Description
Technical field
The present invention relates to a kind of processing method of auto parts and components, especially relate to a kind of taper roll bearing Internal and external cycle Vehicle Processing method.
Background technology
The existing history for many years of taper roll bearing is the most commonly used on lathe, automobile.Yet because technical reason, old-fashioned bearing inner race Vehicle Processing technology can not satisfy the requirement of present bearing process technology.Bearing technology with rapid changepl. never-ending changes and improvements be by in the market that enlarges fast and the strong competition between the bearing manufacturer, ripe the bringing gradually of industry.Chinese patent discloses a kind of Internal and external cycle manufacture method and device (publication number: CN101934340A) thereof, its method is: in first operation, heating and a cylindric raw material cutting into given size are carried out excellent suitability for press forming and formed first formed products, the periphery of this first formed products is configured as circle, and at one end face central authorities form the circular cone recess with the circular cone inner surface that diminishes gradually towards inside diameter, form diameter less than the internal diameter of the inner ring that will make and have the circular port of thin-walled bottom in the bottom central part of circular cone recess; In second operation, utilize blanking die that punch process is carried out in the thin-walled bottom of the circular port of first formed products, be formed on central portion and have diameter less than second formed products of the circular through hole of the internal diameter of the inner ring that will make; In the 3rd operation, when the periphery of the circular through hole of second formed products is forwards released, excellent suitability for press forming is carried out in hole enlargement on one side on one side, forms by outer ring portion and the 3rd formed products constituting with concentric inner ring portion of giving prominence to via mesosphere portion integratedly of this outer ring portion; In the 4th operation, by with inside and outside two forging dies and inside and outside two drifts the 3rd formed products being carried out twice punching press, stamp out Internal and external cycle simultaneously, form outer ring, inner ring and as the mesosphere of stampings.But the Internal and external cycle that this processes is come out also needs to machine, and operation is many during the Vehicle Processing of taper roll bearing inner ring, can not play the effect of product size stability, and the Vehicle Processing of existing taper roll bearing inner ring bearing is required can be than higher, otherwise operation will appear leaking.
Summary of the invention
The present invention provides a kind of taper roll bearing Internal and external cycle Vehicle Processing method, it mainly is that operation is many when solving the Vehicle Processing of existing in prior technology taper roll bearing inner ring, can not play the effect of product size stability, and the Vehicle Processing of existing taper roll bearing inner ring requires bearing can be than higher, otherwise the technical problem of operation etc. will occur leaking.
Above-mentioned technical problem of the present invention is mainly solved by following technical proposals:
A kind of taper roll bearing Internal and external cycle Vehicle Processing method of the present invention is characterized in that described method comprises:
A. the bearing inner race blank being put into the enterprising luggage folder of inner ring anchor clamps, is benchmark with the big plane of inner ring, processes inner ring facet, little rib external diameter, inner ring raceway, large-flange external diameter; And then process the big oil duct of inner ring, inner ring internal diameter successively;
B. carrying out clamping second time on the anchor clamps with being put into after the upset of whole bearing inner race blank, is benchmark with the inner ring facet, processes chamfering and internal diameter in the inner ring height, large-flange of bearing inner race, large-flange chamfering outward, namely goes out finished product taper roll bearing inner ring;
C. the bearing outer ring blank being put into the enterprising luggage folder of outer ring anchor clamps, is benchmark with big plane, outer ring, processes outer ring facet, the outer chamfering of non-basal plane, outer ring external diameter; And then process chamfering in the non-basal plane, outer ring raceway successively;
D. carry out the clamping second time on the anchor clamps of outer ring with being put into after the whole bearing outer ring blank upset, be benchmark with the outer ring facet, process the interior chamfering of outer ring height, basal plane, the outer chamfering of basal plane, the outer ring external diameter of bearing outer ring successively, namely go out finished product taper roll bearing outer ring.
The present invention adopts a kind of new technology, and the inside and outside circle of bearing adopts the numerical control car to process, and finishes whole manufacturing procedures and former technology comparison with 2 road technologies, adopts 8 procedures to finish in the past, needs only 2 procedures now and namely can finish.Inner ring technology 1: inner ring: car endoporus, plane, raceway, large-flange, little rib and large and small oil duct, adopt special fixture, the knife rest of lathe is improved, satisfy quality preceding, put, improve the processing benefit of product.Inner ring technology 2: overall height degree, the inside and outside chamfering of large-flange.Adopt special fixture to satisfy the product quality requirement.Outer ring technology 1: outer ring: car raceway, plane, external diameter, angle, the inside and outside road of non-basal plane.Outer ring technology 2: overall height degree, external diameter, the inside and outside chamfering of basal plane.
As preferably, described inner ring anchor clamps include clamping fixture seat, and clamping fixture seat is connected with the tensioner cover that can stretch into bearing inner race blank inside, and cross-under has clamp rod in the tensioner cover, and clamp rod connects cylinder, and the clamp rod end all is provided with the conical surface with the inwall that tensioner is overlapped.By cylinder pulling clamp rod, its conical surface is inner mobile at the tensioner cover behind the clamp rod rollback, thereby the tensioner cover is outwards opened, thereby clamps the bearing inner race blank.
Therefore, the present invention adopts numerical control that the inside and outside circle of bearing is machined, and finishes whole manufacturing procedures to inner ring, outer ring with 2 road technologies respectively, can play the effect of product size stability, and bearing is required can be lower, operation can not occur leaking, simple and reasonable for structure.
