The invention discloses a kind of processing method of commutator, comprise the steps: that pedestal is made in injection moulding, pedestal one end face has the first projection that decile is arranged, other end has and the first projection the second projection one to one; Inside the first projection, car goes out one annular groove; Go out the hole of mating with the second projection in the punching of commutator segment one end, mill out two flutings at the commutator segment other end, make this end of commutator segment be divided into mid portion and two side portions; Bending two side portions is hook-shaped; The unci of commutator segment one end is inserted in annular groove, the first projection is placed between two two side portions, and bend the other end and make in the second projection access aperture; Repeat the operation of previous step until pedestal is covered with commutator segment; The both ends of the surface of pedestal are covered with binding material; The mid portion solidifying palintrope folding commutator segment one end at binding material forms wiring crotch; Installing hole is gone out at the center car of pedestal; Cleaning polishing.This method processing commutator is easier, and cost is lower.
Description
Technical field
The present invention relates to a kind of processing method of commutator.
Background technology
Commutator is parts very important in motor.The mode of screening injection moulding that what the processing method of current commutator adopted usually is, by commutator segment and mica sheet staggered on screening core, then insert injection mo(u)lding in mould.The commutator that this processing method is produced has comparatively superior flat quality, but this processing method operation easier is large, and cost is high.
Summary of the invention
For the deficiencies in the prior art, the problem to be solved in the present invention is to provide a kind of more simple and processing method of the commutator that cost is lower.
For this reason, the present invention realizes in the following way: a kind of processing method of commutator, it is characterized in that comprising the steps:
(1) cylindrical base is made in injection moulding, pedestal one end face has the first projection that decile is arranged, other end has and the first projection the second projection one to one;
(2) inside the first projection, car goes out one annular groove;
(3) take copper material as raw material punching commutator segment;
(4) go out the hole of mating with the second projection in the punching of commutator segment one end, mill out two symmetrical flutings at the commutator segment other end, make this end of commutator segment be divided into the two side portions of a mid portion and two;
(5) it is hook-shaped for bending two side portions;
(6) unci of commutator segment one end is inserted in annular groove, the first projection is placed between two two side portions, and bend the other end and make in the second projection access aperture;
(7) operation of step (6) is repeated until pedestal is covered with commutator segment;
(8) in the both ends of the surface of pedestal, binding material is covered with;
(9) solidify palintrope folding mid portion at binding material and form wiring crotch;
(10) installing hole is gone out at the center car of pedestal;
(11) cleaning polishing.
In step (4), the spacing of two two side portions is mated with the width of the first projection.
In step (6), the unci of commutator segment one end is inserted after in annular groove, punching press unci diametrically.
In step (8), after binding material solidifies, the adhesion layer that binding material is formed is polished.
In the processing method of this commutator provided by the invention, its each step can both adopt conventional equipment to operate, and compares the processing method of the screening injection moulding in tradition, operate easier, and cost is lower.

Embodiment
The processing method of this commutator, comprises the steps:
(1) cylindrical base 5 is made in injection moulding, pedestal 5 one end face has the first projection 9 that decile is arranged, other end has and the first projection 9 second projection 2 one to one;
(2) inside the first projection 9, car goes out the annular groove 11 in one radial direction;
(3) take copper material as raw material punching commutator segment 1;
(4) go out the hole 12 of mating with the second projection 2 in commutator segment 1 one end punching, mill out two symmetrical flutings 13 at commutator segment 1 other end, make this end of commutator segment 1 be divided into the two side portions 10 of a mid portion 8 and two;
(5) two side portions 10 is bent in hook-shaped;
(6) unci of commutator segment 1 one end is inserted in annular groove 11, the first projection 9 is placed between two two side portions 10, and bend the other end and make in the second projection 2 access aperture 12;
(7) operation of step (6) is repeated until pedestal 5 is covered with commutator segment 1;
(8) in the both ends of the surface of pedestal 5, binding material is covered with;
(9) binding material solidify palintrope folding commutator segment 1 one end mid portion 8 form wiring crotch;
(10) installing hole 6 is gone out at the center car of pedestal 5;
(11) cleaning polishing.
Wherein, in order to commutator segment 1 is convenient when being arranged on pedestal 5, also more firm in order to make commutator segment 1 be arranged into after on pedestal 5, in step (4), the spacing of two two side portions 10 is mated with the width of the first projection 9.Like this after the first projection 9 passes two two side portions 10, the first projection 9 is just stuck between two two side portions 10, can fully for commutator segment 1 provides spacing firm effect.
In order to make the unci of commutator segment 1 end more fit pedestal 5, and strengthen the bonding strength of commutator segment 1 and pedestal 5, in step (6), the unci of commutator segment one end is inserted after in annular groove 11, punching press unci diametrically.
In order to reduce the frictional dissipation of commutator in rotation process, in step (8), after binding material solidifies, the adhesion layer 8 that binding material is formed is polished.
