Description

Double-shaft rotary motion stepping motor

Technical Field

The utility model relates to a motor field specifically is a biax rotary motion step motor.

Background

A stepper motor is an electric motor that converts electrical pulse signals into corresponding angular or linear displacements. The rotor rotates an angle or one step before inputting a pulse signal, the output angular displacement or linear displacement is proportional to the input pulse number, and the rotating speed is proportional to the pulse frequency. However, the existing stepping motor cannot realize simultaneous reverse rotation of the double shafts, so that the required use effect is difficult to achieve.

SUMMERY OF THE UTILITY MODEL

In order to solve the problems, the utility model provides a technical scheme that a double-shaft rotary motion stepping motor comprises a motor shell and a front motor, wherein the front motor is internally provided with a large mounting hole penetrating through the front and the rear; the motor also comprises a rear motor, wherein a small mounting hole penetrating through the front part and the rear part is formed in the rear motor; a motor connecting plate is arranged between the front motor and the rear motor.

Preferably, the motor also comprises a front motor hollow rotating shaft, and the front motor hollow rotating shaft is fixed in the large mounting hole.

Preferably, the motor further comprises a rear motor rotating shaft, wherein the rear motor rotating shaft is fixed in the small mounting hole and penetrates through the front motor hollow rotating shaft.

Preferably, the motor connecting plate is fixed with the front motor and the rear motor through connecting screws.

Preferably, the front end of the rear motor rotating shaft is sleeved with a bearing, and a clamp spring is fixed to the front end of the bearing.

Compared with the prior art, the beneficial effects of the utility model are as follows:

the hollow shaft and the solid shaft are supported by the bearing to ensure that the hollow shaft and the solid shaft are concentric; and the front motor and the rear motor respectively drive the hollow shaft and the solid shaft, so that the controllability and the stability of the rotation of the two shafts are improved.

Drawings

FIG. 1 is an exploded view of the present invention;

in the figure: the motor comprises a motor shell 1, a front motor 2, a large mounting hole 3, a rear motor 4, a small mounting hole 5, a motor connecting plate 6, a hollow rotating shaft of the front motor 7, a rotating shaft of the rear motor 8, a connecting screw 9, a bearing 10 and a clamp spring 11.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1, a double-shaft rotary motion stepping motor comprises a motor housing 1, including a front motor 2, wherein a front and a rear large mounting holes 3 are formed in the front motor 2; the motor also comprises a rear motor 4, wherein a small mounting hole 5 penetrating through the front and the rear of the rear motor 4 is formed in the rear motor 4; a motor connecting plate 6 is arranged between the front motor 2 and the rear motor 4. The front motor and the rear motor are arranged to realize segmented rotation and realize independent control on different shafts.

The motor is characterized by further comprising a front motor hollow rotating shaft 7, wherein the front motor hollow rotating shaft 7 is fixed in the large mounting hole 3. The motor is characterized by further comprising a rear motor rotating shaft 8, wherein the rear motor rotating shaft 8 is fixed in the small mounting hole 5 and penetrates through the front motor hollow rotating shaft 7. The motor connecting plate 6 is fixed with the front motor 2 and the rear motor 4 through a connecting screw 9. The front end of the rear motor rotating shaft 8 is sleeved with a bearing 10, and a clamp spring 11 is fixed to the front end of the bearing 10. A stepping motor realizes the same-direction rotation motion of two shafts and the reverse rotation motion of the two shafts simultaneously in the same shaft outlet direction. The front motor drives the front motor hollow rotating shaft 7 of the outer ring to rotate, and the front motor can rotate forwards and backwards; the rear motor drives a rear motor rotating shaft 8 in the hollow shaft to rotate, and the rear motor can rotate forward or backward. The two can work together or be controlled separately. The hollow shaft and the solid shaft are supported by a bearing fixed through a clamp spring, and the concentricity of the hollow shaft and the solid shaft is ensured.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
