[0001] The invention belongs to the technical field of nut riveting, and in particular relates to a riveting device for preventing a riveted nut from tilting. Background Art

[0002] When the common nut press riveting machines on the market are working, it is necessary to first place the rivet nut in the hollow mold column, then place the sheet metal on the rivet nut, and align the rivet hole of the sheet metal with the rivet nut, and then press the sheet metal down through the nut press to fix the rivet nut in the rivet hole of the sheet metal. However, during the entire riveting process, workers are required to manually stabilize the sheet metal. Therefore, during riveting, workers are prone to hand shaking, causing the sheet metal to shake, which in turn causes the rivet nut to tilt during riveting.

[0036] A method for using a riveting device to prevent the riveting nut from tilting:

[0037] Step 1: Place the rivet nut on the top of the hollow mold column 15, then place the sheet metal on the top of the pressure plate 45, and align the rivet hole of the sheet metal with the rivet nut. The worker steps on the first foot switch 21 to control the first cylinder 23 through the main controller 2 to start working, and the first cylinder 23 drives the support frame 4 to move upward, and then drives the magnetic block 42 to move upward into the avoidance groove of the tray 44 through the connecting block 41, so that the magnetic block 42 is close to the sheet metal. The magnetic attraction of the magnetic block 42 on the sheet metal ensures that the sheet metal can be stably placed on the top of the pressure plate 45, thereby ensuring that when the sheet metal and the rivet nut are riveted later, the rivet nut will not be tilted during riveting due to the shaking of the sheet metal, and the worker does not need to hold it by hand during the riveting process, thereby improving safety in use.

[0038] Step 2: The worker steps on the second foot switch 22 to control the second cylinder 24 through the main controller 2 to start working. The second cylinder 24 drives the rivet head 25 and the stabilizing ring 32 to move downward. When the stabilizing ring 32 moves downward and contacts the sheet metal, its top will be pressed and fixed, so as to further improve the riveting stability of the sheet metal. When the second cylinder 24 continues to work, it will drive the rivet head 25 to press the sheet metal down so that it can be riveted with the rivet nut.

[0039] Step three: During the riveting process, the pressure plate 45 will move downward and squeeze the second spring 46 due to the downward pressure from the sheet metal. When the riveting is completed, the first cylinder 23 drives the magnetic block 42 to move downward and reset, and the second cylinder 24 drives the rivet head 25 and the stabilizing ring 32 to move upward and reset. At this time, the second spring 46 uses its own resilience to drive the riveted sheet metal to move upward through the pressure plate 45, so that the riveted nut and the hollow mold column 15 become loose, so that the riveted sheet metal can be easily removed.

[0040] Step 4: The third spring 234 uses its own elastic force to drive the round head pin 233 to be inserted into the locking hole of the guide column 3, so as to fix the guide column 3 on the outside of the rivet head 25. The support foot 43 is stably fixed in the socket of the second bracket block 13 through the magnetic attraction of the magnetic block 235 and the iron block 236. At the same time, the first cylinder 23 is fixed to the top of the first bracket block 12 by the bolt 232. When the stabilizing assembly 300, the anti-tilt assembly 400 and the first cylinder 23 fail and need to be repaired, the stabilizing ring 32 is pulled downward to make it staggered with the rivet head 25, and then the two groups of guide columns 3 can be slid forward to separate from the rivet head 25. In this way, the stabilizing component 300 can be disassembled, and the tray 44 can be pulled upward to drive the supporting foot 43 to separate from the second supporting block 13, and then the first cylinder 23 drives the magnetic block 42 to move upward and staggered with the hollow mold column 15 through the supporting frame 4 and the connecting block 41. At this time, the bolt 232 is unscrewed, and the first cylinder 23 can be disassembled together with the anti-tilt component 400, which can achieve the effect of rapid disassembly and maintenance. After the stabilizing component 300, the anti-tilt component 400 and the first cylinder 23 are disassembled, the device will be changed to a traditional nut riveting machine to ensure that it can continue to perform riveting work, thereby ensuring production efficiency.
