Abstract
The utility model discloses a multiple spindle synchronous feedback device of an actuator, aiming to improve the prior actuator which has no synchronous detection and disclination checkout functions, the lack of the functions leads to the fact that multi-group actuators can not run synchronously. Therefore, a rotation disc and an optical gate component are assembled in the actuator, wherein, the rotation disc is arranged on an output rotating shaft inside a gear box and is provided with a plurality of nicks which are non-light tight; the optical gate component is arranged on the outer margin of the rotation disc and comprises a luminescence element and a sensitization element. The rotational angle and the rotational displacement of the rotation disc can be detected by the optical gate component matched with a detection hole; the detection signal can be taken as the synchronous control feedback signal of the multi-group actuators, so that the multi-group actuators can synchronously run.

When carrying out with two or more sets actuators, because having, known actuator do not detect synchronously and function that swing offset detects, so can't reach the requirements of many group actuator synchronous operations with moving running; Yet, on the practice of actuator, the actual demand that links running with many groups actuator is often arranged but; Therefore, known actuator structure has the necessity that is improved, so that its realistic demand;
Moreover its gear-box of known actuator mainly is to cover institute mutually by upper and lower cover 17,18 to constitute, and the pivot 122 of each gear 121 of gear train 12, then as shown in Figure 1, for direct pivot is equipped on the upper and lower cover 17,18; The structural design of this known gear-box, for industrial circle, the assembly of this gear set members and in the future overhauling, unsatisfactory, because gear train is when carrying out assembly, gear is difficult for reaching intended orientation; And when safeguarding, this gear set members then had the possibility of being scattered after this loam cake was disassembled; But the design of the known actuator structure of part is not attained perfectly, can't meet the actual demand of industrial circle, and significantly necessity of improvement is arranged further in addition.
Summary of the invention
Main purpose of the present utility model is to provide a kind of actuator multiaxis synchronous feedback device, by set rotating disc and optical gate member on output revolving shaft, makes output speed, angle of swing of actuator etc., is all detected and learns; Thus, this detects the synchronization control feedback signal that signal then can be used as many group actuators, thereby many group actuators are carried out with moving running.
The utility model is achieved in that its actuator mainly is made of motor and gear-box, is equipped with gear train in this gear-box, gear train with the output revolving shaft of output gear as rotary output axis; Be characterized in being equipped with in the actuator rotating disc and optical gate member, wherein rotating disc is provided on the output revolving shaft of gear-box inside, and offer the breach of most light-permeables on rotating disc, the optical gate member is provided in the outer rim of rotating disc, and wherein the optical gate member includes illuminating part and sensitive piece.
Side at the inner adjacent teeth wheels of gear-box also can set a dividing plate, makes gear-box inside be formed with one the space is set every establishing, and makes the output revolving shaft of output gear wear dividing plate and the space is set and is hubbed at the loam cake of gear-box; Set rotating disc being provided with on the output revolving shaft in space, and set the optical gate member in the outer rim of rotating disc.The breach of offering on the rotating disc can be circular hole, short slot etc.
For the location sensing susceptibility that makes the optical gate member increases, the optical gate member can comprise two and above illuminating part and sensitive piece.
The breach of offering on the rotating disc is used so that the light penetration that illuminating part sent of optical gate member, thereby whether the light that the sensitive piece sensing illuminating part that can see through the optical gate member sends is intercepted, and detect the rotation angle and the rotation displacement of rotating disc, this detects the synchronization control feedback signal that signal then can be used as many group actuators, is carried out with moving running so that organize actuator more.

Embodiment
About the utility model for reaching above-mentioned purpose, the technology that is adopted, means and other effect, now lift a preferable possible embodiments and cooperate graphic detailed description as after, believe the above-mentioned purpose of the utility model, feature and other advantage, when can by one deeply and concrete understanding.See also shown in Figure 2, the synchronous feedback device of a kind of actuator multiaxis that the utility model embodiment is provided, it mainly is to constitute by set dividing plate 30, rotating disc 32 and optical gate member 33 in actuator 20; Wherein:
This actuator 20 is made of motor 21 and gear-box 22, thereby can see through gear train 23 runnings in motor 21 driving gearboxs 22 and rotate output; This gear-box 22 is to be covered to lock to establish by 221,222 of upper and lower covers to constitute, and is equipped with gear train 23 in gear-box 22, and gear train 23 is to export as rotating with the output revolving shaft 232 of output gear 231; The output revolving shaft 232 of this output gear 231 sets mutually with bearing 241, ball bearing 242, axle sleeve 243, Ai Kemu nut 244, Ai Kemu screw rod 245, thereby makes rotation output smooth and easy;
The utility model is in a side of gear-box 22 inner adjacent teeth wheels 23, be equipped with a dividing plate 30, make gear-box 22 inside be formed with one space 31 is set, and make the output revolving shaft 232 of output gear 231 wear dividing plate 30 and space 31 is set and is hubbed at loam cake 221 every establishing; On the output revolving shaft 232 that space 31 is set, set rotating disc 32 (can be black POM matter material), and on rotating disc 32, offer most holes (or detecting breach) 321 of detecting, and in a side of corresponding rotation dish 32, be equipped with optical gate member 33, this optical gate member includes illuminating part and sensitive piece, detection hole of offering on the rotating disc or breach are used so that the light penetration that illuminating part sent of optical gate member, thereby whether the light that the sensitive piece sensing illuminating part that can see through the optical gate member sends is intercepted, and then can cooperate with detection hole 321 through optical gate member 33, and detect the rotation angle and the rotation displacement of rotating disc 32, this detects the synchronization control feedback signal that signal then can be used as many group actuators 20, and many group actuators 20 are carried out with moving running;
