LZ—208油压轴承内圆磨床是轴承厂家的主要生产设备之一.其电气控制部分是由二极管矩阵电路、三极管、继电器等上千个分立元器件组成的逻辑控制电路,稳定性差,抗干扰能力低.因此,在生产过程中,逻辑控制电路经常发生故障,无法保证连续稳定的生产.同时,需要经验丰富的维修人员排除故障.为了提高磨床的生产效率,我们和洛阳轴承厂有关同志一起研制了LZ—208磨床的微机控制器.采用微机控制器后生产效率显著提高,磨床停机率降低了80%,加工精度大为提高,生产成本大幅度下降.本文主要介绍微机控制器的硬件、软件部分的设计和操作中需要解决的问题. LZ-208 oil pressure bearing internal grinding machine is one of the main production equipment of the bearing manufacturer.The electrical control part is a logic control circuit composed of thousands of discrete components, such as diode matrix circuit, transistor, relay, etc., which has poor stability and anti-interference Therefore, in the production process, the logic control circuit often fails, can not guarantee continuous and stable production. At the same time, the need for experienced maintenance staff to troubleshoot.In order to improve the production efficiency of grinding machines, and Luoyang Bearing Factory comrades together The computer controller of LZ-208 grinding machine was developed.The production efficiency of the LZ-208 grinding machine was significantly improved, the downtime rate of the grinding machine was reduced by 80%, the processing accuracy was greatly improved, and the production cost was greatly reduced.This paper mainly introduced the hardware, Software part of the design and operation of the problems to be solved.
