Description
Technical field
The present invention relates to a kind of processing method of extra large size bearing with pillar hole tapered roller body.
Background technology
Extra large size bearing band pillar rolling element is because product size is big, simple grain weight weight (14kg-18kg), big small end outer diameter ruler
It is very little differ greatly, difficulty of processing it is big, the professional lathe of rolling element processing has no ability to processing, always using single unit in universal lathe
Processed on C620, Vehicle Processing technique is：Roughing external diameter, end face are used as reference plane → u-turn open width allowance, centering → turn
Drilling machine drilling (shown in Figure 1) → carriage return two top flatcars of bed go out end face and external diameter as clamping benchmark (referring to Fig. 2 institutes
Show) → u-turn clamping benchmark, open width and the endoporus conical surface, circular arc chamfering → smart open width height → car endoporus conical surface and circular arc are reversed end for end again
The big end sphere (referring to shown in Fig. 3, Fig. 4) of chamfering → car system → rough turn rolling element male cone (strobilus masculinus) (the shown in Figure 5) → upper cylinder heart
Axle smart car male cone (strobilus masculinus) (the shown in Figure 6) → cylindrical arc angle in large and small end (shown in Figure 7).
Because each surface of rolling element is through excessive benchmark, multiple clamping completion, its shape such as axiality, perpendicularity each other
Position tolerance is unstable.Rolling element outside dimension, sphere radian and each circular arc chamfering are not of uniform size.Such other rolling element is using single
People's unit is processed because being influenceed by lathe and operator's level of skill, and every rolling element outside dimension is unstable, and big end sphere is not up to
To requiring, big small end circular arc chamfering disunity has influence on the presentation quality of bearing products by the gross after the completion of Product processing, it is impossible to full
The quality requirement that sufficient bearing user increasingly improves.
The content of the invention
It is an object of the invention to provide a kind of processing method of extra large size bearing with pillar hole tapered roller body, it can reduce
Procedure of processing, improve product quality and production efficiency.
A kind of processing method of extra large size bearing with pillar hole tapered roller body, it is particular in that, including following step
Suddenly：First with lathe car roughing outer-diameter end face benchmark → u-turn open width allowance, centering → turn drilling machine bore endoporus → return
Lathe finishes benchmark → upper numerical control lathe wheeled litter clamped one time car with two pinnacle car small ends and goes out large end face sphere, the internal-and external diameter conical surface
And circular arc chamfering → turn around smart open width height, the small end internal-and external diameter conical surface and circular arc chamfering.
Beneficial effects of the present invention are as follows：Reduce extra large size bearing band pillar hole tapered roller body Vehicle Processing step, machine
Bed and operating personnel's occupancy decline 50%, are integrally improved product quality and production efficiency, alleviate the work of lathe process
Intensity, reduces the processing capacity of grinding machine process, eliminates the use of cylindrical mandrel, and the making and material for having saved cylindrical mandrel disappear
Consumption, reduces production cost.

Embodiment
Embodiment 1：
By such rolling element, processing technology is changed on C620 (general) lathe press from both sides processing with Double Tops applicant after piercing
Small end external diameter, end face are made after clamping benchmark, and inside and outside footpath circular conical surface, big end are completed by the C630 numerically controlled lathes clamped one time transformed
Sphere, panel height and each R portions chamfering.I.e. by the rolling element work that multiple clamping is completed on C620 lathes by being transformed into numerical control
C630 numerically controlled lathes clamped one time, which is concentrated, to be completed.
Technique is after the present invention is improved：With C620 lathe car roughing outer-diameter end faces benchmark → u-turn open width allowance, beat
Centre bore → turn drilling machine brill endoporus (as shown in Figure 1) → carriage return bed with two pinnacle car small ends finishing benchmark (as shown in Figure 2)
→ upper numerical control lathe clamped one time car goes out large end face sphere, the internal-and external diameter conical surface and circular arc R chamfering (as shown in Figure 8) → turn around smart open width
High, the small end internal-and external diameter conical surface and circular arc R chamfering (as shown in Figure 9).
Compared with background technology, the more former technique of processing method after the present invention is improved all is significantly increased in every respect, first
Product quality is first ensure that, solves that the outside dimension size occurred in the processing of former technique is unstable, internal-and external diameter axiality is poor, greatly
Sphere radian and the skimble-scamble problem of internal-and external diameter R circular arc chamferings are held, product quality has obtained procurator and lower process operations person
Accreditation and favorable comment, meet quality demand of the bearing user to bearing roller.Next reduces lathe and artificial occupancy
Rate, existing technique alleviates the labor intensity of lathe operation person, reduced than reducing 50% needed for former technology machine and needed for personnel
The workload of grinding operations person, saves the making use and material consumption of cylindrical mandrel.Avoid multiple clamping and work simultaneously
Carrying between sequence, and then production efficiency is improved, production cost is reduced, good economic benefit is achieved.Realized after improvement
Clamped one time completes the processing on the multiple surfaces of bearing roller, improves the inside and outside footpath axiality of product, circular arc chamfering is big everywhere
Small and size unified degree, it is ensured that product appearance quality.
