我 公司F型装载机工作装置的动臂各铰接孔内安装了由45钢制成的钢套 ,装配时需要将钢套压入到已加工好的孔内。由于动臂的尺寸太大 ,无法在油压机的工作台上将钢套压入 ,采用铁锤敲击的方法进行装配。用该方法装配容易使动臂变形 ,破坏了各孔之间的形位精度 ,不能保证装配质量
The F-loader working device of our company has the steel sleeve made of 45 steel installed in each hinge hole of the boom, and the steel sleeve needs to be pressed into the machined hole during assembly. Due to the size of the boom is too large, the steel sleeve can not be pressed into the workbench of the hydraulic press, and the hammer is used to assemble it. Assembled with this method is easy to deformation of the boom, destroyed the shape accuracy between the holes, can not guarantee the assembly quality
