ABSTRACT

The numerical control processing's working accuracy is high, the productivity is high, can reduce the operator labor intensity, the improvement work condition, is advantageous in production management modernization as well as the economic efficiency enhancement, its development and the utilization, are affecting the manufacturing industry horizontal height, realizes the production process numerical control, already became now the manufacturing industry development direction, therefore is worth us studying. this design through to eight location horizontal type electric control tool rest's principle of work's analysis, had determined many kinds of plans, after overall eva luation each kind of plan good and bad points, performance-to-price ratio, uses the electrically operated turret saddle. Its tool rest organization's major component including the reduction gear organization, the tool rest lifts the organization, to lock and to index the fine detent mechanism and so on, the control system software including control system's choice, the control system software and hardware's design, receives transmitting circuit's design and so on, in the design uses the screw rod to lift the organization, the end tooth plate detent mechanism and the monolithic integrated circuit control system haggles over the economy to be practical, suits our our country present stage numerically-controlled machine tool's development need. key word eight locations, electrically operated tool rest, automation, 89C51 monolithic integrated circuit.


Keywords eight locations, electrically operated tool rest, automation, 8051 monolithic integrated circuit.
