The invention discloses a multi-output riveting machine control system, The multi-output riveting machine control system comprises a PLC controller, a bearer and an iron tool box, a control output terminal of the PLC controller is electrically connected with electric control terminals of a moving mechanism, a feeding conveyer belt, a loading mechanism, a riveting mechanism, an unloading mechanismand a discharging conveyer belt, the upper part of the bearer is fixedly connected with a riveting bench, the inner bottom of the riveting bench is provided with a moving hole, and the inner side of the riveting bench is provided with a distance measuring sensor. By designing the riveting bench, the position of the iron tool box can be detected during the riveting process, accurate positioning isfacilitated, and the case that mis-riveting occurs, and the equipment and product are damaged is avoided; the moving mechanism is used for moving the iron tool box to move and rotate on the riveting bench along the moving hole in the horizontal direction, and accurate positioning is facilitated; and at the same time, the multi-output riveting machine control system can be applied to a plurality ofriveting mechanisms for carrying out riveting, and the production efficiency is high.
