Pressing fit machine for rolling bearing pedestal

Abstract

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.

Description

technical field [0001] The invention relates to a pressure assembling machine, in particular to a pressure assembling machine for loading a rolling bearing into a bearing seat. Background technique [0002] A large number of rolling bearings are used to support the rotating shaft in the project. Since the inner ring of the rolling bearing and the shaft, and the outer ring of the rolling bearing and the bearing seat are often used for interference fit, for the bearing connection of small size, the bearing is usually driven in manually with a hammer, which will cause assembly problems. When the force is uneven in the circumferential direction, the assembly is difficult, the time is long, and it will hit the bearing surface, which will damage the bearing and other parts in severe cases. [0003] For this reason, someone has studied bearing installation equipment specifically for this problem, such as the schemes published in Chinese patents: CN201534273U and CN202367420U, in wh...

Problems solved by technology

[0002] A large number of rolling bearings are used to support the rotating shaft in the project. Since the inner ring of the rolling bearing and the shaft, the outer ring of the rolling bearing and the bearing seat often adopt an interference fit, for the bearing connection of a small size, the bearing is usually driven in manually with a hammer, which will cause assembly failure. When the force is uneven in the circumferential direction, the assembly is difficult, the time is long, and it will hit the bearing surface, which will damage the bearing and other parts in severe cases.

[0003] For this reason, someone has studied bearing installation equipment specifically for this problem, such as the schemes published in Chinese patents: CN201534273U and CN202367420U, in which two kinds of bearing press-fitting machines are announced, and an intermediate spindle fixing platform is required in these two kinds of press-fitting machines , in the actual operation process, because the coaxiality of the main shaft and the bearings at both ends is difficult to guarantee, the installation accuracy is reduced

The reason is that the positioning reference of the main shaft is on the main shaft fixed platform, and it is difficult to adjust the platform to make the three coaxial
