The invention has the beneficial effects as follows: be provided with annular knurl in one end of rotating shaft, knot when fan blade coordinates with rotating shaft can be increased
Close intensity；Meanwhile, it is provided with inserts, and inserts is embedded in fan blade, when can be assembled with rotating shaft by inserts regulation fan blade
Concentricity, thus noise when reducing use, reduce rocking during using, and improves service life.The fan of this invention
Device, without using casing to coordinate location with fan blade, simplifies assembling procedure, saves case material, reduces cost.
In some embodiments, inserts is rounded, is provided with circular hole in the middle of inserts, and the internal diameter of circular hole is more than outside rotating shaft
Footpath.Thus, inserts is facilitated to be set in rotating shaft.
In some embodiments, fan blade is moulding.Thus, it is simple to the molding of fan blade, and be easy to inserts to fan blade
Regulation with rotating shaft concentricity.
In some embodiments, the thickness of inserts is 1～1.5mm.Thereby it is ensured that the service behaviour of fan blade, meanwhile,
Save the material cost of inserts, add the intensity of fan blade simultaneously, improve service life.
According to another aspect of the present invention, it is provided that the processing method of a kind of said fans device, comprise the steps:
A, rotating shaft one end annular knurl after, one end and the inserts of rotating shaft are fixed in injection mold；
B, being molded in injection mold, injection mo(u)lding obtains fan blade.
The processing method of the fan assembly of the present invention provides the benefit that: one end and the inserts of rotating shaft are fixed on injection mould
In tool, the perpendicularity of rotating shaft and inserts by the location of mould, can be revised；In injection mold, carry out injection mo(u)lding again obtain
Fan blade so that inserts can be embedded in fan blade, simultaneously, it is ensured that one end of rotating shaft and fan blade fixing compact, and have very well
Concentricity, it is ensured that when rotating shaft drives fan blade to rotate, stationarity is high, reduces noise, improves service life.This processing method,
Manufacturing process is simple, reduces the workload of Producer, compared with prior art, saves case material, reduce cost.
In some embodiments, the injection temperature in step b is 225～275 DEG C.Thereby it is ensured that the injection of fan blade
The stability of the performance in molding, and fan blade.
In some embodiments, the injected plastics material of fan blade is PBT material.Thus, PBT material is used, it is ensured that wind
The intensity of leaf.
In some embodiments, inserts is ferrous material.Thus, this inserts is used to combine with PBT material, Ke Yiyou
The solution of effect ejects, because of cold and hot contraction distortion and the die sinking of PBT material self, the disqualification rate causing deformation to be caused, and improves
Production efficiency.

Detailed description of the invention
The present invention is further detailed explanation below in conjunction with the accompanying drawings.
With reference to Fig. 1, Fig. 2, Fig. 3 and Fig. 4: fan assembly, including fan blade 1, rotating shaft 2 and inserts 3, one end of rotating shaft 2 is provided with
Annular knurl 4, fan blade 1 is set in one end of rotating shaft 2, and inserts 3 is set in outside rotating shaft 2, and is embedded in fan blade 1.Rotating shaft 2 one end
Annular knurl 4 is Fructus Ananadis comosi shape decorative pattern, adds fan blade 1 when being molded in rotating shaft 2 one end, the compactness that both combine, it is ensured that Liang Zhelian
The steadiness connect.
Wherein, fan blade 1 is moulding, and the thickness of inserts 3 is 1～1.5mm, preferably 1mm.
Inserts 3 is rounded, is provided with circular hole in the middle of inserts 3, and the internal diameter of circular hole is more than the external diameter of rotating shaft 2.This circular hole of inserts 3
The multiple aperture of circumferential distribution, it is simple to fan blade 1 is when injection, and inserts 3 positions with fan blade injection mold, is conveniently repaiied by injection mold
Positive rotating shaft 2 and the perpendicularity of inserts 3, and then, improve fan blade 1 and the concentricity of rotating shaft 2 after injection.
The fan assembly of the present invention, strengthens the intensity of fan blade 1, meanwhile, at inserts 3 outer injection mo(u)lding wind by inserts 3
Leaf 1 so that after ensure that the inserts 3 perpendicularity with rotating shaft 2, it is achieved that rotating shaft 2 is high with the concentricity of fan blade 1, degree of balance
Good purpose.
In use, the other end of rotating shaft 2 is connected the fan assembly of the present invention with the output shaft of motor, by motor
Rotating and drive rotating shaft 2 to rotate, rotating shaft 2 drives fan blade 1 fixed thereon to rotate, and during rotation, stationarity is high.
The processing method of said fans device comprises the steps:
A, rotating shaft 2 one end annular knurl after, one end and the inserts 3 of rotating shaft 2 are fixed in injection mold, injection mold install
On injection machine；Thus, by the perpendicularity of injection mold correction rotating shaft 2 with inserts 3；
B, being molded in injection mold, injection mo(u)lding obtains fan blade 1.Injection machine is gradually heating to 225～275 DEG C,
And be molded, injected plastics material is gradually filled with injection mold, and is tightly combined with one end and the inserts 3 of rotating shaft 2.
The injected plastics material of fan blade 1 is PBT (polybutylene terephthalate, i.e. polybutylene terephthalate
Ester) material, PBT material is a kind of tough and tensile engineering thermoplastic material, has extraordinary chemical stability, and mechanical strength, electricity are absolutely
Edge characteristic and heat stability, have good insulating properties.
Inserts 3 is ferrous material.
After fan blade 1 has been molded, it is gradually cooling to room temperature, die sinking, and with thimble, fan blade 1 is ejected, this fan assembly
Production completes.
The fan assembly obtained is produced, by the common effect of inserts 3 with mould by the processing method of this fan assembly
Ensure that rotating shaft 2 and the concentricity of fan blade 1 and degree of balance, after injection mo(u)lding, rotating shaft 2 coordinates with fan blade 1 closely, it is not necessary to use
Casing coordinates with fan blade and realizes coordinating of rotating shaft and fan blade, decreases the material materials of casing, reduces material cost.This processing
Method, by completing the assembling of rotating shaft 2 and fan blade 1 after injection, improves production efficiency, greatly reduces workload, decrease
Cost of labor.
Above-described is only the preferred embodiment of the present invention, it is noted that for those of ordinary skill in the art
For, without departing from the concept of the premise of the invention, it is also possible to make some deformation and improvement, these broadly fall into the present invention
Protection domain.
