Description

Technical Field

[0001] This utility model relates to the field of machine tool equipment technology, specifically to a stable base structure for a CNC heavy cutting machine. Background Technology

[0002] Heavy-duty cutting machines are industrial equipment specifically designed for machining large, high-hardness, or complex workpieces. During actual operation, they must withstand large cutting forces and heavy-duty workpieces, and require extremely high vibration resistance and stability to ensure no deformation during machining. The base, as the main load-bearing component of a heavy-duty cutting machine, has a significant impact on its operational stability. Currently, to enhance strength, the bases of existing heavy-duty cutting machines are generally made of cast iron or cast steel. While using solid cast iron or cast steel structures can increase the base's strength, it not only makes the base very heavy but also significantly increases the equipment cost. Therefore, how to achieve good strength and stability in the base through structural design while reducing its weight and cost is a technical problem that needs to be solved in this field. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model proposes a stable base structure for a CNC heavy cutting machine. Through the structural design of the internal reinforcing ribs and supporting surfaces of the base, it presents a triangular stable structure. The base has internal openings and rounded corners to reduce weight and stress accumulation, thereby maximizing the strength and stability of the base while reducing weight.

[0004] To achieve the above technical solution, this utility model provides a stable base structure for a CNC heavy cutting machine, comprising: a base body, the base body including a bottom frame and an irregular support surface integrally disposed on the top of the bottom frame, the support surface including a flat surface located at the center of the top of the bottom frame, the flat surface being connected to the bottom frame by a vertical reinforcing rib disposed below the center of the bottom of the flat surface, the flat surface having upwardly protruding protrusions on both the left and right sides, and a downwardly inclined lower surface on the other side of the protrusions, and an arc-shaped lower surface on the other side of the downward inclined lower surface. The base has a curved connecting surface, with an inclined top on the other side. The other end of the inclined top is connected to the end edge of the base frame. The top of the first inclined reinforcing rib is connected to the bottom surface of the intersection between the flat surface and the protruding surface. The bottom surface of the first inclined reinforcing rib is connected to the base frame. The top of the second inclined reinforcing rib is connected to the top center of the inclined bottom. The bottom of the second inclined reinforcing rib is connected to the base frame. The top of the third inclined reinforcing rib is connected to the bottom surface of the intersection between the curved connecting surface and the inclined top. The bottom of the third inclined reinforcing rib is connected to the base frame. The base body has multiple hollow holes.

[0005] In the above technical solution, the top surface of the base body is designed as an irregular support surface, consisting of a flat surface, a raised surface, a sloping lower surface, an arc-shaped connecting surface, and a sloping upper surface. This meets the installation requirements of components such as the gantry, moving worktable, and tool magazine of heavy-duty cutting machines. Vertical reinforcing ribs, first oblique reinforcing ribs, second oblique reinforcing ribs, and third oblique reinforcing ribs are added according to the stress conditions of different surfaces. This creates an angle between the internal reinforcing ribs and the support surface, presenting a triangular stable structure. Furthermore, the staggered distribution of reinforcing ribs enhances the strength of the support surface. Simultaneously, by incorporating perforations within the base body, the weight of the base can be effectively reduced. Combined with the structural design of the reinforcing ribs, the strength and stability of the base can be maximized while reducing weight.

[0006] Preferably, a Y-axis guide rail mounting groove is provided on the raised surface of the base body along the Y direction to facilitate the docking of the base body with the mobile platform.

[0007] Preferably, a guide rod mounting seat and a limiting block are installed on the flat surface of the base body. In actual installation, the guide rod mounting seat is used to connect with the guide rod of the mobile platform to regulate the movement of the mobile platform in the Y direction.

[0008] Preferably, the arc-shaped connecting surface of the base body is provided with a Y-direction lead screw mounting groove arranged along the Y direction. In actual installation, the Y-direction lead screw mounting groove is used to install the Y-direction drive shaft that drives the moving platform.

[0009] Preferably, the upper left and upper right corners of the base body are provided with gantry support blocks to facilitate quick positioning and installation of the gantry.

[0010] Preferably, the bottom edge of the base body is provided with multiple foot pad mounting bases to facilitate the alignment and installation of the base body.

[0011] The beneficial effects of the stable base structure for a CNC heavy-duty cutting machine provided by this utility model are as follows: The stable base structure of this CNC heavy-duty cutting machine is ingeniously designed. By setting the top surface of the base body as an irregular support surface, the support surface is composed of a flat surface, a raised surface, a sloping lower surface, an arc-shaped connecting surface, and a sloping upper surface, to meet the installation requirements of components such as the gantry, moving worktable, and tool magazine of the heavy-duty cutting machine. Furthermore, vertical reinforcing ribs, first oblique reinforcing ribs, second oblique reinforcing ribs, and third oblique reinforcing ribs are set according to the stress conditions of different surfaces, so that the reinforcing ribs inside the base body form an angle with the support surface, presenting a triangular stable structure. Moreover, the staggered distribution of reinforcing ribs can enhance the strength of the support surface. At the same time, by setting hollow holes in the base body, the weight of the base can be effectively reduced, and in conjunction with the structural design of the reinforcing ribs, the strength and stability of the base can be maximized while reducing weight.
