The invention provides a quartz tube expanding production device and method. The 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 so as 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 tube diameter expansion; the connecting rod is used for connecting the inner melting unit and the outer melting unit, and it is guaranteed that the inner melting unit and the outer melting unit move synchronously. By means of the device and method, large-diameter 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. 本发明提供了一种石英管扩制的生产装置及方法，其生产装置包括：外熔融单元、内熔融单元和连接杆；其中，外熔融单元用于熔融石英管外侧以进行管径扩制；内熔
