When the graphite bearing is naturally placed and solidified, the situation of infirm adhesion may exist, and a gap may exist between the graphite bearing and the inner joint end surface of the bushing, so that the bonding quality of the graphite bearing and the bushing is improved, and a bearing combined assembly fixture is required to be designed.
Disclosure of Invention
The utility model provides a bearing combination assembly fixture which provides clamping force for bearing combination bonding and solidification, so that the graphite bearing is tightly attached to the inner bonding end surface of a bushing, and the bonding quality is improved.
The technical scheme of the utility model is as follows: a bearing combination assembly fixture comprises a base, a cover plate, a screw, a gasket and a nut. The base is a discoid revolving body, a cylindrical bulge is arranged in the middle of the base and is drilled with a through hole, and a bearing assembly and a cover plate are arranged on the base; the cover plate is disc-shaped, a two-stage stepped groove is formed in the middle of the bottom surface, and a hole is formed in the center; the screw rod passes through the base, the bearing combination and the cover plate; the gasket is fixed on the cover plate; the nut is connected with the screw rod to fasten the base, the bearing combination and the cover plate.
In the utility model, the screw comprises a head cube and a rod-shaped structure, and the upper end of the rod-shaped structure is provided with external threads.
In the utility model, the base and the cover plate are used for clamping the bearing combination and transmitting the pressing force; the screw rod and the nut are used for fastening the base, the bearing combination and the cover plate to provide clamping force.
The utility model has the beneficial effects that: the reliable assembly fixture is simple in structure and convenient to assemble and disassemble for assembling the bearing combination. When the bearing combination is bonded and solidified, axial opposite pressing forces are provided on the end faces of the two sides of the bearing combination, so that the graphite bearing is tightly attached to the inner bonding end face of the bushing, gaps are effectively eliminated, and bonding quality is ensured.
