Problems solved by technology

[0003] At present, the column of CNC machine tools is mainly made of cast iron. The casting process is relatively complicated, the development and manufacturing cycle is long, and the cost is high, which makes it difficult to meet the needs of CNC machine tools for delivery. The welding process with high capacity utilization rate and relatively low environmental pollution rate is adopted. Bed design and manufacturing has become a development trend

Abstract

The invention relates to a stand column of a vertical numerical control machine tool and a manufacturing method of the stand column. The stand column of the vertical machine tool is formed by a frontwall, a first side wall, a rear wall and a second side wall together, a guide rail base is arranged on the front wall, a first guide rail and a second guide rail which are parallel to each other are arranged on the outer surface of the guide rail base, and the guide rail base and the front wall are integrally cast and formed. The guide rail base and the front wall are integrally cast and machined,so that the local rigidity of the guide rail base is improved while the precision of the guide rails is guaranteed. By means of the stand column structure which combines casting with welding and is mainly formed through welding, the influence of welding stress and deformation on the rigidity of the guide rails is avoided, and meanwhile, the uniformity of the material and performance of guide railsupporting parts is ensured.

Description

technical field [0001] The invention relates to the field of numerical control machine tools, in particular to a tube-sheet structure column of a high-precision vertical numerical control machine tool based on a casting-welding composite process and a manufacturing method thereof. Background technique [0002] CNC machine tools are the "working machine" and basic equipment of the high-end equipment manufacturing industry, and are widely used in aerospace, automobile, strategic emerging industries, and national defense and military industries. The technical level and inventory of CNC machine tools have become an important indicator of a country's manufacturing level, industrial modernization and national comprehensive competitiveness. The self-sufficiency rate of my country's medium and high-end CNC machine tool industry is seriously low. There is still a big gap between the machine tool industry and the world's advanced countries in design and development, material technolog...
