Abstract The hydraulic control system plays an important role in combination machine tools,The hydraulic control system design is also important for combination machine tools design combination part,Do the hydraulic control system design,Help to promote the overall performance of the machine tool,And make the hydraulic power components of an effective and reliable operation.
This paper according to the current situation of the development of the technology and application field, and hydraulic control system characteristics, to determine the electro-hydraulic control system design analysis. Will the design parameters commitments to load, make sure the implementation of components of the parameters. Analysis of the hydraulic system design is the whole part of the mechanical design, it is the task of machine USES, according to the characteristics and requirements, using the basic principle of hydraulic transmission, draw up a reasonable hydraulic system graph, according to the implementation of components of the parameters to choose hydraulic components and the structure of the system of the specifications of the design. And then after the necessary checking to make sure the execution element of the hydraulic system. For hydraulic system of each loop the performance analysis, summarizes the machine processing line power of the head of a hydraulic system has the performance characteristics.
Now the production control system of the machining USES mostly is the electro-hydraulic control.The electro-hydraulic control is will electromechanical transmission and hydraulic system of combining the advanced control system.Determine the application of power system is designed to produce the right to head into the form, orientation, so as to satisfy all drilling/tapping/milling power to the head of the different processing control requirements, through the system the control requirements of the electrical control circuit design and PLC system analysis.
Key words: Machining; Power head;Hydraulic control; Electrical control; Programmable controller
