摘要

组合机床是一种高效率专用机床，有特定的使用条件，不是在任何情况下都可以收到良好的经济效益，在确定设计机床前，应该进行具体的经济技术分析。加工同一个机械产品的零件，通常会有很多种工艺方案，进行加工工艺设计，不同的方案会有不同的经济效果，影响技术经济的因素有很多，有时技术指标先进的方案，经济指标不一定优越，因此，需要对技术、经济指标作综合评价，综合多数的意见，选出优化方案进行经济效果评价，如果满意即可决定。

组合机床总体设计—“三图一卡”①“被加工零件工序图”它是组合机床的设计的主要依据，它是制造使用，检修和调整机床的重要技术条件②绘制加工示意图，它是刀具夹具，多轴箱，液压电器装置设计及通用部件选择主要原始资料，它是调整机床，刀具及试车依据。③绘制联系和运动关系及检验机床各部件相对于位置及联系是否满足加工要求，通用部件的选择是否合适，并为进一步开展主轴箱，夹具等专用部件，零件的设计提供依据。④相对生产率计算卡，它用来反映机床的加工过程，完成这一动作所需要的时间，切削用量，机床生产率及机床负荷率。

One, preface Combine a tool machine work in, the varieties which slip a size of sport speed and direction andthe load bear all influence degree differently it work function.Especially in the work enter theprocess.Slippery the on the stage load of suddenly disappear causable of ex- hurtle and load ofthe period variety cause of the sport gravamen be steady, all is processed the surface quality ofpiece the influence, severity hour will cause the knife break.Request according to tool machinefactory in Dalian, the author adopts power key to match diagram and the analytical method establishment of the appearance space to combine the new liquid that the tool machine slips apedestal to press to drive system a from adjust to carry on the back to press to adjust soon dynamic state mathematics model of system.Pass a calculator numeral to imitate really and study.Analytical slippery the pedestal produce ago hurtle and exercise not steady reason and main impact factor, in order to improvement slippery the dynamic state characteristic of pedestal. Two, dynamic state mathematics model The liquid which combines tool machine to slip a pedestal presses to drive system a from adjustto carry on the back to press to adjust soon the work principle diagram of system,such as diagram I, to show.That system is the work circulation which uses to complete the work enter a stop a back quickly.When slippery pedestal work enter, 34 change to be placed in diagram to show a right toward the valve, the oil pump of provide hydraulic-pneumatic dint under thefunction which over flows valve look like ground to keep Heng settle, the oils liquid flows through to change toward the valve and adjust soon valve juniors into the oil urn of have no a pole chamber, push slippery the set be left shift;In the meantime, oil urn the pressure oil that if there is pole chamber, eject through from adjust to carry on the back to press valve and change to flow to return to fuel tank toward the valve.In this process, two one-way valves with overflowed to flow valve and always dont change original work appearance.Object that system so of complications not line system, for the sake of easy to study its dynamic state characteristic, build up a reasonable simple ntsdynamic state mathematics model which only emphasizes to consider main impact factor is particularly important12.Know from the theories the analysis with experiment the research:That system of process time be soon that the process which is far larger than to adjust valve is soonhorary, oil urn have no the pole chamber effectively accepts to press area very greatly, adjust soon valve export discharge of super adjust a reflection in a moment is slippery pedestal sport speed of the variety be pimping2.For openning widely and going deep into dynamic state characteristic of study the system, make research work can on the microcomputer availably carry on, this text to original model2 do further simplification, on thesupposition that adjust soon the valve outputs in the whole transition process of system Hengsettle of discharge, treat it as to flow a source.So, the structure sketch plan of the dynamic state model of system such as figure 2 show, it from oil urn, slippery set, carry on the back to press valve and unite connectors roads etc. to constitute from the Diao.This text in use of sign asfollows: S 1-flow a source, then adjust soon valve export discharge; Sel-the slippery set glide friction Sel-the slippery set glide friction C5, C6-the etc. effect liquid of tube road permit: R5, R7-take care of an etc. of road effect liquid Zu; V3, the V4-oil urn has no pole chamber and has a pole chamber the contents to accumulate; P3, the pressure which have no pole chamber and have a pole chamber of the P4-oil urn F-the slippery set bear a load, V-slip a pedestal sport speed.The this literary grace hard working rate key matches diagram and appearance space to fold a method establishment sport mathematics model of the system for cent. Power keys matching diagram is an effect to flow diagram, it is the energy which presses system to deliver a way, take actual structure as foundation, the function which uses concentration parameter the of sub- system relates to an abstract earths surface to show for the Zu a dollar Rand permits sex dollar C and sensitive faculty dollar I of three kinds of function dollar.Adopt thiskind of method sets up a mold physical concept clear, combine the appearance space analysis method can compare to accurately describe with analysis line system, that method is in the hour the area study