The invention provides a use method of a gantry
production line for improving material carrying precision, and belongs to the technical field of
machining, and the use method comprises the following steps: S1, a loading and unloading
station hoists a workpiece, clamps the workpiece, binds the workpiece with a tray, and transfers the workpiece to a truss area; s2, the truss is transferred to a pre-adjusting
station, blank data are scanned and compared, and a benchmark is pre-adjusted; s3, the central
control system dispatches the truss to precisely convey the tray to a
machining center, and the repeated positioning precision is smaller than or equal to 0.03 mm through multi-stage positioning; s4, after four-axis rough
machining, the truss is transferred to a fifth axis for high-precision machining; s5, the central
control system performs whole-process management and control; and S6, after machining is completed, treating through a
cleaning station, and returning to a loading and unloading
station for disassembly. Through high-precision positioning, intelligent presetting and full-process management and control, the machining precision and efficiency can be improved, so that multi-variety flexible production can be achieved, and the requirements of high-end manufacturing for high efficiency, precision and flexibility can be met.
