Description

Technical Field

[0001] The utility model belongs to the technical field of aircraft assembly hole making, and in particular relates to a device for making rivet holes for floating support plate nuts. Background Art

[0002] With the rapid development of my country's aerospace technology, the demand for improving aircraft manufacturing efficiency has also increased accordingly. As one of the connecting parts on the aircraft, the floating support plate nut is used in large quantities in the aircraft manufacturing process. When manufacturing the floating support plate nut, it is necessary to punch rivet holes on the support plate for subsequent installation. In the actual manufacturing process, due to design requirements, the floating support plate nut has different shapes, and the rivet holes may be made in narrow areas when making holes, and it is necessary to avoid R areas, sunken areas or areas with reinforcing ribs. The existing hole making method is to use a fixed mold to fix the floating support plate nut, and then manually perform the hole punching operation. Due to the shape of the floating support plate nut, it is easy to cause insufficient hole margins or easily make holes in R areas, sunken areas and areas with reinforcing ribs, causing parts to be out of tolerance or scrapped, resulting in property losses and affecting the project cycle. Utility Model Content

[0003] In order to solve the above problems, the utility model provides a device for preparing rivet holes for floating support plate nuts, which fixes the floating support plate nuts through a bottom plate and a top plate, and then performs the hole making work.

[0004] A device for preparing rivet holes for floating support plate nuts comprises a base plate and a top plate. A positioning post is disposed in the middle of the base plate, perpendicular to the base plate. A positioning hole is disposed in the middle of the top plate, the diameter of the positioning hole matching that of the post. The post can pass through the hole, allowing the top plate to be positioned over the post, thereby allowing the base and top plates to clamp the floating support plate nut in place. To maintain the relative angle between the base and top plates, vertical positioning slots are provided on the sides of the post, and positioning holes are provided on the sides of the holes. The shape of the positioning holes matches the slots. When the top plate is positioned over the post, positioning blocks can be engaged within the slots, thereby fixing the angle of the top plate. To facilitate hole-making, guide holes are provided in the base and top plates, respectively, so that the guide holes on the base and top plates overlap vertically. Drilling equipment can be used to drill holes through the guide holes into the floating support plate nut.

[0005] In order to perform multiple drilling operations at one time, two guide holes are provided on the bottom plate and the top plate respectively.

[0006] In order to facilitate the operation of the base plate, a handle is provided on the side of the base plate, and the handle extends outward along the horizontal plane of the base plate. During the hole making process, the handle can be held by hand to fix the position of the base plate.

[0007] In order to increase the operability of the handle, the end of the handle is set to be bent downward, which is more suitable for the shape of the hand and increases the gripping and fixing effect.

[0008] The device for preparing rivet holes for floating support plate nuts provided by the utility model can completely fix the floating support plate nuts and maintain the accuracy of the drilling position. The device is simple and fast to operate, has a simple structure and is easy to manufacture, can greatly reduce the difficulty of the hole making work, and improve the product yield.

[0013] To further illustrate the concept of the present invention, the following will further describe the specific implementation of the present invention with reference to the accompanying drawings: Example 1

[0014] A device for preparing rivet holes for floating support plate nuts consists of a bottom plate 1 and a top plate 2. Two metal plates of the same shape are used as the bottom plate 1 and the top plate 2. A positioning column 3 is vertically welded in the middle of the bottom plate 1, and a vertical positioning groove 6 is cut on the side of the positioning column 3. A hole is drilled in the middle of the top plate 2, and the position and shape of the hole are consistent with the positioning column 3 to form a positioning hole 4, such as Figure 2 As shown, when cutting, it is necessary to reserve positioning blocks 5 around the positioning holes 4 so that the positioning blocks 5 can fit neatly into the positioning grooves 6. Then, the top plate 2 is placed on the positioning posts 3 through the positioning holes 4, so that the top plate 2 and the bottom plate 1 fit together. Then, according to the predetermined floating support nut hole positions, guide holes 7 are drilled on the top plate 2 and the bottom plate. When drilling the guide holes 7, start from the top of the top plate 2 and drill downward toward the bottom plate 1. After the top plate 2 and the bottom plate 1 are drilled through, guide holes 7 are formed. Two sets of guide holes 7 are drilled in the above manner. Example 2

[0015] A device for preparing rivet holes for floating support plate nuts consists of a base plate 1 and a top plate 2. Two identically shaped metal plates are used as base plate 1 and top plate 2. A positioning post 3 is vertically welded to the center of base plate 1, and a vertical positioning groove 6 is cut into the side of the positioning post 3. A metal handle 8 is then welded to the side of base plate 1, and the end of handle 8 is bent downward. A hole is drilled in the center of top plate 2, the position and shape of the hole matching the positioning post 3, to form a positioning hole 4. During cutting, it is important to reserve positioning blocks 5 around the perimeter of positioning hole 4 so that they fit neatly into positioning groove 6. Then put the top plate 2 on the positioning column 3 through the positioning hole 4, so that the top plate 2 and the bottom plate 1 are fitted together, and then according to the predetermined floating support plate nut hole position, hold the handle 8 to fix the bottom plate 1, and drill guide holes 7 on the top plate 2 and the bottom. When drilling the guide holes 7, start from the top of the top plate 2 and drill downward in the direction of the bottom plate 1. After the top plate 2 and the bottom plate 1 are drilled through, the guide holes 7 are formed. Drill two sets of guide holes 7 in the above manner, as shown in FIG. Figure 1 shown.

[0016] Taking Example 2 as an example, when drilling the floating support plate nut, the floating support plate nut is placed on the positioning column 3, and then the top plate 2 is placed on the positioning column 3, so that the top plate 2 and the bottom plate 1 sandwich the floating support plate nut. Because the positioning hole 4 has a positioning block 5, the angle between the top plate 2 and the bottom plate 1 is fixed, so that the guide hole 7 on the top plate 2 and the bottom can correspond. After securing the floating support plate nut, the bottom plate 1 is fixed by holding the handle 8 by hand, and then the drilling operation is carried out. Drill downward from the guide hole 7 on the top plate 2, and let the drill bit drill out from the guide hole 7 on the bottom plate 1, thus completing the drilling of one rivet hole. Then, drill from the other guide hole 7 to complete the entire drilling operation.

[0017] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, various changes and variations are possible. Any modifications, equivalent replacements, improvements, etc. made using the present invention should be included in the scope of protection of the present invention.
