Abstract
The utility model relates to an assembly tooling of a rotor assembly which is provided with a planar commutator and a back end cover, which pertains to the technical field of a motor production tooling. The utility model comprises a lower positioning base and an upper cover board, the lower positioning base is a vertical circular hollow structure, the middle part of the hollow structure of the lower positioning base is provided with a partition board which is horizontally arranged, an opening is arranged on the side wall of the lower positioning base, the width of the opening is smaller than or equivalent to the inner diameter of the hollow structure, a lower gap which is positioned at the middle of the opening of the side wall of the lower positioning base is arranged on the partition board, the lower gap takes the diameter of the partition board as a central line and extends from the circumference to the circle center of the partition board, the tail end of the lower gap forms a concentric arc with the partition board, the upper cover board is covered at the upper end of the lower positioning base, and an upper gap which is corresponding to the lower gap which is arranged on the partition board is arranged on the upper cover board. The utility model can facilitate the assembly of the rotor assembly which is provided with the planar commutator and the back end cover which is provided with a plurality of carbon brushes, thereby solving the problems of inconvenient assembly of the end cover with a plurality of carbon brushes and the planar commutator, etc. in the prior art.
Description
Technical field
The utility model relates to a kind of rotor assembly and rear end cap assembly tooling with flat commutator, belongs to the technical field of motor production frock.
Technical background
In the prior art, the structure of the flat commutator that the commutator of part motor adopts, adopt the parallel axes of the motor of this kind structure rectifying and carbon brush that flat commutator matches its direction of motion and brush holder under the effect of spring, before rotor assembly and the rear end cap assembling, if do not apply active force to overcome acting force of the spring to carbon brush, then carbon brush can be ejected in brush holder by spring, when carbon brush less, when generally being two, can carbon brush being pushed down with the finger cooperation usually and can carry out the assembling of rear end cap and rotor assembly; But if the carbon brush on the brush holder during more than two, is pressed the pressure carbon brush with finger and is just become infeasible.
Summary of the invention
The utility model purpose is to provide a kind of and is convenient to the rotor assembly of flat commutator and the frock of the assembling of the rear end cap that has a plurality of carbon brush, solved exist in the prior art to problems such as assembling inconvenience between the end cap of a plurality of carbon brush and the flat commutator.
Above-mentioned technical purpose of the present utility model mainly solves by the following technical programs: it comprises positioning seat and upper cover plate down, described positioning seat down is the vertical circular hollow structure, the hollow structure middle part of following positioning seat is provided with horizontally disposed dividing plate, the sidewall of following positioning seat is provided with opening, the width of described opening is less than or equal to the internal diameter of hollow structure, dividing plate is provided with the following breach of the opening setting that is centered at down the positioning seat sidewall, described breach down is that center line extends from the center of circle of the past dividing plate of circumference of dividing plate with the diameter of dividing plate, the end of following breach forms the circular arc concentric with dividing plate, upper cover plate lid is located at down the upper end of positioning seat, and described upper cover plate is provided with and the corresponding last breach of following breach on the dividing plate.Wherein, cavity between dividing plate and the upper cover plate can be used for ccontaining rear end cap, during assembling, rear end cap is put in the cavity between upper cover plate and the dividing plate by the following opening of positioning seat sidewall, one by one carbon brush is assembled on the brush holder of rear end cap again, carbon brush of every assembling can turn over certain angle with end cap, the carbon brush that has assembled can be limited in the brush holder by upper cover plate, all assemble until all carbon brush, then will be inserted in the last breach of upper cover plate with the rotor assembly of flat commutator, the rotor assembly axle head can be cooperated with end cap, again rotor assembly and rear end cap are pulled out from the last breach of upper cover plate and the following breach of dividing plate respectively in the lump, again rotor assembly and rear end cap are assembled with the fastening assembling that can finish rotor assembly and rear end cap of securing member, need not to worry that carbon brush is ejected by spring in the whole process, assemble very convenient.Wherein, last breach on the upper cover plate and the following breach on the dividing plate can make the armature spindle of rotor assembly level shift out, opening on the following positioning seat sidewall then can be realized entering and shifting out of rear end cap, thus can realize rotor assembly and rear end cap in the lump level shift out.
As preferably, the inboard open annular step that is provided with sinking in described positioning seat down upper end, the profile of described upper cover plate and open annular step match.Wherein, the inboard open annular step in following positioning seat upper end cooperates with upper cover plate, upper cover plate can be located, and prevents moving horizontally of upper cover plate.
As preferably, the opening dual-side on the described positioning seat sidewall down is parallel with the diameter of dividing plate, plays the effect of guiding to the turnover of rear end cap, thereby is convenient to the turnover of rear end cap.
Therefore, the utlity model has the rotor assembly of being convenient to flat commutator and the characteristics such as assembling that have the rear end cap of a plurality of carbon brush.
