我这个比较准确Abstracts Electrical and hydraulic feed table composite The design table in the motor drive based on the hydraulic system is installed so that the common drive to achieve a straight line from the table feed Designed into the compound to the table in part by the ball screw drive motor， hydraulic cylinder by hydraulic drive， the second part by the connection Designed the mechanical structure of the table was designed to understand the institutions and the operation principle of the hydraulic The following areas: design of transmission of the table， mainly the use of ball screws; the overall structure of the design table to understand the strengths and weaknesses， take full account of the principal contradiction， merit-based selection; control system design， its applications become more familiar with the Stepper motor-driven feed location can be accurate but the drawback is the lack of output power， so consider the source of the hydraulic motor as the driving force and the stepper motor drive system into the compound， hydraulic feeding Although it is impossible to locate， but with high output power， the two complement each other， so that accurate feed motion can be Significant increase in production Key words electric hydraulic feed table composite
electrical and hydraulic compound nanopositioner This design is in the motor - driven magnetroheological on the basis of the installation of hydraulic system so that it is common to give impetus to magnetroheological line round feed the design of complex nanopositioner motor part by the ball screw drives hydraulic part by hydrocylinder actuaton magnetroheological， by the second part of the design of the main stage of the mechanical structure design， appreciating and hydraulic system There are several aspects: magnetroheological of the transmission mechanism design， mainly the application of the ball screw; magnetroheological blockmodel laryngofibroscopy design， understanding， take full account of the main controdiction， grpwth ystems; control system design， familiarize its application stepmotor feed can be accurate location but there are shortcomings is inadequate， so the output will be considered as a hydraulic motor power source and stepmotor of compound feed system hydraulic feeding， although they could not be located， but with high output force， pre-language educatiuon， so that the feed motion can accurately so that productivity has risen
