Summary: Regard badge engine numerical control as systematic lead plane with average PC, the pace uses pulse to move wide circuit and flowing fractionize line into electromotor drive power source, noumenon of numerical control lathe uses old general be open to traffic to the bed is transformed and add outfit collection 4 labour dynamoelectric tool carrier, what realize lathe thereby is muti_function low cost automation. Current, machine tool of economy numerical control remains our country market to need a capacity the biggest, the numerical control machine tool with highest sale. Use existing and unused old machine tool, change through numerical control transform, make its become 1 new efficient, much can machine tool of economy numerical control, it is a kind of effective method of dish of vivid capital that put an amount, also be one of road of automation of low cost implementation. The lathe of CK6130 small-sized numerical control that we develop is the exploration of this train of thought and practice. Lathe of small-sized numerical control of CK6130 of 1 job principle is mixed by system of personal computer numerical control two much comprise machine tool noumenon. When processing work, weave first the numerical control program of workpiece, reach the person of key of numerical control program with school feasible nucleus next numerical control device, dictate according to the program by numerical control device computation gives feed pulse series again, then muti_function NC board undertakes pulse allocation, after classics work is put or drive power source undertakes power magnifies, form the control signal of actuating device, the rotate speed that controls machine tool main shaft thereby, open stop, the athletic way of feed system, speed and displacement size, and the choice of cutting tool, refrigeration is opened lubricantly stop wait for a movement. The order that makes cutting tool and workpiece etc assist device to set strictly according to numerical control program, journey and parameter have the job, machine an appearance, dimension, precision to accord with the spare parts of the requirement thereby. Graph system of control of machine tool of 1 numerical control is overall plan this machine tool uses system of numerical control of 2 personal computer system of the open loop economy that control X axis, Z axis achieves two axes linkage control, can finish the linear interpolation of two coordinate. It basically enters electromotor drive power source, pace by personal computer, pace electromotor, muti_function NC interface board, the composition such as control circuit (graph 1) . Personal computer can choose IBMPC-286 above a kind of any personal computer and compatible machine, insert inside chamfer of its bus line on numerical control gets stuck, use the package of software of lathe numerical control of development, adopt work machine program clavier key person, put lay aside to put store in the work program that has report to protect a function implement in, raise the reliability that the system moves thereby, the CNC Machining of the workpiece that finish. The pace uses pulse to move wide circuit and flowing fractionize line into electromotor drive power source, the cheerful that enters electromotor with carrying the condition when high frequency energetically gives torsion, improve fast performance of the system, what can reduce the pace when low frequency to enter electromotor at the same time is oscillatory, make move stabler. Still have overheating in addition, exceed pressure, flow too reach owe pressure wait for protective function. Still used photoelectricity disaster to close in the system implement undertake keeping apart, in order to raise interference rejection sex of the system. The machine tool noumenon of lathe of numerical control of CK6130 of noumenon of 3 machine tools is improved by C615 of small-sized and common lathe and come, basically include feed transmission system transform, advocate of transmission system transform those who reach tool carrier structure to transform 3 parts. System of feed of axis of graph 2 2 transforms system of sketch map feed transform Z axis (fore-and-aft) feed system is shown 2 times like the graph, the feed box that demolishs primary machine tool, smooth board box, feed rod and guide screw, arrange the condition the Zun Duan in former guide screw into electromotor, the installing hole that uses case of feed of primary machine tool and pin Kong An assemble decelerate gear case. The pace uses gear of decelerate of one class gear, drive to use double chip gear into electromotor in order to eliminate gap. Replace former guide screw to find a place for with ball guide screw in position of former guide screw. Ball guide screw is used can tighten installation means beforehand, arise with because guide screw is self-prossessed,be being eliminated bend be out of shape, make guide screw is pulled press stiffness to have bigger rise. When the job, the pace does not have clearance shaft coupling and reducer casing to connect into electromotor classics, will procrastinate move torque to pass ball guide screw deputy, drive pull board edge greatly fore-and-aft reciprocate. X axis (transverse) feed system is in the pace into electromotor installation procrastinate greatly board on, via guide screw of ball of drive of decelerate of one class gear. Advocate of gearshift system transform photoelectricity coder is installed in ministry of main shaft back end, use electromagnetism clutch and band of slippage gear photograph, change the hand of C615 lathe classification gearshift is transformed for self-classification gearshift, make have an operation the characteristic with convenient simple structure, use at the same time double fast electromotor, with increasing gearshift progression further. Graph of structure of tool carrier of block diagram of flow of work of 3 tool carrier transform use collection 4 labour the ordinary hand that dynamoelectric tool carrier replaces former C615 lathe moves dislocation tool carrier, control by numerical control system. The tool carrier when the job is after the signal that gets personal computer to be sent, in executive process, personal computer of component report direction answers the dislocation of tool carrier every time, Huoer that changes Dao Jun to go up by tool carrier send current knife signal, undertake judging by personal computer, should show a knife after contented personal computer asks, answer to personal computer again send tool carrier locking and execute ending signal (graph 3) . System of this machine tool numerical control uses the functional characteristic of 4 lathe current PC, machine tool noumenon uses common C615 lathe, process designing uses chromatic full screen to show with man-machine interaction means. The machine tool is achievable CNC Machining online process designing, program examines, syntactic error correction, graph shows, emulation treatment, moving parameter is installed automatically, control a machine tool to rectify each to use treatment process. Have treatment the function of the complex form such as face of columnar, conic, circular arc, end panel, figuration, whorl and assorted face. Package of numerical control software is open model, obligate has interface, can expand function and implementation software upgrade, have the marked characteristic of low cost automation.
