液压设备的橡胶油管与接头的连接,采用带有特殊螺纹的螺母,把橡胶油管和接头紧固。为连按牢固,故橡胶管外径尺寸大于螺母的螺纹公称直径,并且橡胶油管内设有多层编织的钢丝。所以,在更换新橡胶油管时比较困难。我们制作了结构简单的引导工具,可使橡胶油管方便地与接头螺母连接好。简易工具由对开螺母1、外套2和两对对开衬套3等组成。使 Hydraulic equipment, rubber tubing and fittings connection, the use of a special thread nut, the rubber tubing and fittings fastening. In order to press firmly, so the outer diameter of the rubber tube diameter greater than the nominal diameter of the nut thread, and the rubber tubing with a multi-layer woven steel wire. Therefore, it is more difficult to replace the new rubber tubing. We made a simple structure of the guide tool, rubber hose can easily connect with the nut. Simple tools from the nut 1, 2 and two pairs of split outer sleeve 3 and other components. Make
