Description

Technical Field

[0001] This utility model relates to the field of machine tools, and more specifically, to a machine tool base and a machine tool. Background Technology

[0002] In the field of modern machining, machine tools, as the core equipment for machining parts, directly affect the quality of industrial products and production efficiency. The machine tool base, as the fundamental structural component of the machine tool, directly influences its overall rigidity and stability through its internal structure and layout. In the machining of large and complex parts, machine tools must withstand higher cutting loads and dynamic impact forces, while also facing stringent requirements for chip removal efficiency. Therefore, optimizing the structural design of the machine tool base is crucial for improving the overall performance of the machine tool.

[0003] Currently, traditional machine tool bases mostly adopt simple box structures with a limited internal reinforcing rib layout, making it difficult to effectively distribute and resist the complex stresses during machining. While some bases do incorporate reinforcing ribs, these are often linear or grid-like, making them prone to localized deformation under combined vertical and lateral loads. This leads to decreased machine tool accuracy and affects workpiece machining quality. Furthermore, the chip removal system design of traditional bases is often inadequate, with scattered and irregularly shaped chip grooves. Chips tend to accumulate near the slide rails or inside the base, hindering normal table movement and potentially causing coolant leakage, corrosion of the base structure, and shortening the machine tool's lifespan.

[0031] The following disclosure provides many different implementation methods or examples for different solutions to implement this utility model.

[0032] On the one hand, such as Figures 1 to 3 As shown, this embodiment of the utility model provides a machine tool base. Figure 1As shown, the machine tool base includes a base body 1, with a rectangular structure 11 formed on the top of the base body 1. A slide rail is provided on the rectangular structure 11 along the front-to-back direction. Protrusions 2 are provided on both sides of the rear of the base body 1. The base body 1 is the basic support component of the machine tool base, bearing the weight of the machine tool and the machining load. The rectangular structure 11 formed on its top provides a mounting base for other components. The slide rail is mounted on the rectangular structure 11, providing support for the installation and movement of the worktable. The protrusions 2 on both sides of the rear of the base body 1 provide support for the installation of the machine tool column, forming a complete base bearing foundation.

[0033] The line connecting the two protrusions 2 forms a cross shape with the length of the slide rail, resulting in a more balanced stress distribution on the machine tool base after the machine tool column is installed. Simultaneously, the base body 1 contains a cross-shaped reinforcing rib structure 12, and the protrusions 2 contain a star-shaped reinforcing rib structure 21. During machining, the weight of the workpiece and worktable, as well as the cutting force generated during the cutting process, are transmitted through the worktable to the slide rail and rectangular structure 11, and further to the base body 1. The cross-shaped reinforcing rib structure 12 inside the base body 1 evenly distributes these loads across the entire base, enhancing its compressive strength. Simultaneously, the vertical pressure and lateral forces, such as the tool weight and cutting reaction force, borne by the machine tool column are transmitted to the base through the protrusions 2. The star-shaped reinforcing rib structure 21 within the protrusions 2 effectively disperses these vertical pressures and lateral forces, improving the stability of the machine tool column installation and reducing deformation of the base due to uneven stress. Therefore, the layout of the cross-shaped reinforcing rib structure 12 and the star-shaped reinforcing rib structure 21 can significantly improve the structural strength and rigidity of the machine tool base, enabling it to withstand larger cutting forces and workpiece weights, reduce the deformation of the base during processing, and improve the long-term stability and reliability of the machine tool.

[0034] like Figure 2 As shown, the base body 1 and the protrusion 2 are integrally formed. The interior of the base body 1 and the protrusion 2 is a hollow structure. A cross-shaped reinforcing rib structure 12 is set in the hollow structure of the base body 1, and a star-shaped reinforcing rib structure 21 is set in the hollow structure of the protrusion 2. The cross-shaped reinforcing rib structure 12 includes multiple horizontal ribs 121 and multiple vertical ribs 122. The star-shaped reinforcing rib structure 21 includes a central horizontal rib 211, a central vertical rib 212, and two diagonal ribs 213, forming an overall star-shaped structure. The central horizontal rib 211 of the star-shaped reinforcing rib structure 21 and one horizontal rib 121 of the cross-shaped reinforcing rib structure 12 are arranged along the same straight line, forming a continuous force transmission path through the base body 1 and the protrusion 2. When the machine tool column is subjected to a rightward cutting force, the central horizontal rib 211 of the star-shaped reinforcing rib structure 21 can partially transfer the force to the horizontal rib 121 of the cross-shaped reinforcing rib structure 12, which is collinear with it, thus preventing the force from accumulating locally in the protrusion 2.

[0035] like Figure 2 As shown, the cross-shaped reinforcing ribs 12 are arranged longitudinally and transversely within the cavity structure of the base body 1, while the star-shaped reinforcing ribs 21 are fully arranged within the cavity structure of the protrusion 2. When the machine tool is machining, the workpiece weight and cutting force carried by the worktable are transmitted to the base body 1 through the slide rails. The cross-shaped reinforcing ribs arranged longitudinally and transversely within the cavity structure of the base body 1 disperse these loads in various directions of the base body 1. At the same time, the tool weight and cutting reaction force borne by the machine tool column are transmitted through the protrusion 2, and the star-shaped reinforcing ribs 21 decompose the vertical pressure and lateral force in multiple directions.

