Description
Technical field
The utility model is related to a kind of commutator assembly machine, more particularly to a kind of commutator divided rotating mechanism.
Background technology
Commutator is direct current generator, is commutated 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.In structure, it is round that commutator is that several contact chips surround, the connection of commutator bottom
Each contact on rotor, commutator side and brush contact.The operation principle of commutator is：After coil is by electric current, meeting
It under the action of permanent magnet, is rotated with repulsive force by attracting, when it is rotated with magnet balance, led to electric coil pair originally
The contact on commutator is answered just to be separated with brush, and brush is connected to the corresponding contact of that group of coil for meeting and generating motive force
On, it ceaselessly repeats down in this way, dc motor is just turned over.If the not effect of commutator, motor can only turn not
To half-turn with regard to stuck, electric brake can only be used as.
Currently, the commutator assembling post of engine commutator industry is the important link of commutator production, also just because it is tired
Difficulty is higher, so being still taking human as main assembling mode in the industry.Base components in engine commutator structure are copper
Type body part（Commutator segment）, it is in the structure with orderly cylinder packings, and insulating properties must be by cloud between copper body and copper body
Master slice is isolated, the copper type body part of bulk, mica sheet is loaded onto in group must be by plastic cement core（Make sizing to use）Support
And it is gradually arranged in cylindrical body, it necessarily requires operating personnel to the correct row of filling out of copper type body part, mica sheet in arrangement, i.e., will change
It is inserted into piece in the elongated slot of plastic cement core, then mica sheet is inserted between commutator segment one by one.During mica sheet is installed

In mouthful.
By using above-mentioned technical proposal, pusher dog position can be made to decline, so as to the lower wiring socle of pushing position.
Preferably, the pusher dog includes radix unguis and pawl point, and pawl point lower surface protrusion, which extends to, to be bonded in opening with mounting plate, pawl
Root thickness coordinates with straight slot height.
By using above-mentioned technical proposal, pusher dog can be limited, make pusher dog can only horizontal movement.
Preferably, be equipped with the mandrel rod vertical with mounting plate in the pusher dog sliding block, pusher dog close to one end of indexing cylinder with
Mandrel rod is pivotally connected.
By using above-mentioned technical proposal, make pusher dog can fine rotation, avoid making commutator big angle in its fall back process
Degree ground reversely rotates.
Preferably, the one side of the convex block towards indexing cylinder is pressed from both sides with pusher dog side into obtuse angle, and rounding off.
By using above-mentioned technical proposal, the thrust of the wiring socle in pusher dog fall back process to commutator can be reduced.
Preferably, it states mounting plate and is equipped with through-hole, through-hole and the commutator of positioning on a mounting board are concentric, are equipped in through-hole
The locating detent inside commutator can be extended to.
By using above-mentioned technical proposal, commutator can be positioned, be explicitly shown out processing stations, avoid commutator
It is detached from station.
Preferably, the projection of shape for falling within mounting plate upper surface of first notch is arc.
By using above-mentioned technical proposal, on the one hand facilitate processing, it on the other hand can be in the position-limiting action for ensureing clear opening
Under make clear opening largely expose.
In conclusion the utility model has the advantages that：
1. commutator can be made to rotate automatically, and accurate in place after rotation；
2. motion is ingenious, submission is smaller, and floor space is smaller, compact-sized.
