The circular arc automatic door has appearred in the prior art, the door machine of this circular arc automatic door uses the door machine identical with translation opposite opened automatic door, in the door machine, increase some connecting rods simultaneously, the end of connecting rod is fixed on the position of departing from the door-hinge certain distance on the door leaf, by driving mechanism drivening rod top linear slide in doorframe, the terminal pulling of drivening rod door leaf rotates around door-hinge, makes the reciprocating motion of driving mechanism end be converted to the rotation of connecting rod end around door-hinge.But, connecting rod need stretch out outside doorframe in this structure, so that certain rotation space is arranged, this makes the part of door machine expose in the doorframe outside, be easy to because of bar things such as dust enter into the effective work that has influence on a machine transmission mechanism in the machine, working life is short; Owing to use connecting rod to drive the door leaf rotation, the load that makes whole door machine to bear is little simultaneously; When door leaf is subjected to big resistance, be easy to the problem that causes that connecting rod fractures, cause whole door machine to lose efficacy.
[utility model content]
The technical problems to be solved in the utility model is, exists because of the door machine partly exposes the problem that causes working life short outside doorframe at automatic every machine in the prior art, and a kind of automatic every machine of circular arc that can be sealed in fully in the doorframe is provided.
The technical scheme that its technical problem that solves the utility model adopts is: construct the automatic every machine of a kind of circular arc, comprise be arranged on the door machine casing in the circular arc automatic door doorframe and be arranged on the control system of motor in the casing, control machine operation, by motor-driven transmission mechanism, it is characterized in that, described transmission mechanism comprises by motor-driven tooth bar, is set in the gear on the output shaft, described wheel and rack is meshing with each other, and described output shaft is connected with door-hinge is coaxial.
At the automatic every machine of above-mentioned circular arc described in the utility model, described motor is connected with described rack drives by ball screw assembly.
At the automatic every machine of above-mentioned circular arc described in the utility model, also be provided with push rod between described ball screw assembly, and the tooth bar, the two ends of described push rod are hinged with described leading screw and described tooth bar respectively.
At the automatic every machine of above-mentioned circular arc described in the utility model, be provided with first chute in the described casing, described push rod is slidingly arranged in described first chute.
At the automatic every machine of above-mentioned circular arc described in the utility model, be provided with second chute in the described casing, described tooth bar is slidingly arranged in described second chute.
Implement the automatic every machine of circular arc of the present utility model, have following beneficial effect: comprise control system, motor, transmission mechanism by a machine is set, and transmission mechanism comprises by motor-driven tooth bar, gear; When control system control machine operation, the motor-driven tooth bar slides, make and rotate with the tooth bar meshed gears, rotate thereby make output shaft drive, realize rotating drive, and entire mechanism all is positioned at an inside of machine casing circular arc automatic door door leaf with the coaxial door-hinge that is connected of output shaft, no exposed part, thereby avoided magazine access door machine inside such as dust, a machine that guaranteed can effectively be worked, and has prolonged the life-span of door machine.And, utilize the rack-and-pinion engaging mechanism as transmission mechanism, make door leaf can bear bigger moment of torsion, transmission mechanism also is not easy to lose efficacy, and has guaranteed the reliability of door machine work.
Further, motor preferably is set is connected with described rack drives by ball screw assembly,, the little and stable drive of the noise when making the work of door machine, output torque are big; Ball screw assembly, is convenient as general part buying in addition, makes the easy process and assemble of whole door machine.
Further, preferably between ball screw assembly, and tooth bar push rod is set, the two ends of push rod are hinged respectively at leading screw and tooth bar, thereby reduce the rigid shock of leading screw to tooth bar, avoid rack and pinion to take off tooth or stuck inefficacy situation when transmission.
The utility model is described in further detail below in conjunction with drawings and Examples.
