ABSTRACT
The paper research the overall project design of the BL series horizontal lathe and introduce the function, feature and relationship of the every unit .A large deal basis task of the BL series horizontal lathe’s digitilized design are summarized. The paper also carry on discussion to general thoughts and processes of parametric modeling technology,the structure design of the lathe feet and shield .At the same time, the paper plished the CAD devise of the belt transmission and the strength size putation of the brake in the BL series horizontal cooling ,lubrication and protection methodology are also summarized in this paper. The paper utilize strong function of UG software,based on the entity’s modeling, created the lathe bed and shield of the BL series horizontal lathe on the developing platform of UGⅡ with the modeling and the relevance modeling tool among any unit,pleted dummy assemble and the drawing of the lathe feet and shield. As a result,it revise convenient according to user's enquiry and avoid repetition work in the process of designing .It make BL series horizontal lathe design more accurate and faster.
