Description
Technical field
It is particularly a kind of to wider width, the more complicated spherical outside surface in type face the present invention relates to a kind of metal cutting process cutter
The convex spheroid machining combination forming cutter of needle roller spherical bearing processing.
Background technology
Because needle roller spherical bearing is simple in construction, large carrying capacity, structure type strong adaptability, therefore it is various at home and abroad
In machinery, particularly high-end vehicles and precise machining equipment, aircraft, superior automobile, the driving of motorcycle, steering increasingly
Kind of bearings is widely used.
Because the spherical outside surface of needle roller spherical bearing is more complicated, hardly possible processing, typically carried out using combination forming cutter disposable
Processing, but the maximum machining width of existing domestic and international molding cutter is no more than 20 millimeters, can't process larger needle roller spherical axis
Hold, the processing to big needle roller spherical bearing, existing enterprise have to use simple forming cutter progress extension set bed, operation break-down to add step by step
Work, when as a result causing enterprise's progress product development again, disposable input is very big.Simultaneously because extension set bed, operation break-down exist it is secondary or
Multiple clamping, and cause size unstable and the harmful effect of tolerance stack, and at each processing transition face, also easily exist
Transition shoulder or wedge angle, the fraction defective of product, scrappage is caused to rise.
Cutter inside and outside a kind of open coaxial setting-in of the patent No. 201720018591.4 " combination forming knife ", a synchronous forming
Cylinder inside and outside processing, it is high in machining efficiency, cost is low, it is mainly used in the inside and outside processing of automobile metal part.
Number of patent application 201410441526.3 " a kind of combination forming knife " discloses a kind of for processing power transmission shaft and hair
The combination forming knife of motivation cooler support, the one-shot forming of die cavity holes in realization, avoid changing different cutters being processed and make
Into the problem such as machining accuracy is low.
The content of the invention
The technical problems to be solved by the invention are：A kind of convex spheroid machining combination forming cutter is provided, cutter structure closes
Reason, rigidity is strong, stability is good, service life length, with its converted products, substantially increases product stability and qualification rate, and
Production cost is reduced, it is cost input by new product development to greatly reduce enterprise.
Technical scheme is used by the present invention solves the above problems：Convex spheroid machining combination forming cutter, including blade,
Knife bar, the blade both ends are symmetrical, and one end abrasion interchangeable uses, and blade is oblique by middle Roound edge and Roound edge both sides
Face blade and the vertical plane of two edges composition, the knife bar are combined into one by front bar and rear bar, and the blade is inserted repeatedly in knife
Integral, the front end face of the front bar and shape, the size of blade front and rear end are fixed in the front bar of bar and with pressing plate and screw
Match.
Compared with prior art, the advantage of the invention is that：Convex spheroid machining combination forming cutter, 1, will be original multiple
Simple forming cutter, design, Multitest and the bulge test such as cutter compacting, processing, just optimize and combine into through public relations, cutter die
The combination forming knife of the disposable processed complex spherical outside surface of energy, and the forming cutter width after optimization can reach 25 millimeters, more than existing
Have and use 20 millimeters of sintex width maximum limit both at home and abroad, expand use range, meet that user requires, 2, outside
Between the arc surface of sphere and outer chamfering, a transition arc is designed, is used for the indent for processing needle roller spherical bearing spherical outside surface herein
Small arc-shaped, thoroughly eliminate because of step surface caused by operation break-down processing, avoid the generation of burr.3rd, blade both ends are symmetrical, one end
Other end interchangeable uses after abrasion, and blade, which is fully used, also extends service life.4th, using Assembled cutter to rolling
Pin spherical bearing carries out disposable Vehicle Processing, and original need to divide three chassis beds to complete the processing of spherical outside surface, substantially reduce enterprise and open
The cost of new product input is sent out, and is thoroughly eliminated because of the secondary or multiple clamping of extension set bed, operation break-down processing, caused size is not
Stable and tolerance stack causes the accumulated error influence on product, so as to improve the stability of product, yield rate, with being combined into
Type cutter needle roller spherical bearing is machined than prior art milling machine process it is simple, also reduce production cost.Except use
In outside the processing of complicated needle roller spherical bearing spherical outside surface, it may also be used for all processing with spherical outside surface product.

Fig. 2, the present invention explosive view.
Fig. 3, the present invention use state reference chart.
Embodiment
Embodiments of the invention are further described below in conjunction with the accompanying drawings.
There is installation screw 22. entirety that knife bar 2 is combined into by front bar 21, rear bar 23, rear bar upper surface front end
The front end face two edges of front bar 21 are straight plane 213, the middle arc surface 212 for the contour line 211 of band two, upper surface both sides
For inclined-plane 214, the height of front bar 21 is less than rear bar 23, and front bar adds blade height equal to the height of rear bar.
1 forward and backward both ends of the surface of blade are symmetrical, and after blade long-term use one end abrasion, under being dismantled from knife bar 2, u-turn is again
Use, make full use of blade material, also extend the service life of blade.
The two edges of the front end face of blade 1 are vertical plane 11, and center section is Roound edge 13, the Roound edge of circular arc
13 both sides are beveled edge 12, the rounding off of Roound edge 13 of beveled edge 12 and circular arc, arrange and cut groove 14 by 12 degree
Inclined-plane and the small arc-shaped that radius is 3 millimeters form.
By blade 1 insert repeatedly installed in knife bar front end front bar 21 on, above blade again with pressing plate 3 push down forward and backward bar 21,
23, pressing plate 3 is fixed on knife bar 2 by screw 23 with screw 4, forms combination forming cutter, as shown in Figure 1 and Figure 2.
In use, knife bar 2 is screwed on lathe knife-frame table 7, it is to be processed by oil cylinder pushing knife rest platform 7
The outer ring 5 of part needle roller spherical bearing is clamped on the chuck 6 of lathe, is rotated with machine spindle speed, oil cylinder pushing knife rest platform
7, the blade on blade 1 carries out spherical arc turnery processing to the outer ring 5 of needle roller spherical bearing.At this moment iron filings cut groove 14 toward row
Put discharge.Oil cylinder pushing knife rest platform during preceding 8 position of limit switch to after stopping turning, after again returning to the rear position of limit switch 9
Stop.Next circulation is carried out again.
Process the corresponding straight line plane 53 with angle to needle roller spherical bearing, the small arc surface 52 of one section of indent,
The great circle cambered surface 51 of one section of evagination forms the arc-shaped surface to smoothly transit, as shown in Figure 3.
And great circle cambered surface 51 matches with Roound edge 13, beveled edge 12 and the phase of straight line plane 53 with angle
Match somebody with somebody, shape, size match, i.e. front and rear end shape, the size of the front end face of front bar and blade 1 match.
Similarly, also can be simple to operate to being machined with spherical outside surface product with this combination forming cutter, use model
Enclose wide.
