AUTOMATIC PALLETE CHANGER APPARATUS OF A MACHINING CENTER WITH ENHANCED CHANGING VELOCITY

摘要

The present invention provides automatic pallet changer to install the countertops in the upper pole laying on the bed top surface and bottom sides Automatic installation of the upper frame to frame machining center with pallets to reduce exchange rate to minimize the centrifugal force generated during rotation to reduce the distance between the upper and lower pallet rotation axis Grab settled by giving the central shaft and driving the top from where the palette relates to a pallet changer, as an automatic pallet changer for machining centers, of a pair are spaced apart on both sides provided so as to extend vertically from the flat bed column (17); Is coupled to the upper end of the pair of pillars disposed to extend in a horizontal upper panel (18); Pallets, with a pair of change-arm (1) for exchanging 14 extends vertically so as to lift and rotate integrally, and a vertical beam center shaft 11 and the lower end coupling (3); A top plate above the gear box 19 is installed in the center shaft 3 and the pinion is coupled (4) and a rack meshing with the pinion (5); A pair of cylinders mounted on the rack gear box 19 and extending horizontally so as to drive the rack (8); And, a gearbox is installed in the above configuration, characterized in that said cylinder is provided with a V W fall descent operation (6) by the oil pressure.
