Description

Technical Field

[0001] This utility model relates to the technical field of conical truss milling structure, and in particular to a front splicing structure for conical truss milling based on a five-axis machining center. Background Technology

[0002] In the milling process of frustum conical components on a five-axis machining center, the design of the blank splicing structure directly affects the final product's forming quality and processing efficiency. Traditional processes typically employ circumferential splicing, where multiple thick wooden boards are tightly wrapped around a central wooden stake along the circumference to form a cylindrical blank matrix. While this method achieves basic structural fixation, it reveals significant drawbacks in actual processing: First, the wood fiber direction is difficult to match with the milling trajectory, resulting in broken and misaligned grain patterns on the surface of the frustum after milling, affecting aesthetic consistency. Second, due to the combined effect of the splicing gaps between the boards and the anisotropic properties of the wood, stress concentration easily occurs at the joints during milling, leading to cracks or even structural failure, reducing the finished product's yield. Third, the splicing of thick wooden boards requires a large processing allowance, and both the central wooden stake and the outer boards need to be processed from whole pieces of wood, resulting in low raw material utilization, contradicting the concept of green manufacturing. These problems have long constrained the processing efficiency and economy of high-precision wooden frustum conical components, necessitating technological breakthroughs through structural innovation and process optimization.

[0003] It is evident that existing technologies still need improvement and enhancement. Utility Model Content

[0004] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a pre-splitting structure for milling a truncated cone based on a five-axis machining center, which aims to solve the technical problems of poor appearance consistency, easy cracking and high material consumption caused by the traditional circumferential splicing structure in the prior art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A front splicing structure for a cone-shaped milling machine based on a five-axis machining center includes a first wooden board, a second wooden board, a third wooden board, a fourth wooden board, and a fifth wooden board of the same thickness, which are fixedly stacked from bottom to top. The size of each layer of wooden boards decreases from the bottom layer to the top layer, and the central axes of each layer of wooden boards coincide.

[0007] The aforementioned cone-shaped milling front splicing structure based on a five-axis machining center includes raised positioning blocks on the sides of the first wooden board near the second wooden board, the second wooden board near the third wooden board, the third wooden board near the fourth wooden board, and the fourth wooden board near the fifth wooden board; and recessed positioning holes on the sides of the second wooden board near the first wooden board, the third wooden board near the second wooden board, the fourth wooden board near the third wooden board, and the fifth wooden board near the fourth wooden board, with the upper positioning holes used to accommodate the positioning blocks of the adjacent lower layers.

[0008] The aforementioned cone-shaped milling front splicing structure based on a five-axis machining center, wherein the positioning blocks and positioning holes of each layer of wooden boards are located on the central axis of that layer of wooden boards.

[0009] The aforementioned cone-shaped milling front splicing structure based on a five-axis machining center has a structure in which each layer of wooden boards is a square wooden board, and the side length ratio of the fifth, fourth, third, second and first wooden boards is 1:2:3:4:4.6.

[0010] The aforementioned cone-shaped milling front splicing structure based on a five-axis machining center has a series of circular wooden boards in each layer, with the diameter ratio of the fifth, fourth, third, second, and first wooden boards being 1:2:3:4:4.6.

[0013] Beneficial effects:

[0014] This invention provides a pre-assembly structure for milling a frustum of a cone using a five-axis machining center. The structure comprises five wooden boards of equal thickness, fixedly stacked from bottom to top. The size of each board layer decreases progressively from the bottom to the top, and the central axes of each layer coincide. A frustum of a cone is obtained by milling this structure using a five-axis machining center. The first board forms the table of the frustum, and the fifth board forms the apex. Because the table of the frustum is a single piece of wood, the wood fiber texture is natural and smooth, and cracks are less likely to occur. This pre-assembly structure for milling a frustum of a cone using a five-axis machining center replaces circumferential splicing with stacked and spliced ​​layers of boards, resulting in a consistent appearance of the frustum table and reducing the likelihood of cracks. By progressively decreasing the size of each board layer from bottom to top, with the largest first board serving as the table of the frustum and the smallest fifth board as the apex, wood waste can be minimized.

[0024] This utility model provides a front splicing structure for milling cone trusses based on a five-axis machining center. To make the purpose, technical solution, and effects of this utility model clearer and more explicit, the following describes this utility model in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0025] In the description of this utility model, it should be understood that the terms "upper," "lower," "left," and "right," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or a specific orientational structure and operation. Therefore, they should not be construed as limitations on this utility model. Furthermore, "first" and "second" are only for descriptive purposes and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "multiple" means two or more.

