Description

Machine head assembly structure for machine tool Technical Field The utility model relates to the technical field of machine tools, in particular to a machine head assembly structure for a machine tool. Background The five-axis machine tool is a machine tool which has high technological content and high precision and is specially used for machining complex curved surfaces, and a workpiece can be machined by one-time clamping. If the five-axis linkage high-grade numerical control system is matched, the complex space curved surface can be processed with high precision, and the method can be more suitable for processing modern dies such as automobile parts, airplane structural parts and the like. The traditional aircraft nose highly regulation relies on manual mechanical device more, is difficult to realize quick accurate displacement control, especially inefficiency when multiplex spare processing or complicated process switch, and the connection of lead screw outside slider and lifter plate in the current aircraft nose is fixed structure, can not finely tune lead screw nut and lead screw and lifter plate's installation clearance, leads to machining precision poor, and the comparatively fixed dead plate of structure of installation section bar in the current aircraft nose, and for this reason, we propose a aircraft nose assembly structure for lathe.
