An automatic rivet conveying mechanism for large-diameter steel rivets comprises a rivet feeding movable spring clamp, a rivet feeding fixed spring clamp, a mechanism installation guide base, a guidemechanism spring clamp, a guide mechanism spring clamp base and a limiting stop block. The rivet feeding movable spring clamp and the rivet feeding fixed spring clamp are combined to form a spring clamp and are connected through extension springs. The two ends of each extension spring are fixed to the rivet feeding movable spring clamp and the rivet feeding fixed spring clamp through spring fixingpins correspondingly. The rivets are installed in the spring clamp, and stretching rods of the rivets fall on the limiting stop block so as to limit the spring clamp. A guide groove structure is formed in the mechanism installation guide base, and the rivet feeding fixed spring clamp is installed in the guide groove structure of the mechanism installation guide base and moves along the guide groove.
Description
technical field [0001] The invention belongs to the field of rivets, in particular to an automatic rivet feeding mechanism for large-diameter steel rivets. Background technique [0002] The mandrel assembly is mainly riveted by the rudder core and the rudder shaft. The assembly process includes drilling, reaming, scribing, nailing, riveting, milling and other processes. The riveting uses large-diameter stainless steel rivets. The rivets and The fit tolerance of the nail hole is At present, the workshop adopts manual installation of rivets, and some rivets are inserted by tapping, which is labor-intensive, low in efficiency, and easy to damage products. With the improvement of quality requirements and batch production of models, this assembly method can no longer meet the needs of production. [0003] The Chinese patent document with the publication number CN103706752A discloses an automatic nail selection and nail feeding system used with a multifunctional automatic drill...
