文档介绍：摘要
本文首先简要阐述了BL系列台式车床总体的设计方案,说明了机床设计的基本要求,确定了该台车的整体布局。接着重点介绍了该台车进给箱的设计方案,对涉及到的轴、轴承和齿轮进行了设计和校核,确定了箱体内各元件的布置和排列,并综合各方面的要求,按照优化设计的标准,对进给箱的箱体进行了设计。由于该台车是一种小型车床,主要是针对中小型的零件加工而设计的,不同的用户对其有着不同的要求,因此我们利用了UG CAD计算机辅助设计软件对进给箱的各零部件进行了参数化设计。在计算机辅助设计过程中,完成了进给箱零部件的三维实体建模、虚拟装配和二维工程图的绘制。抽象出了用于进行车床快速数字化设计的数字模型,为进行车床的快速数字化设计作好了准备。

Abstract
This text has explained the total plan of design of BL serial desk-top lathes briefly at first. Have proved that the basic demand that the lathe is designed, confirmed the whole overall arrangement of this desk-top lathe. Introduce the desk-top lathe enter give plan of design of case , designed and check the axle, bearing and gear wheel that are involved especially then,confirmed case decorating and permutation of ponent in the body, and synthesize the requests of various to the standard of optimization design, have designed the case body that entered to the case. Because the desk-top lathe is small-scale lathe, design to process the medium and small-scale parts users have different requestion for the desk-top lathes, so we utilize CAD software, CAD of UG to design every part of drivingstock by the parameter designing. In the course of CAD, finish the three-dimensional entity modeling, fictitious assemble and two-dimentional project drawing of picture of the spare parts. Abstracted the Mathematical model for designing the lathes fastly and digitaly, and prepared it for fastly and digitaly designing the lathes well.
Keywords: desk-top lathes drivingstock UG CAD
