Semi-automatic double-track rivet feeding machine

The utility model relates to a semi-automatic double-track rivet feeding machine, and belongs to the field of mechanical production. A rivet inlet is formed in the upper end of a connection plate, and a rivet selection mechanism is connected with an inner hole of the connection plate through a rotation shaft in a screwed mode. A singular rivet track is fixedly connected with the connection plate, a rivet feeding cylinder is fixedly connected with the connection plate, and a rivet separation tension bolt is fixedly connected with the rivet feeding cylinder. A tension bolt locating seat is located at the joint of the singular rivet track and a double-track rivet feeding mechanism. The tension bolt locating seat is fixedly connected with the connection plate, the rivet separation tension bolt is in clearance fit with the tension bolt locating seat, and the double-track rivet feeding mechanism is fixedly connected with the connection plate. An outlet is formed in the outer side of the singular rivet track, a rivet return opening is formed in the upper end of the singular rivet track, and an outlet chamfer, an inner chamfer and a rivet outlet are formed in the inner side of the rivet selection mechanism. A first bayonet and a second bayonet are formed in the rivet separation tension bolt. The semi-automatic double-track rivet feeding machine is novel in structure and convenient to use, and double-rivet feeding is modified, so that rivet feeding efficiency is improved. Unqualified rivets can be taken out in time, and therefore the rivet feeding process can be smoothly conducted.
