Description
Technical field
The utility model belongs to a kind of miniature linear motor, more particularly to convert rotational motion is linear motion by one kind
The miniature linear stepping motor of function.
Background technology
Linear stepping motor common at present has two kinds：Magneto and hybrid.The drving sprial pair position of general design
It is in：1st, outside rotor assembly, i.e., outside electric rotating machine.Drving sprial is secondary and guider is all distributed in outside electric rotating machine
On axle, cause whole axial direction or circumferential lengths big.Or, 2, inside rotor assembly.Because internal rotor needs to accommodate underdrive
Screw thread pair, this can allow designer to be accepted or rejected on motor performance and motor volume.
In sum, common miniature straight line electric chance has that appearance and size is larger.
Utility model content
The utility model provides a kind of new micro linear motor, and the shortcoming its object is to solve prior art is carried
For the simplified structure that a kind of convert rotational motion is linear motion function, realize that motion and the straight line of power are exported, while reaching
Axial length is short, the characteristics of circumferential size is small.
The utility model solves the technical scheme that its technical problem used：
A kind of new micro linear motor, it is characterised in that：With a miniature electric rotating machine assembly, miniature electric rotating
Rotor assembly is rotatably arranged with machine assembly, rotor assembly has hollow axle center；Rotor assembly is fixed in one end of screw rod
Quill shaft it is intracardiac and be fixedly connected with rotor assembly, the other end of screw rod is the end of thread；With the axis of guide and fairlead structure
Into guider assembly, the axis of guide and fairlead are cooperated with polygon outer wall or are coordinated with keyway arrangements, and make guiding
Axle and fairlead can not relatively rotate and can axial relative linear motion, fairlead is connected with miniature electric rotating machine assembly, spiral shell
The end of thread of bar forms screw pair and coordinates with the disposed thread of the axis of guide.
Miniature electric rotating machine assembly can be dc rotating machine or rotation stepping motor.
Fairlead outer wall tool is screw thread or optical axis.
One end of fairlead connects firmly with miniature electric rotating machine assembly, and the end has endoporus outer with electric rotating machine assembly
Seam coordinates.
It is of the present utility model to be beneficial in that：
1st, the quill shaft for being fixed on rotor assembly by one end of screw rod is intracardiac, is fixedly connected with rotor assembly, it is to avoid
Increase the hollow volume in axle center of rotor assembly, it is ensured that the performance of miniature electric rotating machine, such as torque.
2nd, the disposed thread and screw flight of the axis of guide are spiral secondary combination, and profile and the fairlead of the axis of guide coordinate, limit
Circumferential movement processed.When screw rod follows the hollow axle center rotary motion of rotor assembly, due to fairlead limitation radially and circumferentially
Motion, so that the axis of guide does axial Precision Linear Moving.Designed by this, simplify the guide frame of screw pair, contracted
Small axial direction and circumferential volume.
3rd, outside above-mentioned fairlead can be thread profile, it is right that user can be easily done directly by aforementioned threads profile
The axial restraint of motor, can apply to the occasion not high to radial direction status requirement；And the application higher to status requirement, it is optional
Select the fairlead profile of optical axis.In brief, the fixed installation unit of conventional motors, not only needs the position of reserved fairlead,
It is also required to fix the installation site of motor simultaneously；And designed by this, the area of the fixed cell of user is more succinct, that is, lead
Outer shape to set can more be adapted to the less application in space.
4th, the male half coupling that the other end of fairlead has endoporus and miniature electric rotating machine assembly coordinates, to ensure that fairlead is
To the concentricity of whole guider and miniature electric rotating machine assembly.The concentricity is the radial beat amount for controlling the axis of guide, and
Avoid the key point of elongate threaded screw unstability.
5 thus the utility model on the basis of miniature electric rotating machine performance is retained, simplify the structure of guider,
Axial direction and circumferential volume are reduced, is adapted to the less application scenario in space, and can guarantee that guider is total with miniature electric rotating machine
Into concentricity requirement.
Brief description of the drawings
The utility model is further illustrated with reference to the accompanying drawings and examples.
Fig. 1 is planar explosive sectional view of the present utility model；
Fig. 2 is exploded perspective figure of the present utility model.
Fig. 3 is outside drawing of the present utility model.
Specific embodiment
As shown in Figure 1, Figure 2, Figure 3 shows, the utility model has a miniature electric rotating machine assembly 1, miniature electric rotating machine assembly 1
A rotor assembly 13 for the achievable rotary motion set up with bearing is inside arranged with, rotor assembly 13 has hollow axle center 14,
One end 11 of screw rod 2 is fixed in the hollow axle center 14 of rotor assembly 13, is fixedly connected with rotor assembly 13.Palpus during this
By controlling the hollow axle center 14 of rotor assembly 13 and processing and the build-up tolerance of screw rod 2, to ensure rotor assembly 13 and screw rod 2
Axiality.
Miniature electric rotating machine assembly 1 is electric rotating machine, can be dc rotating machine, rotating stepper motor, but is not limited to
Above-mentioned motor, what the present embodiment was selected is the magneto rotation stepping motor of external diameter 15mm.
The other end of screw rod 2 is that the end of thread 12 coordinates with a guider assembly 3, and guider assembly 3 has the axis of guide 5
With the two parts of fairlead 4.The internal thread 20 of fairlead 4 is screwed togather with the external screw thread 21 of miniature electric rotating machine assembly 1 and consolidates the two
Connection.There is endoporus 16 to coordinate with the male half coupling 15 of miniature electric rotating machine assembly 1 for one end of fairlead 4, to ensure fairlead 4 and lead
To the axiality of axle 5 and miniature electric rotating machine assembly 1.
The disposed thread 19 of the axis of guide 5, the disposed thread 19 can injection moulding or machining completion.The profile of the axis of guide 5
Including external splines 8, the internal spline targeting port 18 with fairlead 4 coordinates.The profile of the axis of guide 5 can also include that milling is flat or polygon
Part, but above-mentioned profile is not limited to, effect is coordinated with the corresponding part of fairlead 4, can prevent circumferentially rotating for the axis of guide 5,
Realize the axial tandem motion of the axis of guide 5；
So far, the end of thread 12 of screw rod 2 forms screw pair and coordinates with 5 disposed thread of the axis of guide 19, and the spline of the axis of guide 5
Profile coordinates with fairlead 4, circumferentially rotates and is prevented from, and realizes axially directed.So when screw rod 2 is with miniature electric rotating machine assembly
1 when rotating in either direction, and the axis of guide 5 can realize unidirectional axial linear movement.
The outside of fairlead 4 has the profile of screw thread 17 or optical axis (not shown).User can be by thread profile easily
The axial restraint to motor is done directly, the occasion not high to radial direction status requirement is can apply to；And it is higher to status requirement
Application, may be selected optical axis fairlead profile.In brief, the fixed installation unit of conventional motors, not only needs reserved leading
To the position of set, while being also required to fix the installation site of motor；And designed by this, the area of the fixed cell of user is more
For succinct, i.e., the outer shape of fairlead can more be adapted to the less application in space.