[0026] Please see Figures 1 to 2 , Figure 5 As shown, this utility model provides a pre-assembly structure for milling a frustum of a cone based on a five-axis machining center. It includes a first wooden board 1, a second wooden board 2, a third wooden board 3, a fourth wooden board 4, and a fifth wooden board 5, all of the same thickness and fixedly stacked from bottom to top. The size of each layer of wooden boards decreases progressively from the bottom to the top, and the central axes of each layer coincide. In this embodiment, the milled frustum of a cone is used to install it onto a specially designed bracket to assemble it into a coffee table. The frustum of a cone is milled using a five-axis machining center. The first wooden board 1 forms the tabletop of the frustum, and the fifth wooden board 5 is machined to form the apex of the cone. Because the tabletop of the frustum of a cone is a single piece of wood, its wood fiber texture is natural and smooth, and it is less prone to cracking. This pre-splicing structure for milling a truncated cone based on a five-axis machining center replaces circumferential splicing by stacking and splicing layers of wooden boards. The resulting truncated cone has a consistent appearance and is less prone to cracking. By gradually reducing the size of each layer of wooden boards from bottom to top, so that the largest first wooden board 1 serves as the truncated cone and the smallest fifth wooden board 5 serves as the apex of the truncated cone, wood loss can be minimized.

[0027] Please see Figures 1 to 2As shown, each of the following planks has a raised positioning block 6: the side of the first plank 1 closest to the second plank 2, the side of the second plank 2 closest to the third plank 3, the side of the third plank 3 closest to the fourth plank 4, and the side of the fourth plank 4 closest to the fifth plank 5. Each of the following planks also has a recessed positioning hole 7: the side of the second plank 2 closest to the first plank 1, the side of the third plank 3 closest to the second plank 2, the side of the fourth plank 4 closest to the third plank 3, and the side of the fifth plank 5 closest to the fourth plank 4. The upper positioning hole 7 is used to accommodate the positioning block 6 of its adjacent lower layer. In this embodiment, the positioning block 6 and positioning hole 7 of each plank layer are located on the central axis of that layer. Connecting each plank layer to the positioning block 6 via the positioning hole 7 allows for quick positioning to the central axis position during splicing, improving splicing efficiency and accuracy, thereby increasing processing efficiency and reducing material consumption caused by errors.

[0028] Please see Figure 3 As shown, in this embodiment, each layer of wood planks is a square plank, and the diameter of the frustum is equal to the side length of the square. This results in less waste material being removed during milling, reducing material consumption. The side length ratio of the fifth plank 5, fourth plank 4, third plank 3, second plank 2, and first plank 1 is 1:2:3:4:4.6, ensuring a smooth conical surface after milling each layer. The finished frustum has its edge near the platform formed as a circumferential surface perpendicular to the platform. Therefore, setting the ratio of the first plank 1 to the second plank 2 at 4.6:4 further reduces material consumption.

[0029] In some other embodiments, each layer of wood is a circular wood, and the diameter of the frustum is equal to the diameter of the circle. This results in less waste material being removed during milling, reducing the amount of wood material consumed. The diameter ratio of the fifth wood, fourth wood, third wood, second wood, and first wood is 1:2:3:4:4.6, ensuring a smooth conical surface after milling each layer of wood. The finished frustum has its edge near the tabletop set as a circumferential surface perpendicular to the tabletop. Therefore, setting the ratio of the first wood to the second wood to the second wood to the second wood to the second wood to the first ... fourth wood to the second wood to the fourth wood to the first wood to the second wood to the fourth wood to the first wood to the second wood to the fourth wood to the fourth wood to the fifth wood to the first wood to the fourth wood to the fourth wood to the fifth wood to the fourth wood to the fifth wood to the fourth wood to the fifth wood to the fourth wood to the fifth wood to the fourth wood to the fifth wood to the fourth wood to the fifth wood to the fourth wood to the fifth wood to the fourth wood to the fifth wood to the fourth wood to the fifth wood to the fourth wood to the fifth wood to the fourth wood to the fifth wood to the fourth wood to the fifth wood to the fourth wood to the fifth wood to the fourth wood to the fifth wood to the fourth wood to the fifth wood to the fourth wood to the fifth wood to the fourth wood to the fifth wood to the fourth wood to the fifth wood

[0030] Furthermore, the ratio of the thickness of a single layer of wood to the side length or diameter of the fifth wood panel 5 is 1:2 to 1:4. The apex angle of the frustum processed within this ratio range is 90° to 126°. From the perspective of material consumption, this ratio range consumes less material; from the perspective of appearance, the coffee table made from the frustum obtained within this ratio range is more aesthetically pleasing.

[0031] Please see Figure 4 As shown, in this embodiment, the ratio of the thickness of a single layer of wood to the side length or diameter of the fifth wood 5 is 1:2.6, and the apex angle of the resulting frustum is 104°. This ratio is more in line with the production requirements of coffee tables.

[0032] In summary, this utility model replaces circumferential splicing with overlapping and splicing of each layer of wooden boards, resulting in a truncated cone with a consistent appearance and less susceptibility to cracking. By progressively decreasing the size of each layer of wooden boards from bottom to top, so that the largest first wooden board 1 serves as the truncated cone and the smallest fifth wooden board 5 serves as the apex of the truncated cone, wood waste can be minimized.

[0033] It is understood that those skilled in the art can make equivalent substitutions or changes based on the technical solution and inventive concept of this utility model, and all such substitutions or changes should fall within the protection scope of the appended claims of this utility model.
