Abstract
With the development of modern information techniques, the high automation with the main purpose of improving the production efficiency of product process and the accuracy with the accuracy with the main aim of improving the quality of product have been becoming the two major directions of the modern technique of mechanical process. People on the air machines, CNC machine tools, precision instruments and meters and all kinds of sophisticated machinery and equipment raised higher and higher precision, XY for Taiwan is that these high-precision machining equipment to achieve the core components, for improving the quality of processed products play Is particularly important role.
The servo system designed to control the servo motor to the transmission system into the NC machine tools, including screw and nut bearing components such as vice, is about to servo motor for the transfer of rotating turret of the table or feed the entire campaign mechanical transmission chain. The entire mechanical transmission chain for the system design, servo motor related to the selection, the selection of ball screws, checking strength and production design should pay attention to the problem of connecting the servo motor and the ball screw of the axis The Selection and Verification, bearing pieces bearing the design, rail and rack design. Through the table mechanical transmission chain system design to meet the machine into the system to the positioning accuracy and static and dynamic performance, so as to ensure the accuracy of processing machine.
Keywords XY table; servo system; CNC machine tools
