Abstract
The utility model discloses a force moment protection sensing device of an electric actuator, which is characterized in that a force moment detecting bellcrank is arranged on a middle shaft arranged at one side of a butterfly group spring, which is connected with a spur gear by a fan gear, the spur gear is arranged at the output shaft end of the sensor, which is acted on the tangential of the endless screw by a worm gear, making the butterfly spring is deformed and moved, and making the sensor rotated or moved rectilinearly. The weak voltage or feeble current or pulse form is reacted to the main control system by the angle- moving sensor or rectilinearly-moving sensor, to instantly detect and react the force moment during the process of the device working. The utility model has high reliability, good practicability, low production cost and processing difficulty and high intelligent degree, which is easy for popularization.
Description
Technical field:
The utility model relates to the technical field of robotization control, a kind of force moment protection sensing mechanism of electric actuator, particularly its internal mechanical syndeton specifically.
Background technology:
Existing force moment protection mechanism is a pure mechanical type, and it exists shortcoming as follows: when 1, revising moment values, need adjust gland nut with machine tool; 2, can only stir microswitch by cam, cut off forceful electric power (also claiming primary power); 3, give master control system without any signal, can not carry out Based Intelligent Control.
Along with continuous advancement in technology, computer technology is used more and more wider, and existing product needed is to intelligent, integrated development.
Therefore, still need prior art is further improved.
Summary of the invention:
The purpose of this utility model is to provide a kind of force moment protection sensing mechanism of electric actuator; intelligent degree height; can be immediately moment values be fed back to master control system with light current pressure or weak current or impulse form, and obtain feedback, overcome shortcoming and defect of the prior art.
To achieve these goals; technical scheme of the present invention is: a kind of force moment protection sensing mechanism of electric actuator; it mainly comprises axis; one end of axis is provided with the input gear set; the axis place of input gear set one side is socketed with bearing; axis is fixed with worm screw near the middle section; the worm and wheel engagement; the other end place of axis is socketed with the butterfly spring group; it is characterized in that: the axis place of butterfly spring group one side is provided with moment and detects crank throw; moment detects crank throw and is connected with spur gear by sector gear, and spur gear is arranged at the input shaft end of sensor.
The utility model provides a kind of force moment protection sensing mechanism of electric actuator; it acts on the tangential of worm screw by worm gear; make the butterfly spring distortion produce displacement; make sensor rotate or straight-line displacement; by angle displacement sensor or linear displacement transducer; feed back to master control system with light current pressure or weak current or impulse form; moment values in the equipment work process is detected immediately and feeds back; this product reliability height; has good practicability; production cost and difficulty of processing are low, and intelligent degree height is easy to promote.
