Description

TECHNICAL FIELD

[0001] The present specification belongs to the technical field of riveting, and particularly relates to a riveting nut and a riveting method for a plate. BACKGROUND

[0002] In the prior art, the fixing and connection of a plate are generally achieved through riveting of a nut. When riveting is performed through a nut, a worker can only fix and connect a single plate. When the worker needs to simultaneously rivet multiple plates, the multiple plates will rotate relative to each other. After being subjected to vibration, the multiple plates will fall off from the outer wall of the nut.

[0003] In another case, the existing nut can only connect an external part through one end. That is, the existing nut cannot meet the multiple installation processes of the plate and the external part.

[0004] At present, no effective solution has been proposed for the above problems.

[0005] It should be noted that the above introduction to the technical background is only for the convenience of clearly and completely describing the technical scheme of the present application and for the convenience of understanding by those skilled in the art. The above technical scheme cannot be considered as known to those skilled in the art merely because it is described in the background section of the present application. SUMMARY

[0006] The present specification aims to provide a riveting nut and a riveting method for a plate to solve the above problems.

[0007] The present specification provides a riveting nut, which comprises:

[0010] a third connecting portion is arranged in the middle of the outer wall of the main body portion, and the third connecting portion is used to connect multiple plates;

[0011] The third connecting portion has two states before and after riveting,

[0012] Before riveting, the middle position of the third connecting portion is arranged in the inner wall of at least two plates;

[0013] After riveting, the positions near the two ends of the third connecting portion are extruded to form deformation portions, and the two deformation portions are in contact with the adjacent plates on the side of the plates to fix all the plates arranged in layers.

[0014] Preferably, the outer wall of the third connecting part is provided with multiple spiral lines or multiple vertical lines at intervals, and the multiple spiral lines or multiple vertical lines form a receiving groove to accommodate the plate material.

[0016] Preferably, the first connecting portion and the second connecting portion have the same thickness, and the ratio of the thickness of the third connecting portion to the thickness of the first connecting portion or the second connecting portion is 1:2.

[0017] Preferably, the fit between the plurality of plates and the third connecting portion is a clearance fit.

[0018] Preferably, the outer diameter of the third connecting part is set to 7mm, 9mm, 11mm or 13mm, and the dimensional deviation of the outer diameter of the third connecting part is 0.15mm.

[0019] A method for riveting sheet metal, comprising:

[0020] Multiple boards are stacked together;

[0021] Multiple stacked plates are threaded through a third connecting portion on the nut, wherein the third connecting portion is disposed on the outer wall of the nut and includes multiple threads or multiple vertical lines spaced apart.

[0022] The upper and lower dies simultaneously press the nuts through which multiple plates are inserted, causing a deformation portion to form on the third connecting part near the plate. This deformation portion then presses against the plate on one side, and a groove is formed between the multiple threads or vertical lines to accommodate material at the point where the plate and the deformation portion press. The third connecting part abuts against the inner walls of the multiple plates, and the groove accommodates material from the inner walls of the plates.

[0023] The third connecting portion abuts against the inner walls of the plurality of plates, and the receiving groove is used to accommodate the inner wall material of the plates.

[0024] Preferably, when the third connecting part is provided on the outer wall of the nut, a mounting hole is provided at the middle position of the end of the main body of the nut. The mounting hole is a through hole, and a first connecting part and a second connecting part are respectively provided near both ends of the inner wall of the mounting hole.

[0025] Preferably, the thickness of the first connecting part is the same as the thickness of the second connecting part, and when the third connecting part is provided, the ratio of the thickness of the third connecting part to the thickness of the first connecting part or the thickness of the second connecting part is set to 1:2.

[0026] Compared with the prior art, the beneficial effects of the present invention are:

[0027] 1. The present invention provides a first connecting part, a second connecting part and a third connecting part at the middle position and both ends of the main body of the nut. The third connecting part can fix multiple plates together, and can also connect to external parts through the first connecting part and the second connecting part.

[0028] 2. The present invention provides deformation parts near both ends of the third connection part, which can compress multiple plates, making the connection of the plates more stable.

