The access site of oblique positioning hole is determined on drill guide device with the method for manual setting-out；Three-jaw when processing oblique positioning hole
Chuck fixes target drill guide device external diameter, and three are fixed using the T-slot between vertical machining centre guide rail and pressing plate, T-shaped block
Dog chuck, the 45 ° of angles ensured between scroll chuck and machine tool guideway, the next drilling processing of locating clip are measured with bevel protractor.
Guide the processing of drill bushing：It is embedded in the oblique positioning hole in guide device for the wearability of guarantee guide device
Drill bushing is guided, guiding drill bushing is interference fitted with guide device；Drill bushing is guided to be completed embedding using the steel rivet after Ageing Treatment
Enter the rivet of rear milling neck bottom protrusion, finally the drilling bullport in rivet, that is, complete the processing of guiding drill bushing, bullport
Centering, positioning, clamping mode it is consistent with the processing mode of oblique positioning hole in guide device.
b:The processing of inclined oil hole of air：The periphery of round platform 22 of target drill guide device and the positioning of retainer pocket hole wall are matched somebody with somebody
Close, neck bottom and retainer pocket bottom hole portion location fit, load each pocket hole of retainer one by one, boring drilling with manual and electric adds
Work inclined oil hole of air.
The present invention is directed to the processing difficulties of the retainer inclined oil hole of air, steady using target drill guide means guide drill bit
Determine feed；Solve drill bit frangibility in inclined oil hole of air processing, beyond problems such as existing machine tooling scopes, pass through electric hand drill
Penetration rate and chip removal can be preferably held, so as to complete the processing of oilhole, processing cost is reduced, ensure that the design of product
It is required that.
