Description

Technical Field

[0001] This invention relates to the field of aerospace component manufacturing, specifically to a processing device for curved wall panels and its usage method. Background Technology

[0002] In the field of aerospace component manufacturing, curved panels are key components forming the shape of aircraft fuselages and wings, and are among the most common part types. Especially for larger, thin-walled curved panels, which are formed by sheet metal roll bending or gate bending, these parts generally suffer from problems such as inconvenient clamping and easy deformation during processing due to factors like thin wall thickness, springback deformation, and large dimensions. Currently, clamping with a pressure plate is commonly used, which is time-consuming and labor-intensive, resulting in long part alignment times, low efficiency, and clamping deformation, severely impacting processing quality and efficiency.

[0003] The curved wall panel has multiple light-reducing grooves, which are traditionally processed using acid corrosion. This method suffers from uneven wall thickness, poor surface quality, environmental pollution, low efficiency, and long processing cycles. For the structural characteristics of thin-walled curved wall panels, specialized clamping fixtures and CNC equipment can achieve rapid processing with significantly improved efficiency and consistent wall thickness. This invention relates to a processing device and method for curved wall panels. Summary of the Invention

[0004] To address the aforementioned problems, this invention proposes a processing device for arc-shaped wall panels and a method for using them.

[0005] A processing device for an arc-shaped wall panel includes a base placed on a machine tool worktable, an arc-shaped wall panel disposed on the base, an upper cover plate disposed on the arc-shaped wall panel to ensure a gap between the cover plate and the base, and a pressure plate disposed on the arc-shaped wall panel to leave a machining position.

[0006] As a further improvement of the present invention, the base includes a surface one that fits against the arc-shaped wall panel, a plane that fits against the machine tool worktable, a surface two that mates with the upper cover plate, a surface three, and a hole two.

[0007] As a further improvement of the present invention, the arc-shaped wall panel includes a surface five that is in contact with a surface one, a surface four that cooperates with a pressure plate one, and a light-reducing groove provided in the arc-shaped wall panel itself.

[0008] As a further improvement of the present invention, the upper cover plate includes a surface six that fits with surface four, a surface seven that mates with surfaces two and three, a surface eight, a hole three that mates with pressure plate one, a hole five that mates with the base, a surface eleven, and a hole seven.

[0009] As a further improvement of the present invention, the second and third surfaces and the seventh and eighth surfaces have a gap of 0.5 mm.

[0010] As a further improvement of the present invention, the pressure plate includes an upper surface that mates with surface four, a hole six that mates with hole three, and surfaces nine and ten that mate with the upper cover plate.

Fitting the pressure plate one: Fit the upper surface of the pressure plate one to the surface four of the arc-shaped wall panel, adjust the position of the surface ten on the pressure plate one and the hole three on the upper cover plate, and leave space for the machining of the light-reducing groove on the arc-shaped wall panel. Tighten with standard bolts.

[0018] S6. Adjust the machine tool position: Adjust the coordinate position of the CNC machine tool, machine the surface of the light reduction groove feature, and adjust the position of the pressure plate one according to the position of the machined light reduction groove surface. The installation method is the same as step S5.

[0019] S7. Remove the base: After all the light-reducing grooves on the curved wall panel are processed, remove the standard bolts connecting the base and the top cover.

[0041] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below.

[0042] like Figures 1 to 14 As shown, a processing device for an arc-shaped wall panel includes a base 1 placed on a machine tool worktable, an arc-shaped wall panel 4 disposed on the base 1, an upper cover plate 2 disposed on the arc-shaped wall panel 4 to ensure a gap between it and the base 1, and a pressure plate 3 disposed on the arc-shaped wall panel 4 to leave a machining position.

[0043] This invention solves the technical problems of curved surface clamping and machining deformation. At the same time, it adopts CNC machining to solve many problems such as uneven wall thickness and poor surface quality, which are polluting to the environment, inefficient and have long processing cycles. By using a clamping fixture with an arc-shaped wall plate, it effectively avoids problems such as clamping deformation, time consumption, difficulty in alignment, uneven wall thickness and poor surface quality. It has the advantages of quick clamping, easy operation, good wall thickness consistency, and significantly improved processing quality and efficiency.

[0044] like Figure 5 and Figure 6 As shown, the base 1 of the present invention includes a surface 101 that fits against the arc-shaped wall panel 4, a plane 102 that fits against the machine tool worktable, a surface 103 that mates with the upper cover plate 2, a surface 104, and a hole 106.

[0045] like Figure 11 and Figure 12As shown, specifically, the arc-shaped wall panel 4 includes a surface 402 that fits against surface 101, a surface 401 that cooperates with pressure plate 3, and a light-reducing groove 403 provided on the arc-shaped wall panel 4 itself.

[0046] The curved wall panel 4 has multiple light-reducing grooves 403, which are traditionally processed by acid corrosion. This process results in uneven wall thickness, poor surface quality, environmental pollution, low efficiency, and long processing cycle. In response to these technical problems, this invention designs a clamping fixture for the curved wall panel, which effectively avoids clamping deformation, time consumption, difficulty in alignment, and uneven wall thickness.

[0047] like Figure 2 , Figure 13 and Figure 14 As shown, the machining fixture also includes a pressure plate 2 5 used in machining the contour of the curved wall panel. The pressure plate 2 5 includes surface 13 502, surface 14 503 and surface 12 501 that mates with surface 5 402.

[0048] like Figure 7 and Figure 8 As shown, the upper cover plate 2 of the present invention is further structurally refined. The upper cover plate 2 includes a surface 6 201 that is attached to surface 401, a surface 7 202 that mates with surface 2 103 and surface 3 104, a surface 8 203, a hole 3 204 that mates with pressure plate 1 3, a hole 5 205 that mates with base 1, a surface 11 206, and a hole 7 207.

[0049] Furthermore, the second surface 103, the third surface 104, the seventh surface 202, and the eighth surface 203 have a gap of 0.5 mm.

[0050] like Figure 9 and Figure 10 As shown, the pressure plate 3 includes an upper surface 301 that mates with surface 401, a hole 304 that mates with hole 204, a surface 9 303 that mates with the upper cover plate 2, and a surface 10 302.

[0057] S6. Adjust the machine tool position: Adjust the coordinate position of the CNC machine tool, machine the surface of the light-reducing groove 403 feature, and adjust the position of the pressure plate 3 according to the position of the machined light-reducing groove 403 surface. The installation method is the same as step S5.

[0058] S7. Remove base 1: After all the light-reducing grooves 403 on the arc-shaped wall panel 4 are processed, remove the standard bolts connecting base 1 and upper cover 2.
