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
