[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0024] See also Figure 1-4 , the utility model provides a technical solution:

[0025] Embodiment 1: A rivet automatic feeding and riveting device includes a base 1, a conveyor belt 3 is provided on the top of the base 1, a feeding pipe 6 is fixedly connected to the top of the base 1, one end of the conveyor belt 3 passes through the feeding pipe 6 and extends into the feeding pipe 6, an outer side wall of the feeding pipe 6 is fixedly connected to an electric push rod 4, an output end of the electric push rod 4 is fixedly connected to a push plate 5, a shell 7 is fixedly connected to the top of the base 1, a rotating plate 8 is rotatably connected inside the shell 7, a rotating shaft 10 is fixedly connected inside the rotating plate 8, and a motor 9 is fixedly connected to the bottom of the base 1, the rotating shaft 10 is fixedly connected to the output end of the motor 9, a plurality of discharge troughs 11 are provided inside the rotating plate 8, a feed trough 12 is provided on one side of the shell 7, the feed trough 12 corresponds to the discharge trough 11 and the feeding pipe 6 respectively, a plurality of rivets 13 are provided inside the rotating plate 8, the rivets 13 are slidably connected to the conveyor belt 3 and the feeding pipe 6, and the rivets 13 correspond to the discharge trough 11 and the feed trough 12 respectively.

[0026] The rivet 13 is transported to the feed pipe 6 via the conveyor belt 3. Next, the electric push rod 4 is started. After the electric push rod 4 starts running, it pushes the push plate 5 to move. The push plate 5 will push the rivet 13 to the end of the feed pipe 6. The rivet 13 enters the discharge trough 11 opened inside the rotating plate 8 through the feed trough 12 on the side of the shell 7. The motor 9 is started, and the motor 9 drives the rotating plate 8 on the rotating shaft 10 to start rotating. During the rotation of the rotating plate 8, the rivet 13 will be positioned between the discharge trough 11 and the shell 7. The mutual cooperation between these components achieves the effect of rapid loading. Compared with traditional loading methods, this design can more efficiently transport rivets to the specified position, thereby improving work efficiency.

[0027] Example 2: The difference between this example and Example 1 is that, the top of the base 1 is fixedly connected to a slide rail 14, the outside of the slide rail 14 is slidably connected to a workbench 15, a locking screw 16 is provided on one side of the workbench 15, a pair of fixed frames 17 are fixedly connected to the top of the workbench 15, each fixed frame 17 is slidably connected to a slide rod 20, a limit ring 18 is fixedly connected above the slide rod 20, and a spring 19 is fixedly connected between the limit ring 18 and the fixed frame 17, and a pressure plate 2 is fixedly connected to the bottom of the slide rod 20 1. The spring 19 is sleeved on the outer wall of the slide rod 20. The top of the base 1 is fixedly connected to the support plate 2. The outer wall of one side of the support plate 2 is fixedly connected to the motor 23. The output end of the motor 23 is fixedly connected to the threaded rod 24. The outer wall of the threaded rod 24 is threadedly connected to the connecting block 25. The outer wall of the connecting block 25 is fixedly connected to the connecting plate 22. The outer wall of the connecting plate 22 is fixedly connected to the pressure block 27. The output end of the pressure block 27 is fixedly connected to the automatic clamping mechanism 28. The outer wall of the connecting plate 22 is fixedly connected to the hydraulic cylinder 26.

[0028] Pulling up the slide bar 20 inside the fixed frame 17 puts the spring 19 between the fixed frame 17 and the retaining ring 18 into a stretched state, and simultaneously pulls up the pressure plate 21 at the bottom of the slide bar 20. Next, place the workpiece on the workbench 15, with the two corners of one end of the workpiece resting on the bottom of the fixed frame 17. Release the slide bar 20. The spring 19, due to its elasticity, will drive the slide bar 20 downward, which in turn drives the pressure plate 21 downward, thereby positioning the workpiece. Through the coordination of these components, a rapid positioning effect is achieved. According to the corresponding position of the automatic clamping mechanism 28, the workbench 15 is pushed to slide on the slide rail 14, and then locked using the locking screw 16. Next, start the motor 23 outside the support plate 2. The motor 23 drives the threaded rod 24 to rotate. The rotation of the threaded rod 24 causes the connecting plate 22 on the connecting block 25 to move left and right. When the connecting plate 22 moves, it also drives the pressure block 27 and the hydraulic cylinder 26 to move. When the hydraulic cylinder 26 moves to the corresponding position on the housing 7, the rivet 13 is grabbed by the hydraulic cylinder 26 and then moved to the workpiece above the workbench 15. At this time, the activation of the pressure block 27 drives the automatic clamping mechanism 28 to move downward and press the rivet 13 onto the workpiece.

[0029] Working principle: first, the rivet 13 is transported to the feeding pipe 6 through the conveyor belt 3, and the electric push rod 4 is started. Under the action of the electric push rod 4, the push plate 5 is pushed to move and the rivet 13 is pushed to the end, and enters the discharge trough 11 opened in the rotating plate 8 through the feed trough 12 on the side of the shell 7. At this time, the motor 9 is started, and the rotating plate 8 on the rotating shaft 10 is driven to rotate under the action of the motor 9. When the rotating plate 8 rotates, the rivet 13 will be positioned between the discharge trough 11 and the shell 7. Through the cooperation between them, the effect of fast feeding is achieved, which improves the working efficiency. The sliding rod 20 inside the fixed frame 17 is pulled up, so that the spring 19 between the fixed frame 17 and the limit ring 18 is in the tensioning device, and the pressure plate 21 at the bottom of the sliding rod 20 is pulled up. At this time, the workpiece is placed on the workbench 15, and the two corners of one end of the workpiece are placed on the bottom of the fixed frame 17 respectively. The sliding rod 20 is released through the spring. The elasticity of the spring 19 will drive the slide bar 20 to move down, thereby driving the pressure plate 21 to move down and position the workpiece. Through the cooperation between them, the effect of rapid positioning is achieved. At this time, according to the corresponding position of the automatic clamping mechanism 28, the worktable 15 is pushed to slide on the slide rail 14 and locked by the locking screw 16. At this time, the motor 23 outside the support plate 2 is started, and the threaded rod 24 is driven to rotate under the action of the motor 23. When the threaded rod 24 rotates, it will drive the connecting plate 22 on the connecting block 25 to move left and right. When the connecting plate 22 moves, it drives the pressure block 27 and the hydraulic cylinder 26 to move respectively. When the hydraulic cylinder 26 moves to the corresponding position on the shell 7, the rivet 13 is grabbed by the hydraulic cylinder 26 and moved to the workpiece above the worktable 15. At this time, the start of the pressure block 27 drives the automatic clamping mechanism 28 to move down and press the rivet 13 on the workpiece.
