Description
Technical field
The utility model is related to a kind of step commutator copper shells.
Background technology
The manufacturing process of micro-motor commutator mainly includes the processes such as base, cold extrusion, pressure injection resin, crotch, groove milling,
In above-mentioned process, due to the backwardness of mold so that in process many processes need worker manually complete or certain
A process needs more molds that could realize so that low production efficiency and quality it is difficult to ensure that, it is each to commutator along with lacking
The research of relationship between modular construction and overall performance so that the overall quality of commutator fails to increase always.Traditional volume
Board-like commutator is in curved outer hook, generally by use four decompressors, the angle of taper of the staking punch of every decompressor
It tapers into so that the outer hook above copper sheathing is finally vertical with copper sheathing wall increasingly towards outer incline, and this processing technology, which exists, to be accounted for
With the shortcomings of equipment is more, Ren Yuanduo, labor intensity are big, processing efficiency is not high.
Utility model content
Above-mentioned to solve the problems, such as, the purpose of this utility model is to provide a kind of step commutator copper shells.
The step commutator copper shell, is provided with centre bore and convex ribs item, injects phenolic moulding powder in process, play support copper
Shell prevents the effect of copper shell film flying, improves product qualification rate, reduces production cost, on the other hand, is molded staircase structural model
Compared to the turnery processing that the prior art eliminates outer circle step, production efficiency is improved.
In order to achieve the above objectives, the technical solution of the utility model is：
A kind of step commutator copper shell, including copper shell ontology, the copper shell ontology is cylinder, by several continuous rows
The copper shell unit composition of row, the copper shell unit top have Piece Claw, and copper shell unit center offers centre bore, the copper shell list
First inside is additionally provided with convex ribs item.The copper shell is provided with centre bore and convex ribs item, injects phenolic moulding powder in process, plays
Copper shell is supported, the effect of copper shell film flying is prevented, improves product qualification rate, reduce production cost, on the other hand, is molded step
Formula structure eliminates the turnery processing of outer circle step compared to the prior art, improves production efficiency.
Further, the convex ribs item bends inwards, and forms a hook portion.Further function as the effect of support phenolic moulding powder.
Further, the Piece Claw outward bending.
Further, the centre bore is rectangular.
Further, the copper shell is attached at commutator face.
The beneficial effects of the utility model are：
A kind of step commutator copper shell described in the utility model, is provided with centre bore and convex ribs item, processed
Phenolic moulding powder is injected in journey, plays the role of supporting copper shell, prevents copper shell film flying, improve product qualification rate, reduce and be produced into
This, on the other hand, molding staircase structural model eliminates the turnery processing of outer circle step compared to the prior art, improves production effect
Rate.
Description of the drawings
Fig. 1 is a kind of structure diagram of step commutator copper shell provided by the utility model.
Fig. 2 is a kind of sectional view of step commutator copper shell provided by the utility model.
Wherein：1 is copper shell ontology, and 2 be copper shell unit, and 3 be Piece Claw, hole centered on 4, and 5 be convex ribs item.
Specific embodiment
Referring to Fig. 1, Fig. 2, it is a kind of structure diagram of step commutator copper shell described in the utility model, wraps
It includes：
A kind of step commutator copper shell, including copper shell ontology 1, the copper shell ontology 1 is cylinder, by several continuous
The copper shell unit 2 of arrangement forms, and 2 top of copper shell unit has Piece Claw 3, and 2 center of copper shell unit offers centre bore 4, institute
It states 2 inside of copper shell unit and is additionally provided with convex ribs item 5.
Further, the convex ribs item 5 bends inwards, and forms a hook portion.
Further, 3 outward bending of Piece Claw.
Further, the centre bore 4 is rectangular.
Further, the copper shell is attached at commutator face.
A kind of step commutator copper shell described in the utility model, is provided with centre bore and convex ribs item, processed
Phenolic moulding powder is injected in journey, plays the role of supporting copper shell, prevents copper shell film flying, improve product qualification rate, reduce and be produced into
This, on the other hand, molding staircase structural model eliminates the turnery processing of outer circle step compared to the prior art, improves production effect
Rate.
It should be noted that above example is merely intended for describing the technical solutions of the present application, but not for limiting the present application.Although ginseng
The utility model is described in detail according to preferred embodiment, it will be understood by those of ordinary skill in the art that, it can be to reality
It is modified or replaced equivalently with novel technical solution, it, should all without departing from the range of technical solutions of the utility model
Cover in the right of the utility model.
