guide rail connecting surface 8 is the core area to ensure the accuracy of the machine tool, and it undergoes processes such as rough machining, quenching, and fine grinding.

[0043] Among the optional solutions of this embodiment, it is more preferred that Figure 1 to Figure 5 As shown, a plurality of horizontal plane anchor holes 9 are provided on the lower surface of the base frame 2, and the horizontal plane anchor holes 9 are used to fix the horizontal plane anchors. The provision of the horizontal plane anchor holes 9 can provide an installation position for the horizontal plane anchors, ensuring the stable placement of the machine tool bed 100.

[0044] Among the optional solutions of this embodiment, it is more preferred that Figure 1 to Figure 5 As shown, the first side support 1, the base frame 2 and the second side support 3 are all provided with an equipment installation plane 10. The setting of the equipment installation plane 10 facilitates the stable and fixed installation of the external sheet metal, the machine tool electrical control cabinet, etc.

[0045] Specifically, a boss is left around the whole formed by the first side support 1, the base frame 2 and the second side support 3, and the boss has an equipment installation plane 10, which can be stably and firmly installed with external sheet metal, machine tool electrical control cabinet, etc. after rough processing.
