摘 要

PCB數(shù)控二軸鉆銑床是一種機(jī)電一體化的產(chǎn)品，是專用于PCB加工的一軸一聯(lián)動(dòng)數(shù)控機(jī)床。
本機(jī)床采用先進(jìn)的直線滾動(dòng)軌跡、高精度滾珠絲桿和交流伺服電機(jī)；涉及微電子、計(jì)算機(jī)、自動(dòng)控制、精密機(jī)械、圖像處理等多種技術(shù),綜合性強(qiáng)，知識(shí)、技術(shù)、資金密度高，適用于高精度PCB的成形加工。
本文對(duì)PCB機(jī)床的整機(jī)系統(tǒng)結(jié)構(gòu)、伺服進(jìn)給機(jī)構(gòu)、工作裝置、機(jī)電匹配進(jìn)行了討論和分析，特別是對(duì)整機(jī)系統(tǒng)結(jié)構(gòu)和伺服進(jìn)給機(jī)構(gòu)進(jìn)行了詳細(xì)的設(shè)計(jì)，主要包括機(jī)床動(dòng)力參數(shù)、整機(jī)的結(jié)構(gòu)布置、伺服系統(tǒng)的選擇以及滾珠絲桿、滾動(dòng)導(dǎo)軌、聯(lián)軸器、滾動(dòng)軸承、交流伺服電機(jī)、高速電主軸等關(guān)鍵零部件的選擇和設(shè)計(jì)。
除此之外還對(duì)冷卻系統(tǒng)，潤(rùn)滑系統(tǒng)等做了簡(jiǎn)單的選擇，因?yàn)楸敬卧O(shè)計(jì)之重點(diǎn)在于機(jī)械結(jié)構(gòu)以及機(jī)械傳動(dòng)系統(tǒng)，所以其他的像數(shù)控程序，變頻器之類的就省略了許多，盡請(qǐng)諒解！
關(guān)鍵詞： 數(shù)控機(jī)床，印刷電路板，伺服系統(tǒng)，機(jī)電匹配
















ABSTRACT

PCB NC two-shaft drilling-milling machine tool is a kind of mechanical-electric integrative product and the one-shaft linkage NC appropriative print equipment based on the machining of PCB (Printed Circuit Board).
The machine tool adopts advanced beeline rolling oriented track, high precision ball bearing screw shaft and AC servo electromotor technique, deals with many studies including micro-electronics, computer, auto control, fine mechanic sand image manipulation, its comprehension is strong and its knowledge, technique and found density is high. It is used to the milling and drilling of high precision PCB.
The article discusses and analyzes the holistic system structure, servo feeding organ, working organ, NC organ and machinery electricity matching, and has carried out detailed designing and studying of holistic system and servo feeding system mainly including the estimation of driving parameter of the machine tool, the design of holistic structure layout, the selection of servo system, and the selection and proofing of key parts including ball bearing screw shaft, beeline oriented track, crosshead, ball bearing, AC servo electromotor, principal axis.
In addition to the cooling system, lubrication system, and so do a simple choice, because this focus on the design of the mechanical structure and mechanical drive system, like the other NC procedures, such as the frequency converter to omit a lot, do Please understand!

Key words: NC machine tool，PCB，servo system，Machinery electricity matching
