我厂是液压件生产厂。油缸车间的H057四米外圆磨床,主要用于磨削两米和两米以上的活塞杆。自1980年安装以来,磨削性能基本能满足工艺要求,表面粗糙度在R_α0.63左右。但至1984年底,就出现了纵向工作台往复运动产生爬行,低速时尤为严重。以致磨削工件表面粗糙度不符合要求,并有螺旋线状波纹。引起工作台爬行的主要原因是运动件摩擦副间力的不均匀。为此,首先检查了纵向工作台驱动油缸活塞杆的直线度,导轨与活塞杆的平行度,油缸两端支架和工作台刚性连接处密封的松紧程度,油缸内孔有无拉毛和活塞两端螺母的松紧程度,都未发现异常。
Our factory is a hydraulic parts factory. Cylinder workshop H057 four meters cylindrical grinder, mainly for grinding two meters and two meters above the piston rod. Since the installation in 1980, the grinding performance can basically meet the technical requirements, the surface roughness of R_α0.63 or so. However, by the end of 1984, there was a crawling of the longitudinal workbench reciprocating motion, which was especially serious at low speed. As a result, the surface roughness of the grinding workpiece does not meet the requirements, and helical linear corrugation. Caused by the main reason for crawling table is moving parts friction between the uneven force. To this end, first check the longitudinal workbench drive cylinder rod straightness, rail and piston rod parallelism, both ends of the cylinder bracket and workbench rigid connection at the tightness of the seal, the cylinder bore with or without both ends of the piston Nut tightness, no abnormalities were found.
