A control cabinet of an electrochemical machining machine tool and a control system thereof

Abstract

The invention discloses a control cabinet of an electrochemical machining machine tool and a control system thereof, relating to the technical field of electrochemical machining methods and devices for mechanical structure parts. The control system includes two parts: a system hardware part and a system software part. The system hardware part includes a PLC, an A / D converter, a D / A conversion module, a touch screen, a sensor transmitter, a thyristor intelligent control module, a temperature controller, and a PH instrument. The system software part includes a preparation module, a machining parameter setting module, a working mode selection module, an operation monitoring module, a fault handling module, an analog quantity module, an automatic machining module, a manual machining module anda management module. The PLC and the touch screen are adopted and combined for design, so the control system is improved in reliability, stability and automation and the hardware structure of the system is simplified. Through the PLC control system, conversion of different machining modes and flexible arrangement of production processes can be conveniently and quickly realized and thus the adaptability of a machine tool can be greatly improved.

Description

technical field [0001] The invention relates to the technical field of electrochemical machining methods and devices for mechanical structural parts, in particular to an electrochemical machining machine tool control cabinet and a control system thereof. Background technique [0002] In the early 1970s, the former Soviet Union and Eastern European countries paid attention to the research on the control system of electrolytic machining. At this stage, the control system of electrolytic machining mostly used relay or instrument control. Subsequently, on the basis of the development of numerical control technology, simple numerical control technology was gradually adopted in foreign small electrolytic processing machine tools, such as the use of digital dial switches to preset given programs to realize position control and conversion. In the next few decades of development, foreign numerical control electrolytic processing equipment has made great progress. The electrolytic pro...

Problems solved by technology

In the next few decades of development, foreign numerical control electrolytic processing equipment has made great progress. The electrolytic processing machine tools put into production use digital automatic control systems, and microcomputer software is used to control the processing program. The mode also belongs to the traditional indirect control of constant parameters, which has no obvious advantages in improving the machining accuracy and surface quality.
