[0002] A gantry machining center is a high-performance CNC machine tool designed specifically for machining large or complex workpieces.

[0003] Currently, most gantry machining centers have separate and independent base and worktable structures. Therefore, they need to be disassembled into individual parts before shipment and then transported. This also makes hoisting inconvenient and causes problems with chip removal. Utility Model Content

[0022] To further illustrate the various embodiments, the present invention provides accompanying drawings. These drawings are part of the disclosure of the present invention and are mainly used to illustrate the embodiments, and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these drawings, those skilled in the art should be able to understand other possible implementations and the advantages of the present invention. The components in the drawings are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0023] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0024] Example 1

[0025] Reference Figures 1 to 4 Embodiment 1 provides a base structure for a machine tool (hereinafter referred to as the base structure) to simultaneously replace the separate bases and worktables of CNC machine tools in the prior art.

[0026] like Figure 1, Figure 3 and Figure 4 As shown, the base structure 100 of this embodiment includes a first support part 1, a second support part 2, and a workbench part 3 connected between the first support part 1 and the second support part 2, with the first support part 1 on the left side of the workbench part 3 and the second support part 2 on the right side of the workbench part 3.

[0027] The first support section 1, the second support section 2, and the worktable section 3 are connected to form an integrated structure.

[0028] The first support part 1 is inclined to the upper left relative to the worktable part 3, and the second support part 2 is inclined to the upper right relative to the worktable part 3. The first support part 1 and the second support part 2 are respectively used to support the two columns of the gantry 4 of the machine tool.

[0029] The upper surface of the connection between the first support part 1 and the second support part 2 and the worktable part 3 is provided with a groove 5. The first support part 1 and the second support part 2 are provided with multiple chip removal channels 6 that penetrate their inner and outer surfaces. The chip removal channels 6 on each side are arranged side by side at intervals, and each chip removal channel 6 is connected to the corresponding groove 5.

[0030] In this embodiment, the first support part 1, the second support part 2, and the workbench part 3 are integrated into a single structure through an integral casting process. Therefore, compared with the total weight of the base and workbench designed separately in the prior art, the total weight of the base structure 100 in this embodiment is reduced by 30%, making it lighter.

[0031] During the machining process of the workpiece, the chips generated will flow into the chip removal channels 6 through the grooves 5 on the left and right sides, and then be discharged from the chip removal channels 6. This can prevent the chips from accumulating on the base structure 100 of this embodiment. Therefore, compared with the prior art, the base structure 100 of this embodiment has a better chip removal effect.

[0032] More specifically, such as Figure 2 As shown, the workbench 3 includes a workbench surface 31 and a bottom surface 32 arranged on the top and bottom, and a rigid support frame 33 connected between the workbench surface 31 and the bottom surface 32. The rigid support frame 33 includes a plurality of reinforcing ribs 331 arranged at intervals to form a rigid support structure. The workbench surface 31 has a T-shaped groove 311.

[0033] By connecting the first support part 1, the second support part 2 and the worktable part 3 to form an integrated structure, the base of the machine tool and the worktable are set as an integrated structure, and during workpiece processing, smooth chip removal is achieved through the chip removal channel 6 of the first support part 1 and the second support part 2.

[0034] Of course, in other embodiments, the first support part 1, the second support part 2 and the worktable part 3 are connected to form an integral connection structure, such as by screws, bolts or welding, but this will have a certain adverse effect on the machining accuracy of the machine tool.

[0035] Alternatively, a chip removal channel 6 can be separately provided in the first support part 1 or the second support part 2, while the other support part does not have a chip removal channel 6. However, the chip removal effect of a chip removal channel 6 on only one side is not as good as that of a chip removal channel 6 on both sides.

[0036] In another preferred embodiment, such as Figure 2 As shown, the inclination angle A of the inner wall surface 61 of each chip removal channel 6 near the workbench 3 is 35 degrees to ensure smoother discharge of chips from the chip removal channel 6.

[0037] Further preferred, such as Figure 1 As shown, the front and rear surfaces of the workbench 3 are each provided with multiple lifting holes 7, and the lifting holes 7 are circular to facilitate lifting operations.

[0038] When hoisting the base structure 100 of this embodiment, the edge of the hoisting hole 7 is provided with a large rounded corner to prevent the hoisting strap from being damaged.

[0039] Of course, in other embodiments, the lifting hole 7 may also be square or other shapes.

[0040] Example 2

[0041] Embodiment 2 provides a machine tool, which includes at least the base structure 100 of Embodiment 1.

[0042] Although the present invention has been specifically shown and described in conjunction with preferred embodiments, those skilled in the art should understand that various changes in form and detail may be made to the present invention without departing from the spirit and scope of the present invention as defined in the appended claims, and all such changes shall be within the scope of protection of the present invention.
