Description
Technical field
The utility model relates to the flabellum central spindles of radiator fan, are a kind of flabellum central spindle riveted constructions of radiator fan.
Background technique
Radiator fan is generally primarily referred to as mainboard devices cooling fans such as CPU, video cards, and main purpose is will be hot
Amount transfers out comes and blows near air in, achieve the effect that cooling, some of radiator fans be applied to electrical cabinet or
In industrial equipment cabinet.Such radiator fan is equipped with flabellum generally in frame, and coil, current existing industry axis are equipped in flabellum
The mode of core implantation rotor (flabellum) mainly has central spindle to be implanted directly into, copper sheathing riveted central spindle or iron set riveted central spindle are implanted into three kinds of sides
Formula, aforesaid way, which requires rotor plastic cement mode, can just further fix, and wherein it is simple to be implanted directly into rotor plastic structure for central spindle；
Then two kinds of implantations, wherein former needs worked copper external member to carry out jig technique for riveting again, therefore processing technology is complicated, process
More, fit dimension precision is high, and low efficiency is at high cost；Latter approach is only adjusted on material, except unit price slightly reduces
Outside, other weakness are same as above, and binding force does not reach requirement on central spindle reinforcement process, and structural strength is at laterally longitudinal both ends
It dies down, there are biggish hidden danger after injection molding flabellum.
Summary of the invention
To overcome above-mentioned deficiency, the purpose of this utility model is that a kind of flabellum central spindle riveting of radiator fan is provided to this field
Structure is closed, solving it in existing similar product, the design of flabellum axle core riveted construction is not good enough, and stability and service life is caused to have
The technical issues of influence.The purpose is to what is be achieved through the following technical solutions.
A kind of flabellum central spindle riveted construction of radiator fan, the central spindle of the flabellum central spindle riveted construction and the motor slot of flabellum
Interior centre bottom is linked together, and centre bottom outside bottom surface is rotor glue position in the motor slot of flabellum；Its structure designing points is
The central spindle and flabellum junction are equipped with zinc alloy piece, i.e. the ringlet platform center of the blowout patche slot of shaft one end and zinc alloy piece one end
Slot die casting fastens, and the central channel is central spindle fluting, and the other end of zinc alloy piece is equipped with great circle disk, the central spindle being linked together and zinc
Alloy components and flabellum integrated injection molding.The above-mentioned flabellum central spindle riveted construction reinforces central spindle scheme using die casting, by central spindle
It is implanted into mold and carries out die casting, so that central spindle and zinc alloy piece is fixed in the form of die casting, work of the zinc alloy piece in die casting
Central spindle is combined under skill, die casting central spindle part increases demand of the integral rotor (flabellum) to transverse structure intensity in design, and
Demand to vertical structure pulling force.
The blowout patche slot internal-and external diameter of the central spindle is equipped with annular knurl line, and the great circle dish external diameter edge of zinc alloy piece is equipped with outer gear ring.
Above structure makes central spindle and zinc alloy piece, and further fixing between zinc alloy piece and flabellum further enhances its structural strength.
The zinc alloy piece is molded in the motor slot of flabellum in centre bottom boss slot, and convex is equipped in boss slot
Platform and outer ring recess.The components such as the electrical-coil that above structure is convenient in flabellum further fix.
The structure design of the utility model is reasonable, has high intensity, and low cost, the service life is long, and stability is good, is convenient for automatic metaplasia
The characteristics of production, and operating efficiency is effectively improved while cost is reduced, cost of labor is saved, structural strength is simultaneously
It is improved, improves the competitive advantage of complete product；It is suitable as flabellum and central spindle in radiator fan and is combined into flabellum
The production and application of rotor and the structure of similar product are improved.

Specific embodiment
Now in conjunction with attached drawing, the utility model structure and use are further described.As Figure 1-Figure 4, the flabellum axle
The central spindle 2 of core riveted construction is linked together with centre bottom in the motor slot of flabellum 1, in the motor slot of flabellum on the outside of centre bottom
Bottom surface is rotor glue position；Its specific structure is as follows: central spindle and flabellum junction are equipped with zinc alloy piece 3, the i.e. blowout patche of shaft one end
The 301 central channel die casting of ringlet platform of slot 201 and zinc alloy piece one end fastens, and the central channel is that central spindle is slotted, inside and outside blowout patche slot
Diameter is equipped with annular knurl line, and the other end of zinc alloy piece is equipped with great circle disk 302, and great circle dish external diameter edge is equipped with outer gear ring, is linked together
Central spindle and zinc alloy piece and flabellum integrated injection molding.Meanwhile zinc alloy piece is molded in center in the motor slot of flabellum
In bottom boss slot 101, inner convex platform and outer ring recess are equipped in boss slot.To the electrical-coil with circuit board by hoop buckle ring,
The components such as precision bearing are inserted in the axle sleeve outer diameter of fan outline border, the central spindle in the axle sleeve flabellum of fan outline border, and the place of being correspondingly connected with adds
Enter fixed glue for fixing, which can be used in similar radiator fan.
The prioritization scheme of the utility model makes the structural enhancing of rotor (flabellum) to reach design requirement, structural strength
Reach 2-3 times of former reinforcing mode, because technique is die casting, product size precision is high, cooperates without more part sizes, mold
Die casting operation effectively improves efficiency, and realizes board automation, has saved cost of labor, original is reduced in terms of unit price
There is the one third of mode, is suitable for high revolving speed long-life fan.
