The invention relates to an automatic production device and a production method of a spiral lamp tube. The automatic production device comprises a machine frame, as well as a heating furnace, an inflated claw and a coil pipe mould which are mounted on the machine frame; a spiral groove is arranged on the outer surface of the coil pipe mould, and can rotate and lift relatively to the machine frame; and the inflated claw is connected with the machine frame through a transversal movement mechanism and a longitudinal movement mechanism. The automatic production device further comprises a control device; the control device is composed of a console, a control circuit and a drive device; the console is connected with the drive device through the control circuit; the drive device controls the action of the inflated claw and the coil pipe mould to be mutually connected during the manufacturing process of the lamp tube. The automatic production device can ensure that the production of the lamp tube realizes numerical control automation, so that the temperature, the speed, the position and other parameters during the production process achieve fine control, and an operator can be far away from the operating environment with high temperature.
