Bar locking machine

A bar locking machine comprises a first feeding module, a first transferring module, a platform module, a dismounting module, a locking module, a discharging module, a second feeding module and a second transferring module. The first feeding module receives a first rod piece from the outside, wherein the first rod piece is formed by connecting a dummy shaft and a residual material in a threaded mode. The first transferring module transfers the first rod piece to the platform module from the first feeding module. The platform module adjusts the first rod piece to be aligned with the machining center of the dismounting module and the machining center of the locking module. The dismounting module is used for dismounting the residual material of the first rod piece on the platform module and leaving the dummy shaft. The locking module screws the bar to the dummy shaft on the platform module to form a second bar. And the discharging module outputs the second rod piece. The second feeding module receives the bars f
