Quartz rod manufacturing device and rod manufacturing method

The invention relates to the technical field of quartz rod manufacturing, and discloses a quartz rod manufacturing device and a rod manufacturing method. The quartz rod manufacturing device comprises a stretching assembly, a detection assembly and a gas correction assembly. The stretching assembly is used for stretching a quartz rod into a core rod which is equal to the quartz rod in size and small in diameter. The detection assembly is arranged below the stretching assembly, and the detection assembly is configured to be capable of detecting the deviation direction and distance of the axis of the core rod relative to the axis of the quartz rod; the gas correction assembly is arranged at the end, away from the stretching assembly, of the detection assembly, surrounds the core rod and is configured to drive the core rod to move to a preset position. The gas correction assembly surrounding the core rod is arranged at the end, away from the stretching assembly, of the detection assembly, gas is sprayed towards t
