a piston rod head end of the first oil cylinder and a piston rod head end of the second oil cylinder are both provided with a circular top pressing block in a fastening mode through bolts;
the piston rod of the first oil cylinder can be pressed rightwards after extending out, and the piston rod of the second oil cylinder can be pressed leftwards after extending out.
The U-shaped groove of U-shaped locating plate is used for placing the rotor, and first hydro-cylinder and second hydro-cylinder all adopt the path hydro-cylinder, and the equipment is realized through the roof pressure of first hydro-cylinder and second hydro-cylinder to the rotor bearing.
The utility model not only can avoid large workpiece scattering caused by unstable pressure value of the original vertical press-mounting machine, but also can reduce the phenomena of rework, scrapping and the like of shaft out-of-tolerance caused by large stress of the original vertical press-mounting machine.
The utility model can effectively reduce stress so as to ensure that the deformation amount of the product is controlled within the variation amount range of the process requirement, thereby effectively preventing reworking and scrapping caused by the deformation of the product shaft.
The utility model is suitable for rotor press-mounting bearings of all Italian motors, motors with the number of 11KW and above and motors with the number of 15HP and above.
The utility model has the advantages of novel structure, higher working efficiency, lower processing cost and stronger practicability.
