Amount.
Utility model content
The purpose of this utility model is that providing a kind of rotor axis of electric enters shaft device, and it has simple in construction and processing matter
The characteristics of measuring reliable and stable, asking for the easy stress bending of armature spindle that shaft device is present is entered to solve rotor axis of electric in the prior art
Topic.
For up to this purpose, the utility model uses following technical scheme：
A kind of rotor axis of electric enters shaft device, and it includes support base, armature spindle, rotor, pressure head and closing in sleeve, its
In, it is threaded section along its axial direction on the armature spindle and processes fluted along its circumferencial direction, the rotor is arranged at institute
State in support base, the center of the support base offers the centre bore for housing armature spindle, the pressure head is arranged at
The surface of the support base, the pressure head connects drive device, and the armature spindle is inserted in the rotor, the set that closes up
Jacket casing is on the armature spindle stretched out outside the rotor, and the closing in sleeve includes cylinder and is arranged at the sword of described cylinder one end
Mouthful, the diameter of the cutting edge is more than the aperture of the rotor inner hole.
Especially, the groove is opened in the outside of the thread segment.
Especially, it is 45 ° of inclined-planes on the inside of the cutting edge, outside is 20 ° of inclined-planes.
Especially, the locating convex block for being positioned to rotor is provided with the support base.
Especially, the drive device is using any of oil cylinder or cylinder.
The beneficial effects of the utility model are that the rotor axis of electric enters shaft device and covered by closing up compared with prior art
Material at rotor inner hole opening is inwardly squeezed into the fixing assembling that armature spindle is realized in screw thread and groove, whole assembling process by cylinder
Armature spindle is not stressed directly, it is ensured that size.It is not only simple in structure, is easy to operation；And ensure that the assembling quality of armature spindle,
Improve the total quality of motor.

Embodiment
Further illustrate the technical solution of the utility model below in conjunction with the accompanying drawings and by embodiment.
Refer to shown in Fig. 1 to Fig. 3, in the present embodiment, a kind of rotor axis of electric, which enters shaft device, includes support base 1, turns
On sub- axle 2, rotor 3, pressure head 4 and closing in sleeve 5, the armature spindle 2 section 6 is threaded along its axial direction and along its circumferencial direction
Process at fluted 7, the both ends open for opening up position respective rotor endoporus of the groove 7 and set, and the groove 7 is located at institute
State the outside of thread segment 6.
The rotor 3 is arranged in the support base 1, and the center of the support base 1 is offered to be turned for accommodating
The centre bore 8 of sub- axle 2, the pressure head 4 is arranged at the surface of the support base 1, and the pressure head 4 connects drive cylinder, institute
State armature spindle 2 to insert in the rotor 3, the closing in sleeve 5, which is placed on, to be stretched out on the armature spindle 2 outside the rotor 3, and the receipts
Port sleeve 5 includes cylinder 50 and is arranged at the cutting edge 51 of described one end of cylinder 50, and the diameter of the cutting edge 51 is more than the rotor 3
The aperture of endoporus, angle A=45 ° of the medial slope of cutting edge 51, angle B=20 ° on outside inclined-plane.
For the ease of the placement of rotor 3, the convex for being positioned to rotor is provided with the support base 1
Block.
During work, first rotor 3 is positioned in support base 1, and armature spindle 2 is inserted in the rotor inner hole, is being turned
Closing in sleeve 5 is arranged outside sub- axle 2, starts forcing press, pressure head 4 is pressed downward closing in sleeve 5, and closing in sleeve 5 will be turned by cutting edge 51
Material at sub- bore openings is inwardly extruded, and most progress radial rotation is spacing in the screw thread of part material press-in thread segment 6 at last, together
