Description
Technical field
The utility model belongs to retainer manufacture field, relates generally to a kind of for bearing holder inclined oil hole of air
The target drill guide of processing.
Background technology
A kind of existing cylindrical roller thrust bearing solid cage is applied to large-size numerical control machine main shaft bearing, by setting
The inclined oil hole of air in meter processing brass retainer pocket bottom hole portion, increases the oil circuit in pocket hole, improves retainer with roller, rolling
Lubricant effect between road, and the amount of heat produced because rubbing in revolution with bearing running so that main shaft of numerical control machine tool bearing exists
Lubricate abundant in work, prevention bearing running hot failure, so as to improve the service life of bearing.
Existing in the market, the processing mode of the conventional electric spark of processing of inclined oil hole of air, efficiency is low, high cost.Existing five axle adds
The stroke of work center X-axis, Y-axis and Z axis is 1300 × 750 × 700mm, and the product external diameter has reached 971.5mm, added beyond five axles
The range of work at work center；Existing horizontal boring machine, drill thrust is big, it is impossible to 45 degree of angle inclined holes in machining small footpath.
Utility model content
The purpose of this utility model is to provide a kind of target drill guide of bearing holder inclined oil hole of air processing,
Processing problem for solving retainer inclined oil hole of air, reduces processing cost, it is ensured that the design requirement of product.
[M1] can adopt the following technical scheme that to realize：
A kind of described target drill guide for the processing of bearing holder inclined oil hole of air, it include round platform,
Rectangular boss, rectangular boss is located at round platform top, and both are structure as a whole, and is set and retainer pocket bottom hole portion in rectangular boss
The draw-in groove of location fit, sets on draw-in groove and set in oblique location hole, oblique location hole drilling guide sleeves；
The center line of described oblique location hole is in 45 degree of angles with horizontal line.
Described drilling guide sleeves and oblique location hole interference fit.
The utility model is bored for the processing difficulties of the retainer inclined oil hole of air using target drill guide means guide
Head stabilization feed；Solve the inclined oil hole of air processing in drill bit frangibility, beyond problems such as existing machine tooling scopes, by hand-held
Electric drill can preferably hold penetration rate and chip removal, so as to complete the processing of oilhole, reduce processing cost, it is ensured that product
Design requirement.
Brief description of the drawings
Fig. 1 is the inclined oil hole of air sketch in existing retainer pocket bottom hole portion.
Fig. 2 is structure diagram of the present utility model.
Fig. 3 is the top view of Fig. 2.
Fig. 4 is the processing sketch of inclined oil hole of air.
In figure：1st, inclined oil hole of air, 2, retainer pocket hole, 3, retainer, 4, draw-in groove, 5, drilling guide sleeves, 6, guide,
21st, round platform, 22, oblique location hole, 23, rectangular boss, → represent drill bit.
Specific embodiment
With reference to accompanying drawing, specific embodiment of the utility model is illustrated.
Retainer 3 as shown in Figure 1, the retainer pocket hole 2 with circumference uniform distribution thereon, at interval of a retainer pocket hole
2 bottom has inclined oil hole of air 1, and a kind of bearing holder inclined oil hole of air processing target drill that is used for described in the utility model draws
Device is led, it is mainly processing inclined oil hole of air as shown in Figure 1.
As shown in Figure 2 and Figure 3, described one kind is used for bearing holder inclined oil hole of air processing target drill guide,
It includes round platform 21, rectangular boss 23, and convex 23 of rectangle is located at the top of round platform 21, and both are structure as a whole, in rectangular boss 23
Upper setting and the draw-in groove 4 of retainer pocket bottom hole portion location fit, set oblique location hole 22 on draw-in groove 4, to ensure guiding dress
The wearability put, embedded steel drilling guide sleeves 5 in the oblique location hole 22 in guide（Material can select Ageing Treatment
Steel rivet afterwards, then the drilling bullport in rivet）, drill guide sleeves 5 and the interference fit of oblique location hole 22.Described
The center line of oblique location hole 22 is in 45 degree of angles with horizontal line, and drill guide sleeves and oblique location hole interference fit.
The diameter periphery of round platform 21 of target drill guide is matched somebody with somebody with the positioning of pocket bore dia arc surface as shown in Figure 4
Conjunction, the bottom of draw-in groove 4 and retainer pocket bottom hole portion location fit, load the retainer pocket hole at interval one by one, are bored with manual and electric
Cut processing inclined oil hole of air.Penetration rate and chip removal can preferably be held by electric hand drill, so as to complete the processing of oilhole.
