Description

Technical Field

[0001] This utility model belongs to the field of base technology, specifically relating to a high-toughness base for machine tools. Background Technology

[0002] The CNC machine tool base is the fundamental component of a CNC machine tool, serving as the installation foundation and reference for other parts. Equivalent to the bed of a CNC lathe, the CNC machine tool base mainly consists of base longitudinal beams, base plates, adjusting level supports, leveling nuts, and fastening screws. The weight and size range of CNC machine tool bases are quite wide, with lengths ranging from a few millimeters to tens of meters, meeting the requirements of various industrial sectors and thus enjoying widespread use.

[0003] One weakness of traditional cast iron bases is their brittleness. When subjected to accidental overload or impact, they are prone to cracking or even sudden breakage, leading to the scrapping of the entire machine. In order to ensure the toughness of the base, it is usually made of high-strength and tough tempered steel forging, which makes the overall base relatively heavy. Utility Model Content

[0004] In view of the shortcomings of the prior art, the technical problem to be solved by this utility model is to provide a high toughness base for machine tools, which can provide high toughness and reduce the weight of the base.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a high-toughness base for machine tools, comprising a base body, wherein a cavity is formed by hollowing out the base body, and a plurality of first support plates and a plurality of second support plates are arranged crosswise in the cavity, wherein rectangular grooves are provided on the first support plates and the second support plates, and the four feet of the rectangular grooves are rounded.

[0006] The surfaces of the first and second support plates are provided with mesh-like reinforcing ribs.

[0007] A cavity is formed between the two first support plates and between the two second support plates, and a through hole is provided at the bottom of the base body corresponding to the position of the rectangular cavity.

[0008] The bottom of the base body is provided with a high-density polyethylene pad.

[0009] The base body is provided with a flow guide groove.

[0010] The two sides of the guide channel are connected to inclined channels, and a guide channel with a lower center and lower sides is provided between the two inclined channels.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] This utility model discloses a high-toughness base for machine tools. Multiple first and second support plates are used to support the base and ensure its strength. Rectangular grooves are incorporated to reduce the weight of the base, and rounded inner corners facilitate smooth force transmission, eliminating stress peaks. This effectively prevents fatigue cracks and sudden fractures in parts under alternating loads, significantly improving product reliability and lifespan. It also addresses the root cause of stress concentration at sharp corners and the problem of drastically reducing the effective fatigue strength and impact toughness of the structure.

[0017] To make the above-mentioned features and advantages of this utility model more apparent and understandable, specific embodiments are described below in conjunction with the accompanying drawings for detailed explanation.

[0018] like Figures 1-3 As shown, this embodiment provides a high-toughness base for machine tools, including a base body 1. The base body 1 has a hollow cavity formed inside. Multiple first support plates 2 and multiple second support plates 3 are arranged intersectingly within the cavity. Rectangular grooves 4 are formed on both the first and second support plates 2, with rounded corners 5 at the four ends. Specifically, the surfaces of the first and second support plates 2 and 3 are provided with mesh-like reinforcing ribs 6. The mesh-like reinforcing ribs 6 further enhance the strength of the base. By providing multiple first support plates 2 and multiple second support plates 3 to support the base and ensure its strength, and by providing rectangular grooves 4 to reduce the weight of the base, and by using rounded corners 5 for smooth force transmission, stress peaks are eliminated. This effectively prevents fatigue cracks and sudden fractures of parts under alternating loads, significantly improving product reliability and lifespan, solving the root cause of stress concentration at sharp corners, and addressing the problem of greatly reducing the effective fatigue strength and impact toughness of the structure.

[0019] Furthermore, a cavity is formed between the two first support plates 2 and the two second support plates 3, and a through hole is provided at the bottom of the base body 1 corresponding to the position of the rectangular cavity. The through hole further reduces the weight of the base.

[0020] Furthermore, a high-density polyethylene pad 7 is provided at the bottom of the base body 1. This serves to reduce shock and prevent slippage.

[0021] Furthermore, the base body 1 is provided with a flow guide trough 8. Specifically, inclined grooves 9 are connected to both sides of the flow guide trough 8, and a flow channel 10 with a lower center and lower sides is provided between the two inclined grooves 9. The flow channel 10 and the two inclined grooves 9 work together to stably transfer the cooling water to the flow guide trough 8 for output.
