FMS-1500-2柔性加工系统抓刀装置的夹紧油缸上的四氟密封环损坏,多次造成停工。经调查国内尚无此规格油封。开始,我们按照国外的密封环尺寸在国内进行加工。因材料解决不了,新密封环安装后,不久就失灵了,经常出现打刀、掉刀故障。经过维修工人和技术人员分析研究,提出了利用国产聚安脂轴用油封替代进口原件油封,并对原夹紧油缸进行改造。改造后的夹紧油缸装上国产聚安脂油封,试用将近1年,效果良好。不仅短期内排除了故障,而且又解决了油封备件的供应问题。 该机床刀架移动的变速压力开关,在使用了5年后被压力击穿,备件已用完,被迫停产。该压力开关体积小,安装位置紧凑,国内同类产品无法替代,而从国外购置,订货周期长。这时,我们立足本厂解决问题,首先,对已经报废的压力开关进行了解剖。这种TYP9054压力开关,是靠一个橡胶薄膜微动完成动作。该薄膜是一次性压制在结构内的,一旦被击穿,整
FMS-1500-2 flexible processing system grasping knife clamping cylinder on the PTFE seal ring damage, causing many downtime. After investigation, there is no such oil seal in China. At the beginning, we processed in China according to the size of the seal ring in foreign countries. Because the material can not be solved, the new seal ring installed soon after failure, often appear hit a knife, a knife fault. After the repair workers and technical personnel analysis and research, put forward the use of domestic polyurethane shaft seal instead of imported original seal, and the original clamping cylinder transformation. After the transformation of the clamping cylinder fitted domestic polyurethane seal, nearly 1 year trial, the effect is good. Not only short-term ruled out the fault, but also solved the supply of oil seal spare parts. The machine tool turret moving speed switch, after 5 years in use pressure breakdown, spare parts have run out, was forced to stop production. The pressure switch is small, compact installation location, similar products can not be replaced, but from abroad, ordering long period. At this time, we are based on the factory to solve the problem, first of all, has been scrapped the pressure switch anatomy. This type of pressure switch TYP9054, is a complete action by a thin rubber film. The film is a one-time suppression in the structure, once the breakdown, the whole
