Abstract
The invention discloses a kind of commutators, it includes: commutator ontology and makees the copper segment of circumference arrangement in commutator ontology outer circle, the top of copper segment is equipped with ontology described in crotch and is equipped with chip-breaker, the crotch is trapezoidal, the commutator has broken off the risk jagged in smart car terminal, it in the service life for improving shaving tool simultaneously, plays upgrading and drops this advantages of.
Description
Technical field
The present invention relates to the fields of commutator topology, and in particular to and one kind is convenient for clamping, has been prevented in normal productive process,
The commutator for the risk that coiling hook is askew and spot welding point is inclined.
Background technique
Commutator is direct current generator, commutates as electric current on A.C. series motor, in order to allow motor persistently to turn
The component moved down, is commonly called as commutator, round, each touching being separately connected on rotor that commutator is that several contact chips surround
Head, two electrodes of outside connection are known as brush and contact, while only contacting two therein.Commutator is mainly used in electricity
On power driven tools, the Key Performance Indicator of commutator refers to its hypervelocity performance, and the high commutator of hypervelocity performance can guarantee to produce
Quality improves product service life.Has high hypervelocity performance, product first will have high mechanical strength, i.e. commutator
Bond strength between commutator segment and commutator ontology wants high.
In the prior art, mainstream commutator hook is straight hook, and hook global shape is rectangular, and working face is a cylinder
Face, for existing such commutator in motor assembling process, smart car commutator operation face easily generates burr in smart car terminal point；And
Straight hook commutator can generate hook by drawing malpractice danger in the winding process that motor assembles, and when point welding process, can generate hook point
Inclined risk.
Summary of the invention
Goal of the invention: in order to solve the deficiencies in the prior art, the present invention provides a kind of commutator, broken off at smart car end
Jagged risk when point, while the service life of shaving tool is improved, it plays upgrading and drops this advantages of.
Technical solution: in order to achieve the goal above, a kind of commutator of the present invention, it include: commutator ontology and
Make the copper segment of circumference arrangement in commutator ontology outer circle, the top of copper segment is equipped on ontology described in crotch and sets
There is chip-breaker, the crotch is trapezoidal.
As present invention further optimization, the size of the chip-breaker is width 0.9mm depth 0.1mm.
As present invention further optimization, the position of the chip-breaker is at crotch.
As present invention further optimization, the crotch is 96 ° -100 °.
The utility model has the advantages that a kind of commutator of the present invention has the advantage that compared with prior art
(1), increase chipbreaker structures on commutator operation face, play the smart car commutator operation face work in motor assembly
Sequence has broken off the risk jagged in smart car terminal, while having improved the service life of shaving tool, plays upgrading and drops this advantages of；
(2), the hook of commutator is made into trapezoidal hook, to reinforce the intensity of hook root；
(3), in assembling process, trapezoidal hook is regardless of all having prevented normal life in electric machine winding process or point welding process
During production, coiling hook is askew and spot welding point is inclined risk；
(4), the commutator of trapezoidal hook in production, is more advantageous on clamping to moulds of industrial equipment.
Detailed description of the invention
Fig. 1 is the structural diagram of the present invention；
Fig. 2 is top view of the invention；
Fig. 3 is the partial enlarged view of chip-breaker.
Specific embodiment
In the following with reference to the drawings and specific embodiments, the present invention is furture elucidated.
As shown in the picture, a kind of commutator of the present invention, it includes: commutator ontology 1 and outside commutator ontology 1
Circle makees the copper segment 2 of circumference arrangement, and the top of copper segment 2 is equipped with crotch 3, and the ontology 1 is equipped with chip-breaker
11, the size of chip-breaker 11 is width 0.9mm depth 0.1mm.The position of chip-breaker 11 is at crotch 3, in commutator operation face
Upper increase chipbreaker structures play the smart car commutator operation face process in motor assembly, have broken off jagged in smart car terminal
Risk, while improving the service life of shaving tool, play upgrading and drop this advantages of.
Crotch 3 is that trapezoidal, described crotch 3 is 96 ° -100 °, the hook of commutator is made into trapezoidal hook, to reinforce hook
The intensity of root, in assembling process, trapezoidal hook is regardless of all having prevented normal production in electric machine winding process or point welding process
In the process, the risk that coiling hook is askew and spot welding point is inclined, the commutator of trapezoidal hook in production, are more advantageous to clamping to moulds of industrial equipment
On.
The technical concepts and features of above embodiment only to illustrate the invention, the purpose is to allow be familiar with the technical field
Technical staff cans understand the content of the present invention and implement it accordingly, and can not limited the scope of the invention with this.All
The equivalent changes or modifications made according to spirit of the invention, should be covered by the protection scope of the present invention.
