摘要

鏜床是指主要用鏜刀在工件上加工已有預(yù)制孔的機(jī)床。通常，鏜刀旋轉(zhuǎn)為主運(yùn)動(dòng)，鏜刀或工件的移動(dòng)為進(jìn)給運(yùn)動(dòng)。主要用于加工高精度孔或一次定位完成多個(gè)孔的精加工，此外還可以從事與孔精加工有關(guān)的其他加工面的加工。
按結(jié)構(gòu)和被加工對(duì)象分
(1) 臥式鏜床：鏜軸水平布置并做軸向進(jìn)給，主軸箱沿前立柱導(dǎo)軌垂直移動(dòng)，工作臺(tái)做縱向或橫向移動(dòng)，進(jìn)行鏜削加工。這種機(jī)床應(yīng)用廣泛且比較經(jīng)濟(jì)，它主要用于箱體(或支架)類零件的孔加工及其與孔有關(guān)的其他加工面加工。
(2) 坐標(biāo)鏜床：具有精密坐標(biāo)定位裝置的鏜床，它主要用于鏜削尺寸、形狀、特別是位置精度要求較高的孔系，也可用于精密坐標(biāo)測(cè)量、樣板劃線、刻度等工作。
(3) 精鏜床：用金剛石或硬質(zhì)合金等刀具，進(jìn)行精密鏜孔的鏜床。
(4) 深孔鏜床：用于鏜削深孔的鏜床。
此外還有能進(jìn)行銑削的銑鏜床，或進(jìn)行鉆削的深孔鉆鏜床。
機(jī)械加工工藝中的深孔通常是指工件長(zhǎng)度大于直徑5倍以上的孔，在其加工過(guò)程中存在著排屑、導(dǎo)向、冷卻與潤(rùn)滑等三大問(wèn)題。其加工的效率和質(zhì)量在經(jīng)過(guò)近一個(gè)世紀(jì)的發(fā)展，深孔加工技術(shù)以達(dá)到了較高的水平。
在以下的內(nèi)容里面將會(huì)對(duì)深孔鉆鏜床的床頭箱設(shè)計(jì)的介紹，其中包括：傳動(dòng)設(shè)計(jì)的步驟與方法；蓋軸和齒輪的校核的設(shè)計(jì)，其中有軸和齒輪的接觸疲勞強(qiáng)度和彎曲疲勞強(qiáng)度的校核；以及軸承的選用；三角皮帶的選用等等。

關(guān)鍵詞：鏜床；深孔加工技術(shù)；軸；床頭箱；齒輪；軸承。

Abstract

Boring is boring knife used mainly in processing the workpiece has been prefabricated Hole Machine. Usually, the main rotary cutter boring campaign, Boring knife or the movement of the workpiece to the Progressive movement.Mainly used for high-precision machining positioning hole or a hole completion of the finished, It could also engage in a hole finishing with the other machined surface processing.
By the structure and processing of object ：
（1） Horizontal Boring Machine : Boring axis level layout and axially feed, spindle box columns along the rail before vertical movement, worktable do vertical or horizontal movement, Boring. This machine is used widely and more economical, It is mainly used box (or stent) parts of the drilling hole with the other processing-processing.

（2） Coordinate Boring Machine : Coordinate with precision positioning device boring machine, which is mainly used to Boring size, shape, the location of the special requirements of high precision holes, and can also be used for precision coordinate measurement, the model line, the calibration work.

（3） Finishing Machine : carbide or diamond, and other tools, precision boring for the boring machine

（4）
Deep-hole boring machine : Boring for the deep hole boring machine.

In addition to the boring and milling machine for milling, drilling or deep drilling and boring machine
Machining Technology of Deep usually refers to the length of the workpiece diameter greater than five times above the hole, In their processing exist BTA, the guidance, cooling and lubrication, and other three problems. Its processing efficiency and quality After nearly a century of development, deep hole processing technology to achieve a higher level.
In the following there will be content to the deep drilling and boring machine bedside box design presentation, including : Transmission design steps and methods; covered shaft and the gear check the design, these shafts and gears contact fatigue strength and bending fatigue strength of the check; and the selection of bearings; The triangle belt use, and so on.

Key words : Boring Machine; Deep processing technology; Axis; Bedside box; Gear; Bearing.
