Description
Technical field
The present invention relates to a kind of stroke protection mechanism, the stroke protection mechanism of especially a kind of microswitch.
Background technique
Microswitch control stroke mechanism be commonly utilized in aircraft electrical control system, by microswitch triggering with
Interrupt the rotation angle for carrying out control device output shaft, when microswitch failure cannot provide interrupt signal sometimes, output shaft meeting
Continue to rotate, caused by will being possible to because of overtravel phenomenon in device other components damage.Domestic control stroke is protected at present
The technology of shield mostly uses greatly sensor feedback output signal, and implementation manually controls, and this mode not enough automates, and needs artificially to grasp
Make fast and accurately, and sensor will receive surrounding environment influence and introduce risk, causes to fail or report by mistake.
Summary of the invention
The object of the present invention is to provide a kind of stroke protection mechanism of microswitch, the stroke that switch may be implemented is protected automatically
Protective function damages device internal component after avoiding overtravel, is not required to manually control, and has high degree of automation, work
Make safe and reliable feature.
The specific technical solution of the present invention is: the stroke protection mechanism of microswitch include microswitch component, bogie,
Retaining ring, shaft, shift plate, micro switch mechanism include microswitch, rocker arm, spring leaf, pin shaft, and rocker arm is mounted on pin shaft and can
Rotation, rocker arm side are arranged in the gap of shift plate, and the other end installs two spring leafs, and the spring leaf is located at two fine motions
Between switch；Bogie connects power intake, and trapezoidal annular groove is provided on the bogie, and retaining ring section is rectangle,
And be mounted in trapezoidal annular groove, shift plate is the terraced structure being made of two annulus, and wherein the part of major diameter is provided with appearance
Receive the gap of one end, the part of minor diameter is located in retaining ring, and is provided with the gap for accommodating retaining ring mounting ear, solid in shaft
Surely there is column, the column is located between the mounting ear of retaining ring.
At work, power input drives bogie rotation by driving motor to the present invention, and bogie drives retaining ring rotation,
Retaining ring drives output shaft rotation by mounting ear, meanwhile, the mounting ear of retaining ring drives shift plate to rotate together, after shift plate rotation,
When shaft rotates certain value, the gap of shift plate major diameter position contacts rocker arm, stirs spring leaf by rocker arm and rotates around pin shaft, touching
It sends out the triggering of microswitch component control circuit and interrupts.The present invention passes through shift plate open slot angle controller stroke output angle
The torque that protection mechanism acts is arranged by parameters such as ladder type annular groove angles in the thickness, outside diameter, bogie of retaining ring in degree
Numerical value Tn, as output torque Tc≤Tn, protection mechanism is failure to actuate, the normal output torque of device；When microswitch failure, turn
Axis can continue output torque, and as Tc > Tn, protection mechanism movement, retaining ring is slided in ladder type annular groove, terminate torque output, play
The effect of clutch protection, the present invention all use mechanical parts, realize automatic protection functions, improve the reliability of product.
