我厂生产的Y54A插齿机在使用中常发现有不让刀或让刀量不足的毛病,这主要是外界空气渗漏到工作油缸、排气不畅引起的。针对这一缺陷,我们在推动工作台的压力油缸盖上增加了一个排气螺钉。或叫排气阀,其结构如图所示,机床开动以后,把放气螺钉A松开,渗漏到油缸的气体便从排气针孔排出,随即有少量压力油喷出,再将螺钉A扭紧,机床即可正常工作。 改装时,把油缸盖从机床上拆下来,在避开油 Y54A Gear Shaping Machine I produced in the factory often found in the use of the knife or knife to prevent the lack of problems, which is mainly outside the air leakage to the working cylinder, caused by poor exhaust. In response to this defect, we have added an exhaust screw to the pressure cylinder head that drives the workbench. Or called the exhaust valve, the structure shown in Figure, the machine starts, the deflation screw A release, leakage to the cylinder gas will be discharged from the exhaust pinhole, then a small amount of pressure oil spray, and then the screws A Tight, the machine can work properly. When retrofitting, remove the cylinder head from the machine and avoid the oil
