[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. The described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] Reference Figures 1-4 A servo riveting device includes a base 1. An adjusting frame 7 is bolted to one side of the base 1. A support plate is bolted to one side of the adjusting frame 7. A drive motor 6 is bolted to the upper surface of the support plate. A lifting screw 17 is bolted to one end of the output shaft of the drive motor 6 via a coupling. A movable frame is slidably connected inside the adjusting frame 7. A riveting machine 8 is bolted to the movable frame. The lifting screw 17 passes through the movable frame and is threadedly connected to it. A grating ruler 19 is bolted to both sides of the adjusting frame 7. A limit switch 18 is bolted to one side of the grating ruler 19, and the limit switch 18 is electrically connected to the grating ruler 19 and the drive motor 6. An adjustment assembly for changing the product position is provided at the bottom of the base 1. The product is placed on the placement platform 16, and then the drive motor 6 is started. The drive motor 6 drives the lifting screw 17 to rotate. During the rotation, the lifting screw 17 drives the moving frame to move up and down through the threaded engagement with the moving frame. The moving frame drives the riveting machine 8 to move. During the movement of the riveting machine 8, the grating ruler 19 measures the distance the riveting machine 8 moves. When the riveting machine 8 moves to the designated position, the grating ruler 19 sends a signal to the limit switch 18, which shuts off the drive motor 6, thereby allowing the riveting machine 8 to move in a position. At the same time, the movement of the riveting machine 8 driven by the lifting screw 17 can make the riveting machine 8 move accurately, improving the quality of the riveted product.

[0024] In this utility model, the adjustment assembly includes a fixed frame 9, which is fixed to the bottom of the base 1 by bolts. Two guide rails 12 are fixed inside the fixed frame 9 by bolts, and a slide 4 is slidably connected to the outer sides of the two guide rails 12. A power assembly one for driving the slide 4 to move is provided inside the fixed frame 9. Two slide rails are fixed inside the slide 4 by bolts, and a placement platform 16 is slidably connected to the outer sides of the two slide rails. A power assembly two for driving the placement platform 16 to move is provided inside the slide 4. The power assembly one includes a longitudinal adjusting screw 11, which is rotatably connected to the fixed frame 9 via a bearing. The longitudinal adjusting screw 11 passes through the slide 4 and is threadedly connected to the slide 4. A longitudinal adjusting motor 10 is fixed to one side of the fixed frame 9 by bolts. One end of the output shaft of the longitudinal adjusting motor 10 passes through the fixed frame 9 and is fixed to the longitudinal adjusting screw 11 via a coupling. The power assembly two includes a transverse adjusting screw 15, which rotates... Connected within the slide 4, the lateral adjustment screw 15 passes through the placement platform 16 and is threadedly connected to it. A lateral adjustment motor 13 is bolted to one side of the slide 4, and a gearbox 14 is bolted to the other side of the slide 4. The output shaft of the lateral adjustment motor 13 is fixed to the input shaft of the gearbox 14 via a coupling, and the output shaft of the gearbox 14 is fixed to the lateral adjustment screw 15 via a coupling. After riveting one point of the product, the longitudinal adjustment motor 10 is started to drive the longitudinal adjustment screw 11 to rotate. The longitudinal adjustment screw 11 drives the slide 4 to move along the guide rail 12. At the same time, the lateral adjustment motor 13 is started, and the lateral adjustment motor 13 drives the lateral adjustment screw 15 to move through the gearbox 14. The lateral adjustment screw 15 drives the placement platform 16 to move along the slide rail, thereby changing the position of the product. This allows for multi-point riveting of the product, improving the working efficiency of the riveting equipment.

[0025] In particular, a second telescopic dust cover 20 is bonded inside the fixed frame 9 to cover the longitudinal adjusting screw 11. The second telescopic dust cover 20 can prevent dust from entering the fixed frame 9 and adhering to the longitudinal adjusting screw 11. A first telescopic dust cover 5 is bonded inside the slide 4 to cover the transverse adjusting screw 15. The first telescopic dust cover 5 can prevent dust from entering the slide 4 and adhering to the transverse adjusting screw 15. A protective cover 2 is fixed to the outside of the adjusting frame 7 by bolts. Multiple heat dissipation holes 3 are opened on the outside of the protective cover 2. The protective cover 2 covers the drive motor 6 and the grating ruler 19, thereby preventing the drive motor 6 and the grating ruler 19 from being damaged by collisions with external objects, thus improving the service life of the riveting equipment. The heat dissipation holes 3 can dissipate the heat generated by the drive motor 6 and the grating ruler 19 inside the protective cover 2.

[0026] Working principle: When needed, place the product on the placement platform 16, then start the drive motor 6. The drive motor 6 will drive the lifting screw 17 to rotate. During the rotation, the lifting screw 17 will drive the moving frame to move up and down through the threaded engagement with the moving frame. The moving frame will drive the riveting machine 8 to move. During the movement of the riveting machine 8, the grating ruler 19 will measure the distance the riveting machine 8 moves. When the riveting machine 8 moves to the designated position, the grating ruler 19 will send a signal to the limit switch 18, which will shut off the drive motor 6, thereby allowing the riveting machine 8 to move in a positioning position. At the same time, the lifting screw 17 will move up and down through the threaded engagement with the moving frame. The lead screw 17 drives the riveting machine 8 to move, enabling precise movement of the riveting machine 8 and improving the quality of the riveted finished product. After riveting one point of the product, the longitudinal adjustment motor 10 is started to drive the longitudinal adjustment lead screw 11 to rotate. The longitudinal adjustment lead screw 11 drives the slide 4 to move along the guide rail 12. At the same time, the transverse adjustment motor 13 is started. The transverse adjustment motor 13 drives the transverse adjustment lead screw 15 to move through the gearbox 14. The transverse adjustment lead screw 15 drives the placement table 16 to move along the slide rail, thereby changing the position of the product. This allows for multi-point riveting of the product, improving the working efficiency of the riveting equipment.

[0027] Finally, it should be noted that those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