[0029] 3. The present invention provides multiple spiral lines or multiple vertical lines at intervals in the third connecting part, and forms a receiving groove between the multiple spiral lines or multiple vertical lines. The receiving groove can accommodate the material of the board, thereby generating a force to prevent the board from rotating.

[0030] 4. The present invention sets a preset distance between the first connecting part and the second connecting part so that the first connecting part and the second connecting part will not interfere with the formation of the deformable part.

[0031] 5. By setting the thickness of the first connecting part and the second connecting part to be the same, and setting the ratio of the thickness of the third connecting part to the thickness of the first connecting part or the thickness of the second connecting part to 1:2, the present invention can make the deformable part more stable during formation.

[0041] Reference Figure 1 As shown, this application provides a riveting nut, comprising:

[0042] The main body 11 has a mounting hole 12 at the middle position of its end;

[0043] A first connecting part 121 and a second connecting part 122 are respectively provided near both ends of the mounting hole 12;

[0044] A third connecting part 111 is provided at the middle position of the outer wall of the main body 11. The third connecting part 111 is used to connect multiple plates 2.

[0045] The third connecting part 111 has two states: before riveting and after riveting.

[0046] Before riveting, the middle position of the third connecting part 111 is inserted into the inner wall of at least two plates 2;

[0047] After riveting, the third connecting part 111 is extruded to form a deformable part 112 near both ends. The two deformable parts 112 on the side facing the plate 2 abut against the adjacent plate 2 to fix all the stacked plates 2.

[0048] according to Figure 1 , Figure 2 , Figure 3 and Figure 4 The nut 1 is connected to the plate 2. In this embodiment, the nut 1 has a main body 11, on which a mounting hole 12 and a third connecting part 111 are provided. Specifically, the mounting hole 12 is opened on the end side of the main body 11, and the mounting hole 12 can be configured as a through hole. When the mounting hole 12 is configured as a through hole, a first connecting part 121 and a second connecting part 122 are respectively provided near both ends of the inner wall of the mounting hole 12.

[0049] With the above structure, the third connecting part 111 is used to connect the plate 2. In this embodiment, by providing the third connecting part 111, it is possible to rivet with multiple plates 2 together. Furthermore, by providing the first connecting part 121 and the second connecting part 122 in the mounting hole 12, the plate 2 can be fixedly connected to two external parts after riveting. In normal operation by those skilled in the art, both the first connecting part 121 and the second connecting part 122 can be provided with threads, so that they can be threadedly connected to external parts.

[0050] In this embodiment, the third connecting part 111 is configured with two states: before riveting and after riveting. Before riveting, according to... Figure 2 , Figure 3 and Figure 5 Multiple plates 2 are inserted through the third connecting part 111, and the third connecting part 111 is cylindrical. Then, according to... Figure 1 and Figure 4 After riveting, the two sides of the third connecting part 111 near the plate 2 are compressed and deformed, thus forming the deformed part 112. Figure 1 In the middle, the two deformed parts 112 on the side facing the plate 2 both abut against the adjacent plate 2.

[0051] It is worth noting that in both of the aforementioned states, before riveting, multiple plates 2 are inserted through the outer wall of the third connecting portion 111, and the inner walls of the multiple plates 2 are in contact with the outer wall of the third connecting portion 111. After riveting, the deformed portion 112 forms an abutment against the outer walls of adjacent plates 2. The aforementioned structure presses the multiple plates 2 together on their inner walls while simultaneously applying a force to bring them closer together on their outer walls. This prevents rotation and slippage of the multiple plates 2 during connection.

[0052] Preferably, the outer wall of the third connecting portion 111 is provided with multiple spiral lines or multiple vertical lines at intervals, and a receiving groove is formed between the multiple spiral lines or multiple vertical lines to accommodate the sheet material. In the above embodiment, the middle position of the third connecting portion 111 abuts against the inner wall of the holes of multiple sheet materials 2, and the deformable portion 112 abuts against the sheet material 2 on the side facing the sheet material 2. In this embodiment, by providing multiple spiral lines or multiple vertical lines at intervals, the receiving groove between the multiple spiral lines or multiple vertical lines can accommodate the material of the sheet material 2 throughout the riveting process.

