Abstract
The invention discloses an outer ring loading tool of a tapered roller bearing, which is characterized in that a bearing locating shaft is fixedly mounted in a pressure head through a bolt; three jack catches are arranged on the bottom end face of the bearing locating shaft; the jack catches are mounted on the bottom of the bearing locating shaft through horizontal round pins; a jack catch spring is arranged in the bearing locating shaft on the corresponding position along axial direction; each jack catch with a lever structure takes the corresponding horizontal round pin as a rotating pivot; each jack catch spring is resisted on the upper surface of the inner end of the corresponding jack catch; the tool can act on the lower surface of the inner end of each jack catch; a convex edge protruded along radial direction is arranged on the bottom side of the outer end of each jack catch; the bearing outer ring can be supported on the convex edge. The outer ring loading tool can be convenient for loading in the press fitting process of the bearing outer ring; ensures coaxiality; increases press fitting precision, and simplifies the structure, and the bearing outer ring is convenient to process and assemble.
Description
Technical field
The present invention relates to a kind of material loading frock being applied in the press-loading process of gearbox jackshaft taper roll bearing outer ring.
Background technology
In prior art, during in automobile assembling industry, gearbox midship shaft bearing outer ring press-fits, the material loading frock of bearing outer ring adopts structure as shown in Figure 1, urethane pad 1 is connected with rotating prevention sleeve 7 by pressing plate 2 use screws 5, the periphery of rotating prevention sleeve 7 is provided with locating ring 6, on the outer circumference surface of urethane pad 1, have annular groove, the distortion by urethane pad 1 is entrapped in bearing outer ring 20 in annular groove.In the process being press-fited downwards with dynamic head 4 by seaming chuck connecting axle 9 by seaming chuck seat 8, after the bottom end face of urethane pad 1 is being encountered workpiece compression, be with dynamic pressure plate 2, bearing locating shaft 3 together with rotating prevention sleeve 7 material returned that moved upward, after the material returned, under the effect of back-moving spring 10, reset.But there is following problem in this version:
1, the bad control of the deflection of urethane pad, deflection is too large, during artificial loading, requires great effort, and strengthens labor strength; Deflection is too little, because the scale error of workpiece causes part workpiece not hang the defective work piece that comes off; Meanwhile, urethane pad is easy to wearing and tearing, constantly needs to change in use procedure;
2, the distortion of urethane pad is uneven, and inaccurate to the heart while causing bearing outer ring material loading, axiality is not high, thereby causes equipment precision on the low side;
3, in press-fiting process, the automatic material returning of bearing outer ring is encountered the realization that moves upward of workpiece compression band dynamic bearing locating shaft 3 relative pressure heads 4 and bearing outer ring by the bottom end face of urethane pad, then by spring reset, overall structure more complicated, is unfavorable for processing and assembling.
Summary of the invention
The present invention is for fear of the existing weak point of above-mentioned prior art, and a kind of taper roll bearing outer ring material loading frock is provided, and to facilitate at bearing outer ring, press-fits the material loading in process, reduces labor intensity; Guarantee axiality, improve and press-fit precision; And simplified structure, convenient processing and assembling.
The present invention is that technical solution problem adopts following technical scheme:
The feature of a kind of taper roll bearing material loading of the present invention frock is: bearing locating shaft is fixedly mounted in pressure head by screw, on the bottom end face of bearing locating shaft, be provided with three claws, described claw is arranged on the bottom of bearing locating shaft by horizontal round pin, in the bearing locating shaft of correspondence position, be provided with vertically claw spring; The claw of lever construction is that to take described horizontal round pin be rotating fulcrum, and claw spring is pressed on the upper surface of the inner end of claw; Workpiece can act on the lower surface of the inner end of claw; There is a chimb radially protruding out on base in the outer end of described claw, and described bearing outer ring can hold in the palm and hold on described chimb.
The feature of a kind of taper roll bearing material loading of the present invention frock is also: described three claws are uniformly distributed on the bottom end face of described bearing locating shaft.
Compared with the prior art, beneficial effect of the present invention is embodied in:
1, the present invention is by spring-force driven dual clamp shaft bearing outer-ring on claw, can be according to bearing outer ring weight the size in claw spring fitting face shimming regulating spring power, facilitate material loading;
2, the conical surface of bearing locating shaft can be close in material loading rear bearing of the present invention outer ring, and axiality is higher, and equipment precision significantly improves before;
3, claw structure of the present invention significantly improves than urethane pad durability;
4, the pressured contracting claw of the material loading material returned of the present invention spring is stirred claw rotation, and the upper material returned is convenient, and simple in structure, assembly process process improves greatly.
Accompanying drawing explanation
Fig. 1 is prior art structural representation;
Fig. 2 is structural representation of the present invention;
Fig. 3 is another use view of the present invention;
Number in the figure: 1 urethane pad; 2 pressing plates; 3 bearing locating shafts; 4 pressure heads; 5 screws; 6 locating rings; 7 rotating prevention sleeves; 8 seaming chuck seats; 9 seaming chuck connecting axles; 10 springs; 12 claws; 13 horizontal round pins; 14 claw springs; 15 chimbs.
The specific embodiment
Referring to Fig. 2 Fig. 3, in the present embodiment, the version of taper roll bearing material loading frock is:
Bearing locating shaft 3 is fixedly mounted in pressure head 4 by screw 5, on the bottom end face of bearing locating shaft 3, be provided with three claws 12, claw 12 is arranged on the bottom of bearing locating shaft 3 by horizontal round pin 13, in the bearing locating shaft 3 of correspondence position, be provided with vertically claw spring 14; The claw 12 of lever construction is that to take horizontal round pin 13 be rotating fulcrum, and claw spring 14 is pressed on the upper surface of the inner end of claw 12; Workpiece 21 can act on the lower surface of the inner end of claw 12; There is a chimb radially protruding out 15 on base in the outer end of claw 12, and bearing outer ring 20 can hold in the palm and hold on chimb 15.
In concrete enforcement, be to improve stability, three claws 12 on the bottom end face of bearing locating shaft 3 for being uniformly distributed.
The course of work: pack claw 12 into bearing locating shaft 3 by horizontal round pin 13, claw spring 14 is arranged in the axle spring hole of bearing locating shaft 3, then integral body is arranged on pressure head 4 with screw 5, claw 12 can freely rotate around round pin 13, and under the use of the spring force of claw spring clamp shaft bearing outer-ring 21, can select suitable claw spring and claw according to the bearing outer ring of different size, weight.During material loading, by claw spring-compressed, can be to bearing set outer ring 20 on bearing locating shaft 3, claw spring reset after loosing one's grip, bearing outer ring 20 is clamped location (shown in Fig. 2) by claw; Press-fit in process, workpiece 21 acts on the lower surface of the inner end of claw 12, and claw is rotated, and bearing outer ring 20 departs from the clip of claw and realize the material returned (shown in Fig. 3).
