回转主轴箱由于具有精度高、占地少、成本低、效率高等特点,近年来在组合机床设计中得到越来越广泛的应用。本文介绍在设计制造组合机床回转主轴箱过程中,将不定方程的原理应用于回转主轴箱机构有关零部件的匹配和各种参数的选定,提高了回转主轴箱的分度精度,改善了工作性能。图1幅,表1个。 Due to the high precision, small footprint, low cost and high efficiency, rotary headstocks have gained more and more widespread application in the design of combined machine tools in recent years. This paper introduces the principle of the indefinite equation in the design and manufacture of the rotary headstock of a combined machine tool, the matching of parts and components of the rotary headstock mechanism, the selection of various parameters, the improvement of the indexing accuracy of the rotary headstock and the improvement of the work performance.