complications the line system dynamic state characteristic not of a kind of valid of method. According to from adjust to carry on the back to press to adjust soon the main characteristic ofeach component of system and set up mold rule1, get figure 3 show of the power key of system match diagram.Each half arrowhead on the key in diagram means that the power fly to, 2 which constitute power change the quantity be a dint to change to measure(hydraulic-pneumatic P or function dint F) and flow to change to measure(discharge q or speed v).O crunode means in the system to belong to merge a conjunction, each dint of key changes to measure equality but flows ntsto change to measure it with is zero;1 crunodes mean in the system to belong to establish a conjunction, each key is upper-class to change to measure equality but dint to change to measure it with is zero.TF means a different energy form the transformation machine of, the TF bottom mark of the letter of alphabet mean that the dint changes to measure or flows to change to measure of conversion specific value.The short and horizontal Gang of key means that key ascend two change the cause and effect between quantities relate to.The whole arrowheadses mean a control relation.Permit the dint of sex dollar and sensitive faculty dollar to change to measure in three kinds of function dollar and flow to change to measure it have integral calculus or differential calculus relation, therefore, according to figure 3 can deduce to submit to havenine complications that the appearances change to measure not the line appearance square distance.This text to slippery pedestal the research of the dynamic state characteristic from slippery pedestal of ex- hurtle and exercise steady sex both side to commence, use four ranks certainly tread long Runge-Kutta method at IBM-PC microcomputer up carry on numeral to imitate really, imitate a true result to distinguish such as figure 4 with figure 5 show. Three, slip to hurtle before the pedestal Slippery before the pedestal hurtle phenomenon is what function at slip the load of on the stage suddenly disappeared( if drilled to deeply work circumstance) cause.In this process, the variety which slips two chamber pressure P3s and P4 of the load F, sport speed V, oil urn of pedestal can from the figure 4 imitate true result see.When the slippery pedestal evenly and soon exercises under the function of the load, the oil urn has no pole chamber oil liquid pressure higher.It came together a great deal of energy in the oil liquid.While loading to suddenly disappear, that chamber is hydraulic-pneumatic to immediately and quickly lower, the oil liquid turns into the process of low-pressure Tai toward system to release a lot of energies from the high pressure Tai and cause slippery pedestal the high speed pounds at forward.However, slip a pedestal of ex- hurtle to make an oil urn to have a pole chamber the oil liquid is press to cause to carry on the back to press to go up, thus the depletion drop one part of energies in the system, to slippery pedestal of front blunt certainly repress a function.Should see, in the system study, from adjust to carry on the back entrance pressure of press the valve and be subjected to an oil urn two chambers hydraulic-pneumatic comprehensive function.BE load a disappeared moment, from adjust to carry on the back the pressure of press the valve quickly rises, and stabilize the number which starts to carry on the back to press at the beginning in the Gao up.From the diagram it is thus clear that, from adjust to carry on the back to press to adjust soon the system is in a twinkling load to disappear oil urn carry the range that the pressure go up on oil urns back big in traditionally adjust soon system, so, its oil urn energy which have the oil liquid in the pole chamber absorption many;Result, slip a pedestal of ex- blunt the quantity adjusts system to soon want than the tradition small be close to 20%.It is thus clear that adoption from adjust to carry on the back a Chuang to adjust soon system conduct and actions to drive the slippery pedestal of system to have good characteristic in the aspects of hurtling before repress, among them from adjust to carry on ntsthe back to press valve to have very your work to use. Four, slip the exercise of pedestal steady While regarding as a load period of used for the slippery on the stage variety(if the Xian pares to process a circumstance), the sport speed which slips a pedestal wants to produce certain。