C616卧式车床八工位数控回转刀架设计

【摘要】

数控加工的加工精度高，生产率高，能减轻操作者劳动强度、改善劳动条件，有利于生产管理的现代化以及经济效益的提高，它的发展和运用，影响着制造业水平高低，实现生产过程的数控化，已经成为当今制造业的发展方向，所以非常值得我们去研究。

本设计通过对八工位卧式电动控制刀架的工作原理的分析，确定了多种方案，综合考虑各种方案的优缺点、性价比后，采用电动回转刀架。其刀架机构的主要部件包括减速传动机构、刀架的抬起机构、锁紧与转位精定位机构等，控制系统软件包括控制系统的选择，控制系统软硬件的设计，收发信电路的设计等，设计中所采用螺杆抬起机构、端齿盘定位机构和单片机控制系统都计较经济实用，适合我们我国现阶段数控机床的发展需要。 【关键词】

[Abstract]

Machining accuracy of NC processing is high, high productivity, can reduce the operator's labor intensity, improve working conditions, conducive to the modernization of production management and improving economic benefit, its development and use, affects the level of manufacturing industry, the NC manufacturing process, has become the development direction of manufacturing industry, it is worth we are going to study.

This design through the analysis of the working principle of the eight station horizontal electric control tool, a variety of scheme is determined, considering the advantages and disadvantages of various schemes, the price, the electric rotary turret. The cutter mechanism mainly comprises a deceleration transmission mechanism, cutter lifting mechanism, locking and indexing precision positioning mechanism, control system consists of control system selection, design of software and hardware of the control system, the transceiver circuit design, the screw lift mechanism, the tooth disk positioning mechanism and a single-chip microcomputer control system each of them is economic and practical design, development suited to our needs in our country at the present stage of CNC machine tools.

Key word：The eight station, electric tool, automation, 8051 single chip microcomputer
