Description

A kind of split type core structure

Technical field

The utility model belongs to motor stator manufacturing field, refers in particular to a kind of split type core structure.

Background technique

Traditional motor is using monoblock type iron core winding coil or using the work of embedded groove again after winding former coiling Coiling mode in skill scheme, especially external stator, often production efficiency is low, and copper factor is low, the process time is long, leverages The fabrication cycle and processing cost of motor.Kinds of schemes solution, such as straight strip type are proposed for this phenomenon both at home and abroad at present, Coiling after iron core is unfolded, shrink welded again after the completion of coiling, but it shrinks and welding operation has difficulty in process, and welded bands The heat release come be easy to cause iron core to deform, and for another example uses common split type iron core, separates coiling again using welding, extruding Etc. techniques close up iron core, but equally have

Welding squeezes the puzzlement that will cause iron core deformation, and the cost of technology is expensive.

Utility model content

The purpose of the utility model is to provide a kind of long service life, low in cost, easy to assembly, split type iron core knot Structure.

Purpose of the utility model is realized as follows:

A kind of split type core structure, includes split type punching group and iron core frame, the side of the split type punching group around There is coil, inserting groove is equipped in the iron core frame, the side of the split type punching group is equipped with to be adapted with the inserting groove Plug division, iron core frame side forms the retaining ring at least two punching groups described in axial restraint.

Preferably, the inserting groove is using the design of " work " word, and the iron core frame is using tubbiness formula structure.

Preferably, the outer ring of the retaining ring and the iron core frame uses the design of same diameter, and the retaining ring is fixed on One end of the iron core frame.

Preferably, installation card slot is equipped in the inserting groove facilitates the punching group to match with the iron core frame.

Compared with the prior art, the utility model has prominent and beneficial technical effects that:

1. the utility model uses split type structure, and uses proprietary structure --- fixed split type punching group from And the techniques such as traditional welding are replaced, it is simple, convenient and safe and reliable.

2. the utility model iron core frame uses the structure of tubbiness, the risk of welding deformation between punching group can be reduced, from And punching is avoided to connect the unreliable risk in turn resulting in magnetic field open circuit.

3. the retaining ring in the utility model can play position-limiting action, punching group is prevented to be pressed into this excessive phenomenon when installing Occur, and it is firm to guarantee that split type punching group is connected with iron core frame.

Specific embodiment

The utility model is described further with specific embodiment below.

As shown in Figure 1-3, a kind of split type core structure, described split type comprising split type punching group 1 and iron core frame 2 The side of punching group 1 is wound with coil, is equipped with inserting groove 21 in the iron core frame 2, the side of the punching group 1 be equipped with it is described The compatible plug division 11 of inserting groove 21, the inserting groove 21 is using the design of " work " word, and the iron core frame 2 is using tubbiness formula knot Structure, 2 side of iron core frame are equipped with the retaining ring 3 at least two iron cores described in axial restraint, when user needs coiling Punching group when installing to iron core frame 2, using compatible plug division 11 and inserting groove 21, and the iron core be preferably punching or May be more preferable with material iron plate etc., enable each split type punching group simply fixed and become wound stator, simultaneously Iron core frame 2 is integrally formed casting using with retaining ring 3, and punching group 2 can be directly directly installed in iron core frame 2 by user, and be had Effect is fixed.The techniques such as traditional welding are replaced using the fixed split type iron core of application specific architecture, it is more traditional more simple in operation, and Securely and reliably.

The utility model is further arranged to, outer ring the setting using same diameter of the retaining ring 3 and the iron core frame 2 Meter, and the retaining ring 3 seals one end of the iron core frame 2.Retaining ring 3 and iron core frame 2 use identical diameter, make to match when its installation It closes more accurate, and effectively prevent the punching group of coiling to be pressed into excessive this phenomenon and occur.

As shown in figure 4, the utility model is further arranged to, it is equipped with installation card slot 22 in the inserting groove 21 and facilitates punching Group 1 is matched with the iron core frame 2.After mounting, mounting groove 22 can play prevents punching group 1 from falling to user, to make whole The service life is longer for a iron core group.

Above-described embodiment is only the preferred embodiment of the utility model, not limits the protection model of the utility model according to this It encloses, therefore: the equivalence changes that all structures, shape, principle according to the utility model are done should all be covered by the protection of the utility model Within the scope of.
