1The number controls the improvement that machine bed lubricate the system the controlThe machine bed lubricates the design of the system and adjust to try with maintain to maintain, having got increases machine bed process accuracy, extension machine bed service life etc. very much the very important function.But in the aspects of electricity control that lubricate the system, still exsits below problem:An is to lubricate the system work appearance supervise and control.Number control the machine bed control system inside to establish generally and only the fuel tank oil supervise and control, the in order to prevent provides the oil the shortage, but to lubricate the system appear easily of leak the oil, oil road stop to wait the phenomenon, cant on time do the reaction.Two is a lubrication to establishes circulation with give oil time one, result in easily wasted.The number under the different work appearance control the machine bed, the amount of lubricant of the demand is different, such as in stage in pause in bed in machine compare an amount of lubricant for needing that process the stage want to be little.Aim at the above circumstance, in count control machine bed electricity control system, to lubricate to control the part proceeded the improvement designs, supervising and control the work condition of the lubrication system every moment, toing guarantee the machine bed machine parts get the good lubrication, and can also according to the work appearance of the machine bed, automatic adjust to provide the oil, circulation time, to economize the lubricant. 1 Lubricate the system the work the appearance supervise and controlLubricate the system inside in addition to making the lubrication system provide the oil shortage because of the oil anticipates the depletion, fuel tank oil over little, familiar breakdown still contain oil pump expiration, provide the pipeline road stop, divide to flow the machine work falsely often, leak the oil to wait seriously.Therefore, establishes to descend to say the examination device in lubricate system, used for the work to pump to lubrication appearance puts supervise and control into practice to, avoiding the machine bed the work while lacking the oil appearance, affect the machine bed function with the service life. 1) Over carry to examine to used to carry to protect a dollar an importation for, combining its heat over carrying the order to be used as the system of PMC signal in power supply back track that lubrication pump, once lubricate the pump appeared to carry, the system of PMC can immediately examine and put paid to, make machine bed stopped the movement immediately. 2) The oil examines lubricant as the expendable goods, for this reason machine bed work after a period of time, lubricating pump lubricant inside the fuel tank will reduce 2gradually.If operate the personnel have no on time increase, be the lubricant inside the fuel tank arrive lowest oil, oil examination the switch acts immediately, combining to deliver this signal to PMC system the proceeding handles. 3) Pressure examination machine bed the adoption passes into the type concentrates lubrication system, only system work normal, each lubrication orders it can guarantee to get the pre-arranged lubricant.Once lubricate to pump oneself the work falsely often, lose efficacy, or is to provide to have in the oil back track a the place appears to provide the pipeline road stop, leak oil etc. circumstance, pressure in the system will present the abnormality.According to this characteristics, design at lubricate the pump to install the pressure examination switch exit, combine to input this switch signal into the PMC system, after every time lubricate pump work, check pressure in the system, once discover the abnormality then stop immediately the machine bed works, combining the creation report to the police the signal. 2 Lubricate the control between time and lubrication number of timesThe in order to makes the machine bed exercise the vice- wear and tear lets up, must at exercise vice- surface keep appropriate and detergent lubricant , then maintain the friction surface an amount of provides the oil to become oil .But the number control the lubricant that machine bed exercise vice- demand the deal is not too many, adoption continue provide the oil method since uneconomical too not reasonable.Because too many to provide the oil with provide the oil the shortage similarly harmful, will produce the additional calories, pollution with wasted.Therefore, lubricate the system to all adopt the periodical and quantitative period the work the method. Concentrate lubrication system oneself can install the microprocessor, used for exclusively the enactment lubricates to pump time of the ceasing with every provide oil time, lubricate pump cleft to work with the control, design the personnel to usually also borrow this to simplify own the procedure of PMC. But the machine bed is under the different work appearance, such as just switch on electricity the beginning start the stage in work and process the movement similar to made machine bed pause circulated because of adjust, examination work piece, machine bed to lubricate the oily demand eachly not.In install FANUC number control the machine bed of the system, usually pass the control lubricates time that pump the work to provide to the amount of lubricant that regulate, but, what habit consider is to lubricates the system to process in the machine bed the movement appearance descend of provide the oil method, but did not have regard for the other the work the appearance, like this, crash the bed be placed in other work appearance, lubricate the system an amount of lubricant for providing want the 么 not enough, wanting the 么 excessive. The machine bed leads the amount of lubricant of the