[0036] Meanwhile, the two side horizontal ribs 25 surrounding the star-shaped reinforcing rib structure 21 and two horizontal ribs 121 of the cross-shaped reinforcing rib structure 12 are arranged along the same straight line. The central longitudinal rib 212 of the star-shaped reinforcing rib structure 21 and the longitudinal rib 122 of the cross-shaped reinforcing rib structure 12 are arranged parallel to each other, further enabling the star-shaped reinforcing rib structure 21 and the cross-shaped reinforcing rib structure 12 to form a coherent force transmission network. When the base body 1 or the protrusion 2 is subjected to force, the load can be smoothly transmitted between the two reinforcing rib structures, realizing the coordinated distribution of load by the two reinforcing rib structures, effectively reducing the stress in various parts of the base, and further improving the overall stability and structural strength of the base. For example, when the machine tool column transmits vertical pressure and lateral force to the protrusion 2, the two side horizontal ribs 25 surrounding the star-shaped reinforcing rib structure 21 can transmit part of the force to the horizontal ribs 211 of the cross-shaped reinforcing rib structure 12 that are collinear with it, reducing the resistance in the force transmission process and allowing the force to be quickly and evenly distributed to the entire base body 1.

[0037] like Figure 1 As shown, the slide rail includes multiple slide rail seats 13. A rectangular structure 11 is provided with a chip removal groove 14 along the front-to-back direction. The chip removal groove 14 is provided between the protrusion 2 and the slide rail seat 13 or between multiple slide rail seats 13 to form a continuous chip removal channel. It does not require additional space occupied by the base body, effectively utilizes the installation space, and realizes the combination of chip removal function and structural gap.

[0038] like Figure 3As shown, the protrusion 2 includes a first protrusion 22 and a second protrusion 23. The slide rail seat 13 includes a first slide rail seat 131 located on the left side of the rectangular structure 11 and a second slide rail seat 132 located on the right side of the rectangular structure 11. The chip removal groove 14 includes a first chip removal groove 141 and a second chip removal groove 142. The first chip removal groove 141 is located between the first protrusion 22 and the first slide rail seat 131, and the second chip removal groove 142 is located between the second protrusion 23 and the second slide rail seat 132. The parallel double-groove design of the first chip removal groove 141 and the second chip removal groove 142 can cope with machining environments with large chip volumes. At the same time, when the first chip removal groove 141 is blocked due to chip entanglement, the second chip removal groove 142 can still work normally and independently, avoiding machine tool downtime due to the failure of a single chip removal groove and improving the reliability of continuous machining of the machine tool.

[0039] like Figure 1 As shown, the chip removal groove 14 is a functional structure used to receive waste such as chips and coolant generated during the machining process from the machine tool base. The chip removal groove 14 has a V-shaped groove structure, which makes it easier for chips to gather at the bottom of the chip removal groove 14 under the action of gravity. The bottom of the V-shaped groove structure is set with an arc shape, which effectively reduces the chips remaining in the chip removal groove 14.

[0040] like Figure 3 As shown, the protrusion 2 is the basic structure of the machine tool base, and its top is used to install the machine tool column. The top of the protrusion 2 can also be provided with an annular groove 24 to collect chips and coolant falling from around the column. The groove 24 is connected to the chip removal groove 14, and the bottom surface of the groove 24 slopes downward from the side away from the chip removal groove 14 to the side closer to the chip removal groove 14, thereby forming a flow channel from the groove 24 to the chip removal groove 14. This has the function of guiding fluid or chips to the chip removal groove and preventing chips from accumulating at the bottom of the machine tool column.

[0041] like Figure 1 As shown, a rib 15 is provided at the connection between the side of the base body 1 and the side of the protrusion 2. The rib 15 is parallel to the horizontal plane, and the base body 1 and the protrusion 2 are laterally constrained by the addition of the rib 15. When the protrusion 2 is subjected to bending moment due to the force of the machine tool column, the rib 15 can effectively offset part of the moment by utilizing its tensile and compressive properties in the horizontal direction. At the same time, the load borne by the protrusion 2 can be distributed to a larger area of ​​the base body 1 through the rib 15, which significantly improves the stress distribution at the connection between the base body and the protrusion, avoids deformation caused by local stress concentration, and improves the overall rigidity and stability of the machine tool base.

[0042] On the other hand, this utility model also provides a machine tool. In some embodiments of this utility model, the machine tool includes a worktable, a machine tool column, and a machine tool base as described in one of the preceding embodiments. The worktable is slidably disposed on a slide rail, and the machine tool column is mounted on the protrusion 2.

[0043] In some embodiments, the machine tool further includes a crossbeam, and the machine tool column includes a first column and a second column, which are respectively disposed on two protrusions 2. The crossbeam is disposed on the first column and the second column, and the slide rail is disposed below the crossbeam along the front-rear direction of the base body 1. Since the machine tool has the aforementioned machine tool base, it also has the corresponding effects of the machine tool base, which will not be described in detail here.
