清理滚筒门锁紧机构的小改进 Q3113A型抛丸清理滚筒门锁紧机构中导向轴与门体上的导向轴孔成H9/f9配合。由于没有防尘措施,导向轴动作又频繁,门体上的导向轴孔很容易被磨偏,并在导向轴与轴孔间产生间隙,使之成为铁丸和尘土进入门体的主要通路。因此,锁紧机构各零件很快磨损,增加了维修工作量。有时铁丸与尘土卡在导向轴与轴孔间,导向轴难以动作,造成滚筒门锁紧失灵,影响滚筒正常工作。针对 Cleaning cylinder door locking mechanism of small improvements Q3113A type shot blasting cylinder door locking mechanism in the guide shaft and the guide shaft hole on the door into H9 / f9 with. Because there is no dust-proof measures, the guide shaft moves frequently, the guide shaft hole on the door body can be easily biased, and there is a gap between the guide shaft and the shaft hole, making it become the main passage for iron pellets and dust to enter the door body. Therefore, the locking mechanism quickly wear parts, increasing the maintenance workload. Sometimes iron pills and dust stuck in the guide shaft and shaft hole, the guide shaft is difficult to move, resulting in failure to lock the drum door, affecting the normal drum work. against
