[0002] The semi-automatic nut-box riveting machine is a specialized piece of equipment for securely fixing nuts to workpieces such as boxes. It utilizes specific riveting techniques, applying pressure and force to cause plastic deformation of the sheet metal material, thereby pressing the nut into a pre-drilled hole to form a reliable mechanical connection. This equipment is suitable for materials such as low-carbon steel and aluminum alloy sheets, and is widely used in automotive manufacturing, aerospace, and electronics industries. It can improve production efficiency, reduce manual labor, lower production costs, and ensure the stability and consistency of the connection.

When the screw 7 rotates, the height of the support plate 3 can be adjusted through the lifting frame 6, thereby facilitating the placement of the elbow. The top of the base 2 is provided with a seat adjustment mechanism.

[0024] refer to Figure 3The seat adjustment mechanism includes a fixed block 9 fixedly connected to the top of the base 2. A sliding plate 10 is slidably connected to the inner wall of the fixed block 9. The sliding plate 10 can slide to the left inside the fixed block 9, thereby adjusting the left and right positions of the sliding plate 10.

[0025] As a technical optimization of this utility model, by setting up a lifting support mechanism, the left and right positions of the seat (cushion 13) can be adjusted to adapt to the usage habits and operating space requirements of different operators; at the same time, the threaded connection between the screw 11 and the lifting ring 14 can realize the adjustment of the seat height, further improving the adaptability and comfort of the seat.

The connecting cylinder 24 can drive the internal gear cylinder 23 to slide to the left on the surface of the transmission rod 18, so that the internal gear cylinder 23 and the linkage gear 22 mesh with each other, thereby driving the linkage rod 19 to rotate.

[0029] As a technical optimization of this utility model, by setting a clutch mechanism, when the linkage rod 19 needs to rotate, the internal gear cylinder 23 is engaged with the linkage gear 22; when not needed, the internal gear cylinder 23 can be disengaged from the linkage gear 22, avoiding unnecessary power transmission and improving the power usage flexibility and safety of the device.

[0032] refer to Figure 3 The bottom of the sliding plate 10 is fixedly connected with four rollers 29, which can support the sliding plate 10.

[0033] As a technical optimization of this utility model, by setting the roller 29, the friction between the sliding plate 10 and the fixed block 9 is greatly reduced, making the sliding plate 10 slide more smoothly when sliding left and right, reducing the difficulty of operation, and improving the efficiency of adjusting the left and right position of the seat.

[0034] The working principle and usage process of this utility model: This device is designed around the riveting machine 1, aiming to provide functions such as lifting support and seat adjustment to improve the convenience and comfort of riveting operation. The dual-axis motor 16 serves as the power source. The right output end drives the screw 7 to rotate via a bevel gear 17. The screw 7 is threadedly connected to the lifting frame 6, and both ends of the screw 7 are fixed to the fixed column 8 connected to the bottom of the riveting machine 1 via bearings. Therefore, when the screw 7 rotates, the lifting frame 6 moves up and down along it, thereby driving the support plate 3 to rise and fall, allowing the operator to adjust the height of their elbows as needed. The left output end drives the screw 11 to rotate via a transmission rod 18 and a bevel gear 21. The screw 11 is threadedly connected to the lifting ring 14 fixed to the bottom of the support plate 12. The top of the support plate 12 is connected to the seat cushion 13. Therefore, when the screw 11 rotates, the lifting ring 14 moves up and down along it, driving the support plate 12 and seat cushion 13 to adjust their height to meet the needs of different operators. Meanwhile, the sliding plate 10 can slide to the left within the fixed block 9, thereby adjusting the left and right positions of the seat cushion 13. Regarding the clutch mechanism, when it is necessary to rotate the linkage rod 19, the handle 28 drives the stabilizing frame 26 and the linkage ring 25 to move to the left. The linkage ring 25 drives the connecting cylinder 24 to slide to the left, and the connecting cylinder 24 then drives the internal gear cylinder 23 to slide to the left on the surface of the transmission rod 18, causing the internal gear cylinder 23 to mesh with the linkage gear 22. At this time, the left transmission rod 18 of the dual-shaft motor 16 drives the linkage gear 22 and the linkage rod 19 to rotate through the internal gear cylinder 23, realizing the transmission or disconnection of power. Furthermore, the protective box 27 is fixedly connected to the top of the base 2, which can shield and protect the clutch mechanism; the four rollers 29 at the bottom of the sliding plate 10 roll on the top of the base 2, providing support for the sliding plate 10 and making its sliding smoother. This avoids the inconvenience and discomfort caused by the inability of the nut riveting machine 1 to adjust the height of the seat and elbow support plate 3, giving it the advantage of ease of use.

[0035] In summary, when this utility model is used, the height of the seat and support plate 3 can be quickly adjusted under the action of the lifting support mechanism, seat adjustment mechanism, drive mechanism and clutch mechanism, avoiding the inconvenience and discomfort caused by the inability of the nut riveting machine 1 to adjust the height of the seat and elbow support plate 3, thus giving it the advantage of being easy to use.
