摘  要

该篇论文为镗主轴箱的6个轴孔的变速箱组合镗床设计。镗床是主要用镗刀对工件已有的预制孔进行

镗削的机床。通常以镗刀旋转为主运动，镗刀或工件的移动为进给运动。它主要是用于加工高精度孔

或一次定位完成多个孔的精加工，此外还可以从事与孔精加工有关的其他加工面的加工。使用不同的

刀具和附件还可进行钻削、铣削、切削，其加工精度和表面质量要高于钻床。镗床是大型箱体零件加

工的主要设备，也可加工螺纹及外圆和端面等。
以箱体零件同轴孔系为代表的长孔镗削，是金属切削加工中最重要的内容之一。尽管现在仍有采用镗

模、导套、台式铣镗床后立柱支承长镗杆或人工找正工件回转180°等方法实施长孔镗削的实例，但

近些年来，一方面由于数控铣镗床和加工中心的大量使用，使各类卧式铣镗床的坐标定位精度和工作

台回转分度精度有了较大提高。从机床结构上使工作台回转180°自定位的调头镗孔，几乎是成为了

在该种机床上镗削长孔的唯一方法。
本设计说明书主要包括了组合机床总体设计过程，对工艺方案设计、总体设计、部件设计等几方面加

以论述。
内容有产品工序分析，组合机床总体布置以及镗床主轴图的绘制。

关键词：主轴箱；组合镗床；加工工艺

 Abstract

    Gearbox combination boring lathe design this paper into 6 hole boring spindle box.

Boring machine is mainly used for boring prefabricated holes on the workpiece has been

the boring machine. Usually, boring cutter rotating main movement, the workpiece moving

boring or for feed motion. It is mainly used for finishing machining high precision hole

or a location to complete a plurality of holes, in addition to engage with the hole

machining processing and other related processing surface.Different tools and

accessories used can also be drilling, milling, cutting,, the machining precision and

surface quality than that of drilling machine. Boring machine is the main equipment of

large body parts processing. Can also be processed the thread and the outer circle and

end.
    Long hole boring to box part coaxial holes as the representative of the cut, is one

of the most important content in the metal cutting. Although there are still using

boring mode, guide sleeve, desktop milling and boring machine after the columns support

the long boring bar or artificial alignment workpiece rotation of 180 DEG, examples of

long hole boring. But in recent years, on the one hand because of the extensive use of

CNC milling machine and machining center, precision of the coordinate positioning rotary

precision and working table of horizontal boring and milling machine has been greatly

improved. From the machine tool structure enable the rotary table 180 ° from the

positioning of the turn-around boring, become almost the only method in the machine tool

on the long hole boring.
    This design instruction booklet mainly includes overall design process of machine

tool, and discusses the aspects of design, process scheme for the overall design,

component design.
    The contents of product process analysis, combination of general layout of machine

tool and boring spindle diagram.

Key words: spindle box; combination machine; processing technology
