This paper illustrates the universal lifting platform milling machine numerical control transformation of the design process, a more detailed description of the XK6130 universal lifting platform milling machine transformation part of the design and numerical control system design. Using 8031 as the CPU control system of signal processing by the I/O interface, and output the step pulse, through a gear reducer, drive the leading screw to roll, so as to realize the vertical movement of the feed. Reform process as follows: ( 1) the reformation of machine part, including the overall reconstruction scheme and vertical feed direction of reformation. Consisting mainly of ball screw pair and reaction stepper motor selection and calculation of vertical feeding mechanism assembly plan. ( 2) the electrical control design, including MCS-51 Series MCU and the expansion of the chip selection and electrical control diagram design.
