Abstract

A PLC control system for a lathe hydraulic system, mainly composed of a left clamping hydraulic cylinder, a middle lateral feed hydraulic cylinder, a right longitudinal feed hydraulic cylinder, an electromagnetic reversing valve, a speed control valve, a double pump, a one-way valve, a pressure reducing valve and pressure switch. Its control is more flexible, and it is easier for engineers and technicians to operate. The connection between the solenoid valve and the computer improves the automation of data processing and reduces the labor intensity of relevant staff. The modification of the PLC control system is relatively easy, there is no need to reinstall the components, and the wiring method does not need to be changed, and the cost is not very high. Moreover, the PLC control system has high operational reliability and low possibility of problems.

Description

[0001] Technical field [0002] The invention relates to a PLC control system of a hydraulic system of a lathe, which is suitable for the mechanical field. Background technique [0003] In the mechanical industry, traditional lathes still occupy a large proportion. The switching of some lathe tools is controlled by the hydraulic system, and the electrical part of the machine tool is controlled by contactors. This type of control system uses a large number of components, takes up a large space, and the circuit is complicated, prone to accidents, and maintenance work is not easy. The PLC control system of the lathe hydraulic system can solve these problems very well. Contents of the invention [0004] The invention provides a PLC control system for a hydraulic system of a lathe, the control of which is more flexible and easier for engineering and technical personnel to operate. The connection between the solenoid valve and the computer improves the automation of data process...
