DPDT-1A型三坐标同时伺服平动头,安装在D6125型电火花成型加工机床上,除安装的要求,须对机床进行小的改动外,还必须重新装配主轴头。提高灵敏度,以满足平动头加工的必要条件,否则加工不稳,幅度较大的上下抖动,使悬挂弹簧片折断,以至无法工作。但在无条件购买或改装主轴头时,可采用下述办法,来弥补原机床主轴头灵敏度的不足。如图1示,用链条或用柔性弹簧钢丝2代替悬挂弹簧片,在摆臂杠杆4的另一端增设橡
DPDT-1A-type simultaneous three-axis servo translational head, installed in the D6125 EDM machine, in addition to the installation requirements, to make minor changes to the machine, you must also reassemble the spindle head. Increase the sensitivity to meet the necessary conditions for flat head machining, otherwise the processing instability, a large range of shaking up and down, so that the hanging spring piece broken, and even unable to work. However, unconditional purchase or modification of the spindle head, the following methods can be used to make up for the lack of sensitivity of the original machine head spindle. Shown in Figure 1, with a chain or flexible spring wire 2 instead of suspension spring piece, the other end of the arm lever 4 additional rubber
