CA6140 车床主轴箱的设计 摘要在工业生产的很多时候都要用到 CA6140 车床，然而，这种车床的自动化程度不高，结构又相对复杂，如果要加工一些相对复杂的工件，就需要不断换刀，给实际操作带来很多麻烦，再加上这种车床的加工过程较慢，造成效率不高，所以，只能在单件或者小批量生产中广泛应用。本文主要对该机床的主轴箱进行了设计，采用三轴支撑的滚动轴承，加上双轴滑移的共用齿轮作为进给体系；加上快速电机和十字手柄，极大改善了机床的性能，提高了操作性。本文从 CA6140 机床的参数设定、传动体系图制定、传动方案制定，主要零部件的校荷，对该机床的主轴箱设计进行了说明，并附有机床了零部件整体装配详图。关键词：CA6140 机床；主轴箱；零件；传动； AbstractThe scope of application of CA6140 lathe is very extensive, but the complex structure and low degree of automation, the workpiece processing is more complicated in shape, change the knife trouble, in the process of auxiliary time is relatively long, low productivity, suitable for single or small batch production. The main shaft three support adopts the rolling bearing; the feed system uses the two axle sliding common gear mechanism; the longitudinal and transverse feed is controlled by the cross handle. The machine has good rigidity, large power and convenient operation.As a major turning processing machine, CA6140 machine is widely used in mechanical processing industry, the design of the main spindle box for CA6140 machine design, design is the main content of the main parameters of the machine, drawing up the transmission plan and the transmission scheme, the main parts of the calculation and checking, the use of CAD drawing software design and processing of parts.Keywords: CA6140 machine tool ；spindle box ；parts ；transmission 目 录第 1 章 引言........................................................5第 2 章 主要技术参数................................................6第 3...