demand look like and can use underneath formula calculation:( length+ move the route of travel) width K.Can see 3from the formula inside, the machine bed leads the lubricant of the demand measures to have something to do with should leading the axial ambulation distance of the 轨 .The number that Europe and America produce controls the system to measures with the route of travel mostly conduct and actions according to, control lubrication pump work, the cleft provides the oil, and provided the homologous parameter in system, the easy to machine bed manufactory pass the procedure of PMC to the lubrication pump proceed electricity control.But has no similar control method in FANUC a system, for the sake of can in installing a the 0 is of FANUCly the number controls machine bed, the adoption looks like of provide the oil method the control to lubricate to pump the work, we improved the lubrication the control part of electricity designs, letting control system can according to machine bed of concrete work the circumstance adjusts automatically lubrication pump work frequency with every work time, at machine bed pause hour appropriate the decrease provides the amount of oil, but appropriate increment for machine bed beginning to start work. Will lubricate now the work appearance of the pump be divided into three type, establishes respectively lubrication pump work time with frequency. 1) The machine beginning that open the machine bed starts the stage opens the machine, lubricating the pump to begin to work right away, continuing to provide oil a period of time, lubricating at this time the time T1 that pump the work compares the normal appearance descends of want long, in order to provide the enough lubricant in the in a short time, make the machine bed lead the. the top become quickly a layer oil .Lubricate pump circulate time be set up by PMC TMRB in the procedure instruction.Different from the instruction of TMR, from time that TMRB set up, the customer cant modify the adjustment as ones pleases. 2) Processing the stage in movement machine bed opens the machine hereafter, passing by to get empty to transport the line prepare the hot empress, entering the stable work appearance.Henceforth, control system control lubricate the pump intermittent work, to guarantee the machine bed lead the can get periodical, quantitative lubrication.Lubricate time of the every work in pump to be set up by PMC TMR in the procedure instruction with time of its ceasing.Time parameter that TMR set up, customer can in PMC data window way according to need the appropriate adjustment. 3) Stage in pause a time for treating processing or processing completing, machine bed usually being placed in pause working appearance, lubricating oily demand cowgirl reducing, therefore, needing on time adjusting controling way, appropriate extension lubricating pumping stopping work, to reduce its work frequency, from but reduce the oil article the depletion.When key of realizing is a machine bed to be placed in the pause appearance, the system how to have learned that.The number of FANUC controled to provide the signal MVX( F102.0), MVY( F102.1), MVZ( F102.3) in the system, useding for reflecting machine bed each axial ambulation appearance.If the signals appearance is a 0, express cowgirl machine bed stalk static motionless, if all 4ambulation stalk all static motionless, then express the machine bed to be placed in at this time pause work appearance.So, above only all signal appearance all for0, pass the design, the procedure of PMC changes automatically lubrication pump work and stop time.This time, lubricate the time T2 that pump the work to use with the time T3 of the ceasing all the instruction of TMRB set up, same, customer must not modify these two time parameter as ones pleases. 3 Lubricate to report to the police the signal handles1) Pressure excrescent the number controls to lubricate system as in the machine bed intermittent provide oil work method.Therefore, lubricate pressure in the system adoption periodical check method, at lubricate the pump the every work later on check.If appear the breakdown, if leaks oil, oil pump expiration, the oil road stops, lubricate the pressure in the system and then will descend or go up suddenly, this time should immediately compulsory the machine bed stops the movement, proceeding the check, in order to prevent the circumstances extends. 2) Oil over low handles habitually before the method is to report to the police with pressure abnormality the oil over low signal to signal to classify a type, be used as the urgent ceasing signal.Once the system of PMC receives the above signal, the machine bed enters the urgent ceasing appearance immediately, let servo system cut the power at the same time.But, with lubricate the system make the circumstance of the pressure abnormality different because the oil road stops or leaks the oil phenomenon, if lubricate to pump the oil inside the fuel tank not enough, short time affects the function of the machine bed not to the extent of, having no to need to make the machine bed stop the work immediately.But, after appearing this phenomenon, control system should on time show the homologous information, remind to operate the personnel on time increase the lubricant.If operate the personnel did not give complement in rule time, system will control the machine bed to enter the pause appearance immediately.Only have on time after supplying the lubricant, just allow to operate the personnel circulate the machine bed, continuing the work of the interruption.Aim at the oil over low signal, handles like this the method can avoid the occurrence the otiose shutting down, reducing the assistance processes time, especially at the time of processing the large molding tool.While designing, we classify the o
