Abstract
An auxiliary tool for press fitting of a conical gasket comprises a guiding sleeve, wherein a through hole is formed inside the guiding sleeve, presser feet which are symmetrically distributed relative to a central shaft are arranged at one end, close to an oil pump gear, of the guiding sleeve, the inner diameter of the mutually symmetrical presser feet is the same with the inner diameter of the through hole of the guiding sleeve, the outer diameter of the mutually symmetrical presser feet is the same with the outer diameter of the guiding sleeve, and the inner diameter of the mutually symmetrical presser feet is greater than the outer diameter of a check ring. The auxiliary tool for the press fitting of the conical gasket can rapidly press the conical gasket, improves assembling production efficiency of the check ring, is accurate in assembly of the check ring, enables an oil pump of an engine to play a normal oil pumping function, ensures good operation of the engine, and is simple in structure and low in cost.
Description
Technical field
The utility model relates to press-fiting of the upper conical packing ring of engine, relates in particular to the accessory that press-fits of taper washer on a kind of engine oil pump.
Background technology
Lubricating oil pump is an important spare part in the engine lubrication cooling system, and its structure is made of parts such as lubricating oil pump body, rotor, oil pump gear, oil pump shafts.During assembling oil pump shaft is contained on the oil pump body, oil pump body links into an integrated entity by trundle and oil pump shaft, then gear is contained on the oil pump shaft, by another trundle oil pump shaft is connected diametrically with oil pump gear.In order to guarantee that gear is seated in the axial direction, steady during the engagement running, do not jolt, on the gear taper washer can be installed, back-up ring is installed on taper washer again, back-up ring is contained in the circlip groove of oil pump shaft, and gear is fixed on the oil pump shaft.In order to guarantee that assembling backgear does not have axial float, taper washer is axially having certain compression when assembling, back-up ring just can be seated, and the method that is adopted when assembling back-up ring at present is, two spurs with the back-up ring opening part are stuck on the circlip groove of oil pump shaft earlier, with pliers back-up ring is sticked into circlip groove again, back-up ring produces axial compressive force in sticking into the process of circlip groove, this power will be greatly to making taper washer produce distortion, back-up ring can be contained in the circlip groove of oil pump shaft, and only the strength by hand that taper washer is deformed is very difficult, and the assembling mode has a strong impact on manufacturing schedule, also may cause back-up ring really not to be installed in the circlip groove, in the process of using, cause to come off, influence the normal engaged of oil pump gear, thereby cause the pump functional oil forfeiture of lubricating oil pump, the complete machine lubricating system was lost efficacy, cause engine to damage.
The utility model content
Technical problem to be solved in the utility model is: a kind of easy accessory that press-fits taper washer is provided, motion by accessory applies axial pressing force to taper washer, back-up ring accurately is installed in the oil pump shaft circlip groove, thereby make the engine oil pump pump functional oil of bringing into normal play, guarantee the engine good operation.
In order to solve the technical problem in the assembling, the utility model has been taked following scheme:
A kind of taper washer press-fits accessory, comprise fairlead, described fairlead inside offers through hole, fairlead is provided with the presser feet that is symmetrically distributed with respect to central shaft near an end of oil pump gear, the internal diameter of presser feet is identical with fairlead through hole internal diameter symmetrically, external diameter is identical with the outside dimension of fairlead, and the internal diameter of presser feet is greater than the back-up ring external diameter symmetrically.
Described fairlead other end external diameter adopts the Morse's taper face, cooperates with upright drill.
The beneficial effect that the utility model can reach is: owing to adopt taper washer to press-fit accessory, can press-fit taper washer fast, improve back-up ring Assembling Production efficient, the back-up ring assembling is accurately put in place, and make the engine oil pump pump functional oil of bringing into normal play, guarantee the engine good operation, and simple in structure, with low cost.

The specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
During concrete enforcement, as Fig. 1-shown in Figure 4, when taper washer press-fits the accessory use, Morse's taper face 1c with fairlead 1 is connected with upright drill earlier, trundle 7 is passed the hole that oil pump shaft 3 footpaths make progress, again oil pump gear 5 is contained on the oil pump shaft 3, simultaneously the drive pin slot 5a on the oil pump gear 5 is stuck on the trundle 7, taper washer 4 is installed on plane on the oil pump gear 5 then, the parts that assemble are placed on press-fit under the accessory, rotate the vertical drill handle, press-fiting accessory moves down, adjust the position of parts, 1 two presser feet 1b of fairlead are pressed on the taper washer 4 symmetrically, taper washer 4 is subjected to downward axial pressing force, produce axial crushing deformation, up to exposing oil pump shaft circlip groove 2a, push in the oil pump shaft circlip groove 2a from the dead ahead with back-up ring 3, unclamp the vertical drill handle, press-fit accessory and leave taper washer 4, taper washer 4 is because compression produces a reverse screen resilience, back-up ring 3 is pressed in the oil pump shaft circlip groove 2a tightly, because oil pump gear 5 lower surfaces inwardly are provided with oil pump gear drive pin slot 5a, be stuck in firmly on the trundle 7 by drive pin slot 5a during oil pump gear 5 assemblings, and the upper end is fixing by taper washer 4 and back-up ring 3, make oil pump gear 5 axial direction can not occur play and about jolt, guaranteed oil pump gear 5 runnings steadily.
Adopt above-mentioned press-fit accessory after, can press-fit taper washer fast, improve the efficiency of assembling of back-up ring, back-up ring can accurately be installed in the circlip groove, thereby make oil pump gear energy normal engaged, lubricating oil pump pump functional oil is able to normal performance, guarantee the good operation of engine, prolong the life-span of engine, and simple in structure, with low cost.
