The utility model provides a quartz tube expanding production device. The quartz tube expanding production device comprises an outer melting unit, an inner melting unit and a connecting rod, wherein the outer melting unit is used for melting the outer side of a quartz tube to expand the tube diameter; the inner melting unit is used for melting the inner side of the quartz tube and assisting the outer melting unit in expanding the tube diameter; and the connecting rod is used for connecting the internal and external melting units to ensure that the internal and external melting units move synchronously. By means of the device, large-caliber thick-wall quartz tubes of various specifications can be expanded flexibly, the defects of inner wall scratches, inner repair marks and the like of existing products can be overcome, the quality of expanded tubes is improved, and the follow-up repair machining cost is saved. 本实用新型提供了一种石英管扩制的生产装置，包括：外熔融单元、内熔融单元和连接杆；其中，所述外熔融单元用于熔融石英管外侧进行管径扩制；所述内熔融单元用于熔融所述石英管内侧，辅助所述外熔融单元进行管径扩制
