Abstract
The invention proposes a large-scale variable-speed adjustment mechanism with an electric actuator, and the mechanism comprises the electric actuator, a cam, and a driven wheel, wherein the electric actuator, the cam and the driven wheel are connected sequentially. The driven wheel is connected with a push rod through a pin shaft, and the push rod is disposed on a sliding rail. According to the invention, a variable speed movement device and an equal-speed movement electric actuation mechanism are integrated into a body, thereby achieving different moving speeds at some stages of a whole travel, and achieving the variable-speed adjustment, wherein the adjustment speed change is greater than 5-10 times.
Description
Technical field
The invention belongs to topworks's technical field, particularly relate to a kind of can the electric operator of vast scale gearshift adjustment.
Background technology
In order to meet the place of some special process requirements in industry automatic control process, electric operator can be required to realize realizing different reaction velocitys in certain stroke range, and governing speed change is greater than 5 to 10 times.Existing electric operator function realizes gearshift adjustment by converter technique, but cannot realize the adjustment of such vast scale.
Summary of the invention
In view of this, the invention provides a kind of electric operator of vast scale gearshift adjustment, solve the restriction of electric operator vast scale gearshift adjustment.
Technical scheme of the present invention is achieved in that
A vast scale variable regulating mechanism for electric actuator, comprises electric actuator, and the output shaft of described electric actuator connects cam, and described cam connects engaged wheel, and described engaged wheel is by pinned connection push rod, and described push rod is arranged on slideway.
Further, on the supporting plate, described back up pad is fixed in electric actuator through output shaft described installation of slide track.
Further, described slideway is fixing on the supporting plate by flange.
Further, described output shaft is rotated by key band moving cam.
Further, described cam has the curved profile of diameter change, and the ratio of described diameter change is greater than 5 to 10 times.
Relative to prior art, the vast scale variable regulating mechanism of a kind of electric actuator of the present invention has following advantage:
The electric operator of variable motion device and movement at the uniform velocity combines by the present invention, just can realize different movement velocitys in some stage of whole stroke, thus reach the object of gearshift adjustment, and governing speed change is greater than 5 to 10 times.
Accompanying drawing explanation
Accompanying drawing is used to provide a further understanding of the present invention, and schematic description and description of the present invention, for explaining the present invention, does not form the improper restriction to invention.In the accompanying drawings:
Fig. 1 is structural representation of the present invention.
Wherein:
1, electric actuator; 2, output shaft;
3, key; 4, cam;
5, engaged wheel; 6, bearing pin;
7, push rod; 8, slideway;
9, back up pad; 10, flange.
Embodiment
It should be noted that, when not conflicting, the embodiment in the present invention and the feature in embodiment can combine mutually.
Below with reference to the accompanying drawings and describe the present invention in detail in conjunction with the embodiments.
As shown in Figure 1, the present invention is provided with back up pad 9 in electric actuator 1, described back up pad 9 is through output shaft 2, the output shaft 2 of described electric actuator is by key 3 connecting band moving cam 4, described cam 4 connects engaged wheel 5, described engaged wheel 5 connects push rod 7 by bearing pin 6, and described push rod 7 is arranged on slideway 8; Described slideway 8 is arranged in back up pad 9 by flange 10.
In the present invention, described cam 4 has the curved profile of diameter change, and the ratio of described diameter change is greater than 5 to 10 times.
Principle of work of the present invention is: cam 4 installs output shaft 2 end with electric actuator by key 3, and output shaft 2 is uniform rotation, and rotational angle can be arranged.The rotating band moving cam 4 of output shaft 2 rotates, and the rotation of cam 4 drives engaged wheel 5 to move up and down, and engaged wheel 5 drives push rod 7 to run on slideway 8 by the connection of bearing pin 6.Thus realize the object of vast scale gearshift adjustment.This patent, by the design of cam profile curve, reaches the object of speed change, and governing speed can be greater than 5 to 10 times.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
