Platform, rectangular boss is located at round platform top, and both are structure as a whole, and arranges draw-in groove, it is oblique fixed that draw-in groove has in rectangular boss
Position hole, oblique positioning in the hole setting guiding drill bushing；Described round platform is formed using the copper rod smart car of suitable size, rectangular boss with
Draw-in groove milling in vertical machining centre forms；Rectangular surfaces in rectangular boss are technical face, during for processing oblique location hole
Line centering.
The processing of oblique location hole in guide: according to the status requirement of inclined oil hole of air in product drawing, in advance special
The access site of oblique location hole is determined with the method for manual setting-out on drill guide device；Process three-jaw during oblique location hole
Target drill guide external diameter fixed by chuck, using vertical machining centre guide rail between t type groove and pressing plate, t shape block etc. fixing
Scroll chuck, measures, with bevel protractor, the 45 ° of angles ensureing between scroll chuck and machine tool guideway, drilling processing after positioning clamping.
The processing of guiding drill bushing: for ensureing the wearability of guide, embedded in the oblique location hole in guide
Guiding drill bushing, guiding drill bushing and guide interference fit；Guiding drill bushing, using the steel rivet after Ageing Treatment, completes embedding
Enter the rivet that rear milling draw-in groove bottom is protruded, finally drilling bullport in rivet, that is, complete to guide the processing of drill bushing, bullport
Centering, positioning, clamping mode consistent with the processing mode of location hole oblique in guide.
The processing of b: inclined oil hole of air: by the round platform diameter periphery of target drill guide and determining of pocket bore dia arc surface
Position cooperation, draw-in groove bottom and retainer pocket bottom hole portion location fit, load each pocket hole of retainer one by one, are bored with manual and electric
Cut processing inclined oil hole of air.
The present invention is directed to the processing difficulties of this retainer inclined oil hole of air, steady using target drill guide means guide drill bit
Determine feed；Solve drill bit frangibility in the processing of this inclined oil hole of air, exceed the difficult problems such as existing machine tooling scope, by electric hand drill
Penetration rate and chip removal can preferably being held, thus completing the processing of oilhole, reducing processing cost it is ensured that the design of product
Require.

Specific embodiment
In conjunction with accompanying drawing, the specific embodiment of the present invention is described.
Retainer 3 as shown in Figure 1, has retainer pocket hole 2 thereon, has inclined oil hole of air in the bottom in retainer pocket hole 2
1, a kind of bearing holder inclined oil hole of air processing method of the present invention, it mainly processes inclined oil hole of air as shown in Figure 1
1, it comprises the following steps:
A: the making of target drill guide (frock): guide is by round platform 22, rectangular boss as shown in Fig. 2, Fig. 3, Fig. 5
