[0002] The double-column vertical lathe is a process testing instrument used in the field of mining engineering technology. It can be used for rough turning or fine turning of the outer circle, inner hole and end face of the workpiece. The weight of the beam structure is borne by the two lead screws located on the left and right columns. The movement of the beam structure is driven by the synchronous operation of the two lead screws. The power of the two lead screws is provided by the same motor after a first-stage worm and worm gear reduction.

[0003] The current double-column vertical lathes are prone to deviations during the assembly process, which affects the level of the beam structure and affects the processing of parts. When an error occurs in the lifting beam structure, the staff is required to use tools to fine-tune the beam structure. The double-column vertical lathe is large in size, and the staff's use of tools to adjust the beam structure is likely to reduce the processing efficiency of the double-column vertical lathe.
