新型双柱立式车床设计与实验

摘要

Aiming at the traditional double column vertical lathe has the problems of the complex structure,column heavy and bulky beam,the speed of the rotary table can not be further improved,and so on,a new type of double column vertical lathe was designed to satisfy the premise of performance requirements in same applications.By the evaluation index as the values of the straightness,circle run-out,flatness and surface roughness of the processed part,the parts to be measured were processed for roughing and semi-finishing with the new double column vertical lathe and the same specifications of traditional double column vertical lathe C6235,the processed parts quality was analyzed comparatively.Result shows that the quality of roughing machine parts of the new double column vertical lathe is lower than that of the ordinary double column vertical lathe,but it can meet the necessary requirements of machining accuracy for vertical lathe machining parts.The quality of semi-finishing machine parts with the new double column vertical lathe is better than that of the ordinary double column vertical lathe.Therefore,the application of the new double column vertical lathe has good prospects.%在满足相同使用性能要求的前提下,针对传统双柱立式车床存在结构复杂、立柱和横梁笨重以及回转工作台转速无法进一步提高等情况,设计了新型双柱立式车床.以被加工工件的直线度、圆跳动、平面度和表面粗糙度值为评价指标,使用新型双柱立式车床和同规格的传统C6235双柱立式车床对被测零件进行粗加工和半精加工,然后对加工后零件质量进行比较分析.结果显示使用新型双柱立式车床粗加工后的零件质量低于普通双柱立式车床加工后的零件质量,但能够满足立式车床加工零件后所需达到的加工精度要求,半精加工后的零件质量优于普通双柱立式车床加工后的零件质量.因此新型双柱立式车床具有较好的应用前景.
