A linear gear shaft and gear plate automatic combination riveting machine of the present invention includes a machine case, a machine table, a man-machine operation interface, a column gear feeding mechanism, a column gear stripping cylinder, a riveting combination mechanism, a piece gear feeding mechanism, and a finished product unloading mechanism. Feeding mechanism, pressure switch and pressure sensing display. The invention can realize a series of operations such as automatic feeding, automatic changing of the conveying direction of the workpiece, automatic positioning, automatic precise riveting, automatic material suction and unloading for the column gear and the plate gear. It not only has firm riveting, but also has high riveting efficiency. , high riveting precision and high production capacity, which also reduces the labor intensity and labor cost of workers, and ensures that the finished products riveted by it can reach a uniform standard. As a result, it has the problems of low riveting efficiency, poor riveting precision, inconsistent riveting pressure and difficulty in reaching uniform standards for riveted finished products.
