【摘要】：PC50型数控镗铣床是西安煤机公司从美国进口的数控机床,是公司加工摇臂、牵引部、连接架等部件的主要设备。经过二十多年使用,机床可靠性和加工精度降低,控制系统老化,故障高。本文在西安煤机公司PC50型数控镗铣床升级改造专项支持下,对升级改造的关键技术进行研究,使机床恢复到同类型新购设备相同的加工能力。本文主要从以下三个方面对机床升级改造过程进行论述:(1)检测PC50型数控镗铣床技术参数现状,综合分析,制定升级技术要求,完成总体机床升级改造整体方案设计。在此基础上,确定详细的机械单元维修、电气改造、升级改造方案。(2)研究制定详细的机床伺服驱动、数控系统升级改造方案,完成驱动电机、滚珠丝杠、轴承、测量等关键部件选型设计,选择合适的数据系统并开发调试。(3)针对机床升级技术要求,根据选配的全新数控、电气硬件,对机床电气控制部分进行设计,分析原有机床动作顺序与流程,完成机床辅助动作、保护装置、液压系统等功能单元的控制程序开发工作。本文所研究的升级改造技术,有效提升了PC50型数控镗铣床的功能和加工精度,达到了预期目标,也为西安煤机公司后续设备升级改造积累了经验。
[Abstract]:PC50 type NC boring and milling machine is imported from the United States by Xi'an Coal Machine Co., Ltd. It is the main equipment of the company to process rocker arm, traction part, connecting frame and so on. After more than 20 years of use, the machine tool reliability and machining accuracy are reduced, the control system is aging, and the fault is high. With the support of PC50 type NC boring and milling machine of Xi'an Coal Machine Company, the key technology of upgrading and transformation is studied in this paper, so that the machine tool can be restored to the same processing capacity as the same type of newly purchased equipment. This paper mainly discusses the upgrading process of machine tool from the following three aspects: (1) detecting the status quo of technical parameters of PC50 type NC boring and milling machine, synthetically analyzing, formulating the upgrade technical requirements, and completing the overall scheme design of upgrading and upgrading of the overall machine tool. On this basis, the detailed mechanical unit maintenance, electrical transformation and upgrading scheme are determined. (2) the detailed machine tool servo drive, numerical control system upgrade plan, drive motor, ball screw, bearing, The key parts such as measurement are selected, the suitable data system is selected and the debugging is developed. (3) according to the new NC and electrical hardware, the electrical control part of the machine tool is designed according to the technical requirements of the machine tool upgrade. This paper analyzes the sequence and flow of the original machine tool, and completes the development of the control program of the function unit of the machine tool auxiliary action, protection device, hydraulic system and so on. The upgrading technology studied in this paper has effectively improved the function and machining accuracy of PC50 type NC boring and milling machine, achieved the expected goal, and accumulated experience for the subsequent equipment upgrading and transformation of Xi'an Coal Machine Company.
