目前,国内一些液压机械主机厂,选用了国家标准GB5625～5653—85中的两种可调向端管接头,国外进口的液压机械上也有类似的接头。但这种接头规格多、用量少,很多生产、维修厂家缺乏专用的装配设备,我厂为组装这种接头设计了一套简易工装,使用证明完全能达到锁紧螺母垫圈(以下简称垫圈)的装配技术要求。图1为扩口式可调向端管接头,在使用时装配示意图。从图1中可看出,垫圈装配后必须保证:垫圈与接头的圆柱面配合紧密,按设
At present, some domestic hydraulic machinery main engine plants have used two adjustable end-to-end fittings in the national standard GB5625 to 5653-85. There are also similar joints on imported hydraulic machinery. However, this type of connector has many specifications and usage, and many production and maintenance manufacturers lack special assembly equipment. Our factory has designed a set of simple tooling for the assembly of this joint, and the use proves that it can completely reach the lock nut washer (hereinafter referred to as the washer). Assembly technology requirements. Figure 1 shows the flared adjustable end fittings. As can be seen from Figure 1, after the gasket is assembled, it must be ensured that the gasket fits tightly with the cylindrical surface of the joint.
