[0024] Example:

[0025] like Figure 1-3 As shown, this embodiment proposes a riveting screw device for an electric adjustment gear mounting bracket of a car seat, comprising a lower foot 10, a lower die seat 13 is arranged on the lower foot 10, and an upper die seat 50 is arranged on the lower die seat 13;

[0026] The upper die base 50 is provided with a pressing plate 54, and a pressing positioning insert 40 is provided on the pressing plate 54. The lower die base 13 is provided with a lower template 17, and a bracket 60 is provided on the lower template 17. The lower template 17 is provided with a riveting die 20, and the riveting die 20 matches the position of the pressing positioning insert 40. A riveting assembly 30 is provided between the riveting die 20 and the pressing positioning insert 40. A top plate 14 that moves up and down is provided in the lower foot 10, and a plurality of positioning top rods 15 are provided on the top plate 14. The positioning top rods 15 extend into the lower template 17, and the bracket 60 is provided on the positioning top rod 15. The positioning top rod 15 is lifted to drive the bracket 60 to separate from the lower template 17.

[0027] In this embodiment, when pressing the screw into the bracket 60, the bracket 60 is placed on the lower template 17, and then the upper die seat 50 drives the pressure plate 54 to descend, so that the pressure positioning insert 40 is displaced toward the riveting die 20, and the screw is pressed into the bracket 60 through the riveting assembly 30, and then the upper die seat 50 drives the pressure plate 54 to lift, so that the pressure plate 54 is separated from the bracket 60, and then the ejector plate 14 is displaced toward the upper die seat 50, so that the positioning ejector rod 15 contacts the bracket 60, and the bracket 60 is lifted up, so that the bracket 60 is separated from the lower template 17, and at the same time, the screw on the bracket 60 is detached from the riveting die 20;

[0028] The lower die base 13 cooperates with the upper die base 50 and the ejector plate 14 and the positioning ejector rod 15 that move up and down in the lower foot 10 to achieve accurate positioning and stable riveting of the bracket 60. The upper die base 50 drives the pressing plate 54 to descend, accurately guides the docking of the pressing positioning insert 40 with the riveting die 20, and fixes the screw to the bracket 60 through the riveting assembly 30. Subsequently, the upper die base 50 guides the pressing plate 54 to rise, cooperates with the displacement of the ejector plate 14 and the action of the positioning ejector rod 15, and realizes the rapid lifting of the bracket 60 and the smooth disengagement of the screw, thereby improving the assembly efficiency, ensuring the assembly quality, reducing the error and loss during the operation, and enhancing the overall performance and reliability of the product. At the same time, it overcomes the defects of the original riveting device using the elastic element discharge method, which will cause the product to be unable to pop out after riveting and cause the thread to be damaged due to the small matching clearance during riveting, thereby improving production efficiency and practicality.

[0029] Specifically, a lower bottom plate 11 is disposed at the bottom end of the lower foot 10 , a lower pad 16 is disposed on the lower die base 13 , and the lower pad 16 is disposed between the lower die base 13 and the lower die plate 17 .

[0032] The upper cover plate 51 , the fixing plate 52 , and the mounting plate 53 are arranged in sequence from top to bottom.

[0033] In this embodiment, the upper cover plate 51, the fixing plate 52 and the mounting plate 53 are arranged between the upper mold base 50 and the pressing plate 54 to form a multi-level protective structure, which can protect the internal mechanical components from external environmental pollution, such as dust, debris, etc., and extend the service life of the equipment.

[0034] Specifically, the riveting assembly 30 includes a riveting punch 34 , which is connected to the fixing plate 52 . The riveting punch 34 passes through the mounting plate 53 and the pressing plate 54 in sequence, and the position of the riveting punch 34 matches the riveting die 20 .

[0035] In this embodiment, by providing a riveting punch 34 , when the riveting assembly 30 moves downward, the riveting punch 34 can be driven downward to squeeze the screw so that the screw is positioned on the bracket 60 .

[0036] Specifically, the riveting assembly 30 also includes a screw positioning sleeve 32 , the riveting die 20 is provided with a positioning hole 33 , a positioning spring 31 is also provided in the positioning hole 33 , the screw positioning sleeve 32 is arranged in the positioning hole 33 , and the screw positioning sleeve 32 is connected to the positioning spring 31 .

[0037] In this embodiment, when pressing the screw in, the screw is placed on the bracket 60, and the tail of the screw is allowed to enter the screw positioning sleeve 32. Then the riveting punch 34 is lowered to press the screw into the bracket 60. At the same time, the screw is pressed into the positioning hole 33 until the screw is crimped onto the bracket 60. During the pressing process, the screw positioning sleeve 32 is displaced so that the positioning spring 31 is compressed and contracted. When the riveting punch 34 is lifted, the positioning spring 31 and the positioning ejecting rod 15 simultaneously lift the screw to facilitate the bracket 60 to detach from the lower template 17.

[0038] Specifically, the screw positioning sleeve 32 is slidably disposed in the positioning hole 33 ; the lower template 17 , the pressing plate 54 and the bracket 60 are adapted to each other.

[0039] In this embodiment, the lower template 17, the pressing plate 54 and the bracket 60 are adapted to each other, so that deformation of the bracket 60 when the screw is pressed in can be avoided.

[0040] Specifically, a guide column 55 is disposed on the upper cover plate 51 . The guide column 55 passes through the lower template 17 . The guide column 55 is slidably matched with the lower template 17 .

[0041] In this embodiment, the guide column 55 can facilitate the temperature displacement of the upper cover plate 51 .
