Specific embodiment
In the following with reference to the drawings and specific embodiments, the present invention is furture elucidated, and the present embodiment is with technical solution of the present invention
Premised under implemented, it should be understood that these examples are only for illustrating the present invention and are not intended to limit the scope of the present invention.
As shown in Figures 1 to 4, the embodiment of the invention provides a kind of traction electric machine assembling auxiliary mould easy to use,
The tooling includes a fixed plate 2, and the fixed plate is preferably circular, and size is preferably consistent with the bearing cap of traction electric machine 1, in fixation
The middle part of plate 2 is equipped with through-hole 21, and the internal diameter of through-hole 21 is greater than the outer diameter of traction electric machine shaft, for when assembling shaft front end from logical
It is pierced by hole 21.Multiple otic placodes 3 are uniformly fixed in 2 surrounding of fixed plate, the threaded hole 102 of the disassembly on general bearing cap 1 is 3
A, therefore, the otic placode 3 of this tooling is preferably 3, and each otic placode 3 is equipped with a fixation hole 31.Fixation hole 31 is passed through by bolt
It is screwed into the threaded hole 102 on bearing cap 1, this tooling can be fixed on bearing cap 1 afterwards.2 right-hand end of fixed plate is vertically solid
Surely there are multiple connecting columns 4, which can be to be welded and fixed or be screwed.The right end of multiple connecting columns 4, i.e., its not with
One end that fixed plate 2 connects is equipped with limiting component, slidably connects at least one slide plate 5, slide plate in the outside of multiple connecting columns 4
5 middle parts are equipped with a bearing 6, and the outer ring of bearing 6 and slide plate 5 are fixed, and a guide rod 7 is fixed in the inner ring of bearing 6, guide rod 7
Left end is equipped with external thread structure, the threaded hole of the external thread structure and traction electric machine rotor front end close to one end of fixed plate 2
It matches.In this way, guide rod 7 can move left and right on connecting column 4 together with slide plate 5, when slide plate 5 slides into left position,
Guide rod 7 can put in the inside of traction electric machine, and guide rod 7 can be screwed into the threaded hole of shaft outer end by rotating guide-bar 7.Then
Control overhead traveling crane makes rotor continue to move into stator, and under the booster action of this tooling, when shaft is mobile, swing substantially reduces,
And then mitigates and bearing is damaged.
The slide plate 5 of the embodiment of the present invention can be one, and when using a slide plate 5, the stability of guide rod 7 is lower, can be with
Be equipped with limit sleeve 8 in at least side of slide plate 5, limit sleeve 8 be preferably arranged far to the side of fixed plate 2, limit sleeve 8 with lead
Bar 7 is arranged concentrically, and guide rod 7 is slidably connected in limit sleeve 8, and limit sleeve 8 can mitigate guide rod 7 and exist with the inner ring of bearing 6
Horizontal swing, and the rotation of guide rod 7 is not influenced.Slide plate 5 may be two, and two slide plates 5 are arranged at intervals on guide rod 7, can also
To mitigate the horizontal swing of guide rod 7, stability is improved.
The limiting component of the embodiment of the present invention is the retention bead 9 for being separately positioned on each 4 end of connecting column.Retention bead
9 can be integrally formed or be welded and fixed with connecting column 4, be also possible to the connection that is screwed.As a preferred embodiment, limiting component
For a limit plate 10, limit plate 10 is ring-shaped, and middle part is equipped with the hole 11 passed through for guide rod 7, and limit plate 10 is fixed on multiple companies
The end of column 4 is connect, limit plate 10 can not only limit slide plate 4, can also improve the stabilization between multiple connecting columns 4
Property, preventing a certain connecting column 4, deformation occurs.
The abnormal sound generated is hit in order to mitigate slide plate 5 and fixed plate 2, is equipped with cushion 12 in the side of slide plate 5.In order to just
In use, rubber sleeve 13 is equipped with far from one end of fixed plate 2 in guide rod 7.For the purposes of being easy to use, connecting column 4 is preferably 3
A, 3 connecting columns 4 are uniformly interspersed with otic placode 3.In this way, each otic placode 3 is just arranged in two 4 interpositions of connecting column
It sets, when fixed plate 2 to be fixed on bearing cap 1, connecting column 4 will not interfere to operate.
In conclusion the present invention can be fixed on the bearing cap of traction electric machine front end, when rotor and stator cooperation assemble,
Before the outer ring position that armature spindle front end reaches roller bearing, convenient for guide rod to be screwed into the threaded hole of shaft outer end, rotor exists
In stator when axial movement, slide plate can slide under the action of guide rod on connecting column, effectively mitigation rotor swing, avoid making
At end bearing before motor is hit partially and scratch the phenomenon that, avoid unnecessary loss.
The above is only a preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, various improvements and modifications may be made without departing from the principle of the present invention, these improvements and modifications are also answered
It is considered as protection scope of the present invention.
