摘 要
ＣＢ3463—1型液压半自动转塔车床,主要用来加工汽车前桥零件—前轮毂,该种机床是采用大量中间继电器及时间继电器,并通过插销板的插孔预选来实现对机床各刀架动作的顺序控制。由于加工环境的变化,加上机床使用年限己久,导致机床故障率很高。而且因机床机、电、液一体化程度较高,电路接线繁杂,查找故障很困难,使维修比较费时费力,严重影响了生产正常进行。我们对机床的机械结构及精度进行检测,确认机床的机械刚性良好,液压系统工作较稳定,设备各项运动精度均在允许值之内。经分析以及实践证明:绝大多数故障是因操作面板矩阵电路中插销与插孔接触不良,继电器、开关元件、电磁阀元件等电气元件性能不良或损坏引起。
我国制造企业的生产、加工装备大多是传统的机床，用这种装备加工出来的产品在国际、国内市场上缺乏竞争力，影响到企业的生存和发展。所以必须大力提高机床的数控化率。对于机床拥有者来说，进行普通机床数控化改造，只需花费购买相同新机床30%～60%的费用即可获得相同的使用效果，并具有交货期短、性能稳定、设计风险小、可以充分体现用户意愿、使用与维护方便等诸多优点，所以机床的数控化改造不仅仅是当前必要和重要的行为，而且也将是一个长期发展的战略措施。

ＣＢ 3463 — 1 automatic turret lathe in the half of type hydraulic pressure, use to process the ex- hub in— in parts in ex- bridge in autocar primarily, should grow the engine bed is to adopt the mass in the center after electric appliances on time after electric appliances, and pass to put the pin knothole socket primary election to realize to each knife of engine bed an operative sequential control.Because processing the change of the environment, plusing the engine bed usage time limit F long, cause the engine bed fault rate very high.And turn the degree because of the machine of engine bed, battery, liquid integral whole higher, the electric circuit wiring is complicated, checking to seek the fault very difficult, make maintain the comparison take a lot of time hard to tackle, effected the normal progress in production seriously.We examine to machinery construction and accuracy progresses of the engine bed, confirming the machinery stiffness of the engine bed good, hydraulic pressure system the operate is more stable, equiping various runnings accuracy all at allow the value inside.Through the analysis and practice the proof: the great majority fault puts the pin in the face plate matrix electric circuit because of the operation is bad with socket contact, is bad after electric appliances, switch an etc. electricity a function or the failure causes.
The our country makes the production of the business enterprise and process the mostly traditional engine bed in material, using the product that this kind of material process out to lack the competition ability on nations, local market, effecting the business enterprise exist the sum deveolps.So must increases strongly the number of the engine bed control to turn the rate. To the engine bed own come to say, proceed the common engine bed the number control turn reform, an usage for needing costing purchasing new engine bed in homology 30% ～ 60% expenses can immediately acquiring homology effect, combine have deliver goods the period the short , capability the stabilization, the design the risk small Can well body now customer will, usage and maintenance convenience etc. many advantages, so the number of the engine bed controls to turn to reform to not only only is strategy measure that current necessity and important behavior, but also also will be a long-term development.
