工程机械液压缸筒因内壁螺旋加工问题,造成报废的比率很大。为此,我厂对缸筒螺旋进行了观察、测定、分析。现介绍如下。一、螺旋形状缸筒加工后,目测有均匀螺旋线,用手贴在缸筒内壁上沿缸筒轴向移动,有节奏分明的凹凸不平感觉。把缸筒沿轴向取其一段,再沿周向剖成若干片,取其一片用样板尺贴紧缸筒
Due to the spiral machining of the inner wall, the hydraulic cylinder of the construction machinery has caused a great deal of scrap. For this purpose, our factory observed, measured, and analyzed the spiral cylinder. The introduction is as follows. First, spiral shape cylinder processing, visually have a uniform spiral, hand attached to the cylinder wall along the axial movement of the cylinder, there is a clear rhythm uneven feeling. Take a section of the cylinder in the axial direction, and then cut it into several pieces in the circumferential direction. Take one piece of the cylinder tightly with the cylinder tube.