[0053] Specifically, before riveting, when the sheet metal 2 is inserted onto the outer wall of the third connecting part 111, part of the material on the inner wall of the sheet metal 2 is squeezed into the groove. After riveting, the extruded deformed part 112 abuts against the sheet metal 2, and the abutting part can also accommodate the material of the side wall through the groove.

[0054] The material embedded in the aforementioned groove is pressed tightly against the inner wall of the groove. When the plate 2 tends to rotate, the material embedded in the plate 2 is pressed against the inner wall of the groove, generating a force that resists the rotation of the plate 2 during the pressing process. That is, a groove is formed between multiple spiral lines or multiple vertical lines, and the groove and the material embedded in the groove block each other, thereby preventing the plate 2 from rotating. When the plate 2 tends to fall off, the deformable part 112 presses against the plate 2, thereby preventing the plate 2 from falling off.

[0055] Preferably, a preset distance is provided between the ends of the first connecting portion 121 and the second connecting portion 122 that are intended to be close together. Figure 3 In this embodiment, the first connecting portion 121 and the second connecting portion 122 are disposed on the inner wall of the mounting hole. In another embodiment of this application, both the first connecting portion 121 and the second connecting portion 122 are provided with threads for threaded connection to external components. During riveting, the third connecting portion 111 is deformed by compression. If the length of the threads provided by the first connecting portion 121 and the second connecting portion 122 overlaps with the deformed portion of the third connecting portion 111, during the riveting process, the applied force may cause partial breakage of the threads provided on the first connecting portion 121 and the second connecting plate 122. Partial breakage of the connecting threads reduces the overall connection effect of the threads, leading to the overall failure of the nut 2 connection.

[0056] During the riveting process, deformation riveting is achieved by applying force to both ends of the nut 1. Preferably, the first connecting portion 121 and the second connecting portion 122 have the same thickness, and the ratio of the thickness of the third connecting portion 111 to the thickness of the first connecting portion 121 or the second connecting portion 122 is 1:2. During riveting, the thickness of the third connecting portion 111 is smaller, making it more prone to deformation under stress. That is, setting the thickness of the third connecting portion 111 to be thinner than the thickness of the first connecting portion 121 and the second connecting portion 122 allows the deformable portion 112 to form in a shorter time, thereby making the formed structure more stable.

[0057] This specification also provides a sheet metal riveting structure, including:

[0058] Board 2, multiple boards 2 stacked together;

[0059] Nut 1 is inserted through multiple plates 2. Nut 1 has a main body 11. A mounting hole 12 is provided at the middle position of the end of the main body 11. A first connecting part 121 and a second connecting part 122 are respectively provided near the two ends of the inner wall of the mounting hole 12.

[0060] A preset distance is provided between the ends of the first connecting part 121 and the second connecting part 122 that are close to each other;

[0061] A third connecting part 111 is provided at the middle position of the outer wall of the main body 11, and the third connecting part 111 is used to connect with the plate 2;

[0062] The deformed portions 112 are formed by extrusion near both ends of the outer wall of the third connecting portion 111, and the two deformed portions 112 abut against the side wall of the plate 2 on the side facing the plate 2.

[0063] The third connecting part 111 is configured with multiple spiral lines or multiple vertical lines, and a receiving groove is formed between the multiple spiral lines or multiple vertical lines to receive the material of the plate 2.

[0064] In this embodiment, the plate 2 and the nut 2 are riveted together. By passing multiple plates 2 through a third connecting part 111 on the nut 2 and providing a deformation part 112 that abuts against the plate 2, the plates 2 are fixedly connected.

[0065] Multiple spiral lines or vertical lines are spaced apart on the third connecting part 111, forming a receiving groove between them. The receiving groove can accommodate the material of the plate 2. The material embedded in the receiving groove is in contact with the inner wall of the receiving groove. When the plate 2 rotates, it can generate a blocking force on the material embedded in the receiving groove, thereby preventing the plate 2 from rotating.

[0066] A mounting hole 12 is provided at one end of the main body 11. A first connecting part 121 and a second connecting part 122 are respectively provided near both ends of the inner wall of the mounting hole 12. The first connecting part 121 and the second connecting part 122 are used for fixed connection to external parts.

