Abstract
The utility model relates to a coil steel sleeve for fixing of a motor component. The coil steel sleeve comprises a steel sleeve body, a steel sleeve outer wall, a steel sleeve inner wall, and a steel sleeve top portion. The steel sleeve outer wall and the steel sleeve inner wall are in bottomless barrel shapes; the steel sleeve outer wall is sleeved at the periphery of the steel sleeve body and the steel sleeve inner wall is embedded into the center of the steel sleeve body; and the steel sleeve outer wall and the steel sleeve inner wall are concentrically arranged. Besides, the steel sleeve top portion is a circular ring connected to the outer edge of the steel sleeve inner wall. Compared with the prior art, the provided coil steel sleeve has the following beneficial effects: on the basis of structural improvement of the steel sleeve body, through hole arrangement optimization, and the through hole opening process, iron powder filling amount is increased, the product density contrast is reduced, and a problem of easy cracking of the product can be solved.
Description
Technical field
The utility model relates to the fixed motor part technical field, particularly a kind of coil steel bushing.
Background technology
As the coil fixed part of motor internal, coil steel sleeve structure complexity, part is more, thereby makes the part of mould also more, from the angle of producing, considers, and mould takes on the high side.
The outer wall of coil steel bushing, inwall and top thinner (1-2mm), the through hole that top arranges is in addition arranged irregular and adopts compressing, make the entity part volume less, product density distributes extremely inhomogeneous, causes top and outer wall, inwall easily to split, even come off.Coil steel bushing outer wall is different with inwall length, in the actual production debugging, is difficult to reach, and debugging in time, to revising size, still easily causes top and outer wall easily to come off.
The utility model content
The utility model purpose is to provide a kind of coil steel bushing, with solve coil steel bushing that employing iron powder of the prior art compacting forms due to the through hole skewness with, cause the entity part volume less, product density distributes extremely inhomogeneous, the technical matters that easily cause top and outer wall, inwall easily to split, even come off.
The utility model purpose is achieved through the following technical solutions:
A kind of coil steel bushing, for fixing of motor component, comprise the steel bushing body, steel bushing outer wall, steel bushing inwall and steel bushing top, described steel bushing outer wall and steel bushing inwall are bottomless tubbiness, described steel bushing outer wall is set in steel bushing body periphery, described steel bushing inwall is embedded in steel bushing body center, described steel bushing outer wall arranges with the steel bushing inwall is concentric, and wherein, the steel bushing top is the annulus that is connected to steel bushing inwall outer.
Preferably, described steel bushing body is provided with through hole, and those through holes comprise three circular holes and a profiled holes, and described circular hole size is smaller than profiled holes, adjacent one-tenth 90 degree of the straight line that these four through holes connect steel bushing inwall center.
Preferably, described circular hole adopts the bit bore mode to be opened on the steel bushing body, and described profiled holes adopts pressing mode to be opened on the steel bushing body.
Preferably, described steel bushing inwall and steel bushing top are made into integration, and steel bushing inwall and the side-looking of steel bushing top cross-section become L-type.
Preferably, it is compressing that described steel bushing body adopts iron powder.
Compared with prior art, the utility model has following beneficial effect:
1, a kind of coil steel bushing of the present utility model, the arranging of the architecture advances by the steel bushing body, through hole optimized and the hole opening technology of through hole, makes the charging quantity of iron powder increase, and the density contrast of product reduces, and the product easily problem of cracking is resolved;
2, the shape and structure of one-shot forming blank in the optimization of this body formed mould composition structure of coil steel bushing and actual production, also make conforming product rate greatly promote and the scrappage of product reduces greatly, and simultaneously, the processing of solid waste has also been optimized greatly.
The accompanying drawing explanation
Fig. 1 is coil steel sleeve structure figure of the present utility model;
Fig. 2 is coil steel bushing end view of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, further introduce the utility model.
Please refer to accompanying drawing 1-2, a kind of coil steel bushing, for fixing of motor component, comprise steel bushing body 1, steel bushing outer wall 2, steel bushing inwall 3 and steel bushing top 4, described steel bushing outer wall 2 and steel bushing inwall 3 are bottomless tubbiness, described steel bushing outer wall 2 is set in steel bushing body 1 periphery, and described steel bushing inwall 3 is embedded in steel bushing body 1 center, described steel bushing outer wall 2 and the concentric setting of steel bushing inwall 3, wherein, steel bushing top 4 is for being connected to the annulus of steel bushing inwall 3 outers; Described steel bushing body 1 is provided with through hole, and those through holes comprise three circular holes 5 and a profiled holes 6, and described circular hole 5 sizes are smaller than profiled holes 6, adjacent one-tenth 90 degree of the straight line that these four through holes connect steel bushing inwall 3 centers; Described circular hole 5 adopts the bit bore mode to be opened on steel bushing body 1, thereby the charging quantity of iron powder is increased, the density contrast of product reduces, circular hole 5 can be offered after the product global formation, when avoiding the pressing special-shaped hole, cause the problems such as fracture because product density is little, described profiled holes 6 adopts pressing mode to be opened on steel bushing body 1; Described steel bushing inwall 3 and steel bushing top 4 are made into integration, and steel bushing inwall 3 and the 4 cross section side-lookings of steel bushing top become L-type; Described steel bushing body 1 adopts iron powder compressing, has added in addition the better lubricant of lubricant effect in iron powder, thus the useful life of having improved mould.
Comprehensive above known to coil steel sleeve structure of the present utility model, coil steel bushing of the present utility model, the arranging of architecture advances by the steel bushing body, through hole optimized and the hole opening technology of through hole, make the charging quantity of iron powder increase, the density contrast of product reduces, and the product easily problem of cracking is resolved; In the optimization of this body formed mould composition structure of coil steel bushing and actual production, the shape and structure of one-shot forming blank, make conforming product rate greatly promote, and the scrappage of product reduces greatly, and the processing of solid waste has also been optimized greatly.
The utility model preferred embodiment is just for helping to set forth the utility model.Preferred embodiment does not have all details of detailed descriptionthe, and also not limiting this utility model is only described embodiment.Obviously, according to the content of this specification, can make many modifications and variations.These embodiment are chosen and specifically described to this specification, is in order to explain better principle of the present utility model and practical application, thereby under making, the technical field technical staff can utilize the utility model well.The utility model only is subject to the restriction of claims and four corner and equivalent.Above disclosed be only several specific embodiments of the application, but the application is not limited thereto, the changes that any person skilled in the art can think of, all should drop in the application's protection range.
