Description
Technical Field
The utility model relates to the technical field of blind rivet guns, in particular to a rivet feeding device of a blind rivet gun.
Background
Before a blind rivet gun can rivet a workpiece, a blind rivet needs to be conveyed to a gun nozzle of the blind rivet gun, and the action is called rivet feeding. In the prior art, a Chinese patent document with the application number of 202021120863.X discloses a blind rivet gun nozzle device, which comprises a gun body, an automatic rivet feeding assembly and a driving assembly, wherein a fixed block is arranged on the gun body and is connected to one side of the gun body along the axis direction of the gun body, the driving assembly is connected with the fixed block, and the automatic rivet feeding assembly is connected with the driving end of the driving assembly; the automatic nail feeding assembly comprises a rocker arm seat connected with one end, far away from the sliding block, of the connecting plate, an upper rocker arm and a lower rocker arm which are respectively arranged on the rocker arm seat in a rotating mode, an upper nail clamping head arranged on one side of the upper rocker arm, a lower nail clamping head arranged on one side of the lower rocker arm and a top rod arranged at one end, close to the gun nozzle, of the sliding rail. The automatic feeding pin assembly of the patent document has poor working stability, unstable pin feeding and easy pin falling.
The Chinese patent document with the application number of 202222351803.4 discloses a nail feeding device for loose core rivet pulling, which comprises a mounting plate and a bearing base arranged on the mounting plate, wherein a nail feeding pipeline is arranged on one side of the bearing base, a nail feeding assembly is arranged below the mounting plate, the nail feeding assembly is connected with the mounting plate through a lifting control assembly, and the nail feeding assembly comprises a connecting base and a transverse movement nail grabbing assembly arranged on the connecting base; the transverse movement nail grabbing assembly is provided with a pneumatic handle controlled by a horizontal cylinder assembly. According to the patent document, the rivet sliding out from the bottom of the rivet outlet pipeline is clamped by the pneumatic handle, and the rivet falls to make translational transfer action, so that rivet feeding operation on the rivet in the rivet outlet pipeline is realized. Because the rivet output by the rivet outlet pipeline is directly clamped by the pneumatic gripper, the rivet receiving stability is poor, and the positions of the rivet clamped by the pneumatic gripper are not uniform. In addition, the rivet is clamped by the pneumatic handle after falling to a preset position by gravity and then is transferred out, so that the rivet is limited to only conveying the rivet from top to bottom, not horizontally conveying the rivet, and the use is limited.
Thus, the drawbacks are quite apparent and there is a need to provide a solution.
