Description

A kind of axial location elastic spring press mounting tool
Technical field
The utility model belongs to parts mounting technology field, relates generally to a kind of axial location elastic spring press mounting tool, can be applied to that sleeve and axial workpiece cooperatively interact and need the occasion of axial location during transferring power.
Background technology
When axle is with a seat working surface while directly contacting, because running up of axle can cause wearing and tearing between axle and seat, be to save the cost of changing axle or seat, conventionally presently interiorly with interference fit, be pressed into lining, axle is directly contacted, resleeve more after wearing and tearing with lining.Although be interference fit between axle and lining, often there is the situation of axial float between the two, need to install back-up ring and carry out axial location.When back-up ring is arranged on the interference fit face between axle and lining, install very difficult.Just more difficult realization of the installation of back-up ring between gear and lining, not only lining and gear are interference fit, and back-up ring should be stuck in bore wall circlip groove and excircle of bushing circlip groove.For completing the installation of back-up ring between gear and lining, adopt at present following two kinds of methods: method 1: first back-up ring is put in the circlip groove of bore; Next is pressed into bore wall circlip groove one side with the conic sleeve that outside diameter is slightly larger than bore; Again cooled with liquid nitrogen back bush is pressed into from opposite side, conic sleeve is extruded and made back-up ring fall into excircle of bushing circlip groove.It is wayward that the method sleeve is pressed into the dynamics of bore, dynamics is little cannot strut back-up ring, great efforts meeting causes sleeve being extruded to lining locking, when dynamics is suitable, also need a people holding up sleeve, convergent force and sleeve self gravitation because of back-up ring while preventing from not packing lining into cause sleeve to squeeze.And the method often occurs that sleeve extrudes rear elastic spring and do not fall the situation on excircle of bushing, makes to press-fit failure.Method 2: put into cooled with liquid nitrogen after back-up ring being installed in the circlip groove of excircle of bushing, gear is fixed, more cooled lining and back-up ring are pressed into bore in the lump, until retainer-ring press mounting is in bore wall circlip groove.When the method press-fits, often there is deviating from the phenomenon of circlip groove in the back-up ring in lining circlip groove, causes press-fiting failure, and when the magnitude of interference is larger, easily make the scratch of gear inwall.Above two kinds of methods press-fit qualification rate and efficiency is all very low.
Utility model content

The utility model adopts following technical proposals to complete its invention task:
A kind of axial location elastic spring press mounting tool, described press mounting tool includes supporter I, supporter II and screw rod; Described supporter I and supporter II are formed by sleeve cutting, described sleeve is the Step Shaft with cylindrical cavity, Step Shaft small end outside diameter is less than the interior circular diameter of elastic spring free state, Step Shaft small end length of bench is slightly larger than the distance of bore wall circlip groove to gear face, the interior circular diameter of Step Shaft is less than the interior circular diameter of lining, and the large end outside diameter of Step Shaft is than more than the large 10mm of bore diameter; At the large end of Step Shaft, be processed with a unthreaded hole and a screwed hole, described unthreaded hole and screwed hole are same center line crossing with sleeve centerline; Sleeve cut surface passes through sleeve centerline the center line perpendicular to unthreaded hole and screwed hole; Described unthreaded hole is positioned in supporter I, and described screwed hole is positioned in supporter II; Described screw front end is one section of step optical axis, shaft diameter is less than the unthreaded hole diameter in supporter I, described screw rod other end cross section is regular polygon, described screw rod middle part is threaded into the screwed hole in supporter II, the optical axis of screw front end is inserted in the unthreaded hole of supporter I, described supporter I is rotation by screw rod by jack-up upwards, the structure that supporter II is opened gradually relatively.
Utilize above-mentioned press mounting tool to press-fit the method for axial location elastic spring, the concrete steps of described pressing method are:
(1) first lining is put into the cooling 5-10 minute of liquid nitrogen of subzero 190 ℃;
(2) elastic spring is put into bore wall circlip groove, gear is placed into corresponding position and makes gear centre line is level, and gear is fixed;
(3) make the Step Shaft small end of described press mounting tool, the one end along bore wall with circlip groove enters in bore, and enter in the elastic spring endoporus that is placed into bore wall circlip groove, and the lower end that makes supporter II is adjacent to bore wall lower end, now elastic spring lower end enters in bore wall circlip groove;
(4) use torque wrench rotary screw, along with the screw-in of screw rod, the front end step of screw rod is by upwards jack-up of supporter I, make supporter I and supporter II relative opening gradually, until the periphery of supporter I and supporter II contacts with bore wall, elastic spring is all strutted in bore wall circlip groove;
(5) take out cooled lining, excircle of bushing is had to one end of circlip groove from being pressed into away from bore wall circlip groove one end, lining continues to be pressed into after contacting with described press mounting tool, until press mounting tool is extruded, and elastic spring is dropped in the cylindrical circlip groove of lining and the circlip groove of bore wall.
The axial location the utility model proposes elastic spring press mounting tool, can meet press-fiting of elastic spring between the lining of the large magnitude of interference and gear mating surface; Press mounting tool is simple in structure, press-fits efficiency high, and qualification rate is high.The utility model is not only applicable to press-fiting of elastic spring in gear lining, can be applied to cooperatively interact transferring power and need the occasion of axial location of sleeve and axial workpiece yet.
