Description
Technical field
The present invention relates to the technical field of sensor calibration apparatus, especially a kind of demarcation branch of static torque sensor
Frame.
Background technology
Sensor is a kind of detection means, can experience measured information, and the information that will can be experienced, by a set pattern
Rule is for conversion into electric signal or the information output of other required forms, to meet the transmission of information, processing, storage, display, record
With control etc. require.Sensor is the primary link realized automatic detection He automatically controlled, and application is very wide, in modern work
During industry production especially automated production, the parameters in production process are monitored and control using various sensors,
Equipment is operated in normal condition or optimum state, and product is reached best quality.In sensor before use, generally requiring
Sensor is demarcated, the demarcation of so-called sensor, refer to the relation established by experiment between sensor output and input
And determine such a process of error under different use conditions.Design, manufacture and use of the demarcation of sensor to sensor
It is all significant.In industrial automation detection device, the sensor that mainly uses have displacement transducer, weighing sensor with
And torque sensor etc..However, the demarcation supporting structure of existing static torque sensor is complicated, manufacturing cost is high, using not
Just, calibration range is small, and the manufacturing to enterprise brings many puzzlements.
The content of the invention
The invention aims to solve problem present in above-mentioned background technology, there is provided a kind of static torque sensor
Demarcation support, by the improvement of structure, reduce manufacturing cost, simple in construction, easy to use, reliable, calibration range is wide.
The technical solution adopted for the present invention to solve the technical problems is：A kind of demarcation support of static torque sensor,
Including counterweight hook, counterweight, supporting arm and lock sleeve, the supporting arm is horizontal setting, and the one of the supporting arm
End is connected to the lock sleeve, and the other end of the supporting arm hangs with the counterweight hook, and the counterweight is positioned over the counterweight
The lower end of hook.The moment of torsion that static torque sensor measures is checked by moment of torsion caused by the counterweight hook and counterweight,
Structure, principle are simple, and manufacturing cost is low, easy to use.
Further, the supporting arm is located at one end annular of the counterweight hook and is provided with stopper slot, and the counterweight is hung
It is hooked in the stopper slot, accurate positioning, stated accuracy is high.
Further, the center of the stopper slot and the centre distance of the lock sleeve are A, and the A is integer, is easy to count
Calculate, it is easy to use.
The present invention design principle be：Using the counterweight hook and counterweight under the arm of force of certain length caused by
Moment of torsion come check static torque sensor measurement moment of torsion, that is, realize the demarcation of static torque sensor.
The beneficial effects of the invention are as follows：Structure, principle are simple, can effectively realize the on-line proving of static torque sensor,
It is low to reduce manufacturing cost, it is easy to use, reliable.

Embodiment
In conjunction with the accompanying drawings, the present invention is further explained in detail.These accompanying drawings are simplified schematic diagram, only with
Illustration illustrates the basic structure of the present invention, therefore it only shows the composition relevant with the present invention.
A kind of demarcation support of static torque sensor shown in Fig. 1 and Fig. 2, including counterweight hook 1, counterweight 2, supporting arm
3 and lock sleeve 4, the supporting arm 3 is horizontal setting, and one end of the supporting arm 3 is connected to the lock sleeve 4,
The other end of the supporting arm 3 hangs with the counterweight hook 1, and the counterweight 2 is positioned over the lower end of the counterweight hook 1.Pass through
Moment of torsion caused by the counterweight hook 1 and counterweight 2 come check static torque sensor measurement moment of torsion, structure, principle are simple,
Manufacturing cost is low, easy to use.
One end annular that the supporting arm 3 is located at the counterweight hook 1 is provided with stopper slot 5, and the counterweight hook 1 is hung on
In the stopper slot 5, accurate positioning, stated accuracy height.
The center of the stopper slot 5 and the centre distance of the lock sleeve 4 are A, and the A is 200mm.
The weight of the counterweight hook 1 is 1KG, and the weight of the counterweight 2 is 2KG.
As shown in figures 1 and 3, one end of static torque sensor 7 is connected with power transmission shaft 6, and the electricity of static torque sensor 7
It is connected to Measurement and Control System；During demarcation, the other end of static torque sensor 7 is fixed, and lock sleeve 4 is fixed on into power transmission shaft
On 6, and supporting arm 3 is set to be horizontal placement；The moment of torsion that static torque sensor 7 is measured is reset, and hangs up counterweight hook 1,
Whether the moment of torsion for observing the measurement of static torque sensor 7 is 2Nm, places into counterweight 2, the measurement of observation static torque sensor 7
Whether moment of torsion is 6Nm, is sequentially placed into multiple counterweights 2, and whether the moment of torsion of the measurement of observation static torque sensor 7 is theoretical torque,
By adjusting the coefficient of static torque sensor 7, the moment of torsion that static torque sensor 7 measures is set to be consistent with theoretical torque,
Complete the demarcation of static torque sensor 7.
Structure of the present invention, principle are simple, can effectively realize the on-line proving of static torque sensor, reduce manufacturing cost
It is low, it is easy to use, reliable.
