Description
Technical field
The utility model relates to a kind of intelligent electric actuating mechanism torque master.
Background technology
Intelligent electric actuating mechanism is the important device of by-pass valve control, is to constitute the indispensable elementary cell of various pipe systems; To the accurate detection of intelligent electric actuating mechanism output torque, control to preventing because of the improper damage of valve, intelligent electric actuating mechanism that over torque causes, and even the normal operation of pipe system has and important protective effect.
The general following dual mode that adopts generally detects to torque in intelligent electric actuating mechanism manufacturer at present: first kind is the difference of the concrete numerical value of electric current when utilizing the output load of motor difference, confirms the actual value of intelligent electric actuating mechanism output torque again through certain conversion; Second kind is the axial thrust of utilizing worm screw in worm gear, the worm transmission pair, controls worm screw axial displacement through at the worm screw two ends butterfly spring being set, and detects axial displacement, concerns the actual output of conversion place intelligent electric actuating mechanism torque according to stressed again.First kind of mode during because of the motor actual motion when identical output electric current influenced by temperature, input voltage, sea level elevation to occur changing accurately to detect the actual output of intelligent electric actuating mechanism torque.The second way changes when not obvious very for a short time because of axial displacement when torque when reality is used, and accomplish accurately to detect to be difficult to, and intelligence detects roughly, can accomplish that promptly torque capacity detects, but can't be accurately the overall process of torque variation be detected.
Summary of the invention
Goal of the invention: the purpose of the utility model is the deficiency to prior art, and a kind of intelligent electric actuating mechanism torque master accurate and whole process detection in good time of measuring is provided.
Technical scheme: in order to realize the foregoing invention purpose, the technical scheme that the utility model adopted is:
A kind of intelligent electric actuating mechanism torque master; Comprise housing and the worm and gear that is arranged in the housing; Worm screw is rotatably connected with housing; Between worm screw and housing, be socketed with axle sleeve and two sensing pressing plates that cooperate extruding successively, between two sensing pressing plates, be provided with sensing pad and sensing rubber cushion, one of them sensing pressing plate is provided with the deformation detector that is used to detect sensing rubber cushion deflection.
Described sensing pressing plate is provided with the window that is used to place deformation detector, and described deformation detector embeds wherein, is useful on the pressing plate of restrained deformation detecting device displacement in the arranged outside of described deformation detector.
The worm screw of worm and gear receives axial thrust when intelligent electric actuating mechanism moves; Axially there is the moving axle sleeve that drives of certain string that thrust is passed to the sensing pressing plate; The relative displacement that the sensing pressing plate limits sensing pad, sensing rubber cushion causes that the sensing rubber cushion of rubber material is out of shape; Change thrust into equally distributed pressure simultaneously and pass to the sensing pad, detect the sensing pad because of the micro-deformation output electric signal that pressure produces, calculate the intelligent electric actuating mechanism torque through deformation detectors.
Beneficial effect: the utility model compared with prior art, its beneficial effect is:
The utility model is converted into micro-deformation through designing cleverly with the worm screw axial thrust; Trace deformation is converted into electric signal through deformation detectors; Detect value of electrical signals and can know the output torque; Avoided the detection current of electric affected by environment bigger like this, also solved simultaneously and detected that accuracy of detection does not reach the problem that control accuracy requires in the displacement mode; Improved accuracy of detection; Can accomplish axial thrust provided feedback signal accurately, timely; Improved when intelligent electric actuating mechanism is on-the-spot to be used various requirement to the torque control accuracy; Improved the usable range of intelligent electric actuating mechanism in various pipe systems greatly, effectively prevented to have protected pipe system normally to move because of the improper damage of valve, intelligent electric actuating mechanism that over torque causes.
