Summary: Basically discuss a stage to amount to the 28SV11T PLC application in bore center machine. Main component is craft flow of central station flow, deep Kong Zuan, bore with a reamer / flow of boring cutter treatment and change knife flow automatically to wait. Keyword: Function of fixed position of 28SVPLCVFD-V transducer PG05 1 foreword in recent years the stage is amounted to roll out much money PLC and communication module, among them PLC of 28SV transistor output is collected with its powerful pulse, pulse outputs a function, and the support that commands an instruction to substantial position is paid close attention to by huge, showed wide applied perspective. The application of 28SV11T lead plane on bore center machine, use output of built-in pulse of 4 200K high speed to control transducer of 3 V series (get stuck through patulous PG) the fixed position of speed and servo of a 3 water chestnut, the switch that makes its convenient in different process machines speed differently, assure to be in different treatment process, be like the bore, treatment precision in boring hole. Technological process of 2 bore machining center machines flow automatically to machine flow automatically to be divided again for 3 technological process, machine flow, deep Kong Zuan to machine flow and reamer & boring cutter to machine flow for central getting respectively, specific as follows: (1) center of X63=1X64=0 of of of Y20=OUTY30=OUTY40=OUT of of actuating signal of flow of central getting treatment gets servo to move quickly toward work way, to set workpiece coordinate at 0 o'clock (the center is gotten) speed of feed of servo of of Y0Y1, deepness is machined (the user can be adjusted) center of rotate speed of main shaft gets movement of feed of of Y55=1 of fluid of Y60=1 cutting to finish, coordinate of workpiece of fall back on at 0 o'clock, sole plate of oil pressure of ① ② ③ carries out movement of circumgyrate of circumgyrate movement flow to achieve servo feed rate, deepness machines feed movement to finish, coordinate of workpiece of fall back on at 0 o'clock, sole plate of oil pressure of ① ② ③ carries out movement of circumgyrate of circumgyrate movement flow to achieve servo feed rate, deepness treatment carries out automatic mode to issue of the flow that change a knife (2) servo of deep Kong Zuan of X63=0X64=1 of of of Y20=OUTY30=OUTY40=OUT of of actuating signal of flow of treatment of deep Kong Zuan moves quickly toward work way, to set workpiece coordinate at 0 o'clock (deep Kong Zuan) speed of feed of Y0Y1 servo, deepness pecks type bore to machine (the user can be adjusted) of Y55=1 of fluid of cutting of of Y61=1 of deep Kong Zuan of rotate speed of main shaft gets movement of feed of of Nextpage of start of handle aperture head to finish, coordinate of workpiece of fall back on at 0 o'clock, sole plate of oil pressure of ① ② ③ carries out movement of circumgyrate of circumgyrate movement flow to achieve servo feed rate, deepness pecks type bore treatment to get movement of feed of start of handle aperture head to finish, coordinate of workpiece of fall back on at 0 o'clock, sole plate of oil pressure of ① ② ③ carries out movement of circumgyrate of circumgyrate movement flow to achieve servo feed rate, deepness pecks type bore treatment to get start of handle aperture head to carry out automatic mode to issue of the flow that change a knife (3) way of past work of servo of boring cutter of & of reamer of X63=1X64=1 of of of Y20=OUTY30=OUTY40=OUT of of actuating signal of flow of treatment of reamer & boring cutter moves quickly, to set workpiece coordinate at 0 o'clock (reamer & boring cutter) speed of servo feed, deepness machines (the user can be adjusted) movement of feed of of Y55=1 of fluid of cutting of of Y62=1 of boring cutter of & of reamer of rotate speed of main shaft is finished, coordinate of workpiece of fall back on at 0 o'clock, sole plate of oil pressure of ① ② ③ carries out movement of circumgyrate of circumgyrate movement flow to achieve servo feed rate, deepness machines feed movement to finish, coordinate of workpiece of fall back on at 0 o'clock, sole plate of oil pressure of ① ② ③ carries out movement of circumgyrate of circumgyrate movement flow to achieve servo feed rate, deepness treatment carries out automatic mode to issue the flow that change a knife to machine the that finish 2.
The 2 flow that change a knife change knife flow cent to issue the flow that change a knife and type of hand movable mould to play the circuit that change a knife for automatic mode two kinds. (1) from movable mould type servo of next the flow that change a knife carry out an origin movement (if be jumped over in origin) midway of mark of X15 origin reply changes Dao Huan to develop bit of X16ON to stop to answer origin movement to turn be slow fast next coming change a knife, detect X16ON of dot of the amortize that change a knife turns be slow fast next coming movement of calm angle of executive main shaft of transducer of of X17ON of the dot that change a knife decides library of knife of of angle mark X51 upper part of main shaft of ongoing X57ON makes knife jar servo of of X20X30X40ON of loose knife movement carries out an origin movement X15 , affirm calm angle is normal, normal X20X30X40 still is condition of loose knife of the crock that hit a knife ON servo falls quickly, detect X16ON of dot of the amortize that change a knife turns for slow fast next coming of X17ON of the dot that change a knife hits knife crock to return library of X50ON knife to answer retreat X57ON (2) knife flow origin changes below type of hand movable mould: Library of knife library advancement, knife library of regressive, knife rotates, X21X31X41 of hard key-press of knife library fixed position is individual movement of loose knife of the crock that hit a knife, main shaft decides angle X15 to answer origin to indicate the dot that change a knife and main shaft decide angle to finish: Library of knife library advancement, knife is regressive, x17ON decides angle to indicate the dot that change a knife and main shaft decide angle to finish advancement of the library that reach a knife to reach the designated position: Alternant type soft key-press (on man-machine interface) movements of all loose knife of the crock that hit a knife (alternant type) , of X57ON of mark of X17ON calm angle changes knife dot and main shaft to decide angle to finish advancement of the library that reach a knife to reach the designated position condition of the knife that reach a pine is normal: Servo is executable slow fast fluctuation random nods (knife library is regressive former) : Hard key-press is individual servo of movement of loose knife of the crock that hit a knife is executable give speed fluctuation both hands to operate executable automatic mode to issue frequency control of Nextpage3 of the flow that change a knife and frequency control of fixed position control to use a stage to amount to V series transducer, anthology match PG05 coder to get stuck, the frequency that delivers pulse through PLC lead plane will control the rotate speed of transducer. Frequency of transducer of setting of the need when setting parameter dictates origin is inputted for pulse. Here, need general transducer [00-20] parameter is set for 4 or 6, in this application, transducer changes direction not to need a change, consequently set is 4. Other and necessary parameter, not be the emphasis that article archives shows, do not make here expatiatory. 3.
Function of 2 fixed position is in the flow that change a knife, the need before changing a knife turns cutting tool to a proper point of view first, in order to facilitate the capture with knife accurate library. The positional parameter of the flow that change a knife originates coder PG, following plan institute show principle of control of coder fixed position, main parameter expresses place to show as follows. Coder of graph of principle of control of coder fixed position PG parameter 4 last words amount to all sorts of 28SV PLC functions as the stage of patulous module roll out, its had better performance in the application of respect of bus line of network join, spot, function of along with fixed position, all these superior performance are adumbrative its wide application perspective.
