Semi-automatic riveting machine

The invention discloses a semi-automatic riveting machine. The semi-automatic riveting machine comprises a vibration disc, a feeding mechanism, a rack, a movable clamp, a first air cylinder, a riveting mechanism and a riveting base, wherein the feeding mechanism is connected to a discharging port of the vibration disc and is connected to the rack through a hose; the movable clamp is arranged belowthe hose; the first air cylinder is used for driving the movable clamp to move horizontally; the riveting base is arranged on the rack; the riveting mechanism is arranged above the riveting base; anda rivet is inserted into an aluminum sheet through the riveting mechanism and the riveting base. The movable clamp is arranged to temporarily clamp the rivet, the manual handheld clamping is replaced, and the riveting safety is greatly improved. Meanwhile, a negative-pressure air hole is formed in the end of a riveting head, and the rivet is adsorbed through negative-pressure suction force so asto ensure that the position
