The following describes the implementation method of the present utility model based on its overall structure.

[0034] Reference Figure 1 As shown, the embodiment of the present application provides a riveting structure, including:

[0035] The main body 1 comprises a first connecting portion 11 and a second connecting portion 12, wherein the outer diameter of the first connecting portion 11 is greater than the outer diameter of the second connecting portion 12;

[0036] A first hole 111 is formed in the first connection portion 11, and a second hole 121 is formed in the second connection portion 12. The first hole 111 and the second hole 121 are connected to each other, and the end of the second hole 121 away from the first hole 111 is closed. The inner walls of the first hole 111 and the second hole 121 are both provided with threads.

[0037] A plate 2 is sleeved on the outer wall of the second connecting portion 12, and the inner diameter of the plate 2 is smaller than the outer diameter of the first connecting portion 11;

[0038] A flange portion 122 is provided on the side wall of the second connection portion 12 away from the first connection portion 11. The flange portion 122 is deformed toward the direction of the plate to contact the plate 2.

[0039] The first hole 111 and the second hole 112 are both threadedly connected to the studs, and the inner wall of the second hole 121 is deformed toward the direction of the first hole 111 until the wall of the plate facing the first connection portion 11 contacts the first connection portion 11 .

[0040] according to Figure 1 , those skilled in the art set the main body 1 and the plate 2 to be riveted. Specifically, the main body 1 includes a first connecting portion 11 and a second connecting portion 12. It can be understood that the outer diameter of the second connecting portion 12 is smaller than the first connecting portion 11. The plate 2 can be sleeved on the outer wall of the second connecting portion 12.

[0041] Further, those skilled in the art may respectively set a first hole 111 and a second hole 121 in the first connection portion 11 and the second connection portion 12. The first hole 111 and the second hole 121 are connected. In one embodiment, preferably, the first hole 111 and the second hole 121 have the same aperture. Threads for connection are provided in the first hole 111 and the second hole 121. That is, the first hole 111 and the second hole 121 can be threadedly connected with the connection stud.

[0042] In this embodiment, the second hole 121 is closed and arranged away from the end side of the first hole 111. Figure 1 In the case where the first hole 111 is connected to the second hole 121 , the first hole 111 and the second hole 121 form a blind hole for connecting the main body 1 .

[0043] In the above-mentioned arrangement structure, the main body 1 can be directly threadedly connected to the connecting stud through the blind hole, thereby avoiding the overflow of debris during riveting.

[0044] A flange portion 122 is provided on the side wall of the second connection portion 12 away from the first connection portion 11. During the riveting process, an external force toward the position of the first connection portion 11 can be applied to the flange portion 122. Under the action of the external force, the flange portion 122 is deformed toward the position of the plate 2. During the deformation process, the flange portion 122 approaches the plate 2 until the flange portion contacts the plate 2.

[0045] It is understandable that, in the above process, the second connection part 12 may be deformed under the action of external force. In the deformation process, the second connection part 12 approaches the position of the first connection part 11 until the plate 2 contacts the first connection part 11 .

[0046] In the above-mentioned embodiment, the side wall of the plate 2 facing the first connection portion 11 abuts against the first connection portion 11 , and the side wall of the plate 2 away from the first connection portion 11 abuts against the flange portion 122 .

[0047] In the above-mentioned embodiment, during the deformation process of the second connection portion 12 , the thread in the second hole 121 of the second connection portion 12 may fail due to extrusion fracture.

[0048] The first hole 111 is formed by effective threads, and the second hole 121 includes effective threads and guide threads. During installation, the guide threads can be axially compressed to cause the second hole 121 to deform axially and radially, and then riveted together with the plate 2 to generate torque and axial force.

[0049] The outer diameter of the first connection part 11 is greater than the outer diameter of the second connection part 12, and the inner diameters of the first hole 111 and the second hole 121 are the same. That is, the thickness of the first connection part 11 is greater than the thickness of the second connection part 12. When an external force is applied to the flange part 122 and the second connection part 12, the first connection part 11 can maintain a stable structure.

[0050] In summary, after the riveting process is completed, the second connection part 12 is deformed, and the first connection part 11 remains stable, so that the plate 2 can be stably connected. Among them, the arrangement of the first hole 111 and the second hole 121 forming a blind hole can squeeze and store the debris generated during the deformation. This can not only improve the strength of the connection after riveting, but also avoid the interference of the debris on the external parts after riveting.

