Abstract
The invention relates to a machining method of extra-large bearing cone rolling bodies with supporting column holes. The machining method is characterized by comprising the steps of adopting a lathe for turning the standard of the external diameter end surface in a rough machining mode; turning full width and allowance around and punching center holes; rotating a drilling machine for drilling inner holes; returning to the lathe for turning the finish machining standard of small ends through two centres; adopting a digitally-controlled lathe for turning large-end-surface spherical surfaces, internal-diameter and external-diameter conical surfaces and arc chamfers through one-time clamping; turning precise-leveling panel height, the internal-diameter and external-diameter conical surfaces of the small ends and the arc chamfers around. The machining method has the advantages that the machining steps of the extra-large bearing cone rolling bodies with the supporting column holes are simplified, the occupancy rate of machine tools and operating personnel is lowered by 50%, the product quality and the production efficiency are improved integrally, the labor intensity of processes of the lathe is lowered, the machining amount of processes of a grinding machine is lowered, cylindrical mandrels are avoided, manufacturing and material consuming of the cylindrical mandrels are avoided, and the production cost is lowered.
Description
Technical field
The present invention relates to a kind of processing method of extra large size bearing band pillar hole tapered roller body.
Background technology
Extra large size bearing band pillar rolling element because of product size large, simple grain Heavy Weight (14kg-18kg), large small end outside dimension differs greatly, difficulty of processing is large, professional lathe processed by rolling element does not have ability to process, adopt single unit to process on universal lathe C620 always, Vehicle Processing technique is: roughing external diameter, end face is as datum level → tune open width allowance, centering → turn drilling machine boring (shown in Figure 1) → carriage return bed two top flatcars go out an end face and external diameter clamps benchmark as clamping benchmark (shown in Figure 2) → tune, open width and the endoporus conical surface, the smart open width of circular arc chamfering → reverse end for end again is high → and the car endoporus conical surface and the large end sphere of circular arc chamfering → car system be (see Fig. 3, shown in Fig. 4) → rough turn rolling element male cone (strobilus masculinus) (shown in Figure 5) → upper cylindrical mandrel finish turning male cone (strobilus masculinus) (shown in Figure 6) → large, small end cylindrical arc angle (shown in Figure 7).
Due to each surface of rolling element be through many benchmark, multiple clamping completes, form and position tolerance such as axiality, perpendicularity is unstable each other for it.Rolling element outside dimension, sphere radian and each circular arc chamfering are not of uniform size.Such rolling element adopts single unit to process because affecting by lathe and operator's level of skill in addition, every part rolling element outside dimension is unstable, large end sphere does not reach requirement, large small end circular arc chamfering disunity, have influence on the presentation quality of bearing products by the gross after Product processing completes, the quality requirement that bearing user improves day by day cannot be met.
Summary of the invention
The object of this invention is to provide a kind of processing method of extra large size bearing band pillar hole tapered roller body, procedure of processing can be reduced, improve product quality and production efficiency.
A kind of processing method of extra large size bearing band pillar hole tapered roller body, its special feature is, comprise the steps: first with lathe car roughing outer-diameter end face benchmark → tune open width allowance, centering → turn drilling machine bore that endoporus → carriage return bed two pinnacle car small end fine finishining benchmark → go up numerical control lathe wheeled litter clamped one time car goes out large end face sphere, the internal-and external diameter conical surface and circular arc chamfering → turn around smart open width is high, the small end internal-and external diameter conical surface and circular arc chamfering.
Beneficial effect of the present invention is as follows: decrease extra large size bearing band pillar hole tapered roller body Vehicle Processing step, lathe and operating personnel's occupancy decline 50%, entirety improves product quality and production efficiency, alleviate the labour intensity of lathe operation, reduce the processing capacity of grinding machine operation, eliminate the use of cylindrical mandrel, saved making and the material consumption of cylindrical mandrel, reduced production cost.

Detailed description of the invention
Embodiment 1:
Applicant after processing technology changes into make clamping benchmark with Double Tops folder processing small end external diameter, end face on C620 (general) lathe after piercing by such rolling element, is completed inside and outside footpath taper seat by the C630 numerically controlled lathe clamped one time transformed, is held sphere, panel height and each R portion chamfering greatly.Concentrated by the C630 numerically controlled lathe clamped one time being transformed into numerical control by the rolling element work that multiple clamping completes on C620 lathe.
The present invention improves rear technique: with C620 lathe car roughing outer-diameter end face benchmark → tune open width allowance, centering → turn drilling machine bore that endoporus (as shown in Figure 1) → carriage return bed two pinnacles car small end fine finishining benchmark (as shown in Figure 2) → go up 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 is 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 improves all is significantly increased in every respect, first ensure that product quality, solve the outside dimension size instability, poor, the large end sphere radian of internal-and external diameter axiality and the skimble-scamble problem of internal-and external diameter R circular arc chamfering that occur in former processes, product quality obtains accreditation and the favorable comment of procurator and lower process operations person, meets the quality demand of bearing user to bearing roller.Next decreases lathe and artificial occupancy, and existing technique, than needed for former technology machine and reduce 50% needed for personnel, alleviates the labour intensity of lathe operation person, and the workload of the person that decreases grinding operations, saves making use and the material consumption of cylindrical mandrel.Avoid the carrying of multiple clamping and inter process simultaneously, and then improve production efficiency, reduce production cost, achieve good economic benefit.Achieve the processing that clamped one time completes the multiple surface of bearing roller after improvement, improve product inside and outside footpath axiality, the unified degree of circular arc chamfering size and size, ensure that product appearance quality everywhere.
