[0020] To more clearly illustrate the technical solution of this utility model, the following description is made in conjunction with the accompanying drawings. Obviously, the drawings described below are only one embodiment of this utility model. For those skilled in the art, other embodiments can be obtained based on these drawings and embodiments without creative effort, and all of them fall within the protection scope of this utility model.

[0021] according to Figure 1-6 As shown, a sheet metal riveting device for sheet metal processing includes a frame 1. A support platform 2 is fixedly installed on the front side of the frame 1. A bearing platform 3 is rotatably installed on the support platform 2. Several sets of riveting seats 4 are arranged in a circumferential array on the bearing platform 3. A drive mechanism for driving the bearing platform 3 to rotate is installed at the bottom of the support platform 2. A feeding base plate 5 is provided on the moving path of the riveting seat 4. The feeding base plate 5 is movably installed on the frame 1. A guide frame 6 is fixedly installed on the top of the feeding base plate 5. A feeding rod 7 is movably installed on the guide frame 6. A storage rack 8 is provided at the end of the guide frame 6 away from the riveting seat 4. A discharge port 81 matching the guide frame 6 is opened on the storage rack 8.

[0022] In this embodiment, the driving mechanism includes a drive motor 9, which is fixedly mounted on the bottom of the support platform 2 via a motor bracket. The power output shaft of the drive motor 9 is connected to the rotating shaft of the bearing platform 3 via a coupling. Several sets of connecting screws 10 are welded to the top of the bearing platform 3 near the edge. The riveting seat 4 is installed on the connecting screws 10 via threaded engagement. Preferably, there are two sets of riveting seats 4. During riveting, the drive motor 9 drives the bearing platform 3 to rotate, causing the two sets of riveting seats 4 to move alternately in front of the operator, so that the operator can perform the riveting work on the plate. At the same time, the riveting seat 4 located on the rear side abuts against the end of the feeding base plate 5. The rivet nut is pushed onto the riveting seat 4 by the feeding rod 7 to achieve automatic feeding during the riveting process.

[0023] In this embodiment, a base frame 11 is fixedly installed at the bottom of the feeding base plate 5, a slider 12 is fixedly installed on the base frame 11, a guide rail 13 is slidably installed on the slider 12, the guide rail 13 is fixedly installed on the frame 1, and a first cylinder 14 is fixedly installed on the frame 1 via a bracket. The power output end of the first cylinder 14 is fixedly connected to the base frame 11. The first cylinder 14 drives the base frame 11 to rise or fall along the guide rail 13. When the base frame 11 falls to the bottom limit position, the top surface of the feeding base plate 5 is flush with the top surface of the riveting seat 4.

[0024] In this embodiment, a guide groove 61 is provided at one end of the guide frame 6 near the riveting seat 4. The guide frame 6 is fixedly installed on the top of the feeding base plate 5 by bolts. The feeding rod 7 is slidably installed on the side wall of the guide frame 6 away from the riveting seat 4. A second cylinder 15 is fixedly installed at the bottom of the feeding base plate 5. A push plate 16 is fixedly installed at the power output end of the second cylinder 15. The push plate 16 is fixedly installed at the end of the feeding rod 7 away from the riveting seat 4. The thickness of the guide frame 6 is equal to the thickness of a single rivet nut. The rivet nuts in the storage rack 8 can only fall into the guide groove 61 one by one. When the push rod of the second cylinder 15 retracts, it drives the feeding rod 7 to move, so that the feeding rod 7 pushes the rivet nuts in the guide groove 61 onto the riveting seat 4.

[0025] In this embodiment, the storage rack 8 is fixedly installed on the feeding base plate 5 by bolts. The bottom of the storage rack 8 has a groove 82, which is flush with the top surface of the guide rack 6. The discharge port 81 is located inside the guide groove 61. The front side wall of the storage rack 8 has an observation slot 83 corresponding to the discharge port 81. When the feeding rod 7 pushes the rivet nut in the guide groove 61 to the riveting seat 4, the feeding rod 7 blocks the discharge port 81 from falling down into the guide groove 61. After the feeding rod 7 resets, it moves away from the discharge port 81, and the rivet nut falls into the guide groove 61, thereby conveying the rivet nuts to the riveting seat 4 for riveting. The remaining amount of rivet nuts in the storage rack 8 can be observed through the observation slot 83, and the staff can replenish them in time when they are almost used up.

[0026] In this embodiment, a hydraulic cylinder 17 is fixedly installed at the top front end of the frame 1. A pressure head 18 is fixedly installed on the power output shaft of the hydraulic cylinder 17. A riveting head 19 is installed at the bottom of the pressure head 18 through a threaded connection. When the riveting seat 4 moves to the riveting position, the riveting head 19 is on the same axis as it. The hydraulic cylinder 17 drives the pressure head 18 to descend, so that the riveting head 19 rivets the rivet nut to the sheet metal part together.

[0027] In use, this invention first lowers the feeding base plate 5 via the first cylinder 14, making it flush with the top surface of the riveting seat 4 on the rear side. Then, the second cylinder 15 pushes the feeding rod 7 to push the rivet nut in the guide groove 61 onto the riveting seat 4. After that, the first cylinder 14 raises the feeding base plate 5, while the second cylinder 15 resets the feeding rod 7 to prepare for subsequent loading operations. After the feeding base plate 5 rises, the drive motor 9 rotates the support platform 3 180 degrees, causing the two sets of riveting seats to alternate positions. At this time, the riveting seat 4 with the rivet nut moves in front of the operator to facilitate the riveting of the sheet metal. Simultaneously, the first cylinder 14 lowers the feeding base plate 5 again to perform the above loading operation. Therefore, automatic loading is achieved during the riveting process, effectively improving operating efficiency and facilitating mass production of products.

[0028] The above embodiments are merely exemplary embodiments of this utility model and are not intended to limit this utility model. The scope of protection of this utility model is defined by the claims. Those skilled in the art can make various modifications or equivalent substitutions to this utility model within its substance and scope of protection, and such modifications or equivalent substitutions should also be considered to fall within the scope of protection of this utility model.
