我国现行装配工艺中，对高精度过盈配合大型零件的装配方法是①热装、②冷装、③压装。这些装配方法效率低，精度差．不但不易保证机器装配精度，而且容易破坏零件自身的形状、位置精度和机器的再装精度。采用液压工艺装备进行装配．提高了装配效率，保证了装配、拆卸精度，取 China's current assembly process, the assembly of large parts with high precision interference fit method is ① hot, ② cold, ③ press fit. These assembly methods are inefficient and poor in precision. Not only difficult to ensure the accuracy of the machine assembly, but also easily destroy the shape of the parts themselves, the location accuracy and reloading accuracy of the machine. Hydraulic technology and equipment for assembly. Improve the assembly efficiency, ensure assembly, disassembly precision, take
