摘 要

本课题拟设计一套基于工控组态软件MCGS和可编程控制器的可调式芯棒磨柄机监控系统,使用机器磨削取代传统的人工砂轮磨削,实现安全、稳定、高效地对芯棒进行斜槽磨削。在加工过程中,上位机监控系统能够通过自动和手动两种方式控制硬件系统各设备的开关和运行状态;根据加工效率要求,设置进料速度、砂轮磨削数及磨削时间等加工参数,若磨削过程中失败,能够及时声光报警提醒工作人员进行检查,确保安全加工;该监控系统采用工控组态软件MCGS和可编程控制器PLC相结合方式,能够实现对锤柄芯棒进行自动、快速地磨削,大幅度提高生产效率,有效降低工人劳动强度,充分保证生产加工安全可靠。

在本设计之前大部分都是通过人为的去控制监测芯棒磨柄的生产,由于芯棒磨柄这项工作的工作量较大且产生的灰尘颗粒对人体会造成一定的伤害,所以本次设计就是为了减少现场工作量,保护人生安全,最大限度的提高工作效率。此外,将MCGS和PLC应用于可调式芯棒磨柄机监控系统的设计中还可以达到自动监控的目的,调试时以可直观、形象地看到问题所在。同时PLC 程序设计不需要复杂的计算,降低了其系统成本。

Design of monitoring system for adjustable mandrel grinding machine

Abstract

Adjustable mandrel grinding machine monitoring system handle this project intends to design a set of configuration software based on MCGS and the programmable controller, use the machine to replace the manual grinding wheel grinding tradition, to achieve safe and stable and efficient grinding on the mandrel chute. In the process, the PC monitoring system can switch and control the hardware system by manual and automatic two ways; according to the requirements of the processing efficiency, set feed speed, grinding wheel and grinding time and other processing parameters; if the fault occurred in the grinding process, can give an alarm to remind workers to check and to ensure the safety of the processing; monitoring system using MCGS configuration software and programmable controller PLC combination, can realize automatic and fast grinding on the hammer rod, greatly improve the production efficiency, reduce the labor intensity of workers, and fully guarantee the safety and reliable production and processing.

In the design before mostly through the artificial control to handle the production monitoring mandrel grinding, grinding mandrel because this work handle larger workload and dust particles will cause some harm to the human body, so this design is to reduce the workload, protect life safety, maximize the work efficiency. In addition, the application of MCGS and PLC in the monitoring system of adjustable mandrel grinding machine can also achieve the purpose of automatic monitoring. When debugging, the problem can be seen visually and visually. At the same time, PLC programming does not require complex calculation, reducing the cost of the system.

Key words: adjustable; MCGS;PLC; mandrel grinding;
