Abstract
The utility model relates to a flange bell housing blank which comprises a blank body. The flange bell housing blank is characterized in that the blank body is cylindrical, the overall length of the blank body is larger than the double of that of two flange bell housings, the contours of the two flange bell housings are symmetric about a middle line, a flange blank is arranged in the middle of the outer circumferential surface of the blank body, and the thickness of the flange blank is more than the double of the sum of the flange thickness and the end width. The flange bell housing blank is reasonable in structure and convenient to machine and can be machined and produced by a universal bell housing device, manufacturing cost is reduced, and productivity can be improved.
Description
Technical field
The utility model relates to a kind of blank, especially relates to a kind of CV joint for car fixed end flange outer race blank.
Background technique
Outer race is the strength member of constant velocity universal joint fixed end, for connecting automotive wheel and constant velocity driving shaft, due to structural requirement, to be connected with road wheel end by the hole on flange plate with automotive wheel, therefore for the production of common outer race equipment, because equipment size reason is very difficult, produce flange plate type outer race, the for example punching press in traditional outer race moulding way (as " processing technology of a kind of outer race drift and outer race " (publication No.: CN102671989A)), forge (" Forging Technology of outer race " (publication No.: CN103252434A)) and all have limitation, need to customize large-scale equipment produces, or when being designed, flange blank increases clamping position, can cause product weight to increase and cost rising.
Summary of the invention
The utility model main purpose is to provide a kind of flange outer race blank, and it can carry out processing with general outer race equipment, is easy to processing, and precision is higher.
The above-mentioned technical problem of the utility model flange outer race blank is mainly solved by following technical proposals: flange outer race blank, comprise blank idiosome, it is characterized in that: blank idiosome is cylindric, more than total length is greater than the twice of two flange outer race total lengths, two flange outer race profiles are symmetrical arranged with medium line; In blank idiosome outer circumferential face neutral position, blank flange is set, blank flange thickness is more than the twice of flange thickness and end width sum.This structure, rational in infrastructure, be convenient to processing, can carry out processing manufacture with general outer race equipment, reduce manufacture cost, be also convenient to boost productivity.
As preferably, at the end face of blank idiosome side a and b, several projections are set, and the projection at two ends one by one corresponding, with blank idiosome medium line, be symmetrical arranged; On end face, each bump array is circle distribution, and consistent with each interior raceway groove circle distribution.This structure, is convenient to add and is easy to man-hour to make the interior raceway groove at two ends all to keep circumferential position precision with flange hole, further reduces manufacture difficulty and manufacture cost.As preferably, in the middle part of blank idiosome, establish central through bore.Reduce following process amount, reduce manufacture cost.
Therefore, the utility model flange outer race blank forming method has lower processing cost, is easy to realize batch production, and product can keep higher precision, and has good conformity.
That the utility model flange outer race blank has is rational in infrastructure, be convenient to processing, can reduce costs.

Embodiment
Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment: the utility model flange outer race blank, as shown in Figure 1, comprise blank idiosome 1, it is characterized in that: blank idiosome 1 is for cylindric, more than total length is greater than the twice of two flange outer race 101 total lengths; In blank idiosome 1 outer circumferential face neutral position, blank flange 2 is set, blank flange 2 thickness are more than the twice of flange 102 thickness and end 107 width sums.
End face at blank idiosome 1A end and B end arranges several projections, and the projection at two ends one by one correspondence, with blank idiosome 1 medium line, be symmetrical arranged; On end face, each bump array is circle distribution, and consistent with each interior raceway groove 104 circle distribution.
Two flange outer race 101 profiles are symmetrical arranged with medium line 5; Central through bore is established at blank idiosome 1 middle part.
During moulding, as shown in accompanying drawing 1, accompanying drawing 2, accompanying drawing 3, accompanying drawing 4, accompanying drawing 5, blank idiosome 1 is made as to two flange outer races 101 with the relative profile in end 107, and leaves machining allowance in neutral position, carry out thereafter cutting; Add man-hour, with end face 3 and the cylindrical 4 of blank idiosome 1A end, carry out clamping and positioning, flange 102, periphery and upper annular groove 103 thereof, inner ball surface 105 and the each and interior raceway groove 104 of processing B end; Again with B end end face and the cylindrical of blank idiosome 1 carry out clamping and positioning thereafter, periphery and upper annular groove 103, inner ball surface 105 and the through hole of processing A end, the mode of cutting processing to wash process each interior raceway groove 104 to each interior raceway groove 104 top curve in same sphere, process afterwards each flange hole 106, take center line 5 as point of division, cutting in the middle of blank idiosome 1 is disconnected again.End face at blank idiosome 1A end and B end arranges several projections, and the projection at two ends one by one correspondence, with blank idiosome 1 medium line, be symmetrical arranged; On end face, each bump array is circle distribution, and consistent with each interior raceway groove 104 circle distribution; Adding man-hour, the projection of holding take A end, B, as circumferential benchmark, is processed each interior raceway groove 105, reprocesses each flange hole 106.
Outer race is the strength member of constant velocity universal joint fixed end, connect automotive wheel and constant velocity driving shaft, due to structural requirement, to be connected with road wheel end by the hole on flange plate with automotive wheel, therefore for the production of common outer race equipment, because equipment size reason is very difficult, produce flange plate type outer race, need to customize large-scale equipment and produce, or increase clamping position when flange blank is designed, can cause product weight to increase and cost rising.
The utility model can address the above problem, and can carry out processing with general outer race equipment, can't gain in weight and cost, is easy to realize batch production.Adopt above structure, the utility model, compared with conventional blank, has the following advantages:
Can alleviate a product blank weight, and can process with standard equipment, and can guarantee the accuracy of manufacturing of product, a blank can be produced two products simultaneously simultaneously, has improved manufacturing efficiency, has reduced cost of production, and product is easy to realize.
