[0002] Riveter (also known as riveting machine, riveting machine, riveting machine, riveting machine, etc.) is a new type of riveting equipment developed according to cold rolling principle, which refers to the mechanical equipment that can rivet the product with rivet. The equipment is compact in structure and stable in performance. Riveting machine mainly relies on rotation and pressure to complete assembly, and is mainly used in riveting occasions requiring rivets (hollow rivets, hollow rivets, solid rivets, etc.). The traditional riveter controls the movement of the upper die for riveting through mechanical operation, which cannot effectively control the intensity of riveting, resulting in unstable riveting quality, and is prone to wear and tear after long working time. When not working, the motor keeps rotating, the noise is too loud, and the energy consumption is increased.

[0003] In the prior art, the patent with publication number CN218109249U discloses a continuous processing type riveter, which comprises a workbench, a mechanical box is fixed on the upper surface of the workbench, a riveter body is arranged on one side of the upper surface of the mechanical box, a rotating plate is arranged on the upper surface of the mechanical box, two positioning seats are arranged at the two ends of the upper surface of the rotating plate, a rotating drive structure is arranged in the mechanical box, and a hydraulic rod is fixed at each corner of the lower surface of the workbench. In the utility model, the workbench, the mechanical box, the riveter body and the rotating plate are arranged, two positioning seats are arranged on the rotating plate, when the riveter is used to rivet parts, the rotating drive structure in the mechanical box can drive the rotating plate to rotate by 180 degrees, so that the two positioning seats are alternately rotated to the lower side of the riveter body for riveting operation, thereby realizing continuous processing and improving processing efficiency. Manual handling of the workpiece is not required during processing, and the danger in the riveting process is reduced.

[0004] The patent with publication number CN217551062U discloses a numerical control automatic rivet placing machine, which comprises a workpiece placing rack, a vibrating type along-rail material arranging mechanism, a sensing material blocking mechanism, a multi-section type clamping anti-falling mechanism and a material conveying rack. The vibrating type along-rail material arranging mechanism is arranged above the workpiece placing rack, and the sensing material blocking mechanism is arranged below one side of the vibrating type along-rail material arranging mechanism. The multi-section type clamping anti-falling mechanism is arranged on one side of the sensing material blocking mechanism. The material conveying rack is arranged below the workpiece placing rack. The vibrating type along-rail material arranging mechanism comprises a rotating assembly. The material arranging rack is in a directional lifting state inside the workpiece placing rack. A placing gap is left in the middle of the material arranging rack. In the lifting state, part of the material arranging rack will fall back into the workpiece placing rack because it is not aligned and clamped in the placing gap. Another part will be clamped in the placing gap, and the rivets on the upper part will continue to be used for subsequent rivet placing operation. After use, the above operation can be repeated.
