Description

Rolling bearing chamfering facility

Technical field

The utility model relates to a kind ofly fixedly uses chamfer tool to bearing.

Background technology

Bearing (" Bearing ", Japan's person " axle is subjected to ") is to work the parts of fixing and reducing the load coefficient of friction in mechanical transmission course.Also can say, when other parts produce relative motion each other on axle, be used for reducing the fixing parts of coefficient of friction and retainer shaft center in the power transmission process.Bearing is a kind of very important parts in the contemporary plant equipment.Its major function is the supported mechanical rotary body, in order to the mechanical load coefficient of friction of reduction equipment in transmission process.Press the difference of motor element frictional property, bearing can be divided into rolling bearing and sliding bearing two classes.Usually the bearing installation is by forcing press power to be added on the sleeve pipe, and bearing press mounting is fixed axle to axle.The radial and axial maximum chamfering limit one of bearing finished products chamfering circular arc part is asymmetric, axially greater than radially, its objective is to form an assembling guide angle, is beneficial to bearing and installs.The design chamfering profile of chamfering profile and size has circular arc and straight line to add two kinds on circular arc. and rear a kind of chamfering profile is more satisfactory.Because the Vehicle Processing of pure circular arc chamfering profile is difficult to control, after the heat treatment, behind milled external diameter and the end face. axial, radial coordinate changes more too, easily causes the finished product chamfering limit overproof.Because the bearing diameter size is different, after bearing was installed, in order to prevent its axial displacement in hole in piece part, the circumference actinal surface at Assembly part and bearing fit position should have chamfering generally speaking, therefore needed the instrument of the many special uses of design to its chamfering.Prior art usually adopt hand-held beveler detachable blade to foreign round, endoporus, mounting hole, inside and outside chamber edge chamfering.Next is to adopt the manual chamfering that is rolled in the enforcement of aperture, top and bottom, bearing two ends by roller, and manual depth of chamfering is difficult to ensure card, but mainly is that bearing is the spherical joint bearing of universal rotational, is difficult for the location.

Summary of the invention

Task of the present utility model provides a kind of simple to operation, the chamfering accurate positioning, and the degree of depth is adjustable, the bearing chamfer instrument that process velocity is fast.

The technical scheme that its technical problem that solves the utility model adopts is: a kind of rolling bearing chamfering facility, comprise, one end is shaped with axial location lead 12, one end is shaped with and connects the power rotary device footstalk, the middle part is shaped with the rotation positioning core axle 6 of disjunctor rectangle cube 11 and the ring flange base 7 of back-up roller dynamic bearing Assembly part 8, it is characterized in that, disjunctor rectangle cube 11 central axis both sides at described rotation positioning core axle 6, be arranged with by the connection of horizontal thread screw mandrel, act in opposite directions the two moving chamfering inclined-plane roller 4 of Assembly part bearing circumference mouth fillet surface.

The beneficial effects of the utility model are,

The power that the utility model utilizes the drilling machine rotation to produce rolls chamfering to bearing assemble part aperture, and simple to operation, convenient and swift, the chamfering accurate positioning is reliable, and machining accuracy is high.Axial location lead 12 is by dead eye, guarantee to implement to roll in the chamfer process spherical joint bearing centre position accurate, solved the problem that bearing chamfer is difficult for the location.The degree of depth of chamfering can be regulated arbitrarily according to actual needs by having the drilling machine of axial scale marker, has solved the bearing chamfer Assembly of the parts stage, and the chamfering location is inaccurate, the wayward problem of the degree of depth.And all rollers roll the mode bearing chamfer all can adopt this kind structure.

Description of drawings

Fig. 1 is the fixing front view of using the broken section of chamfer tool of the utility model bearing.

Among the figure: 1 screw mandrel, 2 spinning nuts, 3 rolling bearings, 4 chamfering inclined-plane rollers, 5 adjust circle, 6 rotation positioning core axles, 7 ring flange bases, 8 rolling bearing Assembly parts, 9 power set, 10 footstalks, 11 disjunctor rectangle cubes, 12 axial location leads.

The specific embodiment

At a kind of most preferred embodiment that rolling bearing Assembly part 8 side face ports is carried out chamfering shown in Figure 1, have an end and be shaped with axial location lead 12, one end is shaped with the footstalk 10 that connects power rotary device, and the middle part is shaped with the rotation positioning core axle 6 of disjunctor rectangle cube 11 and the ring flange base 7 of back-up roller dynamic bearing Assembly part 8.Footstalk 10 and axial location lead 12 lay respectively at the axial two ends of disjunctor rectangle cube 11, interconnect to be integrated.Disjunctor rectangle cube 11 centers of rotation positioning core axle 6 are shaped with a through hole, and threaded screw rod connects wherein.Footstalk 10 connecting power devices, axial location lead 12 stretches in ring flange base 7 pilot holes of rolling bearing Assembly part 8 lower surfaces by the dead eye of rolling bearing Assembly part 8.Ring flange base 7 is positioned at the lower surface of rolling bearing Assembly part 8, is shaped with the annular groove boss of back-up roller dynamic bearing Assembly part 8 spherical joints on it.

At the disjunctor rectangle cube 11 central axis two ends of described rotation positioning core axle 6, be arranged with by the connection of horizontal thread screw mandrel, act in opposite directions the two moving chamfering inclined-plane roller 4 of bearing assemble part circumference actinal surface.Screw mandrel 1 is by being positioned at the disjunctor rectangle cube centre bore at rotation positioning core axle 6 middle parts, the chamfering inclined-plane roller 4 that connects two ends, fastening by spinning nut 2 respectively, and two chamfer inclined-plane rollers 4 respectively are equipped with ball bearing 3, and ball bearing 3 inner side ends are provided with the adjustment circle 5 by screw mandrel 1.The power set 9 of chamfering inclined-plane roller 4 by linking to each other with its upper end fit in rolling bearing Assembly part 8 fillet surfaces from top to bottom.

During chamfering, rotation positioning core axle 6 top footstalks 10 cylinder connecting power devices, lower shaft places the spherical joint brearing bore of rolling bearing Assembly part 8 to positioning guide column 12, and imports flange and try to get to the heart of a matter between pilot hole in the seat 7.Start power set 9, withstand bearing chamfer face two ends from top to bottom, implement to roll bearing chamfer by the circular motion of roller.

Usually the lower surface of rolling bearing Assembly part 8 original states is a smooth flat, roller can be absorbed in the dead eye limit by pressure, make rolling bearing Assembly part 8 circumference actinal surfaces produce plastic deformation, roller rolls along the bearing aperture and rolls, rolling bearing Assembly part 8 upper surfaces can produce the flange distortion that stops bearing axial displacement, and bearing is fixed in the Assembly part, and the one side chamfering is complete, again another side is carried out chamfering, depth of chamfering is guaranteed by the drilling machine graduation indication with axial scale marker.
