MJ4220立式珩磨机是全液压传动。液压传动系统的合理调试、检修与保养是使该机床长期保持稳定使用的重要条件。该机床是由主轴旋转运动、主轴往复运动及主轴箱上下位置的调整运动所组成。现将有关调试方法及在使用中常见故障的排除方法介绍如下,供读者参考。一、油压的调整见图1、2。首先将安全阀2的调压手柄旋松,把Ⅰ、Ⅱ处的两根橡皮软管接头旋下后对调装上拧紧,升降换向阀10扳到B_2位置。这样压力油进来后经过阀10至油缸9内,油缸上升。阀2此时即
MJ4220 vertical honing machine is full hydraulic drive. Reasonable debugging hydraulic transmission system, overhauling and maintenance of the machine is to maintain long-term stability of the important conditions. The machine is composed of spindle rotation, spindle reciprocating motion and the adjustment of headstock up and down position. Now debugging methods and troubleshooting in common use of the following methods for readers reference. First, the hydraulic adjustment shown in Figure 1,2. First of all, unscrew the pressure regulating handle of the safety valve 2, screw down the two rubber hose joints at Ⅰ and Ⅱ, and then tighten the lifting and lowering valve 10 to B_2 position. This pressure oil after coming through the valve 10 to the cylinder 9, the cylinder up. Valve 2 is now
