为适应多品种、小批量、短周期生产形势的需要,机床夹具应具有可调整或重新组合的功能,以确保其取得良好的经济效益。因而,国内、外各工厂均大力推广通用可调整机床夹具及组合机床夹具。但毕竟通用可调整机床夹具的结构型式复杂,其设计及制造周期较长,且使用中调整繁琐,难于即刻上马;而组合夹具则因其元件之品种,数量有限,组合精度及其刚性均较差,难于保证较高精度工件的加工要求。从而,为适应上述生产形势的需要,国内各工厂应立足于本企业的生产条件,采取适当的技术措施将现有
In order to meet the needs of multi-species, small-batch and short-cycle production, machine tool fixtures should have the function of adjusting or recombining to ensure their good economic benefits. Therefore, domestic and foreign factories are to promote universal adjustable machine tool fixture and the combination of machine tools. But after all, universal adjustable machine tool fixture of the complex structure of the design and manufacturing cycle longer, and the use of cumbersome adjustment, it is difficult to immediately start; and the combination of components because of its components, a limited number of combinations of precision and rigidity than Poor, difficult to ensure the processing requirements of the workpiece with higher accuracy. Therefore, in order to meet the needs of the above production situation, the domestic factories should be based on the production conditions of the enterprise, take appropriate technical measures to the existing
