In the Y-axis module 3 , the Z-axis module 5 is slidably carried by the Y-axis sliding assembly 33 , and the Z-axis module 5 is driven to move along the Y-axis direction by the Y-axis driving mechanism 32 .

[0075] In some embodiments of the Z-axis module 5, such as Figure 5 As shown, the Z-axis module 5 includes a lifting bracket 51, a lifting drive mechanism 52 and two groups of Z-axis sliding components 53. The lifting bracket 51 is arranged on the Y-axis module 3, specifically, on the two groups of Y-axis sliding components 33. The two groups of Z-axis sliding components 53 are arranged side by side on the lifting bracket 51 along the Z-axis direction. The lifting drive mechanism 52 is arranged on the lifting bracket 51, and the lifting drive mechanism 52 is connected to the plate jig 9 to drive the plate jig 9 to perform lifting movement.

[0076] By setting up the Z-axis module 5 and taking the lifting bracket 51 as the basic installation structure, the lifting drive mechanism 52 drives the plate fixture 9 to move along the Z-axis direction, that is, drives the plate fixture 9 to perform lifting motion.

[0077] The lifting bracket 51 is a frame structure connected by rods or plates, and the lifting drive mechanism 52 is disposed in the lifting bracket 51 .

[0078] Specifically, the lifting drive mechanism 52 includes a lifting motor, a belt transmission group, a lifting nut, a lifting screw and a lifting drive block. The lifting screw is vertically arranged in the lifting bracket 51, and the lifting screw is rotatably arranged in the lifting bracket 51.

[0079] In some embodiments of the upper die device 6, such as Figure 2 shown, the upper die device 6 includes a riveting driving member 61 and an upper die 62. The upper die 62 is connected to the riveting driving member 61.

[0080] In some embodiments of the feeding device 7, such as Figure 6 , Figure 7 shown, the feeding device 7 includes a first mounting block 71, a feeder 72, a supporting mechanism 73, and a receiving driving mechanism 74.

[0081] Specifically, the feeder 72 is disposed on the first mounting block 71. The feeder 72 is connected to an external feeding device, such as a vibrating bowl. The vibrating bowl feeds the rivets into the feeder 72, and the feeder 72 has a discharge port. The supporting mechanism 73 is slidably disposed on the first mounting block 71. The moving path of the supporting mechanism 73 passes below the discharge port. The supporting mechanism 73 is provided with a supporting hole for positioning and supporting the riveting parts. When the supporting mechanism 73 slides or stops below the discharge port, specifically, the supporting hole is aligned with the discharge port. In this way, the rivets in the feeder 72 will fall into the supporting hole. The movement of the supporting mechanism 73 is executed by the receiving driving mechanism 74. The receiving driving mechanism 74 is connected to the supporting mechanism 73. The receiving driving mechanism 74 can drive the supporting hole of the supporting mechanism 73 to move to the discharge port, and the lower supporting hole is aligned with the discharge port.

[0082] In this embodiment, the receiving driving mechanism 74 drives the supporting mechanism 73 to move, so that the supporting mechanism 73 moves to the discharge port, specifically, the supporting hole is aligned with the discharge port. The feeder 72 is connected to an external feeding device to receive the rivets. The rivets fall from the discharge port, pass through the first mounting block 71, and fall into the supporting hole on the supporting mechanism 73. After that, the receiving driving mechanism 74 drives the supporting mechanism 73 to reset, thus completing the riveting feeding. The supporting mechanism 73 is a rivet supporting and positioning structure for the riveting mechanism during riveting. After riveting, the receiving driving mechanism 74 works again to perform a new round of riveting feeding. By driving the supporting hole to be aligned with the discharge port, and using the discharge port of the feeder 72 to feed the rivets into the supporting mechanism 73. After the supporting mechanism 73 receives the rivets, part of the rivets extends into the supporting hole, and the supporting hole supports and positions the rivets, so as to realize the feeding of the rivets. The riveting feeding mechanism of this embodiment can accurately position the rivets and improve the accuracy of subsequent riveting work.

[0083] For the supporting hole, it is allowed that the rivets pass through the supporting hole during stamping. The supporting hole is a variable supporting hole, and the variable supporting hole is a structure with variable dimensions.

