[0002] In the current machining field, riveting machines are a common type of riveting assembly equipment. With increasing demands, higher requirements are being placed on the performance of riveting machines. Numerical Control Riveting Machines (NC machines) are automated devices that use numerical control technology (NC) to control the riveting process. They are widely used in aerospace, automotive, electronics, and other high-precision assembly industries. Their main function is to rivet metal materials or other structural components with high precision control. Compared to traditional manual riveting, NC riveting machines offer higher efficiency, more precise operation, and more consistent riveting quality.

[0003] In existing technologies, after processing, the parts are often stuck in the mold, requiring workers to manually remove them, which is not only time-consuming and labor-intensive, but also poses certain safety hazards. Utility Model Content

[0012] The beneficial effects of this utility model are:

[0013] 1. By activating the second cylinder, the inclined platform at its output end can be moved. The inclined platform moves on the outside of the slide rail with the help of the slider at its bottom to ensure that its movement direction remains horizontal and forward and backward. When the inclined platform moves, the roller on the outside of its top also moves in the guide groove. The guide groove ensures that the movement direction of the roller does not deviate. When the inclined platform moves, it changes the height of the roller, thereby changing the height of the bottom plate above the roller and the connecting rod. When the height of the connecting rod also changes, the top plate at its top will also move together. The top plate is pushed upward from the mold, pushing out the riveted parts for easy picking by the workers.

[0014] 2. The rotating rod is driven to rotate by starting the motor. When the rotating rod rotates, the first sprocket, which is symmetrically arranged on its outer side, will also rotate. The chain on its outer side will drive the second sprocket at the other end of the chain to rotate. The rotation of the second sprocket will drive the threaded rod to rotate. The threaded connection will drive the threaded block on its outer side to move. When the threaded block moves, the fixing rod and the limiting block at its top will also move together. The limiting plate on the inner side of the limiting block will engage with the slot on the outer side of the mold to fix the mold. When the mold needs to be replaced, simply start the motor to drive the limiting block to move. It is convenient to replace and simple to operate. Attached Figure Description

[0021] Specifically, by activating the second cylinder 18, the inclined platform 23 at its output end can be moved. The inclined platform 23 moves on the outside of the slide rail 25 with the help of the slider 24 at its bottom to ensure that its movement direction remains horizontal and moves back and forth. When the inclined platform 23 moves, the roller 20 on the outside of its top also moves in the guide groove 22. The guide groove 22 ensures that the movement direction of the roller 20 will not deviate. When the inclined platform 23 moves, it changes the height of the roller 20, thereby changing the height of the bottom plate 21 above the roller 20 and the connecting rod 15. When the height of the connecting rod 15 also changes, the top plate 14 at its top will also move together.

[0022] Please refer to Figures 1-3 The top of the workbench 1 is symmetrically provided with several support rods 2, the top of the support rods 2 is provided with a top plate 3, the top of the top plate 3 is provided with a first cylinder 4, the output end of the first cylinder 4 is provided with a lower pressure plate 6, the top of the lower pressure plate 6 is symmetrically provided with several guide rods 5, and the other end of the guide rods 5 is slidably connected to the top plate 3.

One end of the threaded rod 31 is provided with a second sprocket 29. The outer side of the second sprocket 29 is meshed with a chain 30. The other end of the inner side of the chain 30 is meshed with a first sprocket 28. The first sprocket 28 is symmetrically provided with a rotating rod 27 on the outside. The rotating rod 27 is fixedly connected to the output end of the motor 26.

[0027] Specifically, the motor 26 drives the rotating rod 27 to rotate. When the rotating rod 27 rotates, the first sprocket 28 symmetrically arranged on its outer side will also rotate. Through the meshing connection of the chain 30 on its outer side, the second sprocket 29 at the other end of the chain 30 can be driven to rotate. The rotation of the second sprocket 29 drives the threaded rod 31 to rotate. Through the threaded connection, the threaded block 32 on its outer side can be moved. When the threaded block 32 moves, the fixing rod 34 and the limiting block 12 at its top will also move together.

[0028] Please refer to Figures 1-3 The inner side of the limiting block 12 is provided with a limiting plate 33, and the outer side of the mold 13 is provided with a slot 7 that is adapted to the limiting plate 33.

[0029] Specifically, the mold 13 is fixed by the interlocking of the limiting plate 33 on the inner side of the limiting block 12 and the slot 7 on the outer side of the mold 13. When the mold 13 needs to be replaced, simply start the motor 26 to move the limiting block 12. This makes replacement convenient and the operation simple.
