基于模块化设计的高性能五轴联动机床的设计

Design of High-performance Five-axis Linkage Machine Tool Based on Modular Design

针对目前国产五轴加工机床精度不高、可拓性弱、可靠性差的问题,开发一款性价比高的高性能五轴联动机床。基于模块化设计理念,采用数字化设计技术,对机床的整体结构进行了合理规划。该机床主要由底座、龙门架、摇篮工作台、鞍座、立柱、主轴箱、刀库7个模块组成。其中底座、立柱、龙门架等关键部件均为自主设计开发。完成了机床安装调试。测试结果表明,机床的加工精度及表面质量均合格,加工性能达到了设计要求,关键性能指标优秀,加工零件3D轮廓精度0.015~0.025 mm,机床刚性0.5 mm,操作维护方便。所设计的机床售价为每台100~120万元,仅为进口机床的1/3,价格优势显著;同时该机床具有一机多用功能,在满足企业生产需求的同时,有效提升了企业的市场竞争力,推动了制造业的高质量发展。

To address the issues of low precision,weak scalability and poor reliability of domestic machine tools,a cost-effective high�performance five-axis linkage machine tool is developed.Based on the modular design concept and digital design technology,the overall structure of the machine tool is reasonably planned.The developed machine tool mainly consists of seven modules:base,gantry,cradle workbench,saddle,column,spindle box,and tool magazine,wherein the tool base,column,gantry are independently designed and self-made.Installation and commission tests of the machine tool are carried out.The test results indicates that the performance of the machine tool meets the design requirements and the key performance indicators are excellent.The 3D contour accuracy of processed parts is 0.015~0.025 mm,the rigidity of the machine tool is 0.5 mm,and it is easy to operate and maintain.The price of the designed machine tool is 1~1.2 million yuan per unit,which is only one-third of that of imported machine tools,the advantage is significant;at the same time,the machine tool has multi�purpose functions,which not only meets the production needs of enterprises,but also effectively enhances their market competitiveness and promotes the high-quality development of the manufacturing industry.
