The invention discloses a large gear and rack transmission type numerical control machine tool, and belongs to the technical field of numerical control machine tools. The large gear and rack transmission type numerical control machine tool comprises a foundation, two ground piles distributed left and right are arranged on the foundation, a column set is mounted on the ground piles, steel frames are placed on the column set, the column set comprises at least one column, a cross beam is erected between the two steel frames, guide rails and first racks are laid on the steel frames in the front-back direction, the cross beam is in sliding connection with the corresponding guide rails through sliding blocks, the cross beam is further in engaged connection with the corresponding first racks through a built-in motor with a gear, a carriage seat capable of moving left and right is movably mounted on the cross beam, and a first-stage lifting frame capable of moving up and down is movably mounted on the carriage seat. The numerical control machine tool is high in adaptability, high in machining precision, stable in machining quality and high in production efficiency.
Description
technical field [0001] The invention relates to the technical field of numerical control machine tools, in particular to a large rack and pinion transmission type numerical control machine tool. Background technique [0002] With the rapid development of social production and science and technology, mechanical products are becoming more and more sophisticated and frequently modified, especially for mechanical parts required in aerospace, shipbuilding, military and other fields, which require high precision, complex shapes, and small batches. Processing such products requires frequent modification or adjustment of equipment, and ordinary machine tools or highly specialized automatic machine tools can no longer meet these requirements. In order to solve the above problems, a new type of machine tool - CNC machine tool came into being. This new type of machine tool has the advantages of strong adaptability, high processing precision, stable processing quality and high produc...
