Description
Technical field
This application involves relative motion differential seat angle inter-agency under practical working situation and mechanism torque measurement techniques fields, especially
It is related to door lock mechanism unlock angle and unlocks the technical field of torque measurement.
Background technique
In the automatic door mechanism of Modern Traffic and smart home field, on the one hand need to realize under the drive of power end motor
The door leaf automatic open/close door of load end, still further aspect load end have self again and door leaf are hindered to force to beat under external force
The function of opening.To guarantee communications and transportation or house security.If this function of self hindering is by automatically controlled realization, there are disadvantages
End can utilize to some criminals if power down back door may turn on easily or power down back door can not open, this to set
There are security risks in transport process for meter, it is easy to cause super casualty.Therefore, this kind of automatic door mechanism is all deposited
In a critical component --- door lock mechanism.The dynamic input terminal of door lock mechanism and load connecting pin；Power end is connected to motor,
Input switch door power；Load end is connect with lead screw, and the rotary power of output is converted to the linear motion of door leaf.Power end
The movement of normal switch door may be implemented, but input enabling power if it is from load end, then mechanical structure is just locked in door lock mechanism
Extremely, the lead screw rotation for hindering connection door leaf, achievees the purpose that door leaf is hindered to open.Therefore, this kind of door lock mechanism is defeated in power end
When entering power enabling, just there is a unlocking motion, is exactly the inside unlock for realizing door lock mechanism after power end rotates by a certain angle
Movement, load end can open door leaf under external force at this time or power end drives load end lead screw to realize that door leaf is beaten
It opens.Both normal switch gate functional requirement had been met, safety requirements is also met.But door lock mechanism due to part process, installation,
The factors such as assembly, so that the power end unlocking motion of novel door lock mechanism for door will appear and can not unlock, unlock angle is excessive or too small, solution
The failures such as lock knob square is excessive or too small.In response to this, it is necessary to which a kind of measuring device and method can examine door lock mechanism
Quality guarantees that door lock mechanism works normally in mechanism.
It is exactly to require that door lock mechanism, which unlocks angle measurement, when meeting actual loading, realizes the door lock mechanism solution locking angle
Multiple measurement of the degree with unlock torque in one week.Existing torque test equipment has the torque in measuring device rotation process
Variation, or the torque of load driving；Angle measurement is more used in measurement revolving speed, even measurement angle, also up to not
To differential seat angle measurement request.Relative to the requirement of door lock mechanism, the measurement of these equipment is had a single function.Decompose door lock mechanism measurement
Function realizes mainly there is the requirement of the following aspects specific to technology.1, the dynamic input of equipment is able to satisfy door machine structure
Switch gate power；2, the unlock torque for being input to door lock mechanism being capable of real-time measurement；3, it is capable of measuring the solution locking angle of power intake
Degree, is exactly that door lock mechanism power end starts turning, and until load end has rotation sign, the angle of power end rotation at this time is exactly to solve
Locking angle degree.4, resistance is needed in load end, to simulate the load end resistance of door lock mechanism in actual operation, guarantees the solution locking angle
Operating condition when degree, unlock torque measurement is consistent with real work.5, since measurement needs to simulate actual condition, fictitious load is hindered
The resistance of power device will have calibration function, to guarantee that measurement data is true and reliable.
Under normal circumstances, angle measurement uses encoder, but it is unable to bearing torque in the measurements.If encoder pacified
Mounted in two end of equipment, high to measuring device design requirement although not stressing then, installation is also complicated, at high cost.Door lock mechanism
Power is needed to input in the measurements, load end has Resistance-load, if power input device and load simulating device are all fixed
, then door lock mechanism installation process is with regard to more complicated；Angle measurement is unlocked, if measuring rotation using encoder in power end
Angle must have feedback signal in load end.If feedback device is the movement for monitoring load end, there is movement just output letter
Number, then this action signal threshold value setting requirements is just high, if set it is low, it is anti-interference to be eager to excel, just to monitoring device circuit requirement
Height brings angle measurement error with regard to big if setting height.Additionally, due to door lock mechanism internal stress, unlocks and rotate in power end
In the case of sufficiently unlocking, stress release is had, load end intermittence, of short duration time transfer are shown as, then power end relies on
Load end acts feedback signal measurement unlock angle, can there is false measurement.

Step 3:, using third guide rail slide block 32, the 4th guide rail slide block 33 is along the first guide rail by load resistance simulator
2, the second guide rail 3 is close to door lock mechanism 19.Third polished rod 22 is connect with the load end mounting hole of door lock mechanism 19, utilizes pedestal
The fixed device of 31 fixation hole 35.
Step 4: set measurement parameter in operation system interface, rotation speed, resistance, testing time, above and below torque
Limit, unlock angle bound etc..
Step 5: stepper motor is set as shutdown direction, after rotation.If the angled output of load end can stop,
This movement purpose is to eliminate enabling direction, the stress inside latch mechanism 19.
Step 6: stepper motor is set as enabling direction, rotated along enabling direction, then load end angle measurement if there is
Transfer, and be after being greater than certain angle, then stop operating, record power end measurement angle.Then unlock angle just are as follows: θ=-.And torque in record rotation process.One-shot measurement finishes.
Step 7: measurement data is compared with setting data.If unlocking angle is more than or less than setting value, or the solution of record
Lock knob square is more than or less than setting value, then stops measuring, jump to the tenth step；If unlocking angle and unlock torque data just
Often, then the 8th step is executed.
Step 8: stepper motor is set as enabling direction, next test angle is rotated to, prepares measurement.
Step 9: repeating the 6th step~the 8th step, until the measurement point being circumferentially arranged, all measurement terminates.
Step 10: the enabled failure of stepper motor.35 fixing bolt of pedestal is unclamped, load resistance simulator is led using third
Rail sliding block 32, the 4th guide rail slide block 33 is along the first guide rail 2, the second guide rail 3 far from door lock mechanism 19.By connector 21 and door lock machine
The connection of 19 load end extension of structure is unclamped, and load end angle measurement unit utilizes the first guide rail slide block 27,28 edge of the second guide rail slide block
First guide rail 2, the second guide rail 3 are far from door lock mechanism 19.The axis connection of 4th shaft coupling 18 and door lock mechanism 19 is unclamped.Then it tears open
Door lock mechanism 19 is unloaded, next door lock mechanism is installed, repeats the first step~the 9th step.
