Description
Technical field
The utility model is related to the part on a kind of motor, and in particular to a kind of rotor axis of electric.
Background technology
The small rotating speed of motor general size of small-sized electric tool is high, and what is had also has poor lubrication.Current
, there is play phenomenon in a kind of rotor axis of electric, locating slot is set by using the center of rotor shaft end, the locating slot
The tapered shape of inwall that is open is outwardly open, then places steel ball in the locating slot, the inner bottom part of steel ball and electric machine casing to contacting,
Rotor axis of electric rotate can be in contact by the spherical of steel ball with locating slot inwall it is longitudinal spacing to realize, so as to prevent from altering
The generation of dynamic phenomenon.But need longitudinally to prevent armature spindle in assembling, and locating slot is upward, is then placed in steel ball, most
Motor housing in rear enclosure, in the process, the action of workman are very careful, and careless slightly steel ball can drop, such assembling
Mode extreme influence motor efficiency of assembling, causes the decline of productivity ratio.
The content of the invention
To solve the above problems, the purpose of this utility model prevents the motor that steel ball drops from turning when being to provide a kind of assembling
Sub- axle, improves motor efficiency of assembling.
To achieve the above object, the utility model provides following technical scheme：A kind of rotor axis of electric, including axis body and
Steel ball, the end face of the axis body is provided with the positioning that chamfering at rotational positioning hole, the opening in the rotational positioning hole is in cone
Groove, described steel ball is fixed on by magnet adsorption in described locating slot.
Described magnet is strip, and described rotational positioning bottom hole portion is provided with the pilot hole matched with the magnet,
Described magnet is movable to be fastened in described pilot hole, and described magnet one end is extended in the locating slot, described
Steel ball is placed in described locating slot and is in contact with described magnet end.
Described magnet is placed on the end face of axis body at the opening of the locating slot, and described magnet is annulus
Shape, the circular endoporus is corresponding with the opening of described locating slot, and the hole wall of described magnet endoporus is circular arc, described
When steel ball is placed in described locating slot, the sphere of the steel ball is adsorbed in described magnet endoporus.
Described magnet is arranged on the bottom of the locating slot, and it is fixed that described steel ball is fixed on by the magnetic absorption of magnet
In the groove of position.
By using having the beneficial effect that above-mentioned technical proposal is reached：Steel ball by magnet adsorption in locating slot after can
Steel ball is set to be difficult to drop out of locating slot, such workman is in assembling, and armature spindle can arbitrarily place installation, effectively increase motor
The speed of assembling, so as to reach the technique effect for preventing steel ball from dropping during assembling, improves motor efficiency of assembling.
The utility model is further described with reference to the accompanying drawings and detailed description.
Brief description of the drawings
Fig. 1 is the stereogram of the utility model embodiment；
Fig. 2 is the structure chart of embodiment one；
Fig. 3 is the structure chart of embodiment two；
Fig. 4 is the structure chart of embodiment three.
Embodiment
The utility model is specifically described below by embodiment, is served only for carrying out further the utility model
Explanation, it is impossible to be interpreted as the restriction to the utility model protection domain.
As shown in figure 1, this rotor axis of electric, including axis body 1 and steel ball 2, the end face of axis body 1 is provided with rotational positioning hole
11, chamfering is in the locating slot 12 of cone at the opening in rotational positioning hole 11, and steel ball 2 is absorbed and fixed at locating slot by magnet 3
In 12.
As shown in Fig. 2 magnet 3 is strip, the bottom of rotational positioning hole 11 is provided with the pilot hole 13 matched with magnet 3,
Magnet 3 is movable to be fastened in pilot hole 13, and the one end of magnet 3 is extended in locating slot 12, steel ball 2 be placed in locating slot 12 with
The end of magnet 3 is in contact.So steel ball 2 is absorbed and fixed at the end of magnet 3, can prevent steel ball 2 from dropping during assembling, the meeting of steel ball 2
The inner bottom part of motor housing is connected to, while steel ball 2 understands in activity to locating slot 12 and drive magnet 3 is lived along pilot hole 13
It is dynamic, so as to complete the assembling of motor.
As shown in figure 3, magnet 3 is placed on the end face of axis body 1 at the opening of locating slot 12, magnet 3 is annular shape,
The circular endoporus is corresponding with the opening of locating slot 12, and the hole wall of the endoporus of magnet 3 is circular arc 31, and steel ball 2 is placed on fixed
When in the groove 12 of position, the sphere of steel ball 2 is adsorbed in the endoporus of magnet 3.It can prevent steel ball 2 from dropping when so assembling, and directly will be logical
Cross magnet 3 and adsorb steel ball 2 and motor housing assembling, it is very convenient, improve efficiency of assembling.
As shown in figure 4, magnet 3 is arranged on the bottom of locating slot 12, it is fixed that steel ball 2 is fixed on by the magnetic absorption of magnet 3
In the groove 12 of position.It can prevent steel ball 2 from dropping when so assembling, install convenient improves efficiency of assembling.
In embodiment, steel ball 2 can make steel ball 2 be difficult to fall out of locating slot 12 after being adsorbed by magnet 3 in locating slot 12
Fall, such workman is in assembling, and armature spindle can arbitrarily place installation, the speed of motor assembling is effectively increased, so as to reach
The technique effect for preventing steel ball 2 from dropping during assembling, improves motor efficiency of assembling.
