Design Of Archetype Machine Of Multi-functional CNC Milling Machine

With the constant development of science and technology, the system of numerical control is more and more good. The numerical control device is developed from NC to CNC gradually too, It high speed, High-efficient, High accuracy, High the characteristic and their module izations of dependability, intelligent, and integrated swiftness convenient to their in production become important role more and more in making flexibility. At present, our country has already obtained certain achievement in the research of the multi-functional numerical control milling machine. Our works is to carry on numerical control transform, redesign mechanical structures, install corresponding guide screw, slippery rails to it to one a set of ordinary milling machineses, And in addition, the computer system controls, make it become multi-functional numerical control milling machine.First of all, our structure to the ordinary milling machine survey and draw, then carry on three-dimensional modeling, On the basis of three-dimensional modelling, we redesign the installation position that offer the guide screw, slippery rail, In order to guarantee the precision, the design of the seat of bearing adopts the structure of a pair of bearings. And within the range of what the lathe is allowed, proper increasing X, the journeys of Y, Z axle, Have expanded the range of processing. Through the structure transformation to the milling machine, we have increased by 400 mms, have cancelled the complicated gear wheel transmission, Urge the transmission to enter to the system directly through the computer system controls the servo electrical machinery, Have improved the rigidity of a lathe, has reduced the error. Have improved the job performance of the lathe. To the processing of the complicated curved surface, we have designed a numerical control revolving stage in addition for better completion, Its can finish the linkages of three axles . The numerical control revolving stage is put in processing the platform, through toprocessing the linkage of the platform and numerical control revolving stage, We can process different kinds of work pieces .This computer ready-made microcomputer system, pass between industry controlling machine and axle the controls of control board more, The sport steps of numbers of axle, issue pulse speed and different the algorithm of mending is inserted ing who axle link more. The function situation of the workingbench waits for the device to feedback and import the sport controller directly through the encoder. This system of numerical control involves two sport of turning rounds and a lot of the algorithm of mending is inserted, Its part is including servo urging unit, position to feedback unit, error to compensate, electrically control etc.The whole control system realizes the unified management under windows environment through using DELPHI'S programming treatment. The structure of the procedure is rational, the man-machine interface is good, controls and realize to the speed of the servo electrical machinery, adjustment of the acceleration and servo parameter through the parameter, Easy to use.This text introduces systematically design process, the composition of the numerical control part and design of the procedure of introduction mechanical structure, etc.
