文档介绍：数控车床四工位电动刀架设计
摘要:
数控车床今后将向中高当发展,中档采用普及型数控刀架配套,高档采用动力型刀架,兼有液压刀架、伺服刀架、立式刀架等品种,预计近年来对数控刀架需求量将大大增加。数控刀架的发展趋势是:随着数控车床的发展,数控刀架开始向快速换刀、电液组合驱动和伺服驱动方向发展。根据加工对象不同,有四方刀架、六角刀架和八(或更多)工位的圆盘式轴向装刀刀架等多种形式。回转刀架上分别安装四把、六把或更多刀具,并按数控装置的指令换刀。本部分主要对四工位立式电动刀架的机械设计和应用继电-接触控制系统控制部分的设计。并对以上部分运用CAD做图,对电动刀架有更直观的了解。最后的提出了对电动刀架提出了意见和措施。

Abstract:
numerical control lathe, will in future development, the middle-grade high when to by supporting, high-grade nc cutter revised by both cutting, dynamic type hydraulic cutter, servo cutter, vertical cutter etc varieties, expected in recent years on the nc cutter demand will increase greatly. Nc cutter is the development trend of the development of numerical control lathe, along with, nc cutter began to change cutters quickly and electrohydraulic servo bined driving and direction. According to different targets, have four processing cutting, hexagonal cutter and eight (or more) can dise-type axial outfit knife knife, and other forms. Turn the tool carrier separately installs four, six or more tools, and C equipment instructions change knife. This part of 4 Labour vertical electric mainly the mechanical design and application of cutting the relay - contact control system of control part of the design. And the above part of CAD do diagram, a more intuitive electric knife understanding. The final proposed to the electric cutter puts forward opinions and measures.
Keywords: nc cutter, electric cutter, four locations
引言
数控机床是集机械、电气、液压、气动、微电子和信息等多项技术为一体的机电一体化产品。是机械制造设备中具有高精度、高效率、高自动化和高柔性化等优点的工作母机。数控机床的技术水平高低及其在金属切削加工机床产量和总拥有量的百分比是衡量一个的重要标志之一。数控车床是数控机床的主要品种之一,它在数控机床中占有非常重要的位置,几十年来一直受到世界各国的普遍重视并得到了迅速的发展。我国数控车床从20世纪70年代初进入市场,至今通过各大机床厂家的不懈努力,通过采取与国外著名机床厂家的合作、合资、技术引进、样机消化吸收等措施,使得我有了很大的提高,其产量在金属切削机床中占有较大的比例。目前,国产数控车床的品种、规格较为齐全,质量基本稳定可靠,已进入实用和全面发展阶段。
尽管近几年我国机床工具行业已经取得了很大进步,但在当前国内外机床市场竞争极其激烈的形势下,我国的机床工具行业则显得竞争力不强,主要表现在我国是机床消费大低、产品构成依然落后、产品创新能力差、机床可靠性还有待提高等方面。
数控技术的应用不但给传统制造业带来了革命性的变化,使制造业成为工业
