Then, after the guide plate 24 is rotated to a suitable angle, the rotating nut 27 can be tightened, so that the movable plate 23 can be fixed and the guide plate 24 can be tilted. Therefore, when the two sets of guide plates 24 are used to guide the material, the material is located at the center displacement of the traction belt 13, which facilitates stable feeding.

[0022] Embodiment 3: On the basis of Embodiment 2, a turntable 9 is provided for facilitating the automatic displacement of the gear plate. The surface of the turntable 9 is provided with mounting holes 36. There are multiple groups of mounting holes 36, and the multiple groups of mounting holes 36 are regularly arranged in a circle around the limiting hole 10. The placing seat 37 is fixed in the mounting hole 36 by screwing with bolts. The surface of the turntable 9 is provided with threaded holes 25. A positioning screw 26 is screwed in the threaded hole 25. A rotating nut 27 is arranged on the surface of the positioning screw 26. A universal wheel 28 is arranged at the end face of the positioning screw 26. There are multiple groups of threaded holes 25, and the multiple groups of threaded holes 25 are equidistantly arranged in a circle around the limiting hole 10; During use, the turntable 9 can be driven to rotate by starting the driving motor 7, so that the multiple groups of placing seats 37 can be rotated, and then it is convenient to automatically displace the placing seat 37 directly below the riveting device 4, the needle feeding mechanism 5 and the gear plate assembly mechanism 6, so as to facilitate the automatic riveting of the gear plate. The surface of the turntable 9 is provided with multiple groups of mounting holes 36, so that the number of placing seats 37 can be adjusted to facilitate increasing the number of riveted gear plates.

[0023] A support plate 8 is provided for facilitating the installation and disassembly of the turntable 9. The surface of the turntable 9 is provided with threaded holes 25. A positioning screw 26 is screwed in the threaded hole 25. A rotating nut 27 is arranged on the surface of the positioning screw 26. A universal wheel 28 is arranged at the end face of the positioning screw 26. There are multiple groups of threaded holes 25, and the multiple groups of threaded holes 25 are equidistantly arranged in a circle around the limiting hole 10. A limiting port 29 is opened on the side of the limiting hole 10. The support plate 8 is integrally in a ring plate structure. A baffle 30 is arranged on the side of the support plate 8. The support plate 8 is fixedly connected to the transmission end of the driving motor 7. The baffle 30 is in a square plate structure. A hole is opened on the surface of the baffle 30, and a damping bearing 31 is arranged in the hole. The inner ring surface of the damping bearing 31 is fixedly connected with a limiting rod 32. A limiting block 33 is arranged at one end of the limiting rod 32. The limiting block 33 is in a square plate structure. A bottom plate 34 is arranged at the bottom of the turntable 9. A limiting groove 35 is opened on the side of the bottom plate 34. The limiting block 33 is inserted into the limiting groove 35, and the length and width of the limiting block 33 are smaller than the length and width of the baffle 30; When the turntable 9 needs to be disassembled during use, first, the limiting rod 32 can be rotated in cooperation with the damping bearing 31, so that the limiting block 33 can be disengaged from the limiting groove 35 and lose the limiting effect on the bottom plate 34. Then, the turntable 9 can be directly pulled out from the support plate 8. When installing, first, the baffle 30 is snapped into the limiting port 29, and then the limiting block 33 can be rotated to insert the limiting block 33 into the limiting groove 35. Thus, the turntable 9 can be driven to rotate by starting the driving motor 7. The baffle 30 is snapped into the limiting port 29 to prevent the turntable 9 from slipping relative to the support plate 8. When rotating the turntable 9, the cooperation of the positioning screw 26 and the universal wheel 28 can be used to support the bottom of the turntable 9, reducing the pressure on the driving motor 7 and facilitating the driving of the turntable 9. Then, the positioning screw 26 can be rotated by rotating the nut 27, so that the positioning screw 26 can be screwed out of the threaded hole 25, and thus the positioning screw 26 can be separated from the turntable 9 more conveniently.

[0024] During actual use, first, the gear plate vibratory bowl 2 cooperates with the feeding plate 11 to feed the gear plate. The surface of the workbench 3 is provided with a needle feeding mechanism 5, a gear plate assembling mechanism 6, a riveting device 4 and a discharging mechanism. Through the needle feeding mechanism 5, the gear plate needles are first loaded onto the placing seat 37, and then the driving motor 7 drives the turntable 9 to rotate. The gear plate assembling mechanism 6 loads the stepping motor gear plate onto the turntable 9. Then the turntable 9 rotates into the riveting device 4 to rivet the gear plate needles and the gear plate, so that the gear plate can be quickly riveted. After riveting, the hydraulic electric push rod 15 is used to automatically push and discharge the parts. In order to facilitate the feeding of gear plates with different widths, the moving plate 23 can be sleeved on the positioning bolt 22, and then the positioning bolt 22 is screwed into the threaded groove 20. Then the guiding plate 24 can be rotated. The opening of the arc-shaped groove 21 can prevent one end of the guiding plate 24 from colliding with the side surface of the feeding plate 11 when the guiding plate 24 is rotated. Then, after the guiding plate 24 is rotated to a suitable angle, the rotating nut 27 can be tightened, so that the moving plate 23 can be fixed and the guiding plate 24 can be tilted. Thus, when the two guiding plates 24 are used to guide the material, the material is located at the central displacement of the traction belt 13, which is convenient for stable feeding. The limiting rod 32 can be rotated in cooperation with the damping bearing 31, so that the limiting block 33 can be disengaged from the limiting groove 35 and lose the limiting effect on the bottom plate 34. Then, the turntable 9 can be directly pulled out from the support plate 8. When installing, first, the baffle 30 is snapped into the limiting port 29, and then the limiting block 33 can be rotated to insert the limiting block 33 into the limiting groove 35. Thus, the turntable 9 can be driven to rotate by starting the driving motor 7. The baffle 30 is snapped into the limiting port 29 to prevent the turntable 9 from slipping relative to the support plate 8.
