Abstract

The invention relates to a method for manufacturing a motor stator. The method comprises the following steps that: 1) stator iron sheets to be calculated are stacked fitly, and arranged in a sheet arrangement clamp to carry out sheet arrangement and compress; 2) after an upper clamp and a lower clamp are arranged, the sheet arrangement clamp is drawn out; 3) the upper clamp and the lower clamp which are filled with the stator iron sheets are put into an injection mould; 4) integral injection of a reel is carried out in the injection mould; 5) a stator iron core coated by the reel is taken out from the injection mould; and 6) finally, a stator coil is winded on the reel. The method has the advantages that the stator iron core is tightly coated by the integrally injected reel, thereby avoiding adverse influence on motor application caused by argon-arc welding or superposition and other fixed methods.

Description

A kind of method for manufacturing motor stator and anchor clamps thereof

Technical field

The present invention relates to the correlative technology field that motor is made, specifically a kind of method for manufacturing motor stator and be used for the anchor clamps of this method.

Background technology

The production of motor stator will sweep away next blocks of silicon steel sheet to punch press earlier, and is folded neat by certain quantity, rethinks way they are fixed into an integral body; Put the plastics drum stand respectively in the above and below of stator core then, between the upper and lower drum stand, also will fill up insulating cell; At last on drum stand around stator coil.

Fixing of stator core, adopt two kinds of methods at present:

A: argon arc welding

Argon arc welding can be welded together securely the stator silicon steel sheet, but the side effect that it brings but is to make to have formed magnet short-cut path between the silicon steel sheet, has reduced the effect of silicon steel sheet, makes the temperature rise of iron core increase;

B: folded riveting

Folded riveting is when utilizing progressive stamping, goes out several folded riveting buttons on every silicon steel sheet, and every punching press is once folded riveting a slice, forms an integral body at last.In folded riveting place, magnetic circuit is undergone mutation, and temperature is herein raise, and makes motor hot.

Summary of the invention

The purpose of this invention is to provide a kind of method for manufacturing motor stator, overcome the burning argon arc welding that the traditional stator iron core adopted fixedly the time and the existing shortcoming of method of folded riveting.

For achieving the above object, the present invention has adopted following technical scheme:

The invention discloses a kind of method for manufacturing motor stator, it is characterized in that comprising the steps:

1) the stator iron plate of counting is packed into after folded neat in the reason plate clamp, manage sheet and compress;

2) install and extract the reason plate clamp behind the lower clamp out;

3) the last lower clamp of stator iron plate will be housed, put into injection mold;

4) in injection mold, carry out the integral molded plastic of drum stand;

5) from injection mold, take out the stator core that has wrapped up drum stand;

6) last, on drum stand around stator coil.

Characteristics of the present invention are: adopt the drum stand of integral molded plastic, stator core is bundled together tightly, avoided the harmful effect that use causes to motor owing to use fixing meanss such as burning argon arc welding or folded riveting.

Embodiment

Below in conjunction with drawings and Examples the present invention is further described.

Please refer to Fig. 1 to shown in Figure 3, a kind of special fixture assembly, it comprises anchor clamps, lower clamp and the reason plate clamp between last anchor clamps and lower clamp,

The described anchor clamps of going up comprise anchor clamps front pressuring plate 1, go up jig main body 2 and go up anchor clamps rear fender 3, describedly go up anchor clamps front pressuring plate 1, go up jig main body 2 and upward anchor clamps rear fender 3 be connected and fixed by through hole 7 successively;

Described lower clamp comprises lower clamp front pressuring plate 4, lower clamp main body 5 and lower clamp rear fender 6, and described lower clamp front pressuring plate 4, lower clamp main body 5 and lower clamp rear fender 6 are connected and fixed by through hole 7 successively;

Described reason plate clamp comprises and compresses projection 8 and compress the compressed grooves 9 that projection 8 cooperates with described.The described projection 8 that compresses is fixed by screw 10 with compressed grooves 9.

Described reason plate clamp is mainly used in arrangement and compresses the stator iron plate 11 of bulk storage, promptly the stator iron plate is managed sheet, the groove size of the compressed grooves 9 among Fig. 4 and the size fit clearance of stator are very little, when the groove of compressed grooves 9 is put in the punching of stator successively, the all compacted groove 9 in the position of all around of stator piece has limited, stator iron plate 11 will fitly be arranged, because the stator piece of this moment is in loose state, all gapped between sheet and the sheet, the total height overrate need fall stator iron plate 11 and compress.See also Fig. 5,, compress projection 8 and compressed grooves 9 extruding stator iron plates 11, it is compressed by screw 10.

Concrete, please refer to shown in Figure 6ly, it comprises the steps: method for manufacturing motor stator

1) the stator iron plate is counted, obtained the stator iron plate of requirement;

Because folded thick the fixing of the stator iron plate of every kind of specification, after the thickness of silicon steel sheet is determined, its punching number is also determined, therefore, for the counting of stator iron plate, can adopt electronic scale to claim the weight of every groove stator: in a preferred embodiment, the thickness of stator is 70mm, silicon steel sheet thickness is 0.35mm, and the quantity of then every groove stator is the 70/0.35=200 sheet; Every stator piece weighs 1.2 grams, every groove stator weight=1.2*200=240 gram; Also can adopt the balance instrument to weigh: in a preferred embodiment, an end of balance is put 200 stator pieces, and the other end is put tested stator piece, and the same day, the stator number of tested end also reached 200 during average weighing apparatus;

2) the reason plate clamp of packing into of the stator iron plate 11 after will counting is managed sheet;

3) compressing projection 8 and the compressed grooves 9 stator iron plate after by 10 pairs of reasons of screw sheet is fixed and clamped;

4) install anchor clamps and fixing;

5) lower clamp and fixing is installed;

6) extract the reason plate clamp out;

7) the last lower clamp that fuses of stator iron plate 11 will be housed, put into injection mold;

8) in injection mold, carry out the integral molded plastic of drum stand 2;

9) from injection mold, take out the stator core 1 that has wrapped up drum stand 2;

10) last, on drum stand 2 around stator coil.

This method adopts the drum stand of integral molded plastic, and stator core is bundled together tightly, has avoided the harmful effect that use causes to motor owing to use fixing meanss such as burning argon arc welding or folded riveting.

Here description of the invention and application is illustrative, is not to want with scope restriction of the present invention in the above-described embodiments.Here the distortion of disclosed embodiment and change are possible, and the various parts of the replacement of embodiment and equivalence are known for those those of ordinary skill in the art.Those skilled in the art are noted that under the situation that does not break away from spirit of the present invention or substantive characteristics, and the present invention can be with other forms, structure, layout, ratio, and realize with other elements, material and parts.
