主轴套筒毕业设计

摘要

机床主轴是机床的核心功能部件，传统机床主轴是通过中间的传动装置，如皮带、齿轮等带动主轴旋转而进行工作的。电主轴又称内装式电机主轴单元，其主要特征是电机置于主轴内部，通过驱动电源直接驱动主轴进行工作。由于电主轴将机床主轴的高精度与高速电机的电磁功能有机地结合在一起，省去复杂的中间传动环节，具有调速范围广、振动噪声小，便于控制，能实现准停、准速、准位等功能，不仅拥有极高的生产效率，而且能显著地提高零件的表面质量和加工精度。在机械制造业不断向高速、高精度、高智能化发展的今天，高速高精度电主轴已经得到了广泛的应用。

本论文主要是主轴套筒的加工工艺及制造，主要涉及主轴套筒的切削用量的选择，工件的定位装夹，加工顺序，结合数控加工等，分别进行工艺方案分析，机床的选择，刀具加工路线的确定，数控程序的编制，最终形成可以指导生产的工艺文件。在整个工艺过程的设计过程中，要通过分析，确定最佳的工艺方案，使得零件的加工成本最低，合理的选用定位夹紧方式，使得零件加工方便、定位精准、刚性好，合理选用刀具和切削参数，使得零件的加工在保证零件精度的情况下，加工效率最高、刀具消耗最低。在设计中主要用CAD以及Mastercam来体现了主轴套筒的三维造型以及加工过程。并且通过Mastercam的自动生成程序来减少实际生产过程的工艺设计时间。最终形成的工艺文件要完整，并能指导实际生产。

ABSTRACT

The spindle is the core of the machine tool functional unit, spindle is traditional through intermediate transmission device, such as leather belt, gear, etc and the spindle drive to work. Electric spindle and said loading in motor spindle unit, its are main the feature is motor spindle, through the drive in internal power supply direct driving spindle. Because electric spindle of machine tool spindle will high accuracy and high speed motor of the electromagnetic function together efficiently, save in the middle of the complex transmission links with speed, scope, the noise is small, easy to control the vibration, can realize must stop, accurate speed, allowed a, and other functions, not only with the high production efficiency, but also can improve the surface quality of parts and machining accuracy. In mechanical manufacturing to keep the high speed, high precision, high intelligent development today, high speed and high precision electric spindle has been widely used.

This thesis mainly is the processing technology of the spindle sleeve and manufacturing, mainly involves the spindle sleeve of selection of cutting parameter, also the positioning clamping, processing order, with CNC processing etc, are for process scheme analysis, the choice of the machine tool, cutting tool processing route, the determination of numerical control programming, and finally form can guide the production process documents. In the whole process of the design process, through the analysis to determine the best, process scheme, making parts processing, the selection of the lowest cost of reasonable positioning clamping style, making parts processing convenient, positioning precision, rigid, reasonable choice of cutting tool and cutting parameters, makes parts processing in guarantee the accuracy of the parts, processing efficiency is the highest, cutting tool consumption minimum. In the design of the main use CAD and Mastercam to reflect the spindle sleeve of 3 d modeling and process. And Mastercam through the automatic generation of program to reduce the actual process of production process design time. We finally formed process documents to complete, and can guide practical production.
