數(shù)控臥式鏜銑床刀庫結(jié)構(gòu)設(shè)計
摘 要
九十年代以來,數(shù)控加工技術(shù)得到迅速的普及發(fā)展,高速加工中心作為新時代數(shù)控機(jī)床的代表,已在機(jī)床領(lǐng)域廣泛。
面對市場競爭的壓力,如何提高機(jī)械制造業(yè)的生產(chǎn)效率是為重中之重,而刀庫的出現(xiàn),促使減少了機(jī)械加工時換刀具所使用的時間,大大的提高了生產(chǎn)效率。數(shù)控臥式鏜銑床是一種具有自動換刀裝置和任意分度數(shù)控轉(zhuǎn)臺的數(shù)字控制機(jī)床,工件在一次裝夾后能自動完成幾個側(cè)面的的多種工序的加工。
數(shù)控機(jī)床及由數(shù)控機(jī)床組成的制造系統(tǒng)是改造傳統(tǒng)產(chǎn)業(yè)、構(gòu)建數(shù)字化企業(yè)的重要基礎(chǔ)設(shè)備,它的一直備受人們關(guān)注。數(shù)控機(jī)床以其卓越的柔性自動化的性能、優(yōu)異而穩(wěn)定的精度、靈捷而多樣化的給功能引起世人矚目,它開創(chuàng)了機(jī)械產(chǎn)品機(jī)電一體化發(fā)展的先河,因此數(shù)控技術(shù)成為先進(jìn)制造技術(shù)中的一項核心技術(shù)。另一方面,通過持續(xù)的研究,信息技術(shù)的深化應(yīng)用促進(jìn)了數(shù)控機(jī)床的進(jìn)一步提升。

CNC horizontal boring and milling machine tool structure design
Abstract
Since the 1990s,CNC machine technology has made the rapid and universial development,as a new era of the representatives of NC machine tools.
Faced with the pressure of market competition, how to improve the mechanical manufacturing industry production efficiency is the priority among priorities, and the knife, to reduce the mechanical processing tool changer used time, greatly improves the production efficiency. CNC horizontal boring and milling machine is a kind of automatic tool changer and arbitrary indexing turntable digital control machine tool, workpiece can automatically complete the various processes in several side in a fixture.
CNC machine tools and manufacturing system composed of CNC machine is an important equipment to transform traditional industries, the construction of digital enterprise, it has attracted a lot of attention. CNC machine tools to performance, the flexible automation excellence excellent and stable accuracy, celerity and diversified to the functional attracted worldwide attention, it pioneered the development of mechanical products mechanical and electrical integration precedent, so the numerical control technology is a core technology in advanced manufacturing technology. On the other hand, through continuous research, information technology applications to promote the further deepening of CNC machine tools.
According to actual condition,I introduce the chain knife library of robot hands cutter replacement plan after referencing to the vast library mechanical structure of the sword.According to the Mechanical Design,the Mechanical Principle and other relevant knowledge,there are some designs about JCS-013 type nc horizontal boring and milling machine tool store and I have drew the key parts of library using AutoCAD 2007.
