075mm, and clamp two flange end panel; (5) opposite clamp old plane; (6) 3 get labour of → of the speed that cut a head to be retreated quickly into → , stop to be gotten severally cut a head; (7) loosen old plane will tighten device first, again loose two flange end panel, stop machine, finish circularly. The machine tool can is in 3 times alone adjust position, also can circulate automatically. The machine tool has cooling system, slideway is used self-lubricating. Workpiece and cutting tool use cooling circulatory system, scrap to use puissant refrigeration to rinse. 1. Electric hardware machines a requirement according to the machine tool, set electromotor: (1) M1 lubricant electromotor, ～ 380V, 40W, 0.
17A; (2) M2 slips electromotor of a hydraulic pump, y112M-4-B34kW, 8.

5kW, 12.
6A; (8) electromotor of the head after M8, y100M-6-B5, according to demand of hydraulic pressure action, set relay of 4 switch of 15 10 19 electro-magnet, signal lamp, journeys, pressure and 11 or so pushbutton, accordingly, of this modular machine tool electro-hydraulic control appears very important. Fluid drive is easy obtain greater power and torsion, motion is delivered smooth, control is convenient, yi Shi shows automation, be in especially and complex automatic job comes true to circulate easily when electric control system cooperates to use. Modular machine tool is typical sequence control. We use ohmic dragon CPMlA PLC to control. Main circuit pursues (more complex, slightly) in, all electromotor all have breaker protection, communicate contactor control; PLC of power source of load of dc of power source of machine tool, illume, control, PLC power source, PLC communicates laden power source to all set transformer, can prevent mutual interference. Transformer one, 2 times side sets recloser protection each. Control circuit sets interlocking protection, handlers does not insert SB4 of person key pushbutton, or the back door before opening electric ark (door jacket has SAO of two doors switch) or by press SBO of emergency stop button, all will make of QFO of power source total breaker take off buckle coil to get report and tripping operation, protect person and equipment security. Additional, of the machine tool lubricate to reach the designated position with refrigeration, ability starts hydraulic pressure system. 2. Pushbutton circulates by the job after PLC controls principle work rough location, crock of left, right clamp drives slip speed, after approaching work, stop, back end face locates the crock relies on to decide workpiece old plane ahead, reach the designated position journey switch and bank power relay give out crock of left, right clamp to rely on signal slow. After relying on slow to reach the designated position, terminal journey switch and pressure relay issue signal, clamp of crock of clamp of back end face. After clamp, pressure relay gets report to signal, left, right, hind at the same time speed, labour enters working slip, retreat quickly, press close respective former a journey switch. So far, finish loop of a job. Need altogether 48 lose person point, 34 output are nodded (I ／ Q distributes a list slightly) . Choose unit of a 40 bits of CPMlA CPU, take 3 to expand, namely a CPMlA-40CDR-A-V1, take 3 CPM1A-20EDR1. Be burned out to avoid PIC to output a dot, outfit low-pressure breaker is imposed between a group of COM between output mouth and control component. The picture of a few paragraphs of echelon with contrast more fundamental only below controls a principle to make one analysis. (1) interlocking lock up with solution (ILILC) . Below circular mode of operation, the input is nodded 00004, 00005, 00006, 0007 must have a bit to close, and must be two hydraulic pump already all started. The method that solves this one problem is aid the Chang Kaifu of these two contactor contact to serve as PLC of bend of dot losing a person to lose population 00000 (namely 00000 be close) , that is to say CNT007 must close; All athletic slip all still must be in former, namely 20000 ～ 20005 close entirely. Be in only press right now press circular button 00008 ability can close, also be only when afore-mentioned conditions are all and contented, just can issue circular signal namely 20006 have output, this is circular condition. (2) lubricate automatically the control echelon graph of pump. Machine tool slideway must want to have lubricant, otherwise slideway wears away, clip course is calorific. Slideway still has certain sealing, because this lube flows,must want have constant pressure. For this, lubricant pipeline jacket has pressure relay, receive in 00311 on dot losing a person, assure to must always enough lube oil is measured even. SQ15 of fat face switch is set on fat face, receive in 00001 on dot losing a person, control echelon graph sees a picture 1. Controlling a principle is: When rerun of machine tool power cut, no matter be,circulate, should lubricate only