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CAXA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 the future when the development to the high, middle-grade using universal type tool rest facilities, high-grade USES dynamic type head, with hydraulic head, servo head, vertical head etc varieties, in recent years is expected to CNC tool post demand will increase greatly. CNC tool is the development trend of: with the development of numerical control lathe, numerical control head began to rapid change knife, electrohydraulic combined drive and servo drive direction. According to the processing object is different, there are four square head, turret and eight (or more) location disc type axial loading knife rest, and other forms. Rotary head separately on the installation of four, six or more tool, and according to the numerical control device of instruction in knife. This part mainly four station vertical electric tool rest of mechanical design and application of relay - contact control system control part of the design. And the above part using
