M7271立式磨床的液压筒如图1所示,由于某些原因,在缸体内壁上有毛刺,毛刺高度约0.1~0.2mm.缸体材料为45号无缝钢管.要去除缸体内壁的毛刺,如采用鏜削的方法,厂内没有这样长的加工设备,请外单位协作,所需时间较长.该机床系关键设备,长时期的停工要影响厂生产任务的完成.经讨论,我们采用以下的方法进行修复.一、结构图2为修复缸体的设备简图。先以两块支座1将缸体支承起来;放在床身较长的6M龙门刨床台面上,
M7271 vertical grinder hydraulic cylinder shown in Figure 1, for some reason, burr on the cylinder wall, burr height of about 0.1 ~ 0.2mm. Cylinder material for the 45 seamless steel pipe to remove the inner wall of the cylinder Burr, such as the use of boring method, the factory does not have such a long processing equipment, please units outside the collaboration, the longer the time required. The key equipment of the machine tool, a long period of downtime to affect the completion of plant production tasks. After discussion, We use the following method to repair. First, the structure Figure 2 is a schematic view of the repair equipment cylinder. The first two bearings to support the cylinder 1; on the bed longer 6M planer table,
