[0021] The following is combined with Figure 1-4 This application is described in further detail.

[0022] The present application embodiment discloses a feeding device for a riveting machine, referring to Figure 1-Figure 4 , including a frame 1, a support column 8 is fixedly installed on the upper end of the frame 1, a loading box 9 is fixedly installed on the top of the support column 8, a charging hopper 10 and a driving motor 12 are installed on the upper end of the loading box 9, the bottom of the charging hopper 10 passes through the loading box 9 and is fixedly connected with a feeding pipe 11, the output end of the driving motor 12 passes through the loading box 9 and is connected with a driving gear 13, the outer side of the driving gear 13 is meshed with a synchronous rack belt 14, the other end of the synchronous rack belt 14 is meshed with a driven gear 15 on the inner side, the bottom of the driven gear 15 is rotatably connected to the bottom of the inner surface of the loading box 9, and the synchronous rack belt 14 is evenly and fixedly installed with a plurality of guide plates 16, the driving motor 12 drives the driving gear 13 inside the loading box 9 to rotate, and cooperates with the driven gear 15 to drive the synchronous rack belt 14 to move under the meshing action, at this time The rivet falls vertically along the feed pipe 11 to the inner side of the guide plate 16 on the outer side of the synchronous rack belt 14, and a discharge pipe 19 is fixedly installed on the right bottom of the loading box 9. A limit plate 17 is fixedly installed inside the loading box 9. The limit plate 17 is installed to limit the port of the guide plate 16 during the activity to prevent the rivet on the inner side of the guide plate 16 from tipping over, thereby ensuring the stability of the rivet material during transportation. A notch 18 is reserved at each end of the limit plate 17, and the two notches 18 correspond to the feed pipe 11 and the discharge pipe 19 respectively. When the synchronous rack belt 14 moves to the set position, the rivet is at the preset notch 18 at one end of the discharge pipe 19, and then falls along the discharge pipe 19 to the inside of the riveting seat 7 to complete the loading operation, which greatly reduces the labor intensity of the staff, realizes automatic loading, and avoids injuries caused by manual loading operation errors.

[0023] Reference Figure 1-Figure 4A riveting machine body 2 is fixedly installed on the upper end of the frame 1, and a hydraulic cylinder 3 is installed on the top of the riveting machine body 2. The bottom of the hydraulic cylinder 3 penetrates the riveting machine body 2 and is connected to a punch 4. The punch 4 is driven down by the hydraulic cylinder 3 to perform riveting operations on the rivets inside the riveting seat 7. A fixed seat 5 is fixedly installed in the middle of the upper end of the frame 1. The interior of the fixed seat 5 is arranged as a hollow structure. A rotating workbench 6 is arranged on the upper end of the fixed seat 5. A plurality of riveting seats 7 are evenly fixedly installed on the top of the rotating workbench 6. The upper end of the riveting seat 7 corresponds to the bottom of the feeding tube 19. When the riveting seat 7 completes the feeding at the bottom of the feeding box 9, it rotates to make the bottom of the punch 4 perform riveting operations. At this time, another riveting seat 7 corresponds to the bottom of the feeding tube 19 for feeding. In this way, under the uninterrupted feeding processing operation, the processing effect of the device is greatly improved and the practicality is enhanced.

[0024] Reference Figure 4 A rotating rod is fixedly installed at the bottom of the rotating workbench 6, and the rotating workbench 6 passes through the fixed seat 5 through the rotating rod and is connected to the transmission worm gear 20. A servo motor 21 is installed on the side of the fixed seat 5. The output end of the servo motor 21 passes through the fixed seat 5 and is connected to the worm 22. The other end of the worm 22 is rotatably connected to the inner side of the fixed seat 5, and the outer side of the worm 22 is meshed with the side of the transmission worm gear 20. The servo motor 21 drives the worm 22 to rotate on the inner side of the fixed seat 5, so that the rotating workbench 6 rotates at the upper end of the fixed seat 5 through the meshing action of the transmission worm gear 20 and the worm 22 at the bottom thereof.

[0025] The implementation principle of a feeding device for a riveting machine in an embodiment of the present application is as follows: when using the device, first fill a proper amount of rivets into the interior of the loading hopper 10, then start the drive motor 12 to drive the driving gear 13 inside the loading box 9 to rotate, and cooperate with the driven gear 15 to drive the synchronous rack belt 14 to move under the meshing action. At this time, the rivets inside the loading hopper 10 fall vertically along the feed pipe 11 to the inside of the guide plate 16 outside the synchronous rack belt 14, and are transported as the synchronous rack belt 14 rotates. At the same time, the limit plate 17 inside the loading box 9 limits the guide plate 16 to prevent the rivets from tipping over during the activity. When the synchronous rack belt 14 moves to the preset notch 18 at one end of the discharge pipe 19, the rivets will fall through the discharge pipe 19 to the inside of the riveting seat 7 due to the lack of the blocking effect of the limit plate 17, thereby completing the automated feeding operation.
