[0013] First, the crossbeam lifting structure of a single-column vertical lathe of the present utility model is provided to facilitate the rotation and parking of the control box. The staff pulls the control box to move through the handles on both sides of the control box. The force-bearing movement of the control box drives the rotation of the strut rod. The bottom of the strut rod is fixedly connected to the driving gear. The driving gear is meshed with the driven gear. The rotation of the driving gear drives the rotation of the driven gear. When the control box rotates to a certain position and stops, the positioning ball pops up and engages in the groove at the bottom of the driven gear, and the driven gear and the driving gear stop rotating, thereby reducing the deviation amplitude of the control box.
