设计简介
摘 要
镗床是一种在工件上加工孔为主的机床，通常用于加工尺寸较大、精度要求较高的孔。本文主要针对卧式专用镗床的主轴箱进行设计，以便达到提高生产效率，降低成本等功效。卧式镗床是应用最多、性能最广的一种镗床，适用于单件小批生产，而专用镗床更是针对特定的零件而进行设计的机床，它有利于减少成本、提高生产效率。
本文设计的专用镗床主轴箱一共拥有五级转速，采用滑移齿轮组实现变速。利用拨杆来推动滑移齿轮进行变速，从而使输入轴的转速能够进行合理变速满足输出轴要求的转速。本文主要进行了主轴箱的传动方案设计，其次进行了齿轮参数的计算以及轴类的参数设计。并完成装配图以清楚表示镗床主轴箱的参数以及零件布局。
此次所设计的简易镗床，具有结构简单、变速可靠、生产效率高等优点，它适用于加工孔距误差较小的孔系。
关键词：镗床，五级变速滑移齿轮，主轴箱。
Abstract
Boring a hole in a workpiece based on machine tools, machining is typically used in larger size, high precision holes. This paper mainly for horizontal boring machine headstock design, so as to improve production efficiency, reduce costs and other effects. Horizontal boring machine is the most widely used, the performance of the most widely used as a boring machine is suitable for single and small batch production, but boring is dedicated for a specific machine parts and design, it helps to reduce costs and improve productivity.
This design is dedicated boring headstock has a total of five speed gear set achieved using slip speed. Sliding lever to promote the use of shift gears so that the rotational speed of the input shaft speed can be reasonably satisfy the requirements of the output shaft speed. This paper conducted a transmission design headstock, followed by the design parameters were calculated and the gear shaft of the parameters. And complete the assembly drawings to clearly represent the parameters of boring headstock and parts layout.
The simple design of the boring, simple structure, reliable speed, high production efficiency, it is suitable for machining small holes in the pitch error.
Keywords: boring, five-speed sliding gear, the headstock.