motion.In order to process the request of quality at assurance, have to possibly let up its speed motion scope.Set out from the convenience discussed a problem, suppose a load by the sine wave regulation variety, get thus of numeral imitate a true result such as figure 5 show.Be showed from this that system and traditionally adjust soon system to have same variety regulation with very close of number.The reason is that the variety range of load isnt big, oil urn two chamber pressures also more and greatly didnt change, end cause from adjust to carry on the back a function of press the valve not enough obvious. Five, improve measure Study result enunciation, with from adjust to carry on the back to press to adjust soon system for drive the slippery set of system, its dynamic state characteristic surpasses to traditionally adjustsoon system.Want to reduce the ex- blunt quantity of slippery pedestal, must be load the disappeared moment quickly raises an oil urn have a pole chamber of carry on the back pressure;Want to raise the exercise of slippery pedestal steady to need to increase system of rigid, the main measure lies in the physical volume which lets up an oil liquid.Know from the structure of the system, the oil urn has a pole chamber to have with the row pipeline one very big capacity and show such as the figure 6 as.It of the existence delay with Shuai reduce from adjust to carry on the back a function of press the valve, also lowered system on the other hand of rigid, it limitted to hurtle characteristic and exercise the further improvement of steady ago.Therefore, the improvement slippery pedestal dynamic state characteristic can carry on from two paths:Namely change an oil urn capacity and change from adjust to carry on the back to pressvalve structure size.The comparison passed one true calculation and result of the imitate of parameter of the system structure can get:When oil urn have pole chamber and row pipeline thecapacity V4 together has no pole chamber with enter pipeline the capacity V3 of ratio from original of 5.5 change to 1, such as the figure 6 bs show, in the meantime, from adjust to carry on the back to press the valve valve Xin bottom to carry diameter is increase by the original 10 mms for the 13 mms, damping triangle slot side long let up a 0.7 mms from the original lmm, canmake slippery pedestal of ex- hurtle quantity to let up 30%, transfer the process obviouslyshortens for time and slip the exercise of pedestal steady to get to very greatly improve. Six, conclusion Imitate a true research through theories analysis and calculator, from adjust to carry on the back to press to adjust soon system Be combine a drive of the tool machine slippery pedestal system to have much of expansion use value.The main factor which influences a slippery pedestal dynamic state characteristic is oil urn internal structure with from adjust to carry on the back ntstopress valve of size.If as to its carry on a reasonable design, the dynamic state characteristic canmake to slip a pedestal is shown Zhao ground an improvement.Also explained adoption power in make to slip a pedestal is shown Zhao ground an improvement.Also explained adoption power incomplications not line is convenience valid of. In 1946 the first electronic accounting machine was born in the world, thisindicated the humanity created has been possible to strengthen and partially toreplace the mental labor the tool. It with the humanity these which in the agriculture, the industry society created only is strengthens the physical labor the tool to compare, got up the quantitive leap, entered the information society for the humanity to lay the foundation. After 6 years, in 1952, computer technology applied to the engine bed , the first numerical control engine bed were born in US. From this time on, thetraditional enginebed hashad the archery target change. Since nearly half century, the numerical control system has experienced two stages and six generation of development. The early computer operating speed is low, was not big to then science computation and the data processing influence, but could not adapt the engine bed real-time control request. The people can not but use numeral logic circuit to build to become an engine bed special purpose computer to take the numerical control system, is called the hardware connection numerical control (HARD-WIREDNC), Jian Chengwei numerical control (NC). Along with the primary devicedevelopment, this stage has had been through repeatedly three generations, namely 1952first generation of - electron tube; 1959second generation of - transistor; 1965 third generation - small scale integration electric circuit. In 1970, the general minicomputer already appeared and the mass production. Thereupon transplants it takes the numerical control system the core part, from this time on entered the computer numerical control (CNC)the stage (which shouldhave computer in front of the general two characters to abbreviate). In 1971, American INTEL Corporation in the world first time the computer two most cores part - logic units and the controller, used the large scale integrated circuit technology integration on together the chip, called it the microprocessor (MICROPROCESSOR),alsomightbe called the centralprocessing element (tobe calledCPU). The microprocessor is applied to 1974 in the numerical control system. This is because minicomputer function too strong, controlled an engine bed ability to have wealthily (therefore once uses in controlling the multi- Taiwan engine bed at th