[0051] In the above structure, the inner wall of the plate 2 contacts the outer wall of the second connecting portion 12. Preferably, the inner wall of the plate 2 is recessed toward the edge of the plate 2 to form a receiving groove 21 for accommodating the material of the outer wall of the second connecting portion 12.

[0052] With the above structure, when the second connection part 12 is subjected to external force, the second connection part 12 is deformed. During the deformation of the second connection part 12, the material of the outer wall of the second connection part 12 is squeezed into the receiving groove 21, thereby forming a structure in which the outer wall of the second connection part 12 and the receiving groove 21 of the inner wall of the plate 2 accommodate and resist each other.

[0053] In the above structure, the outer wall of the second connecting portion 12 and the inner wall groove 21 of the plate 2 resist each other, thereby effectively preventing the plate 2 from rotating during operation, thereby effectively improving the stability of the riveting of the plate 2.

[0054] More preferably, a plurality of grooves 21 are provided on the inner wall of the plate 2, and the plurality of grooves 21 are symmetrically spaced. That is, a person skilled in the art can provide a plurality of grooves 21 in the plate 2. The plurality of grooves 21 can simultaneously accommodate the material on the outer wall of the second connecting portion 12. This can further make the structure of the plate 2 more stable after riveting. The plurality of grooves 21 are symmetrically spaced, so that the force on the plurality of grooves 21 on the plate 2 can be more uniform.

[0055] In the further setting of the flange portion 122, preferably, the outer diameter of the flange portion 122 is equal to the outer diameter of the second connection portion 12, and the maximum outer diameter of the second connection portion 12 is equal to or less than the inner diameter of the plate 2. In the above-mentioned embodiment, the flange portion 122 approaches the position of the plate 2 under the action of external force and contacts the plate 2. In this embodiment, the outer diameter of the flange portion 122 is equal to the outer diameter of the second connection portion 12, and the maximum outer diameter of the second connection portion 12 is equal to or less than the inner diameter of the plate 2. In this way, the plate 2 can be stably mounted on the outer wall of the second connection portion 12. In this way, the riveted structure of the plate 2 is more stable.

[0056] In the above embodiment, the first connection part 11 and the second connection part 12 are connected and preferably, the middle position of the first connection part 11 and the second connection part 12 is located on the same straight line. Thus, the main body 1 will not be subjected to eccentric force during the riveting process, thereby effectively avoiding the riveting failure of the main body 1.

[0057] Preferably, the first connection part 11 and the second connection part 12 are an integrated structure. In the process of riveting the main body 1 and the plate 2, the integrated first connection part 11 and the second connection part 12 can make the structure of the main body 1 more stable, and thus can make the main body 1 withstand greater external force during riveting.

[0058] It is understandable that, in one embodiment, preferably, the first connection portion 11 is fixedly connected to the second connection portion 12. The first hole 111 and the second hole 121 can be connected to each other, so that the debris generated during riveting can be received by the first hole 111 and the second hole 121.

[0059] In the process of riveting the main body 1 and the plate 2, preferably, the first connection part 11 is installed in the lower mold 3, and the flange part 122 is installed on the upper mold 4, or the upper mold 3 is provided with a positioning groove, and the flange part 122 is installed in the positioning groove. In addition, an external force can be applied to the flange part during the process of closing the upper mold 4 and the lower mold 3, and at the same time, the first connection part 11 can maintain a constant relative position, thereby making the riveting process more stable.

[0060] Preferably, the edge of the flange portion 122 extends in a direction away from the location of the second hole 121 to form a groove. Figure 1 , the edge of the flange portion 122 is extended to form a groove. Therefore, when a person skilled in the art applies an external force to the flange portion 122, the flange portion 122 can be stably deformed. Furthermore, during the deformation of the flange portion 122, the side wall of the second hole 121 away from the first hole 111 will remain stable, thereby effectively accommodating debris.

[0061] In the above embodiment, preferably, the main body 1 is made of aluminum, copper or low carbon steel, and the plate 2 is made of stainless steel or low alloy structural steel. Thus, the main body 1 can be plastically deformed during the riveting process, while the plate can be kept from being deformed. Thus, the riveted structure can be made more stable, and the connection between the riveted structure and other external parts will not be affected.

The embodiments of data acquisition, processing, output, judgment methods, etc. after these modifications or deformations can still fall within the scope of the optional implementation plans of this application.

[0063] Although the present application has been described through embodiments, those skilled in the art will appreciate that there are many modifications and changes to the present application without departing from the spirit of the present application. It is intended that the attached embodiments include these modifications and changes without departing from the present application.
