The invention relates to a double-worktable numerical-control machining center, in particular to a double-worktable exchanging mechanism of a machining center. The double-worktable exchanging mechanism of the machining center comprises a liftable base and two worktable support devices. The two worktable support devices are positioned on the upper side of the base; wireless positioning devices are further arranged on the exchanging mechanism and comprise wireless positioning switches and positioning screws, each wireless positioning switch is fixedly mounted on a side of the corresponding worktable support device, and the positioning screws are arranged on the base and are correspondingly positioned below the wireless positioning switches. The double-worktable exchanging mechanism has the advantages that shortcomings and worry due to mechanical positioning in the prior art can be overcome by wireless positioning mechanisms, the geometric precision of matching between the worktable support devices and the base can be guaranteed after worktables are exchanged, workpieces can be firmly clamped, and accordingly personal casualties or equipment damage due to separation of the two worktable support devices and the base when the two worktable support devices rotate in the air at high speeds can be prevented; the positioning speeds further can be increased, accordingly, the machining efficiency can be greatly improved, and the precision of components can be guaranteed.
