Abstract
The utility model discloses a kind of vehicle air regulating valve permanent magnetism stepper motor driving screws, are applied to an electric machine, including a main body bar；And two positioning elements, the positioning element are arranged on the main body bar and the main body bar are assembled in the electric machine, the distance between described positioning element is less than the axial length of the main body bar.It since the main body bar and the electric machine are assembled by the positioning ring, and is the mode of one end and center assembly, so that the beneficial effects of the utility model are that the volume of the motor after assembling effectively is shortened.
Description
Technical field
The utility model relates to machinery equipment field more particularly to a kind of vehicle air regulating valve permanent magnetism stepper motor guide screws
Bar.
Background technique
Today of life is entered into precision instrument, permanent magnetism stepper motor is very universal in the utilization of automotive field, and
Driving screw is the critical component of vehicle air regulating valve permanent magnetism stepper motor.
Stepper motor is to rotate to drive driving screw screw thread rotation by rotor, then by screw-driven, ultimately form screw thread
The linear motion of upper cap nut.
Due to principles above, driving screw needs to keep concentric with motor stator in stepper motor.In the prior art scheme,
To ensure that driving screw and motor stator are concentric, driving screw both ends are mostly processed as arc-shaped.During installation, driving screw both ends are pacified
Loaded on two in motor stator axially concentric circular arc mounting hole.
But the shortcomings that such technical solution, is, increases the volume and manufacturing cost of motor, can not adapt to vehicle air
The requirement of regulating valve permanent magnetism stepper motor micromation.
Utility model content
The utility model is led mainly solving the technical problems that providing a kind of vehicle air regulating valve permanent magnetism stepper motor
Screw rod, so that the driving screw can satisfy the micromation requirement of permanent magnetism stepper motor driving screw.
In order to solve the above-mentioned technical problem, the utility model provides technical solution below:
A kind of vehicle air regulating valve permanent magnetism stepper motor driving screw is applied to an electric machine, comprising:
One main body bar；And
Two positioning elements, the positioning element are arranged on the main body bar and the main body bar are assembled to the motor
In device, the distance between described positioning element is less than the axial length of the main body bar.
Preferably, each positioning element includes a positioning ring, one of them described positioning ring is arranged in the guide screw
The rod end position of the driving screw is arranged in the center of bar, another described positioning ring.
Preferably, the positioning ring is integrally formed ground and is arranged in the main body bar.
By using above technical solution, since the main body bar and the electric machine are filled by the positioning ring
Match, and be the mode of one end and center assembly, so that the beneficial effects of the utility model are the body of the motor after assembling
Product is effectively shortened.
By the understanding to subsequent description and attached drawing, the further purpose of the utility model and advantage will be able to abundant body
It is existing.
The these and other objects of the utility model, feature and advantage, by following detailed descriptions, attached drawing and right are wanted
It acquires to fully demonstrate.
Detailed description of the invention
Fig. 1 is the overall schematic of the vehicle air regulating valve permanent magnetism stepper motor driving screw of the utility model.
Specific embodiment
It is described below for disclosing the utility model so that those skilled in the art can be realized the utility model.It retouches below
Preferred embodiment in stating is only used as illustrating, it may occur to persons skilled in the art that other obvious modifications.It is retouched following
The basic principle of the utility model defined in stating can be applied to other embodiments, deformation scheme, improvement project, etc. Tongfangs
The other technologies scheme of case and the spirit and scope without departing from the utility model.
It will be understood by those skilled in the art that in the exposure of the utility model, term " longitudinal direction ", " transverse direction ", "upper",
The orientation or position of the instructions such as "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outside"
Relationship is to be based on the orientation or positional relationship shown in the drawings, and is merely for convenience of describing the present invention and simplifying the description, and
It is not that the device of indication or suggestion meaning or element must have a particular orientation, be constructed and operated in a specific orientation, therefore
Above-mentioned term should not be understood as limiting the present invention.
It is understood that term " one " is interpreted as " at least one " or " one or more ", i.e., in one embodiment,
The quantity of one element can be one, and in a further embodiment, the quantity of the element can be it is multiple, term " one " is no
It can be interpreted as the limitation to quantity.
As shown in Figure 1, the utility model provides a kind of vehicle air regulating valve permanent magnetism stepper motor driving screw, the vehicle
Carrying air control valve permanent magnetism stepper motor driving screw includes a main body bar 10, and the main body bar 10 is driven by a rotor,
And the main body bar 10 is provided with an external screw thread, and the external screw thread rotation is driven, therefore the main body bar 10 and the electricity
Machine rotor is mutually driven.
There are two positioning element 20, the positioning element 20 includes a positioning ring 21, institute for setting in the main body bar 10
It states positioning ring 21 and is separately positioned on the main body bar 10, and the positioning ring in the electric machine for installing the master
Body rod 10.
In general manufacturing technology, the driving screw and the motor stator axis are mutually driven, and the driving screw
Both ends length be separately connected the motor stator axis, therefore entire length not can be reduced always.And in the present embodiment, the master
The position of the positioning ring 21 on body rod 10 enables to the mounting distance of the driving screw and the motor stator axis to shorten,
Therefore the electric motor can integrally reach the requirement of micromation.
Specifically, the center of the main body bar 10 is arranged in first positioning element 20, that is to say, that described
Positioning ring 21 be arranged in the main body bar 10 center.
The polished rod end position of the main body bar 10 is arranged in second positioning element 20, that is to say, that the positioning ring
21 be arranged in the main body bar 10 polished rod end position.
By the operation of above-mentioned two positioning element 20, the both ends connection type of original driving screw is changed to it
In one in center, another connection type in polished rod end position.Therefore, in assembling process, the electric machine
Overall volume can be reduced, enable the permanent magnetism stepper motor to reach demand miniaturization.Also, the positioning ring
21 surface is smooth, enable be fixedly mounted when precision assembly.
It should be understood by those skilled in the art that foregoing description and the embodiments of the present invention shown in the drawings are only used as
It illustrates and is not intended to limit the utility model.The purpose of this utility model completely and effectively realizes.The function of the utility model
Energy and structural principle show and illustrate in embodiment, under without departing from the principle, the embodiments of the present invention
Can there are any deformation or modification.
