[0016] The present utility model will be further explained and illustrated below in conjunction with the accompanying drawings and specific embodiments.

[0017] Embodiment: As shown in the figure, an automatic riveting device according to the present utility model includes a workbench 1, on which a feeding mechanism 2, a riveting mechanism 3 and a positioning mechanism 4 located between the two are provided. The feeding mechanism 2 includes a vibrating feeding tray 5, a bracket 6, a limit block 7 and a clamping mechanism 8.

The transmission part 11 and the clamping mechanism 8 are connected to an external drive. The clamping mechanism 8 is installed on the workbench 1 near the rotating disk 10. Below the workbench 1, a frame 12, a cabinet board 13, supporting feet 14 and universal rollers 15 are sequentially arranged. The frame 12 is of a frame structure, the cabinet board 13 is installed on the surface of the frame of the frame 12, and supporting feet 14 and universal rollers 15 are installed at the four corners of the bottom surface of the frame 12. Equally - spaced slot holes for riveting are provided on the rotating disk 10. The transmission part 11 drives the rotating disk 10 to rotate in the form of a gear belt, and the rotation angle of the rotating disk 10 each time is controlled by driving. Specifically, the corresponding rotation angle is set according to the number of slot holes for riveting on the rotating disk 10, so that each time it rotates, the slot holes can rotate to the next slot hole, facilitating the clamping mechanism 8 to automatically feed the parts for riveting to the riveting mechanism 3 for riveting and transporting them out.

[0018] The riveting mechanism 3 includes a fixing plate 16, a support frame 17, a moving frame 18, a positioning block 19, a positioning rod 20, a limiting rod 21, a riveting head 22, a driving member 23 and a clamping mechanism 8. The fixing plate 16 is installed on the other side of the workbench 1. The support frame 17 is vertically fixed on the fixing plate 16. The top end of the support frame 17 is slidably connected with the positioning rod 20 and the driving member 23. The lower ends of the positioning rod 20 and the driving member 23 are fixedly connected to the moving frame 18. The riveting head 22 is fixed in the moving frame 18 and its top is connected to the driving member 23. The limiting rod 21 is installed between the fixing plate 16 and the moving frame 18. A positioning block 19 connected to the fixing plate 16 is fixedly connected directly below the riveting head 22. The clamping mechanism 8 is installed on the fixing plate 16 and the support frame 17. During use, the positioning block 19 is located directly below the riveting head 22. When the riveting station of the rotating disc 10 rotates into place, the driving member 23 drives the moving frame 18 and the riveting head 22 to continuously press downwards, and with the positioning block 19 as the base, riveting is completed. During this process, the limiting rod 21 will limit the downward movement distance of the moving frame 18, making the downward pressure distance of the riveting head 22 controllable, that is, the pressing force magnitude can be controlled, preventing the riveting workpiece from being damaged by a large force.

[0019] The clamping mechanism 8 includes a base 24, a support 25, a horizontal moving member 26, a vertical moving member 27 and a pneumatic clamping jaw 28. The base 24 is connected to the workbench 1. The support 25 is vertically installed on the base 24. A horizontal moving member 26 is connected to one side of the top end of the support 25. The vertical moving member 27 is slidably connected to the horizontal moving member 26. The lower end of the vertical moving member 27 is installed with the pneumatic clamping jaw 28. The horizontal moving member 26 drives the vertical moving member 27 to move horizontally, and the vertical moving member 27 drives the pneumatic clamping jaw 28 to move up and down. The horizontal moving member 26, the vertical moving member 27 and the pneumatic clamping jaw 28 are connected to an external drive.

[0020] The horizontal moving member 26 consists of a connecting plate 29, a slide rail 30, a slider 31 and a driving cylinder 32. The connecting plate 29 is fixed to the support 25. The slide rail 30 is fixed inside the connecting plate 29. The slider 31 is slidably connected to the slide rail 30. The driving cylinder 32 is fixed on the connecting plate 29 and is connected to the slider 31, driving the slider 31 to move horizontally along the slide rail 30.

[0021] The vertical moving part 27 is composed of a main body 33, a telescopic rod 34, and a connecting plate 29. The main body 33 is connected to the horizontal moving part 26. The telescopic rod 34 is vertically slidably connected to the main body 33. The end of the telescopic rod 34 is fixedly connected to the connecting plate 29, and the connecting plate 29 is driven to move vertically by the telescopic rod 34. During use, the pneumatic clamping jaw 28 is driven by the connecting plate 29 to move up and down. While the vertical moving part 27 moves up and down, the pneumatic clamping jaw 28 can also freely open and close for clamping. During feeding, the horizontal moving part 26 and the vertical moving part 27 work synchronously to adjust the position, so that the pneumatic clamping jaw 28 is directly above the limit block 7, facilitating the clamping of the parts fed in the vibrating plate. After clamping, the vertical moving part 27 and the horizontal moving part 26 are controlled to move up and horizontally again, so that the clamped parts move towards the turntable 10. After arriving, it moves down again to release the pneumatic clamping jaw 28, and the riveting part is placed on the working position on the turntable 10 to complete the next processing. In this way, the cycle is repeated to complete automatic feeding and riveting.

[0022] The support feet 14 are adjustable support feet 14. During use, the height of the support legs can be finely adjusted according to the situation of the site, so that the four corners are supported on the ground stably, improving the flatness.

[0023] In this utility model, the parts for riveting are automatically fed to the positioning mechanism by the feeding mechanism, and then transported to the turntable by the clamping mechanism. After rotation and movement, the combined and formed riveting part is rotated to directly below the riveting mechanism for riveting and forming. During the process, the positioning block can provide lower support, and the limiting rod can position and limit the riveting mechanism, so that the riveting part is aligned with the working connection hole. Each component in the clamping mechanism can work independently without interference, and can achieve fast moving and clamping, improving the riveting efficiency and riveting quality.