[0067] The first connecting part 121 and the second connecting part 122 are provided with threads, so that the nut 2 can be threadedly connected to external parts. A preset distance is provided at the end of the first connecting part 121 and the second connecting part 122 that are close to each other, so as to avoid the threads affecting the formation of the deformation part 112 on the third connecting part 111.

[0068] In the plate riveting structure, multiple plates 2 are fitted onto the outer wall of the third connecting part 111. Preferably, the fit between the multiple plates 2 and the third connecting part 111 is a clearance fit. The clearance fit structure makes the process of fitting the multiple plates 2 more stable. That is, the aforementioned structure allows the plates 2 to be accurately fitted into the middle position of the third connecting part 111 during fitting.

[0069] More preferably, the outer diameter of the third connecting part 111 is set to 7mm, 9mm, 11mm or 13mm, and the dimensional deviation of the outer diameter of the third connecting part 111 is 0.15mm.

[0070] This embodiment also provides a method for riveting sheet metal, including:

[0071] Multiple boards are stacked in two layers;

[0072] Multiple stacked plates 2 are threaded through the third connecting part 11 on the nut 1. The third connecting part 11 is located on the outer wall of the nut 1 and includes multiple threads or multiple vertical lines spaced apart.

[0073] The upper and lower molds simultaneously press the nuts 1 through which multiple plates 2 are inserted, so that the third connecting part 11 is pressed near the plate 2 to form a deformed part 112. The deformed part 112 presses against the plate 2 on the side facing the plate 2, and a receiving groove is formed between the multiple threads or multiple vertical lines. The receiving groove is used to accommodate the material at the point where the plate 2 and the deformed part 112 are pressed together. The third connecting part 111 abuts against the inner wall of the multiple plates 2, and the receiving groove is used to accommodate the material of the inner wall of the plate 2.

[0074] When riveting sheet metal, those skilled in the art first place a nut 1. The position of the nut 1 varies depending on the actual processing location; it can be placed vertically or horizontally. Then, a third connecting portion 111 is provided on the outer wall of the nut 1, and multiple threads or vertical lines are provided on the third connecting portion 111. Next, multiple sheet metal plates 2 are stacked and simultaneously fitted onto the outer wall of the third connecting portion 111. Then, the upper and lower dies simultaneously compress both ends of the nut 2. The compression of the nut's ends by the upper and lower dies forms a deformation portion 112 on the third connecting portion 11. The deformation portion 112 is used to clamp the sheet metal plates 2.

[0075] Preferably, when a third connecting portion 111 is provided on the outer wall of the nut 1, a mounting hole 12 is provided at the middle position of the end of the main body portion 11 of the nut 1. The mounting hole 12 is a through hole, and a first connecting portion 121 and a second connecting portion 122 are respectively provided near both ends of the inner wall of the mounting hole 12. The first connecting portion 121 and the second connecting portion 122 enable the plate 2 to be fixedly connected to two external parts after riveting. Specifically, both the first connecting portion 121 and the second connecting portion 122 can be provided with threads, so that they can be threadedly connected to external parts.

[0076] In a further configuration of the nut 1, preferably, the thickness of the first connecting portion 121 is the same as the thickness of the second connecting portion 122, and when the third connecting portion 111 is configured, the ratio of the thickness of the third connecting portion 111 to the thickness of the first connecting portion 121 or the second connecting portion 122 is set to 1:2. During riveting, a smaller thickness of the third connecting portion 111 makes it more prone to deformation under stress. That is, setting the thickness of the third connecting portion 111 to be thinner than the thicknesses of the first connecting portion 121 and the second connecting portion 122 allows the deformable portion 112 to form in a shorter time, resulting in a more stable structure.

[0077] Although different specific embodiments are mentioned in this application, this application is not limited to the situations described in industry standards or embodiments. Slightly modified implementations based on certain industry standards or custom methods or embodiments can also achieve the same, equivalent, or similar, or predictable, implementation effects as the above embodiments. Embodiments applying these modified or modified data acquisition, processing, output, and judgment methods still fall within the scope of optional implementations of this application.

[0078] Although this application has been described by way of examples, those skilled in the art will know that this application has many modifications and variations without departing from the spirit of this application, and it is intended that the appended embodiments include these modifications and variations without departing from this application.
