Description
Technical field
The present invention relates to a kind of installation shaft that is used on the bigger workpiece of diameter with the instrument of elastic wire back-up ring.
Background technology
When in daily production process, assembling the elastic wire back-up ring, generally need be contained in than on the also big workpiece of its internal diameter.Present main installation methods is to use screwdriver to pry open back-up ring, is pressed into back-up ring on the workpiece of back-up ring to be installed with other instruments simultaneously.This assembly method bothers very much; And often scratch the surface of elastic wire back-up ring or workpiece; Its efficiency of assembling is low; Labour intensity is big, particularly in the assembling often the coping screw cutter skid and the elastic wire back-up ring occurs and jump and fly to scratch human body or drop and in the equipment that other is turning round, cause safety problem.
Published in 1989 " mechanic. cold working " the 05th interim a kind of self-control elastic spring erecting tools disclosed; This elastic spring erecting tools is made up of the pushing sleeve that a cone stem and internal diameter are slightly larger than back-up ring workpiece external diameter to be installed, and the interior hole depth of pushing sleeve adds back-up ring to be installed being advisable apart from sum to circlip groove to be slightly larger than the stem height.During use; Earlier the cone stem is inserted in the workpiece hole of sweeping circle to be installed, again with the elastic wire shield ring sleeve on stem, withstand the elastic wire back-up ring firmly to pressing down with pushing sleeve at last; Elastic wire back-up ring spreading gradually under the effect of cone stem; Just in time the workpiece external diameter with back-up ring to be installed is suitable for its diameter when the elastic wire back-up ring is pushed to the big end of stem, continues to exert pressure this moment just to be installed to the elastic wire back-up ring end of workpiece, then the elastic wire back-up ring is pushed in the circlip groove.If but have the step of diameter on the workpiece of back-up ring to be installed greater than its end; And when circlip groove is arranged on this step; This elastic spring erecting tools just only can be installed in back-up ring the end of workpiece and can't back-up ring be installed in the circlip groove on the step, and this is former so to need to use mode of screwdriver sled that back-up ring is in place.Thereby the scope of application that should make the elastic spring erecting tools by oneself is narrower, can not be applicable to comparatively complicated situation of workpiece outer surface structure.
Summary of the invention
Task of the present invention is over against above-mentioned defective, provide on a kind of workpiece that goes for back-up ring to be installed to have the step of diameter greater than its end, and circlip groove is arranged on the elastic wire back-up ring assembly tooling on this step.
For realizing this above-mentioned purpose; The technical scheme that the present invention takes is: the assembly tooling of a kind of elastic wire back-up ring; This assembly tooling is mainly pegged graft to cooperate the tapering transition minor axis that is used for the spreading back-up ring and cooperate with the coaxial roof pressure of transition minor axis with an end by the interstage sleeve that is used for support back-up ring to be installed, an end and interstage sleeve and is used to clamp back-up ring and forms with the pushing sleeve of maintenance back-up ring spreading state; The upper surface that cooperates with the grafting of transition minor axis on the said interstage sleeve is provided with the annular support face that is used for support back-up ring to be installed; The cover bore dia of this interstage sleeve is less than the external diameter of back-up ring to be installed; The end diameter of said tapering transition minor axis is less than the internal diameter of back-up ring to be installed, and its outside diameter is less than or equal to the cover bore dia of interstage sleeve, axially offers the through hole that supplies workpiece to pass on the said pushing sleeve; The roof pressure end periphery of pushing sleeve is provided with the face of cylinder that is used to keep back-up ring spreading state, and the external diameter on this face of cylinder is less than or equal to the outside diameter of transition minor axis.The utility model adopts technique scheme; It is through cooperating elastic wire back-up ring spreading between the pyramidal structure on the transition minor axis and the interstage sleeve; Simultaneously pushing sleeve cooperates the elastic wire shield ring sleeve on the cylindrical of pushing sleeve through the grafting with the transition minor axis, and pushing sleeve utilizes its through hole to be enclosed within directly to move on the workpiece step place that workpiece is provided with circlip groove, then the elastic wire back-up ring is packed in the circlip groove; It is simple in structure; At the workpiece that guarantees not damage elastic wire back-up ring and back-up ring to be installed simultaneously, can be easily load onto the elastic wire back-up ring on the workpiece of step having, not only reduced installer's labour intensity; And improved efficiency of assembling, avoided occurring the elastic wire back-up ring simultaneously and collapsed and open the dangerous situation of hurting sb.'s feelings.
As further improvement, the trepanning hole that is positioned at described interstage sleeve support face place is along offering the taper chamfering, and the outside diameter of taper chamfering is more than or equal to the external diameter of back-up ring to be installed.Adopt this technical scheme, the trepanning hole can be so that anti-Sealing shield ring sideslip be placed in the location of back-up ring to be installed along the taper chamfering of locating.
Further, described tapering transition minor axis is a frusto-conical configuration, and coaxial being installed with extended the guide frame that cooperates with the trepanning grafting of pushing sleeve vertically on the end face of the larger diameter end of this truncated cone.Adopt guide frame to cooperate and to make pushing sleeve and transition minor axis maintenance concentric easily, be convenient to back-up ring and slide on the pushing sleeve, the while sideslip that skids in the time of can also preventing pushing away under the exerting oneself of thrust housing with pushing sleeve.
Further, described guide frame is and the cylinder of the coaxial structure that is fixed with one of truncated cone that this cylindrical external diameter is less than the outside diameter of truncated cone.The cylinder guide frame that employing is wholely set is convenient to make and is manufactured.
Further, the trepanning of said interstage sleeve is a blind hole, and the conical section length of the length of this blind hole and said tapering transition minor axis is suitable.
Further, lean on the circular cone table top that near the periphery roof pressure end, is provided with axial limiting at said pushing sleeve.Adopt this structure can prevent to push away under the transition minor axis and overdo, the back-up ring position is bad to be confirmed.
