Gantry type preassembling pre-adjusting station with on-line measuring function

The invention relates to the technical field of digital manufacturing, in particular to a gantry type preassembling and presetting station. According to the technical scheme, a gantry type preassembling and presetting station with the online measuring function is characterized in that a workbench is installed on a lathe bed and can move front and back along the lathe bed; a workpiece is installed on the workbench through a tool and is driven by the workbench to enter and exit from the gantry type preassembling and presetting station. The lifting door is installed at one end of the gantry type preassembling and presetting station, and after a workpiece enters the gantry type preassembling and presetting station, the lifting door is closed; and the automatic measuring device is arranged on the three-axis linkage mechanism. According to the invention, loading, unloading, presetting, online detection, high-precision positioning and chip removal can be carried out on the to-be-processed part, small-batch and multi
