M7130平面磨床原设计磨头垂直升降是依靠操作者用手摇动进刀手轮来实现的。手轮每转,磨头升降1.29mm。因此,当磨削的工件厚薄变化悬殊或机床清扫需上下全程移动磨头时,操作者很费力。为了减轻操作工人的劳动强度,提高机床的生产效率,我们对机床进行了如下的改装,经使用验证,效果良好,深受操作者欢迎。一、改装的基本结构附图所示是改装的基本结构图。蜗杆和蜗轮仍可采用机床上原来的零件。只需将原蜗轮按图示车一台阶孔,与离合器1装成一体,并将它翻转180°,装在轴上。离合器2借助活塞作用产生轴向位移。活塞由24E-10B电磁阀控制,并由弹簧支撑,这样即使在油泵关闭时,离合器1和2仍处于结合状态。齿轮离合 M7130 surface grinder original design vertical grinding head is relying on the operator to manually shake the feed hand wheel to achieve. Hand wheel per revolution, grinding head lift 1.29mm. Therefore, the operator is laborious when there is a great difference in the thickness of the workpiece being sharpened or when the machine tool is required to move the grinding head up and down. In order to reduce the labor intensity of the operators and improve the production efficiency of the machine tools, we have made the following modifications to the machine tools, which have been well received by operators since they have been validated and worked well. First, the basic structure of modified The figure shows the modified basic structure. The worm and worm gear can still use the original parts on the machine. Just turn the original worm gear into a step hole in the car according to the illustration and fit it with the clutch 1 and turn it 180 ° on the shaft. The clutch 2 generates an axial displacement by the action of a piston. The piston is controlled by a 24E-10B solenoid valve and spring-loaded so that clutches 1 and 2 are still engaged even when the pump is off. Gear clutch
