Description
Technical Field
The utility model relates to a technical field of hydro-cylinder assembly, concretely relates to in a hydro-cylinder with draw a seat to aligning adjustment mechanism.
Background
The oil cylinder is a hydraulic actuating element which does linear reciprocating motion or swinging motion, the coaxiality of the piston rod and the pull seat is required to be ensured in the oil cylinder assembling process, otherwise, the oil cylinder is subjected to unbalance loading in the working process, and the service life of the oil cylinder is influenced.
The traditional scheme is that the length of a repairing shaft sleeve is used for adjusting the coaxiality of a piston rod and a pull seat in the assembling process, repeated repairing and adjusting are needed, conditions are not generally met on the site of a construction site, the operation is complex, and the efficiency is low.
SUMMERY OF THE UTILITY MODEL
In view of this, the utility model provides an hydro-cylinder with draw seat to heart guiding mechanism, adjustment process is simple easily to be realized, efficient.
The utility model adopts the following technical scheme:
a centering adjusting mechanism for an oil cylinder and a pull seat comprises an adjusting gland, an adjusting screw, a rotating shaft, a shaft sleeve, a bearing assembly and a fixing assembly; the peripheral components are a piston rod and a pull seat;
the piston rod is arranged between the two lug plates of the pull seat through the rotating shaft, and the axis of the piston rod is vertical to the axis of the rotating shaft; the piston rod is fixedly connected with a bearing assembly, and the bearing assembly is in transition fit with the rotating shaft; meanwhile, one end of the rotating shaft is fixedly connected with an ear plate of the pull seat through a fixing component, the shaft sleeve is pressed on the end face of the bearing component, the other end of the rotating shaft is sleeved by an adjusting gland, the adjusting gland is fixedly connected with the end face of the rotating shaft through an adjusting screw, and the adjusting gland presses the other shaft sleeve on the end face of the other end of the bearing component;
the distance between the axis of the piston rod and the symmetrical center line of the pull seat is changed by adjusting the length of the adjusting screw screwed into the rotating shaft.
Further, the bearing assembly comprises a bearing gland, a joint bearing and a mounting screw;
the joint bearing is packaged by bearing pressing covers at two ends, and the bearing pressing covers are fixedly connected with the piston rod through mounting screws.
Furthermore, the fixing assembly comprises a shaft end baffle and a locking screw;
the shaft end baffle is arranged in the limiting groove of the rotating shaft and is fixedly connected with the pull seat through a locking screw.
Has the advantages that:
the utility model discloses a length of adjustment adjusting screw in pivot makes the axle sleeve drive bearing assembly and pivot and takes place relative movement, because bearing assembly links firmly with the piston rod, the pivot with draw the seat to link firmly, adjusted the piston rod axis from this and drawn the distance between the seat symmetry center line, guarantee the axiality, the adjustment process is simple easily to be realized, efficient.
