The invention discloses a slideway type automatic feeding mechanism of a spherical roller grinding machine. A vibrating disk mechanism comprises a vibrating disk and a vibrating disk material blocking piece installed at a discharge port of the vibrating disk. An industrial camera is arranged in the mode that the industrial camera right faces the discharge port of the vibrating disk through an industrial camera fixing plate. A stepping motor fixing plate is arranged on the industrial camera fixing plate. A stepping motor and a material shifting blade are arranged above the discharge port of the vibrating disk through the stepping motor fixing plate. A controller is connected with the stepping motor and the industrial camera. A conveying mechanism comprises a first spiral material distribution slideway, a second spiral material distribution slideway, a first intermediate straight slideway and a second intermediate straight slideway, wherein the first spiral material distribution slideway and the second spiral material distribution slideway are connected to the two sides of the discharge port of the vibrating disk, the first spiral material distribution slideway and a first spiral steering slideway are connected through the first intermediate straight slideway, and the second spiral material distribution slideway and a second spiral steering slideway are connected through the second intermediate straight slideway. According to the slideway type automatic feeding mechanism of the spherical roller grinding machine, the end faces of rollers can be recognized automatically, the end faces of all the rollers are adjusted to face the same direction, and then the rollers are conveyed to the spherical roller grinding machine; in addition, the rollers can be conveyed to two spherical roller grinding machines at the same time.
