Abstract
The invention discloses a kind of manufacturing methods of carbon brush motor rotor, comprising the following steps: rushes shape；Tinertoy；Coating；It is packed into commutator；Coiling；Electric resistance welding: electric resistance welding is carried out to commutator foot；Punching；Scolding tin.The working efficiency and yields of scolding tin process can be improved in the manufacturing method of carbon brush motor rotor provided by the invention.
Description
Technical field
The present invention relates to the manufacturing methods of motor rotor, specifically, being related to a kind of manufacturing method of carbon brush motor rotor.
Background technique
Existing motor rotor during fabrication, due to commutator foot be copper material, surface meeting under natural environmental condition
Oxidation forms copper oxide, and in electric resistance welding process, commutator foot generates high temperature and the copper oxide on surface is thickeied, because of copper oxide
It is not affine with scolding tin, cause to be unfavorable for commutator foot in scolding tin process and varistor forms good bump, scolding tin work
Make low efficiency, fraction defective is high.
Summary of the invention
The purpose of the present invention is to provide a kind of manufacturing methods of carbon brush motor rotor, improve the work effect of scolding tin process
Rate and yields.
Technical solution used by the manufacturing method of carbon brush motor rotor disclosed by the invention is:
A kind of manufacturing method of carbon brush motor rotor, comprising the following steps:
It rushes shape: shape is rushed to selenium steel disc or silicon steel sheet；Tinertoy；Coating；It is packed into commutator；Coiling；Electric resistance welding: to commutator foot
Carry out electric resistance welding；Punching: it is punched on commutator foot；Scolding tin: commutator foot is subjected to scolding tin with varistor and is connected.
The beneficial effect of the manufacturing method of carbon brush motor rotor disclosed by the invention is: before scolding tin, by commutator foot
Upper punching, destroys the oxide layer on commutator foot, and bare metal copper since copper and scolding tin have preferable affinity, and commutates
Hole on device foot facilitates the infiltration of scolding tin, conducive to the fusion of commutator foot and scolding tin, improve scolding tin process working efficiency and
Yields, while the pull-out force between scolding tin and commutator foot can be improved.
Detailed description of the invention
Fig. 1 is the flow chart of the manufacturing method of carbon brush motor rotor of the present invention.
Specific embodiment
The present invention is further elaborated and is illustrated with Figure of description combined with specific embodiments below:
A kind of manufacturing method of carbon brush motor rotor, comprising the following steps:
S1 rushes shape: rushing shape to selenium steel disc or silicon steel sheet；
S2 tinertoy: selenium steel disc or silicon steel sheet after rushing shape are superimposed together to form rotor by motor shaft；
S3 coating: insulated paint is coated to internal rotor coiling position；
S4 is packed into commutator: commutator is loaded on motor shaft；
S5 coiling；
S6 electric resistance welding: electric resistance welding is carried out to commutator foot；
S7 punching: it is punched on commutator foot；
S8 scolding tin: commutator foot is subjected to scolding tin with varistor and is connected.
By punching on commutator foot, the oxide layer on commutator foot, bare metal copper, since copper and scolding tin have are destroyed
There is preferable affinity, and the hole on commutator foot facilitates the infiltration of scolding tin, conducive to the fusion of commutator foot and scolding tin, improves
The working efficiency and yields of scolding tin process, while the pull-out force between scolding tin and commutator foot can be improved.
Finally it should be noted that the above embodiments are merely illustrative of the technical solutions of the present invention, rather than the present invention is protected
The limitation of range is protected, although explaining in detail referring to preferred embodiment to the present invention, those skilled in the art are answered
Work as understanding, it can be with modification or equivalent replacement of the technical solution of the present invention are made, without departing from the reality of technical solution of the present invention
Matter and range.
