Abstract
The present invention relates to a kind of yoke structure of stepping motor, described yoke comprises: the upper guide portion of the portion of blocking of bottom, inclination a °, the gear teeth of central authorities and take turns a plurality of through holes and the protuberance that there is setpoint distance the space of teeth with described, and described yoke structure can carry out lamination with a kind of yoke.
Description
Technical field
The present invention relates to the yoke structure of stepping motor, be specifically related to carry out with a kind of yoke the yoke structure of the stepping motor of lamination.
Background technology
As shown in Figure 1, in yoke 110, yoke 111 and yoke 112, yoke 110 and yoke 111 are with a kind of yoke, and the angle direction that the gear teeth of remaining yoke 112 form is different with yoke 111 with yoke 110.
Each yoke 110, yoke 111 and yoke 112 comprise the bottom the portion of blocking 116, central authorities the gear teeth 115 and and 115 on the gear teeth be separated with the through hole 114 and the protuberance 113 of setpoint distance.
The gear teeth 115 of yoke 110 are towards the below; Yoke 111 combines with the back side of described yoke 110, and its gear teeth 115 are towards the top; The gear teeth 115 of yoke 112 are towards the below.
Therefore, the gear teeth 115 of yoke 111 are relative with the gear teeth 115 of yoke 112, and the gear teeth 115 of the gear teeth of yoke 110 115 and yoke 111 are towards lamination on the contrary.
Because described yoke 110 and yoke 111, different respectively with the angle direction of the gear teeth of yoke 112, so need to make respectively, need extra mould, therefore the manufacturing cost that drops into is bigger.
Summary of the invention
To the objective of the invention is in order addressing the above problem, to provide, thereby can lamination become the yoke structure of the stepping motor of a plurality of yokes with a kind of Mold Making yoke.
As an example according to the yoke structure of stepping motor of the present invention, described yoke comprises: the upper guide portion of the portion of blocking of bottom, inclination a °, the gear teeth of central authorities and take turns a plurality of through holes and the protuberance that there is setpoint distance the space of teeth with described.
Yoke structure according to stepping motor of the present invention, in order to solve the directional problems of the yoke gear teeth when the yoke of lamination stepping motor, the structure of yoke is become guide structure with multi-direction assembling with folk prescription to the guide structure of assembling from existing, thereby change two kinds of yokes of original lamination into lamination a kind of yoke, and when lamination, can not influence the angle of the yoke gear teeth, and only need a kind of yoke, therefore only need a kind of mould, thereby reduced the maintenance management expense of mould, realize the reduction of cost, can guarantee stable quality simultaneously.
In this explanation only is a execution mode according to the yoke structure of stepping motor of the present invention; the invention is not restricted to this execution mode; according to the scope of being protected in claims, the numerous variations execution mode that those skilled in the art may implement under the prerequisite that does not break away from purport of the present invention all belongs to protection scope of the present invention.
Description of drawings
Fig. 1 is the schematic diagram of the yoke structure of existing stepping motor.
Fig. 2 is the schematic diagram according to the yoke structure of stepping motor of the present invention.
Fig. 3 is the assembly drawing according to the yoke structure of stepping motor of the present invention.
Embodiment
Below, with reference to the description of drawings embodiments of the present invention.
As shown in Figures 2 and 3, yoke 10, yoke 11 and yoke 12 are identical yoke, and yoke 10, yoke 11 and yoke 12 comprise respectively: the upper guide portion 18 of the portion of blocking 16 of bottom, inclination a °, the gear teeth 15 of central authorities and and 15 on the described gear teeth be separated with a plurality of through holes 14 and the protuberance 13 of setpoint distance.In the drawings, two through holes 14 and a protuberance 13 become one group, are provided with 2 groups in both sides, form symmetric relation.Because yoke 11 is shown as the back side, so can't see protuberance 13.
The a of upper guide portion 18 ° inclination angle is the step angle of motor.For example, when motor rotated with 7.5 ° of step angles, a ° of inclination angle was 7.5 °, and when motor rotated with 15 ° of step angles, a ° of inclination angle was 15 °.
Yoke 10 and yoke 11 are the positive and negative relation, and yoke 10 and yoke 12 are for the vertical line being the relation of benchmark Rotate 180 °.
With Fig. 2 is benchmark, and yoke 12 is arranged to its gear teeth 15 down, and yoke 11 is arranged to its gear teeth 15 up, and yoke 10 is arranged to its gear teeth 15 down.
Therefore, the gear teeth 15 of yoke 11 are relative with the gear teeth 15 of yoke 12, and the gear teeth 15 of yoke 10 and the gear teeth 15 of yoke 11 are towards on the contrary.
Therefore, can carry out lamination according to the required direction of the yoke gear teeth.
The protuberance 13 of yoke 10 is inserted in the through hole 14 of yoke 11, and the protuberance 13 of yoke 12 is inserted in the through hole of tooth plate shown in Figure 36.
In Fig. 3, Reference numeral 5 is bobbin (bobbin).
As mentioned above, in order to solve the directional problems of the yoke gear teeth when the yoke of lamination stepping motor, yoke structure according to the present invention becomes guide structure with multi-direction assembling with folk prescription to the guide structure of assembling from existing, therefore the two kinds of yokes of lamination with the past change a kind of yoke of lamination into, thereby can not influence the angle of the yoke gear teeth when lamination.
In addition, owing to only need a kind of yoke, thus only need a kind of mould, thus the maintenance management expense of mould reduced, reduced cost, can guarantee stable quality simultaneously.
