The terms "first", "second", etc. in the specification and claims of this application or the above-mentioned drawings are used to distinguish different objects, not to describe a specific order.

[0039] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0040] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings.

[0041] Combine the following Figures 1 to 6 , describing an embodiment of the utility model.

[0042] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 6 As shown, the riveting head structure 1 of the present application includes a riveting head 11, a connecting piece 12, a first driving assembly 13 and a first fixed plate 14, the first driving assembly 13 is fixed on the first fixed plate 14, the riveting head 11 is fixed on the first driving assembly 13 through the connecting piece 12, the first driving assembly 13 is used to drive the connecting piece 12 and the riveting head 11 to move horizontally, the riveting head 11 includes a fixed frame 111, a first pressing block 112 and a second pressing block 113, the first pressing block 112 and the second pressing block 113 are fixed on the fixed frame 111, the end of the first pressing block 112 has a first end face 1121, the first end face 1121 is provided with at least two first protrusions 1122 arranged at intervals, and the first protrusions 1122 are evenly distributed at the edge of the first end face 1121.

[0043] Furthermore, the end of the second pressing block 113 has a second end surface 1131 , and the second end surface 1131 is provided with at least two second protrusions 1132 spaced apart from each other. The second protrusions 1132 are evenly distributed at the edge of the second end surface 1131 .

[0044] In this embodiment, the first driving assembly 13 is used to drive the riveting head 11 to move horizontally. By controlling the moving position of the riveting head 11, the automatic switching function of the first pressing block 112 and the second pressing block 113 is realized, and there is no need to manually replace the pressing blocks, thereby improving production efficiency.

[0045] In this embodiment, there is no limitation on the number of the first pressing block 112 and the second pressing block 113, and the number of the pressing blocks can be set according to actual needs. The first pressing block 112 and the second pressing block 113 are arranged adjacent to each other, and the structures of the first pressing block 112 and the second pressing block 113 can be the same or different. Preferably, the structures of the first pressing block 112 and the second pressing block 113 are different. The first pressing block 112 and the second pressing block 113 are respectively used for riveting openings of different shapes or sizes, which can increase the versatility of the riveting head 11. The shape and size of the first end face 1121 and the second end face 1131 are adapted to the shape and size of the opening to be riveted, and the first end face 1121 and the second end face 1131 can be circular, square or other shapes.

[0046] In this embodiment, evenly distributed first protrusions 1122 are provided on the edge of the first end face 1121 of the first pressure block 112. When the riveting head 11 is pressed down, the first protrusions 1122 contact the edge of the opening and exert pressure on the edge of the opening. The even distribution of the first protrusions 1122 makes the force on the edge of the opening uniform and is less prone to excessive deformation and cracks. In addition, the first protrusions 1122 are arranged at intervals. When the edge of the opening is deformed by force, the gaps between the first protrusions 1122 leave more deformation space for the edge of the opening, thereby preventing wrinkles from forming on the edge of the opening due to insufficient space.

[0047] In some embodiments not shown in the figure, the first end surface 1121 does not need to be provided with the first protrusion 1122 , and during the downward pressing process of the riveting head 11 , the first end surface 1121 directly contacts the edge of the opening and applies pressure to the edge of the opening.

[0048] In one embodiment, Figures 1 to 3 As shown, the first driving assembly 13 includes a first driving member 131, a slider 132 and a slide rail 133, the slide rail 133 extends in the horizontal direction and is fixed on the first fixing plate 14, the slider 132 is arranged on the slide rail 133, the connecting member 12 is fixed on the slider 132, the first driving member 131 is fixedly connected with the slider 132 or the connecting member 12, and the first driving member 131 is used to drive the slider 132 and the connecting member 12 to move along the slide rail 133. In this embodiment, the type of the first driving member 131 is not limited, and the first driving member 131 can be a motor, a cylinder or other power device.

[0049] In one embodiment, Figures 1 to 3As shown, the riveting head 11 also includes a first guide member 114 and a first limit member 115. The fixed frame 111 is provided with a first guide hole (not shown in the figure) extending in the vertical direction. The first guide member 114 passes through the first guide hole. One end of the first guide member 114 is fixedly connected to the connecting member 12, and the other end of the first guide member 114 is fixedly connected to the first limit member 115.
