When the riveting assembly 16 on the rotating seat 3 rotates to the bottom of the riveting head 15, the rotating motor 7 is turned off to make the rotating seat 3 stationary. At this time, the riveting head 15 moves down for riveting processing. After the riveting processing, the riveting head 15 moves up and the rotating motor 7 is started to drive the rotating seat 3 to continue rotating. Each time the rotating seat 3 rotates 120 degrees, different riveting heads 15 and riveting assemblies 16 are moved to the bottom of the riveting head 15 in turn.
