[0003] In reality, aluminum alloys are widely used in aviation, aerospace, automobiles, machinery manufacturing and other fields. Aluminum alloy thin-walled boxes give full play to the advantages of low density and light weight. In the field of electronic countermeasure technology, the boxes are often required to be light in weight and high in strength, but they are often difficult to process. Due to the thin wall, aluminum alloy materials are easy to deform. When traditional vises are clamped and processed, aluminum alloy thin-walled boxes are often not competent for such special shapes. The clamps are difficult to reach the position and cannot be fixed. In the process of clamping objects, the clamping force distribution of the vise is uneven, which is easy to deform or damage the objects, seriously affecting work efficiency and workpiece quality, resulting in excessively high costs.

[0004] In view of the above situation, the present application provides a special tooling for an aluminum alloy thin-walled box body to solve the above problem. Utility Model Content

[0005] In order to solve the problems in the prior art that, when traditional vises are used to clamp and process aluminum alloy thin-walled boxes, they are often unable to clamp objects of such special shapes and thus cannot be fixed, and that the clamping force is unevenly distributed during the process of clamping the objects, which easily causes deformation or damage to the objects, the present application provides a special tooling for aluminum alloy thin-walled boxes.

[0006] In order to achieve the above purpose, the technical solution adopted in this application is:

[0008] As a further improvement of the present invention, the locking hole is located at the central end surface of the tooling body, and the locking hole is opened in a rectangular shape and is opened at the four corners of the rectangle.

[0009] As a further improvement of the present invention, a support assembly is further provided on the tooling body, and the support assembly is provided along the center line of the long side of the tooling body.

[0032] Example:

[0033] A special tooling for an aluminum alloy thin-walled box body comprises a numerical control device, a tooling body 1 and a thin-walled box body 9, wherein the thin-walled box body 9 is arranged at the upper end of the tooling body 1, and the thin-walled box body 9 is arranged at the upper end of the thin-walled box body 9. The tooling body 1 is installed on the numerical control device through a plurality of locking holes 2 opened inside. A pair of first positioning components 4 and a pair of second positioning components 5 are arranged on the top surfaces of the long sides of both sides of the tooling body 1, and the first positioning components 4 and the second positioning components 5 are symmetrically arranged along the center line of the long side of the tooling body 1. The top surface of the tooling body 1 is also respectively provided with a plurality of first threaded holes 6, second threaded holes 7 and third threaded holes 8 for fixing the thin-walled box body 9.

[0034] To explain, we designed this tooling specifically for the problems of traditional vises in handling aluminum alloy thin-walled box bodies 9. It ensures the stable placement of the thin-walled box body 9 through the first positioning component 4 and the second positioning component 5. Furthermore, the thin-walled box body 9 is firmly fixed to the tooling by using the carefully designed first threaded hole 6, the second threaded hole 7 and the third threaded hole 8, in conjunction with bolts. Moreover, the apertures of these threaded holes are different, in order to distribute the clamping force more evenly and avoid deformation or damage of the product caused by uneven clamping force, thereby significantly improving the processing yield of the thin-walled box body 9. In addition, this tooling also uses high-strength materials to ensure that the accuracy of its positioning and clamping will not be reduced during long-term use. At the same time, we also took into account the ease of operation, so that this tooling can greatly improve work efficiency during use.

[0035] In general, this tooling provides an efficient, stable and reliable solution for the processing of aluminum alloy thin-walled box body 9 through precise positioning and clamping, as well as a unique clamping force distribution design. It has a significant effect on improving production efficiency and product quality. We believe that this tooling will play an important role in the processing of aluminum alloy thin-walled box body 9.

[0036] Specifically, the locking hole 2 is located at the central end face of the tooling body 1, and the locking hole 2 is opened in a rectangular shape and is opened at the four corners of the rectangle. Such an opening layout can ensure the tight connection between the tooling body 1 and the CNC equipment to the greatest extent, thereby making subsequent work more stable.

[0037] Combined with the accompanying drawings Figure 1-Figure 7A support assembly 3 is also provided on the tooling body 1, and the support assembly 3 is arranged along the center line of the long side of the tooling body 1, and the support assembly 3 includes a first support block 31 and a second support block 32, and at least two of the first support blocks 31 and the second support blocks 32 are respectively provided, wherein a single first support block 31 and a single second support block 32 are combined into a support table, and at least two groups of the support tables are arranged in a linear array along the center line of the long side of the tooling body 1.

[0038] It is explained that the support assembly 3 configured at the center of the tooling body 1 can fully fit the wall surface of the thin-walled box body 9 during the fixing of the thin-walled box body 9 and the processing, provide a stable support for the thin-walled box body 9, improve the thin-wall strength, and thus improve the processing efficiency and shorten the processing cycle. At the same time, the design of the support assembly 3 can also effectively reduce the breakage rate of the thin-walled box body 9, improve product quality, and further enhance the competitiveness of the enterprise. In future work, we also need to continue to optimize the structural design of the support assembly 3 to meet the processing needs of more different types of thin-walled box bodies 9 and achieve more efficient and more precise processing effects.

[0039] It is worth mentioning that the first positioning component 4 includes a first protrusion 41 and a first long strip 42, and the first protrusion 41 and the first long strip 42 are arranged at a right angle. The second positioning component 5 includes a second protrusion 51 and a second long strip 52, and the second protrusion 51 and the second long strip 52 are arranged at a right angle. A semicircular alignment groove is also provided at the right angle formed by the second protrusion 51 and the second long strip 52. The apertures of the first threaded hole 6, the second threaded hole 7 and the third threaded hole 8 are all different, and through holes are provided on the thin-walled box body 9 corresponding to the first threaded hole 6, the second threaded hole 7 and the third threaded hole 8.
