Variable gauge fixed bearing press-fitting machine

A fixed stand column is arranged at one end of a supporting frame, an auxiliary stand column is arranged at the other end of the supporting frame, a movable stand column is arranged on the supporting frame in a sliding mode in the horizontal direction, a first press-fitting cylinder is installed on the movable stand column, and a second press-fitting cylinder is installed on the auxiliary stand column. A lifting platform assembly is arranged in the middle of the supporting frame. The railway bearing automatic press-fitting machine has the beneficial effects that the distance between the first press-fitting cylinder and the second press-fitting cylinder can be adjusted through the movable stand column arranged on the supporting frame, and therefore the railway bearing automatic press-fitting machine compatible with a narrow gauge, a standard gauge and a wide gauge is formed; the blank that bearing press-fitting machines suitable for and compatible with different sizes of railway wheel set wide gauges, narrow g
