The invention provides a pressing fit
machine for a rolling bearing pedestal. A support platform consists of a left support base, a right support base and a pressing fit table, and the heights of the left support base and the right support base can be respectively adjusted, so that the levelness of the pressing fit table can be guaranteed; and the right support base is fixedly provided with a
hydraulic cylinder, a
piston rod of the
hydraulic cylinder horizontally and leftwards extends, the front end of the
piston rod is fixedly provided with a
piston rod connecting piece, the left end of the
piston rod connecting piece is provided with a first bearing installing part, and the left support base is a main shaft installing part. When the pressing fit
machine is used, a left-side bearing and a main shaft workpiece are directly arranged on a main shaft fixed guide sleeve, the left-side bearing and the main shaft workpiece are coaxial with each other, and the pressing fit
machine can be better positioned, is free from adjustment, and can be used only by adjusting the coaxial relationship between a right-end bearing and the main shaft, so that one adjustment can be reduced, and the
assembly efficiency and precision can be improved. Meanwhile, the bearing in the device is directly clamped into a bearing guide
lantern ring, so that the pressing fit machine can be conveniently and quickly used.
