程控车床与数控车床比较,其特点是控制系统简单、造价低,利用挡铁、插销板等可对机床进行快速调整,故广泛应用于多品种中批量、中等规格、较复杂的零件加工中。CK5863程序控制立式车床是专为电机厂设计的,用来加工JO_3型6～9号电机端盖的液压半自动车床。刀架重复定位精度在0.005mm之内,加工精度Ⅱ级。机床除装卸工件外,刀架顺序动作、主轴变速、进给速度变换、动力卡盘夹紧力的调节以及主轴准停等均能自动完成。为了适应电机端盖加工的要求,我们在设计中采取了一些措施,使该机床具备下列各主要特点:
Compared with CNC lathe, the program-controlled lathe is characterized by simple control system, low cost, quick adjustment of the machine tool by block iron, bolt plate, etc. It is widely used in the processing of batch, medium size and complicated parts in many varieties. CK5863 program-controlled vertical lathe is designed for the motor factory, used to process JO_3 type 6 to 9 motor cover hydraulic semi-automatic lathe. Tool positioning accuracy of repeat within 0.005mm, processing grade Ⅱ level. In addition to loading and unloading the workpiece machine, the turret sequence of movements, the spindle speed, feed speed change, power chuck clamping force adjustment and quasi-stop spindle can be done automatically. In order to meet the requirements of motor cover machining, we have taken some measures in the design, so that the machine has the following key features:
