[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Reference Figures 1-3An embodiment of this utility model provides an automatic positioning riveting machine, including a machine body 1, a support platform 2 fixedly connected to the front side of the machine body 1, a vibratory plate 3 installed on the upper part of the support platform 2, a feeding port 4 opened on one side of the inside of the vibratory plate 3, a guide rail 5 fixedly connected to one side of the vibratory plate 3, the feeding port 4 and the guide rail 5 communicating with each other, a material seat 6 fixedly connected to the bottom of one side of the guide rail 5, an electric push rod 7 fixedly connected to the inside of the material seat 6 near the vibratory plate 3, a push plate 8 fixedly connected to the output end of the electric push rod 7, a blocking component rotatably connected inside the material seat 6, the blocking component is used to block the rivets to prevent them from falling out of the material seat 6, and the push plate 8 is slidably connected inside the material seat 6.

[0032] The blocking assembly includes a rotating plate 9, which is rotatably connected to the inside of the side away from the electric push rod 7 by a positioning pin. A spring 10 is fixedly connected to the side of the rotating plate 9 away from the electric push rod 7, and the other end of the spring 10 is fixedly connected to the inner wall of one side of the material seat 6.

[0033] By activating the vibratory feeder 3, the internal rivets are fed into the guide rail 5 through the feed port 4, where they are conveyed and then fall into the material seat 6. The rotating plate 9 blocks the rivets, preventing them from falling out of the material seat 6. Then, the electric push rod 7 is activated, which drives the push plate 8 to push the internal rivets, which simultaneously push and squeeze the rotating plate 9, causing the rotating plate 9 to rotate and squeeze the spring 10, which stores energy to generate a rebound force. When the rotating plate 9 rotates and no longer blocks the rivets, they fall into the material installed in the positioning mold 13. This achieves efficient, stable, and automated conveying and installation of rivets, improving production efficiency and product quality. When the electric push rod 7 retracts, the rotating plate 9 is no longer squeezed and rotates under the rebound force of the spring 10, closing the material seat 6 again.

[0034] Reference Figure 1 , Figure 4 , Figure 5 A drive device 12 is installed on the upper part of the machine body 1. A rotating disk 11 is fixedly connected to the output end of the drive device 12. A uniformly distributed positioning mold 13 is installed on the upper part of the rotating disk 11. A support frame 16 is fixedly connected to the upper right side of the machine body 1. A cylinder 17 is fixedly connected to the upper part of the support frame 16. A movable plate 18 is fixedly connected to the output end of the cylinder 17. An electric push rod 21 is installed on the left side of the movable plate 18. A connecting plate 22 is fixedly connected to the output end of the electric push rod 21. A pressure head 23 is installed at the bottom of the connecting plate 22. Telescopic rods 19 are fixedly connected to the front and rear of the right side of the movable plate 18. A slide rail 20 is fixedly connected to the bottom of the movable plate 18. The connecting plate 22 is slidably connected inside the slide rail 20.

[0035] The upper part of the machine body 1 is equipped with lower cylinders 14 evenly distributed around the diameter of the rotating disk 11. The output end of the lower cylinder 14 is fixedly connected to a connecting block 15, which is attached to the bottom of the positioning mold 13. The upper left side of the machine body 1 is equipped with a controller 24, which is electrically connected to the vibrating disk 3, electric push rod 7, cylinder 17, electric push rod 21 and lower cylinder 14.

[0036] After the rivet enters the pre-drilled hole in the material, the drive device 12 is started, which drives the rotating disk 11 to move the unriveted material under the pressure head 23. Then, the cylinder 17 is started, which moves the movable plate 18 downward via the piston rod. The stability of the movable plate 18 during movement is ensured by the telescopic rod 19. The electric push rod 21 is then started, which pushes the connecting plate 22 to slide inside the slide rail 20. Under the action of the cylinder 17 and the electric push rod 21, the connecting plate 22 is aligned with the material size in the positioning mold 13. The device is moved to effectively position the rivet and lower the pressure head 23 to press it into the hole in the material. During the riveting process, the rivet leg is stretched and forms a fixed riveting point. This not only improves the efficiency and accuracy of riveting but also ensures the reliability and safety of the positioning structure. Through automation and mechanization, human error is reduced, production efficiency is improved, and the skill requirements for operators are lowered. The rotating disk 11 is supported by the lower cylinder 14 and the connecting block 15 at the bottom of the rotating disk 11 to keep it balanced.

[0037] Working principle: When the device is needed, the vibratory feeder 3 is activated, allowing the internal rivets to enter the guide rail 5 through the feed port 4 for conveying. The rivets then fall into the material seat 6, where the rotating plate 9 blocks them, preventing them from falling out. Subsequently, the electric actuator 7 is activated, driving the push plate 8 to push the rivets, simultaneously rotating the rotating plate 9. This causes the rotating plate 9 to compress the spring 10, storing force to generate a rebound force. When the rotating plate 9 no longer blocks the rivets, they fall onto the material inside the positioning mold 13. After the rivet enters the pre-set hole in the material, the drive device 12 is started, which drives the rotating disk 11 to turn the unriveted material under the pressure head 23. Then, the cylinder 17 is started, which drives the piston rod to push the movable plate 18 down. The telescopic rod 19 ensures the stability of the movement of the movable plate 18. At the same time, the electric push rod 21 is started, which pushes the connecting plate 22 to slide in the slide rail 20, so that the connecting plate 22 moves according to the material size in the positioning mold 13, effectively positioning the material. The pressure head 23 is then moved down to press the rivet into the hole in the material.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, 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 the present utility model should be included within the protection scope of the present utility model.
