Description

Technical Field

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

[0002] Heavy-duty cutting machines are industrial equipment specifically designed for machining large, high-hardness, or complex workpieces. They possess large-size machining capabilities, with worktables ranging from several meters to tens of meters in size, making them suitable for processing large workpieces. Due to their large span and heavy load, the worktable surfaces of heavy-duty cutting machines experience varying stresses, especially in four-spindle machines. Each spindle may process different equipment and perform different machining operations, leading to uneven stress on the worktable surface. This makes the worktable prone to bending and deformation, which can affect the accuracy of heavy-duty machining operations performed simultaneously by multiple spindles. Therefore, improvements are needed. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model proposes a worktable structure for a CNC multi-spindle heavy cutting machine. By installing a cross-shaped reinforcing rib plate at the bottom of the worktable and designing the structure of the cross-shaped reinforcing rib plate, the stress on the surface of the worktable can be evenly distributed, thereby improving rigidity and meeting the requirements of heavy cutting machining performed by multiple spindles simultaneously.

[0004] To achieve the above technical solution, this utility model provides a worktable structure for a CNC multi-spindle heavy cutting machine, comprising: a worktable, the bottom of which is provided with a cross-shaped reinforcing rib plate supporting the entire worktable, the cross-shaped reinforcing rib plate including a bottom frame, a plurality of reinforcing blocks arranged in a matrix within the bottom frame, a plurality of reinforcing rib connecting rings arranged between the reinforcing blocks, and adjacent reinforcing rib connecting rings and reinforcing blocks, adjacent reinforcing blocks and reinforcing blocks, adjacent reinforcing rib connecting rings and reinforcing rib connecting rings, adjacent reinforcing rib connecting rings and the bottom frame, and adjacent reinforcing blocks and the bottom frame are all connected by reinforcing ribs arranged in a cross shape.

[0005] In the above technical solution, by setting a cross-shaped reinforcing rib structure at the bottom of the worktable, the load-bearing, bending, and deformation resistance of the worktable is enhanced. Furthermore, by connecting adjacent reinforcing rib connecting rings and reinforcing blocks, adjacent reinforcing blocks with each other, adjacent reinforcing rib connecting rings with each other, adjacent reinforcing rib connecting rings with the bottom frame, and adjacent reinforcing blocks with the bottom frame with reinforcing ribs in a cross-shaped distribution, the design can cope with different load changes on the worktable surface, so that the stress on the worktable surface is evenly distributed, thereby improving the overall rigidity of the worktable and meeting the rigidity requirements of multiple spindles of a multi-spindle heavy cutting machine when performing heavy cutting operations simultaneously.

[0006] Preferably, the top surface of the workbench is provided with multiple parallel and spaced T-shaped grooves to facilitate docking of the workbench with the fixture.

[0007] Preferably, the bottom frame of the star-shaped reinforcing rib plate is welded to the bottom surface of the workbench. Each reinforcing block is provided with multiple lower alignment fixing screw holes, and the top surface of the workbench is provided with upper alignment fixing screw holes corresponding to the lower alignment fixing screw holes. After the upper alignment fixing screw holes are aligned with the lower alignment fixing screw holes, they are fastened with screws. The above structural design can improve the connection strength between the star-shaped reinforcing rib plate and the workbench.

[0008] Preferably, the cross-shaped reinforcing rib plate is also equipped with a limiting installation block to facilitate the quick limiting installation of the workbench.

[0009] Preferably, each reinforcing block has a central hole to eliminate casting and mechanical stress.

[0010] The beneficial effects of the worktable structure of the CNC multi-spindle heavy cutting machine provided by this utility model are as follows: The worktable structure of this CNC multi-spindle heavy cutting machine is reasonably designed. By setting a star-shaped reinforcing rib plate structure at the bottom of the worktable, the load-bearing, bending, and deformation resistance of the worktable is enhanced. By designing the structure of the reinforced support bottom, the design of connecting the adjacent reinforcing rib connecting rings and reinforcing blocks, the adjacent reinforcing blocks, the adjacent reinforcing rib connecting rings, the adjacent reinforcing rib connecting rings and the bottom frame, and the adjacent reinforcing blocks and the bottom frame are all connected by reinforcing ribs distributed in a star shape. This design can cope with different load changes on the worktable surface, so that the stress on the worktable surface is evenly distributed, thereby improving the overall rigidity of the worktable and thus meeting the rigidity requirements when multiple spindles of the multi-spindle heavy cutting machine are performing heavy cutting at the same time.