systematic oil pressure is insufficient, 00314 dot losing a person does not close, in electrify instant, namely inside cycle of a scanning, as a result of special and auxiliary relay 25315 close, tally CNT007 by to clear. Below the case that has lubricating oil, 00001 " ON " , TIM008 " ON " , CNT007 " 0N " . Right now, output relay 01402 " ON " , , communicate contactor K1 coil to get report to suck close, m1 gets lubricant pump motor report runs. After 3s, of TIM008 often shut a dot to turn into " OFF " K1 breaks phone accordingly, m1 stops roll. When M1 is rotational, because oil pressure is elevatory, relay of oil pressure pressure often opens contact, close, 00311 by " OFF " turn into " ON " , tally CNT007 computation second. When oil pressure drops, repeat the process above again. When CNT007 computation 6 when, CNT007 has output, 01402 become " OFF " , ml turns no longer, until next time machine tool again the first time when getting report till. Lubricant pump runs 3s every time, move 7 times in all, can make sure machine tool slideway works continuously completely 4h above, lubricant and good. (3) former a programming. This is problem of experience of a design, must understand the athletic process of hydraulic pressure crock very much. Because 3 many axes get all sorts of hydraulic pressure jars,have 7, be like incorrect former programming undertakes clever processing, debug, move, happen likely to have ill case occasionally. Because as a result of a variety of reasons, for instance of electromagnetism a powerful person shut, of pressure relay shake etc, can cause hydraulic pressure crock to answer former when not certain every time politics pressing former the fetch when government office answers a Hang Chansheng Guo Lin but cannot let it bump into a crock again, reason is decided with this former. Accordingly, every is adjusting condition to fall, former a directive all by former of a journey switch close make former a signal lamp is bright (the program sees a picture 2) . Below circular condition, the design becomes another kind of software former a signal, if pursue,the Zun Ga of 2 is tightened former a signal. Return when left clamp crock former, no matter have,do not have super- former, press only closed former a journey switch 00009 " ON " , 20000 have output, lock up oneself; Advance when left clamp crock only, 01106 become " OFF " , 20000 ability by " ON " become " OFF " , without output; Crock of demonstrative left clamp is absent former. This kind of design, can adjusting condition to fall on one hand (do not suffer IC, ICL interlocking) whether to shine through observing 01006 signal lamp, will decide conveniently former a place of journey switch installation is proper; On the other hand, after can assuring to won't be pressed to close as a result of individual journey switch below circular condition again, oil cylinder journey has developed a head, ensure the loop is good. 3. Of electric equipment component choose (1) contactor of low-pressure breaker, communication, transformer main outside buy electric equipment component uniform the home made product that choose entrance product or accords with IEC standard. (2) working select switch chooses all-purpose transfer switch, adjust button uniform choose choice button. Such, starting a hole decreased greatly on operation face plate several, make operate simple palpability. (3) go up according to I/0 allocation graph and its circuitry connect a dot, when computation junction block, choose proper " connection " base, with benefit construction, safeguard. 4. Note (L) as a result of 3 a few at the same time much axis bore machines steel cast, generation quantity of heat is bigger, need puissant refrigeration, what cause each spacing accordingly is adjacent switch use environment is harsher, in was close to switch to become electric equipment element fragile, need to be safeguarded mainly. (2) this machine tool has system of two hydraulic pressure, reduced hydraulic pressure crock between the interference of pressure, but adjust when hydraulic pressure pressure and discharge, answer to be coordinated with electrical system well, produce the advantage of Electromechanical unifinication adequately. 5. Before use effect gets modular machine tool without 3 many axes, assembly of carapace of assembly of carapace of rear of completely suitable lorry and 11B rear all is to part by 3 above machine tool, by 3 people above ordinal complete 3 poriferous treatment, hold clip for many times, machine for many times finish, quality assures hard. After having this machine tool, manufacturing efficiency raises near 10 times, personnel decreases for 1/3, product quality also has assure. 1999 designed drilling machine of the first 3 many axes first quarter, classics use effect is very good. Use unit is back-to-back add signed contract of the 2nd design, drilling machine of two 3 many axes are used all the time up to now. CNC Milling
