Description
Technical field
The utility model is related to the parts on a kind of motor, and in particular to a kind of band shift fork armature spindle.
Background technology
The small rotating speed of motor general size of small-sized electric tool is high, and having on motor on armature spindle, some armature spindles to set
There is shift fork to be used for the connection with rotatable parts,（Such as wiper etc）, there is play phenomenon, one in such a rotor axis of electric
As by using the center of rotor shaft end, locating slot is set, the tapered shape of opening inwall of the locating slot is outwardly open,
Then steel ball is placed in the locating slot, the inner bottom part of steel ball and electric machine casing is to contacting, and rotor axis of electric, which is rotated, can pass through steel ball
Spherical be in contact with locating slot inwall it is longitudinal spacing to realize, so as to prevent the generation of play phenomenon.But in assembling
When need longitudinally to prevent armature spindle, and locating slot is upward, is then placed in steel ball, finally puts motor housing, in this process
In, the action of workman is very careful, and careless slightly steel ball can drop, such assembling mode extreme influence motor assembling effect
Rate, causes the decline of productivity ratio.
The content of the invention
To solve the above problems, the purpose of this utility model is that providing one kind makes steel ball fix reliable band shift fork rotor
Axle, improves efficiency of assembling.
To achieve the above object, the utility model provides following technical scheme：A kind of band shift fork armature spindle, including axis body
And steel ball, one end of axis body is provided with shift fork, and the other end of the axis body is provided with chamfering at positioning hole, the opening of the positioning hole
In the locating slot of cone, described axis body end sleeve is provided with the cutting ferrule corresponding with described locating slot, in described positioning
Provided with mobilizable steel ball seat in hole, described steel ball seat end and described cutting ferrule formation supply the spacing of steel ball activity
Chamber, described cutting ferrule is provided with circular hole, and described steel ball side is passed from the circular hole, in steel ball seat and the positioning hole
Compression spring is additionally provided between bottom.
Described steel ball seat is cylindrical, and the cylindric opening is opened wide laterally in coniform, the opening inwall and
Described cutting ferrule inwall forms described limit chamber, and described steel ball is placed in the limit chamber.
The compression spring is set in described steel ball seat above and is connected on described steel ball seat opening outer wall.
Its taper is identical with the conical cell wall of the locating slot for the coniform opening outer wall of the steel ball seat.
By using having the beneficial effect that above-mentioned technical proposal is reached：Steel ball seat end and cutting ferrule formation are for steel ball activity
Limit chamber, cutting ferrule be provided with circular hole, steel ball seat in the presence of compression spring drive steel ball side passed from the circular hole, from
And the fixation of steel ball is ensure that, such workman is in assembling, and armature spindle can be placed arbitrarily to be assembled with motor housing, so as to ensure that
Armature spindle will not free play, effectively increase the speed of motor assembling, so as to reach that steel ball fixes reliable technique effect,
Improve 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 structure chart of the utility model embodiment；
Fig. 2 is the structural representation between positioning hole and steel ball.
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 and Figure 2, the utility model discloses a kind of band armature spindle of shift fork 11, including axis body 1 and steel ball 2, axle
One end of body 1 is provided with shift fork 11, and it is in circular cone that the other end of axis body 1, which is provided with chamfering at positioning hole 12, the opening 41 of positioning hole 12,
The locating slot 13 of shape, the end sleeve of axis body 1 is provided with the cutting ferrule 3 corresponding with locating slot 13, provided with mobilizable in positioning hole 12
Steel ball seat 4, steel ball 4 ends of seat and the formation of cutting ferrule 3 are for the movable limit chamber 5 of steel ball 2, and cutting ferrule 3 is provided with circular hole 31, steel ball 2 one
Side is passed from the circular hole 31, and compression spring 6 is additionally provided between steel ball seat 4 and the bottom of positioning hole 12.
Steel ball seat 4 is cylindrical, and the cylindric opening 41 is opened wide laterally in coniform, 41 inwalls of opening and cutting ferrule 3
Inwall formation limit chamber 5, steel ball 2 is placed in the limit chamber 5.Such limit chamber 5 can effectively limit the activity of steel ball 2, enter one
Step improves the reliability that steel ball 2 is fixed.
Compression spring 6 is set on steel ball seat 4 and is connected to steel ball seat 4 and is open on 41 outer walls.Compression spring 6 can so be made
Work it is relatively reliable, improve steel ball seat 4 with cutting ferrule 3 coordinate stability, make limit chamber 5 to the spacing relatively reliable of steel ball 2.
Its taper is identical with the conical cell wall of locating slot 13 for the outer wall of coniform opening 41 of steel ball seat 4.Such design
When can make 4 compression retraction of steel ball seat, the contact surface of its coniform opening 41 outer walls and the conical cell wall of locating slot 13 is bigger, protects
The stability that steel ball seat 4 shrinks has been demonstrate,proved, the reliability that steel ball 2 is fixed further is improved.
In embodiment, steel ball 4 ends of seat and the formation of cutting ferrule 3 are for the limit chamber 5 of the activity of steel ball 2, and cutting ferrule 3 is provided with circular hole
31, steel ball seat 4 drives the side of steel ball 2 to be passed from the circular hole 31 in the presence of compression spring 6, so as to ensure that steel ball 2
Fixed, such workman is in assembling, and armature spindle can be placed arbitrarily to be assembled with motor housing, so as to ensure that armature spindle will not be free
Play, effectively increases the speed of motor assembling, so as to reach that steel ball 2 fixes reliable technique effect, improves motor assembling
Efficiency.
