Description
Technical field
The present invention relates to fixture during a kind of a kind of fixing device, particularly bearing outer ring processing, specifically one
Plant the accurate hard turning bearing outer ring special fixture of machining.
Background technology
Bearing outer ring is the important component of bearing, is developed rapidly recently as economic with the level of production progressively
Improve, the precision of plant equipment also more and more higher, bearing directly affects the matter of a whole set of plant equipment as an important component
Amount, and bearing outer ring directly affects the quality of bearing as the important component of bearing.
It is well known that the requirement on machining accuracy of precision bearing is high, while bearing outer ring belongs to thin-walled base part, Er Qiecai
Material particularity, the processing method generally use grinding of current precision bearing outer ring, but this processing mode have the disadvantage that can not
Overcome：（1）Grinding can produce high temperature, change the metallographic structure on bearing machining surface, influence the design attributes of bearing and make
Use the life-span；（2）The residual stress influence dimensional accuracy that processing is produced；（3）Process flow steps are more, and processing efficiency is low.
Relative to grinding mode, the processing mode that bearing outer ring is processed at present also has one kind to be hard turning technology, firmly
Turning technology is to use PCBN, diamond, ceramic material cutter, is processed on high rigidity, high precision machine tool, suitable
Under parameter selection, the surface quality processed is equal to the bearing outer ring that even above grinding method is processed, and hard turning side
Formula can obtain more uniform metallographic structure state and deeper residual compressive stress state, therefore hard turning processing mode can take
For the conventional machining process of current precision bearing, but hard turning processing mode processing efficiency is than relatively low, needed during hard turning by
Bearing outer ring blank is fixed, and when blank bearing outer ring is worked into certain precision, the wall thickness of outer ring can be thinning, if externally
Circle is further processed, and is very easy to cause race deformation, is influenceed the precision of bearing outer ring.In the prior art, hard turning is processed
During bearing outer ring, have to the fixing means of bearing outer ring：1. being fixed using scroll chuck, this fixed form is local pressure, dress
The deformation of outer ring can be directly resulted in after folder, turning is carried out during processing on the blank deformed, while the lathe tool of processing is produced
Raw cutting force also results in the deformation of part in itself, under remaining on board during lathe, and measurement circularity, size etc. are all qualified, but
Unclamp after scroll chuck, bearing outer ring can be deformed at once；2nd, electromagnetism fixture rail, is held outside blank bearing to be processed using electromagnet
One end face of circle, carries out turning inner hole processing, although can so solve problem on deformation, uses this fixture, in order to be able to
Stabilization during turning is enough kept, it is necessary to which great absorption affinity, this absorption affinity can cause part another after release is machined
The deformation in individual direction, causes the underproof situation of end face plane degree.3rd, lasso endoporus fixture, using with part to be processed size phase
The cast iron mold principle of adaptation, entangles bearing outer ring and fixes.But poor effect, source of error occur is, the wall of workpiece blank is thin,
Easy stress deformation, if the anchor point of clamping point and workpiece is misaligned, the workpiece of completion of processing after clamping force is removed because
The internal stress effect that clamping of the process to workpiece is caused, workpiece will produce elastic deformation, cause clamping force to remove front and rear
Size is inconsistent.
Therefore, those skilled in the art, which needs badly, develops the new construction fixture that a kind of suitable hard turning processing technology is used, phase
For prior art, it is possible to increase bearing outer ring internal diameter size, circularity, the bounce of internal diameter circle, the processing of axial dimension essence after processing
Degree.
