In a preferred embodiment of the present utility model, described positioning boss and positive stop lug boss are cylindrical boss, and their external diameter is all less than the internal diameter of described bearing slightly, and their height sum is less than or equal to the height of described bearing.
In a preferred embodiment of the present utility model, described guide-localization mould is the external diameter that cylindrical structural and its external diameter equal described bearing inner race, the end face that described guide-localization mould contacts with described positive stop lug boss forms a step surface, when the positive stop lug boss of described guide-localization mould inserts in described bearing, described guide-localization mould is taken and is held on the end face of described bearing by described step surface.
In a preferred embodiment of the present utility model, described pressing mold is the cylinder end of with, the internal diameter of described pressing mold is greater than the external diameter of described guide-localization mould slightly, described pressing mould sleeve is on described guide-localization mould, the end face of the relatively described positive stop lug boss of described guide-localization mould just conflict described pressing mold cylinder the end inwall on, and described pressing mold cylinder an end face just flush with the step surface of described guide-localization mould.
In a preferred embodiment of the present utility model, the center of described pressing mold base, guide-localization mould and pressing mold arranges respectively coaxial through hole.
In a preferred embodiment of the present utility model, the end face of described positioning boss, the end face of described positive stop lug boss and described guide-localization mould are all ground into inclined-plane away from the edge of the end face of that one end of described positive stop lug boss.
Owing to having adopted technological scheme as above, the beneficial effects of the utility model are: the mould that adopts pressing mold base, guide-localization mould and pressing mold to combine is pressed into oil sealing dust cover in the groove of bearing, ensure the sealing effect of bearing, improve the working life of bearing, the bearing being assembled by combined mould, constant product quality, assembling is quick.
Brief description of the drawings
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is structural representation of the present utility model.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach object and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
Referring to Fig. 1, a kind of novel bearing enclosure dust cover combination press-in die providing in figure, comprises pressing mold base 100, guide-localization mould 200 and pressing mold 300.
Guide-localization mould 200 is the external diameter that cylindrical structural and its external diameter equal the inner ring 430 of bearing 400, the guide-localization mould 200 wherein middle part of an end face is provided with a positive stop lug boss 210, the external diameter of this positive stop lug boss 210 is slightly less than the internal diameter of bearing 400 while it is highly less than the height of bearing 400, meanwhile, the height sum of positive stop lug boss 210 and positioning boss 120 is less than or equal to the height of bearing 400.One end that guide-localization mould 200 is provided with positive stop lug boss 210 is buckled on the upper-end surface 420 of bearing 400, and positive stop lug boss 210 just inserts in bearing 400, and the step surface 220 being formed by positive stop lug boss 210 and guide-localization mould 200 is conflicted in the upper-end surface of bearing 400.
Pressing mold 300 is the cylinder end of with, the internal diameter of pressing mold 300 is greater than the external diameter of guide-localization mould 200 slightly, pressing mold 300 is enclosed within on guide-localization mould 200, the end face 230 of guide-localization mould 200 just conflict pressing mold 300 cylinder the end inwall 310 on, and the step surface 220 of guide-localization mould 200 just with pressing mold 300 cylinder an end face 320 flush.The thickness of the cylindrical shell of pressing mold 300 equals the inner ring 430 of bearing 400 and the width of the groove 450 that outer ring 440 forms.
When the oil sealing dust cover 460 of bearing 400 is installed, first bearing 400 is enclosed within the positioning boss 120 on pressing mold base 100, bearing 400 is positioned; The one end that again guide-localization mould 200 is provided with to positive stop lug boss 210 is buckled on bearing 400; Then, oil sealing dust cover 460 is placed on well to the end face 410(420 of bearing 400 by guide-localization mould 200) on; Finally, pressing mold 300 is inserted in guide-localization mould 200, in the groove 450 that the inner ring 430 that adopts press machine to act on pressing mold 300, oil sealing dust cover 460 to be pressed into bearing 400 and outer ring 440 form, due to the end face 230 of guide-localization mould 200 carry out after pressing mold 300 is pressed into spacing, ensured oil sealing dust cover 460 be pressed into after within certain tolerance range.The oil sealing dust cover 460 of bearing 400 other ends is to be also pressed into according to the method described above in bearing 400.
In order to ensure that pressing mold base 100, guide-localization mould 200 and pressing mold 300 are more accurate in combination assembling, at pressing mold base 100, guide-localization mould 200 and pressing mold 300 center, coaxial through hole 130,240,330 is set respectively, in the time of combination assembling, available one pin that is slightly less than through hole 130,240,330 internal diameters, successively through through hole 130,240,330, has effectively improved the precision that oil sealing dust cover 460 is installed.For make pressing mold base 100, guide-localization mould 200 and pressing mold 300 be more prone in combination assembling, faster, the edge of the end face of positioning boss 120, positive stop lug boss 210, guide-localization mould 200 is ground into inclined-plane.
More than show and described basic principle of the present utility model and major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that in above-described embodiment and specification, describes just illustrates principle of the present utility model; do not departing under the prerequisite of the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
