Description
Technical field
The invention belongs to technical field of bearing processing, in particular to a kind of back lining bearing processing technology.
Background technique
Back lining bearing is usually that 6 sets of bearings are assembled on a mandrel to use when in use, and this requires be assembled to one
H value (the distance between bearing inner ring interior diameter and outer ring outer diameter) the phase mutual deviation of 6 sets of bearings on root mandrel is controlled in minimum model
In enclosing, industry requirement is within 0.005mm at present, and otherwise, in use process, the big bearing endurance of H value is larger, is easy damage
It is bad.
Currently, the processing technology of bearing is usually inner ring according to drawing normal process, after outer ring is produced, to the outer of outer ring
Diameter is polished, and wall-thickness measurement, is then grouped (6 one group) according to measurement record, then it is cooperated with inner ring, reference
Notification number is the Chinese utility model patent of CN205927703U.But the outer ring that this processing method is produced, often send out
First portion outer ring is larger because size deviates, and can not participate in the case where being grouped, so that reconditioning outer diameter again is needed, to be matched
Group.And then cause split bearing to be loaded repeatedly, reconditioning it is multiple, production efficiency is lower；It is overproof that the careless reconditioning in outer ring even occurs
Situation seriously affects machining accuracy.
On the other hand, the method for traditional reconditioning back lining bearing is that outer ring is removed, independent reconditioning outer ring outer diameter.But pass through
After the use of a period of time, the case where bearing outer ring is likely occurred ovalizing deflection, i.e. bearing outer ring convexity changes.If
Bearing outer ring ellipse is overproof, and Wall-Thickness Difference is not up to standard, then the reconditioning mode of existing only reconditioning outer diameter is difficult oval and wall
Thickness repairs.
Summary of the invention
The object of the present invention is to provide a kind of back lining bearing processing technologys, on the basis of prior art, by reconditioning axis
Bearing outer-ring outer diameter is changed to reconditioning outer diameter that bearing is integrally loaded using mould, direct reconditioning bearing H value, good processing accuracy, efficiency
It is high.
Above-mentioned technical purpose of the invention has the technical scheme that
A kind of back lining bearing processing technology, comprising the following steps:
S1: the fixed part of reconditioning mould is separated with movable part；
S2: the inner ring normally produced, rolling element group and outer ring to be grinding are cooperated, bearing to be grinding is formed；
S3: bearing to be grinding is caught on the mandrel of fixed part, and movable part is returned dress, and inner ring is pressed from both sides along axial
Tightly；
S4: the reconditioning mould for the bearing to be grinding that is loaded integrally is loaded on grinding machine, the top mould that holds out against of grinding machine
Mandrel；
S5: the oil nozzle of hydraulic pump and mandrel being connected, and is pressurizeed, and mandrel is gradually expanded and is in close contact with inner ring, will be interior
Circle is fixed as one with mandrel；
S6: grinding machine drives outer ring rotation, and reconditioning outer diameter.
Further, fixed part described in S1 includes mandrel, and the outer one end of the mandrel, which is equipped with, is used for axial grip inner ring
Mounting flange.
Further, the mandrel, which is externally provided with, fixes to clamp ring for axial restraint outer ring.
Further, described to fix to clamp between ring and the mounting flange by being fixedly connected with ring connection, the fixation
Clamping ring can be rotated around the mandrel.
Further, the mandrel is externally provided with expansion axle sleeve.
Further, movable part described in S1 include with the mandrel cooperation movable sleeve, the movable sleeve with it is described
Mandrel is detachably connected.
Further, the movable sleeve is externally provided with the loose flange for axial grip inner ring.
Further, the movable sleeve is externally provided with the movable clamping ring for axial restraint outer ring.
Further, the movable clamping ring is connect by being flexibly connected ring with the loose flange, the movable clamping
Ring can be rotated around the movable sleeve.
Compared with prior art, the beneficial effects of the present invention are:
1. individually dismantling outer ring in the prior art, the technique for carrying out reconditioning Selective assembly again to outer ring is compared, this hair
It is bright bearing to be integrally loaded reconditioning outer diameter using mould, it directly modifies bearing H value and therefore eliminates the grouping in traditional handicraft
Grouping is merged into a step with outer diameter reconditioning and completed by link, and machining accuracy is more preferable, more efficient.
2. being fixed inner ring in the way of hydraulic buckling, inner ring does not turn during reconditioning, outer ring rotation, close in clearance
In the case where O, practical reconditioning is outer ring wall thickness, and therefore, situations such as ovalizing deflection of outer ring, wall thickness is overproof there is not reconditioning result
Have an impact.
3. the cooperation of loose flange and mounting flange makes inner ring in axial grip, inner ring is along its axial direction during avoiding reconditioning
It is mobile.
4. due to movable clamping ring, fixes to clamp ring and can be rotated relative to movable sleeve and mandrel, utilizing activity folder
Tight ring and ring is fixed to clamp by outer ring under the premise of axial restraint, outer ring can be rotated relative to inner ring, to go on smoothly reconditioning.
