Abstract
The utility model discloses an adaptive roller shifting cylinder connecting device. Hemispherical concave surfaces are respectively arranged at the centers of matching surfaces of mutually matched upper and lower side retaining rings, and a small-end through hole of each hemispherical concave surface is matched with a piston rod of a roller shifting cylinder; mutually matched concave and convex platforms are arranged on the matching surfaces of the upper and lower side retaining rings for positioning, and the upper and lower side retaining rings are fixedly connected together through connecting bolts; the hemispherical concave surfaces of the upper and lower side retaining rings form a spherical cavity, and a spherical nut is arranged on the piston rod through threads and is arranged in the spherical cavity formed by the upper and lower side retaining rings; and an annular groove formed by the peripheries of the upper and lower side retaining rings is matched with a rack connecting convex platform. According to the adaptive roller shifting cylinder connecting device provided by the utility model can automatically follow up and adjust the deviation tension or deviation compression force which is borne by the connecting bolt of the roller shifting cylinder and a mill stand and is formed by position deviation caused by wear and tear, so that the connecting nut is unthreaded, the wear of an oil cylinder guide sleeve and a sealing component is reduced, the rupture of the root of the piston rod is prevented, and the service life of the device is prolonged.
Description
Technical field
The utility model belongs to the jockey of rolled steel plate hoop mill work roll shifting cylinder and milling train, particularly self-adapting type roll shifting cylinder jockey.
Background technology
In the hot continuous rolling technology; Be used for connecting attaching nut between roll shifting cylinder and the rolling-mill housing because of structure in its special hand; Caused with in the periodic change procedure of production process; After the certain degree of the wear liner of the bound fraction of the base of roll shifting cylinder and milling train, uncontrollable running, oil cylinder fairlead are are sharply worn and torn, a series of disabler failure problems such as potted component lost efficacy unusually, the fracture of piston rod root to cause the attaching nut of roll shifting cylinder to happen suddenly in the increasing process of the alternating bending stress that roll shifting cylinder attaching nut bears.
Summary of the invention
The purpose of the utility model is to provide a kind of self-adapting type roll shifting cylinder jockey; Can follow automatically and regulate owing to wearing and tearing produce position deviation and add the deflection stretching that roll shifting cylinder and rolling-mill housing attaching nut are born that forms or be partial to compression stress; Make the attaching nut of roll shifting cylinder and rolling-mill housing that running not take place; Reduce the wearing and tearing of oil cylinder fairlead and potted component, prevent the fracture of piston rod root, prolong service life of equipment.
The purpose of the utility model is achieved in that a kind of self-adapting type roll shifting cylinder jockey; Comprise rolling-mill housing and working roll roll shifting cylinder piston rod; The center of upper and lower its mating surface of side back-up ring that cooperatively interacts is being provided with symmetrical hemisphere concave surface respectively; The small end through hole of hemisphere concave surface matches with the roll shifting cylinder piston rod, and concavo-convex that cooperatively interacts through setting on the mating surface of upper and lower side back-up ring positions, and through connecting bolt upper and lower side back-up ring is fixed together; The hemisphere concave surface of upper and lower side back-up ring constitutes the spheroid cavity; Through screw thread the spheroid nut is installed on the piston rod, the spheroid nut cooperates in the spheroid cavity that is installed in upper and lower side back-up ring formation, and the annular groove that constitutes between the periphery of upper and lower side back-up ring is connected boss with frame and matches.
When the utility model device uses; Be installed in spheroid nut on the threaded piston rod plays the spheroid nut through two spheroid nut anti-looseness screws locking effect; The spheroid nut is connected between inboard back-up ring and the outside back-up ring through the back-up ring attaching nut between inboard back-up ring and the outside back-up ring, and inboard back-up ring also has been connected frame with inboard back-up ring with outside back-up ring with outside back-up ring and has been connected on the projection when being connected the spheroid nut.When threaded piston cylinder in the space along being parallel to himself axis and when its axis is done a certain amount of position of arbitrary direction and moved; Spheroid attaching nut on it follows threaded piston rod together and does accompany movement through driving inboard back-up ring and outside back-up ring, and the annular groove that constitutes between the periphery because of inboard back-up ring and outside back-up ring is connected with frame between the projection through the corresponding gap that has certain accompany movement between connecting between the back-up ring attaching nut.The concave surface just that inboard back-up ring and outside back-up ring is inner because of the back-up ring attaching nut between inboard back-up ring and the outside back-up ring coincide with the spheroid nut is accurate mutually; Make a certain amount of bending force around the spheroid nut centre of sphere in arbitrary direction when threaded piston rod and do the time spent; The spheroid nut all can be done relative following with respect to interior contiguous block and outer contiguous block and rotatablely move, and the deflection of having brought when just directly having avoided between threaded piston rod and the nut power by bending stretches and is partial to compression stress.
The utility model has been realized following automatically and regulate owing to wearing and tearing produce position deviation and add the deflection stretching that roll shifting cylinder and rolling-mill housing attaching nut are born that forms or is partial to compression stress; Make the attaching nut of roll shifting cylinder and rolling-mill housing that running not take place; The wearing and tearing of oil cylinder fairlead and potted component have been reduced; Prevent the fracture of piston rod root, prolonged service life of equipment.
