Description
Technical field:
The present invention relates to a kind of machine components extracting tool, particularly a kind of machine liquid bearing driver-extractor that is used for bearing removal.
Background technology:
In existing technology, the dismounting of bearing all is to adopt mechanical system completely usually, generally is to cooperate with screw mandrel and inside and outside cover, because the screw mandrel carrying is little, so the bearing driver-extractor of this type of Purely mechanical is merely able to be used for the dismounting of small size bearing, and the processing difficulties of screw mandrel.
Summary of the invention:
Technical problem to be solved by this invention is: the carrying of existing bearing driver-extractor is little, can not be used for the dismounting of large size bearing, and is difficult for processing.
The present invention solves the problems of the technologies described above the technical scheme that is adopted to provide a kind of machine liquid bearing driver-extractor, described machine liquid bearing driver-extractor is by interior cover, overcoat, the rectangle nut, the leather bag cover, hex nut, link, cover in the hexagonal screw thread, lever, lever bracket, valve piston, connecting plate, the oil return screw, oil cylinder, piston rod and top formation, be set in described in the work nest of described rectangle nut, the shape of cover can be hollow cuboid in described, cover can symmetry separate along axis direction in described, the arranged outside of cover has overcoat in described, the shape of described overcoat can be hollow cuboid, the outer surface of the inner surface of described overcoat and described interior cover is in contact with one another, one end of described oil cylinder is arranged in the central through hole of described rectangle nut, the other end of described oil cylinder stretches in the described interior cover, can fix by screw thread between described oil cylinder and the described rectangle nut, be provided with piston rod in the described oil cylinder, the external part of described piston rod is provided with top, be coupled to each other between the described top and described piston rod, concrete connected mode can connect for welding, one end of described leather bag cover and the stiff end of described oil cylinder are coupled to each other, the other end of described leather bag cover and described link are coupled to each other, described leather bag cover is provided with the oil return screw, between described leather bag cover and described link, be provided with hex nut, described link interconnects by connecting plate and lever bracket, between described link and described lever bracket, be provided with in the hexagonal screw thread and overlap, be provided with valve piston in the cover in the described hexagonal screw thread, described valve piston and described lever bracket are coupled to each other, concrete connecting mode can connect for pin, described lever bracket is provided with lever, axially axially vertical mutually with described valve piston of described lever, described interior overlapping, overcoat, top, piston rod, oil cylinder, the rectangle nut, the leather bag cover, hex nut, the axis of cover and valve piston overlaps in the hexagonal screw thread.
The present invention and prior art contrast, because used machine liquid bearing driver-extractor, can realize the dismounting to all model bearings, and handling ease is easy to use simultaneously.
