Abstract
The invention relates to a grinding method for bearings with lock points. The grinding method comprises the steps of firstly, rough lapping of channels; secondly, precision lapping of the channels; thirdly, final grinding of slopes; fourthly, carrying out acute angle removing, flaw detecting, outer-ring outer diameter coping, laser typing and lock point grinding on work-pieces which have undergone the previous step of final grinding of the slopes. According to the invention, parts difficult to machine are machined in the first step so that the standard corresponding to machining in the next step can keep unchanged, the form and location tolerance requirements of the standard can be met in the second machining step, and therefore the matching requirement in final use can be guaranteed. The height of the lock points can be guaranteed, and disqualification of finished parts is eliminated.
Description
Technical field
The present invention relates to lappingout processing and mill manufacture field.
Background technology
Current mill machining control lock point height operation is as follows:
Slightly grind raceway groove → mill filling slot, mill slope (control lock point height) → go acute angle → with nothing left decorations → flaw detection → lappingout raceway groove →... ...
The shortcoming of above-mentioned technique: 1. found out by above-mentioned flow process, operation processing dispersion, is processing equipment needs wait after slightly grinding processing after; 2. uncontrollable to the height of lock point during lappingout raceway groove, often because highly defective assembling and the other factory of causing of lock point reprocesses.
Summary of the invention
The present invention in order to solve above-mentioned existing problems, and provides a kind of locking spot bearing mill processing method.
One of the present invention locking spot bearing mill processing method, it carries out according to following steps:
One, slightly raceway groove is ground
Adopt mechanical compaction formula lappingout, use tyre cushion end face location, fulcrum external diameter is located, and utilize two symmetrical double-roller supporting external diameters that adopt to drive workpiece to rotate, oilstone realizes raceway groove microstoning along channel center axial wobble;
Two, lappingout raceway groove
Adopt and process same mode and carry out lappingout raceway groove with slightly grinding;
Three, slope is ground eventually
1), be with the inner ring of filling slot, outer ring product uses special breach machine by technological requirement grinding;
2), the product outer ring of locking point uses MZ208 equipment to grind slope by after technological requirement adjustment angle, and inner ring uses H123 equipment by technological requirement grinding:
Four, the workpiece after previous step eventually mill slope is carried out following operation, remove acute angle, flaw detection, outer ring reconditioning external diameter, laser is typewrited, and finally carries out lock point grinding.
The present invention comprises following beneficial effect:
The first step of the present invention completes the operation at more unmanageable position, and benchmark relative during to ensure that next step is processed is constant, and second step adds the Geometrical Tolerance Principle completed man-hour in benchmark, thus cooperation requirement when ensureing final utilization.Lock point height can be ensured completely, stopped the defective phenomenon of fabricated part.

Detailed description of the invention
Detailed description of the invention one: the one locking spot bearing mill processing method of present embodiment, it carries out according to following steps:
One, slightly raceway groove is ground
Adopt mechanical compaction formula lappingout, use tyre cushion end face location, fulcrum external diameter is located, and utilize two symmetrical double-roller supporting external diameters that adopt to drive workpiece to rotate, oilstone realizes raceway groove microstoning along channel center axial wobble;
Two, lappingout raceway groove
Adopt and process same mode and carry out lappingout raceway groove with slightly grinding;
Three, slope is ground eventually
1), be with the inner ring of filling slot, outer ring product uses special breach machine by technological requirement grinding;
2), the product outer ring of locking point uses MZ208 equipment to grind slope by after technological requirement adjustment angle, and inner ring uses H123 equipment by technological requirement grinding:
Four, the workpiece after previous step eventually mill slope is carried out following operation, remove acute angle, flaw detection, outer ring reconditioning external diameter, laser is typewrited, and finally carries out lock point grinding.
Detailed description of the invention two: present embodiment and detailed description of the invention one support external diameter unlike: described double-roller and drive workpiece to rotate to refer to and adopt four-head lapping machine to drive workpiece to rotate.Other is identical with detailed description of the invention one.
Detailed description of the invention three: present embodiment and detailed description of the invention one unlike: first carry out channel dimensions sorting before grinding, according to separation results processing filling slot and lock point, and detect.Other is identical with detailed description of the invention one.
Content of the present invention is not limited only to the content of the respective embodiments described above, and the combination of one of them or several detailed description of the invention equally also can realize the object of inventing.
Embodiment 1
The one locking spot bearing mill processing method of the present embodiment, it carries out according to following steps:
One, slightly raceway groove is ground
Adopt mechanical compaction formula lappingout, use tyre cushion end face location, fulcrum external diameter is located, and utilize two symmetrical double-roller supporting external diameters that adopt to drive workpiece to rotate, oilstone realizes raceway groove microstoning along channel center axial wobble;
Two, lappingout raceway groove
Adopt and process same mode and carry out lappingout raceway groove with slightly grinding;
Three, slope is ground eventually
1), be with the inner ring of filling slot, outer ring product uses special breach machine by technological requirement grinding;
2), the product outer ring of locking point uses MZ208 equipment to grind slope by after technological requirement adjustment angle, and inner ring uses H123 equipment by technological requirement grinding:
Four, the workpiece after previous step eventually mill slope is carried out following operation, remove acute angle, flaw detection, outer ring reconditioning external diameter, laser is typewrited, and finally carries out lock point grinding.
Below slightly grind raceway groove and lappingout raceway groove ensures that raceway groove meets technological requirement, finally carry out lock point grinding and ensure lock point height, meet instructions for use.
The first step of the present embodiment completes the operation at more unmanageable position, and benchmark relative during to ensure that next step is processed is constant, and second step adds the Geometrical Tolerance Principle completed man-hour in benchmark, thus cooperation requirement when ensureing final utilization.Lock point height can be ensured completely, stopped the defective phenomenon of fabricated part.