[0084] In some embodiments of the supporting mechanism 73, an elastic limiting mechanism is provided in the supporting hole. For example, at least one spring plate is provided at a certain height in the supporting hole. When the rivet falls into the supporting hole, the spring plate supports the rivet. When the rivet is pressed, the spring plate undergoes elastic deformation to allow it to pass through.

[0085] In some embodiments of the supporting mechanism 73, such as Figure 8 As shown, the supporting mechanism 73 includes a supporting body 731 and two rotating members 732. The supporting body 731 is slidably connected to the first mounting block 71. The two rotating members 732 are rotatably arranged on the supporting body 731. The two rotating members 732 are arranged side by side, and the two rotating members 732 are elastically reset to the middle position. A supporting groove is provided on one side of the rotating member 732 close to the other rotating member 732, and the two supporting grooves are surrounded to form a supporting hole. The material receiving driving mechanism 74 is connected to the supporting body 731. The two rotating members 732 are arranged side by side, and the rotating member 732 is provided with a supporting groove at a position close to the other rotating member 732. The two supporting grooves are arranged relative to each other, so that the two supporting grooves form a supporting hole. When the rivet falling into the supporting hole is punched, the rotating member 732 rotates to avoid, and the through size of the supporting hole increases. After the punching is completed, the rotating member 732 is reset and rotated, thereby returning to the side-by-side state.

[0086] Furthermore, if Figure 8 As shown, in order to realize the elastic reset of the rotating member 732 to the middle position, the supporting mechanism 73 also includes two rotating shafts 733 and two reset springs 734. The two rotating shafts 733 are arranged side by side on the supporting body 731. The two rotating members 732 are rotatably arranged on the two rotating shafts 733. The two reset springs 734 are respectively sleeved on the two rotating shafts 733, and the two reset springs 734 are also respectively connected to the two rotating members 732, and the reset springs 734 drive the rotating member 732 to reset and rotate to the middle position. The two return springs 734 exert elastic force on the rotating member 732, so that the two rotating members 732 are continuously subjected to elastic force to rotate toward the middle position. When the rotating member 732 is subjected to external force, especially when the bearing groove is compressed, or when the rivet falling into the bearing hole is punched, under the action of manual external force, the rotating member 732 pushes the return spring 734, and the rotation avoidance occurs, and the through size of the bearing hole increases. When the external force retreats, disappears, or after the punching is completed, the return spring 734 pushes the rotating member 732 to perform a return rotation, so that the two rotating members 732 are restored to a state where they can support the rivet. In addition, the return spring 734 can be a torsion spring.

[0087] In some embodiments of the material receiving driving mechanism 74, the material receiving driving mechanism 74 includes a cylinder and a push rod, wherein the cylinder is connected to the first mounting block 71, and the cylinder drives the push rod to perform telescopic movement. The push rod is connected to the second mounting block.

[0088] In some embodiments of the first mounting block 71, in order for the feeder 72 to feed downward, a blanking hole is provided at one side edge of the first mounting block 71. The feeder 72 is disposed on the top of the first mounting block 71 and at the blanking hole, and the discharge port of the feeder 72 faces the blanking hole.

[0089] In some embodiments of the feeding mechanism, the feeding device 7 further includes a feeding mechanism, as Figure 6 shown, the feeding mechanism includes a mounting frame 75 and a feeding driving mechanism 76. The feeding driving mechanism 76 is disposed on the mounting frame 75, and the feeding driving mechanism 76 is connected to the first mounting block 71 to drive the first mounting block 71 to move.

[0090] Specifically, the feeding driving mechanism 76 includes a feeding motor, a feeding lead screw, a second guide rail, and a second slider. The feeding lead screw is rotatably disposed on the mounting frame 75. The feeding motor and the second guide rail are disposed on the mounting frame 75. The feeding motor is connected to the feeding lead screw. The second slider is slidably disposed on the second guide rail. The second slider is in threaded engagement with the feeding lead screw. The second slider is also connected to the first mounting block 71 to drive. The feeding motor drives the first mounting block 71 to move through the feeding lead screw and the second slider, drives the rivet to find the processing position, and feeds the rivet from the supporting mechanism 73.
